Physicist Garrett Lisi @ Ted Talks

Here at Living in Courage, we love Ted Talks where some of the world’s greatest minds meet in Monterey, California once a year to explore new technology and the people who develop and experience great things in the world. I hope you enjoy this video from Ted Talks and explore more of the available videos.

Working from principles of differential geometry, physicist Garrett Lisi is developing a new unified theory that purports to explain all the elementary particles, and gravity, in one elegant model. His theory is based on a mathematical shape called E8. With 248 symmetries, E8 is large, complex and beautiful — and Lisi believes the relationships of its symmetries correspond to known particles and forces, including gravity.
