Thanks for all your replies. I know it doesn't matter how the setup is constructed. But in order to really understand what's going on, at least in my head, I need to understand where is that crucial point, that difference that causes a particle to behave one way and then suddenly and...
Okay, now I am starting to understand the difference. So its not that there is something inherently different in the detector vs the screen. Its that the detectors are simply set up in a way that will give info on which path the photon took, whereas a screen can not obtain this info.
So how...
If I understand correctly, the difference between when the detector is "looking at" the photon vs when the screen is in place is that it changes whether/what we know about which slit the photon traverses to. If we know which slit, particle behavior results, if we do not, wave results. As you put...
Okay, so the time of detection is what matters from what you are saying. So from the experiment, both the detector and the screen should "come into contact" with the photon AFTER the photon has traveled through slit(s). However, as long as it is AFTER the slits, there should not be any...
Thanks for the reply! In this experiment described by the Putting Time in a (Leaky) Bottle article, the detectors are actually placed BEHIND the screen. The screen is able to open and close like "venetian blinds". After the photon has already gone through the double slits, if the screen remains...
How does a screen make a particle behave differently than a "detector"?
I was reading a 2007 Newsweek article Putting Time in a (Leaky) Bottle. In one version of the double slit experiment, if you fire photons through double slits and have a screen on the other side, your results are a wave...
