Money and Debt: Crash Course World History 202
In which John Green teaches about filthy, filthy lucre. Money. And Debt. So, what is money? And what is it for? And why do we use money? And why does it all disappear so quickly after payday? John will look into 75% of these questions, and if he doesn't come up with answers, we'll get into some interesting ideas along the way, at least. This week we'll investigate whether money displaces barter, then leads to war, slavery, and what we think of as civilized social orders. We'll also see what old Adam Smith thinks of big money, no whammies, this week on Crash Course.

Crash Course Public Health Preview!
Welcome to Crash Course Public Health! Over the next 10 episodes, Vanessa Hill unpacks what public health is, who does public health work, and why thinking about it is so important! Public Health is so much more than just washing your hands, adhering to smoking laws, or wearing your seatbelt -- although it is those things too. Broadly, public health is an approach to preventing disease, prolonging life, and promoting health for everyone. So over the course of this series, we'll show you the many ways the story of your health isn’t just about you, and how it’s about so much other stuff like the social, economic, and environmental conditions that impact all of us.

Los Angeles Uprisings: Crash Course Black American History #45
In this episode of Black American History, Clint Smith teaches you about the complicated history of racial tension in South Central Los Angeles. You'll learn about the Watts Rebellion of 1965, a 6-day uprising in response to police brutality that shaped the landscape of racial tension in southern California for years to come. This tension culminated in two major events -- the murder of Latasha Harlins and the beating of Rodney King in 1991 -- which incited the L.A. Uprisings of 1992.

War and Civilization: Crash Course World History 205
In which John Green investigates war, and what exactly it may or may not be good for. Was war a result of human beings organizing into larger and more complex agricultural social orders, or did war maybe create agriculture and "civilization?" It's hard to know for sure, but it's sure fun to think about. Crash Course is on Patreon!

Stress is Bad for Your Health: Crash Course Public Health #5
Our identities, societies, and health are all mixed together in cool, weird, and often deeply unfair ways. One of the big factors that comes out of that mix is stress. Stress impacts our health in a number of ways. In this episode of Crash Course Public Health, we’re going to go beyond the basics and look at the ways society affects our stress, which in turn impacts our health.

What is Public Health? Crash Course Public Health #1
We often think of health as a self-centric phenomenon that begins and ends with "me", but as we'll explore throughout this series our personal health is just one plot line in a rich story of evolving research and policies that make up the world of public health. So what is public health anyway? Well, public health is an approach to preventing disease, prolonging life, and promoting health for literally everyone. It is a money-saving, life-extending, world-bettering cheat code for improving the world, so we'll spend the rest of this series examining how and where it is working, where it isn't working, and how so much of our health is influenced by the world around us.

How Does Public Health Tackle Outbreaks? Crash Course Outbreak Science #10
Public health activities are all the ways society coordinates to deliver better health to people. That may sound super broad, and it is, so in this episode of Crash Course Outbreak Science, we'll take a look at public health works to prevent outbreaks. We'll learn what public health is and what public health agencies do, look at the three tiers of public health responses, and revisit one of our favorite fictional cities to see these responses in action. This episode of Crash Course Outbreak Science was produced by Complexly in partnership with Operation Outbreak and the Sabeti Lab at the Broad Institute of MIT and Harvard—with generous support from the Gordon and Betty Moore Foundation.

Rethinking Civilization - Crash Course World History 201
In which John Green returns to teaching World History! This week, we'll be talking about the idea of civilization, some of the traditional hallmarks of so-called civilization, and why some people would choose to live outside the civilization model. It turns out that not everyone who lives outside of what we traditionally think of as a "civilized" social order is necessarily a barbarian! To defuse any tension you may be feeling, I'll just tell you now that the Mongols are back. You'll learn about Zomia, swidden agriculture, and even a little about anarchy! Crash Course is on Patreon!

Anita Hill and Clarence Thomas: Crash Course Black American History #46
Today, Clint will teach you about the Supreme Court confirmation hearing of Clarence Thomas. During the screening process, Anita Hill came forward alleging that Thomas had sexually harassed her when the two of them worked together at the Department of Education. The public response to Hill's allegations was tense and split the Black American community along gendered lines. Thomas's nomination was ultimately confirmed by a margin of 52-48, and he became the second Black American appointed to the U.S. Supreme Court.
