Case 1: Pass electron beam through double slit, after which beam strikes passive detection screen. Results on screen shows a wave-like pattern of troughs and valleys of intensity as if the electrons are interfering with each other like two sets of ocean waves.
Case 2 (close one slit): Pass electron beam through single slit, after which beam strikes passive detection screen. Pattern on screen does not show a wave-like pattern (instead, particle-like).
And interestingly, in the double-slit case, even if you slow down the electron beam so that each electron goes one at a time, the pattern that emerges on the detection screen still shows the wave-like pattern, as if the electrons as a group are interfering with each other like the two sets of ocean waves.
Basically what you mentioned does not have anything to do with the act of “observation” affecting the choice of what the electron wants to do, right? No hocus-pocus “electron intelligence”...
Just that the electrons produce interference patterns through a double slit, whether they are fired en-masse or one by one, and they produce a single pattern, when fired through a single slit.
Did I infer the above correctly?
