## Srinivasa Ramanujan: The Greatest Indian Mathematician

Born on the **22nd of December** in the year **1887**, nobody knew that a small boy from India will contribute so much to the field of Mathematics. Ramanujan was an intelligent child since his childhood, but he was stuck in the British ruled India, and never had the liberty to attend a formal college. Most of his life he spent scribbling and doodling different theories until one day a British servant saw his talent and mailed some of his work to the professors in England. After that, he was called to the English state to pursue his **Ph.D.** degree at the **Trinity** **College**, where he made many contributions to the subject and was also honored by becoming a **Fellow of the Royal Society**.

England did not bode him well and he suffered from **tuberculosis** in his late 20s, and unfortunately, he had to lose his life in his early 30s. He died on the **26th of April, 1920** when he was **32 years old**. This article will shed light on some of the major contributions of Ramanujan in mathematics that shook the world.

**Infinite series for Pi**

Ramanujan was the first man to find a formula that would determine the infinite series of **pi**. Finding the approximation of pi numbers had been one of the toughest tasks in the history of mathematics, which was fortunately solved by none other than Ramanujan.

**Mock Theta Functions**

It is a topic residing under the modular forms of mathematics, and Ramanujan made elaborations on this subject that have helped many other mathematicians.

**Ramanujan Number**

There is a number known after the mathematician, i.e., **1729**, and is the summation of the cubes of **10 **and **9**.

**Circle Method**

The 20th century had many problems in the mathematics line, one among them was **Waring's Conjecture**, these problems were not getting solved until Ramanujan along with his partner research Hardy produced the **Circle Method **that would lead to help the mathematicians solve many problems. The role of the Circle method was to provide the approximation value to the partitions of numbers exceeding 200.

**Theta Function**

Theta Functions were broadly given by Ramanujan after famous **German** mathematicians **Jacobi** gave theta functions in his name. But Ramanujan's Theta Functions were up to date and helped in solving problems in different dimensions like **String Theory**, **Superstring Theory**, and **M-Theory**.

Even though Ramanujan did not receive a very good formal education, he succeeded a lot in understanding mathematics on a whole other level. His contributions to mathematics are broad and impressive. We are proud to have someone like Ramanujan represent our country in the world in mathematics.
