  • The French Revolution: Crash Course World History #29

    In which John Green examines the French Revolution, and gets into how and why it differed from the American Revolution. Was it the serial authoritarian regimes? The guillotine? The Reign of Terror? All of this and more contributed to the French Revolution not being quite as revolutionary as it could have been. France endured multiple constitutions, the heads of heads of state literally rolled, and then they ended up with a megalomaniacal little emperor by the name of Napoleon. But how did all of this change the world, and how did it lead to other, more successful revolutions around the world? Watch this video and find out. Spoiler alert: Marie Antoinette never said, "Let them eat cake." Sorry.

  • Democracy, Authoritarian Capitalism, and China: Crash Course World History 230

    In which John Green teaches you about the end of World History, and the end of the world as we know it, kind of. For the last hundred years or so, it seemed that one important ingredient for running an economically successful country was a western-style democratic government. All evidence pointed to the idea that capitalist representative democracies made for the best economic outcomes. It turns out that isn't the only way to succeed. In the last 40 years or so, authoritarian capitalism as it's practiced in places like China and Singapore has been working really, really well. John is going to look at these systems and talk about why they work, and he's even going to make a few predictions about the future. Also, thanks for watching this series. It has been amazingly fun to create, and we appreciate all of you.

  • Tea, Taxes, and The American Revolution: Crash Course World History #28

    In which John Green teaches you about the American Revolution and the American Revolutionary War, which it turns out were two different things. John goes over the issues and events that precipitated rebellion in Britain's American colonies, and he also explores the ideas that laid the groundwork for the new American democracy. Find out how the tax bill from the Seven Years' War fomented an uprising, how the Enlightenment influenced the Founding Fathers, and who were the winners and losers in this conflict. (hint: many of the people living in the Colonies ended up losers) The Revolution purportedly brought freedom and equality to the Thirteen Colonies, but they weren't equally distributed. Also, you'll learn about America's love affair with commemorative ceramics and what happens when rich white guys take the reins from rich white guys and put together a society of, by, and for rich white guys.

    Introduction: The American Revolution 00:00
    Tensions Rising: The Stamp Act, Townsend Act, and Boston Massacre 0:52
    An Open Letter to Tea 2:25

  • Amines: Crash Course Organic Chemistry #46

    Did you know that the fishier a fish smells, the longer it’s been out of the water? This is due to a chemical called trimethylamine, which is an amine, the class of organic compounds we’re discussing in this episode! Although they tend to be pretty stinky, amines are important in many fields like biochemistry, medicine, and agriculture. In this episode of Crash Course Organic Chemistry, we’ll explore amine formation and basicity, and revisit some old friends, imines and enamines!

  • Why Do Outbreaks Affect People Unequally? Crash Course Outbreak Science #4

    We’re all susceptible to infectious disease of some kind or other, but not everyone is equally likely to be the victim of an outbreak. The fact is, inequalities both between and within communities mean that some people are at higher risk than others. In this episode of Crash Course Outbreak Science, we’ll look deeper at the factors that lead to this uneven distribution of outbreaks.

    This episode of Crash Course Outbreak Science was produced by Complexly in partnership with Operation Outbreak and the Sabeti Lab at the Broad Institute of MIT and Harvard—with generous support from the Gordon and Betty Moore Foundation.
