Nice follow up to your previous post - where Feynman explained the principle. Seeing is ~~believing~~ understanding.

Does anyone know how the wheels are fixed to the axle? One of my neighbours uses a train car wheel as the bottom mushroom anchor for a mooring. He might know (metal shop teacher at our high school) but I'd rather ask the group - then surprise him.

Here you go What they don't explain is the wheel is quite a it warmer than the axle

Richard Feynman reveals what makes a man a great intellectual, and someone he can easily talk to and see as an equal. Has nothing to do with his specific field of study; Feynman even speaks well of a modern artist.

According to Feynman, it's all about pushing your field of study as hard as you can, as far as you can go, such that you are "up against mysteries, all the way around the edge". 2:22 video:

He was absolutely correct I have no more in common with an advanced nuclear physicist than I do with a brain surgeon or a lawyer and a politician but we can all sit and carry on a quality conversation, well maybe not so much with lawyers and politicos since so many of them have very limited intellect thus have closed off their minds.
