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.

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 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.

Once again, literature comes down to just what it means to be human. John will review the plot, and take you through a couple of different critical readings of the novel, and will discuss the final disposition of Percy Shelley's heart.

The French Revolution: Crash Course World History #29

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.

Congressional Committees: Crash Course Government and Politics #7
 
08:28
This week Craig Benzine clears up the role of committees in Congress. We’ll talk about standing committees, joint committees, conference committees, and caucuses (and not the candidate-choosing kinds) as well as the staff agencies that help advise these committees and congresspeople. As most bills never even make it to the house and senate floors for a vote, the role of committees, and their respective chairpersons as gatekeeper is pretty important. There’s a lot to demystify here as the legislative process can seem pretty arcane at times, but the model, at least in theory, helps Congress run more efficiently.

Their key anatomical differences - where nerve fibers originate and where their ganglia are located - drive their distinct anatomical functions, making your sympathetic nervous system the "fight or flight" while your parasympathetic nervous system is for "resting and digesting." -- Table of Contents The Basic Two-Part System of the Autonomic Nervous System 0:48 Sympathetic Nervous System 2:33 Parasympathetic Nervous System 2:54 Their Nerve Fibers Originate in Different Parts of the Body 3:22 Sympathetic Ganglia Are Close to the Spinal Cord 4:36 Parasympathetic Ganglia Are Close to Their Effectors 4:59 *** Crash Course is now on Patreon!

What is Philosophy?: Crash Course Philosophy #1
 
10:35
Today Hank begins to teach you about Philosophy by discussing the historical origins of philosophy in ancient Greece, and its three main divisions: metaphysics, epistemology, and value theory. He will also introduce logic, and how you’re going to use it to understand and critically evaluate a whole host of different worldviews throughout this course. And also, hopefully, the rest of your life. -- Images and video via VideoBlocks or Wikimedia Commons, licensed under Creative Commons by 4.0: https://creativecommons.org/licenses/by/4.0/ -- Produced in collaboration with PBS Digital Studios: http://youtube.com/pbsdigitalstudios Crash Course Philosophy is sponsored by Squarespace. http://www.squarespace.com/crashcourse -- Want to find Crash Course elsewhere on the internet?

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!

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.

In which John Green teaches you about one of the least funny subjects in history: slavery. John investigates when and where slavery originated, how it changed over the centuries, and how Europeans and colonists in the Americas arrived at the idea that people could own other people based on skin color. Slavery has existed as long as humans have had civilization, but the Atlantic Slave Trade was the height, or depth, of dehumanizing, brutal, chattel slavery. American slavery ended less than 150 years ago. In some parts of the world, it is still going on. So how do we reconcile that with modern life?

Globalization I - The Upside: Crash Course World History #41
 
11:51
In which John Green teaches you about globalization, a subject so epic, so, um, global, it requires two videos. In this video, John follows the surprisingly complex path of t-shirt as it criss-crosses the world before coming to rest on your doorstep, and eventually in your dresser. (Unless you're one of those people who never puts their laundry away and lives out of a laundry basket. If that's the case, shame on you.) Anyway, the story of the t-shirt and its manufacture in far-flung places like China, Guatemala, and India is a microcosm of what's going on in the global economy. Globalization is a bit of a mixed bag, and there have definitely been winners and losers along the way. In this episode John will talk about some of the benefits that have come along with it. Next week, he'll get into some of the less-positive side effects of globalization. Also, you should turn on the captions.

Venice and the Ottoman Empire: Crash Course World History #19
 
10:12
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.

Find out how Caesar came to rule the empire, what led to him getting stabbed 23 times on the floor of the senate, and what happened in the scramble for power after his assassination. John covers Rome's transition from city-state to dominant force in the Mediterranean in less than 12 minutes. Well, Rome's expansion took hundreds of years, he just explains it in under 12 minutes. The senate, the people, Rome, the caesarian section, the Julian calendar and our old friend Pompey all make appearances, but NOT the Caesar Salad, as Julius had nothing to do with it.

Metaethics: Crash Course Philosophy #32
 
09:34
We begin our unit on ethics with a look at metaethics. Hank explains three forms of moral realism – moral absolutism, and cultural relativism, including the difference between descriptive and normative cultural relativism – and moral subjectivism, which is a form of moral antirealism. Finally, we’ll introduce the concept of an ethical theory.

USA vs USSR Fight! The Cold War: Crash Course World History #39
 
12:16
In which John Green teaches you about the Cold War, which was occasionally hot, but on average, it was just cool. In the sense of its temperature. It was by no means cool, man. After World War II, there were basically two big geopolitical powers left to divide up the world. And divide they did. The United States and the Soviet Union divvied up Europe in the aftermath of the war, and then proceeded to spend the next 45 years fighting over the rest of the world. It was the great ideological struggle, with the US on the side of capitalism and profit, and the USSR pushing Communism, so-called. While both sides presented themselves as the good guy in this situation, the reality is that there are no good guys. Both parties to the Cold War engaged in forcible regime changes, built up vast nuclear arsenals, and basically got up to dirty tricks. If you had to pick a bad guy though, I would point out that the USSR had no intention of bringing Laika the Cosmonaut Dog home alive. That poor dog never had a shot. Sorry to disappoint, but the economist t-shirts are not a real product. Thanks to Raoul Meyer for the YUGOGAL photo.

Low Mass Stars: Crash Course Astronomy #29
 
12:03
Today we are talking about the life -- and death -- of stars. Low mass stars live a long time, fusing all their hydrogen into helium over a trillion years. More massive stars like the Sun live shorter lives. They fuse hydrogen into helium, and eventually helium into carbon (and also some oxygen and neon). When this happens they expand, get brighter, and cool off, becoming red giants. They lose most of their mass, exposing their cores, and then cool off over many billions of years.

Gerrymandering: Crash Course Government and Politics #37
 
07:58
Today Craig is going to talk about a topic that makes voters and politicians alike ANGRY! We're going to talk about Gerrymandering - that is the process in which voting districts are redrawn in a way to favor one party during elections. As you'll see, this is why election outcomes on Census years (which tend to be when districts are redrawn) are a really big deal. So we'll talk about how some of these cockamamie voting districts come to be and explain how Gerrymandering can affect the outcomes (and misrepresent voters) during elections. But even with all these rage-inducing and bizarre district maps, it's important to remember that it isn't ALL political scheming, but also a reflection of the tendency for Democrats to live in urban areas.

White Dwarfs & Planetary Nebulae: Crash Course Astronomy #30
 
11:10
Today Phil follows up last week’s look at the death of low mass stars with what comes next: a white dwarf. White dwarfs are incredibly hot and dense objects roughly the size of Earth. They also can form planetary nebulae: huge, intricately detailed objects created when the wind blown from the dying stars is lit up by the central white dwarf. They only last a few millennia. The Sun probably won’t form one, but higher mass stars do. -- Table of Contents When low mass stars die they form white dwarfs 0:54 White dwarfs are roughly the size of Earth 2:16 Cloudy with a chance of Planetary Nebulae 3:59 Life Span 9:06 -- PBS Digital Studios: http://youtube.com/pbsdigitalstudios Follow Phil on Twitter: https://twitter.com/badastronomer Want to find Crash Course elsewhere on the internet?

In the late 19th and early 20th century in America, there was a sense that things could be improved upon. A sense that reforms should be enacted. A sense that progress should be made. As a result, we got the Progressive Era, which has very little to do with automobile insurance, but a little to do with automobiles. All this overlapped with the Gilded Age, and is a little confusing, but here we have it. Basically, people were trying to solve some of the social problems that came with the benefits of industrial capitalism. To oversimplify, there was a competition between the corporations' desire to keep wages low and workers' desire to have a decent life. Improving food safety, reducing child labor, and unions were all on the agenda in the Progressive Era. While progress was being made, and people were becoming more free, these gains were not equally distributed. Jim Crow laws were put in place in the south, and immigrant rights were restricted as well. So once again on Crash Course, things aren't so simple. 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 Progressive Era was marked by rapid reactions to the Gilded Age: https://www.commonlit.org/texts/the-progressive-era Literature such as The Jungle revealed the horrifying conditions of factory industries, one of several which were overhauled with new progressive regulations: https://www.commonlit.org/texts/excerpt-from-the-jungle
