  • Of Pentameter & Bear Baiting - Romeo & Juliet Part I: Crash Course English Literature #2

    12:42

    In which John Green examines Romeo & Juliet by William Shakespeare. John delves into the world of Bill Shakespeare's famous star-crossed lovers and examines what the play is about, its structure, and the context in which it was written. Have you ever wanted to know what iambic pentameter is? Then you should watch this video. Have you ever pondered what kind of people actually went to see a Shakespeare play in 1598? Watch this video. Were you aware that wherefore means why? Whether you were or not, watch this video. In Shakespeare's time, entertainment choices ranged from taking in a play to watching a restrained bear try to fight off a pack of dogs. Today on YouTube, our entertainment choices are just as wide-ranging. So you can either choose to watch the modern equivalent of bear baiting (another cinnamon challenge) or you can be edified and entertained by John and Crash Course. So wherefore are you reading this description instead of watching the video?

    Love or Lust? Romeo and Juliet Part II: Crash Course English Literature #3

    10:11

    In which John Green returns to William Shakespeare's Romeo and Juliet to explore the themes of true love, lust, and whether Romeo and Juliet were truly, deeply in love, or they were just a pair of impetuous teens. How exactly did Romeo manage to go from pining for Rosaline to marrying Juliet in 36 hours? Maybe they were impetuous teens who were ALSO deeply in love. John looks into how the structure and conventions of society in medieval Verona led to the star-crossed lovers' downfall. Along the way, you'll learn about courtly love, medieval responsibility to church, family and society, Chipotle burritos as a metaphor for true love, and even learn about literary sex. We may even tie in trapeze artists and Queen's Bohemian Rhapsody. You'll have to watch to find out.

  • Like Pale Gold - The Great Gatsby Part I: Crash Course English Literature #4

    11:43

    In which John Green explores F. Scott Fitzgerald's novel of the Jazz Age, The Great Gatsby. John introduces you to Nick Carraway, Jay Gatsby, Daisy and Tom Buchanan, and the other characters in the novel, and tries to look beyond the surface story to figure out what this thing is ABOUT. Set in the 1920's against a conflicted backdrop of prohibition and excess, The Great Gatsby takes a close look at the American Dream as it existed in Fitzgerald's time. It turns out, it had a lot to do with money and status, and it still does today. John will cover the rich symbolism of the novel, from the distant green light to the pale gold of wealth and decay. Also, Paris Hilton drops by.

  • Islam and Politics: Crash Course World History 216

    13:28

    In which John Green teaches you about how Islam has interacted with politics during it's history, and how it continues to do so today. Islamist movements are in the news a lot lately, but how did that happen. John will point out that Islam has alway been tied to political movements. Mohammed was not only a religious leader, he led an empire. So how did this lead to modern movements like ISIS? Islam has traditionally been a pretty egalitarian religion, and its scriptures value peace, so it is surprising in a lot of ways that such a violent fundamentalist movement would come out of it. What is a caliphate? What is a Caliph? John will teach you all about it. Take it easy in the comments, y'all. Be kind and respectful to each other.

    In which John Green teaches you about conflict in Israel and Palestine. This conflict is often cast as a long-term beef going back thousands of years, and rooted in a clash between religions. Well, that's not quite true. What is true is that the conflict is immensely complicated, and just about everyone in the world has an opinion about it.

    Language, Voice, and Holden Caulfield: The Catcher in the Rye Part 1

    10:52

    In which John Green examines JD Salinger's novel The Catcher in the Rye. John pulls out the old school literary criticism by examining the text itself rather than paying attention to the biographical or historical context of the novel (that's for next week). Listen, words matter. The Catcher in the Rye has managed to endure without a movie adaptation because a lot of its quality arises from the book's language. Find out how Holden's voice, his language, and his narrative technique combine to make the novel work.

  • 11 Things People with Depression Would Like You to Understand

    3:24

    A major depressive disorder — usually just called “depression” — is different than the “blues”. Someone experiencing depression is grappling with feelings of severe despair over an extended period of time. Almost every aspect of their life can be affected, including their emotions, physical health, relationships and work. For people with depression, it does not feel like there is a “light at the end of the tunnel” — there is just a long, dark tunnel.

    Understanding depression is a good step towards helping friends or family members who are having depression. Depression isn't as simple as feeling sad, its much more.

    It’s more than just getting bad grades.

    In which John Green teaches you about capitalism and socialism in a way that is sure to please commenters from both sides of the debate.

Learn about how we got from the British East India Company to iPhones and consumer culture in just a couple of hundred years. Stops along the way include the rise of industrial capitalism, mass production, disgruntled workers, Karl Marx, and the Socialist Beard. The socialist reactions to the ills of capitalism are covered as well, and John discusses some of the ideas of Karl Marx, and how they've been implemented or ignored in various socialist states.

    The Renaissance: Was it a Thing? - Crash Course World History #22

    11:33

    In which John Green teaches you about the European Renaissance. European learning changed the world in the 15th and 16th century, but was it a cultural revolution, or an evolution? We'd argue that any cultural shift that occurs over a couple of hundred years isn't too overwhelming to the people who live through it. In retrospect though, the cultural bloom in Europe during this time was pretty impressive. In addition to investigating what caused the Renaissance and who benefitted from the changes that occurred, John will tell you just how the Ninja Turtles got mixed up in all this.

  • Before I Got My Eye Put Out - The Poetry of Emily Dickinson: Crash Course English Lit #8

    10:11

    In which John Green concludes the Crash Course Literature mini-series with an examination of the poetry of Emily Dickinson. Sure, John explores the creepy biographical details of Dickinson's life, but he also gets into why her poems have remained relevant over the decades. John discusses Dickinson's language, the structure of her work, her cake recipes. He also talks about Dickinson's famously eccentric punctuation, which again ends up relating to her cake recipes. Also, Dickinson's coconut cake recipe is included. Also, here are links to some of the poems discussed in the video:

    The French Revolution: Crash Course World History #29

    11:55

    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.

    Communists, Nationalists, and Chinas Revolutions: Crash Course World History #37

    12:11

    Don't forget! Crash Course posters and t-shirts at

    In which John Green teaches you about China's Revolutions. While the rest of the world was off having a couple of World Wars, China was busily uprooting the dynastic system that had ruled there for millennia. Most revolutions have some degree of tumult associated with them, but China's 20th century revolutions were REALLY disruptive. In 1911 and 1912, Chinese nationalists brought 3000 years of dynastic rule to an end. China plunged into chaos as warlords staked out regions of the country for themselves. The nationalists and communists joined forces briefly to bring the nation back together under the Chinese Republic, and then they quickly split and started fighting the Chinese Civil War. The fight between nationalists and communists went on for decades, and was interrupted by an alliance to fight the invading Japanese during World War II. After the World War II ended, the Chinese Civil War was back on. Mao and the communists were ultimately victorious, and Chiang Kai-Shek ended up in Taiwan. And then it got weird. Mao spent years repeatedly trying to purify the Communist Party and build up the new People's Republic of China with Rectifications, Anti Campaigns, Five Year Plans. the Great Leap Forward, and the Cultural Revolution. These had mixed results, to say the least. John will cover all this and more in this week's Crash Course World History.

    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.

    In which John Green discusses the strange and mutually beneficial relationship between a republic, the citystate of Venice, and an Empire, the Ottomans--and how studying history can help you to be a better boyfriend and/or girlfriend. Together, the Ottoman Empire and Venice grew wealthy by facilitating trade: The Venetians had ships and nautical expertise; the Ottomans had access to many of the most valuable goods in the world, especially pepper and grain. Working together across cultural and religious divides, they both become very rich, and the Ottomans became one of the most powerful political entities in the world. We also discuss how economic realities can overcome religious and political differences (in this case between Muslims and Christians), the doges of Venice, the sultans of the Ottoman empire, the janissaries and so-called slave aristocracy of the Ottoman Empire, and how money and knowledge from the Islamic world helped fuel and fund the European Renaissance. Also, there's a They Might Be Giants joke.

    If you really want to read about Ottoman eunuchs (warning: it's explicit), here you go:

  • The Crusades - Pilgrimage or Holy War?: Crash Course World History #15

    11:33

    In which John Green teaches you about the Crusades embarked upon by European Christians in the 12th and 13th centuries. Our traditional perception of the Crusades as European Colonization thinly veiled in religion isn't quite right. John covers the First through the Fourth Crusades, telling you which were successful, which were well-intentioned yet ultimately destructive, and which were just plain crazy. Before you ask, no, he doesn't cover the Children's Crusade, in which children were provoked to gather for a Crusade, and then promptly sold into slavery by the organizers of said Crusade. While this story is charming, it turns out to be complete and utter hooey.

    Mongols T-Shirt:

    In which John Green teaches you, at long last, about the most exceptional bunch of empire-building nomads in the history of the world, the Mongols! How did the Mongols go from being a relatively small band of herders who occasionally engaged in some light hunting-gathering to being one of the most formidable fighting forces in the world? It turns out Genghis Khan was a pretty big part of it, but you probably already knew that. The more interesting questions might be, what kind of rulers were they, and what effect did their empire have on the world we know today? Find out, as John FINALLY teaches you about the Mongols.

  • HOW World War I Started: Crash Course World History 209

    9:10

    In which John Green teaches you about World War I and how it got started. Crash Course doesn't usually talk much about dates, but the way that things unfolded in July and August of 1914 are kind of important to understanding the Great War. You'll learn about Franz Ferdinand, Gavrilo Pincep, the Black Hand, and why the Serbian nationalists wanted to kill the poor Archduke. You'll also learn who mobilized first and who exactly started the war. Sort of. Actually there's no good answer to who started the war, but we give it a shot anyway.

    10:07

    Today we’re going to talk about on how we organize the data we use on our devices. You might remember last episode we walked through some sorting algorithms, but skipped over how the information actually got there in the first place! And it is this ability to store and access information in a structured and meaningful way that is crucial to programming. From strings, pointers, and nodes, to heaps, trees, and stacks get ready for an ARRAY of new terminology and concepts.

    Why Human Evolution Matters: Crash Course Big History 205

    11:30

    This week on Crash Course Big History, Emily is talking about process of human evolution, and the knack for innovation that has allowed humans to become so dominant on the Earth. Human innovation, and the ability to build on those innovations generation after generation is what makes humans different than other animals. Collective learning is enabled by our highly evolved and efficient ability to communicate with each other and pass on information. With great power, of course, comes great responsibility, and how we use this powerful tool has kind of a mixed track record.

    You can directly support Crash Course at Subscribe for as little as $0 to keep up with everything we're doing. Free is nice, but if you can afford to pay a little every month, it really helps us to continue producing this content.

    In which John Green teaches you about Harper Lee's famous (and only) novel, To Kill a Mockingbird. John will cover a bit about Harper Lee's personal life, (seeing as this novel has some autobiographical elements) and her long association with Truman Capote, who figures as a character in the book. You'll get an overview of the plot, and we'll talk a bit about Mockingbird as an example of bildungsroman (again(man, this description is heavy on parentheses)) and Southern Gothic, and look into the novel as a commentary on the racism and patriarchy of the Alabama in which Harper Lee grew up.

    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 was. 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.

    10:08

    Your heart gets a lot of attention from poets, songwriters, and storytellers, but today Hank's gonna tell you how it really works. The heart’s ventricles, atria, and valves create a pump that maintains both high and low pressure to circulate blood from the heart to the body through your arteries, and bring it back to the heart through your veins. You'll also learn what your blood pressure measurements mean when we talk about systolic and diastolic blood pressure.

  • Lord of the Flies: Crash Course Literature 305

    11:55

    This week, John i s talking about one of his least favorite novels, The Lord of the Flies by William Golding. Lord of the Flies is a novel of ideas, and John doesn't agree with the central idea of the novel, which diminished his enjoyment of the book. The central idea of the book is that everyone has evil in their hearts. Which we don't necessarily agree with. That said, it's a good read, and worth reading.

    In which you are introduced to the life and accomplishments of Alexander the Great, his empire, his horse Bucephalus, the empires that came after him, and the idea of Greatness. Is greatness a question of accomplishment, of impact, or are people great because the rest of us decide they're great?

    In which John Green teaches you about the Cold War, which was the decades long conflict between the USA and the USSR. The Cold War was called cold because of the lack of actual fighting, but this is inaccurate. There was plenty of fighting, from Korea to Viet Nam to Afghanistan, but we'll get into that stuff next week. This week we'll talk about how the Cold War started. In short it grew out of World War II. Basically, the Soviets occupied eastern Europe, and the US supported western Europe. This setup would spill across the world, with client states on both sides. It's all in the video. You should just watch it.

    Hey teachers and students - Check out CommonLit's free collection of reading passages and curriculum resources to learn more about the events of this episode. The Cold War spanned over four decades of American history, beginning with the paranoia of McCarthyism, a political witch hunt for communists:

Civil Rights were dominant, but the 60s also saw growth in the Women's Movement, the LGBT rights movement, the Latino rights movement, and the American Indian movement. Also, Americans began to pay a bit more attention to the environment. All this change happened against the backdrop of the Cold War and the Rise of Conservatism. It was just wild. John will teach you about sit-ins, Freedom Rides, The March on Washington, MLK, JFK, LBJ, and NOW. Man, that is a lot of initialisms. And one acronym.

    Algorithms are the sets of steps necessary to complete computation - they are at the heart of what our devices actually do. And this isn’t a new concept. Since the development of math itself algorithms have been needed to help us complete tasks more efficiently, but today we’re going to take a look a couple modern computing problems like sorting and graph search, and show how we’ve made them more efficient so you can more easily find cheap airfare or map directions to Winterfell... or like a restaurant or something.
