Quotation

1729. No, Hardy. It is a very interesting number. It is the smallest number expressible as the sum of two cubes in two different ways. (Known as the Hardy–Ramanujan number: 1729 = 1^3 + 12^3 = 9^3 + 10^3, from wikipedia.) === Hardy remembering Ramanujan: It is difficult to put into words... What I owe Ramanujan. His originality has been a constant source of suggestion to me ever since I first met him. And his death is one of the worst blows I have ever felt. But now I say to myself when I'm depressed, and I find myself forced to listen to tiresome and pompous people, "Well, I've done something you could never have done. "I have collaborated with both Littlewood and Ramanujan "on something like equal terms."
