Hello
\n\nI wanted to get a taste of this, just to know if I could understand the ideas in the challenge, but while I get the general principle, I feel stuck by the maths involved.\nIn my course at University, we never went there, while we talked about the physics concepts.
\n\nBut I guess that all this stuff would be useful to make some progress.\nSo please, does anyone know some good ressources about the kind of maths involved (Lagrangian, Hamiltonian and so on...)?
\n\nWikipedia is definitely not of any help here, as it was probably written by a mathematician for other math-headed people, and if you don't take the concepts in order/lack this kind of culture, it is not possible to get the thing.
\n\nThanks
