Mathematicians solve century-old puzzle

by bobbyjoe in Technology


It has taken 120 years but the worlds best mathematicians and computer scientists have mapped out a 248-dimension mathematical structure, knows as E8. Solving E8 is seen as a major step in the study of symmetry, a mathematical field important to our understanding of the origins of the universe. (Image: John Stembridge, based on a drawing by Peter McMullen)

The calculation of the structure takes about 60 gigabytes of space on a computer, or enough space to hold about 15,000 songs in MP3 format. It took 18 researchers from the United States and Europe four years to produce the E8 calculation and 77 hours for a U.S. supercomputer called Sage 77 to provide the solution

E8 is the most complex Lie group known, a 453,060 by 453,060 matrix that exists only in abstract mathematics. Because of its large size, solving its structure was not possible until computing power could improve, according to Jeffrey Adams, the project leader and a mathematics professor at the University of Maryland.

“E8 was discovered over a century ago, in 1887, and until now, no one thought the structure could ever be understood,” said Adams in a statement. “This groundbreaking achievement is significant both as an advance in basic knowledge, as well as a major advance in the use of large-scale computing to solve complicated mathematical problems.”

    Man that is a lot of space. I can’t even fathom the mathematics required to figure that out. You have a really cool blog, definitely not what I thought it was going to be about when I saw the title. Then again the fuzzy logic connection didn’t connect in my brain until I saw the site. Very nice. Thanks for dropping by LifeIsRisky.Com earlier. I appreciate it and hope you will drop back in again. Adding you to my weekly web wanderings!

    Tried to find a contact page but I must have overlooked it. Anyway, just wanted to let you know that once a comment has been approved I was expecting the site to pop me back to the post or the homepage. Instead it just went to a page saying the comment had been approved. No link to homepage or anything. Just a suggestion but it would be a good idea to put an auto load for the homepage there if nothing else.
