(Part 2) Best general engineering books according to redditors
We found 6,203 Reddit comments discussing the best general engineering books. We ranked the 2,640 resulting products by number of redditors who mentioned them. Here are the products ranked 21-40. You can also go back to the previous section.
Forgive the cheap plug, but I just wrote a whole book on this, to appear in Feb 2012, titles "Space Chronicles".
I originally called it "Failure to Launch" but the publishers nixed the title, citing it was too depressing.
Here's the listing for a pre-order, if interested. http://www.amazon.com/Space-Chronicles-Facing-Ultimate-Frontier/dp/0393082105
Material science and textiles, while extremely related are quite different in the classroom. I had MSE classes and my intro textbook was the one below. It mainly dealt with materials on a molecular level, while the textile courses consisted of the processes involved with creating the fabrics.

Something every GIS professional should read, and this is a shining example of techniques used, like the ramp used on the CDC data.
Here's my rough list of textbook recommendations. There are a ton of Dover paperbacks that I didn't put on here, since they're not as widely used, but they are really great and really cheap.

The first Muslim astronaut, Sheikh Muszaphar Shukor, from Malaysia had the problem of not knowing what direction to face when praying in orbit. A conference of scientists and scholars determined that facing the earth's surface would suffice.
I learned about this while reading Packing for Mars by Mary Roach. A rather interesting book about the difficulties and funny peculiarities of manned space exploration.
Since I read this for physics coursework, I've been convinced that we should colonise Mars and as soon as possible.
Space Chronicles by Neil deGrasse Tyson.
Looks good!
STEM generates wealth. Good message.
But apace advocates have been saying this since the 1960's. Neil's not bringing anything new to the table. This 2012 testimony didn't generate much support from policy makers. Neither did the book he published in 2012.
Space advocates can point to huge benefits generated by research from the 1950's and 60's. Not all of it was NASA R&D. Some of it was military and commercial. A few of the more prominent:
Miniaturization of electronics -- Rockets and missiles needed compact, low mass electronics. U.S. funded R&D helped put American companies at the forefront of an electronics revolution. There were already transistor radios around when NASA formed but the R&D helped accelerate trends like Moore's Law.
Communication sats. Generally not NASA's but it's hard to imagine commerical entities launching satellites if NASA and the U.S. military hadn't blazed a trail. These are huge beneficial spin off from the space program.
Weather sats. Again, not NASA but enabled by development of launch technology More accurate weather prediction has saved lives, prevented property damage and enabled farmers to produce more food.
Will future NASA endeavors generate such dramatic spin offs? If that could be solidly demonstrated, it'd be easier to persuade policy makers. I certainly don't regard it as a given.
One of the rallying cries has been Colonize Mars! With huge, disposable rockets like the SLS. Basically Apollo rockets redux. The Apollo trips to the moon were about 10 billion a pop. It is likely SLS trips to Mars every two years would be even more expensive. Settling Mars would take a long sustained effort taking decades or maybe even centuries. Would policy makers support that sustained effort? An expensive, high profile program would be a lightning rod for policy makers that want to appear fiscally responsible. I'd give the program two presidential cycles. Agaiin, Apollo redux.
Some critics maintain the chief benefit of SLS and Orion is providing employment in certain congressional districts. Pork, in other words. I tend to agree. I don't think NASA is blazing new trails with SLS and Orion.
Many serious proponents of exploiting and settling space call for improved robotics and In Situ Resource Utilization (ISRU). Already British Petroleum is using remotely operated vehicles to build sophisticated infrastructure on the sea floor where humans can't reach. Should NASA invest heavily in improved tele-robots, this could potentially generate enormous spin offs. I can see tele-robot operaters donning their motion capture suits in their living rooms. No need to commute to work. Besides working on the lunar surface or on asteroids, tele-robot operatros could do work in the deeper mines, high mountain tops, the sea floor. As well as hazardous disaster areas like Fukashima after a tsunami.
Summary: "A penny for NASA" is too simplistic. Some NASA projects might have big pay offs. Others are likely dead ends. If we want to persuade policy makers and fire up the public, we need to place our bets on good horses.
BBC made an hour long documentary about this project and it's well worth the watch. It's available on YouTube here: https://www.youtube.com/watch?v=xYoLcJuBtOw
There's also a book written by Dyson's son, although I have not yet read it so I can't attest to how good it is. This is it here: http://www.amazon.com/Project-Orion-Story-Atomic-Spaceship/dp/0805059857
If you want to really do your homework, start with the primary source. The name of these structures comes from Gerald K. O'Neill, and his work The High Frontier: Human Colonies in Space.
I believe this book has been referenced at least once on the channel. I haven't read it myself, but you could do worse than starting there.
Mark's Handbook for Mechanical Engineers
this book covers the bread and butter of what CHE is. Which is mass/energy balances (basically, what goes in equals what comes out.)
you can start with that and later move onto the more "advanced" topics such as transport, thermo, fluids, etc etc
This book is pretty good too and touches on data manipulation using maps.
TRIGGER WARNING: CANADIAN AMAZON
Elementary Principles of Chemical Processes
https://www.amazon.com/Elementary-Principles-Chemical-Processes-Richard/dp/047168757X
The obvious choice is the introductory holy bible of MSE. If you already know the basics of how materials are categorized and behave, that book /u/Tartarus116 posted looks pretty good.
Understanding Engineering Mathematics by John bird. It's available for free download on gen.lib.rus.ec. It has tons and tons of fully worked examples and covers just about everything from 1+1 to laplace transforms.
You will probably want to develop a more conceptual approach to mathematical problem solving after you are done with it, but you will cross that bridge when you get there. Just in case you are curious about what that even means you can find Mathematical Methods for Physics and Engineering for free on genlib too. This is not the book you're looking for right now though.
Elementary Principles of Chemical Processes was the book used in my first ChemE major class. It discusses a lot of the big ideas in chem e without getting too specific. You can find the international edition for around 10 dollars online.

Why I don't give a shit about coffee machine expenses, office furniture, etc:
Firstly, and this is important, Star Citizen is an extraordinarily challenging game to write from a technical perspective (even Derek says that they
can't builddon't have the tech for it). Extraordinary tech requires extraordinary engineers.There is a long history of how various companies and colleges try to attract the best and the brightest. The first company that I know of which had to attract extraordinary engineers was General Atomic after WWII, which started working on Project Orion. Remember how your parents would give you pushes on the swing to make you go higher/further? Project Orion was basically that, except you're a spaceship and the push is really a nuclear explosion. Do you think I'm kidding? I'm not. So you're detonating hundreds of the most dangerous kind of bomb known at the time with specific timing in sequence: things have to go right. Therefore, you need the best engineers to work on it.
The facilities at the General Atomic campus were extensive, featuring an enormous library in the center that was shaped to be the same size of the spaceship they were trying to build. Other details can be found in George Dyson's book, but suffice it to say that General Atomic was able to recruit many of the Project Manhattan veterans because of some of these benefits and amenities: not all decisions come down to salary.
Google is a much more recent example; like General Atomic, Google wants the best. How does Google attract and retain the best engineers? Perks are a big, and well-documented, part of that. Just look at all these articles about the perks that Google employees get: https://www.google.com/search?q=general+atomic&ie=utf-8&oe=utf-8#q=google+perks.
Colleges do the same thing to try to get the best students to attend: they have large campuses with beautiful architecture. A state-of-the-art athletic center with more racketball and squash courts than would ever be used. A program to allow you to rent Picassos to hang in your dorm room. Hell, the school I work at has a parents association whose sole job is to bring the teachers lunch/breakfast once a month. I'd have left to be closer to friends/family long ago if it weren't for this (and other similar perks).
It's really clear to me that CIG is trying to do exactly this. I'm really surprised Derek hasn't mentioned this, but they have a full kitchen in the new California studio. Producers constantly talk about how they're working to make the engineer's lives better, sometimes that involves running errands or getting dinner. The mural on the wall helps people to take pride in their work (and is beautiful besides). A nice coffee machine and elegant furniture are ways to retain the amazing employees you have. That's part of the cost of hiring the best. Can you go overboard with it? Of course. Have they? Consider that this $20,000 coffee machine is less than 0.02% of their total crowdfunded number. They can afford it. And the employees deserve it.
Welcome to the real world, Derek. You can't just throw money at people and expect them to be inspired and give you their best. And you certainly can't do it when you're paying these people less than what they would get paid at other companies, no matter how awesome your project is.
This is the best answer. And the reason why the spacecraft computers are 5-10 years behind commercial technology.

Shigley's is great for learning how to design and why you design the way you do. It's the book I used in college and still reference at work. I'm not so sure it'd be great for a novice engineer. For a more practical approach, I'd recommend a few below (not necessarily in this order):
A nice free reference manual that includes all sorts of design equations is the NCEES reference handbook. I used it back when I took my FE exam (the first exam you take before you become what's call a "Professional Engineer" in the US). It's a nice PDF to have around, though it doesn't go into a lot of explanation as to what the equations are.
A few web resources I use are: http://www.engineeringtoolbox.com/, http://www.roymech.co.uk/
I'm sure I'll think of some more and, if I do, I'll update this post.
Hope that helps.
I recently read Packing for Mars which is a great read for anyone interested in the nitty gritty parts of human space travel you normally don't hear about.
In the end she states that with ~$500B NASA could take a manned mission to Mars. I'm all for it. I feel like there's a major brain drain in this country with the sciences taking a back seat to defense.
On top of the recommendation for the PE review book. Grab a copy of Roark's Formulas for Stress and Strain. I think the first edition was written in 1934, and its still in print.
Hundreds of solutions to many types of beams, plates, pressure veseels, and misc other problems. If you are doing much FEA or stress analysis at work, this book is a must.
http://www.amazon.com/Roarks-Formulas-Stress-Strain-8th/dp/0071742476
Coming from a GeoSci background, you may have already used Callister, but if not, it is my most highly recommended textbook. Of all the textbooks. It is simply amazing. If you are beyond that already, the deeper book I would recommend is Meyers and Chawla which is also an amazing book, but much more difficult to get a handle on. Meyers and Chawla is what I learned from at the graduate level in Materials Engineering, and indeed it is quite heavy on the details and equations. That being said, when responding to almost all questions with regards to materials, the first place I look is Callister. The last time I used Meyers and Chawla was looking into the specific mechanisms and modeling methods for creep. If you get and understand M&C you will probably know more theory than anybody else at your knew job.
BMW as recommended previously. The other Bible for spacecraft design is SMAD.
http://www.amazon.com/Mission-Analysis-Design-Technology-Library/dp/1881883108/ref=pd_sim_b_1
I also have that book. I think it's great if you already understand orbits. If you don't, it might be a little too technical. However, to anyone that already has a base in orbits, that is a great book.
Another good one!
Machine Design by Norton
Theory of Machines and Mechanisms by Shigley
are considered the two bibles on machine design and are common in machine design courses.
Materials Selection in Mechanical Design by Ashby
The Machinery's Handbook is a must have and I assume you already know about this.
Mechanisms and Mechanical Designs Sourcebook is good to help spark ideas or solve problems. There are other books along the same lines.
There's information on tolerancing and machining in The Machinery's Handbook especially. I'm not sure on other resources for those. There are books on manufacturing processes that'll discuss the tolerances capable and design limitations.
Here you go.
You miss the implications.
I used to do acoustical engineering for wastewater treatment plants. Human feces has "about" the same density of water for large variations in "about." There's actually a fair amount of science to this that the OP simply ignored; one of those "you know you're an engineer if..." jokes that ends with "you've ever modeled a horse as a sphere" and this is along the same lines.
The density of human feces depends an awful lot on water and gas content. Considering approximately 70% of human feces is e.coli^1, and considering the density of e.coli has actually been the subject of some study^2, saying "the density of this is 1" is a gross approximation that pretty much demonstrates that your source doesn't, well, know his shit.

Here’s a pdf of Fundamentals of Metallurgy by Sheshardi Seetharamen. Helped me a lot while I was in school, especially for chemistry.
The go to book for metallurgy / engineering (and the most recommended here) is Materials Science and Engineering: An Introduction by Callister
Beam Equations for how far it will bend, and the formula stress=M*y/I.
Notice both are inversely proportional to the second moment of area (I), which for a circular tube is given by the second equation on this list.
Roark's has a far more complete list of beam scenarios, the seven in that image may not cover your use cases.
Edit: Here's a scan that was lifted from an older edition of Roark's. It should have anything you're looking for.

If you had to just pick one I would choose between The Backyard Beekeeper and The Beekeeper's Bible.
I also highly suggest doing the following:
"If engineering were easy, they would have sent a boy with a note."
Seriously there aren't any shortcuts. Either you learn the fundamentals or you don't. But if you want a really good general reference book, get The Mechanical Engineering Reference Manual
Other useful references:
In actual practice, unless we are launching things into space or making them fly through the air, a lot of engineering is just picking thinks that we know will work by experience (if a 1" square tube will work let's use a 2") or by consulting with vendors.
How to lie with maps, great book
https://www.amazon.com/How-Lie-Maps-Mark-Monmonier/dp/0226534219 actually after reading this book, I'm more aware of how to visualize data more objectively
MechE and ChemEs both take Thermo, fluids, heat/mass transfer, process controls, and a lot of the same pre-reqs. What's different is the chemistry courses (so take orgo chem, Physical chemistry especially if you're still at uni), chemical kinetics, Material and energy balances, separations. Kinetics and separations, you should wait until you've got the chem courses done. Material and energy balances...get a copy of Felder and Rousseau (http://www.amazon.com/Elementary-Principles-Chemical-Processes-Richard/dp/047168757X)
An Introduction to Ordinary Differential Equations - $7.62
Ordinary Differential Equations - $14.74
Partial Differential Equations for Scientists and Engineers - $11.01
Dover books on mathematics have great books for very cheap. I personally own the second and third book on this list and I thought they were a great resource, especially for the price.
IMO schematic capture is just not the way to go. The applications of FPGAs are just too big these days for that low-level approach. (I am making a distinction between gate-level schematics and high-level descriptions, where you are describing huge blocks of complexity).
If you are doing small circuits that you would define by gates, you might even be better off doing it with discrete logic chips.
https://www.amazon.com/Learning-Art-Electronics-Hands-Course/dp/0521177235/
For small circuits in HDL, you can use free simulators.
Also I'm not sure what you mean by "older version of the programming language." Older chips sometimes mean you have to use the older development environments but the languages VHDL vs. Verilog or System Verilog is not really about old-vs-new.

Barring that, you could assume a rate for consumption of well, consumables (food, air, etc) and use that to find a mass budget for that. You can then assuming a launch cost per lb. Do something similar for your propulsion system, but assuming an engine with a certain ISP/propellant.

Marks' Handbook for Engineers - Great specific reference for tolerances and fits, also has good general design "common knowledge", formulas, and practice.
Mark's Standard Handbook for Mechanical Engineers.
At least it is a good reference whenever you want to remember how to do something, and learn some things you didn't learn in school.

It's Marks' handbook!

Search the right places and you can find non-official digital copies, if you know what I mean...
If you want to buy it, it's edited every ten years, and luckly, next year they will launch the 12th edition.
Roark's Formulas for Stress and Strain is the bible for such questions.
Any materials or mechanics student should own this book forever.
That map is a prime example of "How to lie with maps".
I read about it in Packing for mars - very interesting book, and full of information about space travel/exploration just like this.

Recommended reading: "How to lie with maps" by Mark Monmonier.
http://www.amazon.com/How-Lie-Maps-Mark-Monmonier/dp/0226534219
It's a great read... I think a lot of people look at maps and don't consider the cartographer (and his/her training, biases, etc.). If you guys like this article, you'll enjoy this book.
I work in the lab that is cited in your [3] reference. They actually cite the paper incorrectly. It should be Alberts, not Alperts. Check here for more and newer references. Be sure to check out the Ronca papers and the awesome NASA patch as well. The experiment found that the rat pups' vestibular systems did not develop properly. Once returned to earth, pups would not right themselves when dropped on their backs into an aquarium whereas pups not gestated in microgravity will roll before hitting the bottom. Mothers showed atrophy in muscles that are used to hold them off of the ground but, interestingly, had more muscle growth in areas that allowed them to turn at the core. Since every surface of the cage is essentially a floor they rotated along their longitudinal axis repeatedly. There were also neurological changes but I don't remember the details well enough to be able to elaborate without reading the papers again.
EDIT: This book is a pretty great read on a variety of "people in space" topics including, in part, the above experiments.
Well lets see. This year:
When did you last contribute anything sensible to anything?
The concepts of nucleation and growth are covered in most introductory materials science textbooks. Callister covers this topic at an introductory level in chapter 10 of his book.
If you want to delve deeper, you should look for books on solid-solid or liquid-solid phase transformations and/or kinetics. I can give recommendations if you are interested.
Hardenability is also an important concept to understand for anyone working in the steel industry or designing things made out of steel. I would expect most companies in this field to have some sort of on the job training, or at least the contact info for someone at their heat treatment supplier who knows what they are talking about.
Answer key:
(a) 8/3, assuming no momentum loss to the air.
(b) 64/9, treating the stings as massless ridged rods.
This is nowhere near as bad as physics problems get. You want to see tough look at this book.
This doesn't answer your question, but for some classes, there are very standard texts. It's anecdotal, but every single recent physics graduate student I've met used Jackson for electricity and magnetism (http://www.amazon.com/Classical-Electrodynamics-Third-Edition-Jackson/dp/047130932X). There are other texts out there I'm sure, but Jackson is by far the most common.
There are incompetent physicists, and there are incompetents who call themselves physicists. This response which says "experimental data is not to be debated" is representative of a field not just in crisis but about to experience an extinction event due to the truth of classical physics. If you want to really understand the depth of the problem in modern physics -- the fracture of reality and experiment - lots of math, little reason - read this essay.
Loud public pronouncements that show you don't understand something GUISED as a debate is DAMAGING. These posts are best to be ignored but I have encountered physicists who do google searches and come across people like "CSurveyGuy. " They actually seize his lampoon logic as justification that the hydrino is not worth a look.
There are all levels of people in every field - medical school grads, practiced family doctors, and neurosurgeons - a "doctor" is meaningless as to whether you can be taken seriously. Saying "I'm a physicist" is meaningless. Let's help clarify the prereqs to Mills.
- You need Jackson textbook level E&M to tackle Mills. This is graduate level E&M and many quantum physicists aren't up to speed on it. Since the electron is electromagnetic you need advanced E&M. If you don't have it, go back to school.
- You need strong intuitive capacity. Surprise, surprise, most physicists can't "see" new architectures very well. Brett Holverstott has done a masterful job read hi book for a start. Remember, special relativity was first published in 1905 (interestingly the year the Wright brothers first flew continously and only 10 years early Lord Kelvin physicist of the day said "flight of heavier than air objects is impossible."). Einstein's work was not "seen" nor accepted by ACTUAL elite physicists (not CSurveyGuys heckling in the town square). Proof? In 1931, "100 Authors Against Einstein" is published ( https://archive.org/details/HundertAutorenGegenEinstein ).
- You need to work very hard. Mills flat out has the most powerful intuition we've probably seen for nature in a long time. He "sees" things as obvious that aren't because he imagines nature. He designed the electron architecture - literally imagined reality - and then proved it works - the electron has spin etc. The electron solution is probably the Taj Mahal of science, if you will.
​
Many physicists are plug and chug quantum physicists who use the theory to crank out some marginal results. They don't have any vested in the truth, and may believe we cannot even find the truth about physical reality (it's unknowable to them - the uncertainty principle).
"CSurveyGuy" (and the bucket of similar internet dwellers) may want to actually solve something using this new theory - rather than flailing in public his lack of understanding. Statements like "big, horrible problems, like violating known rules of math" means this person is likely a time-waster. Reddit is not the place to do science.
If anyone is interested in an actual real debate on the theory - read "Reconsidering the validation of multi-electron standard quantitative quantum mechanics" by Dr, Jonathan Phillips (he is on the Navy's Energy Academic Group and his resume speaks for itself). Which is an all out attack on quantum mechanics that it isn't even a valid theory, as it is a jumble of theories none of which validate against experimental data. You can't read the abstract, you have to actually read the details. In that paper, near the end he says that CQM (Classical QM- i.e. Mills theory) DOES appear to be a valid theory since it matches energy levels of electrons and distinguishes them, and matches the experimental data that is the focus of the paper.
Addressing a smattering of other points
- Dr. Randy Booker was chair of UNC's physics department. The UNC chemist there Dr. Rick Maas said the "experimental data is so convincing it is time to stop the bickering about the theory". See the BBC Focus Article "Water Power" from 2005.
- 3 body problems go away because of the architecture of the atomic electrons
- Rathke was fully discredited by Mills who showed Rathke made mathematical errors that nullified all arguments. Since it has been 14 years since this all occurred the case is closed. Rathke was an ant who got crushed by a giant. The almost comedic part of this is that even Nobel laureates - who I have contacted - said they "haven't had time to look into the experimental evidence." A total revolution in science, but "my dog at the homework" type responses.
Since these back and forths won't end. It is best to disengage from internet "physicists" unless they talk about facts, not histrionic claims guised as "debate". I am sure if you took a Family Physician from the 1800s and brought him here today to talk about cloning sheep - he would flatly deny it is possible, and would rail against the theory, and would be an emotional mess because the world has changed. Physics was ripe for disruption - everyone admits that - and now we all play catchup.
You should read this book. It goes into every aspect of Mars settlement in detail.
It wasn't well worded. His point is that a great argument can be made that we have had both the technological and financial capability to start sending humans to Mars on the regular since the 1980's. What we've lacked is only the political and social will to do so.
NASA often comes up with fantastic new excuses for this, some more valid than others. "We need to learn more about the long term physiological effects" is valid, but is mostly invalidated by the tremendous amount of research that has already been done. When do we have, "enough"?
Saying we need this hibernation technology to do it is a lot like saying we need a better propulsion system to do it. We don't. Would it be nice? Sure. Is it an excuse for not going? Hell no.
For a much more in-depth analysis of this, and for a look at what is in many opinions a vastly superior way to do approach this, check out that book.

Edit: As an added note, Elon Musk has a similar outlook. The implementation he's seeking is significantly different, but it has the same attitude. But unlike Zubrin, Musk had the capital to say, "screw it, I'll do it myself".

For plastic injection molding, this book was a good start for me. The issue is, you can take a feature (e.g. snaps) and write volumes on design and application - don't take one book/source to be the only reference.
The various resin suppliers also publish DFM literature that can be useful and worth reading.
Dupont Assembly Techniques -- more articles here
BASF on snaps -- more from BASF
And, as silly as it is... Occasionally protomold will publish a useful nugget of practical information.
>My challenge or I suppose my question would be what material I would use to manufacture something like that (like once I have a mold).
Material must be selected before the tool is made because the material properties drive the tool design (shrinkage rates, viscosity etc).
There are thousands of options for injection mouldable plastics so you'll need some requirements to narrow down your options.
Plastic Part Design for Injection Molding: An Introduction By Robert Malloy is a great intro to IM part design.
Check second hand book sites for cheaper used copies (Abebooks.com is good).
There are free design guide pdfs online (of varying quality...) which give a decent intro but are usually tens of pages so obviously don't have the detail a decent books will. The guides by Bayer and Dupont are the best imo.
Although it's not a course but I recommend picking up this book, Plastics Part Design for Injection Molding by Robert A. Malloy. Professor Malloy recently retired but he was the head of the Plastics Engineering at University of Massachusetts Lowell. The book is really great for design engineers like yourself. Buy it and you will not regret it.

First, let's rephrase your statement 'SpaceX showed significant cost savings during Falcon 9 development, compared to traditionally procured launchers' The distinction is important, especially since you don't have insight into SpaceX's accounts to back up that claim, but rather tertiary sources through the GAO.
Secondly, developing launchers and developing spacecraft art nothing alike. I'm almost a full stack launch vehicle engineer. I'd be so far out of my depth on a spacecraft development campaign, it'd be funny. SpaceX was able to develop Falcon 9 for so cheap because:

I'm probably a bit late here, but I had a spell for six months or so (more than a decade ago), when I was rather distracted by reading (putatively non-fiction) books about space colonization. So here's my late-night ranting summary of this research (links to some key references at the end of this post):
A strong argument can be made that the short- and long-term goals of colonizing space should NOT be to colonize other planets, but in between.
In the "short" term, this could help people on Earth solve certain specific resource scarcity problems (particularly with rare metals and energy production), but colonizing space (or other planets) is NOT a general solution to Earth's overpopulation, pollution, war/conflict, famine, disease, etc. The fuel costs of getting off the Earth are just too outrageous to ever lift a significant fraction of people into space. If anything, the probable isolation of space colonies (planetary or otherwise) could easily create all sorts of issues by themselves. Long-term, this would just be about expansion, spreading life out across the solar system for reasons already in this thread.
If you, erm, dig into the space colonization literature, a lot of the most compelling things have to do with building very large orbital space colonies that spin to simulate gravity, and then recovering natural resources from space, mostly solar power and mining asteroids to sustain and grow colonies and provide attractive merchandise to the Earth.
The classics of the genre (which is much larger than I expected) were written around the time of the space race and focused on bootstrapping self-sustaining orbital colonies, and importantly were built around technology and principles from that time period, not requiring huge leaps in technology (or remotely reasonable computing power). So now these things would (in principle) be more feasible today than, say, the 1970s. The basic notion is that it is far too expensive (and kind of pointless) to focus on colonizing planets. We would basically increase our costs massively, since we would constantly have to climb out of massive
gravity wells. So we should just live in space itself. This isn't saying that we couldn't settle worlds, but that would be a side-show to the main event.
The initial costs are outrageous (though not compared to colonizing Mars), and I personally have a hard time justifying any of it, when we have a hard time dealing with some basic-ass shit just in the US much less the world, but given some disposable income and solidarity, the people of Earth could do it. Should we? In my mind, outside Earth orbit, I'd focus on using robots, until we get our shit together (perhaps helped by robots bring from space the feedstocks for clean fusion plants).
The bootstrapping comes from mining and extremely excellent solar power (which are both much better in orbit than on a planet). The original idea of beaming energy to Earth via microwave radiation is perhaps a bit hare-brained, but maybe not completely. However, asteroid mining could be extremely lucrative, given self-sustaining orbital bases of operation. Mining on Mars or other non-Earth planets is absolutely NOT profitable in most cases, because the cost of lifting material into orbit would kill the margins. Space elevators are a possible futuristic thing for Mars, certainly compared to Earth (though see potential Mars-wide catastrophes a la Kim Stanley Robinson Mars trilogy).
The massive exception to planet-based mining is Helium-3. Helium-3 is extremely scarce on Earth, and mostly obtained as a byproduct of nuclear weapons manufacturing. But large amounts of the stuff could feed clean fusion plants (i.e. not producing radioactive waste). The bootstrap here is a bit destructive, since it involves strip mining the Moon (no elevator needed to save fuel during off-Moon transport, just a big rail gun). But it would be much better to dip robots into the gas giants to filter helium for helium-3 for this potentially outrageously lucrative source of income that could lead to a post energy scarcity world.
Many of the intensely researched books in this area are a bit needlessly provincial in their world view, offering a sort-of space suburbanite 1950's White Americana feel, but they are written by some serious scientists/engineers, and I think they have a lot to offer in the vein OP is seeking. An oddity that might define the genre is that they probably legitimately qualify as non-fiction, but frequently use the future tense, which is, well, unusual, and most of them kind of go off-the-rails at some point. Nevertheless, there are some pretty serious ideas in these classics and their ilk about how this could be done in a way that is really Earth-centered at the outset, where the whole point is to find a new untapped resource to exploit.
Okay, so as not to lose track of OP's main question, I'll stop.
Core reading list:
The original classic is Arthur C. Clarke's The Promise of Space, published in 1968. This sets the stage for the idea that terraforming is not the main event and the man that proposed the geosynchronous orbit covers some serious ground.
The CLASSIC classic is Gerard K. O'neill's The High Frontier, published in 1977. This is essential reading for the space colonization aficionado and forms the foundation of the "non-fiction" genre around the subject.
The mining classic w is Mining the Sky by John S. Lewis, published in 1997. This really lays out the mining thing, especially with respect to the shittiness of big gravity wells and how abundant supplies of helium-3 could be transformative.
I'll quit. There's so many more possible references that explore very proximate things, like how to insure rocket launches and way more far-out stuff, like how to minimize inbreeding on generation ships, but I think if I were to pick three things to read, those are them.
EDITS: for some typos and grammar that I saw.
The report card you're referring to says we should invest more in our infrastructure - it has nothing to do with our knowledge of how to build bridges or more complex structures. That is a matter of funding over technical ability. Yes, I do think we can build complex structures in space. Because we wouldn't have to deal with gravity, in many ways it would actually be easier. This is not a theory in the slightest.
You should read about Lewis One, Kalpana One, and the books The High Frontier and 2081, as well as Gerard O'Neill's Physics Today article - that last goes into a lot of math on how we would build one, and building one was technically possible even then. Our engineering ability is not the question - our political will and funding is.

The Elysium habitat is about 2 miles big. It is not possible to construct such a Standford torus habitat by exporting materials from Earth surface - the launch of this amount of material would have deleterious effects on the planetary atmosphere - exporting that much material burns off A LOT OF energy, assuming any permutation of current propulsion types.
The only way to construct these kinds of habitats would be by means of mining the moon and NEA asteroids. The time to implement these kinds of industrial infrastructures is (if we invest maximum effort as a planetary society) would be about 20-30 years, and after that we would be able to construct small "Island One" habitats, which are much smaller than these Stanford Torus rings.
Essentially, it would be possible to construct an ever increasing number of these space habitats the moment you have the first. That implies that the number of habitats you can construct would follow an exponential rate. Let's assume it would be possible to erect the first (small) habitat 50 years after humanity goes full force space industrialization. Ten years later we'd have a small habitat. Twenty years we'd have three of these habitats. Thirty years later we would have something like six. Forty years later we could easily have over ten. Then 20, 40, 100, 200, 400. Essentially by 2150 we should have not a single such habitat, but thousands.
Each with a few thousand people living on them.
There is enough asteroid material in the solar system to replicate several thousand earth surfaces from these asteroids. Following the above exponential growth curve it follows that by 2250 most humans would or could be living in space under conditions substantially better than the ones depicted in te movie Elysium.
Even better, the ability to produce energy by SBPS would follow the same trajectory.

This is all science fact. Nothing I have said is impossible with todays technologies'. In fact it was well possible with 1970s's technology and these designs were presented to the US senate in the mid 1970s.
But then something happened and some people in charge decided this was not the way they wanted humanity to develop.
You need physics, not math. I would suggest to borrow/buy a general mechanics book (Alonso-Finn, Tipler, etc.) and read some if you are serios writing about Hard SF. Then there are specific books about artificial stations/worlds; like this classic “The High Frontier: Human Colonies in Space”. Also, you need to take into account the Coriolis force if your station is too large. This wikipedia article is a good start.
As for the answer you were looking for: the acceleration is [angular velocity]^2 [radius], thus your problem is not exactly the radius but also the angular velocity. As you need a particular period of 34 hours the angular velocity is fixed to 2pi/(34 60 60) = [angular velocity]. Finally, you can find your radius from [your gravity]/[angular velocity]^2.
A mark's handbook will probably get you started --

Mechanical engineer, here. There is no substitute for actually building something, which it seems you're already doing. Outside of coursework and training, I would recommend the following resources:
FUNdaMENTALS of Design: You can download the PDF here. Tons of pictures and equations. This was the "course book" I used in undergrad @ MIT, and you can get it for free! Not really organized, per se, but one cool thing about it is that it's meant to be flipped through and printed double-sided. One side is always a birds-eye or holistic view, and the opposite side is always an in-depth and theoretical treatment of the topics. This is a great way to find out, "Wow! This exists, and here's what it's called!"
Mechanical Engineering Design: This is a pretty good primer on mechanical "stuff."
Mechanisms and Mechanical Devices Sourcebook: This is a great resource to keep handy. I look at this ALL the time, especially when I hit brick walls and need inspiration or fresh ideas.
Misumi: Pretty good place to get industrial-grade mechanical components... not sure about the prices for hobby-level stuff. They also have some good literature and tutorials here.
Hope it helps, and feel free to PM me if you have any questions.
Edit: primary != primer
I have this book and I love it

I second Bruhn, also going to throw Roark's out there.
Bad Science by Ben Goldacre, Demon Haunted World by Carl Sagan for general science.
Stuff by James Randi, Michael Shermer for general stuff about new age crap.
The Panic Virus by Seth Mnookin and Deadly Choices by Paul Offit on the Anti-Vaccination movement.
Damned Lies and Statistics by Joel Best and How to Lie with Statistics by Darrell Huff (Also see How to Lie with Maps by Mark Monomonier for a similar subject) for questioning stats and graphics used in the news.
Is there anything specifically you're interested in?
All the land is under the thumb of one government or another, so simply purchasing land will do you no good. The one possible exception is Somalia, but then you'll be just another warlord, and the guys already there have more practice than you. You'll need to create new land.
Start by donating to focusfusion.org. If it works out (and things are looking good so far) then in five years we have commercial small-scale non-radioactive fusion reactors producing power at 1/50 the price of coal. As a backup, invest in polywell fusion, which will be a bit slower to develop but still good. From there you can take two routes:
For an even more speculative project, fund experiments on the Woodward Effect, which, if Einstein and Mach were right, could reduce launch costs to almost nothing and get us to Mars in a couple days, and Saturn in a week.
Since you're proposing a massive land purchase, perhaps you have massive funds to do this sort of thing. You could get your libertarian nation without hassling with legacy governments, and incidentally, save the world.
If you don't have the massive funds yourself, start a foundation and get a big group of people together to do it.
The Millennial Project: Eight Easy Steps to Colonizing the Galaxy
Packing for Mars: The Curious Science of Life in the Void by
Mary Roach is quite good. It follows the history of the manned space program, and the challenges to overcome before we send a mission to Mars.
In interviews with Mary Roach they most likely did not. There isn't enough privacy (or room for privacy in the shuttle).
After reading the sample and some of the reviews, I went ahead and made a purchase. I also bought 'Pale Blue Dot' from the same author.
Would you recommend Space Chronicles: Facing the Final Frontier by Neil deGrasse Tyson?
Neil Degrasse Tyson addresses #8 (#10?) in his book Space Chronicles: Facing the Ultimate Frontier. He makes the point that truly cutting-edge exploration and the necessary technological advances it requires is far too risky of an enterprise to make it a sound business investment. However, those same advances go on to benefit private industry and society as a whole.
Edit: The second #8... Probably should be #10.

If you pm me I can give you a pdf copy of the older version.
Here's a good primer to the physics of the neural nets you'll be encountering in the wiring as well; required if you're going to be doing some logic-level debugging (which is pretty much all the time if you want to go beyond the usual Swedish teutonic - which is why you're here, right?)
There are ChemEs who work in beautiful locations (LA, SF, etc.) and there are ChemEs who work in bad locations (Midland, Maxbass, etc.)
 
I don't agree that ChemE is a dying degree nor are you limited to working in dirty industries in remote location (I have experienced both sides).
 
To the OP: Take an introductory chemical engineering class to get a feel for it.
 
Most introductory classes use this textbook.
 
https://www.amazon.com/Elementary-Principles-Chemical-Processes-Richard/dp/047168757X
The book I'd recommend is the textbook that most intro ChemE courses use: Elementary Principles of Chemical Processes, by Felder.
It's not too heavy on prerequisites (mostly just algebra, general chemistry). The problems you'll solve in the text are good examples of the type of thinking that ChEs use, and the author does a good job of explaining things. Also, some anecdotes from time to time.
Not sure if that's what you're looking for, but I can't really think of many non-textbook type examples for the same reason chemical engineers don't show up in films: it's not "Hollywood sexy."
I have two recommendations:
http://www.amazon.com/Differential-Equations-Scientists-Engineers-Mathematics/dp/048667620X/
This is an excellent survey that saved my bacon as a physics BS student transitioning to graduate PDE in math. The text is clear and divided into easily consumable lectures. It's also available for $10, a bargain.
http://www.amazon.com/Partial-Differential-Equations-Action-Universitext/dp/8847007518
This is the book I would recommend as a "second pass" through PDE. If you pursue the subject as a graduate student, this will give you information necessary as you transition to applying real analysis and basic functional analysis ideas to solving PDEs. It has a very holistic approach, but uses a lot of ideas and tools that I didn't see until graduate school. It's a great self-study (but definitely higher level than Farlow), and would be an excellent book to convince your graduate level PDE teacher to give a two semester course from(assuming they were of a more cooperative disposition).
Just get yourself a copy of this and celebrate with beer.
As another option, a relatively easy-to-read book is Farlow's book on PDEs for Scientists and Engineers. It breaks up a bunch of PDE topics (everything from the Heat Equation to perturbation methods) into short lessons using a relatively informal, non-rigorous approach. I'd highly recommend it for beginners and for those who'd like a quick overview of the applications of PDEs to areas in Physics/Engineering.
These aren't websites, but The Art of Electronics and its companion Learning the Art of Electronics are often referred to as learning resources, for good reason.
​
There are of course web sites that teach you electronics, but not on the level these two books, imho. If you don't want to buy books, then I'd recommend you to go watch bigclivedotcom and EEVblog, they have some great content. There are lots of other YT channels with similar content.
Also look for the student lab manual that accompanies the 3rd edition of AoE. This book makes AoE much more approachable. Be sure it's the 2016 edition.
Mathematical Methods for Physics and Engineering is an excellent book that covers most topics you will ever need for your undergrad degree.
Riley Hobson and Bence, also Riley Hobson and Bence and maybe Riley Hobson and Bence...
this book has been my bible for the last few years and contains every single piece of maths I have needed for the last few years and, from what I've heard from those further into the course, will last a long time.
I don't know what's going on in this thread. One poster is giving you useless advice about just "trying hard and keeping at it" (as if that's at the root of this issue), one poster saw an opportunity to vent about his personal frustrations and project them onto you (your supervisors are tools, they only care about promotions!), and yet another one decided to pitch in with a useless comment about some random exam they have tomorrow.
So let me give you a level-headed comment that might actually prove useful to you.
First off, you took zero math courses during your undergrad. There's your first problem. Geophysics is what happens when the concept of an inverse problem takes on the shape of an academic discipline. It's a very mathematical and physical subject.
Ideally, you should have completed all of single- and multi-variable calculus. You should have completed a course in linear algebra. You should have completed a course on differential equations (both ordinary and partial), and you should have a solid "signals and systems" course under your belt. Additionally, it'd be very useful if you had a (mathematically-oriented) course on probability and statistics, though this isn't strictly necessary at all, the preceding courses should suffice for 95% of the stuff you need to know.
That about concludes the mathematical side of things. Now let's be real. I just listed about 2 years worth of mathematical coursework, split over at least 5 quarter or semester courses. You're not going to be able to catch up with that.
My solution: get a "Mathematical Methods for Physics/Engineering"-style textbook. There's a few on the market, such as Boas' famous book. That one doesn't start at your current level though, so I don't recommend purchasing it.
The one book that fits the bill for you, and that I'd strongly recommend you purchase is Riley, Hobson and Bence's "Mathematical Methods for Physics and Engineering", Cambridge University Press. Get the latest edition (the 3rd). If you're in the US, the book will set you back about $60 on Amazon, or $50 on Bookdepository. Don't buy the cheap, crappy international edition. This book is massive (1300+ pages). Skip the chapters on quantum operators, group theory and representation theory. Work through the rest. Alternatively, an equally good book, though more concise, is "Mathematical Methods for Physics and Engineering", the 2nd edition by Weltner, Weber and other authors (it's a Springer book). This one really builds you up from scratch, which is great for a beginner like yourself, but hardly has any exercises. If you're really, really short on time, get Weltner et al. If you think you can put in the work and time, definitely go for the Riley/Hobson/Bence book. Also, definitely think about getting a Schaum Outline on Precalculus to quickly get up to speed on some fundamentals (a physical copy will only set you back $14 on Amazon). Seriously, this might prove very useful to you. Don't get the e-book editions,though. They're badly formatted.
That's at least 1000 pages of dense mathematics. If you're confident you're determined enough to get through it, that should be a good stepping stone to start from.
Next up is the physics. Get a University Physics textbook. I'm a big fan of Young and Freedman's University Physics, though you could consider Manfield's Understanding Physics as well as it might be more accessible to you. Study through the sections on mechanics (statics, dynamics, mechanics of materials), electromagnetism and waves (especially the waves section).
At this point you should really consider getting up to speed on signals and systems. Especially seeing as you're working with stuff like SEISAN (which is basically applied signals & systems theory). The one book that stands out, big time, is Lathi's "Linear Systems and Signals, 3rd edition". This text is amazing for self-study. It's incredibly expensive though. If you can't spare the money, there's a pretty cool little book that's freely available and unlicensed, written by prof. Chi-Tsong Chen from Stony Brooks. You will find it here, titled Signals & Systems: a Fresh Look. It even has a brief section on seismometers.
From here on out, ask your supervisors etc what books they'd suggest that specifically deal with geophysics/seismic stuff. I could recommend you a few if you're still interested after reading this daunting wall of text.
Let me know!
The Case for Mars lays out a long term plan for terraforming Mars. Arguments can (and have) been made on if it will work, but someone has a plan.
And there has been a time in the past when argumentative, incorrectly informed, conservative douches were right although it doesn't mean that we aren't all screwed this time and it really is the doom of all life.
Check out some documentaries, it will give you stuff to think about. Vanishing of the Bees, Queen of the Sun...I believe both of those are on Netflix.
One of my favorites is Nova's Tales from the Hive...check on YouTube, there was a high-res version in three 20-ish minute parts. These crazy film makers put surgical cameras on bees! It gives you a great perspective of things from the bees' POV.
Edit...Here are links to the best version!

Part three: http://youtu.be/fM_fcVCRKew
Another great book, although very scientific, is the Beekeeper's Handbook (http://www.amazon.com/The-Beekeepers-Handbook-Diana-Sammataro/dp/0801476941).
I've been meaning to read Honeybee Democracy but haven't gotten around to it. In fact, I'm going to get on Amazon and see if there is a Kindle version right now. (Edit: yay, there is! There wasn't the last time I looked: http://www.amazon.com/Honeybee-Democracy-Thomas-D-Seeley-ebook/dp/B0046A9M68/ref=sr_1_1?s=books&ie=UTF8&qid=1405486484&sr=1-1&keywords=Honeybee+democracy)
I'm also going to come back and edit with links...edited to add, I did 😊
I'm new - I don't have my bees yet, they're on order - but I've been studying like mad. I'm an IT consultant who swings between tons of typewritten and moderate amounts of handwritten notes, and that's likely to translate into my beekeeping life.
I've written all of one beekeeping post so far: The waiting is the hardest part (Beekeeping part 1), and it's just a status update and a bare few notes.
BUT I'm underlining my copy of The Beekeeper's Handbook like crazy, and I'll probably go back and make notes out of that!
Some of the books on my shelf:
The Beekeeper' Bible, How to Keep Bees and Sell Honey, Beekeeping for Dummies, Natural Beekeeping, The Backyard Beekeeper, The Beekeeper's Handbook.
I think the best bang for your buck, and certainly the one that helped me most, is The Beekeeper's Handbook, 4th Edition. It includes the most recent available data on pests and diseases (although I think I noticed that microscopic images of 2 diseases were reversed... I have to check that again). It discusses, in a really straightforward, textbook-like style, castes and life cycles of bees and their pests, 4-season best practices for management, all the way up to honey extraction and marketing. It mainly deals with Langstroth hives, which is typical. Other styles are introduced, however, and people who are interested can find additional resources.
Natural Beekeeping is a good complement, as it deals strictly with organic beekeeping. Even if you can't go totally organic (I live near non-organic orchards, so it's a joke for me), it's wise to know what options exist so you can do what you can.
Beekeeper's Bible has some great info about early beekeeping and bee symbolism, along with some recipes for foods and salves - but most of that is pretty easily researched online.
I hate anything "For Dummies", How to Keep Bees is pretty outdated, Backyard has good info but feels like it's shilling for a certain supplier and I don't think the math works out for using 8-frame hives instead of 10-frame.
tl;dr This: [http://www.amazon.com/The-Beekeepers-Handbook-Fourth-Edition/dp/0801476941/ref=sr_1_1?ie=UTF8&qid=1334286109&sr=8-1]
You can look for an old copy of Mark's Handbook. This is a handy guide to pretty much everything to do with mechanical engineering.

Investigate your local community colleges. It's becoming more and more common for them to have prototyping labs (with things like 3D printers and general machine shop resources) that are available (essentially) to the general public.
I use this in my Electrical and computer engineering course in college...
Practical Electronics For Inventors
We are really only going over theory and some diode/transistors. But it was cheap and it looks like an excellent book that I will keep in my own personal library
and 20 bucks aint too shabby
Practical Electronics for Inventors is an amazing book which covers the basics of essentially every aspect of electronics a beginner would need to know. Seems to have had a problem with poor editing but it's cheap (under $30) and still far better than anything else out there.
The Art of Electronics is twenty years old and is still pretty much the standard reference for practical electrical engineering topics. Some sections show their age but still incredibly useful. A new edition is supposed to be coming out eventually.
for a person with a visual mind I would suggest you start with [practical electronics for inventors] (http://www.amazon.com/Practical-Electronics-Inventors-2-E/dp/0071452818/ref=sr_1_2?ie=UTF8&qid=1373135646&sr=8-2&keywords=practical+electronics+for+inventors) and an arduino (a specific microcontroller with a lot of helpful tutorials) to [cut your teeth on] (http://makezine.com/arduino/). Once you do a couple projects maybe interface with a couple chips you'll be on your way to creating whatever electronics you want.
I've worked with some designers who had books like these:
Mechanisms and Mechanical Devices
[507 Mechanical Movements and Designs]
(https://www.amazon.com/507-Mechanical-Movements-Mechanisms-Devices/dp/0486443604/ref=sr_1_2?ie=UTF8&qid=1484237480&sr=8-2&keywords=mechanisms)
Honestly though, these books might be good bathroom reading, but design comes down to experience. The more problems you solve, and the more things you make, the better your designs will be.
Having been a design engineer for a while now, the absolute best advice I can give you is to talk to the other people who will be using the stuff you design. Starting out, your designs aren't going to be the most elegant. Focus on getting something that is functional.
Then, talk to the machinist who is making the parts. He'll have some advice on what features are difficult to machine, or some features you could include that make your parts easier to manufacture, such as adding a flat surface to use as a datum for machining setups, or "bonus holes" that can be used for lifting or securing the parts on the machine. Maybe if you loosen some tolerances, he can order a piece of mill standard pipe instead of having to hog out a huge piece of round stock. Maybe if you tweak the geometry just a little bit, the part can be made on a manual machine instead of having to wait for the 5 axis CNC to open up.
Talk to the techs who have to operate or maintain the machines. What makes their jobs difficult? They'll know best what parts are hard to access, or which tightly packed assemblies don't have clearances to fit tools in, or what's constantly breaking and needs to be replaced often. They'll show you the "custom made tools" that they improvise so that they can actually work with your equipment.
Talk to the people in procurement, or your suppliers and vendors. Is there cheaper hardware you could use? Maybe switching materials would make it easier to source raw stock. Maybe there's an off-the-shelf coupling you could use instead of machining a custom bracket to join two components. These guys work with lots of other people in your industry, and will gladly share "how the other guy did it".
Well the whole field of what you are delving into is categorized as Kinematics and Dynamics, which is enormous.
​
There are very many types of mechanical devices designed by various people throughout the world which can accomplish what you need.
​
Many of them could be applied to your system and only you can fully determine what the "best" one is, depending on your requirements.
​
This is a nice book to look through for ideas:
​
https://www.amazon.com/Mechanisms-Mechanical-Devices-Sourcebook-5th/dp/0071704426/ref=sr_1_1?crid=2CRBTTO3RT6RC&keywords=mechanisms+and+mechanical+devices+sourcebook&qid=1557683532&s=gateway&sprefix=mechanisms+and+mechanical+%2Caps%2C143&sr=8-1
​
As far as calculating things, it's extremely difficult without some knowledge of math and a little experience in applying said math to your design. This is pretty hard to do without formal education of at least the basics of these fields.
​
For example, do you know how to isolate the elements of your design and draw a free body diagram of each of them, without making logical errors (which are pretty easy to do by the way).
​
This is a basic engineering design method you need to use to perform calculations on your proposed designs. I don't think it could be well explained through a forum post. It would go much faster by having somebody help you out in person, or if you can do this, pick up an engineering book and read the relevant sections carefully so you understand them enough to apply them. This tool is initially learned in the fields of Statics, so you'd need a Statics book first. Then you'd need a Kinematics and Dynamics book to determine forces due to acceleration.
​
Looking briefly at your design, my first impression is that it can work. However, make sure that the linkage attached to the servo and the push rod and control horn never fully go parallel to each other. If that happens, you have no guarantee that the mechanism will return to its original proper position.
​
I can explain with a very disturbing analogy. Imagine your elbow can rotate 180 degrees so you can bend your arm backward fully, and for our sake, lets also imagine that this is totally normal and is not damaging.
​
Now imagine you are holding your arm straight against a wall so that the two linkages of your arm, the (1) forearm part and (2) bicep part are in alignment.
​
When you push against the wall, will your arm bend one way, or the other way? The arm has three options, depending on minute and uncontrollable differences: (1) If the force is perfectly horizontal your arm will not move at all and will continue to push against the wall (2) the forearm moves "up" and bends as normal and (3) the forearm moves "down" and bends backwards.
​
The same will happen in linkages if the they all line up. Since we want the linkage to always move the way we want it to move, we have to prevent this special position form occurring.
​
That's a common problem that people who have never designed linkages easily run into.
I use this one a lot for inspiration when I need to design new mechanisms.
https://www.amazon.com/Mechanisms-Mechanical-Devices-Sourcebook-5th/dp/0071704426
Mechanisms and Mechanical Devices Sourcebook might be nice.
Its like a museum of mechanisms. I like the 2nd Edition cover for a "coffee table book".
I have the Mechanisms and Mechanical Devices Sourcebook, Amazon. I have the fourth edition, but the link is the fifth. It's a good book showing how to design them and has a ton of examples.
For a stress guy, in addition to the previously mentioned Bruhn, All three of Niu's books are worthwhile.
as well as:
Roark's
Peterson's
Have a look at/into:
Good suggestion regarding #1 and #2, especially #1. I use my copy of the Machinery's Handbook regularly as a lookup reference; it's invaluable.
I'd add to the list Roark's Formulas for Stress and Strain. If you want to have either it as a reference and/or you don't know/don't trust your math, this gives you the formula for pretty much anything you need, mechanically. I use this habitually when designing anything beyond the trivial to double check my numbers. It has generalized/normalized formulas for stress, strain, deflection, vibration ,etc for beams, plates, shells, and the like. Oh, and the newer versions have the formula modifiers for solving in both metric and imperial units. If you are doing mechanical design work, this has a place next the the Machinery's Handbook.
Cheers,
The stock answers are Roark's if it was full of equations, or Shigley's if it was full of diagrams.
Maybe Machinery Handbook, but it doesn't sound like it.
I lost my 6th version and recently bought the 8th. I don't know where you're shopping, but it's under $100 on Amazon. Even the list price is only $135. Are you looking at the gold plated collectors edition?
Some books I can recommend for map nerds: Strange Maps: An Atlas of Cartographic Curiosities, How to Lie With Maps, and a related book that's a bit more useful for data visualization - Visualize This: The FlowingData Guide to Design, Visualization, and Statistics.
The typographic maps from Axis Maps are pretty awesome and there's all kinds of map-related stuff on Etsy.
You've already had some good suggestions, which I'd suggest following. I have a BA in geography and even after school found these interesting reads.
Cultural and Historical Geography
Eratosthenes' "Geography"
The World of Gerard Mercator: The Mapmaker Who Revolutionized Geography
Guns, Germs, and Steel: The Fates of Human Societies
Race And Culture: A World View
Technical, GIS, Cartography
How to Lie with Maps
Thinking About GIS: Geographic Information System Planning for Managers
An Introduction to Geographical Information Systems
I know most of these won't be of much use with a BS degree, but gives you a good foundation for thinking geographically. For the more science aspects; a good understanding of physics, chemistry, and to a lesser extent biology, will really give you a leg up when starting out.
Hot to lie with maps.
Ich finde übrigens Goode homolosine projection recht spannend.
The continents are all connected right now. Every map you see is a lie.
Maps are all lies.
there are other ways too http://www.amazon.com/How-Lie-Maps-2nd-Edition/dp/0226534219
(No this doesn't involve sleeping with maps)
The book The Millenial Project: Colonizing the Galaxy in Eight Easy Steps talks about a suit that is made from a material similar to lycra.
The anthology Armored has a bunch of stories about armored suits, and possible variations from those.
Imagine the suits to vary depending on mission and MOS. Infantry, navigation, logistics, engineering etc.
If we get all fancy, lets imagine that they are all made of smart matter, or quantum dots, or some sort of mix that allows high variability, adaptation, low weight, and lots of energy available to do the sort of stuff our hero would need doing.
Remember the utility fog in "Quantum Thief"? I imagine that these new suits would be pretty much like that, fast reaction times, not in the way unless needed, light, flexible and extremely expensive. Also, failure ought to be benign as to protect until rescued.
Titan is Saturn's moon, and yes, its ice volcanoes are one of the coolest tectonic events in our solar system.
As far as we know, there aren't any solid diamonds at the center of anything. Diamonds are much lighter than metals and other heavy elements, and would not sink to the center of a planetoid. Perhaps some pre-supernova planets, but those wouldn't have any of the heavy elements necessary to support life. Once we are traveling between stars, it's the biogenetic substances--like water and unrefined carbon--that will be the most valuable and useful to mine. With space colonization it becomes a matter of sustaining the continuing expansion of life, not space ships, that is most important. Fortunately there is a lot of ice on moons like Europa, and plenty of other valuable minerals and metals in the asteroid belt. There has always been a frontier: cyberspace has come and gone as the lastest frontier: next comes a space station! Once we've colonized out to the asteroid belt, perhaps interplanetary cyberspace will become still another metaphysical frontier to be explored?
I'm not sure where I was going with all of that. It trips me out.
Have you read The Millennial Project: Colonizing the Galaxy in Eight Easy Steps? I think it would be right in line with your interests. It is the most mind-blowing book I have ever read, making NASA look like a bunch of idiots and literally turning galactic colonization into a rather common-sensical eight easy steps, beautiful in their simplicity. If you have a scientific mind, this book will make you trip hard balls of intellectual goodness. There's even a website carrying on the book's legacy by updating the material as new scientific insights arise.
This picture is from the book The Millenial Project: Colonizing the Galaxy in Eight Easy Steps by Marshall T. Savage. Some of the calculations are wrong, but it is an interesting read. But you don't have to take my word for it.
Yes, Mary Roach actually wrote a book called [Packing For Mars] (http://www.amazon.com/Packing-Mars-Curious-Science-Life/dp/0393068471) where she interviewed a few astronauts and it turns out it's actually very possible. Let's say you are working on something and not really paying attention and your body will kind of reassess where "down" is. So when you turn around and don't see yourself oriented the way you thought you were it makes you feel like you are up-sidedown.
A book I'm reading. http://www.amazon.com/Packing-Mars-Curious-Science-Life/dp/0393068471
Full of fascinating tidbits.
Read Packing for Mars by Mary Roach. She does a great job explaining the difficulty of surviving space flight, including the lessons learned from the Challenger explosion.
Radiation is the largest concern. The Earth's magnetic field shielded the Apollo astronauts from the worst of the solar radiation, but in between the Earth and Mars no such protection exists. And interesting book on the theory behind space travel and how hard it can be to put it into practice is Packing for Mars: The Curious Science of Life in the Void. You should check it out.
http://www.amazon.com/Packing-Mars-Curious-Science-Life/dp/0393068471
I haven't read too many that would fit the bill, but the first ones that come to mind are:
If anything else comes to mind, I'll make sure to post it.
Indeed, but it's actually from Neil deGrasse Tyson's new book: Space Chronicles: Facing the Ultimate Frontier. It's really good, but I'm only a quarter of the way through.
A physics degree is more than adequate for this kind of work. Your day to day would likely consist of properties testing (mechanical properties like tensile strength and hardness most likely, but also perhaps corrosion, chemistry, creep, etc, depending on industry), microstructural analysis, and failure analysis. With a degree in physics you should be able to pick up an undergrad material science text like Callister and fill in the more applied science gaps in your education.
There are a variety of introductory materials science books. The one by Callister is probably the most widely used, at least in the U.S., but personally I prefer Ashby and Jones.
The University of Cambridge also has a nice set of tutorials online, here.
Stuff Matters is a easy read without all of the calculations, so it's a really go way to learn theory without getting bogged down with math - it's also on Bill Gates book list. Also, this is the only textbook I've ever read cover to cover - my professor was a nut, but we learned a shitload. Good luck, OP!
Maybe you could use a basic crystal structure like the one pictured on the cover of Callister? (https://www.amazon.com/Materials-Science-Engineering-Introduction-8th/dp/0470419970) Its the most often used Intro MSE course textbook.
Callister is pretty common http://www.amazon.com/gp/aw/d/0470419970?pc_redir=1408455443&robot_redir=1
For Statistical physics I would second the recommendation of Pathria. Huang is also good.
For electromagnetism the standard is Jackson. I think it is pedagogically terrible, but I was able to slowly make my way through it. I don't know of a better alternative, and once you get the hang of it the book is a great reference. The problems in this book border from insane to impossible.
So that's the basics. It's up to you where to go from there. If you do decide to learn QFT or GR, my recommendations are Itzykson and Carroll respectively.
Good luck to you!
Can you get through a paywall?
Here is a tutorial on optical antennas. Pretty nice, if I do say so myself ;)
Jackson's electrodynamics has a chapter on the dielectric response of metals. Chapter 7, section 5. "Frequency dispersion characteristics of dielectrics, conductors, and plasmas."
Novotny's nano optics book has a brief review of dielectric response, and talks a lot about the antenna analogy.
Third edition?
At least, that's what google says.
Surprised no one has mentioned Classical Electrodynamics by Jackson.
For practice with your problems, Schaums' guide are the best. If you feel like a badass
I was going to do something similar but the second picture was going to be this
They may have changed now, but chemcical process principles probably still uses http://www.amazon.com/Elementary-Principles-Chemical-Processes-Richard/dp/047168757X
the thermo book is very professor dependent.
this was another one, but I think it was mass transfer http://www.amazon.com/Transport-Processes-Separation-Principles-Operations/dp/013101367X/ref=sr_1_45?s=books&ie=UTF8&qid=1398311420&sr=1-45&keywords=chemical+engineering+fluid+mechanics
the first book I linked will definitely give you the best head start, spending any time with any others would probably be a waste of time. I can find my fluid dynamics book at work tomorrow, but I wouldnt get too worried about it, to be honest.
This book ?
Make sure you have a good foundation in mathematics. If you want to get started for Cheme - definitely get yourself a book on material and energy balances. This is widely heralded as the "bible" and will give you good introductino to many cheme concepts.
​

I have these two text books on PDE's
https://www.amazon.com/Partial-Differential-Equations-Bleecker-University/dp/1571460365
https://www.amazon.com/Differential-Equations-Scientists-Engineers-Mathematics/dp/048667620X/
The second book is more of a stereotypical cook-book math text. Idk if that's what you're looking for or not but it's inexpensive anyways and does a good job for its purpose.
The first textbook is very well done and is for beginners. However right now it's on the expensive side but when I bought it it was only 30 dollars. So if you wait a little bit the price may drop.
Also one last comment about the first textbook is that the order of the topics is abnormal. The first chapter does a summary of ODE which makes sense. However the first PDE material in the book covers first order PDE's which in my experience is not normal. Usually when people first learn PDE they learn about the heat and wave equations which are second-order PDE's. Idk if you care but I thought I'd just comment on that.
Check out Partial Differential Equations for Scientists and Engineers by Stanley Farlow. I've recommended it to another engineer in the past and he seemed to find it useful.
I used this book for my PDE class. It's meant to be supplemented with notes, but it does a decent job explaining material on it's own. That and it's super cheap for a math book.
Note that it has several errors in the answer key.
2nd the recommendation for Art of Electronics. I just watched an interview with one of the authors by Lady Ada. He was building things for his own lab and started a course for people who just wanted to be able to build circuits without becoming an EE. The companion book, Learning the Art of Electronics is completely hands-on. A practical course in analog and digital circuit building in a book.
OK, you seem like you are trying to learn, and are asking questions, that is a good thing, and even if someone cringes at your terms, that's OK, you have gotten some good links for the terms and how to use them. Don't be put off.
Now I am going to recommend you see if you can get The Art of Electronics 3rd ed and Learning The Art of Electronics, get the ones with the gold covers. They are expensive, but you will learn huge amounts by working through the Learning book. When I was teaching college labs, I would recommend students get these books (2nd ed at the time). You can find all this information online, and you can learn it that way, but these books are excellent and well worth the cost if you can pull it together.
I couldn't find the student edition for the 3rd now that you mention it, maybe it's on the way?
I did find a lab copy though https://www.amazon.co.uk/Learning-Art-Electronics-Hands-Course/dp/0521177235/ref=pd_bxgy_14_img_2?_encoding=UTF8&psc=1&refRID=GQTJS7PC2N34TFHP7PSQ
I've found Riley, Hobson and Bence and Boas to be really good applied textbooks. The Bence is more of an introduction and the Boas goes more in-depth. If your morals are less than scrupulous then you can easily find a pdf of both online for free
Riley Hobson and Bence similarly has intro chapters on mostly all of that.
Universities tend to accommodate not having dedicated the summer before first year to preparation: don't worry. They're not going to drop you in at the deep end and watch you struggle.
Being good with maths will never hurt in a physics degree, though. If you're desperate to do something, in your position I'd skim parts of the PH300 course in a book like RHB if you have one available. I wouldn't buy a copy just for that, personally, but your mileage my vary.
If computing is a large part of the course and you've never programmed before, another option would be to get ahead on that. I've never dealt with FORTRAN but a quick Google pointed out a lot of tutorials that might help.
Beyond that I'm not sure what to say: unless something else on (or off) the course really stands out to you, I'd peek at the maths and/or programming.
I feel the need to plug Mathematical Methods for Physics and Engineering by Riley, Hobson, and Bence. It covers a vast range of everything you're going to need with good examples.
you might want to look into books in the category of "math methods for physics". This would help you learn/review the math you need for physics, with the mindset of understanding it from a physical perspective. I've heard Mathematical Methods for Physics and Engineering by Riley, Hobson, and Bence is good, though I haven't personally read it.
Try Mathematical Methods for Physics and Engineering: A Comprehensive Guide. There is also a neat student's solutions manual available. It has all of the material you will need, although problem difficulty is not really its strong point.
A bit longer, but all are solid suggestions, and although I could add two dozen more, I'm sure others will take up the cause.

You should read The Case For Mars next.

I did an ethics report on terraforming using this book:
The Case For Mars by Robert Zubrin
Some of the detail went a little over me, but his research makes it sound very possible.
http://www.thebeeyard.org/ebooks/ has several free books including the penn st one that was mentioned.
i have this one:
http://www.amazon.com/The-Beekeepers-Handbook-Diana-Sammataro/dp/0801476941/ref=sr_1_4?ie=UTF8&qid=1395340884&sr=8-4&keywords=beekeeping
Seems to be very detailed but not to the point that it is hard to read/understand.
Probably want to wait until spring for the bees. In the meantime, do some reading. This is a pretty good book for beekeeping in general. http://www.amazon.com/Beekeepers-Handbook-Fourth-Diana-Sammataro/dp/0801476941
As a noob, I've been reading and acquiring a lot of beekeeping books lately. Here are my thoughts:
"Homegrown Honey Bees" by Alethea Morrison is a nice introductory book that is loaded with photos. It's definitely a gentle intro book more than a reference book.
I really love "The Complete Idiot's Guide to Beekeeping" by Dean Stiglitz and Laurie Herboldsheimer. It covers all the basics and teaches a treatment-free approach. I was put off by the Beekeeping for Dummies book, which repeatedly recommends prophylactic use of chemical treatments.
After that I'd recommend a good reference book that has hive management diagrams, such as "The Beekeeper's Handbook" by Diana Sammataro and Alphonse Avitabile.
If you're interested in top-bar hives, I would get "Top-Bar Beekeeping: Organic Practices for Honeybee Health" by Les Crowder and Heather Harrell, and "The Thinking Beekeeper: A Guide to Natural Beekeeping in Top Bar Hives" by Christy Hemenway. Backyardhive.com has a great DVD on top-bar hive management.
If you want to geek out on beekeeping history, "The Archaeology of Beekeeping" by Eva Crane is legendary. It's sadly out of print and very expensive to buy. I found it at the library.
I would always recommend people start with 'The Compleat Meadmaker, by Ken Schramm'. This has been the meadmaking bible for a very long time. You can find supplementary information about staggered nutrient additions, pH buffering compounds, new sanitizers, etc online in various articles and forum sites. Of course, understanding your ingredients can also be very good for any brewer, and water is a huge ingredient. So besides the other element series book 'Yeast' by Christ White and Jamil Zainasheff I highly recommend 'Water' by John Palmer and Colin Kaminski. For those of us making mead in Ferndale, our water is a very key ingredient which comes to us from an underground aquifer treated by the city of Ferndale, and is of very high quality (even compared with the high quality water from the City of Detroit). Understanding honey is a huge area of study. There are many classic textbooks on honey and honey-hunting by Eva Crane that are considered primary sources (but these can be prohibitively expensive for most mazers, and honestly, Ken's book does an awesome job of summarizing her contributions, as well as other historical information about meadmaking, honey, etc). I feel a basic understanding of beekeeping can be highly instructive for meadmakers, and so I recommend that you get your hands on some beginner beekeeping books, e.g. 'Beesentials' by L.J. Connor and Robert Muir and/or the 'Beekeeper's Handbook'. A solid background in wine or beer-making doesn't hurt, either, and there are multitudes of books I can recommend to you on the subject of beer specifically (this is my homebrewing background). My two absolute must-haves for beer brewing are 'Designing Great Beers' by Ray Daniels and 'Brewing Classic Styles' by John Palmer and Jamil Zainasheff. Learning to brew beer can help you if you decide you want to try your hand at braggots.
remember, in lots of ways it's an art. there's a science to it too, but also an art. Get this book, it's really good: http://www.amazon.com/The-Beekeepers-Handbook-Fourth-Edition/dp/0801476941/ref=sr_1_2?ie=UTF8&qid=1345733249&sr=8-2&keywords=beekeeping
I don't think there's a consensus on the "best" book. I'm reading The Beekeeper's Handbook at the moment, and it's very good.
Natural Beekeeping is also quite good, if you want to try a more natural approach.
When I got back into beekeeping, a professional beekeeper insisted I read The Beekeeper's Handbook by Sammataro and Avitabile (https://www.amazon.com/Beekeepers-Handbook-Diana-Sammataro/dp/0801476941). It's an excellent, no nonsense textbook for keeping bees, and one that I now recommend to people that need a resource. Edit: hyperlink
Thank you! In Pennsylvania last winter there was roughly a 50% die off for hobbyists, so I figured I’d start with 1 hive to focus on and learn as much as I can from and hope for the best. I was ecstatic to find they did well.
You can do it! You just have to take the leap. Find a location, buy materials for 2 supers, buy your necessities, buy your bees, and, most importantly, buy a good bee book (I highly recommend The Beekeeper’s Handbook by Diana Sammataro) and start learning as much as you can as soon as possible. My father-in-law has been farming for almost 2 decades, and he jokingly commented last summer that I know more about bees after a few months than he knows about cows after X number of years. It was funny and a compliment, but you need to know bee behavior and be able to recognize what this buzzing super organism of thousands of bees is trying to tell you.
Just do it! Get started! It’s a highly rewarding hobby, and the tangible fruits of your labors are delicious haha.
Oh, and never let your smoker go out when the bees are starting to get pissy. Just trust me on that one.
There is also a very good book about it by George Dyson who is Freeman Dyson's son.
https://www.amazon.com/Project-Orion-Story-Atomic-Spaceship/dp/0805059857
It is actually a plausible way to travel to another Star quickly.
The Case for Mars is a good plan for how to settle Mars.
Project Orion by George Dyson is about the nuclear rocket program.
He's a neat guy. I really enjoyed Project Orion.
Not sure what to say as words of wisdom, except that you should get a copy of SMAD III if you're serious about making this project work.
The JC2Sat mission was supposed to be about a year, though the satellites should remain functional in orbit for years afterwards.
I don't have any ideas for a science project to include on the reddit satellite, just keep in mind that that space-certified equipment is outrageously expensive so you might just want to do something simple (like Sputnik) for a first shot at space.
There are literally hundreds of companies which specialize in all sorts of space-certified parts, with most of the big ones being American firms. If you expect participation of non-Americans with any of the hardware acquisition/assembly/etc, you'll probably run into ITAR restrictions at some point. For all the good that comes with international collaboration on space projects, ITAR pretty much negates it all. You wouldn't believe the hoops that non-American persons and companies have to jump through in order to buy something as simple as a space-certified hinge from an American firm...
There are several courses that ARO (usually) has, but ME exclusive program doesn't, such as Gas Dynamics, Low/High Speed Aerodynamics, Orbital Mechanics, Aircraft Stability, and Jet Propulsion. I based this statement from the school (CalPoly Pomona) that I went to. YMMV.
Book recommendations:
Aerospace is broad subject, you haven't specified whether you're interested in structures, aerodynamics, flight mechanics, or propulsion. I gave you a broad list of selection to reflect that, although I assume you are more inclined toward Astronautics (Space) part of Aerospace instead of Aeronautics (Air); hence you posted your question in /r/space.
its so much of a GODDAMN shame that these were never made, could have been, but wasnt.

For the downlink, sounds like you need a copy of SMAD. I'm sure you can find a free copy somewhere, but here's a link. http://www.amazon.com/Mission-Analysis-Design-Technology-Library/dp/1881883108
Specifically, it discusses the link budget equation in great detail. A necessary estimate of the type of power/antenna/frequency/datarate configuration you'll need. https://en.wikipedia.org/wiki/Link_budget#Equation
That said, the old team I was a part of used a UHF radio at ~700 MHz for our simple 9600 bps beaconing system. For one spacecraft, that was our only way of downlinking pictures, and yes, it tooks quite a few passes to get a full-res image. Compression sure helps.
For higher datarates, people typically move to an S-Band radio, which we did for subsequent cubesats. As a general rule, higher frequency means you can shove more data into the transmission. However, keep in mind your frequency's interaction with the atmosphere.
That said, I'm not an EE, I just worked with a bunch of 'em. :D

"Our plan was to send [manned] ships to Mars and Venus at a fraction of the cost of the Apollo program".
There would have been 150 people in a project Orion ship.
If we had utilised this technology we would have colonised Mars and the Moon by 1980.

Though it isn't a toroid or a bernal sphere like O'Neill's designs, my station, Island One, is the Kerbals first home in space. It is the start of their progress in ensuring thriving continuation of their race, and bringing the benefits of space industry to Kerbal.
Future plans for my rebuild in .21 include a fuel depot, kethane refinery, vehicles for Mun/Island One transfer with kethane, and way less parts. All the batteries on the power module and monopropellant tanks on the housing module are killing me!

Fly Me to the Moon, about non standard spacecraft trajectories has been sitting on my shelf, think thats gonna be the next book I read.
Mary Roach writes great nonfiction, but it tends to be more biology/anthropology.
Project Orion, a book about proposed nuclear powered space craft was excellent as well.
Lunar Base Handbook is more just a collection of papers, but its fascinating.
Have you read George Dyson's book, Project Orion? They were serious. From what I read there, they demonstrated some of the important functions of making it work. Including having the blast pusher plate surviving the nuke blast. I believe it had become an engineering problem and no longer a "will it work case".
IIRC The High Frontier: Human Colonies in Space, O'Neil (Bezos' professor cited in the article) sustained that pollution wouldn't ever be a problem in space because any undesired substance would be simply vented out of the habitat and solar wind would disperse it through hundreds of millions of miles of vacuum, all the way to insterstellar space. Like what happens in a comet tail. It was indeed one of his points in advocating that space was far better for an industrial civilization than a planetary surface like Earth's, where all shit that we produce innevitably accumulates.
Of course, in the far future, with human population on the trillions and scattered all over the Solar System in those space cities, crunching asteroids, small moons and eventually dwarf planets all the time for more resources, I suspect that there would be too much exhausts and the Sun seen from far away would start to look vaguely like a planetary nebula. In fact, I would love to see some SETI project exploring the possibility that some of the planetary nebulas are indeed artificial byproducts of civilizations that scaped the great filter of staying in their home planets for too long and running out of resources.
As others have pointed out, it won't work in space. But that doesn't mean they hadn't considered nuclear engines in space. Project Orion was a concept where atomic bomb explosions would be used to propel a spacecraft at incredible speeds. Famed physicist Freeman Dyson was a co-leader of the project. His son, George Dyson (a friend of mine) wrote a fascinating book about it called Project Orion: The True Story of the Atomic Spaceship.
Some crazy shit, man.
I thought it was around 20% c from the book for the Orion Project max speed. Did you read the book?
http://www.amazon.com/Project-Orion-Story-Atomic-Spaceship/dp/0805059857/ref=sr_1_1?s=books&ie=UTF8&qid=1449250466&sr=1-1&keywords=orion+project
Looks like most websites reference 10% of c as the max speed. Wish I still had the book to look up what the scientists calculations were.
You will have to take my word for it. My library is a mess and I can't find my copy of "Project Orion: The True Story of the Atomic Spaceship"
Freeman Dyson explained how this result was exciting and started the line of research that started the design of this system. He indicated it created a stagnation layer that prevented the plasma from directly touching the metal. The only issue was radiative heat transfer and that was solved by making the plate a large heatsink and lowering the duty cycle of the impinging plasma.
> So, citing someone with a PhD doesn't impress me, I have one so clearly they will give them to anyone.
He wrote the book on it:
https://www.amazon.com/High-Frontier-Human-Colonies-Apogee/dp/189652267X
> Asteroids are actually really far apart (at least in our solar system) and our problems are currently mostly about getting to space not really doing anything once we are there.
That's why we'll be starting with near-earth asteroids.
> Though once you are there I agree it is not necessarily all that costly to get around (just slow), but then you have to either use the metal up there or also suffer the cost of bringing it back down to the surface without killing anyone.
Most of the asteroid material will likely remain up there, yes. Far more valuable in space than on land. But for the extremely rare metals that won't be as true. We will not be manufacturing with rare earth metals in space any time soon.
> This would work much better if more of humanity were in space already and so there was an industrial presence outside earths gravity well, but between now and then it will be slow going.
It would take some time, but it's already completely doable. What's missing is the and the vision. Musk has gone a long way there, his vision to drive towards Mars will do a lot for this.
I forgot to mention, but I live in Belgium. Even used, the cheapest I can find is over $100 :(

Plastic Part Design for Injection Molding 2E: An Introduction https://www.amazon.com/dp/1569904367/ref=cm_sw_r_cp_apa_AjduzbRTN0ZFN
This is a really good one:
Plastic Part Design for Injection Molding 2E: An Introduction https://www.amazon.com/dp/1569904367/ref=cm_sw_r_awd_YhdSub1FSJ2NJ
Plastic Part Design for Injection Molding is probably one of the best books out there on the design of plastic parts. Might also be worth looking into a course or book for injection mold tool design since understanding, draft, parting lines, shutoff, ejection, lifters, gates & runners and all other stuff that contribute to the limitations of plastic part design.
As someone in a similar situation, I'd recommend these two books. They're what were were taught with when I was in college for my Plastics Engineering degree (Bachelors at Umass Lowell). I've had both of the authors as professors.
I'd also recommend this book by Professor Kazmer: Injection Mold Design Engineering if you want to design the mold of a injection molded part. DON"T OVERLOOK THIS. A lot of times our professors were explaining how they'd have to help companies who designed a good part that couldn't physically be molded.
The previous book mentioned by Professor Malloy: Plastic Part Design for Injection Molding 2E: An Introduction is for actually designing the part.
Also, make sure that you get a book on polymer material science. Learn about the different types of plastics, how they handle, ect.
Start with reading some simpler PDFs from resin suppliers like this one.

Practical Electronics for Inventors is an excellent reference for the price.
The Synopsys book club has a list of EE/CS books that are either the clear standouts in their topic area or at the very least a good presentation of the material.
Two less theoretical books you might also be interested in, depending on what you are looking for:
The Circuit Designer's Companion by Tim Williams is a good overview of the practical aspects of turning a schematic into a working circuit. Grounding, how to choose the right type of cap/resistor/inductor, EMC, etc.
Practical Electronics for Inventors by Paul Scherz is similar to the Art of Electronics but is written at a more introductory level. It includes a lot of the important small details that either aren't covered in EE coursework or tend to get muddled in the slog through theory and are therefore easy to forget.
Best way to get back into EE stuff is to build some projects! Hackaday and EEVBlog are your friends, as are Sparkfun, Futurlec, and Digikey.
all I want to say is whatever you do, DO NOT buy This Book I did and I literally have 50 printed pages of errors and corrections. It makes it really hard to work through when you have to not only worry about doing it right but if the book is even right and reference the corrections.
This one http://www.reddit.com/r/arduino/comments/2oenl0/beginner_here_need_advice_on_a_spider_robot_thing/
I posted a list there.
A motor will need more current then an Arduino pin can handle. If you connect one of the 2wd chassis motors under load it can fry your Arduino.
A transistor will conduct electricity when a small current is applied. So with your Arduino pins you can drive larger currents. Kind of like an switch... But Transistors will do more then that. You should grab a copy of "Getting started in electronics" (fun to read, not only for children, easy and still gives you a impression of the "inner workings" of electronics). Or practical electronics for inventors. Written well, not too complicated, but also includes a lot of important math and formulas.
Transistors, FET, diodes and such are basic components you will need all the time and it helps to understand what is going on if something is not working right. With a multimeter, the cheap arduino kit plus a bunch of transistors/led/capacitors and one of the books you are all set.
A H-Bridge module consists out of four transistors and can drive two motors forward and backward instead of just powering it on. These modules start at $1.30 but you can build them as well.
If you need a quick, dirty, and practical explanation of EE concepts, I find that the Practical Electronics For Inventors is a good book. Otherwise the other books mentioned in this thread are quite good too.
On the pure electronics side, I have gone through a lot of allaboutcircuits.com, but not all of it. I bought a "wee blinky" a while back as a simple soldering exercise before I was comfortable enough with soldering to trust myself on more expensive components, and when I realized that I had no idea how it worked I did some research. I quickly found this link http://www.falstad.com/circuit/e-multivib-a.html and the site has some fantastic applets of other circuits that I found very useful in quickly understanding how they work. It is much more useful to me than a simple circuit diagram at this point. I also picked up a used copy of this book http://www.amazon.com/gp/product/0071452818/ref=oh_o03_s02_i00_details on the cheap, which is generally reviewed well other than it containing a lot of mathematical errors. I am comfortable enough with the math to work through it myself if I need to be sure of something, so that was not a concern for me. At some point I might pick up the "The art of electronics", but costs more than I want to spend right now.
On the projects side I have the Arduino Cookbook, which has been handy for helping me pick out projects to bite off from the comfort of my couch. It also has given me a good sense for what can be done in general and how much effort is involved. Obviously I keep an eye to the discussions here, and I also have spent time looking over the Arduino pages. "Interfacing With Hardware" (http://arduino.cc/playground/Main/InterfacingWithHardware) has some really good stuff linked from it. I look at the stuff John Boxall is doing at tronixstuff. I keep an eye on the make blog, and stuff on ladyada.net. I also look at any interesting Instructables I come across. I suppose I regularly scan most of the popular online channels for this stuff.
Other than that, I have just been biting off projects with no particular end goal in mind. I pick a component I want to get some experience with, get one, and do something with it. Then I pick something else and repeat. I have an assortment of parts on order from taydaelectronics that should arrive mid to late this month. When they get here I will experiment with them for a few weeks, and then order some more different things. Right now I am very much in exploration mode.
Edited for typos, and completeness.
Several people recommended more entry-level books in the thread, these may be a good pick if you want results fast. They probably won't give you a full picture, but at least you will be able to put some basic circuits together to see if it's something you want to explore further.
My coworker speaks fondly of Practical Electronics for Inventors, but that's all I have.

At the most fundamental level you're talking about fatigue, fracture mechanics, and the ole S-N curves. A certain aluminum will have a given Fty but over repeated cycles, even if you never near Fty, the metal will yield/crack.
Any geometric change (cutout, fastener hole, etc) causes a stress riser. An empty hole has a stress riser of 3. All of a sudden you dump 2000lbs of load into a fastener in that hole and you're compounding the stress. So it's better to gradually load up the material.
A quick and dirty calculation for this is the "fastener spring method" or "fastener spring stiffness model". Something like that. This is the basis for a lot of FEA models.
A lot of this is from trial and error. Like the cutouts for windows used to be square (with sharp corners) until half the fuselage got ripped off during a flight. Then they started making the inner corners of cutouts rounded.
I think if you google "aircraft durability and damage tolerance" you'll find some semi-detailed info. Although a lot of this will be about crack inspection, etc. some of it will be about repair guidelines/analysis.
These days a lot of fatigue analysis is done by Finite Element Analysis.
Roarks-Formulas for Stess and Strain
That book has endless examples of different geometry and load cases.
If you look at some existing examples, like here you'll see that they are basically a cone with a dome on the top and bottom.
Shells of Revolutions, Pressure Vessels, pipes are Chapter 13 in the Eighth Edition.
I studied it in college. My school had a whole Geography Department.
I didn't go to school for it originally, I found my way there via agriculture and forestry (both use a lot of geographic information systems (GIS)), but since then have done a lot with it.
If you want to learn the basics of geography, I can recommend this book, I view it as the authority on cartography.
Cartography is a science all its own, it's the marriage of design and geography. The mission is to convey information to the reader. It really is a mix of art and science. If you are interested in cartography, you GOTTA read this book.
Any real cartography nerd is also a design nerd, and if they're anything like me, could teach a college course on, say, how typefaces affect a reader's mood. Most great cartographers are also students of graphic design, because, that's a big part of the job. Designers want things to either A) accomplish something specific or B) just plain look beautiful. These are the same charges of the cartographer. I'd love to go on and on about good carto vs. bad; but it would take a decade.
If you want to get into GIS, the software most people use to make maps, and the software I use now as a goespatial analytics pro to do a whole lot more than making maps, I'd recommend using this amazing free online textbook and starting out with a program called Quantum GIS, commonly referred to as QGIS. QGIS runs on PC, Mac, and Linux, it's open source and free, plus that course / textbook is customized for it, and it's highly extensible and flexible.
The industry standard is a program called ArcGIS, which can be had for as little as $100 / year for home use.
If you have any follow up questions, I'm super glad to hear them and answer. Geography is a passion of mine.
One bit of advice: I recommend learning the fundamentals of geography with a beginner's mind - don't approach it like you already learned all you need to know about it in kindergarten. It's a science just like anything else, with a lot of the iceberg below the surface of the water. It also coincidentally shares a name with what most people call memorizing state capitals. Approach it like it's called neural hyperbiomechanics or something; meaning, something you don't think you learned when you were 6.
The Millenial Project: Colonizing the Galaxy in Eight Easy Steps proposed that inverted buildings were the way to go so that we wouldn't be taking away from our parks and making our view claustrophobic.
The twist is that it proposed building the cities on the ocean, so the inverted buildings would be underwater where you could see something. The cities would be power generating plants, shipping power back to the mainland in the form of hydrogen. The cities would also be training grounds for future spacefarers.

2100-2150: Earth gets its first Skycycle...
(also known as 'Rotating skyhooks')
Hey, falingodingo, here is a book that might interest you, Colonizing the galaxy in eight easy steps. While it is outlandish in the extreme, it also has this impossible grandiose vision of easy space exploration. I do think that, if we humans wanted to go to space we would achieve it through fast innovations and cheap designs.
Even if it is not volunteer anything, even it is for profit, we could go spending these 150billion or 1 trillion or whatever. But since there is no need to go, no need to explore (sadly) there is no incentive.
Well, we can always go in the Chinese or Indian ships, many years from now.
That's not a "hyperloop." It's called a Mass Driver, and it is a trope of sci-fi for decades and also is extensively discussed in the Millennial Project by Marshall Savage.
If you think you are depressed by the Trump administration now, read this book and leave yourself feeling like you want to eat a shotgun blast over the things we should be doing and aren't.
The Millennial Project: Colonizing the Galaxy in Eight Easy Steps
IMHO nobody should call themselves a futurist until they have read this book.
After looking through the Q&A on this thread, I noticed a trend in the type of questions asked. If the weird and often unspoken trivia of space travel interests you, I highly recommend reading Mary Roach's "Packing For Mars".
It is very nicely researched and you will probably find answers to many of the unanswered questions here. It is a New York Times best seller, and it is am amazing and amusing book.
If this it the type of question you have, then I highly recommend Packing For Mars which answers a lot of the simple human question of going to space.
Space Chronicles: Facing the Ultimate Frontier
@HardHarry
How much do you think the US government spends on NASA per year?
Go read Neil De Grasse Tyson's latest book
http://www.amazon.com/Space-Chronicles-Facing-Ultimate-Frontier/dp/0393082105/ref=sr_1_1?ie=UTF8&qid=1332717037&sr=8-1
@yogthos
Tyson also mentions that those social programs have largely been addressed -- with typical government efficiency -- already. Alternate energy research is also in progress.
Other forms of science.... well, in these anti-science times that we live in, if it isn't bogus global warming science, it doesn't matter.
For other perspectives, try reading some different blogs:

Dr. Tyson - Are you doing a book tour to promote Space Chronicles: Facing the Ultimate Frontier?
If so, will the schedule be posted on the Hayden website?
If not, and at the risk of bombarding the Hayden Planetarium with mail, is there a proper channel in order to get your autograph on said book?
Like most Redditors, I'd love to get it in person, but NYC is a bit far from San Antonio.
My copy is being shipped to me as we speak and I hope to start reading it as soon as tomorrow!
I really liked The Grand Design by Stephen Hawking. It gives you a perspective of string theory, multiverse, tons of stuff about the universe, origins of the universe, and the philosophy of science that is ment for more entertainment and informing than dense physics literature.
If your looking more for space stuff there is Space Chronicles by Neal deGrasse Tyson
I suggest reading this for some answers. http://www.amazon.com/gp/aw/d/0393082105
Materials science and engineering student here. If it's an intro to materials science type course, mwalsh2010 has covered most of it. Additionally, expect to index planes and directions in crystal structures, solid solubility, mechanical properties testing methods, phase percentage and lever rule calculations (under phase diagrams), phase transformation reactions (eutectic, eutectoid, paratectic, etc.), and various processing methods. You'll probably mainly study metals and ceramics since they're generally not as complex as polymeric and electronic materials.
This was the text book used in an intro course I took. I'm sure there's a torrent of it out there and should serve as a pretty solid resource.
Basic mechanical properties of materials.
If you would like more resources, feel free to PM me.
I agree about Felder and Rousseau for Mass and material balances. It is probably the only textbook that I actually reference (mostly for the charts in the back and the unit conversions on the front cover).
I also like Callister for general materials science information.
Perry's is a wonderful reference.
If you can, pick up a copy/PDF of Introduction to Materials http://www.amazon.com/gp/aw/d/0470419970/ref=mp_s_a_1_6?qid=1404346873&sr=1-6&pi=AC_SX110_SY165_QL70 Extremely useful book for all things material science.

I think it's that E&M is just a more difficult/less interesting subject. If you plan on going to grad school for physics you will almost certainly use this. You'll love Griffiths after dealing with Jackson, as Griffiths acts as a sort of Rosetta stone between English and bizarre Greens Function hieroglyphs.
A class using Jackson E&M for classical electrodynamics is a standard first year grad course. Quantum electrodynamics is part of field theory, and that's usually the next level up. Most people who aren't either particle physicists or theorists don't take it though (which is a shame).
Serious question: what makes you say these are the "standard route"?

this is my very favorite text book from school. It'll get you started, although I don't remember if it specifically had a section on dryers or spray dryers, it has all the physical property tables you'll need, I think chapter 8 was relevant to your question.
this I do not own, but I've heard good things about, will probably have higher level stuff and be more specific to your application.
I like Partial Differential Equations for Scientists and Engineers.
My professor wrote this this book. It is excellent if you already have a memory of PDE's. It is also inexpensive.
That book is quite dry and abstract.
If you want more "why" and applications, try a book aimed at physicists or engineers.
Maybe this one for example
https://www.amazon.co.uk/Partial-Differential-Equations-Scientists-Engineers/dp/048667620X
I don't have any PDFs, but here is a good one you can get for pretty cheap. I used it as an undergrad and still refer back to it.
You might also try this Dover book.
Hope that helps.
I've used this one by Farlow in the past. It's got solutions to most of the common PDE's you'll find in other books, but it's a lot cheaper. It's also less formal than a lot of other books, which may be good or bad depending on your taste.
If you're looking for something that covers a bit more than just PDE's, O'Niel's book isn't too bad.
Graduate or undergraduate level?
If graduate, this is THE book to get.
This is much more applied.

They learn at least the rudiments, if Riley, Hobson, & Bence is anything to go by.
It's great that you want to study particle physics and String Theory! It's a really interesting subject. Getting a degree in physics can often make you a useful person so long as you make sure you get some transferable skills (like programming and whatnot). I'll reiterate the standard advice for going further in physics, and in particular in theoretical physics, in the hope that you will take it to heart. Only go into theoretical physics if you really enjoy it. Do it for no other reason. If you want to become a professor, there are other areas of physics which are far easier to accomplish that in. If you want to be famous, become an actor or a writer or go into science communication and become the new Bill Nye. I'm not saying the only reason to do it is if you're obsessed with it, but you've got to really enjoy it and find it fulfilling for it's own sake as the likelihood of becoming a professor in it is so slim. Then, if your academic dreams don't work out, you won't regret the time you spent, and you'll always have the drive to keep learning and doing more, whatever happens to you academically.
With that out of the way, the biggest chunk of learning you'll do as a theorist is math. A decent book (which I used in my undergraduate degree) which covers the majority of the math you need to understand basic physics, e.g. Classical Mechanics, Quantum Mechanics, Special Relativity, Thermodynamics, Statistical Mechanics and Electromagnetism. Is this guy: Maths It's not a textbook you can read cover to cover, but it's a really good reference, and undoubtably, should you go and do a physics degree, you'll end up owning something like it. If you like maths now and want to learn more of it, then it's a good book to do it with.
The rest of the books I'll recommend to you have a minimal number of equations, but explain a lot of concepts and other interesting goodies. To really understand the subjects you need textbooks, but you need the math to understand them first and it's unlikely you're there yet. If you want textbook suggestions let me know, but if you haven't read the books below they're good anyway.
First, particle physics. This book Deep Down Things is a really great book about the history and ideas behind modern particles physics and the standard model. I can't recommend it enough.
Next, General Relativity. If you're interested in String Theory you're going to need to become an expert in General Relativity. This book: General Relativity from A to B explains the ideas behind GR without a lot of math, but it does so in a precise way. It's a really good book.
Next, Quantum Mechanics. This book: In Search of Schrodinger's Cat is a great introduction to the people and ideas of Quantum Mechanics. I like it a lot.
For general physics knowledge. Lots of people really like the
Feynman Lectures They cover everything and so have quite a bit of math in them. As a taster you can get a couple of books: Six Easy Pieces and Six Not So Easy Pieces, though the not so easy pieces are a bit more mathematically minded.
Now I'll take the opportunity to recommend my own pet favourite book. The Road to Reality. Roger Penrose wrote this to prove that anyone could understand all of theoretical physics, as such it's one of the hardest books you can read, but it is fascinating and tells you about concepts all the way up to String Theory. If you've got time to think and work on the exercises I found it well worth the time. All the math that's needed is explained in the book, which is good, but it's certainly not easy!
Lastly, for understanding more of the ideas which underlie theoretical physics, this is a good book: Philsophy of Physics: Space and Time It's not the best, but the ideas behind theoretical physics thought are important and this is an interesting and subtle book. I'd put it last on the reading list though.
Anyway, I hope that helps, keep learning about physics and asking questions! If there's anything else you want to know, feel free to ask.
I think it depends what kind of PDEs you're going to be doing really. If you're just looking at physicsy things like Laplaces equation, the heat equation and the wave equation then a methods book might be good. My personal choice would be this one but there is a lot of choice out there.
If it's a slightly higher level PDEs course (doing stuff like method of characteristics and conservation laws) then either this dover book or this book were the two recommended texts for my upper undergrad course on PDEs. The second is also recommended on a grad course I'm doing come september, and has loads of material in the book.
If you could give some more details of the course I could probably help you pick one of these easier. :)
Second year UK undergrad here.
In my first year our maths course covered:
These mainly prepare you for thermodynamics and quantum mechanics. Out of all of it I would say the calculus is by far the most important.
If you can get your hands on it, I found this book greatly useful (you only need bits of it): https://www.amazon.co.uk/Mathematical-Methods-Physics-Engineering-Comprehensive/dp/0521679710
Feel free to reply if you have any questions.
A book am using is Thomas Cala and it looks like a good book on it https://www.amazon.com/s?k=thomas%27+calculus+12th+edition&i=stripbooks&crid=348T2AR8JCUJA&sprefix=Thomas%27+Calculus+12%2Cstripbooks%2C187&ref=nb_sb_ss_i_1_19 .

Certainly this book:
https://www.amazon.com/Mathematical-Methods-Physics-Engineering-Comprehensive/dp/0521679710
I have received recommendations for this book from several physics majors and alumni from several different universities. It is a rather thick textbook, but I think most of the chapters can be addressed independently at your current level, especially after this first year of yours. Write it down somewhere in a Google Doc, including the authors and that it's the third edition.
This seems like an unauthorized pirate distribution of https://amzn.com/0521679710 ?
This kind of thing is not the purpose of this forum (for one thing, I assume anyone who really wants to get pirate textbooks can figure out how). Please don’t spam here.
> Meanwhile, we could be researching a technology right in front of us quickly that can benefit us now, help us better exploit resources we do have, help us get to that distant technology faster, and utilize that distant technology once it's time.
Arghh, this is indicitive of such a broken ideology. We can do both. America, alone, could do ALL OF IT if we cut the DoD budget by as little as 20%. And I'm not even suggesting that America does this alone.
I want those other things too, I want research on solutions to global warming and cancer and AIDS and dead puppies, but there's no reason we can't also colonize space.
Please, I'm begging you in solidarity as a fellow human being, do some reading.
Start here but keep following the references and allusions to other sources and, if you've got the fortitude for it, to hard research studies. I can point you in other directions if you like, but that's my personal favorite starting point when suggesting education.
And if you're too lazy to do that, at least look at the goddamn numbers.
I recommend you read this:
A case for mars
Basically, it will become feasible once the classic excuses are out of the way or overcome (money, risk/protection from radiation exposure, bone/muscle deterioration during the trip). Zubrin (the author) is THE dude.
I loved his book: The Case for Mars
http://www.amazon.com/Case-Mars-Plan-Settle-Planet/dp/0684835509
A little old, but this might be what you are looking for: The Case for Mars: The Plan to Settle the Red Planet and Why We Must
hijacking top comment to put in a shameless plug for Robert Zubrin's The Case for Mars, an awesome discussion of why we need to go to Mars.
as /u/deanoyj says, it has all the things we need for an industrial civilisation, and also, due to a quirk of interplanetary mechanics, it doesn't cost much more fuel to go to Mars compared to going to the moon, just more time.
Mars has everything we need, is (relatively) easy to get to, and can act as a halfway station to the asteroid belt, a vast untapped wealth of raw metals and resources. Bonus: colonising mars will force the settlers to recycle everything, which will give them a strong incentive to invent things that would be very useful down here on earth.
Seriously, go buy the book, Zubrin explains all the issues in detail and so much better than I ever could. I went in thinking we should go to the moon, and came out convinced we need to go to Mars, and we can do it fairly cheaply, if we accept some modest risks.
'Distances' in space are odd, even though the distance between two points may be further than another trip, it may not take that much more effort to get there. The Moon is far closer than Mars, and takes a few days rather than a few months to arrive, but I hear you need about the same size of rocket. Distances can be measured in required Delta-V, or change in velocity. Heinlein, a mid 20th century science fiction author (Starship Troopers, Stranger in a Strange Land) said, “Reach low orbit and you’re halfway to anywhere in the Solar System.”
'The point of Heinlein’s maxim is that the same amount of energy it takes to go from Earth’s surface to Earth orbit is roughly equivalent to the energy required to travel from Earth orbit to the planets. The point is that if you can get to orbit, you have the capacity to also reach most of the solar system.' Source
So, the Moon isn't necessary any easier to get to than Mars is, barring problems with months of radiation exposure, low gravity exposure, and additional effort required to launch from a planet with a larger gravity well and atmosphere.
In The Case for Mars the author explains a few resources that Mars has which allow synthesis of fuel for both rockets and internal combustion engines, growth of food, and with a not-insignificant amount of planning/science/care, become self sustaining far easier than a moon colony could.
Also on the technical side, if you want some of the inspiration for the mission architecture, try The Case For Mars by Robert Zubrin. For an insightful critique of TCFM from 18 years later, try The International Mars Research Station by Shaun Moss.
Read "The Case For Mars." We totally have the tech, just politically can't get the budget. And the most expensive part of the budget is bringing someone back, nearly as healthy as they left. If you don't need to bring someone back, or even live very long once they're there, it's a lot cheaper.
Mars One is a company that is dedicated to doing just that. Also be sure to check out The Case For Mars.

To become a beekeeper just buy the hives and bees (all that other stuff is really optional). Most states require you to register them.
To become a good beekeeper you should look for your local Beekeeping Assoc or Agricultural extension office and see what classes they offer and start taking them before buying anything. They will help you determine what you need, what works for your area and how to do things in a manner that you hopefully don't lose the bees.
There are no certifications required but there are some out there. The University of Florida has a 5 years Master Beekeeper Program is one. UF also offers 3 different Bee Colleges during the year in two places in the state, and the Caribbean. Local associations hold day courses and Ag offices have done longer multiple session training courses at least in Florida. Look in your area.
You can also start learning on your own. Start with something like The Beekeepers Handbook.
The best advice I can give you is find that local association and start there. They will have experienced beekeepers and be able to point you at local resources.
I haven't priced stuff in a long time, but it's not too bad to get one hive up and running. Extracting and bottling the honey is another expense unless you find someone with the equipment. I got my hives and bees from these folks- https://gabees.com/ and most of my other equipment from Mann Lake or Dadant.
For anyone looking to start, this book is a great first purchase-

You might be interested in Project Orion and this book about it.
Some of the scientists who invented the atomic bomb, after that was done, worked on some wild ideas at General Atomics in San Diego. One of those ideas was for a spacecraft propelled by a series of small nuclear explosions. Seriously. A bunch of little atomic bombs going off in sequence in the back of the craft. They had the shielding all worked out, the required thrust, etc, in some detail. Could actually work for spacecraft leaving from earth orbit and provide a way to get to, say, Mars, and back in a relatively short time. George Dyson, the son of one of the scientists, wrote an interesting book (still available) about the project if you want to follow up on the details.

To add, to this, one of the ways for humanity to harness Sun's energy is a Dyson sphere. However, there are A LOT of technical challenges to overcome. A good book I read about some of the challenges and possible solutions to harvesting energy from the Sun is The Millenial Project.

Read Packing For Mars
I ordered the third edition last month, at the time I read that the companion for that version was not yet released. Is that the new companion?
I found this on amazon, it has a recent publishing date, but I don't see what version it is.
https://www.amazon.ca/Learning-Art-Electronics-Hands--Course/dp/0521177235/ref=sr_1_2?ie=UTF8&qid=1458182205&sr=8-2&keywords=learning+the+art+of
Let's do a bit of numbers.
Let's for the moment assume you smashed several comets of water into the planet to build your atmosphere. You only have 40% gravity so you're only going to get 40% atmospheric pressure. To get pressure that low on Earth you have to go to 22,000 feet or 7,000 Meters. In case you don't know, there aren't any cities at that elevation as almost all people prefer to be able to breathe. The highest cities on Earth hover around 5,000 meters, 2,000 meters below your baseline number.
How long the atmosphere lasts is currently unknown despite your assertion:
>Incorrect: The atmosphere strips away over millions of years, more then slow enough for an atmosphere to form.
You didn't cite your source for that assertion. What we can state confidence is the current loss rate is being measured at the end of a very long loss process. If you look at vacuum pressure curves you'll see that most of a gas is evacuated early on - getting a really hard vacuum at the end takes a lot of time which is when the Mars MAVEN project measured.
Did I forget to mention that Mars doesn't have a magnetic field? The magnetic field steers the solar wind away from Earth so that when the sun hurls a bolus of hydrogen at us every so often, it doesn't strip away our atmosphere. Your 40% gravity is going to need that magnetic field help and it doesn't have it. Yes, there are ideas floating around on how to counter that issue but right now they're best labeled ideas, not fact.
You write:
>Incorrect: the moon has very little in the way of useful materials, which is why people are interested in Mars in the first place.
Absolutely no idea where that comes from. Hell, the Lunar astronauts brought back a large chunk of Anorthosite they found just lying on the surface. We've known for quite some time that there are plenty of minerals on the Moon. The astronauts weren't lucky, there's stuff all over the place. It's just damn expensive to get to so it stays put for now. It shouldn't be a surprise - the moon formed from the earth after all.
>Just silly: Do you have any idea how much energy it would take to move orbiting cities?
Yes, it would take huge amounts of energy. Fortunately, we have lots. You can go nuclear or solar - your choice.
Until it was killed by the 1963 atmosphere nuclear test ban, the United States had been working on Orion. Orion would have launched a skyscraper into orbit. When they were designing Orion, they built this building to keep the designers' sense of scale as to what nuclear power made possible. The building was scaled to be a cross section of the rocket. To reinforce the point, they were going to fly a barbershop with old fashioned barber chairs because mass wasn't a launch constraint as it is today. Cities are made up of skyscrapers and since we're mining the moon, you can have as many as you want. And you don't have to lift them off Earth like Orion was going to.
Don't like nukes? You can use solar power to sail around the inner solar system. Extra-terrestial solar won't generate power like nukes will but it will provide the energy necessary if you're not in a hurry.
I refer you to High Frontier: Human Colonies in Space for lots of details.
My last point.
Your call to remove my post is censorship to enforce a point of view. I may be wrong or you may be wrong or we may both be wrong but censoring each other isn't the path to truth.
If you don't agrees with a point a view, refute it. The truth emerges from that process. Calling for censorship to preserve a point of view you're SURE is right is what the Catholic Church and the Soviet Union had in common. We're seeing a resurgence in the call for censoring speech from people who really don't know or forget their history.
