“Note to academics: Aristarchus' track record of astronomical research would probably have guaranteed him tenure somewhere, if tenure had been invented. His stack of reprints included measuring the distances of the Moon and Sun.”

“Obviously, I have arguments with people on the pitch, with all the emotions.”
