In which John Green teaches you about World War II, aka The Great Patriotic War, aka The Big One. So how did this war happen? And what does it mean? We've all learned the facts about World War II many times over, thanks to repeated classroom coverage, the History channel, and your grandfather (or maybe great-grandfather) showing you that Nazi bayonet he used to keep in his sock drawer and telling you a bunch of age-inappropriate stories about his harrowing war experiences. So, why did the Axis powers think forceful expansion was a good idea? (they were hungry). So why did this thing shake out in favor of the Allies? Hint: it has to do with the fact that it was a world war. Germany and Japan made some pretty serious strategic errors, such as invading Russia and attacking the United States, and those errors meant that pretty much the whole world was against them. So, find out how this worldwide alliance came together to stop the Axis expansion. All this, plus Canada finally gets the respectful treatment it deserves. Oh, and a warning: there are a few graphic images in this episode. Sensitive viewers may want to use caution, especially around the 9:15 mark.

In which John Green teaches you about European Imperialism in the 19th century. European powers started to create colonial empires way back in the 16th century, but businesses really took off in the 19th century, especially in Asia and Africa. During the 1800s, European powers carved out spheres of influence in China, India, and pretty much all of Africa. While all of the major (and some minor) powers in Europe participated in this new imperialism, England was by far the most dominant, once able to claim that the "sun never set on the British Empire." Also, they went to war for the right to continue to sell opium to the people of China. Twice. John will teach you how these empires managed to leverage the advances of the Industrial Revolution to build vast, wealth-generating empires. As it turns out, improved medicine, steam engines, and better guns were crucial in the 19th-century conquests. Also, the willingness to exploit and abuse the people and resources of so-called "primitive" nations was very helpful in the whole enterprise.

In which John Green teaches you about American involvement in World War I, which at the time was called the Great War. They didn't know there was going to be a second one, though they probably should have guessed, 'cause this one didn't wrap up very neatly. So, the United States stayed out of World War I at first, because Americans were in an isolationist mood in the early 20th century. That didn't last though, as the affronts piled up and drew the US into the war. Spoiler alert: the Lusitania was sunk two years before we joined the war, so that wasn't the sole cause for our jumping in. It was part of it though, as was the Zimmerman telegram, unrestricted submarine warfare, and our affinity for the Brits. You'll learn the war's effects on the home front, some of Woodrow Wilson's XIV Points, and just how the war ended up expanding the power of the government in Americans' lives.

Imagine if the only videos on YouTube were people looking for love. That could have been the world we lived in! Before it had 1.9 billion users per day, YouTube started as a video-based dating service, complete with the truly excellent catchphrase: “Tune in, Hook Up.”

The reason they didn’t flop is because they were willing to listen and fundamentally change their business when their original idea didn’t meet the needs of their market. They were clever observers and nimble enough to pivot.

In which John Green teaches you about the New Deal, which was president Franklin D. Roosevelt's plan to pull the United States out of the Great Depression of the 1930s. Did it work? Maybe. John will teach you about some of the most effective and some of the best-known programs of the New Deal. They weren't always the same thing. John will tell you who supported the New Deal, and who opposed it. He'll also get into how the New Deal changed the relationship between the government and citizens, and will even reveal just how the Depression ended. (hint: it was war spending)

Many organizations have made it their mission to expand the rights of Black Americans. The NAACP and the Urban League are examples of influential organizations with long histories. But a long history or extensive membership isn't always necessary to have an impact. Today, we'll learn about the Black Panthers. They were a relatively small, relatively short-lived political party that had an outsized impact on US history.

Today, Craig is going to give you an overview of civil rights and civil liberties. Often these terms are used interchangeably, but they are actually very different. Our civil liberties, contained in the Bill of Rights, once only protected us from the federal government, but slowly these liberties have been incorporated to protect us from the states. We’ll take a look at how this has happened and the supreme court cases that got us here.

We make small choices like what to eat for lunch, but we also have to set goals, pick a career, and decide how to invest our hard-earned money. It’s not easy! We don’t want to make a decision out of fear, rather than doing what’s best for us. And we don’t want to regret a big choice and dwell on the “what ifs” either.

So today, we’re going to take a step back, understand how to really look at the decisions we’re making, and learn what not to do when facing a difficult choice.

In this episode of Crash Course Physics, Shini sits down to talk about the realities of the apple story and how Newtonian Gravity is more than a little important.

How do astronomers make sense of the vastness of space? How do they study things so far away? Today Phil talks about distances, going back to early astronomy. Ancient Greeks were able to find the size of the Earth and from that the distance to and the sizes of the Moon and Sun. Once the Earth/Sun distance was found, parallax was used to find the distance to nearby stars, and that was bootstrapped using brightness to determine the distances to much farther stars.

In which John Green teaches you about Iran's Revolutions. Yes, revolutions plural. What was the the1979 Iranian Revolution about? It turns out that Iran has a pretty long history of unrest in order to put power in the hands of the people, and the most recent revolution in 1979 was, at least at first, not necessarily about creating an Islamic state. It certainly turned out to be about that, but it was initially just about people who wanted to get rid of an oppressive regime. Listen up as John teaches you about Iran's long history of revolution.

World War I was very hard on the Russian Empire. So hard, in fact, that it led to the end of the Russian Empire. As the global conflict ground on, Tsar Nicholas II faced increasing unrest at home. Today we'll learn about the Revolutions of 1917, the rise of Lenin, Trotsky, and the Bolsheviks, and the Reussian Civil War and the creation of the Soviet Union.

So far in this series, we've covered a lot of war, disease, climate disaster, and some more war. Well, prepare yourself for something a little more positive. This week, we're talking about the Enlightenment. In this video, you'll learn about the ideas of Voltaire, Rousseau, Montesquieu, Kant, Smith, Hume, and a bunch of other people whose ideas have been so impactful, they still influence the way we think about the world today.

During economic crises, marginalized communities are more susceptible to the harm and struggle that come with these downturns. Today we'll talk about the Great Depression, which lasted from 1929 until the US entered World War II. This depression profoundly changed the US economy, and we'll focus on how the depression impacted Black Americans.

Today we’re going to talk about recommender systems which form the backbone of so much of the content we see online from video recommendations on YouTube and Netflix to ads we see on Facebook, Twitter, and well, everywhere else. We’ll talk about their types of systems - content-based, social, and personalized recommendations - and take a closer look at what they're good at, but also why they often fail.
