Dear All, Indian Prime Minister Manmohan Singh paid tribute to mathematician Srinivasa Ramanujan (1887- 1920), on the occasion of 125th birth anniversary. He announced that his birthday - December 22 - would be a National Mathematics Day. Srinivasa Ramanujan (22 December 1887 – 26 April 1920) was an Indian mathematician, who made extraordinary contributions to mathematical analysis, number theory, infinite series, and continued fractions. Ramanujan independently compiled nearly 3900 results (mostly identities and equations). His work continues to inspire mathematicians even today! Srinivasa Ramanujan, born into a poor Brahmin family at Erode on Dec. 22, 1887, attended school in nearby Kumbakonam. By the time he was 13, he could solve unaided every problem in Loney's Trigonometry, and at 14 he obtained the theorems for the sine and the cosine that had been anticipated by L. Euler. Ramanujan became so absorbed in mathematics that when he entered the local governm...
