Oct 16 at 9:15 | comment | added | g.kertesz | Let me add this. We are so accustomed to represent physical quantities with real numbers that we do not even think about it. Reals are a great abstraction, but somehow they are too "fine grained" for physics or anything "real world" for that matter. There are no physical measurements where we get the full spectrum of real numbers. This leads to paradoxes like this one or paradoxes about probabilities. | |
