Kurzgesagt – Beyond the Nutshell

Dive into the science behind your favorite Kurzgesagt videos.

If you've ever wanted to go deeper into the science in Kurzgesagt videos, this is the course for you.

With each new video, this course will explore the big questions and investigate the scientific principles behind them. To start, you’ll track mutations to figure out how rabies conquers new animals in the wild, then do some light physics to unravel its path to the brain. Then you'll turn to the big questions of astrophysics and cosmology to uncover the life cycle of black holes and the future of the universe.
