## Srinivasa Ramanujan – Short Essay 1.

**Srinivasa**** Ramanujan was a famous Indian **Mathematician who lived during the **British rule** in India. He was born on 22 December 1877.

He was not a formal mathematician but made his part to factorial stuff, number theory and continued fractions.

He also solved many unsolvable mathematical problems. In the beginning, he developed his own research by living in Isolation.

**About Ramanujan:**

- Ramanujan’s was born in a
**Tamil family.** - His Father K. Srinivasawas a clerk in a sari shop.
- Mother was a religious housewife and also sang at the temple.
- Ramanujan’ s Family home is now a
- Ramanujan joined school in
**October 1892**, and later moved to Madras School. - At the age of 11, he formally started mathematics. He took less than three years to master mathematics. And, at 14 years of age, he was already getting certificates and awards.
- Srinivasa received a scholarship study
**at Government Arts College, Kumbakonam**.

**Early life**

Ramanujan was known to have been a brilliant student even in his early school years. Once he was introduced to formal mathematics, he thrived on that knowledge and went on to more and more complex details. He won many awards in his school years for mathematics. Professor Ramaswamy introduced him to the mathematics department at the University of Madras.

After his marriage, he took up a job as a researcher at Madras University. He graduated to working as a clerk based on his work in mathematics that he continually upgraded.

**Later work**

Ramanujan sent his work to University College, London and to Cambridge University, where it was noticed, and arrangement made to have him travel to London. Ramanujan initially refused to travel abroad but later accepted.

Ramanujan studied Mathematics in Cambridge and after five years was awarded a Bachelor in Science degree, later converted to a Ph.D.

He became an elected member of the London Mathematical Society in 1917. He was the first India to be elected a Fellow of the Trinity College, Cambridge in 1918.

Ramanujan had been dealing with health problems since childhood. However, around 1918, he was diagnosed with tuberculosis after which he returned to his family in India and died in 1920.

His exceptional genius in mathematics had already been acknowledged while in Cambridge, and his work still lives on to make every Indian proud.

**Contribution:**

- In 1904 Ramanujan provided a method to calculate Bernoulli numbers and calculated the Euler–Mascheroni constant up to 15 decimal places.
- He was also awarded by the K. Ranganatha Rao prize from school Headmaster.
- Founded
**The Indian Mathematical Society.** - He solved the problems to find the values of differential
**Hardy–Ramanujan number 1729**is also his**famous work.**

**Conclusion:**

The man died at an early age of 32. The reason for death was Tuberculosis and an extreme deficiency of vitamin C.

## Srinivasa Ramanujan – Short Essay 2

**Srinivasa Ramanujan** is one of the **greatest mathematicians in the world**, and he is known for the great work that he did in his field. He made a lot of his theories very popular in the world, and that is why his theories still get used in lots of countries.

He was **born on 22 ^{nd} December 1887 in Erode**, and he gets known by a number of contributions he made in the theory of numbers. It is very shocking for a lot of people, but initially, Ramanujan

**never studied mathematics**. He studied mathematics in the latter half of his education and became an expert of it.

He studied a few books written by international mathematicians, and after a few years, he made his own several theories on mathematics.

He was **very poor**, and he did various researches in poor circumstances only, but he later got supported by Ramachandra Rao and his clerical job due to which he became able to learn more and invent several new studies on mathematics.

In **1914, he won a scholarship to England** and studied under Godfrey hardy. He did not only studied hard but invented various other theories which made Hardy his fan as well. He surprised every teacher with the knowledge of mathematics that he had because he never knew the modern techniques of the maths, but he still did better than a lot of professors and researchers at that time.

He invented a lot of theories, and the most famous ones are as followed: Ramanujan constant, Mock theta functions, Ramanujan conjecture, Ramanujan prime, Ramanujan theta function, Ramanujan’s sum, Ramanujan’s seta series, etc. He also won the award of fellow of the royal society.

He worked for a very short period as he **died at the age of 32** only, but his theories are still alive in a lot of people’s brains and textbooks. So, this was all about the best mathematician in the country Srinivasa Ramanujan.
