The central part of the talk will be about a simple financial toy model that demonstrates a symmetry physicists call "local gauge invariance." This type of symmetry is ubiquitous in physics; e.g. it is found in both the standard model and general relativity.
Intriguingly, the dynamics of this toy model is surprisingly determined by a physics equation famous enough to appear on T-shirts...</i></span>
