Srinivasa Ramanujan
1887-1920
The man who knew Infinity
Srinivasa Ramanujan was born on 22nd Dec 1887, in the town of Erode,
Tamil Nadu, India. He was a self-taught pure mathematician. He made
substantial contributions to the analytical theory of numbers and worked
on elliptic functions, continued fractions and infinite series. His father, K.
Srinivasa Iyengar was an accounting clerk for a clothing merchant and his
mother, Komalatammal, earned a small amount of money as a singer at
the local temple. His family were Brahmins and they were very poor.
Every year, National Mathematics
day is celebrated on the birth
anniversary of Srinivasa
Ramanujan. This tradition started
on the 125th birth anniversary of
Ramanujan by our former Prime
Minister Dr. Manmohan Singh on
22nd Dec 2012.
Its main objective is to raise
awareness among people about
the importance of mathematics
for the development of humanity.
He showed early signs of brilliance
during his school. His main source of
inspiration and expertise
became Synopsis of elementary results
in pure mathematics by George S.
Carr. He could afford only a small
amount of paper, so, he did most of
his work on slate with chalk.
Ramanujan sent nine pages of his mathematical work to an eminent pure
mathematician at the University of Cambridge – G. H. Hardy in January 1913. When Hardy went to see Ramanujan when he was
ill at Putney. He rod in taxi cab number 1729 &
remarked that the number seemed rather dull to
him and hoped it was not an unfavourable omen.
To which Ramanujan said, it is a very interesting
number, it is the smallest number expressible as the
sum of 2 cubes in 2 differrent ways.
𝟏𝟕𝟐𝟗 = 𝟏𝟑
+ 𝟏𝟐𝟑
= 𝟗𝟑
+ 𝟏𝟎𝟑
Also called Taxi cab Number
In July 1909, Ramanujan
married S. Janaki Ammal, who
was then just 10 years old. The
couple began sharing a home in
1912. When he left for
Cambridge, her wife lived with
his family.
In April 1914, he left for Cambridge where two years later, he was awarded the equivalent of a Ph.D.
for his work – a mere formality. The winter weather in England made him ill for a time. In 1917, he
was diagnosed with tuberculosis. In February 1919, his health seemed to have recovered sufficiently
for him to return to India, but sadly he lived for only one more year.
Srinivasa Ramanujan died aged 32 in Madras on April 26, 1920. Sadly, some of Ramanujan’s Brahmin
relatives refused to attend his funeral because he had traveled overseas.

Hardy-Ramanujan Number
Hardy reviewed the papers with J. E. Littlewood, another eminent Cambridge
mathematician, telling Littlewood they had been written by either a crank or a genius,
but he wasn’t quite sure which. After spending two and a half hours poring over the
outlandishly original work, the mathematicians came to a conclusion. They were
looking at the papers of a mathematical genius.
Hardy was eager for Ramanujan to move to
Cambridge, but in accordance with his
Brahmin beliefs, Ramanujan refused to travel
overseas. Instead, an arrangement was made
to fund two years of work at the University of
Madras. During this time, Ramanujan’s
mother had a dream in which the goddess
Namagiri told her she should give her son
permission to go to Cambridge, and this she
did. Her decision led to a chaos in the family.
