I think it's less about some people being especially good at math than mathematics education being especially terrible and uninspiring. 3blue1brown's approach to math pedagogy had really changed how I'm able to see math and to understand it's profundity (as someone who didn't get any further than you, it sounds like, in formal math education [I never took calculus in school.]).

This is also a great series of videos about how, like it says on the tin, the imaginary numbers are real:

The second playlist is great, thank you! As someone with near zero math knowledge, it was very exciting learning that imaginary numbers are a beautiful and intuitive concept. Really makes me want to start playing with frequency domain stuff. Also, the reveal of the mapped video visualization... the whole series is worth watching just for that moment.

That's lovely to hear!

If you're interested, here are some videos about Fourier analysis:

I was hoping one of those links was Reducible! :-) His videos on image encoding are fantastic.
