#### A person who lived for a little over 32 years, Ramanujam was born in Kumbhakonam, the famous temple town in the Cauvery River delta.

**In his Dreams**

#### Ramanujam attributed the mathematical formulae that he came up with, to Namagiri Thayar, the Goddess of Namakkal temple.

#### He often mentioned that it was Goddess Namagiri who came to him in his dreams and gave answers to his mathematical problems.

**From Wife**

#### The wife of Ramanujam, Janakiammal has an interesting input about her husband.

#### Ramanujam used to feverishly do all his basic calculations on a black slate. This was the norm of every student in India then.

#### She says, “Ramanujam did his calculations on a hand held slate, then transferred the final results to his note books, erasing the slate.”

#### Thus we have few clues as to how he arrived at these equations, and there is no doubt that they are true.

#### This is expressed by the mathematics historian George Gheverghese Joseph in his book ‘The Crest of the Peacock’, Page 11.

#### His work notes and formulae that he arrived at are available in his now famous notebooks.

**To Cambridge University**

#### When Ramanujam was working as a Clerk in Madras Port Trust, he sent some of his mathematical workings to Prof. G H Hardy of Cambridge University.

#### Ongoing through the notes, Prof G H Hardy felt that here was an absolute genius at work.

#### Prof Hardy invited Ramanujam to the Cambridge University.

#### Ramanujam spent 6 to 7 years in Cambridge. The work that Ramanujam did then along with Hardy has now become a part of the legend of Mathematics.

#### The mathematical formula that Ramanujam came up has been used as algorithms in modern computer systems.

#### Unfortunately, due to severe cold weather of England, Ramanujam who was more used to the tropical climate of Kumbhakonam, could not acclimatize and picked up an illness. The illness grew from bad to worse and he sailed back to India.

#### A sick and sad Ramanujam returned to Madras on April 2^{nd} 1919. He passed away on 26^{th} April, 1920 at Chetpet in Madras.
