Electron spin

[partha1963]

Mellow, all Physics Forum member, Please help me to have the answer of question, Why electron spin is +-1/2. What is the reason of integral spin of subatomic particle?

Thanks for deleting my post ... so how do you explain spin (or charge) quantization if you don't like topological explanation (exactly like behind quantization of magnetic field in superconductors)?
