Making your work available to the mathematical world is essential for every mathematician, young or old.
One way is to use the arXiv, a free online preprint archive. In this article, we give a brief description of the arXiv.

The fortieth known Mersenne prime was discovered in November last year, and was verified in December. In compact form, the prime is 2^20996011 - 1, and has over 6 million digits. It was discovered as part of a group project known as GIMPS, and the group has discovered the last 6 Mersenne primes to be found since 1996.

If you ever need to copy pages
from an old book, you should know about
drop-edge copiers.

Its often seems that mathematics doesn't get much play in any media outside of the mathematics community (that is other than the "Fermat's Last Theorem Proved!" variety).
That's why this story (same title as this post) at kuro5hin.org caught my eye. Read, revel and enjoy!

Just in case you missed the NY-Times article (or the recent slashdot story, or the mathworld story, or otherwise heard the news) recent work from the Russian mathematician Dr. Grigori Perelman may prove (among other things) the famous Poincaré Conjecture!

[Editor's note: although it is our practice not to run job
advertisements in the *Concerns*, this is perhaps the most unusual
job advertisement we have ever been asked to run.]
Researchers at the National Institutes of Health (NIH), National Institute of Neurological Disorders and Stroke (NINDS), are conducting
research studies of the cognitive processes underlying the solving of algebraic math problems. You will be asked to mentally solve a variety of integral calculus problems and then complete a follow-up questionnaire.
The full announcement is posted at

Erik D. Demaine, Susan Hohenberger, and David Liben-Nowell of the Massachusetts Institute of Technology's Laboratory for Computer Science have analyzed Tetris from a computational perspective, focusing on the computer resources required to play the game successfully.
Tetris, along with other games such as Minesweeper, falls into the NP-complete category.
