#PhysicsQuestion: in "A Brief History of Time," Hawking describes how matter particles emit force particles, the recoil changing their directory and the impact changing their target's. This makes sense for repulsive forces, but how does that translate to attractive forces?

Question: What is the derivative of the Lagrangian (of what system I don't particularly care right now) with respect to entropy (or to the time derivative of entropy)? Is this even a sensible question? Can we use the Euler-Lagrange equation for entropy?
