Everyone have a safe and enjoyable break!
The AMS Department currently has the following openings
Try this. On a blank sheet of paper, starting with the number 1, create a spiral of numbers outward from the 1. For example, 1, just beneath it 2, to the right of that 3, above 4, above 5, to the left 6, 7, etc. in a nice gridded sprial of numbers. Now go back and circle the prime numbers you have (2, 3, 5, 7, 11, 13, etc.)
You may notice, as Stanislaw Ulam did in 1963, that some of the prime numbers are linked together in diagonal lines -- some with rather lengthy lines.
Admittedly, not much is discovered about the Ulam spiral, because it is not heavily studied by mathematicians. It does, however, show that there is a clear pattern among prime numbers -- a topic that has been studied extensively.

Professor Receives DOE Funding
A CSM-led research team with principal investigator Paul Constantine has been funded by the U.S. Department of Energy's Advanced Scientific Computing Research program to improve he capabilities of data-inensive physical simulations such as climate simulations. Constantine's team will apply the methods they develop to real inverse problems in chemical kinetics and turbulent flame modeling.
