At Carbondale library

I am in Carbondale library here to spend some time working on my thesis. Just done with some bill payment here on computer. Yesterday was productive I got done several things. I need some time to peruse over the derivation of Bernoulli's formula. I refreshed my concept of product of sum and sum of product and the generating function derivation of Catalan numbers. Today I should complete the trivial proof of uniqueness of bipartition for a connected bipartite graph and write a function in maple that models the gambler's ruin problem.
