The Harlem Renaissance produced many remarkable artists, writers, and thinkers. Today we'll talk about one of the most interesting minds of the time, Zora Neale Hurston. Hurston was an anthropologist by training and spent much of her career studying and documenting the lives of Black people in the southern US. She later went on to write several remarkable novels, including Their Eyes Were Watching God, which we discussed in Crash Course Literature. https://www.youtube.com/watch?v=4kF0U8kIMp4&t=1s

In which John Green teaches you about the beginnings of the American Revolution in a video titled The Seven Years War. Confusing? Maybe. John argues that the Seven Years' War, which is often called the French and Indian War in the US, laid a lot of the groundwork for the Revolution. More confusing? Why does this war have two names? Why were the French and Indians fighting each other? The Seven Years' war was actually a global war that went on for nine years. I think I'm having trouble making this clear. Anyway, the part of this global war that happened in North America was the French and Indian War. The French and Indian tribes were the force opposing the British, so that's the name that stuck. Let's get away from this war, as it makes my head hurt. Other stuff was going on in the colonies in the 18th century that primed the people for revolution. One was the Great Awakening. A religious revival was sweeping the country, introducing new ideas about religion and how it should be practiced. At the same time, thinkers like John Locke were rethinking the relationship between rulers and the ruled. So in this highly charged atmosphere, you can just imagine what would happen if the crown started trying to exert more control over the colonies. The colonists would probably just rise up, right? We'll see what happens next week.

We’re continuing our look at engineering materials with third main type of material that you’ll encounter as an engineer: polymers. They’re made of long, repeating chains of smaller molecules known as monomers and today we’ll explore their strange history of polymers and the things that contributed to how we use them today.

Well, it wouldn't be too long after we started developing Ecology that we would try to control the environment. In some ways this was helpful and likely prevented a lot of people from starving. But, there have been a few downsides.

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 about the Cold War, which was occasionally hot, but on average, it was just cool. In the sense of its temperature. It was by no means cool, man. After World War II, there were basically two big geopolitical powers left to divide up the world. And divide they did. The United States and the Soviet Union divvied up Europe in the aftermath of the war and then proceeded to spend the next 45 years fighting over the rest of the world. It was a great ideological struggle, with the US on the side of capitalism and profit, and the USSR pushing Communism, so-called. While both sides presented themselves as the good guy in this situation, the COLD reality is that there are no good guys. Both parties to the Cold War engaged in forcible regime changes, built up vast nuclear arsenals, and basically got up to dirty tricks. If you had to pick a bad guy though, we would point out that the USSR had no intention of bringing Laika the Cosmonaut Dog home alive. That poor dog never had a shot.

In which John Green teaches you about the Little Ice Age. The Little Ice Age was a period of global cooling that occurred from the 13th to the 19th centuries. This cooling was likely caused by a number of factors, including unusual solar activity and volcanic eruptions. The Little Ice Age greatly impacted human social orders, especially during the 17th century. When the climate changed, and the weather became unpredictable, the world changed profoundly. Poor harvests led to hunger, which led to even less productivity, which even resulted in violent upheaval in a lot of places. All this from a little change in the temperature? Definitely.

In which John teaches you about the Seven Years' War, which may have lasted nine years. Or as many as 23. It was a very confusing war. The Seven Years War was a global war, fought on five continents, which is kind of a lot. John focuses on the war as it happened in the Americas, Asia, and Africa. the "great" European powers were the primary combatants, but they fought just about everywhere. Of course, this being a history course, the outcomes of this war still resonate in our lives today. The Seven Years' war determined the direction of the British Empire and led pretty directly to the subject of Episode 28, the American Revolution.

But as usual with Crash Course, things were about to take a turn for the worse. John will teach you about the Charleston, the many Republican presidents of the 1920s, laissez-faire capitalism, jazz, consumer credit, the resurgent Klan, and all kinds of other stuff.

In the aftermath of the revolutions and upheaval in 18th and early 19th century Europe, there was a hunger for reform across the continent. Reformers like Robert Owen, Charles Fourier, and Auguste Comte proposed radical new ideas, and at the same time, regular people began to stand up and ask for greater equality, and a louder voice in how they were governed. Results were mixed, but a lot of the ideas that emerged during this time are still echoing in our world today.

This week on Crash Course Econ, Jacob and Adriene are talking about failure. Specifically, we're talking about market failures. When markets don't provide a good or service efficiently, that's a market failure. When markets fail, often governments step in to provide those services. Stuff like public education or military protection are good examples of market failures. So, what are some of the ways governments address, market failures? Well, it's funny you should ask, as we also talk about that in this episode. We'll get into taxes and subsidies and externalities and a bunch of other important stuff this week on Crash Course Econ.

In which John Green teaches you about the (English) colonies in what is now the United States. He covers the first permanent English colony at Jamestown, Virginia, the various theocracies in Massachusetts, the feudal kingdom in Maryland, and even a bit about the spooky lost colony at Roanoke Island. What were the English doing in America, anyway? Lots of stuff. In Virginia, the colonists were largely there to make money. In Maryland, the idea was to create a colony for Catholics who wanted to be serfs of the Lords Baltimore. In Massachusetts, the Pilgrims and Puritans came to America to find a place where they could freely persecute those who didn't share their beliefs. But there was a healthy profit motive in Massachusetts as well. Profits were thin at first, and so were the colonists. Trouble growing food and trouble with the Natives kept the early colonies from success. Before long though, the colonists started cultivating tobacco, which was a win for everyone involved if you ignore the lung cancer angle. So kick back, light up a smoke, and learn how America became profitable. DON'T SMOKE, THOUGH! THAT WAS A JOKE!

Today, we're going to take a closer look at how the oceans circulate by following the life of a discarded water bottle as it gets snagged in the North Pacific Garbage Patch. We'll talk about what causes the movement of water, called current, both near the surface and much deeper in the oceans, and we'll show how they follow similar (but not identical) paths to the winds. Ocean circulation plays a huge role in cycling vital nutrients within the seas and helps us transport goods on ships across the globe and it's up to us to protect it.

Clint Smith teaches you about one of the most famous writers, orators, and advocates of the 19th century, Frederick Douglass. Douglass was born in slavery, escaped to the North, and became one of the most influential people of his time. Douglass wrote about the experience of slavery in a way that captured the attention of people throughout the world, and his work and influence helped directly in the struggle to abolish slavery and achieve emancipation.

Clint's book, How the Word is Passed is available now! https://bookshop.org/a/3859/9780316492935

Well, it wouldn't be too long after we started developing Ecology that we would try to control the environment. In some ways this was helpful and likely prevented a lot of people from starving. But, there have been a few downsides.

In which John Green teaches you about one of the least funny subjects in history: slavery. John investigates when and where slavery originated, how it changed over the centuries, and how Europeans and colonists in the Americas arrived at the idea that people could own other people based on skin color.

Slavery has existed as long as humans have had civilization, but the Atlantic Slave Trade was the height, or depth, of dehumanizing, brutal, chattel slavery. American slavery ended less than 150 years ago. In some parts of the world, it is still going on. So how do we reconcile that with modern life? In a desperate attempt at comic relief, Boba Fett makes an appearance.
