PickVidsFeynman: How the train stays on the track FUN TO IMAGINE 7
Why it was recommended
That doesn’t seem to be a charitable reading and in any case it has to do with wheel taper, more like cone than cylinder. More specifically the nature of the solution was getting two parts of the org, track and train, to work together. While that may seem elementary stuff, anyone at a big org can attest to how often it is tremendously difficult to do sometimes. I write this not as an apologist for commuter rail, which I find excessively expensive and inflexible outside of very circumstances, but as an excuse to link to the lovely Feynman description of why train wheels are tapered: [VIDEO]

What it covers
A short clip from the 1983 BBC series Fun to Imagine in which Richard Feynman explains how a train stays on the track. He covers the geometry of tapered wheels that steer the. It is for a general viewer who does not plan to take a prerequisite first.
