| Apr 29, 2010 at 16:46 | comment | added | Theo Johnson-Freyd | The Dirac belt trick = Feynman plate trick in Andrea's question does demonstrate that SO(3) has a connected double cover --- your quote does this as well. And this cannot happen for simply-connected spaces. | |
| Apr 29, 2010 at 14:02 | comment | added | Andrea Ferretti | I vote not to close, as that question is different (I am the asker). In my case I knew how to compute the fundamental group of SO(3), the problem was more to understand precisely where (in what space) is the loop drawn when the waiter moves the dish. A modelization problem, in some sense. | |
