## The Man Who Knew Infinity: A Life of the Genius Ramanujan by Robert Kanigel

The tale of a relationship between a young Indian mathematics genius, Ramanujan, and his tutor at Cambridge University, G.H. Hardy, in the years before World War I. Through their eyes the reader is taken on a journey through numbers theory. Ramanujan would regularly telescope 12 steps of logic into two - the effect is said to be like Dr Watson in the train of some argument by Sherlock Holmes. The language of symbols and infinitely large (and small) regions of mathematics should be rendered with clarity for the general reader.## Srinivasa Ramanujan Biography In Hindi - About S Ramanujan - Mathematicians - Motivational Video

## Srinivasa Ramanujan

Though he had almost no formal training in pure mathematics , he made substantial contributions to mathematical analysis , number theory , infinite series , and continued fractions , including solutions to mathematical problems then considered unsolvable. Ramanujan initially developed his own mathematical research in isolation: "He tried to interest the leading professional mathematicians in his work, but failed for the most part. What he had to show them was too novel, too unfamiliar, and additionally presented in unusual ways; they could not be bothered". Hardy at the University of Cambridge , England. Recognizing Ramanujan's work as extraordinary, Hardy arranged for him to travel to Cambridge. In his notes, Ramanujan had produced groundbreaking new theorems , including some that Hardy said had "defeated him and his colleagues completely", in addition to rediscovering recently proven but highly advanced results.

Srinivasa Ramanujan is an Indian mathematician who is known for his extraordinary work in the field of Mathematics. His research work was ahead of his time, despite receiving no formal training in maths. In the beginning years, he developed his theories in isolation. He contributed to number of theories, mathematical analysis, continued fractions, infinite series and even to solutions of problems that were considered unsolvable. His genius was recognised during his school days as well when he completed an advanced book on trigonometry by S. By his late teens, he had already studied the Bernoulli numbers and also calculated the Euler-Mascheroni constant up to 15 decimal places.

Like Sophie Germain , he received no formal education in mathematics but made important contributions to advancement of mathematics.

## Who Was Srinivasa Ramanujan?

Two years later Ramanujan began a correspondence with British mathematician G. Hardy that resulted in a five-year-long mentorship for Ramanujan at Cambridge, where he published numerous papers on his work and received a B. After contracting tuberculosis, Ramanujan returned to India, where he died in at 32 years of age. Srinivasa Ramanujan was born on December 22, , in Erode, India, a small village in the southern part of the country. Shortly after this birth, his family moved to Kumbakonam, where his father worked as a clerk in a cloth shop. Ramanujan attended the local grammar school and high school and early on demonstrated an affinity for mathematics. When he was 15, he obtained an out-of-date book called A Synopsis of Elementary Results in Pure and Applied Mathematics , Ramanujan set about feverishly and obsessively studying its thousands of theorems before moving on to formulate many of his own.

His father, K. Srinivasa Iyengar was a clerk while his mother, Komalatammal performed as a singer, in a temple. At the age of 10, in , Ramanujan attended the high school in Kumbakonam Town. There he discovered his intelligence in the field of mathematics and by his independent study of books from the school library; Ramanujan increased his knowledge and skills. At age of just 12 years, he had developed understanding of trigonometry and was able to solve cubic equations and arithmetic and geometric series as well. Among all of the mathematical literature Ramanujan went through, a book by George Shoobridge Carr , titled as A Synopsis of Elementary Results in Pure and Applied Mathematics , written in , proved to be the primary medium that laid him onto the path of becoming a great mathematician.
