Ramanujan: Letters & Commentaries
This book by Berndt and Ranking has been 'lying' on the bookshelf for quite sometime. Ramanujan story is an inspiring story. He taught us, that, even without formal training, we can excel in our effort- as long as we set our heart and mind to achieve excellence. I first came across the name 'Ramanujan' when I watched the movie Good Will Hunting. Ramanujan was born in Southern India. he lived a short life (1887-1920) and is believed to have died from hepatic amoebasis. Although he excelled in all his school subjects, his subsequent passion for mathematics made him neglect his other studies. While attending a government college, he ran away mid-way his studies. He attended another college, but he failed all his subjects other than mathematics. Ramanujan was mostly self-educated. Sometimes he would 'rediscover' some theorem which have been discovered by other mathematicians. G S Carr's Synopsis of elementary results in pure mathematics was an early influence, and this book provided the only model on how Ramanujan presented his arguments. His first job was a temporary clerk job in Madras. With the influence of his uncle, he was provided some leisure time for mathematics. He was discovered by G.H Hardy (or rather he 'discover' Hardy through Hardy's 1910 book-Orders of infinity) who brought him to England and introduced him to the circle of 'formal' mathematicians and rigour of 'formal' mathematics. His notebook dubbed the LOST NOTEBOOK was discovered in 1976 at Trinity College, Cambridge. Between 1903 and 1914, Ramanujan filled three notebooks with mathematical formulas and relationships. He did most of his computations and experimentation on a slate, since he could not afford to buy papers. He would then erase all his intermediate work and recording only his final results. Hence, his notebook and other papers would contain thousands of formulas,most of them without proof or even a hint of their sources. Due to his illness, he was comitted to many nursing homes in England between 1917 and 1919. He returned to India on March 1919 a sick man, and was attended (for his illness) in several different places in India. He died on April 26, 1920. Many of his assertions have yet to be proved.

Ramanujan's thinking was ahead of his time.
