It can be daunting to move from the abstract idea stage to the realm of bank accounts, taxes, and liability. Sometimes, it can feel like you’re making arbitrary decisions, but we’re going to wade through the legalese together. Things are about to get legit.

In which John Green, Hank Green, and Emily Graslie teach you about the Anthropocene, an unofficial geological era that covers the last century or so, in which humanity has made massive progress. We've discovered the Higgs-Boson particle, and awesome electric cars, and amazing smartphones. So all this collective learning and progress has been good for everyone, right? Maybe not. We'll look at some of the pros and cons of all this "progress," including environmental impact, changes in the way people live and work, and political changes and wars that come along with the modern world. We've come a long way, but there's a long way to go. Crash Course will also take a look at what's going to happen in the near future. If we manage to make our way through the coming bottlenecks, we could be OK in coming centuries. Don't get too hopeful, though. The Sun will eventually die, and the Earth will be destroyed, and later the universe will eventually experience heat death. But we won't talk about those downers until next week.

In which John Green teaches you how Russia evolved from a loose amalgamation of medieval principalities known as the Kievan Rus into the thriving democracy we know today. As you can imagine, there were a few bumps along the road. It turns out that our old friends the Mongols had quite a lot to do with unifying Russia. In yet another example of how surprisingly organized nomadic raiders can be, the Mongols brought the Kievan Rus together under a single leadership and concentrated power in Moscow. This set the stage for the various Ivans (the Great and the Terrible) to throw off the yoke and form a pan-Russian nation ruled by an autocratic leader. More than 500 years later, we still have autocratic leadership in Russia. All this, plus a rundown of some of our favorite atrocities of Ivan the Terrible, and a visit from Putin!
