Srinivasa Ramanujan was a renowned Indian mathematician who made extraordinary contributions to mathematical analysis, number theory, infinite series, and continued fractions despite having no formal training in pure mathematics. He was born in 1887 in India and showed an extraordinary aptitude for mathematics from a young age. Ramanujan struggled to find recognition for his mathematical genius in India but eventually his notebooks were sent to the English mathematician G.H. Hardy, who helped Ramanujan gain admission to Cambridge University. There, Ramanujan continued his groundbreaking mathematical research before falling ill and returning to India, where he passed away in 1920 at the young age of 32. Ramanujan made substantial contributions to mathematical fields and is regarded as one of the

Srinivasa Ramanujan was a great Indian
mathematician . He was born on 22nd December
1887 in Erode (Tamil Nadu) during British
Government .His full name was Srinivasa Iyenger
Ramanujan . His father name was Kuppuswamy
Srinivasa Iyenger and his mother’s name was
Komalatammal. He was enrolled in the Town
higher Secondary School from 1897-1904 , Wherehe encountered formal mathematics for the first Time.
By age 11, he had exhausted the mathematical knowledge of two college students who were lodgers at his home .He was latter lent a book on advanced
trigonometry written by S.L.Loney. He completely mastered on this book by the age of 13 and discovered
Sophisticated theorems on his own . In July 1909,
Ramanujan married S.Janaki Ammal , who was then
Just 10 years old . The Cambridge mathematician
G.H. Hardy arranged for Ramanujan to visit Trinity
College in Cambridge .Ramanujan arrived in Cambridge in 1914 and He completed his graduation from Cambridge University ,London . He made a lot of his theories which are very popular in the world and That is why His theories still get used in lots of countries . He wrote many books Comprising his theories and formulas . He is famous for his contribution to number theory and infinite Series .His birthday is celebrated as National Mathematics Day in India every year .He was died on 26th April 1920 ,at the age of 32 years in Madras . He Worked for a very short period but his teaching are Still alive in many people’s mind and text books .His Contribution in the Field of mathematics has been immense and will be remembered forever.
During his short life, Ramanujan independently compiled nearly 3,900 results (mostly identities and equations).[6] Many were completely novel; his original and highly unconventional results, such as the Ramanujan prime, the Ramanujan theta function, partition formulae and mock theta functions, have opened entire new areas of work and inspired a vast amount of further research.[7] Of his thousands of results, all but a dozen or two have now been proven correct.[8] The Ramanujan Journal, a scientific journal, was established to publish work in all areas of mathematics influenced by Ramanujan,[9] and his notebooks—containing summaries of his published and unpublished results—have been analysed and studied for decades since his death as a source of new mathematical ideas. As late as 2012, researchers continued to discover that mere comments in his writings about "simple properties" and "similar outputs" for certain findings were themselves profound and subtle number theory results that remained unsuspected until nearly a century after his death.[10][11] He became one of the youngest Fellows of the Royal Society and only the second Indian member, and the first Indian to be elected a Fellow of Trinity College, Cambridge. Of his original letters, Hardy stated that a single look was enough to show they could have been written only by a mathematician of the highest Ramanujan.

Tutored college students
6. ATTENTION FROM MATHEMATICIANS
Met V. Ramaswamy Aiyer, founder of
Indian Mathematical Society
I was struck by the extraordinary
mathematical results contained in it [the
notebooks]. I had no mind to smother his
genius by an appointment in the lowest
rungs of the revenue department
Introduced to R. Ramachandra Rao,
secretary of the Indian Mathematical
Society
Impressed by Ramanujan but doubted his
integrity.
Continued Mathematical Research with
Rao’s financial help
R.Ramachandra Rao
7. Published his work in Journal of Indian Mathematical Society
First problem which he posed
He then formulated an equation to solve the infinitely nested
radicals problem.
Wrote his 1st formal paper for the journal on the properties
of Bernoulli Numbers
8. In early 1912 he got a job in the Madras Accountant
Generals office with a salary of Rs 20 per month.
Later he applied for a position under the Chief
Accountant of the Madras Port Trust
Accepted as a Class III, Grade IV accounting clerk
making 30 rupees per month
Spent spare time doing Mathematical Research
9. CONTACTING ENGLISH
MATHEMATICIANS
M. J. M. Hill of University College London argued
that though Ramanujan had taste for Mathematics
he lacked the proper educational background and
foundation
He refused to take Ramanujan as student
But gave him professional advice on his work
10. INTRODUCTION WITH
G.H.HARDY
G.H. Hardy was an academician at Cambridge University
He was a prominent English mathematician, known for his
achievements in number theory and mathematical analysis.
Later on Ramanujan wrote to G.H.Hardy
Hardy recognised some of his formulae but other “seemed
scarcely possible to believe”. Some of them were –
Relating to infinite series -
12. LIFE IN ENGLAND
Ramanujan boarded the S.S.Nevasa on 17 March 1914
and arrived in London on 14th April
Ramanujan began working with Hardy and Littlewood
Hardy received 120 theorems from him in 1st 2 letters
but there were many more results in his notebook
After working with Ramanujan Littlewood
commented, "I can believe that he's at least a Jacobi”
Hardy said he "can compare him only with [Leonhard]
Euler or Jacobi”
Ramanujan spent nearly 5 years in Cambridge
13. Awarded BA degree by research
(later called PhD) in March 1916
6.12.1917 – Elected to London
Mathematical Society
Became a ‘Fellow of The Royal
Society’ in 1918
Became the first Indian to be elected
a Fellow of Trinity College,
Cambridge
RAMANUJAN’S HONOURS
14. ILLNESS & RETURN TO INDIA
Ramanujan's health worsened in England
Diagnosed with Tuberculosis and Vitamin
deficiency
Returned to Kumbakonam in 1919 and died soon
thereafter at the age of 32
In 1994 Dr. D.A.B. Young analysed his records and
concluded he had hepatic amoebiasis
15. PERSONALITY AND SPIRITUAL LIFE
A person with a somewhat shy and quiet disposition
A dignified man with pleasant manners
Ramanujan credited his success to his family Goddess,
Namagiri of Namakkal
He claimed to receive visions of scrolls of complex
mathematical content unfolding before his eyes
"An equation for me has no meaning, unless it
represents a thought of God.”
16. RAMANUJAN’S NOTEBOOKS
Recorded his work in 4 notebooks of loose
leaf paper
Results were written without derivation
Mathematician Bruce C. Berndt says that
Ramanujan was able to make the proofs
but chose not to.
Might have worked on slate
Or may be influenced by G.S Carr’s book
which stated results without proofs
Mathematicians such as Hardy, G.N.
Watson, B.M. Wilson and Bruce Berndt
created papers from his work
17. RAMANUJAN - HARDY NUMBER
1729
Hardy arrived in a cab numbered 1729
He commented that the number was
uninteresting
Instantly Ramanujan claimed that it was the
smallest natural number which can be written as
sum of cubes in 2 ways
18. OTHER MATHEMATICIANS’ VIEWS
OF RAMANUJAN
J.H. Hardy was highly impressed by Ramanujan
Hardy said that the solutions were "arrived at by
a process of mingled argument, intuition, and
induction, of which he was entirely unable to
give any coherent account”
On the basis of pure talent Hardy rated himself a
score of 25 out of 100, J.E. Littlewood 30, David
Hilbert 80 and Ramanujan 100 !
Physicist Jayant Narlikar appreciated
Ramanujan’s discoveries
19. RECOGNITION
Tamil Nadu celebrates 22 December as ‘State IT Day’
Stamp released by the Govt. in 1962
22nd December celebrated as Ramanujan Day in Govt
Arts College, Kumbakonam
