So glad I don't have to take the Physics GRE again.

I wandered into a now little-used portion of my hard drive and realized that I'm done with the physics GRE and can delete the four example tests! Yeah!

One of my difficult subjects is E&M (probably cause I never took the undergraduate class in it). A new arXiv preprint shows how to write Maxwell's equations using geometric algebra, one of my favorite math tools:

$$\Box F = c \mu_0 J$$

There. Much simpler. Now I can do E&M problems like a champ.

Bring the qualifying exams on!
