## Classical Mechanics

Classical Mechanics (Fall 2007, Stanford Univ.). Instructor: Professor Leonard Susskind. Our exploration of the theoretical underpinnings of modern physics begins with classical mechanics, the mathematical physics worked out by Isaac Newton (1642-1727) and later by Joseph Lagrange (1736-1813) and William Rowan Hamilton (1805-1865). We will start with a discussion of the allowable laws of physics and then delve into Newtonian mechanics. We then study three formulations of classical mechanics respectively by Lagrange, Hamiltonian and Poisson. Throughout the lectures we will focus on the relation between symmetries and conservation laws. (from theoreticalminimum.com)
