The Heisenberg uncertainty principle states that it is fundamentally impossible to know precisely both the velocity and position of a particle at the same time. The only quantity that can be known is the probability for an electron to occupy a certain ...

3.7 The Pauli principle
... Only symmetric or antisymmetric wave functions are allowed when exchanging two indices. Within quantum field theory one can show that particles with an integer number as spin have symmetric state functions while particles with a half number of the spin have always antisymmetric state functions. Thus ...
