A great video, and I noticed the actual linked article here suspiciously follows the exact same structure and examples that Feynman does in his explanation. It would have been nice to acknowledge the fact that the author was probably watching Feynman explain it while writing. But it seems to be a student fun journal, and has made a few hundred people think, so why get upset?
Maybe both Feynman and the author copied the explanation from a third source.
Love to hear Richard Feynman explain anything.
Right? I wish he was alive today so he could do a ton of YouTube videos explaining simple counterintuitive concepts like this.
