See this thesis: http://umu.diva-portal.org/smash/get/diva2:140361/FULLTEXT01... the basis for this awesome physics simulator: http://www.algodoo.com/ Conservation of the hamiltonian with leapfrog integration is also the principle behind Hybrid Monte Carlo methods http://www.mcmchandbook.net/HandbookChapter5.pdf

That thesis looks insteresting, but is also 472 pages. Is there a TL;DR version?
