  • How Can Cooperation End an Outbreak? Crash Course Outbreak Science #11

    In 1959, the WHO set out to eradicate smallpox, an ambitious goal that was achieved by 1980. But this goal wouldn't have been possible without coordination on all levels of society. In this episode of Crash Course Outbreak Science, we'll look at cooperation on the individual, community, and national scale and see how by working together we can improve outcomes during an outbreak, prevent future outbreaks, and even eradicate disease.

    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.

  • Ghosts, Murder, and More Murder - Hamlet Part 1: Crash Course Literature 203

    In which John Green teaches you about Hamlet, William Shakespeare's longest and most-performed play. People love Hamlet. The play that is, not necessarily the character. Hamlet is a Tragedy with a capital T (I guess I don't have to point that out since you can see clearly in the text that the T was capitalized). By Tragedy, I mean virtually everyone dies at the end. John will talk a little bit about the history of the play and the different versions of it that have appeared in the centuries since it was written. You'll also learn about some of the big themes in the play, get a brief plot overview, and the all-important connections between Prince Hamlet and Simba, the Lion King. Seriously though, The Lion King is totally just a Hamlet musical with animals instead of people.

  • The Plate Tectonics Revolution: Crash Course Geography #19

    Today we're going to tell the story of a quiet revolution in the 1960s that shifted our entire understanding of how the Earth works. We currently believe that the Earth's broken outer shell rises from the mantle and folds back in - kind of like a dance of creative destruction and reconstruction - giving us our continents and oceans, mountains and valleys, volcanoes, and earthquakes. And it would take a group of scientists all over the world to get us this grand unifying theory of plate tectonics.

  • Fate, Family, and Oedipus Rex: Crash Course Literature 202

    In which John Green teaches you about one of the least family-friendly family dramas in the history of family dramas, Oedipus Rex. Sophocles' most famous play sees its main character, who seems like he's got it all together, find out that he's killed his father, married his mother, had a bunch of incest children, and brought a plague down on his adopted hometown. He doesn't take this news well. John touches on all the classic Oedipus themes, including hamartia, fate, and the wrath of the gods, and even gets into some Freud, although Oedipus was notably not a sufferer of an Oedipus complex. In any case get ready for mystery, incest, bird entrails, and self-inflicted blindness. Very dramatic.
