Hi. I know I haven’t updated this blog in a while, but I thought I’d let you know about my other blog: http://mathprelims.wordpress.com. I occassionally post on http://cjohnson.tumblr.com too, but that kind of goes in spells.
In any event, you can always check out http://www.friendfeed.com/cjohnson for all of my updates.

According to an article on Physorg.com, scientists from MIT and NIST have determined that Einstein’s famous equation is “… correct to an incredible accuracy of better than one part in a million.”
43rd Mersenne Prime Probably Found
The 43rd Mersenne prime (a prime number one less than a power of two; all ones in binary) has probably been found. From the MathWorld news article:
Less than a year after the 42nd Mersenne prime was reported (MathWorld headline news: February 18, 2005), Great Internet Mersenne Prime Search (GIMPS) project organizer George Woltman is reporting in a Dec. 18 email to the GIMPS mailing list that a new Mersenne number has been flagged as prime and reported to the project’s server. If verified, this would be the 43rd known Mersenne prime. A verification run on the number has been started, and will take a week or two to complete.
The Slashdot post also mentions the EFF Cooperative Computing Awards which has a one-hundred-thousand dollar reward for the first person to find a prime number with at least ten-million digits in base ten. This number isn’t that long, but it may mean that the next big prime found will land someone some nice cash.
