    This was one of the points of contention with the quantum revolution of the beginning of the 1900’s, schrödinger came up with the equation, which fitted like a glove for a lot of scenarios, but it had an imaginary component, which baffled a lot of people since it could imply reality uses such numbers at a fundamental level

        That’s actually a good point I had never considered! In a way you could consider that “negative numbers are imaginary as well”

          And that’s never something I considered. You can’t see a negative amount of apples. Must be imaginary!

      What’s really screwy is you can force light to only travel as a evanescent wave. It’s completely undetectable without a second interaction, but light must transmit energy using the purely imaginary part of the complex wave.

      The imaginary component definitely has some physical meaning, it’s not just a useful mathematical trick.
