Writes Brent Peterson:

The video of “Feynman and the Train” is the second I’ve seen in two days explaining how to overcome the mechanical problem of turning a wheeled vehicle. The first is below, from when GM was still viable. I’m guessing the 1930s. This sort of thing is so absent in modern education; even modern engineering education is often so math based as to create a disconnect from actual hands-on engineering. I had to learn it on my own. There are a lot of interesting parallels between math-based engineering education and the Keynesian school.
