Yesterday I was tidying up my office and I found something cute on my chalkboard:
Do you see it? Amidst the remnants of a discussion with one of my colleagues, it appears that I now have a Feynman diagram of a Thanksgiving turkey:
Actually, I’m not sure if it’s a turkey, but it’s certainly some kind of poultry. The diagram was drawn by another theory grad student, Yuhsin Tsai. The irony is that we were discussing whether this process should be considered to be a penguin diagram. There are also diagrams called seagull diagrams. I guess physicists have a thing for birds in their diagrams. (By the way, this isn’t the first time I’ve found funny-looking diagrams.)
Hopefully in the near future I’ll be able to write up a few posts explaining how Feynman diagrams work. In the meanwhile, happy Thanksgiving everyone!
