It turns out that some sides of magnets will not stick together. We have forgotten this fact and rediscovered it multiple times in the last thirty minutes, and this scientific discovery is not at all appreciated.
Admittedly, I had a similar reaction to Biot-Savert’s law back in E&M. I did manage to not throw things at the time.
I guess too young for Feynman’s sitdown discussion on why magnets are how they are, but maybe in a few years you can blow their mind with the idea that magnets repelling each other is very much related to why things feel solid to us. Or Sagan’s bit about how atoms (and thus matter itself ) are mostly nothing at all.
