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 The spring of air: Why does a piston undergo SHM when it is displaced lengthening the air-column inside a cylinder filled with air?
@user36790: if you pull on the end of a spring and stretch it, the work you do goes into increasing the potential energy of the spring. This is just the same.
