PhD Surf Bum Proposes New Unified Theory
Here's a link to the story.
Does anyone here know anything about this that they could dumb down to layman's terms? It seems to relate highly to this E8 pattern. another link, about E8. "E8 is the symmetries of a geometric object that is 57-dimensional. E8 itself is 248-dimensional." So if anyone can explain 248 dimensions to me I'd appreciate it. I'm an EE so I have some background in physics, but this stuff seems to be a little beyond me. |

Lee Smolin is not an idiot. If he likes it, and it is predicting things like the masses of the fundamental particles, it is definitely worth looking at.

[/ QUOTE ] It does not predict masses (explicitly, yet). But it has no free parameters (e.g. coupling constants), so it is very constrained, and would be testable if the theory could be developed further. |

Re: PhD Surf Bum Proposes New Unified Theory
So is anything about E8, or how this theory works explainable to the general public?

Re: PhD Surf Bum Proposes New Unified Theory
I have T-shirt that has the Dynkin diagrams for E8 and several other Lie algebras on it, and I'm not ashamed to admit that.
