In physics, Lagrangian mechanics is a formulation of classical mechanics founded on the stationary-action principle (also known as the principle of least action). It was introduced by the Italian-French mathematician and astronomer Joseph-Louis Lagrange in his 1788 work, Mécanique analytique.

Tīmeklis2024. gada 22. maijs · 13.3: Derivation of the Lagrangian. The purpose of this chapter is to find the voltage V(r) and the charge density ρch(r) around an atom, and we will use calculus of variations to accomplish this task. We need to make some rather severe assumptions to make this problem manageable.
