Some work, found string of Ramnujan’s original and sometimes unconventional have inspired vast amounts of further research and have applications in fields as diverse as crystallography and theory. A common anecdote about Ramanujan during his last days relates how Hardy arrived at Ramanujan's house in a cab numbered 1729. He then mentioned to Ramanujan that the number seemed to be very uninteresting. In reply, Ramanujan is said to have remarked immediately that, in fact, the number was an extremely interesting number mathematically, since it was the smallest number representable as a sum of two cubes in two different ways. This derivation is shown below: 1729 can be expressed as 13 + 123 or as 93 + 103 The number 1729 is now referred to as the Hardy-Ramanujan number and numbers with is particular property are also referred to as the "taxicab numbers". There are estimations that Ramanujan speculated upon or provided proofs for over 3,000 such theorems, identities and equations. Hardy, on the other, lived on till the age of 70. When asked in an interview what his greatest contribution to mathematics was, Hardy unhesitatingly replied that it was the discovery of Ramanujan, and even called their collaboration "the one romantic incident in my life". After Ramanujan died, Hardy strongly urged that Ramanujan's notebooks be edited and published. Ramanujan’s extraordinary abilities and achievements can be best summed up a remark made by Michio Kaku, a Japanese American theoretical physicist, tenured professor and co-creator of string field theory: “Srinivasa Ramanujan was the strangest man in all of mathematics, probably in the entire history of science. He has been compared to a bursting supernova, illuminating the darkest, most profound corners of mathematics, before being tragically struck down by tuberculosis at the age of 33.” 13
