Thu, 20 Sep 2007 16:00:00 -0500 - The Wolfram 2,3 Turing Machine Research Prize
A universal Turing machine is powerful enough to emulate any standard computer. The question is: how simple can the rules for a universal Turing machine be? Since the 1960s it has been known that there is a universal 7,4 machine. In A New Kind of Science, Stephen Wolfram found a universal 2,5 machine, and suggested that the particular 2,3 machine that is the subject of this prize might be universal. The prize is for determining whether or not the 2,3 machine is in fact universal.
Tue, 29 May 2007 15:30:00 -0500 - The Math(ematica) behind Television's Crime Drama NUMB3RS
Viewers of prime time television will likely be quite familiar with police chases, blood-stained bodies, and massive explosions. What they may be less familiar with is a protagonist whose job title is "math professor" and who uses crime investigation techniques that delve deep into mathematical concepts and equations. Nevertheless, that's exactly what viewers are likely to find on the CBS Paramount television crime drama NUMB3RS, which airs at 10 p.m. U.S. Eastern on Fridays. Even before the show first premiered in January 2005, a group of researchers at Wolfram Research has been part of the core group of advisers who assist with all aspects of the the mathematics in the show. NUMB3RS remains one of the most popular programs on television, and its co-creators Nick Falacci and Cheryl Heuton have been the recipients of a number of prestigious awards for science communication to a general audience. Most recently, Nick and Cheryl were honored with a Public Service Award from the National Science Board, presented at the U.S. State Department diplomatic reception rooms in Washington, DC on May 14. We at Wolfram Research count ourselves fortunate to be primary consultants for NUMB3RS, and more fortunate still to have been invited by Cheryl to attend and take part in the award presentation.

Thu, 23 Mar 2006 12:00:00 -0500 - 43rd Mersenne Prime Found
Less than a year after the 42nd known Mersenne prime was reported (MathWorld headline news, February 26, 2005), the GIMPS project has discovered the 43rd known Mersenne prime: 2^30402457 - 1. The discovery was made by Drs. Curtis Cooper and Steven Boone, professors at Central Missouri State University on December 15, tentatively announced by GIMPS organizer George Woltman on December 19, and independently verified by Tony Reix on December 25. The new Mersenne prime has 9,152,052 decimal digits, making it not only the largest Mersenne prime known, but also the largest known prime of any type.
Sun, 25 Dec 2005 08:00:00 -0500 - 43rd Mersenne Prime (Probably) Found
Less than a year after the 42nd known Mersenne prime was reported (MathWorld headline news, February 26, 2005), GIMPS project organizer George Woltman is reporting in an email message that a new Mersenne prime has been reported to the GIMPS server. A verification run on the number has been started, and will take a week or two to complete. The potential prime was identified by an experienced GIMPS participant and no errors were reported during the run, so it seems likely that a new Mersenne prime has indeed been found. While the exponent of the potential prime has not yet been revealed, it has has fewer than ten million digits.
Mon, 19 Dec 2005 17:00:00 -0500 - RSA-640 Factored
A team at the German Federal Agency for Information Technology Security (BSI) recently announced the factorization of the 193-digit number known as RSA-640. The team responsible for this factorization is the same one that previously factored the 174-digit number known as RSA-576 and the 200-digit number known as RSA-200. While RSA-640 has slightly fewer digits than the previously factored RSA-200, its factorization carries the additional benefit of a cash reward of $20,000 awarded by RSA Laboratories as part of RSA's program to encourage research into computational number theory and the practical difficulty of factoring large integers.

Wed, 06 Jul 2005 17:30:00 -0500 - RSA-200 Factored
A team at the German Federal Agency for Information Technology Security (BIS) has announced the factorization of the 200-digit number known as RSA-200. The team responsible for this factorization is the same one that previously factored the 174-digit number known as RSA-576 (MathWorld headline news, December 5, 2003). While RSA-200 is a much smaller number than the 7,816,230-digit monster Mersenne prime known as M42 (the largest prime number known), its factorization is significant because the RSA-numbers serve as benchmarks for users of the RSA public-key cryptography algorithm in choosing suitable key lengths that provide an appropriate level of security for data encryption.
