Speedy Caterpillars

Last spring I wrote about a YouTube channel called Smarter Every Day. It continues to be one of the best web video series that I’ve found. The last episode about caterpillars was pretty incredible. Imagine you’re a caterpillar and you want to move as quickly as possible. There’s only so fast that you can walk by yourself, but what if 100 of your friends are walking to the same spot? How could you walk faster as a group than as an individual?

Watch the episode to find out:

And while you’re at it, I also recommend the Minute Physics channel. In each video he very quickly breaks down a complicated physics topic.
