                Srinivasa Ramanujan's approximation for the natural logarithm of n! is better than Stirling's.
homework assignment: Show that the variance of the binomial distribution is pqN.  Show that the solution of the diffusion equation satisfies that equation.  Take the Poisson limit of the gaussian distribution.  Use Ramanujan's formula to cast the binomial distribution into a form without factorials.
                Solutions to the first set of homework problems.

                Second homework assignment: do all these problems.
                Solutions to the second set of homework problems.
                Ott's introduction to chaos.
                Handwritten notes on integrable systems.  Ott's discussion of hamiltonian systems.
