Srinivasa Ramanujan was an Indian mathematician born in 1887 who made pioneering contributions to the theory of numbers, including the properties of the partition function. He was largely self-taught and demonstrated extraordinary mathematical abilities from a young age. Some of his most famous discoveries include properties of Bernoulli numbers and identifying 1729 as a number expressible as the sum of two cubes in two different ways, now known as the Hardy-Ramanujan number. Despite lacking formal training, he was recognized for his genius and received support to study at the University of Cambridge.

1. Srinivasa Ramanujan, born December 22,
1887, India and died in Kumbakonamc at 26
April, 1920, He got Education from University
of Cambridge 1916.His father was , K. Srinivasa
Iyengar and hs mother was Komalatammal,
Indian mathematician whose contributions to
the theory of numbers include pioneering
discoveries of the properties of
the partition function.
His collection of thousands of theorems, many
presented with only the briefest of proofs and
with no material newer than 1860, aroused his
genius. Having verified the results in Carr’s
book, Ramanujan went beyond it, developing
his own theorems and ideas. In 1903 he secured
a scholarship to the University of Madras but
lost it the following year because he neglected
all other studies in pursuit of mathematics and
Ramanujan wrote his first formal paper for the
Journal on the properties of Bernoulli numbers.
One property he discovered was that the
denominators (sequence A027642 in the
OEIS) of the fractions of Bernoulli numbers
are always divisible by six and he called
1729 his magic number because Ramanujan

2. said that it was not. 1729, the Hardy-
Ramanujan Number, is the smallest number
which can be expressed as the sum of two
different cubes in two different ways. 1729 is
the sum of the cubes of 10 and 9 - cube of 10 is
1000 and cube of 9 is 729; adding the two
numbers results in 1729. .
