I remembered something the Professor had said: "The mathematical order is beautiful precisely because it has no effect on the real world. Life isn't going to be easier, nor is anyone going to make a fortune, just because they know something about prime numbers. Of course, lots of mathematical discoveries have practical applications, no matter how esoteric they may seem . . . But those things aren't the goal of mathematics. The only goal is to discover the truth." The professor always said the word truth in the same tone as the word mathematics.
