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 does a system try to minimize potential energy?
@VladimirVargas: the probability-energy relationship is the Boltzmann distribution. I'm not sure what more to say - maybe you could post a question and be specific about what you would like to know.

Have you done any research on this? For example have you looked at the Wikipedia article on the linear canonical transformation.
