Elenka is a name of a young bouncing girl who likes and is good at dancing.
I am now reading a book about the history of quantum mechanics written by Manjit Kumar.
It is so interesting to me!
At a chapter, the discovery of the spin of an electron is introduced.
But why is the spin of an electron plus or minus (1/2)h?
I myself tryed the calculation.
Please examine my calculation by yourself.
