In India, the National Mathematics Day is observed on December 22 every year. It is celebrated in order to honor the birth anniversary of the famous mathematician Sir Srinivasa Ramanujan. He was the world famous mathematician who made remarkable contributions in different fields and branches of the subject mathematics.
Srinivasa Ramanujan (December 22, 1887 to April 26, 1920) was an Indian mathematician.
He made important contribution to mathematical analysis, number theory and continued fractions.
- Ramanujan was born in Erode, Madras, India. In high school he devoured books on mathematics and discovered advanced theorems.
- In 1903 he read A Synopsis of Elementary Results in Pure and Applied Mathematics by G.S.Carr and it was instrumental in his future discoveries.
- When he was seventeen he developed the Bernoulli numbers and calculated the Euler-Mascheroni constant to 15 decimal places.
- In 1904 he graduated from town Higher Secondary School and received the K. Ranganatha Rao prize in mathematics.
- He received a scholarship to the Government Arts College but failed to study any subject but mathematics and lost his scholarship.
- In 1905 he enrolled in another college but again failed to study the other required subjects and left without a degree.
- Although he had no degree his mathematical studies impressed V. Ramaswamy Aiyer who was the founder of the Indian Mathematical Society.
- V. Ramaswamy Aiyer gave him letters of introduction to R. Ramachandra Rao who gave him financial backing while he continued his research in mathematics.
- In 1912 he was hired in the office of the Chief Accountant of the Madras Port Trust.
- He began to send his mathematical papers to the famous British mathematician,G.H. Hardy.
- Hardy recognized and encouraged Ramanujan’s brilliance in mathematics and presented his papers to his colleagues at Trinity College.
- On March 17, 1914 Ramanujan left India for England.
- He spent five years in Cambridge and was eventually awarded a PhD in mathematics.
- He received many awards for his work and in 1917 he was elected to the London Mathematical Society.
- In 1918 he was elected Fellow of the Royal Society “for his investigation in Elliptic function and the Theory of Numbers.”
- He was diagnosed with tuberculosis and a severe vitamin deficiency but later medical studies point to a case of undiagnosed hepatic amoebiasis.
