    True! Thanks for the clarification, it’s been a while since i played with the maths of quantum physics!

    After you measure a spin as 100% up, the state will be close to that for a while, si the next measurement has higher chance of being up, with this probability slowly decreasing with time.

      I think that assuming the particle has no (extra?) energy it’s state does stay the same. That is of course not possible in real life though but the <20 millikelvin in some quantum computers get pretty close.

      Also I think nobody says they measure it as 0/100% up, They just say up or down in my limited experience.

      Does anyone have any good resources on quantum mechanics? (Most of my information comes from a few professors) There’s some useful stuff on chem libretexts (I think that’s what it’s called) for simple wave functions, but it doesn’t seem perfect.

        I have old college textbooks in my library, Cohen-Tannoudji. I’m not sure about online resources though…
