Just a question. I'm just getting back into re-learning my physics, and learning physics I never had a chance to study.The old Hydrogen Atom stuff we start with is just not enough to deal with anything more complicated - but, deep down, we want it to.
But.....Do you know?....... If two atoms - with velocities - collide and recoil, how much energy is lost from their velocities/momentum?
Is there a formula?................Does it have ugly partial derivatives? (I've completely forgotten how to do them - they look like ugly squiggles to me)
