Course Material:

[G2]: Herbert Goldstein, "Classical Mechanics", Eds. 2.
[G3]: Herbert Goldstein, "Classical Mechanics", Eds. 3. (Click here for a list of corrections).
[LL1]: Landau and Lifshitz, Vol. 1, "Mechanics".

Nota Bene:

1. All references to [LL2] should be considered supplementary reading, as the presentation during the lectures differs substantially.
2. What Goldstein [G3] calls "Hamilton's principle" is usually called the "principle of stationary/least action".
3. What Goldstein [G3] calls "principle of least action" [G3] 8.6, is usually called the "principle of abbreviated action" or "Maupertuis' principle".
4. Note that Poisson brackets in [LL1] have the opposite sign convention.
5. The treatment of Lagrange equations for semi-holonomic & non-holonomic constraints in [G3] 2.4 is inconsistent with Newton's laws, and has been retracted on [G3]'s errata homepage . For more info, see also M.R. Flannery, "The enigma of nonholonomic constraints", Am. J. Phys. 73 (2005) 265 .
