An elegant recursive method for getting large integers that are certifiably prime outperforms traditional ways of generating mere "probable primes".

We present a number of programs to investigate and visualize chaos as it occurs with iterated application of functions. We look at ways to picture orbits under repeated ...

Here are solutions to the two problems I listed at the end of my tutorial article on importing and exporting data in Volume 2, issue 3 or the Journal. I strongly encourage ...
