quantum mechanics- is the world not what we think it is?
Certain real physical microscopic quantities (e.g. the angular momentum of an electron) obey mathematical laws that are completely unusual. We find that there are only 2 possible spin states of an electron and that measuring the spin state in any 3d axis completely destroys information about the spin state components along another axis.
we find that these quantities can be represented as linear combinations of basis vectors in a complex vector space, hilbert space as opposed to matter in a euclidean space.
this is quite shocking. And I know many of u in this forum are very aware of this, however I hope some people appreciate how mysterious this phenomena is and it show how little we know about nature and how complex it is.
edit: of course this phenomena is correllated to the particle -wave duality of these quantities.
