When I took my electronics class I completely hated Sedra and Smith during the first half of the semester. As things began to make sense and my time playing at the lab increased I finally understood how awesome the book is.
There's the Brian Wampler book that people always talk about in this sub, I don't know if it's exactly what you're looking for, but you should check it out anyway, it's a great source.
I was thinking about using Designing Analog Chips by Hans Camenzind along with The Art of Electronics by Paul Horowitz as a guide for projects to do. I also recognize its important to know to design digital electronics (even though it may not necessarily be my strength) and know how to do research if I do end up doing the PhD so I was also looking into these books: link 1, link 2, and link 3. Are there any other books I should look into?

Hmmm.....
>why would anyone use mirrors when the cost of a roll of quality foil is only a few bucks and can be cut to size?
A mirror was likely not used, Mylar was. You can see in certain areas where the Mylar was not flat causing distortions. Either that or a first surface mirror like material that behaves like Mylar. Optically they would behave the same. The OP never actually stated what the material was.
>Depending on the intensity of the light, using shitty mirrors has a high chance to cause light issues.
Prove it- the burden of proof is on you as the person making the claim. I've done a lot of testing and have never seen light burn from any mirror or mirror like material with indoor grow lighting levels.
>The issues that foil could cause all stem from shitty application and carelessness of installation. If you keep your foil smooth and unwrinkled, you'll have zero chance of light issues.
I used wrinkled and non-smooth foil in my lighting guide to demonstrate that at half full sunlight intensities plants were not burning. Due to non-photochemical quenching alone one should not go past these lighting levels which is about 1000uMol/m2/sec. I even formed concave structures to try to burn plants. It never happened. In this case a quantum light meter was used instead of a more accurate NIST tracable spectrometer.

>Glass absorbs light? Interesting theory or use of the word "absorb"
Ok......
Of course glass absorbs some light. For example, one can easily construct an "infinity mirror" and easily visualize the absorption of glass.
This is optics 101 here and why camera lenses will have optical coatings to help with the internal reflections of light that causes greater absorption. For example, a camera zoom lens with 20 optical glass elements (up to three glass elements may be used to create a single lens to ensure that the light is all focused to the same point) without coatings and much of this light would be lost due to internal reflections. The glass elements will have slightly different refractive indexes to accomplish this focusing of different wavelengths of light and help eliminate chromatic aberrations.
These internal reflections are absorbed by the glass.
Prime lenses don't have this problem as much but will still have optical coatings so that not as much light is absorbed by the glass.
In typical imaging systems, this improves the efficiency since less light is lost (wiki quote). They are referring to the absorption of light with glass. The transmittance of a single element (two surfaces) may be as low as 90% depending on the type of glass with no optical coatings. (edit - here's a sample transmittance chart).
Due to being reflected by a back coating the light of a "normal" mirror has to go through four uncoated surfaces which is why second surface mirrors should not be used as previously mentioned.
There will also be some scattering inside glass that also gets absorbed since glass is a non-crystaling material which is more prone to irregularities called grain bounderies.
An good example of glass absorbing a lot of light is the presidential limo with four inch thick glass (and polycarbonates). This is really more due to the Beer-Lambert Law because of the thickness of the material:

You wanted interesting theory on glass absorption and I just kindly gave it to you. Lighting and lighting theory are my specialties and honestly you are going to get way above your head here if you do not even understand the basics of how glass behaves.
edit- if you want to learn more buy this book (I have the 1st edition):

I was always able to remember that last name because of his book. I wish I had met him when he was still around.
Look no further.
This is, in my opinion, the best resource for semiconductor physics.
I reached out to a friend (who has the Amateur Extra license) for guidance and he recommended the canonical ARRL book (link). I've been reading that and it's been VERY helpful. It organizes all the questions by subject matter and teaches more holistically, while still letting you see the exact content in the exam.
Here is a link to a pretty thorough course in beginning analog circuits. I don't know how much you would get out of it seeing as you would probably know most of it from being a physicist, but it's there for reference. The next step up would be this book by Sedra and Smith. It will start off with Thevenin and Norton equivalents and work up from there. The book is very large and contains damn near everything you need to know about analog circuits (even has a chapter on semi-conductor physics :)). If you have any interest in digital circuit logic you can go here. Also, I think I see an Arduino in the article picture. There is plenty of documentation on their website. If you want to know more about microprocessors in general, Amazon has a long list of books that could probably suit your needs. Hope that helps! :)
Crystal Fire
If it's the Sedra and Smith book I'm thinking about, probably because it's an integrated circuits book, which would be totally inappropriate for a beginner.
I'd start here!

Honestly you can't go wrong with a for dummies book for easy introductions, "electronics for dummies" would probably be helpful for your situation.

If you put in the time and effort you can pick it up fairly well. If you really want to get into design and modding and stuff I'd say find a few fairly simple circuits and socket a bunch of the components so you can see how changing various parts impacts the sound. This is supposed to be an interesting book from Brian Wampler. Most of the negative reviews basically bash it for basically taking informations and schematics you can find online and putting them into a book, but the analysis and organization helps you work through some of this stuff. This is another good one too from Craig Anderton. The Anderton tube sound fuzz is the basis for one of my got to distortions.
First do the hand calculations for the patch antenna size, they can be found in many textbooks.
Next, simulate the antenna and see how close it matches your hand calculations.
I can recommend:
Microstrip Antenna Design Handbook by Bahl, Bhartia et al.
Good antenna theory textbooks are:
Antenna Theory and Design by Stutzman and Thiele
Antenna Theory: Analysis and Design by Balanis
Older editions can be found on AbeBooks and are just fine.
Antenna-Theory.com is a good online antenna reference.
Try posting in /r/rfelectronics for help later.
And I get what you are saying. Thank you for your comment. I was opposing the usual ads with the "sweeter buds" claims and scepticism is like a Pavlovian reflex ;) I read two Cervante books and even he just scratches the surface on soil biology explains all the basics, reducing it for relevant growing routines. It is a whole class itself. Just like lighting.
Cannabis cultivation is a lifetime learning process and I think besides shading some light onto cliche bro science nonsense it also cleared up some up my half-knowledge. In this case a niche of soil biology, which is deep as an ocean trench. I also enjoyed the discussion between flushing from a strict scientific point of view and the opposite. In the end it is all about learning and always being open to adjust ones "data base". I ordered a "Teaming with Microbes: A Gardener's Guide to the Soil Food Web" so this post was meant to be productive.
I am still reading and trying to understand Ross McCluney's Introduction to Radiometry and Photometry. Dense information, deep into the field, but highly recommended.
Cheers
Here is a good book to get you started.

As you're an engineer, Quantum Mechanics for Scientists and Engineers might be of interest. It's written by a EE professor at Stanford.
A potentially nice optional feature of this is that Stanford offers a free online 9-week course based on this book with the author giving the online class. The latest offering of the course started Oct 4 and goes until Dec 16. If you're interested in that, I don't know if you could take it starting on your own now with access to the videos and course materials, or if you'd have to wait for the next offering. Here is a review by someone who took this course a couple years ago.
Disclaimer: I haven't read that book or taken this online class myself; it's just a potential idea that might be a fit or not
ill give you the second edition of this book for free if you want to pay for shipping. probably 15 bucks for shipping in the US.

You will learn more about electronics than you will ever need to know, in one book :)
https://www.amazon.com/Science-Analog-Circuit-Design-Engineers/dp/0750670622/ref=sr_1_1?ie=UTF8&qid=1506116476&sr=8-1&keywords=art+and+science+of+analog+circuit+design

I used alonso and finn:
http://www.amazon.com/Physics-Marcelo-Alonso/dp/0201565188
It's big, it's fat, but it has a lot. It's not the best book around, but you'll find everything you need from basic mechanics to statistical physics, thermodynamics and basic quantummechanics. It builds up to the equations of Maxwell quite nicely, however in general the structure is quite flawed. I wouldn't recommend it if you like them fancy books with shiney pages and purple boxes with "Interesting note!". It's black and white, bit outdated, very dry, and hard to follow. This book was rarely used in the US, but it was a huge hit in Europe. The first edition was written in the sixties, this is the 1992 (sixth? seventh?) edition.
On a sidenote though, if you DO like fancy pictures and easy math, AND want to learn astronomy, I can recommend the following book:
http://www.amazon.com/Cosmic-Perspective-5th-Jeffrey-Bennett/dp/0321505670/ref=sr_1_1?ie=UTF8&s=books&qid=1239527234&sr=1-1
It is very airy, intended for non-physicist use actually. It's quite embarassing sometimes to read it as a second bachelor in physics, but it is a breeze to read none the less. It goes over everything from basic earth rotation and it's consequences, up to black holes and quasars. It's not very mathmatical, it's just the storytelling behind the theory, with sometimes a bit of math in a small box, which is still sometimes even at highschool level.
If you are looking to become a specialist in quantum mechanics, I used to following book:
http://www.amazon.com/Quantum-Mechanics-2nd-B-H-Bransden/dp/0582356911/ref=sr_1_1?ie=UTF8&s=books&qid=1239527384&sr=1-1
It's quite interesting, and it explains everything. It starts off with black body radiation, then starts with wave mechanics, and then you end up at matrix mechanics. It does require a lot of mathematical insight though, even though some basic principles such as dirac distrubtion, and fourier transformations are explain in the appendix.
If you want a bible to carry around with all the math help you need:
http://www.amazon.com/Mathematical-Methods-Physicists-George-Arfken/dp/0120598760/ref=sr_1_1?ie=UTF8&s=books&qid=1239527524&sr=1-1
This is the book I own. It's a bible, I can guarantee you that. It's not meant to start by page 1 and read it through till the end. It's something you use to regularly look stuff up in. It has everything you need for an undergraduate course in physics. It also requires some first year calculus knowledge though. It starts off by assuming you know everything about integrals and derivatives. I think the rest is explained though. You even get a small introduction to physics-applied group theory. If you ever need a polynome, it has everything from Bessel, to Chebyshev.

I recommend Sparkfun or Mouser for parts. Just be careful that you pick breadboard-able parts (through hole / pcb) and not surface mount (smt).
If you can afford to pick up an Arduino UNO or similar there are a bunch of tutorials online for simple circuits with those and you'll also learn a bit about programming (if you don't know already).
The problem with leaning electric circuits is that it's hard to do much that's exciting until you've learned quite a bit unless you use a microcontroller like an Arduino.
For learning the basics I'm a fan of this book.
Electric Circuits by James W. Nilsson and Susan Riedel
I'm sure you can find this cheaper than on Amazon.
Good luck and don't get discouraged. There are a lot of odd concepts in electronics but you'll get them if you try. (YouTube is your friend.)
Okay, you're definitely at the beginning. I'll clarify a few things and then recommend some resources.
I feel like I've gone off on a few tangents, but just ask for clarification if you want. I'd be happy to point you towards other resources.
Wikipedia has a great intro article on this chip. Youtube also has at least a million great videos showing how to use the 555. This is a chip that as an EE you should absolutely know forwards and backwards. While it's less useful nowadays - thanks to microcontrollers that cost less than a few cents - it's still an amazingly useful chip that can time pretty much anything.
A book to add to your reading list
...which is written by the 555 IC's designer, Hans Camenzind
Looks like he released the 4th ed recently
He also has Modern Antenna Handbook
And several others, thank you for bringing my attention to him!
Selinc.com has a lot of white papers and application guides that can help.
Protective Relaying: Principles And Applications (Power Engineering) https://www.amazon.com/dp/1574447165/ref=cm_sw_r_cp_apa_i_C1poDbEZP4C2F
Is a great book too.
According to Much ADO about almost nothing: Man's encounter with the electron, pages 193,194: (emphasis mine)
>"Bill [William] went to Hollywood high school and then on the the California Institute of Technology, where he studied physics. In 1932, with a B.SC., he went to MIT on a teaching fellowship and emerged four years later with a Ph.D. Then he joined Bell Laboratories..."
This is considered one of the better texts on the subject: Protective Relaying, Principles and Applications
This is the first book I read on the subject! It starts with the water-flow analogy of electricity and identifying components, and goes up through analog and digital circuits with some great projects along the way. I built the analog power supply project inside the housing of an old radio and still use it at home.
Tab Electronics Guide to Understanding Electricity and Electronics
The Physics of Solar Cells
Briefly, increasing area of a device will generally increase the total current since the current density is fixed (in most cases). However, increasing the area can reduce the effect of side surface recombination which should increase the open circuit voltage slightly. But for a given device that's relatively large, increasing the area will increase I_sc linearly (as J_sc stays fixed). V_oc would be mostly unaffected.
If you're looking for a Semiconductor Physics book then Pierret is the standard from what I've seen.
From a circuits and applications side, go read "The Art of Electronics", "Troubleshooting Analog Circuits", and all the app notes from TI, Maxim, National, and Linear.
You should first decide what you want the thing to do.
Read this:
https://www.amazon.com/Electronics-Dummies-Cathleen-Shamieh/dp/0470286970
Or check youtube for intro to electronics/circuits videos, there are tons. You'll need to be able to read an electrical schematic, since you're going to have to create one.
Then get yourself a microcontroller like a Raspberry Pi.
Then watch some coding tutorials.
https://www.youtube.com/watch?v=QrUvhzz5bRs
You'll need a multimeter, a soldering iron, wire strippers, crimping tools, basic hand tools. You should also watch some videos on how to properly fabricate wiring harnesses. You'll need a working knowledge of fasteners and materials.
Don't set out to make a robot your first project. Start small, like getting an LED to spell out "Hello World" in morse code or something. Move up to something with one moving part that does only one thing. Up the complexity of your projects as you go.
When I took that class we used the same book, which I found to be one of the better ones I've used.
A lot of people seem to recommend the Sedra book
http://www.antenna-theory.com/intro/books.php
> A good book on antenna theory would look nice on your bookshelf. And girls really like antenna books. Sometimes you get sick of reading things on the internet, and want a comprehensive antenna book to read. On this page, I'll review some of the popular antenna books available.
Seriously, you could do worse than Antenna Theory by Balanis:
https://www.amazon.com/dp/1118642066
If you have the time to read, I learned a lot from Electronics for Dummies.
Like dtfgator said start looking through the [IEEE PES] (http://www.ieee-pes.org/) stuff. I am currently and undergrad doing some research in this, so I don't have much field experience. My experience so far has just been setting up simulations (some hypothetical and modeled our campus grid) in Power World and ATP. I'm sure there are many other programs that have advantages over these two but it's what I'm familiar with.
Knowledge of how to design and analyze a power system is an obvious necessity. I have not designed anything yet, but have learned fundamentals from this book which also has a lot of examples to use or set up in Power World. There are also a few courses on youtube somewhere.
Double slit experiment for the most basic explanation:
https://www.youtube.com/watch?v=DfPeprQ7oGc
And then, just get this book. Everything that I learned from the internet informally was covered in chapter 1 of this book:
Quantum Mechanics for Scientists and Engineers:
I remember this one being pretty good. Mainly used it in the first couple of intro classes, so if you're doing a lot with transistors it may not be very useful.
http://www.amazon.com/Electric-Circuits-9th-James-Nilsson/dp/0136114997/ref=sr_1_1?s=books&ie=UTF8&qid=1425422648&sr=1-1&keywords=nilsson+riedel+electric+circuits
It's not a reference manual, if that's what you're asking. If it was like mine, it covers all of the basics in analog circuit theory and analysis... how things work, finding values, and probably some design. Far beyond use of CAD tools (although that was probably covered too).
http://www.amazon.com/Electric-Circuits-9th-James-Nilsson/dp/0136114997/
I always think of a bjt as a diode that blocks in both directions unless a voltage (and since it's a diode a little current must move) is applied to the base. Cutoff means no current flows, so you can remove voltage at the base to prevent current flowing from the collector to the emitter. Breakdown is what happens when you put soooo much voltage into something you literally break it. (Eg put too much voltage across a diode and it will leak current even though it should theoretically stop it)
There is a funny area used for amplification that is really complex where I usually just pull the bjt equations from Sedra/smith's http://www.amazon.com/gp/aw/d/0195323033?pc_redir=1395092360&robot_redir=1 and treat it like a math problem
You've got a lot of good advice in this post that pretty much covers what I was gonna say. I can relate to you when you say that you really understand the subject by working through all the details and the math. However, I've found that when it's time to actually put theory to practice, a lot of times you can't do it directly because the problem at hand is way too complex. And like you said, that approach takes a very long time. So, a compromise I've made is that I just start doing the project, and then learn the theory in parallel. That way, you sort of start to get both the intuition and the solid foundations behind what you're trying to work on.
Also, a practical book I'd recommend is Practical Antenna Handbook. I've skimmed through it and it seems like a really good book to get a feeling for working with antennas. It's definitely on my to-read list. If you really want the nitty-gritty of antenna theory, I've heard good things about Balanis and Kraus.
You have to learn the concepts of digital signal processing. There are alot of really good books out there on amazon. You can choose to implement these algorithms in many ways, in C++ using various audio libraries, in CUDA/OCL on a GPU or even in hardware level via Verilog/VHDL on an FPGA.
If you want to deal with raw circuitry, you need to learn analog signal processing, you might have to learn the concept of analog electronics. BJT's/OpAmplifiers/ClassA/AB/D etc. I recommend this book, it is fantastic.
http://www.amazon.com/gp/product/0195323033/
I recommend reading up the concepts of DSP first. Discrete Fourier Transforms, frequency manipulation such as low/high/band pass filtering. All the various concepts basically. This coursera site shows most important concepts.
https://www.coursera.org/course/dsp
Also, unless you are working on an FPGA, there is not much point testing/starting out on an embedded system. Try it out on your PC/Mac first
Well first you’ll probably want to get a license to use it. Assuming you’re in the US, I recommend this book to help you get started. It’s not very difficult to get the entry level license (Technician), but if by “long range” you mean global, you’ll need to upgrade to a license that permits use of those frequencies, which would be the next step up (General).
There’s a lot of possibilities with this question and I think you’ll probably get more help at r/amateurradio as r/radio is more for broadcast radio rather than two way communication.

Thanks for verifying that for me, it's left me a little concerned about my mathematical skills. I can't seem to get it to adjust to the range I desire, it seems to range from 15-20 volts and I can't seem to get it any lower, even after replacing the zener reference with an actual 7805 regulator. I'd like to be able to change the voltage of this with a single pot, but as I said it's not doing the range I desire. Do you have a suggestion for any good schematics for op-amp or transistor based adjustable voltage regulator that you've enjoyed? I have a book which contains several chapters leading up to the construction of a dual adjustable supply, but I can't seem to find much direct information in the book regarding what the expected range would be, so i don't know if I should build it or not yet. I know I could always grab a couple lm317's to build a nice dual adjustable supply, but that really takes the fun and learning out of the whole project for me :P
Thanks!
My school had a course that all EEs took that covered the basics like ideal transformers and induction motors. Then there were power specific courses that got into more detail with phasors, per unit, etc. This was the book a few of the power specific classes at my school used.
Wow, OK. Agree about MS. There was also Crystal Fire about the birth of the transistor which told much the same story (although I can't imagine William Shockley would have been impressed). I'm sure you are right in that AT&T didn't want new things like touch phones, let alone cell phones. But I haven't seen much evidence that basic research is done by industry any more. Also, IBM did the same thing and wasn't broken up by government action but by competition. Also, there are only so many phone lines. Which makes the same argument that net neutrality needs to be a thing.

I am a current EE student right now and saw you ask in another comment about book recommendations so I thought I would throw a few in:
You should probably throw in some electromagnetic and semiconductor physics for good measure as well.
Sedra and Smith is a great textbook if that is not what you are using already.
What part of Electronics I was the most troublesome? Large signal analysis? Small signal analysis?
During my engineering degree I studied semiconductors extensively. The two books I would recommend to you are Pierret for device fundamentals, and I think this is what I used for device fab. Since your lab does optoelectronics, I'll also recommend Kasap. These are all very much engineering oriented, so they are good if you're looking for a functional understanding of how these devices work.
Also, some of the solid state physics (learning about density of states, electronic structure, etc.) is probably better learned from Mermin and Ashcroft.
I have Michael Wilson for EE112. I found the 9th edition of the textbook online but I'm not sure if it's the same one. Here's the cover.
Thanks for the help

I know absolutely nothing about electronics but Amazon reviews are not liking this book at all.
EDIT: Many reviews are tipping to get this one instead :Fundamentals of Electric Circuits
Yeah, the laws explicitly allow transmission outside of your licensed limits for the preservation of life and property. The test is super easy. You should read the book it's based on at least once to get a broad understanding, and then download a free app that gives you all the test questions. Just go through the questions until you've memorized enough to Ace the test.
Testing costs around $15. I'd strongly recommend taking all the tests through amateur extra to get access to all amateur bands. If it takes you an extra couple months to memorize all the questions, that's totally fine (unless you're in a hurry to transmit, then just study more!).
In short, you'll need $20 for a Kindle version of the arrl manual (you can skip it and read free or lower cost manuals if money is super tight, but this is the official guide that you can come back to).
https://www.amazon.com/ARRL-Ham-Radio-License-Manual-ebook/dp/B07DFSW94G
Then you'll study with a free app.
https://play.google.com/store/apps/details?id=com.iversoft.ham.test.prep
You can just Ace the tests from the app by memorizing all the questions, but there's HUGE value to actually understanding the content in the study guide that you won't get from memorizing a couple hundred question answers.
Then, take a test for a variable cost -- mine was $15 (and that covers all three tests if you take them all, it's just a fee to help pay for the site and materials).
Finally, or maybe first, get yourself a cheap ham radio like the baofang UV-5R. It's only about $20, so I'd just get it and start playing with the relatively complicated controls (plenty of guides on the internet) and worry about any upgrades long into the future when you have money and you're sure you're interested.
