In our journey through school, we have come across many differing mathematical practices contributed by pioneers such as Pythagoras, Fermat, Gauss, Descartes etc. Post a write up about the life and impact of your favourite Mathematician.

22 December - Remembering Srinivasa Ramanujan(22 December 1887 - 26 April 1920)A compilation of information from different sites.Srinivasa Ramanujanwas one of India's greatest mathematical geniuses. He made substantial contributions to the analytical theory of numbers and worked onelliptic 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 (now Chennai). 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 as a clerk in a cloth merchant's shop.Some of his works include:Get pi fastIn his notebooks, Ramanujan wrote down 17 ways to represent 1/pias aninfinite series. Series representations have been known for centuries. For example, theGregory-Leibnizseries, discovered in the 17th century is pi/4 = 1 - ⅓ + ⅕ -1/7 + … However, this series converges extremely slowly; it takes more than 600 terms to settle down at 3.14, let alone the rest of the number. Ramanujan came up with something much more elaborate that got to 1/pi faster: 1/pi = (sqrt(8)/9801) * (1103 + 659832/24591257856 + …). This series gets you to 3.141592 after the first term and adds 8 correct digits per term thereafter. This series was used in 1985 to calculate pi to more than 17 million digits even though it hadn’t yet been proven.Taxicab numbersIn a famous anecdote, Mathematician G Hardy took a cab to visit Ramanujan. When he got there, he told Ramanujan that the cab’s number, 1729, was “rather a dull one.” Ramanujan said, “No, it is a very interesting number. It is the smallest number expressible as a sum of two cubes in two different ways. That is, 1729 = 1^3 + 12^3 = 9^3 + 10^3. This number is now called the Hardy-Ramanujan number, and the smallest numbers that can be expressed as the sum of two cubes in n different ways have been dubbed taxicab numbers. The next number in the sequence, the smallest number that can be expressed as the sum of two cubes in three different ways, is 87,539,319.There is another article showing how Ramanujan was so close to finding a counter-example of Fermat's last theory.
