ROGER BOWLEY: The number is 1,729, which is known as a Hardy-Ramanujan number. JAMES GRIME: In mathematical circles, this is a famous number. So there was a famous mathematician, an Indian mathematician called Ramanujan. Now, he started life quite humbly. He was a clerk in India, and he had no formal training in mathematics. However, he worked as a mathematician in his spare time. He had proven some things. He sent these proofs to Cambridge. A lot of the Cambridge mathematicians just ignored it, but one Cambridge mathematician, Geoffrey Hardy, recognized something in this. Now, the proofs that he did were actually things that were already well known. But he invited Ramanujan over to England and started to work with him. And Ramanujan is no...
