We Indians are not too great but we have some GREATEST personalities like Aryabhatta -- Who gave the world ZERO This is a small presentation on life history of Srinivasa Ramanujan. Please LIKE and SHARE.

4. BORN 22 December 1887
PLACE OF BIRTH ERODE, TAMILNADU
FATHER K. Srinivasa Iyengar
MOTHER Komalat Ammal
WIFE Janaki Ammal
SIBLINGS Sadagopan

5. &

6. HE STARTED HIS SCHOOLING IN 1892. INITIALLY HE
DID NOT LIKE SCHOOL THOUGH HE SOON STARTED
EXCELLING HIS STUDIES, ESPECIALLY MATHEMATICS.
IN 1897 HE PASSED HIS EXAMS
IN ENGLISH, TAMIL, GEOGRAPHY
AND ARITHMETIC WITH THE
HIGHEST SCORES IN HIS
DISTRICT.

7. ONCE HIS TEACHER SAID THAT WHEN ZERO IS
DIVIDED BY ANY NUMBER, THE RESULT IS
ZERO, RAMANUJAN IMMEDIATELY ASKED HIS
TEACHER WHEATHER ZERO DIVIDED BY ZERO
GIVES ZERO.

8. HE PASSED HIS PRIMARY
EXAMINATIONS AND STOOD
FIRST IN THE DISTRICT AT
TOWN HIGH SCHOOL-
KUMBAKONAM IN1898
HE ALSO MASTERED
ADVANCED
TRIGONOMETRY WRITTEN
BY S.L. LONEY AT THE
AGE OF 13 YEARS.

9. IN HIGH SCHOOL HE
DEVOURED BOOKS ON
MATHEMATICS AND
DISCOVERED
ADVANCED
THEOREMS.

10. AT THE AGE OF 16 HE GOT HIS
HANDS ON A BOOK CALLED ‘A
SYNOPSIS OF ELEMENTARY
RESULTS IN PURE AND APPLIED
MATHEMATICS’ BY G.S. CARR
WHICH WAS A COLLECTION OF
5,000 THEOREMS. HE WAS
THOROUGHLY FASCINATED BY
THE BOOK AND SPENT MONTHS
STUDYING IT IN DETAIL. THIS
BOOK IS CREDITED TO HAVE
AWAKENED THE MATHEMATICAL
GENIUS IN HIM

11. BY THE TIME HE WAS 17, HE HAD INDEPENDENTLY
DEVELOPED AND INVESTIGATED THE BERNOULLI
NUMBERS AND HAD CALCULATED THE EULER–
MASCHERONI CONSTANT UP TO 15 DECIMAL
PLACES. HE WAS NOW NO LONGER INTERESTED IN
ANY OTHER SUBJECT, AND TOTALLY IMMERSED
HIMSELF IN THE STUDY OF MATHEMATICS ONLY.

12. HE WAS GRADUATED FROM
TOWN HIGH SECONDARY SCHOOL
IN 1904 AND WAS AWARDED
THE K. RANGANATHA RAO PRIZE
FOR MATHEMATICS BY THE
SCHOOL'S HEADMASTER,
KRISHNASWAMI IYER.

14. RAMANUJAN MADE SUBSTANTIAL
CONTRIBUTIONS TO THE
ANALYTICAL THEORY OF NUMBERS
AND WORKED ON ELLIPTIC FUNCTIONS,
CONTINUED FRACTIONS AND INFINITE. IN 1900
HE BEGAN TO WORK ON HIS OWN ON
MATHEMATICS SUMMING GEOMETRIC AND
ARITHMETIC SERIES.

15. HE WORKED ON DIVERGENT SERIES.
HE SENT 120 THEOREMS ON SIMPLE
DIVISIBILITY PROPERTIES OF THE
PARTITION FUNCTION.

16. PARTITION OF WHOLE NUMBERS IS ANOTHER
SIMILAR PROBLEM THAT CAPTURED
RAMANUJAN’S ATTENTION.
SUBSEQUENTLY RAMANUJAN DEVELOPED A
FORMULA FOR THE PARTITION OF ANY
NUMBER, WHICH CAN BE MADE TO YIELD THE
REQUIRED RESULT BY A SERIES OF
SUCCESSIVE APPROXIMATION.
EXAMPLE 3=3+0=1+2=1+1+1.

17. GOLDBACH’S CONJECTURE
IT IS ONE OF THE MOST IMPORTANT
ILLUSTRATIONS OF RAMANUJAN CONTRIBUTION
TOWARDS THE PROOF OF THE CONJECTURE.
THE STATEMENT IS EVERY EVEN INTEGER
GREATER THAT TWO IS THE SUM OF TWO
PRIMES.
THAT IS, 6=3+3
RAMANUJAN AND HIS ASSOCIATES HAD
SHOWED THAT EVERY LARGE INTEGER COULD
BE WRITTEN AS THE SUM OF AT MOST FOUR
(EXAMPLE: 43=2+5+17+19).

18. RAMANUJAN STUDIED THE HIGHLY
COMPOSITE NUMBERS ALSO
WHICH ARE RECOGNIZED AS THE
OPPOSITE OF PRIME NUMBERS.
HE STUDIED THEIR STRUCTURE,
DISTRIBUTION AND SPECIAL
FORMS
NUMBERS

19. FERMAT THEOREM
HE ALSO DID CONSIDERABLE WORK ON
THE UNRESOLVED FERMAT THEOREM,
WHICH STATES THAT A PRIME NUMBER
OF THE FORM 4m+1 IS THE SUM OF
TWO SQUARES.

20. RAMANUJAN’S NUMBER
1729 IS A FAMOUS RAMANUJAN
NUMBER.
IT IS THE SMALLEST NUMBER
WHICH CAN BE EXPRESSED AS
THE SUM OF TWO CUBES IN
TWO DIFFERENT WAYS
1729 = 13 + 123 = 93 + 103

21. CUBIC EQUATIONS AND QUADRATIC
EQUATIONS
RAMANUJAN SHOWED HOW TO SOLVE
CUBIC EQUATIONS.
IN 1902 HE WENT ON TO FIND HIS OWN
METHOD TO SOLVE THE QUADRATIC.

22. EULER’S CONSTANT
BY 1904 RAMANUJAN HAD
BEGAN TO UNDERTAKE DEEP
RESEARCH.
HE INVESTIGATED THE SERIES
(1/n) AND CALCULATED EULER’S
CONSTANT UPTO 15 DECIMAL
PLACES.
