Spin has always been confusing. Even the first people to develop the idea of spin thought it had to be wrong. In 1925, two young Dutch physicists, Samuel Goudsmit and George Uhlenbeck, were puzzling over the latest work from the famous (and famously acerbic) physicist Wolfgang Pauli. Pauli, in an attempt to … See more But all of these fabulous discoveries, applications, and explanations still leave Goudsmit and Uhlenbeck’s question on the table: what is spin?
