;;; The Bolzmann formula for entropy as a measure of molecular disorder.
;;;
;;; Consider a container partitioned into two equal volumes. The number of ways,
;;; P, in which N molecules can be divided into two groups, N1 and N2, is given by
;;; the simple combinatorial formula
;;;
;;;                     P = N! / N1! N2!
;;;
;;; in which N! = N(N-1)(N-2)...3*2*1. The quantity P is called the "number of
;;; complections" (see Landau and Lifschitz, 1968) [p. 10]

General Programming

Here's a self test you can take to see if you have strong programming skills. For each of these questions, feel free to use your programming language of choice. The questions are progressively more challenging:

1. Write a program to generate 100 random integers between 1 and 100. It should generate exactly the same numbers each time you run it. Bonus: If you wonder whether the distribution should be normal or uniform, give yourself extra points.
