A teacher told me that electron don’t even really ‘spin’ the way we understand spin. But somehow they can have angular momentum. And what exactly is the concept of half spin?
In: Physics
Wolfgang Pauli, defined the modern concept of quantum spin called it “classically non-describable two-valuedness”.
Which tells you that there is really no room for a conventional intuition about spin. It just is one of the numbers that defines a quantum particle, like charge or mass and is equally arbitrary.
