Cantankerous astrophysicist and editor. Grandfather and dog owner. I could probably drink less coffee. I think about magnetized turbulence and what it means for the universe.

Speaking ill of the dead is rude, and usually pointless. It causes pain to their families and arrives too late for them to improve their behavior. However, when people insist on deifying someone who, when alive, was a terrible person, I’m willing to make an exception.
