Srinivasa Ramanujan

Srinivasa Ramanujan (born December 22, 1887, India, Erode, 26 April 1920, Kumbakonam), Indian mathematician, his theory to digital theory, including breakthrough discoveries about the nature of the distribution function Contribution

When he was fifteen he summarized the summary of pure mathematics and applied mathematics results by George Shawbridge in two volumes. (1880-1886) Many of them provide the most concise evidence, and this collection of thousands of theorems without new materials since 1860 caused his genius. After verifying the results of Carr's book, Ramanujan passed that and developed his own theorem and idea. In 1903, he received a scholarship from the University of Madras, but he ignored all other studies pursuing mathematics, so he lost it in the second year.

Ramanujin continues to work, has no jobs, and lives in the poorest environment. After marriage in 1909, he began searching for permanent employment opportunities and reached a climax in an interview with government official Ramachandra Rao. Ramanujan's mathematical strength gave a deep impression to Rao who was supporting his research in the past, but Ramanujan who did not want to exist in charity organizations was clerical in the Madras Port Trust I won the position.

In 1911, Ramanu Jin published his first paper to Indian Mathematical Society magazine. His genius gained recognition slowly and in 1913 he communicated with the English mathematician Godfrey H. Hardy and received a special scholarship from Madras University and a subsidy from the University of Cambridge Trinity College. Ramanujin overcame his religious objections and traveled to England in 1914 when Hardy made him a tutor and worked with him in several studies.

The mathematical knowledge of Ramanujan (the majority of the data he designed for him) is amazing. He is almost completely unaware of modern development of mathematics, but his mastery of continuous score does not match any living mathematician. He studied the Riemann series, the elliptic integral, the hypergeometric series, the functional equation of the zeta function, and his own divergent series theory. On the other hand, he does not know anything about double periodic function, classical theory of quadratic form, or Cauchy 's theorem and has only the most ambiguous concepts about the composition of mathematical proofs. Very exciting, but many of his theorems on prime number are wrong.

In the UK, Ramanujan, in particular numerical division (the number of ways in which positive integers can be expressed as the sum of positive integers, for example 4 can be expressed as 4, 3 + 1, 2 + 2, 2 + 1 You can make it even more). + 1, 1 + 1 + 1 + 1). His paper was published in English and European journals and was elected to the Royal Society of London in 1918. In 1917, Ramanujan infected tuberculosis, but his condition improved further, and he returned to India in 1919. He died in the second year and is generally unknown to the world, but from Leonhard Euler (without accompanying person from 1707) -83) and Karl Jacoby (1804-51), a very excellent genius It is considered by mathematicians to be. Ramanujan left three notes and one page (also called "lost note"). It contained a lot of unpublished results, and mathematicians did not validate for a long time after his death.

Srinivasa Ramanujan embodies the term "genius". For mathematicians he is a rich and real story. Ramanujin grew up in rural India at the end of the 19th century and had few opportunities to hone his ingenious mathematical skills. He used the hard shell artifacts he can get. Once, he encountered primitive and obsolete textbooks and drew profound mathematical theorems from this simple manuscript - many of them were not known to the best mathematicians of the time. Ramanujan sent his manuscript to England, and everyone rejected them except for the famous mathematical professor GH Hardy at the Trinity College in Cambridge. Even Hardy was ready to launch Rama Nakin's work until he noticed what he read was very deep. Hardy invited Ramanuzin to Cambridge. These two people form the most unlikely alliance. His life is shortened by illness, but Ramanujin is safe as a great mathematical legacy.

The story of Srinivasa Ramanujan is widely published compared to other contemporary geniuses. Kanigel follows the relationship between a young Indian mathematician and his leader GH. Hardy, Cambridge, they announced some of the most original work of the last century. However, under the figures there is a hidden moving story. Goodwin spent ten years studying the book and showed it. It explains the life of Abraham Lincoln, but the focus is on his relationship with his leadership style and the five outstanding figures of the cabinet. It is a historical record, but text flows in a rich and attractive story. Competitor team is a long and useful reading. We can all learn something from Lincoln.
