5. A thought of 7 years Old
Ramanujan
Once his teacher said that when
zero is divided by any number,
the result is zero, Ramanujan
immediately asked his teacher,
whether zero divided by zero
gives zero; This shows early
signs of his genius!

7. Adulthood
He was a self-taught Mathematician.
He was really good at Maths so when
he took his exam, he passed in Maths,
but failed in other subjects because of
his disinterest. So , he couldn’t enter
the university of Madras for further
studies.
He was married with a nine years old
girl named Janaki Ammal, when he
was 22 but he did not live with his wife
till she reached the age of 12.
Since he showed extraordinary talent
by himself, people around him helped
to take his achievements known to the
other Internationally renowned
mathematicians .
8. He was invited to England to
improve his works by G.H.Hardy
and J.E Littlewood, who were
great mathematicians.
Hardy and Ramanujan had two
opposite personalities. As Hardy
was an atheist and believes
mathematical proof and analysis,
Ramanujan was a deeply
religious guy and he believed in
his trustworthy intuition .
He was the first elected
Mathematician from India to the
London Mathematical society
and he became a Fellow of the
Royal society.

9. Recognition of his
Genius
Initially, G. H. Hardy
thought that the works of
Ramanujan were fraud
because most of them were
impossible to believe. But
eventually ,they were
convinced and interested in
his talent.

26. Ramanujan and Hardy
arrived at Ramanujan’s
residence in a cab
number 1729.
Hardy commented that
the number 1729 seemed
to be unintresting.
Ramanujan said that it is
a very intresting
mathematical number.

27. The smallest natural number can
be represented in two different
ways as a sum of two cubes:
1729=13 +123
=93 +103
It is also incidentally the product
of three prime numbers

28. Largest known similar
number is
885623890831
=75113 +77303
=87593+59783
Ramanujan was indeed a
friend of numbers.

29. CONTRIBUTION TO THE
THEOREY OF PARTITIONS
A partition of N No. of
a natural PARTITIONS
number ‘n’ is a 1 1
sequence of 2 2
3 3
non- 4 5
decreasing 5 7
positive 6 11
integers whose
sum is ‘n’.

30. Example:
For N=4,PARTITIONS are
4=4
=1+3
=2+2
=1+1+2
=1+1+1+1
P(4)=5,Whether P is a partition function
The highest highly composite
number listed by Ramanujan is
6746328388800
Having 10080 factors
