This will probably sound lame, but one of the most interesting history books I read was "Russia and the Golden Horde"

It gives a comprehensive breakdown on the impact of mongolian leadership on the development of the early russian state and also serves as a great introduction to the long history of medieval peasant revolts which are a constant in Imperial Russian history.

I had an awesome professor that let me do a custom course on the history of uprisings and revolts in Russia and it was some of the most fascinating things I've ever read, there's so many amazing stories from pugachev up to the bolsheviks. Personal favorite book is about the Anarchist Women that help assassinate Tsar Alexander II 5 Sisters: Women against the Tsar

It's true. Only 60 million make it into the top 1%, with $34,000/year. Half of that 1% (29 million) live in the US. The number comes from Branko Milanovic's work, and his book The Haves and the Have-Nots.

Here are some articles on it from well respected organizations:

However, keep in mind they all cite the same source, which is Milanovic and his book, and were all written at around the same time, so I assume it was Milanovic's publisher paying a PR firm to get these written. But that's pretty much how most media works now days. So if you are still skeptical of the number, I suggest reading the book, or finding some of Milanovic's published papers and reading through the methodology used to come up with his numbers.

Another fantastic book on the subject is Thomas Piketty's Capital in the Twenty-First Century. I highly recommend reading it. Picketty actually expected huge amounts of controversy when he released his book, and was surprised to find out that not many people disagreed with his methodologies and conclusions. Which is pretty scary in itself.

Definitely. For further reading, I recommend Wiesel's Spaceflight Dynamics.

It is much easier for a satellite to maintain its orientation if it is spinning. Otherwise, it starts to drift and point in different directions. Satellites must then be designed to spin on one of the two stable axes, because if it ends up on the intermediate axis it will wobble (and you lose your TV, cell phone connection, etc.).

What this usually means is distributing the mass of the internal components a certain way, or even adding ballast weights to set the moments of inertia as desired.

A pack of playing cards may be a simple rectangular prism, but even a complicated object like a satellite exhibits the same dynamic properties... it's just a lot tougher to figure out what the axes are.

Beyond stabilizing satellites, any maneuvering in space needs to take these concepts into account. A maneuver on the intermediate axis will be unstable. Spacecraft need to either compensate, or perform maneuvers on stable axes as much as possible.

P.S. I think they have to be designed to spin on one axis actually, but I can't remember if it's the minor or major axis. As energy slowly decays, the spin will gradually transition to one of the axes... but college was a long time ago.

Yeah, I was just making a stupid joke.

As for the Islamic view of Genghis Khan, it depends on perspective. Genghis Khan was tolerant of Muslims and even sought after their intellectuals. But he also destroyed their populations. A lot of the estimates of the deaths caused by Genghis Khan's conquest are exaggerated, but that doesn't really affect the perception in much of the Muslim world. There are also a lot of dubious claims as to Genghis Khan's brutality.

It's true, from any perspective, that the Mongol conquest put an end to a long period of Muslim prosperity. Since the days of Mohammed, they had seen very few serious military losses. The common belief among Muslims prior to Genghis Khan was that their prosperity and military success was undeniable proof of the validity of their beliefs. They felt that Allah had blessed them with the ability to win battles and spread their religion. So Genghis Khan turned their world upside down.

All of my understanding of Genghis Khan and Muslim history come from Genghis Khan and the Making of the Modern World and Destiny Disrupted: A History of the World Through Islamic Eyes, both of which I highly recommend.

I've been fascinated by Celtic art since I first saw photos of the Book of Kells, Book of Durrow and the Lindisfarne Gospels many years ago.

I found this book that explains how these complex drawings were made. It's amazing how something so complex can be made with such simple methods.

This is a good book on the subject that I enjoyed.

That's the easiest to digest 12 pages of viewable data I have available from either side of the arguement. I should have linked directly to the paper, not the host. Its literally the first thing that pops up on google when you type, "environmental effects of increased atmospheric carbon dioxide."

If you are having some trouble with insomnia, I encourage you to read "Unstoppable Global Warming" by Singer and Avery. I subsist on a diet of data and beer and I couldn't get more than 70% of the way through.

If you like this, you may enjoy this book that explains how to do these and several other constructions.

> There is a debate among scientists as to is viruses are actually alive

An interesting book that spends quite a few pages discussing this is Life as We Do Not Know it: The NASA Search for (and Synthesis of) Alien Life by Peter Ward.

Wait till you see this

Basically the Old Masters had a bunch of aids like this that helped them create sublime, photorealistic renderings in oil.

A demographic shift taking place nationwide. This book puts it in a good context.

The Beekeeper's Lament is a book following a single beekeeper. Interesting and informative.

This is all I could find on Amazon. Do you think it will react similarly?

If you find this gif interesting for the battle it shows, I can't recommend reading Gotham enough. Fascinating read on the early history of NYC. It is a tomb though, so be prepared for only reading one book for the next six months.

Yup, Ferdinand de Lesseps was the one who was given much of the credit for the construction of the Suez Canal. He tried to do the same in Panama and make the whole canal at sea level but failed miserably and almost bankrupted France.

The book by David McCullough on the Panama Canal is an amazing read https://www.amazon.com/Path-Between-Seas-Creation-1870-1914/dp/0671244094

Here is a whole book on the circulatory system for you.

It explicitly mentions “Vascularity is enhanced by extremely low body fat (usually below 10%) and low retained water, as well as the muscle engorgement ("pump") and venous distension accentuated by the vigorous flexing and potentially hazardous Valsalva effect which characterize competitive posing. Genetics and androgenic hormones will affect vascularity, as will ambient temperature”

Vascularity is a real thing and it is most effected by lower body fat.
