Hi Marsha

"this calculation for spin is not just 
mathematics; it is real."  What conclusion am I to leap to from that statement? 

well the spin is not derived from a mathematikal model, it is just there, like the rotation of the earth.
But it fits into a mathematikal model, and is predictable.

partikels have their own laws, they do not follow the normal laws.
