I just wanted to add something regarding ”collapsing the wave function” of the electron, making it act like a particle. This short film acts as though it is a great mystery. Imagine you are blind or in a dark room. There is a guitar string vibrating. You cannot see it, but you want to know exactly where it is. Since it is vibrating, it’s postition is like a wave function. You cannot see it, so how do you observe where it is exactly at a given time? You reach out and put your finger on it, then let go as quick as you can. Now you know where it is, for sure. But wait, it isn’t vibr ...

I think this movie tries to way over-simplify the particle/wave duality of electrons. The reason that ”observing” collapses the wave function and ”causes” the electron to act like a particle is that, in order to observe an electron, you need a method to do so. For example, a common way to observe things is to look at them. In doing this, we are really just observing the light reflected. So, scientists use photons, another quantum ”wavicle”. The photon interferes with the electron before the electrons even hit the wall, changing the results of the experiment. It is difficult to real ...
