Sure, it's much more useful for more ideal mechanical oscillators like atoms. Not very universal for springs and stuff like Hooke had in mind. — Kenosha Kid
. Take Hooke's law into 3D (with shear) and you get linear elasticity, the backbone of 90% of engineering mechanics from 19th century through the present day. — SophistiCat
Where did you get that from? 90%? No way. Hooks law doesn't apply to most materials. Even with shear it can't be applied to most materials. Maybe for very small forces, or tiny displacements. Mostly though, a linear algebra just isn't applicable. For a metal spring in the physics class it will do. For an atomic nucleus inside an electron cloud, a Hooke approximation will do. — Cartuna
I recall a paper Hawking gave on how multiverses _restore_ the second law, solving the problem of what happens to information about particles destroyed in black holes. Iirc, it's that over an infinite number of universes, the net loss is zero. But don't trust my ability to — Kenosha Kid
The second law is a statistical law, so yes, it doesn't deliver absolutely certain predictions. — SophistiCat
