something you might not know about quantum mechanics: it’s not hard because it’s complicated. in the grand scheme of physics, the math of it is quite well understood. it’s hard because it’s weird. turbulence is complicated. misplace the last digit of a very long number and your whole simulation comes out different eventually. but it’s intuitive. it makes a kind of natural sense. quantum mechanics is cheap to compute, and with all the randomness most errors you could make were on the table already. but it is so fucking bizarre. it’s the kind of thing that seeing isn’t enough to believe. it presents a world where something can be thrown off course by its other self that could have been but wasn’t. a world where things can exist in hindsight without ever having existed in the present. a world where you shine a light through two slits and spend 200 years arguing about what the fuck happened and how many universes it involved. it’s just weird, okay?
