Rocks are mesmerizing. Anthropological research suggests that even ancient humans went out of their way to transport special rocks over long distances. And who among us hasn’t done the same?

After several series diving deep into the humanities, Crash Course Geology was a chance for us to explore a new STEM subject (alongside Scientific Thinking).

The Earth we know now is very different than it was two billion years ago… and yet, to a rock, it’s the same world. That’s the heart of geology: while Earth is ever-changing, geologic rules and processes remain the same. By uncovering these constants, we can reveal our planet’s past, learn how to th

Sometimes we have a clear idea of a series’ themes before we start scripting, other times they emerge as we write the episodes. For this series a few strong themes emerged early on.

In a swirl of information, it can feel hard to tell which way is up. On the news, in our FYPs, and around our dinner tables, we’re confronted by scientific claims about our health, safety, and future. Even our own brains can form biases that lead us astray! But we can get unstuck, keep our wits abou

Later this month, we’re premiering Crash Course Latin American Literature! It’s a special series that wouldn’t exist without a small but mighty group of people: literary translators.
