Srinivasa Ramanujan Biography
Early Years
Ramanujan (literally “younger brother of Rama”) was born in Erode, Tamil Nadu on 22 December 1887 to a Tamil Brahmin Iyengar family. His father, Kuppuswamy Srinivasa Iyengar, worked as a clerk in a sari store, and his mother, Komalatammal, was a housewife and temple singer. They resided in a modest traditional dwelling on Sarangapani Sannidhi Street in Kumbakonam. At the age of one and a half, Ramanujan’s mother gave birth to Sadagopan, who died less than three months later. Ramanujan contracted smallpox in December 1889 and recovered.
He relocated with his mother to the home of her parents in Kanchipuram, close to Madras (now Chennai). On October 1, 1892, Ramanujan enrolled in the local elementary school, Kangayan Primary School. When his paternal grandfather passed away, he returned to his By the age of 11, Ramanujan had expended the mathematical knowledge of two college students. Later, he was given S. L. Loney’s book on advanced trigonometry, which he mastered by the age of 13.
Throughout his academic career, he received merit certificates and academic awards, and he assisted the school in assigning approximately 1,200 students to 35 instructors. He completed examinations in half the allotted time and demonstrated knowledge of geometry and infinite series. In 1903, he obtained a copy of A Synopsis of Elementary Results in Pure and Applied Mathematics from a friend’s library and independently developed and researched the Bernoulli numbers and calculated the Euler–Mascheroni constant to 15 decimal places. His contemporaries reported that they “rarely understood him” and “held him in reverent awe.” In 1904, when he graduated from Town High School, he was awarded the K.

Contributions
- Ramanujan compiled nearly 3,900 equation and identity results. His infinite series for pi was one of his most valued discoveries. This series is the foundation for numerous algorithms in use today. He provided a variety of formulas for calculating the digits of pi.
- The development of game theory received a substantial boost as a result of his innovative solutions to a number of difficult mathematical problems. His contribution to game theory is founded solely on his intuition, natural ability, and mathematical prowess.
- The number 1729 is renowned as the Ramanujan number. It equals the sum of the cubes of 10 and 9. For example, 1729 is the sum of 1000 (the cube of 10) and 729 (the cube of 9) cubes. As the sum of these two cubes, it is the smallest number that can be expressed in two different forms. 1729 is a natural number that follows 1728 and comes before 1730.
- The contributions of Ramanujan span numerous areas of mathematics, such as complex analysis, number theory, infinite series, and fractions.
Personal Life
Ramanujan married Janaki (Janakiammal; 21 March 1899 – 13 April 1994) on 14 July 1909, a year after his mother had chosen her for him. Following his marriage, Ramanujan developed a hydrocele testis, which was treatable with a standard surgical procedure. Following a successful operation, Ramanujan sought employment and tutored students at Presidency College. Late in 1910, Ramanujan became ill once more and instructed his friend R. Radhakrishna Iyer to pass over his notebooks to Professor Singaravelu Mudaliar or to Professor Edward B. Ross of the Madras Christian College.
In 1912, Ramanujan moved to a home on Saiva Muthaiah Mudali Street in George Town, Madras with his wife and mother. After obtaining a research position at Madras University in May 1913, Ramanujan relocated to Triplicane with his family.
Srinivasa Ramanujan was an Indian mathematician who made significant contributions to the theory of numbers, including the first-ever discoveries of the partition function’s properties.
Srinivasa Ramanujan Death
On April 26, 1920, Srinivasa Ramanujan, one of the most renowned mathematicians in history, passed away at the age of 32. His death was caused by a significant case of tuberculosis that had affected his health for several years.
Following are some interesting details about him:
- He was a mathematical savant, as he had no formal training in the subject but nonetheless made exceptional discoveries in mathematics.
- In school, Ramanujan had few friends because his classmates rarely comprehended him and were in awe of his mathematical prowess.
- As a young man, he was unable to graduate from college because he did not pass his fine arts courses.
- As the paper was costly, Ramanujan frequently used slates to jot down the results of his derivations.
- 13-year-old Ramanujan could solve Loney’s Trigonometry problems without assistance.
- In Europe, he encountered moderate prejudice. He returned to India because the climate did not suit him.
- Due to a humorous incident, the number ‘1729’ is now known as the Hardy-Ramanujam number in his honour.
