My day was pretty good. I worked, made a mistake, got over my failure, worked some more. Then I went home, became very intoxicated, and learned about some aspects of Quantum Physics and Quantum Computing. I finally understand what virtual photons are and how they work in Quantum Electrodynamics, so that's good. I learned the principle a few years ago, but I think I actually understand what it is and how it works. One of those epiphany moments where you go "ohhhhhhh" for a few minutes now that your confused, laborious framework has come into a clearer perspective.
