The Hydrologic and Carbon Cycles: Always Recycle! – Crash Course Ecology #8

Adorable story alert! So I was hanging out with my 2-year-old second cousin in the ocean in Florida and we’re jumping up and down with the waves and it’s fun but then the water got all calm and I said, “Oh, no more waves!,” because, like, that’s the top tier of communication I’m going for… Read More »

Ecosystem Ecology: Links in the Chain – Crash Course Ecology #7

There’s a lot of ideas that we just assume that we know a lot about because we hear about them all the time. For instance, I know what pop music is, but if you were to corner me at a party and say, “Hank, what is pop music?”, I’d be like, “It’s, uh…it’s like, uh…the… Read More »

But he knew that not everyone had been exposed to the Bible, or… Read More »

What Is Justice?: Crash Course Philosophy #40

Justice is one of those things that people talk about all the time, without really being specific about what they mean. Activists talk about economic justice. Police and lawyers talk about criminal justice. Parents, teachers, and students talk about justice a lot, too, though they may never use that word. When there’s a fight on… Read More »

The Crusades – Pilgrimage or Holy War?: Crash Course World History #15

Hi there! My name is John Green; this is Crash Course World History, and today we’re going to talk about the Crusades. Ohhh, Stan, do we have to talk about the Crusades? I hate them… Here’s the thing about the Crusades, which were a series of military expeditions from parts of Europe to the Eastern… Read More »

Catholic Counter-Reformation: Crash Course European History #9

Hi I’m John Green and this is Crash Course European History. So, last week we took a break from religion to show that amidst warfare and bitter controversy over doctrine, people were inventing and innovating and enslaving. Europeans were eating new foods, hanging out more in cities, and making advances in commerce and legal protections… Read More »
