The Living Thing / Notebooks : Lagrangian mechanics and variational calculus

Applied variational calculus.

I don’t really do physics these days, but physicists write the best introductions to variational calculus, which I do do.

“What is the quickest path through these mountains?”

Optimal control, Pontryagin’s maximum principle. Variational calculus, minimising functionals. deriving high dimensional functions as solutions of scalra optimisation.
