In the book _In the Blink of an Eye_ by Walter Murch (which is generally about film editing), there's a section that speculates that 24 frames per second somehow resonates with some innate constant of how human vision works, which is wild to think about!
I remember exactly when I learned that, and indeed I found it interesting and thought-provoking at the time. And it's still interesting now, but I personally think it's way less likely true than I did back then
