Lie group E8

The World's Most Complex Structure!

Abstract 248-dimensional map may unify the laws of nature. After 120 years of puzzling, mathematicians have mapped out the most complex abstract structure ever conceived, a 248-dimensional representation called the Lie group E8, first predicted in 1887 by Norwegian math genius Sophus Lie. A major theoretical triumph, the result may also hold the key to a unified theory of physics.

The full E8 map is a monster, with almost 100 times as much data as the Human Genome Project. It took a team of 18 mathematicians four years to produce the results, which they finally did with the aid of supercomputers.

A “group” is a set of objects, together with an operation, that exhibit certain symmetries—the set of integers and addition, for instance, form a group. (Add two integers, and you get another integer.) Lie groups are fundamental to physics. 

All the particles and forces in the standard model, the dominant schema of modern physics, are represented by Lie groups, and their study has become an essential tool for understanding—and attempting to unify—the laws of nature.

Ten Types of Women You Need to Avoid


10. The woman who is obsessed with getting married:

You know the type. Desperate to be married... She's the woman who had her whole life laid out like clockwork and with a timeline to give her the perfect life, only to find she hasn't met the perfect man and her biological clock is counting down in seconds. You know she's going to suddenly discover as soon as she's married and gotten the two kids that you are a stinker...but now, you're going to have to deal with her the rest of your life. She's so scary that any man in his right mind would run away....so run.

Joke of the Day

A guy goes up to a girl in a bar and says, "You want to play 'Magic'?" She says, "What's that?" He says, "We go to my house and fuck, and then you disappear."

Doomsday Odds Calculated


As you read this, physicists around the world are slamming millions of subatomic particles together at nearly the speed of light, creating conditions that mimic the universe shortly after the Big Bang. Physicists who assessed these experiments repeatedly concluded that the risk of an accident is extremely low. Max Tegmark of MIT and Nick Bostrom of Oxford University in England weren't convinced, so they decided to calculate the odds.
