47th (and Second-Largest) Known Mersenne Prime Announced

Posted: June 11th, 2009, 1:03am MDT

LBL_TAG_TAGS: [LBL_TAG_EDIT]

A new Mersenne prime was reported to the GIMPS server in April, but not noticed until now due to a configuration issue on the server. The discovery has now been verified and officially announced as M42643801, which has 12837064 decimal digits, making it the 46th known Mersenne prime ranked by size, and hence only the second largest. The prime was discovered by Norwegian GIMPS participant Odd Magnar Strindmo.
47th Known Mersenne Prime Apparently Discovered

A new Mersenne prime was reported to the GIMPS server in April, but not noticed until now due to a configuration issue on the server. GIMPS organizer Woltman has verified that the last save file is valid, so the reported discovery appears to be real. Verification and announcement of the value will follow shortly.
The Math(ematica) behind Television's Crime Drama NUMB3RS

LBL_TAG_TAGS: numbers math machine turing prize [LBL_TAG_EDIT]

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.

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.
Mathematica 6 and Wolfram Demonstrations Project Launched

As many of you have probably noticed on the pages of MathWorld, a number of exciting new things have happened in the last few days that may be of special interest to you. The first is the long-awaited release of Mathematica 6. For MathWorld readers who may not need to harness the full computational power of Mathematica themselves but may still be interested in the computations and visualizations it can produce, the new Wolfram Demonstrations Project (http://demonstrations.wolfram.com), unveiled in conjunction with the release of Mathematica 6, contains more than a thousand interactive Demonstrations built with Mathematica.
Record Twin Prime Discovered

The largest known twin prime pair found to date was discovered today through the Twin Internet Prime Search and PrimeGrid distributed computation projects. The new twins are 2003,663,613 2^195000 +/- 1, each of which has 58711 decimal digits.
44th Mersenne Prime Found

LBL_TAG_TAGS: math [LBL_TAG_EDIT]

Less than a year after the 43rd known Mersenne prime was reported (MathWorldheadline news, December 25, 2005), the GIMPS project has discovered the 44th known Mersenne prime: 2^32582657 - 1. The discovery was made by Dr. Curtis Cooper and Dr. Steven Boone on September 4, tentatively announced by GIMPS organizer George Woltman on September 4, and independently verified by Tony Reix on September 11. The new Mersenne prime has 9808358 decimal digits, making it not only the largest Mersenne prime known, but also the largest known prime of any type.

The Norwegian Academy of Science and Letters has awarded the 2006 Abel Prize to Lennart Carleson of Royal Institute of Technology, Sweden. Carleson received the Abel Prize for his contributions to harmonic analysis and the theory of smooth dynamical systems. King Harald of Norway will present the Abel Prize to Lennart Carleson at an award ceremony in Oslo on May 23.
RSA-640 Factored

LBL_TAG_TAGS: rsa encryption math [LBL_TAG_EDIT]

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.
Seven Mathematical Tidbits

While the last several months have not been filled with any particularly earth-shattering new mathematical results, a number of interesting events, findings, and mathematical books have recently appeared. Here is a recap of some of them, including a birthday, some very odd numbers, a whole lot of nothing, two new books, and major milestones for two mathematical websites.
Mathematica's Google Aptitude

Google makes use of unusual mathematically oriented recruiting techniques. These techniques have received additional coverage in the last few weeks and months following the erection of a mathematical billboard in Silicon Valley in July. Google followed their unusual billboard with a math-intensive Google Labs Aptitude Test. Mathematica clearly shows its extremely high mathematical aptitude by easily solving most of these questions, especially when guided by a little research on MathWorld.

You can now sport an elegant, mathematical look by donning a T-shirt bearing the MathWorld logo. The new MathWorld shirt is a short-sleeve white T-shirt made of 100% cotton adorned with attractive mathematical graphics. The T-shirts come in medium, large, X-large, and youth medium sizes, and are available for purchase from the Wolfram Worldwide Web Store (http://store.wolfram.com/view/misc/). In other news, Ed Pegg, Jr. has recently joined the MathWorld team, and a new RSS newsfeed is now in place for more convenient reading of MathWorld Headline News.
