What difference does the observation make? S1E1
Sheldon: So, if a photon is directed through a plane with two slits in it and either slit is observed, it will not go through both slits. If it's unobserved, it will. However, if it's observed after it's left the plane, but before it hits its target, it will not have gone through both slits
I admit, i dont understand about 99% of the science on the show. So forgive ne if i dont understand what difference where you see the photon makes on how many slits it goes through
