I'm a pessimist. I always have been, and I probably always will be. When I started saying in early March that the coronavirus would probably be one of the deadlier viruses in history, Facebook friends accused me of promoting hysteria, of rooting for the virus, of wanting to hurt the president. Just for the record, my warnings were motivated by none of those. I was motivated because I had done the math. But the concept of exponentiation is hard to get across in text. Sometimes it takes a picture to convey what words are unable to.
