This is the story of how a young Englishman named William Shakespeare stormed London's theater scene in the late 16th century, and wrote a bunch of plays and poems that have had pretty good staying power. We'll learn about Shakespeare's beginnings, his family, and how he broke into theater

Today we’re talking all about fluid mechanics! We’ll look at different scales that we work with as engineers, mass and energy transfers, the no-slip condition, stress and strain, Newton’s law of viscosity, Reynold’s number, and more!

In our final episode of Crash Course Sociology we are going to talk about what the health care system in the US looks like, the five A’s of health care accessibility, and a couple of contributing factors to the affordability of health care: fee for service care and the structure of our health insurance system which encourage higher spending.

We've talked a lot about modeling data and making inferences about it, but today we're going to look towards the future at how machine learning is being used to build models to predict future outcomes. We'll discuss three popular types of supervised machine learning models: Logistic Regression, Linear discriminant Analysis (or LDA) and K Nearest Neighbors (or KNN). For a broader overview of machine learning, check out our episode in Crash Course Computer Science!

It's a Scandinavian grudge match on Crash Course Theater. We're looking at a couple of the key movements in European theater that deeply influenced the modern theater of today. We'll take a close look at two of the most radical and influential European playwrights of the 19th century, who just happened to be mortal enemies. Henrik Ibsen of Norway, and Swede August Strindberg reshaped theater, between bouts of hating each other.

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 Irish Renaissance in the early 20th century included a wealth of new plays written both in Ireland, and by Irish ex-patriots elsewhere. W.B. Yeats, Lady Augusta Gregory, and J.M. Synge were creating a new national theater of Ireland at the Abbey Theatre. They often drew their stories from the fabric of Irish life. Oscar Wilde and George Bernard Shaw were meanwhile writing important (and often hilarious) works on the world stage.

Today we're going to walk through a couple of statistical approaches to answer the question: "is coffee from the local cafe, Caf-fiend, better than that other cafe, The Blend Den?" We'll build a two sample t-test which will tell us how many standard errors away from the mean our observed difference is in our tasting experiment, and then we'll introduce a matched pair t-tests which allow us to remove variation in the experiment. All of these approaches rely on the test statistic framework we introduced last episode.

Hank tells us the background story and explains the importance of the science of classifying living things, also known as taxonomy.

In which John Green teaches you about the American Revolution and the American Revolutionary War, which it turns out were two different things. John goes over the issues and events that precipitated rebellion in Britain's American colonies, and he also explores the ideas that laid the groundwork for the new American democracy. Find out how the tax bill from the Seven Years War fomented an uprising, how the Enlightenment influenced the Founding Fathers, and who were the winners and losers in this conflict.(hint: many of the people living in the Colonies ended up losers) The Revolution purportedly brought freedom and equality to the Thirteen Colonies, but they weren't equally distributed. Also, you'll learn about America's love affair with commemorative ceramics and what happens when rich white guys take the reins from reins white guys, and put together a society of, by, and for rich white guys.

Test statistics allow us to quantify how close things are to our expectations or theories. Instead of going on our gut feelings, they allow us to add a little mathematical rigor when asking the question: “Is this random… or real?” Today, we’ll introduce some examples using both t-tests and z-tests and explain how critical values and p-values are different ways of telling us the same information. We’ll get to some other test statistics like F tests and chi-square in a future episode.

And thus begins the most revolutionary biology course in history. Come and learn about covalent, ionic, and hydrogen bonds. What about electron orbitals, the octet rule, and what does it all have to do with a mad man named Gilbert Lewis? It's all contained within.

Today we’ll explore how sociology defines family and the different terms used to describe specific types of family. We’ll look at marriage in different societies, as well as marital residential patterns and patterns of descent. And, of course, we’ll go over the three sociological schools of thought on the societal role of marriage and family.

Why is gender even a thing? To answer that, we’re going back to our three sociological paradigms and how each school of thought approaches gender theory. We’ll look at the structural functionalist view that gender is a way of organizing society into complementary roles, the symbolic interactionist take on how gender guides our daily life, and conflict theory’s ideas about how gender distributes power within society.

Today we’ll discuss two theories of global stratification. First, we’ll go over modernization theory and Walt Rostow’s Four Stages of Modernization. Next, we’ll explain dependency theory, the legacy of colonialism, and Immanuel Wallerstein’s Capitalist World Economy Model.

Last week we introduced deviance as a concept, but today we’re going return to our major paradigms in sociology and how each approaches deviance. We’ll explore how structural functionalism sees deviance fulfilling a function in society; how deviance is constructed, according to symbolic interactionism; and finally, how conflict theory views deviance as tied to power and inequality.

It's time to heat things up! LITERALLY! It's time for Hank to talk about the history of Thermodynamics!!! It's messy and there are a lot of people who came up with some ideas that worked and other that didn't and then some ideas that should have come first actually were figured out second.

This week on Crash Course Theater, Mike is acting like theater started in Greece. Well, for the western theater, this is true. The earliest recorded drama in the west arose in Athen, and these early plays grew out or religious ritual. Namely, they evolved from the worship of Dionysus, god of wine, fertility, and RITUAL MADNESS. That's right. I said RITUAL MADNESS

This week we’re exploring aerospace engineering and its two main fields: aeronautical engineering and astronautical engineering. We’ll explore life & buoyancy, propulsion systems, and the challenges of managing the human body in space.

In which Stan Muller teaches you about our third branch of Intellectual Property, trademarks. A lot of people confuse trademark and copyright. Trademarks apply to things like company and product names and logos, packaging designs, and commercial designs. Basically, copyright protects ideas, but trademarks protect the things that help consumers tell companies apart. This ensures that consumers know the source of the goods they're buying. Without trademarks, it would be really difficult to buy the same product twice, and very easy for unscrupulous companies to pass off fakes and knock offs of the products you want. I'm telling you, you like trademarks.
