    What is sociology???

    5:05

    I applied for a PGCE course and I had to make a video explaining to 16 year olds, What is sociology? It would have been better if I'd used a BBC-circa-1948 voice, but I didn't have the guts.

  • SOCIOLOGY - Émile Durkheim

    7:48

    Emile Durkheim was a French 19th century sociologist who focused on what modern capitalism does to our minds - and concluded that it might, quite literally, be driving us to an early grave. Please subscribe here:

  • Integrated Circuits & Moore’s Law: Crash Course Computer Science #17

    13:50

    Get your first two months of Curiosity Stream free by going to and using the promo code “crashcourse”.

    So you may have heard of Moore's Law and while it isn't truly a law it has pretty closely estimated a trend we've seen in the advancement of computing technologies. Moore's Law states that we'll see approximately a 2x increase in transistors in the same space every two years, and while this may not be true for much longer, it has dictated the advancements we've seen since the introduction of transistors in the mid 1950s. So today we're going to talk about those improvements in hardware that made this possible - starting with the third generation of computing and integrated circuits (or ICs) and printed circuit boards (or PCBs). But as these technologies advanced a newer manufacturing process would bring us to the nanoscale manufacturing we have today - photolithography.

  • Earth Mothers and Rebellious Sons - Creation Part 3: Crash Course Mythology #4

    12:07

    So, we’re still talking about sex this week, but we’re talking about Earth Mothers and their children. We'll start with Gaia, and her son Kronos, who had a classic childhood rebellion, and castrated his father. We'll also get into Kronos’s son Zeus, who would go on to dethrone his father. We’ll talk about Norse mythology, too, and look at the family that created the world, and worked together to make people.

  • Representing Numbers and Letters with Binary: Crash Course Computer Science #4

    10:46

    Please take our PBS Digital Studios Survey!

    Today, we’re going to take a look at how computers use a stream of 1s and 0s to represent all of our data - from our text messages and photos to music and webpages. We’re going to focus on how these binary values are used to represent numbers and letters, and discuss how our need to perform operations on larger and more complex values brought us from our 8-bit video games to beautiful Instagram photos, and from unreadable garbled text in our emails to a universal language encoding scheme.

  • Boolean Logic & Logic Gates: Crash Course Computer Science #3

    10:07

    Today, Carrie Anne is going to take a look at how those transistors we talked about last episode can be used to perform complex actions. With the just two states, on and off, the flow of electricity can be used to perform a number of logical operations, which are guided by a branch of mathematics called Boolean Algebra. We’re going to focus on three fundamental operations - NOT, AND, and OR - and show how they were created in a series of really useful circuits. And its these simple electrical circuits that lay the groundwork for our much more complex machines.

    *CORRECTION* AT 1:27 the graph says Quinary System but then the graph shows 10 possible states - which is actually decimal. Technically, there should be only 5 possible values there, but the overall concept is still the same.

    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.

  • Émile Durkheim on Suicide & Society: Crash Course Sociology #5

    9:37

    Now that we’ve talked a little bit about how sociology works, it’s time to start exploring some of the ideas of the discipline’s founders. First up: Émile Durkheim. We’ll explain the concept of social facts and how Durkheim framed sociology as a science. We’ll introduce the idea of common consciousness and how Durkheim believed it binds society together. We’ll also talk about Durkheim’s studies on suicide and how he applied his concepts to a specific social problem.

    Symbols, Values & Norms: Crash Course Sociology #10

    9:33

    What exactly is culture? This week we’re going to try to answer that, and explain the difference between material and non-material culture. We’ll look at three things that make up culture: symbols, values and beliefs, and norms. We’ll explore Sapir-Whorf hypothesis (and some of its problems) and how language influences culture. Finally, we’ll talk about the three types of norms – folkways, mores, and taboos – which govern our daily life.

    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.

    9:41

    What is culture? How do we define it and how does it change? We’ll explore different categories of culture, like low culture, high culture, and sub-cultures. We'll also revisit our founding theories to consider both a structural functionalist and a conflict theory perspective on what cultures mean for society.

    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.

    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.

  • 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.

    World War II, A War for Resources: Crash Course World History #220

    In which John Green teaches you about World War II, and some of the causes behind the war. In a lot of ways, WWII was about resources, and especially about food. The expansionist aggression of both Germany and Japan were in a lot of ways about resources. There were other reasons, to be sure, but the idea that the Axis needed more food can't be ignored.

We’ll explore anticipatory socialization from your family, the “hidden curriculum” in schools, peer groups, the role of media in socialization, and we’ll discuss total institutions and how they can act as a form of re-socialization.

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

    11:05

    Mongols Shirts and Crash Course Posters!

    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.

    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.

John is going to try to get the facts across in under 13 minutes.

    Crash Course World History #7

    discussing the complicated relationship between the Confucian scholars
    who wrote Chinese history and the emperors (and empress) who made it.
    Included is a brief introduction to all the dynasties in Chinese
    history and an introduction to Confucius and the Confucian emphasis on
    filial piety, the role the mandate of heaven played in organizing
    China, and how China became the first modern state.

    How and Why We Read: Crash Course English Literature #1

    7:00

    In which John Green kicks off the Crash Course Literature mini series with a reasonable set of questions. Why do we read? What's the point of reading critically. John will argue that reading is about effectively communicating with other people. Unlike a direct communication though, the writer has to communicate with a stranger, through time and space, with only dry dead words on a page. So how's that going to work? Find out with Crash Course Literature! Also, readers are empowered during the open letter, so that's pretty cool.

    The Reading List!

    Romeo and Juliet by William Shakespeare:

    The Great Gatsby by F. Scott Fitzgerald:

    Catcher in the Rye:

    African Pantheons and the Orishas: Crash Course Mythology #11

    11:11

    So, today we’re talking about African Pantheons. Now, you might say, that’s ridiculous. Africa isn’t a single place with a single pantheon, and we’d be fools to try and cover all that in an eleven minute video. You’d be right. Instead we’re going to focus on Yoruba religion from west Africa, and the Orishas that populate Yoruba stories. The many, many Orishas cover all aspects of life, and can be pretty specialized. We’re going to focus on a dozen or so.

    Why Cosmic Evolution Matters: Crash Course Big History #201

    Crash Course Big History is back! It turns out, we couldn't tell all of the 13.8 billion years of the history of the universe in 10 Crash Course Episodes. So, Big History host Emily Graslie has returned to add 6 more episodes that look at why the stuff we studied in Big History matter. Today, we're starting with a look at why Cosmic Evolution matters. What exactly does the process of the big bang, the formation of stars, and the birth of planets mean to our lives? Let's find out together.

    The Black Legend, Native Americans, and Spaniards: Crash Course US History #1

    11:20

    In which John Green kicks off Crash Course US History! Why, you may ask, are we covering US History, and not more World History, or the history of some other country, or the very specific history of your home region? Well, the reasons are many. But, like it or not, the United States has probably meddled in your country to some degree in the last 236 years or so, and that means US History is relevant all over the world. In episode 1, John talks about the Native Americans who lived in what is now the US prior to European contact. This is a history class, not archaeology, so we're mainly going to cover written history. That means we start with the first sustained European settlement in North America, and that means the Spanish. The Spanish have a long history with the natives of the Americas, and not all of it was positive. The Spanish were definitely not peaceful colonizers, but what colonizers are peaceful? Colonization pretty much always results in an antagonistic relationship with the locals. John teaches you about early Spanish explorers, settlements, and what happened when they didn't get along with the indigenous people. The story of their rocky relations has been called the Black Legend. Which is not a positive legend.

  • Floods in the Ancient Near East: Crash Course Mythology #16

    10:23

    This week on Crash Course mythology, Mike is talking to you about floods. You may have heard the story of Noah and the Ark from the Bible, but that is not the only deluge story humans tell. It's a common thing across culture. You could say the study of mythology is...flooded with them. Sorry. We'll be looking at floods from Mesopotamia from the Epic of Gilgamesh, and a flood story from the Zoroastrian tradition. And we'll look at a Roman flood story from Ovid's metamorphosis. It's a deluge of flood stories!

    Most of the stories and quotations in this episode are adapted from David Leeming's Mythology textbook, The World of Myth.

    The wisdom of sociology: Sam Richards at TEDxLacador

    14:00

    How can an academic discipline like Sociology be life changing? This talk suggests one way by exploring how sociologists teach us to re-imagine our personal problems and ourselves. In the end, we learn that even in our most private and seemingly isolated moments, we may be more connected to others than we realize.

    His unique ability to connect with students along with his innovative use of technology in the classroom makes Sam Richards a very popular Sociology professor in the United States. Every semester over 750 students at Penn State University take his class on race and ethnic relations, the largest course on this subject in the world. He creates an active learning space where he addresses with humor and courage the very questions that most of us choose to avoid. Sam is also a co-founder of Penn State's World in Conversation Center. Every year, thousands of students from around the world participate in the Center's mission to bring conflict into collaboration through peer-facilitated dialogue.

    About TEDx, x = independently organized event

    In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience. At a TEDx event, TEDTalks video and live speakers combine to spark deep discussion and connection in a small group. These local, self-organized events are branded TEDx, where x = independently organized TED event. The TED Conference provides general guidance for the TEDx program, but individual TEDx events are self-organized.* (*Subject to certain rules and regulations)

  • Early Computing: Crash Course Computer Science #1

    11:53

    Hello, world! Welcome to Crash Course Computer Science! So today, we’re going to take a look at computing’s origins, because even though our digital computers are relatively new, the need for computation is not. Since the start of civilization itself, humans have had an increasing need for special devices to help manage laborious tasks, and as the scale of society continued to grow, these computational devices began to play a crucial role in amplifying our mental abilities. From the abacus and astrolabe to the difference engine and tabulating machine, we’ve come a long way to satisfying this increasing need, and in the process completely transformed commerce, government, and daily life.

    Today on Crash Course Mythology we’re starting in on creation stories. This week, we’ll focus on the creation of the universe out of nothing, or Ex Nihlio creation. Basically, a god decides to make a universe out of nothing. We’ll look at the Genesis story (which has nothing to do with Peter Gabriel or Phil Collins), a Mayan creation tale, a Kono story of the beginning, and we’ll even look at the Big Bang.

    Imperialism: Crash Course World History #35

    13:46

    In which John Green teaches you about European Imperialism in the 19th century. European powers started to create colonial empires way back in the 16th century, but businesses really took off in the 19th century, especially in Asia and Africa. During the 1800s, European powers carved out spheres of influence in China, India, and pretty much all of Africa. While all of the major (and some minor) powers in Europe participated in this new imperialism, England was by far the most dominant, once able to claim that the sun never set on the British Empire. Also, they went to war for the right to continue to sell opium to the people of China. Twice. John will teach you how these empires managed to leverage the advances of the Industrial Revolution to build vast, wealth-generating empires. As it turns out, improved medicine, steam engines, and better guns were crucial in the 19th century conquests. Also, the willingness to exploit and abuse the people and resources of so-called primitive nations was very helpful in the whole enterprise.

  • Archetypes and Male Divinities: Crash Course Mythology #15

    11:46

    This week on Crash Course Mythology, Mike is teaching you about the archetypes that are often associated with male divinities. We’re going to talk about Fathers & Sons, Kings & Judges, Saviors & Sages, Shamans, Tricksters, and Lords of Destruction. Along the way, we’ll look at the story of Hwaning, Hwanung, and Dangun from the Korean peninsula, and we’ll learn about Arjuna and all the help he got from Krishna. We’ll also touch on a ton of other myths from around the world. These things play out this way all the time, man.
