    Anyone actually know what measurment devices are used to observe which slit the electron passes through? How do we know that a specific measuring tool isn’t changing the experiment significantly enough to cause issues with outcome and that the behavior change is abnormal?

      My understanding is that they use something like polarizing filters. Both slits have the same filter, they make a diffusion pattern as the waves interfere with each other. Both slits have different filters, there’s no wave interference and you get two lines.

      Calling it an “observer” is maybe the most damaging name in the sciences since some douchebag decided to call the orthoganal number line “imaginary”

      That’s actually the real lesson from the experiment. The detectors impart a small but real energy barrier and change the distribution pattern of the electron

      Basically if you hold up a ruler to something human scale it doesn’t effect the thing your measuring much. But when you are trying to measure a basketball with something the size of a gymnasium you have to really launch that fucking basketball to open a door and the door has a very noticeable affect on the trajectory of the ball.
