47th (and Second-Largest) Known Mersenne Prime Announced
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.Fri, 12 Jun 2009 00:03:20 -0500
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.Sun, 7 Jun 2009 11:00:00 -0500

45th and 46th Mersenne Primes Discovered
Two years after the 44th known Mersenne prime was reported (MathWorldheadline news, September 11, 2006), the GIMPS project has discovered the 45th and 46th known Mersenne primes: 2^37156667 - 1 and 2^43112609 - 1. The discoveries were made by Edson Smith on August 23, 2008 (for the larger prime) and Hans-Michael Elvenich on September 6, 2008 (for the smaller prime), and announced by GIMPS organizer George Woltman on September 16. The new Mersenne primes have 11,185,272 and 12,978,189 decimal digits, making them not only the largest Mersenne primes known, but also the largest known primes of any type. The first discovered (and largest) of these prime also earns its finders a $100,000 prize from the Electronic Frontier Foundation for the discovery of a prime number with 10 million or more digits.Tue, 16 Sep 2008 13:30:00 -0500
Two New Mersenne Primes Apparently Discovered
A new Mersenne prime was reported to the GIMPS server on August 23, 2008. This prime was confirmed by Septempber 6, though its value has not yet ben revealed pending independent verification using a different program on a different computer architecture. More amazingly still, during the period required for the first verification of the recently reported new prime a second new Mersenne prime was reported and is currently being verified.Sun, 7 Sep 2008 08:30:00 -0500
New Mersenne Prime Apparently Discovered
A new Mersenne prime was reported to the GIMPS server on August 23. GIMPS organizer Woltman has asked the finder to send the last save file, so it should very soon be known with more than 99% certainty if the reported discovery is true.Tue, 26 Aug 2008 11:00:00 -0500
A New Look and New Features for MathWorld
While MathWorld continues to be the most popular and most visited mathematics sites on the internet, and while its mathematical content continues to steadily grow and expand, MathWorld readers will notice more immediate visual changes the next time they visit the site. Design changes and major new pieces of functionality are generally years in the making for large informational websites like MathWorld. The last time the site received a major upgrade to its infrastructure was in July of 2005. On Friday of last week, we introduced a major update of the MathWorld site featuring improved navigation, higher-quality typesetting, and links to interactive demonstrations. I encourage you to visite the updated site and enjoy the beneifts that the new look and associated functionality provide.Tue, 12 Feb 2008 09:35:00 -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

Learn From Your Mistakes
H.L Mencken once said:Mon, 09 Aug 2010 07:08:45 +0000
"For every problem, there is one solution which is simple, neat and wrong."
I'm sure most of us throughout our academic careers can relate to this statement. However, just think of the learning that comes from making mistakes! For me, I probably maximize my learning when I analyze my mistakes. After all, I don't want to make the same mistake twice! See how you can learn from previous mistakes and take advantage of this powerful learning opportunity.
Let's Talk About Math
Sat, 07 Aug 2010 18:25:13 +0000
Hold the Calculators, Let's Talk About Math! I couldn't recommend a better article for math educators to not only read but to reflect on and move towards implementation. The researchers in North Carolina state have my complete vote of confidence with this strategy. When students are learning math concepts, they need opportunities to talk about their thinking. Teachers need to prompt their thinking with questions like:
...
How do you know?
Explain why you did that?
Is there another way you could solve it? How?
