Semi retired old time computer nerd who started programming on a Commodore Pet.

Since I'm also active in the Physics forum I should add that I started as a theoretical chemist, moved into solid state photochemistry and finally worked in industry as a colloid scientist. I only became a full time computer nerd in 1997.

comment Why is $|\Psi|^2$ the probability density?
See this paper by Scott Aaronson. He considers other ways of calculating the probability density and shows that the 2-norm is the only physically reasonable one.
