Paul Erdős has passed on to us Hardy‘s personal ratings of mathematicians. Suppose that we rate mathematicians on the basis of pure talent on a scale from 0 to 100, **Hardy gave himself a score of 25, Littlewood 30, Hilbert 80 and Ramanujan 100**.

- Bruce C. Berndt in
*Ramanujan’s Notebooks : Part I*(1994), “Introduction”, p. 14

The formulae (1.10) – (1.13) are on a different level and obviously both difficult and deep… (1.10) – (1.12) defeated me completely; **I had never seen anything in the least like them before. A single look at them is enough to show that they could only be written by a mathematician of the highest class. They must be true because, if they were not true, no one would have the imagination to invent them.**

- G. H. Hardy as quoted by Edward O. Wilson,
*Biophilia*(2009)

**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, like Riemann before him.

*Hyperspace : A Scientific Odyssey Through Parallel Universes, Time Warps, and the Tenth Dimension*(1995), p. 172

**The great advances in mathematics have not been made by logic but by creative imagination.** The title of mathematician can scarcely be denied to Ramanajan who hardly gave any proofs of the many theorems which he enumerated.
