Re: The Strangest Numbers in String Theory - Greg Egan

"Re: The Strangest Numbers in String Theory

The article was intriguing, but John Huerta’s thesis with all the details looked a bit scary, or at least the kind of thing I’d need to spend six months on to really understand.

Here’s a naive question. The article seemed to imply that you might be able to construct an interaction Lagrangian between fermions and bosons in Riemannian 4-dimensional space by treating both as quaternions, and just multiplying them in the quaternionic way. But don’t you need a scalar for the Lagrangian?"
