The Man Who Knew Infinity

At the turn of the twentieth century, Srinivasa Ramanujan is a struggling and indigent citizen in the city of Madras in India working at menial jobs at the edge of poverty. While performing his menial labour, his employers notice that he seems to have exceptional skills in mathematics and they begin to make use of him for rudimentary accounting tasks. It becomes equally clear to his employers, who are college-educated, that Ramanujan's mathematical insights exceed the simple accounting tasks they are assigning to him and soon they encourage him to make his personal writings in mathematics available to the general public and to start to contact professors of mathematics at universities by writing to them. One such letter is sent to G.H. Hardy, a famous mathematician at University of Cambridge, who begins to take a special interest in Ramanujan.
