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 Is the zeroth law of thermodynamics always observed to be valid?
The zeroth law doesn't apply to the universe because the universe isn't in an equilibrium state. If you have a question about energy conservation of the whole universe then that is a different question, though note that it has been asked here before.

comment Particles interacting with distance invariant force
This is pretty much how the strong force works in the low energy limit. The force does not depend on distance because the forces between gluons causes them to form a flux tube.

@VladimirVargas: yes, that's basically it.
