    The Persians & Greeks: Crash Course World History #5

    Hi, I’m John Green, this is Crash Course World History, and today we’re going to do some legitimate comp. civ., for those of you into that kind of thing. Stan, I can’t help but feel that we have perhaps too many globes. That’s better. Today we’re going to learn about the horrible totalitarian Persians and the saintly, democracy-loving Greeks. But of course we already know this story — there were some wars in which no one wore any shirts, and everyone was reasonably fit. The Persians were bad; the Greeks were good. Socrates and Plato were awesome; the Persians didn’t even philosophize. The West is the Best; Go Team! Yeah,…

    Personality Disorders: Crash Course Psychology #34

    I can be smooth and charming and slick. I can make a very confident impression and it’s hard to leave me at a loss for words. Sometimes I find myself fantasizing about unlimited success and power, and beauty. I have repeatedly used deceit to cheat, con, or defraud others for my personal gain. To be honest, I don’t have much concern for the feelings of other people, or their suffering. Doesn’t sound like the Hank you know, does it? These are all statements from the Self-Assessment measure for Personality Disorders, that lets patients describe themselves, ranking each statement in terms of how accurate they think it is. To be honest,…

    Aquinas & the Cosmological Arguments: Crash Course Philosophy #10

    Crash Course Philosophy is brought to you by Squarespace. Squarespace: share your passion with the world. Nothing gets people talking like proving the existence of God — just look at the comments on our last video. And that is what Anselm of Canterbury did. He claimed, in the 11th century, to have come up with deductive proof of God’s existence, through what we now know as the ontological argument. And, if there was such a thing as a social network of medieval Christian philosophers back then, it was positively abuzz with the news. For a long time. Because, almost 200 years later, Italian theologian and philosopher Thomas Aquinas encountered Anselm’s…

    Political Ideology: Crash Course Government and Politics #35

    Hi, I’m Craig, and this is Crash Course Government and Politics. And today, we’re gonna get personal. Not personal in the sense that I’m gonna tell you I’m a bed wetter cause I’m not…gonna tell you that. We’re gonna talk about people’s personal political views and where they come from. This is what political scientists sometimes call Political Socialization. But before we get into the forces that help create our political outlooks, we should probably define what political ideologies look like in America. [Theme Music] In America, there are a number of ways people characterize themselves politically. Typically, they identify with a political party, although as we’ll see when we…

    Introduction: Crash Course U.S. Government and Politics

    Hi, I’m Craig. I’m not John Green, but I do have patches on my elbows, so I seem smart. And this is Crash Course Government and Politics, a new show, hurray! Why are fireworks legal or illegal? We might find out. Will we find out Stan? Anyway, I have a question for you. Have you ever wondered where your tax dollars go or why people complain about it so much? Or who pays for the highway that runs past your house? Or why you use the textbooks you use in science class? Or why you need a license to drive, or to hunt or to fish or to become a…

    Crash Course Navigating Digital Information Preview

    Hi, my name is John Green… In a few weeks we will begin a 10-episode series on Navigating Digital Information, which probably sounds boring. We thought it about calling something else–Crash Course Saving the Internet from Itself, Crash Course Oh My God This Virtual Place Is On Fire, Crash Course Maybe We Should Go Back to Trusting Experts, et cetera. But we ended up calling it Crash Course Navigating Digital Information because that is what we are actually going to try to learn how to do together. And I say together because I am not particularly good at navigating digital information. Like a lot of you, I’ve read entire stories…

    Data & Infographics: Crash Course Navigating Digital Information #8

    Hi I’m John Green. This is Crash Course: Navigating Digital Information. So what would you say if I told you that 90% of people polled say that they love Crash Course and think we offer consistently reliable and accurate information on the most important educational topics. You might say, “Hold on. I’ve seen the comments. That can’t be true.” And you’d be kind of right, but I would also be kind of right, because I did do that survey, and 90% of people did agree with those positive statements about Crash Course–but I surveyed 10 people who work on Crash Course. It would’ve been 100%, but Stan said, “Is this…

    Christianity from Judaism to Constantine: Crash Course World History #11

    Hi there my name’s John Green; this is Crash Course World History and today we’re going to talk about Jesus. So this is a Roman coin from around the time Jesus was born in the Roman Empire, and it calls Augustus, the emperor, the son of God. So let’s just state at the outset that in 4 BCE, being the son of God, or at least being the son of a god was not such an unusual thing. But a poor Jew being the son of God — that was news. [Theme Music] Any understanding of Christianity has to start with Judaism, because Jesus was born a Jew, and he…

    Personal Identity: Crash Course Philosophy #19

    Crash Course Philosophy is brought to you by Squarespace. Squarespace: share your passion with the world. Who is The Doctor? Is it this guy? Or this one? How about him? As any good Whovian knows, the answer is yes, all of them. But, also, wait: No. In the show Doctor Who, each incarnation of The Doctor has a completely different body, different mannerisms, likes and dislikes and, to some extent, memories. So… how are they all The Doctor? Science fiction is great at giving us scenarios to grapple with that seem far-out and only barely possible. But when you think about it, the issue of Who is Who isn’t that…

    Educational Games: Crash Course Games #15

    Hi, I’m André Meadows and this is Crash Course Games. We’ve looked at many types of games in this series, from card games to board games to video games, and all of these games share one common characteristic: They require learning. They teach us the rules of the game world, otherwise we wouldn’t be able to play them. Even a simple game like Rock Paper Scissors requires the players to learn the rules to participate. But players can also go beyond these basic rules by learning strategies and techniques to increase the likelihood of a win. So this might mean figuring out which combination of buttons will produce Sub-Zero’s Arctic…
