I got hold of the fire chief here in Los Angeles, and I said, “At what temperature does book paper catch fire and burn?” He said, “Just a moment, be right back.” He came back and said, “451 Fahrenheit.” And I thought, “Oh, that’s beautiful.” That’s absolutely beautiful. It’s perfect. So I reversed it, and said Fahrenheit 451, and there you have the title. And if we start using Celsius in the next few years, I will be severely disappointed.
