Mathematics to explain everything

Garrett Lisi uses math to describe everything

Surfer dude, Garrett Lisi lives in his van on a beach in Maui. Using a type of algebra he calls E8, Garrett has developed an exceptionally simple theory of everything -- a grand unified theory that explains all the elementary particles, as well as gravity. (link to pdf of paper found below)

Lisi describes how gravity, the standard model bosons, and three generations of fermions can be unified as parts of an E8 superconnection. This unified field theory attempts to describe all fundamental interactions that physicists have observed in nature, and stands as a possible theory of everything, unifying Albert Einstein's general relativity with the standard model of particle physics.

"I think the universe is pure geometry - basically, a beautiful shape twisting and dancing over space-time. Since E8 is perhaps the most beautiful structure in mathematics, it is very satisfying that nature appears to have chosen this geometry."

"This is an 'all or nothing' kind of theory -- meaning it's going to end up agreeing with and predicting damn near everything, or it's wrong. At this stage of development, it could go either way." Garrett Lisi

This video explains how mathematics predicts reality

Warning, even though I have a degree in physics education, the material presented was way over my head. I will watch it again though, because it does give me a glimpse of how mathematics can lead to understanding, perhaps even someday making possible something like electrogravity.

We also mentioned Lisi on Science Buzz last year. Good stuff!

Thanks for the link, Gene. I remembered your post, but was not finding it. The Large Hadron Collider project might find some new particles that Lisi is predicting.

who created math and numbers? where do these things even come from???

Sounds like a good topic for a research project. Numbers were first used about 30,000 B.C. (click on this to learn more).

mathematics can't explain every thing .

That sounds kind of freaky
what if everything could be scientificly explained?
would there be any reason to live if we couldn't find, if we couldn't explore?
think about it.
