About the Guest:
Garrett Lisi is an American theoretical physicist known for "An Exceptionally Simple Theory of Everything." It proposes a unified field theory combining a grand unification theory of particle physics with Albert Einstein's general relativistic description of gravitation, using the largest simple exceptional Lie algebra, E8. He works as an independent researcher without an academic position, enjoying the outdoors and surf of Hawaii.
