I just happened to go back to "The Man Who Knew Infinity" yesterday and noticed the date. It's a fine book, written with uncommon skill.
It tells the story of the genius Srinivasa Ramanujan who grew up poor and poorly educated in India; he sent a letter full of mathematics to G. H. Hardy, the greatest British mathematician of his time. Hardy spent the evening with his collaborator John Edensor Littlewood, and they sat together and marveled at the formulas they were seeing.
Ramanujan was a true genius. "Years later, Hardy would contrive an informal scale of natural mathematical ability on which he assigned himself a 25 and Littlewood a 30. To David Hilbert, the most eminent mathematician of his day, he assigned an 80. To Ramanujan he gave 100." Hardy could compare him only with Euler and Jacobi.
Ramanujan was very sickly and died young. Once Hardy took a taxi to the hospital and said that the cab he took was numbered 1729 and said he thought it was a very boring number. Ramanujan said, no, no, it's a very interesting number; notice that 1729=1 cubed +12 cubed =9 cubed +10 cubed and that it was the smallest number you can write as the sum of two cubes in two different ways. Wow.
Anyway, today is a great day in mathematics.
