Ramanujan was an orthodox Brahmin and so was a strict vegetarian. His religion should have prevented him from travelling but this difficulty was overcome, partly by the work of eville who was a colleague of Hardy 's at Trinity college and who met with Ramanujan while lecturing in India. Ramanujan sailed from India on It was a calm voyage except for three days on which Ramanujan was seasick. He arrived in London on was met by neville. After four days in London they went to cambridge and Ramanujan spent a couple of weeks in neville's home before moving into rooms in Trinity college on 30th April. Right from the beginning, however, he had problems with his diet. The outbreak of World War I made obtaining special items of food harder and it was not long before ramanujan had health problems.
Srinivasa ramanujan - mathematician, biography
I have made a special investigation of divergent series in general and the results I get are termed by the local mathematicians as 'startling'. Hardy, together with Littlewood, studied the long list of unproved theorems which Ramanujan enclosed with his letter. On 8 February he replied to ramanujan 3, the letter beginning:- i was exceedingly interested by your letter and by the theorems which you state. You will however understand that, before i can judge properly of the value of what you have done, it is essential that I should see proofs of some of your assertions. Your results seem to me to fall into roughly three classes: (1) there are a number of results that are already known, or easily deducible from known theorems; (2) there are results which, so far as i know, are new and interesting, but interesting rather. Ramanujan was delighted with Hardy 's reply and when he wrote again he said 8 :- i have found a friend in you who views thesis my labours sympathetically. I am already a half starving man. To preserve my brains I want food and this is my first consideration. Any sympathetic letter from you will be helpful to me here to get a scholarship either from the university of from the government. Indeed the University of Madras did give ramanujan a scholarship in may 1913 for two years and, in 1914, hardy brought Ramanujan to Trinity college, cambridge, to begin an extraordinary collaboration. Setting this up was not an easy matter.
Hill replied in a fairly encouraging way but showed that he had failed to understand Ramanujan's results on divergent series. The recommendation to ramanujan dates that he read Bromwich 's Theory of infinite series did not please ramanujan much. Ramanujan wrote to obson and aker trying to interest them in his results but neither replied. In January 1913 Ramanujan wrote to ardy having seen a copy of his 1910 book orders of infinity. In Ramanujan's letter to hardy he introduced himself and his work 10 :- i have had no university education but I have undergone the ordinary school course. After leaving school I have been employing the spare time at my disposal to work at mathematics. I have not trodden through the conventional regular course which is followed in a university course, but i am striking out a new path for myself.
I have, however, been devoting all my time to mathematics and developing the subject. Despite the fact that he had no university education, ramanujan was clearly well known to the university mathematicians in Madras for, with his letter of application, ramanujan included a reference from iddlemast who was the Professor of Mathematics at The Presidency college in Madras. Middlemast, a graduate of St John's College, cambridge, wrote 3 :- i can strongly recommend the applicant. He is a young man of quite exceptional capacity in mathematics and especially in work relating to numbers. He has a natural aptitude for computation and is very quick at figure work. On the strength of the recommendation Ramanujan was appointed to the post of clerk and began his duties on Ramanujan was quite lucky to have a number of people working round him with a training in mathematics. In fact the Chief Accountant for the madras Port Trust, iyar, was trained as a mathematician and published a paper On the distribution of primes in 1913 on Ramanujan's work. The professor of civil engineering at the madras Engineering College griffith was also interested in Ramanujan's abilities and, having been educated at University college london, knew the professor of mathematics there, namely hill. He wrote to hill on 12 november 1912 sending some of Ramanujan's work and a copy of his 1911 paper on Bernoulli numbers.
Indian Mathematical Society who had helped start the mathematics library. He writes in 30 :-, a short uncouth figure, stout, unshaven, not over clean, with one conspicuous feature-shining eyes- walked in with a frayed notebook festival under his arm. He was miserably poor. He opened his book and began to explain some of his discoveries. I saw quite at once that there was something out of the way; but my knowledge did not permit me to judge whether he talked sense or nonsense.
I asked him what he wanted. He said he wanted a pittance to live on so that he might pursue his researches. Ramachandra rao told him to return to madras and he tried, unsuccessfully, to arrange a scholarship for Ramanujan. In 1912 Ramanujan applied for the post of clerk in the accounts section of the madras Port Trust. In his letter of application he wrote 3 :-, i have passed the matriculation Examination and studied up to the first Arts but was prevented from pursuing my studies further owing to several untoward circumstances.
Continuing his mathematical work ramanujan studied continued fractions and divergent series in 1908. At this stage he became seriously ill again and underwent an operation in April 1909 after which he took him some considerable time to recover. He married on when his mother arranged for him to marry a ten year old girl s janaki ammal. Ramanujan did not live with his wife, however, until she was twelve years old. Ramanujan continued to develop his mathematical ideas and began to pose problems and solve problems in the. Journal of the Indian Mathematical Society.
He devoloped relations between elliptic modular equations in 1910. After publication of a brilliant research paper on Bernoulli numbers in 1911 in the. Journal of the Indian Mathematical Society he gained recognition for his work. Despite his lack of a university education, he was becoming well known in the madras area as a mathematical genius. In 1911 Ramanujan approached the founder of the. Indian Mathematical Society for advice on a job. After this he was appointed to his first job, a temporary post in the Accountant General's Office in Madras. It was then suggested that he approach Ramachandra rao who was a collector at Nellore. Ramachandra rao was a founder member of the.

In 1906 Ramanujan went to madras where he entered Pachaiyappa's College. His aim was to pass the first Arts examination which would allow him to be admitted to the University parts of Madras. He attended lectures at Pachaiyappa's College but became ill after three months study. He took the first Arts examination after having left the course. He passed in mathematics but failed all his other subjects and therefore failed the examination. This meant that he could not enter the University of Madras. In the following years he worked on mathematics developing his own ideas without any help and without any real idea of the then current research topics other than that provided by carr's book.
Ramanujan, on the strength of his good school work, was given a scholarship to the government College in Kumbakonam which he entered in 1904. However the following year his scholarship was not renewed because ramanujan devoted more and more of his time to mathematics and neglected his other subjects. Without money he was soon in difficulties and, without telling his parents, he ran away to the town of vizagapatnam about 650 km north of Madras. He continued his mathematical work, however, and at this time he worked on hypergeometric series and investigated relations between integrals and series. He was to discover later that he had been studying elliptic functions.
In 1900 he began to work on his own on mathematics summing geometric and arithmetic series. Ramanujan was shown how to solve cubic equations in 1902 and he went on to find his own method to solve the quartic. The following year, not knowing that the quintic could not be solved by radicals, he tried (and of course failed) to solve the quintic. It was in the town High School that Ramanujan came across a mathematics book by arr called. Synopsis of elementary results in pure mathematics. This book, with its very concise style, allowed Ramanujan to teach himself mathematics, but the style of the book was to have a rather unfortunate effect on the way ramanujan was later to write down mathematics since it provided the only model that he had. The book contained theorems, formulae and short proofs. It also contained an index to papers on pure mathematics which had been published father's in the european journals of learned Societies during the first half of the 19th century. The book, published in 1856, was of course well out of date by the time ramanujan used.
Srinivasa ramanujan: in celebration of the centenary
Srinivasa ramanujan was one of India's greatest mathematical geniuses. He made substantial contributions to the analytical theory of numbers and worked on elliptic functions, continued fractions, and infinite series. Ramanujan was born in his grandmother's house in Erode, a small village about 400 km southwest of Madras. When Ramanujan was a year old his mother took him to the town of Kumbakonam, about 160 km nearer Madras. His father worked in Kumbakonam writings as a clerk in a cloth merchant's shop. In December 1889 he contracted smallpox. When he was nearly five years old, ramanujan entered the primary school in Kumbakonam although he would attend several different primary schools before entering the town High School in Kumbakonam in January 1898. At the town High School, ramanujan was to do well in all his school subjects and showed himself an able all round scholar.
