Please note that the content of this book primarily consists of articles
available from Wikipedia or other free sources online. An Exceptionally
Simple Theory of Everything is a preprint proposing a basis for a
unified field theory, which attempts to describe all known fundamental
interactions in physics, and to stand as a possible theory of
everything. The preprint was posted to the physics arXiv by Antony
Garrett Lisi in November 2007, and was not submitted to a peer-reviewed
scientific journal. The title is a pun on the algebra used, the Lie
algebra of the largest "simple," "exceptional" Lie group, E8.
