Everywhere I read about the angular momentum / spin of electrons and how a 1/2 spin particle has a unique characteristic that you need to turn it 720 degrees in order to get it turned back to where it was before you started turning it.
How exactly do people "turn" an electron in this fashion? I can't find anything anywhere that explains 'how' we are able to change the direction of the spin like that.
Thanks
