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

#### Kumbakonam, the rice bowl of Tamil Nadu has been famous for many things, from temples to rice and now for the aromatic Kumbakonam Degree Coffee.

#### But, the greatest son of Kumbakonam is the mathematician, Srinivasa Ramanujan.

**In his Dreams**

#### Ramanujan 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 Ramanujan, Janakiammal has an interesting input about her husband.

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

#### She says, “Ramanujan 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 Ramanujan 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 Ramanujan to the Cambridge University.

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

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

#### Unfortunately, due to severe cold weather of England, Ramanujan 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 Ramanujan returned to Madras on April 2^{nd} 1919. He passed away on 26^{th} April, 1920 at Chetpet in Madras.

*Ganitham*

*Ganitham*

#### Srinivasa Ramanujan belonged to an illustrious lineage of mathematicians that India has offered to the world starting from Boudhayana, Apastambha, Aryabhatta, Varahamihira, Brahma Gupta, Bhaskaracharya, Madhava and a galaxy of others.

#### All these illustrious people through the ages specialized in this field of *Ganitham*, the Indian term for mathematics.

#### The word *Ganitham* has in it the phrase *Gana*, meaning weighty, heavy. The field of mathematics has always been weighty and heavy.

#### The Lord of Mathematics in Indian tradition is Ganesha, Ganapathy. The term *Gana* also means numbers.

**Lord Ganesha, the lord of Mathematics**

**An illustrious lineage**

#### India has had an illustrious lineage of people who excelled in *Ganitham*.

#### Srinivasa Ramanujan is one among this illustrious lineage.

#### Today in our midst, we have another illustrious mathematician of Indian origin settled in USA, Prof Srinivasa Vardhan who is an Abel Laureate.

**Abel Laureate**

#### It is to be noted that in mathematics there is no Nobel Prize as Alfred Nobel did not like Maths.

#### The same Norwegian Academy which confers the Nobel Prize year after year has instituted an award for mathematics, equal to novel prize in the name of their Norweigian mathematician, Niels Henrik Abel.

**Niels Henrik Abel**

#### It would be nice if the Indian government could institute an international award in the name of Srinivasa Ramanujan for the lineage that India has given to world in the field of *Ganitham*, mathematics.

**Mathematics – Crest of Peacock**

#### Mathematics among the sciences is given a high place, like the crest of a peacock among its colored plum, in its ancient treatises. *Vedanta Jyothisa*, an ancient treatise on mathematics and astronomy mentions this.

**The Man who saw Infinity**

#### In the last decade or so, there has been a spurt of interest on Srinivasa Ramanujan. Books are being written and films are being made on this great man who saw infinity.

**The Man who knew Infinity, Book**

#### We need to sustain this interest to encourage more Indians to take up pure mathematics.
