Just tell them "weeeeeeeee"

Ah him as well?!? It's just impossible to judge someone's character. His lectures on yt are incredible

He's coming in like a wrecking ball.

I think I recognize him as a professor that takes teaching… I’d say seriously… but like, im not quite sure that’s entirely accurate.

Let’s say “passionate” and “memorable”, and perhaps even “vigorous”

I think a lot of them still rely on intuition and human level thoughts experiment. See The Feynman Lectures on Physics for a physicist using intuition. For example, when he explains the Fermat Principe with the lifeguard problem: the path of least time running on the beach and swimming to the victim is not the least distance. If you consider that you run faster than you swim, then you should run a bit further so you swim a bit less. This is analogous to the bending of a light ray (refraction, "broken" stick) when it enters water.

Einstein is also famous for those: https://en.wikipedia.org/wiki/Einstein's_thought_experiments

Visualizing for me breaks down as soon as we get smaller than grains of sand. And even grains of sand have some really weird and freaky effects that my brain just won't process well.
