SRINIVASA RAMANUJAN (FATHER OF MATHEMATICS IN INDIA) INVENTIONS & DISCOVERIES, CONTRIBUTION TO MATHEMATICS

By | November 12, 2018

Srinivasa Ramanujan is perhaps the greatest mathematician from India and counted among the top contributors to the subject of mathematics also called as father of mathematics in India. National mathematics day (December 22) is celebrated to commemorate his birthday.

Revered by maths for decades, his works are still an inspiration for young aspirants in the field that’s the reason he is called as father of mathematics. He is one of the important people in top 10 Indian inventions and discoveries.

srinivasa Ramanujan inventions and discoveries

He invented lots of theorems and derivations the most important invention in mathematics are a Hardy-Ramanujan number, the Ramanujan Conjecture, Ramanujan prime, Ramanujan-Soldner constant, Ramanujan theta function, Ramanujan’s sum, Rogers-Ramanujan identities, Ramanujan’s master theorem, divergent series.

He invented over 400 original theorems by himself. His works have earned him a great honor and often counted among the famous mathematicians like Gauss, Euler, and Jacobi. Srinivasa Ramanujan demonstrated his mathematical genius even as a 10-year-old.

His memory for mathematical formulas and constants seems to have been boundless: he amazed classmates with his ability to recite the values of irrational numbers like π, e, and √2 to as many decimal places as they asked for.

srinivasa Ramanujan contribution to mathematics

srinivasa Ramanujan contributions to the analytical theory of numbers, elliptic functions, continued fractions and infinity. In 1900 Ramanujan work on his own on mathematics summing geometric and arithmetic series. Ramanujan invented nearly 120 theorems on imply divisibility properties of the partition function.

Euler’s constant

By 1904 Ramanujam and Euler researching about the Euler’s Constant. Ramanujan investigated the series (1/n) and calculated Euler’s constant to 15 decimal places.

Partition of whole numbers

He motivated by the Partition of whole numbers and developed a formula for the partition of any number, which can be made to yield the required result by a series of successive approximation for Example 3=3+0=1+2=1+1+1.

Ramanujan number

1729 is called as a Ramanujan number. It is the smaller number which can be expressed as the sum of two cubes in two different ways- 1729 = 13 + 123 = 93 + 103.

#4 RAMANUJAN AWARDED B.A BY RESEARCH OF CAMBRIDGE UNIVERSITY

After spending a year at the University of Madras and working on his papers, Srinivasa Ramanujan finally arrived in England in 1914. He collaborated with G.H.Hardy and Littlewood and published a number of papers on highly composite numbers, Elliptic functions and refined a number of his early works to perfection. He was awarded B.A degree (called Ph.D. after 1920) by research for his work on highly composite numbers.

#5 G.H.HARDY’S IMPRESSION ABOUT RAMANUJAN’S WORK

Undeterred by the response from University College London, Ramanujan sent his works to Cambridge with the help of some friends. G.H.Hardy who worked in Trinity College went through Ramanujan’s work and was both impressed as well as grew doubtful due to the nature and depth of his work which he did not expect from an Indian without any formal education. G.H.Hardy invited Ramanujan to join Trinity College but he refused to leave the country and was admitted to the University of Madras and offered a scholarship of Rs.75 per month. The scholarship helped him to concentrate on his work which was awarded following his letter to G.H.Hardy stating To preserve my brains I want food and this is my first consideration.

Indian Mathematical Society’s founder member Ramachandra Rao along with few admirers including E.W.Middlemast presented Ramanujan’s work to University College London. M.J.M.Hill found his works riddles with holes as well as lacking the foundation owing to his informal approach to the subject. He was therefore not offered an admission to the college.
