| Nov 25, 2017 at 16:23 | comment | added | Photon | There is an interesting talk by Anthony Zee on this topic (exactly the "why" part): theorie.physik.uni-muenchen.de/lsluest/seminars/asc_kolloquium/… Unfortunately the server is very slow, I'd advice you to save the video file on your hard drive and then watch, rather than streaming it. | |
