I'm a graphics programmer, an amateur physicist, and a sci-fi nerd. I teach computers how to make pretty pictures. I'm excited by beautiful, immersive, story-driven games and interactive fiction. I enjoy messing around with esoteric ideas. I like explaining things.

I currently work for NVIDIA DevTech. Previously, I worked for Sucker Punch Productions on the Infamous series of games for PS3 and PS4.

comment How do we know what type of gauge field to add to a theory?
I'm still digesting this (you did it in a bit more generality than I needed :)), but let me see if I've got the general idea. The problem is that because $g$ varies in spacetime, derivative terms in the Lagrangian pick up unwanted derivatives of $\rho(g)$. To cancel them, we must use a field that transforms under the Lorentz group the same way that derivatives of $\rho(g)$ do—that is, as a dual 4-vector whose components are members of (the $\rho$ representation of) the Lie algebra of $G$. Is that about right?

comment How to numerically solve a complex equation?
This is impossible to answer without being more specific. Numerical root-finding (which is what this is) is a huge topic.
