Spin is one of the most heard of concepts in modern physics, yet it is often rather obscure. Are you sure you know what it is?
Spin is not a simple concept and it has an interesting development.
Let's find together how we got to imagine the electrons as spinning charged balls and then forgot about it and went on. From the atomic model by Rutherford, to Stern - Gerlach's experiment up to Schroedinger's equation, we'll find out more about this important concept.
