### The Peculiar Math That Could Underlie the Laws of Nature

There’s a suspicion that fundamental particles and forces spring from strange eight-part numbers called “octonions.

Algebra, string theory and physics. If you love math, you will love this article about Cohl Furey, a physicist from Cambridge University.

Cohl Furey, a mathematical physicist at the University of Cambridge, is finding links between the Standard Model of particle physics and the octonions, numbers whose multiplication rules are encoded in a triangular diagram called the Fano plane. Susannah Ireland for Quanta Magazine

There’s a suspicion that fundamental particles and forces spring from strange eight-part numbers called “octonions".

.......all multiplicative chains of elements of $latex \mathbb{R}\otimes\mathbb{C}\otimes\mathbb{H}\otimes\mathbb{O}$ can be generated by 10 matrices called “generators.” Nine of the generators act like spatial dimensions, and the 10th, which has the opposite sign, behaves like time. String theory also predicts 10 space-time dimensions — and the octonions are involved there as well. Whether or how Furey’s work connects to string theory remains to be puzzled out.
