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 What is the relationship between the Young's modulus of a material and the elasticity of a free fall collision
I'm voting to close this question as off-topic because it is too ill defined. A collision between bodies with infinite Young;s modulus would be singular with an infinite force during the collision. The question could be rephrased as what is the relationship between the Young's modulus and the elasticity of collisions or something like that.

See Ayushya's answer. There's lots of physics here and the question shouldn't be closed.

comment Alternative formulations of Lagrangians and Hamiltonian?
That the universe obeys the principle of least action is one of its defining characteristics. I don't know of any more fundamental statement of the principle - that's just the way the universe is. I believe there have been attempts to show the principle could be emergent from some deeper structure (cellular automata?) but I don't recal the details.
