Existentialism: Crash Course Philosophy #16
 
08:54
Now that we’ve left behind the philosophy of religion, it’s time to start exploring what other ways might exist to find meaning in the world. Today we explore essentialism and its response: existentialism. We’ll also learn about Jean-Paul Sartre and his ideas about how to find meaning in a meaningless world.

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. Turn on the captions. You'll like it.

The Heart, Part 1 - Under Pressure: Crash Course A&P #25
 
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.

Immune System, Part 1: Crash Course A&P #45
 
09:13
Our final episodes of Anatomy & Physiology explore the way your body keeps all that complex, intricate stuff alive and healthy -- your immune system. The immune system’s responses begin with physical barriers like skin and mucous membranes, and when they’re not enough, there are phagocytes -- the neutrophils and macrophages. It also features the awesomely named natural killer cells and the inflammatory response, and we'll explain how all of these elements work together to save the day if you happen to slip on a banana peel.

Muscles, Part 1 - Muscle Cells: Crash Course A&P #21
 
10:24
We're kicking off our exploration of muscles with a look at the complex and important relationship between actin and myosin. Your smooth, cardiac, and skeletal muscles create movement by contracting and releasing in a process called the sliding filament model. Your skeletal muscles are constructed like a rope made of bundles of protein fibers, and that the smallest strands are your actin and myosin myofilaments. Its their use of calcium and ATP that causes the binding and unbinding that makes sarcomeres contract and relax.

The Nucleus: Crash Course Chemistry #1
 
10:12
Hank does his best to convince us that chemistry is not torture, but is instead the amazing and beautiful science of stuff. Chemistry can tell us how three tiny particles - the proton, neutron and electron - come together in trillions of combinations to form ... everything. In this inaugural episode of Crash Course Chemistry, we start out with one of the biggest ideas in chemistry ever - stuff is made from atoms. More specifically, we learn about the properties of the nucleus and why they are important to defining what an atom actually is.

Aliens, Time Travel, and Dresden -Slaughterhouse-Five Part I: Crash Course Literature 212

You can directly support Crash Course at https://www.patreon.com/crashcourse 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 Kurt Vonnegut's most famous novel, Slaughterhouse-Five. Vonnegut wrote the book in the Vietnam era, and it closely mirrors his personal experiences in World War II, as long as you throw out the time travel and aliens and porn stars and stuff. Slaughterhouse-Five tells the story of Billy Pilgrim, a World War II veteran who was a prisoner of war, and survived the Battle of the Bulge and the fire-bombing of Dresden, goes home after the war, and has trouble adapting to civilian life (this is the part that's like Vonnegut's own experience). Billy Pilgrim has flashbacks to the war that he interprets as being "unstuck in time." He believes he's been abducted by aliens, and pretty much loses it. You'll learn a little about Vonnegut's life, quite a bit about Dresden, and probably more than you'd like about barbershop quartets as a metaphor for post traumatic stress.

Samurai, Daimyo, Matthew Perry, and Nationalism: Crash Course World History #34
 
11:53
In which John Green teaches you about Nationalism. Nationalism was everywhere in the 19th century, as people all over the world carved new nation-states out of old empires. Nationalist leaders changed the way people thought of themselves and the places they lived by reinventing education, military service, and the relationship between government and governed. In Japan, the traditional feudal society underwent a long transformation over the course of about 300 years to become a modern nation-state. John follows the course of Japanese history from the emergence of the Tokugawa Shogunate to the Meiji Restoration, and covers Nationalism in many other countries along the way. All this, plus a special guest appearance, plus the return of an old friend on a extra-special episode of Crash Course.

Visit http://dft.ba/-CCWHDVD to buy a set for your home or classroom. In which John Green teaches you about the economic malaise that beset the United States in the 1970s. A sort of perfect storm of events, it combined the continuing decline of America's manufacturing base and the oil shocks of 1973 and 1979, and brought about an stagnant economy, paired with high inflation. Economists with a flair for neologisms and portamenteau words called this "stagflation," and it made people miserable. Two presidential administrations were scuttled at least in part by these economic woes; both Gerald Ford and Jimmy Carter are considered failed presidents for many reasons, but largely because of an inability to improve the economy. (hint: In reality, no one person can materially change something as big as the world economy, even if they are president, but one person sure can make a handy scapegoat!) So, by and large, the 70s were a pretty terrible time in America economically, but at least the decade gave us Mr. Green. Crash Course World History is now available on DVD!

The Election of 1860 & the Road to Disunion: Crash Course US History #18
 
14:16
In which John Green teaches you about the election of 1860. As you may remember from last week, things were not great at this time in US history. The tensions between the North and South were rising, ultimately due to the single issue of slavery. The North wanted to abolish slavery, and the South wanted to continue on with it. It seemed like a war was inevitable, and it turns out that it was. But first the nation had to get through this election. You'll learn how the bloodshed in Kansas, and the truly awful Kansas-Nebraska Act led directly to the decrease in popularity of Stephen Douglas, the splitting of the Democratic party, and the unlikely victory of a relatively inexperienced politician from Illinois, Abraham Lincoln. Lincoln's election would lead directly to the secession of several southern states, and thus to the Civil War. John will teach you about all this, plus Dred Scott, Roger Taney, and John Brown. Support CrashCourse on Patreon: https://www.patreon.com/crashcourse 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.

12:11
Don't forget! Crash Course posters and t-shirts at http://store.dftba.com/collections/crashcourse 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.

Deep Time: Crash Course Astronomy #45

As we approach the end of Crash Course Astronomy, it’s time now to acknowledge that our Universe’s days are numbered. Stars will die out after a few trillion years, protons will decay and matter will dissolve after a thousand trillion trillion trillion years, black holes will evaporate after 10^92 years, and then all will be dark. But there is still hope that a new Universe will be born from it.

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: https://www.commonlit.org/texts/mccarthyism President Kennedy delivered an Inaugural Address during the height of the Cold War, initiating a space race: https://www.commonlit.org/texts/president-kennedy-s-inaugural-address President Kennedy also oversaw Cuba's emergence as a Cold War rival of the United States: https://www.commonlit.org/texts/cold-war-rivals-cuba-and-the-united-states

The 2008 Financial Crisis: Crash Course Economics #12
 
11:25
Today on Crash Course Economics, Adriene and Jacob talk about the 2008 financial crisis and the US Goverment's response to the troubles. So, all this starts with home mortgages, and the use of mortgages as an investment instrument. For years, it seemed like the US housing market would go up and up. Like a bubble or something. It turns out it was a bubble. But not the good kind. And the government response was...interesting. Anyway, why are you reading this? Watch the video!

Coal, Steam, and The Industrial Revolution: Crash Course World History #32

Mongols Shirts and Crash Course Posters! http://store.dftba.com/collections/crashcourse In which John Green wraps up revolutions month with what is arguably the most revolutionary of modern revolutions, the Industrial Revolution. While very few leaders were beheaded in the course of this one, it changed the lives of more people more dramatically than any of the political revolutions we've discussed. So, why did the Industrial Revolution happen around 1750 in the United Kingdom? Coal. Easily accessible coal, it turns out. All this, plus you'll finally learn the difference between James Watt and Thomas Newcomen, and will never again be caught telling people that your blender has a 900 Newcomen motor.

Decolonization and Nationalism Triumphant: Crash Course World History #40
 
12:49
READ THIS: THERE ARE TWO MORE VIDEOS IN THE WORLD HISTORY SERIES. You should also turn on the captions. You'll like them. In which John Green teaches you about the post-World War II breakup of most of the European empires. As you'll remember from previous installments of Crash Course, Europeans spent several centuries sailing around the world creating empires, despite the fact that most of the places they conquered were perfectly happy to carry on alone. After World War II, most of these empires collapsed. This is the story of those collapses. In most places, the end of empire was not orderly, and violence often ensued. While India was a (sort of) shining example of non-violent change, in places like The Congo, Egypt, Rwanda, Vietnam, Cambodia, and Laos, things didn't go smoothly at all. John brings you all this, plus pictures of Sea Monkeys. Sadly, they don't look anything like those awesome commercials in the comic books.
