India marks National Mathematics Day in memory of Ramanujan
National Mathematics Day is celebrated on December 22, since 2012, after former Prime Minister Manmohan Singh made the declaration to pay tribute to Srinivasa Ramanujan on his birth anniversary. Born into a Tamil family in Erode in 1887, the self-taught mathematician mastered Trigonometry by the age of 12 and independently compiled over 3,900 results before succumbing to ill-health, aged 32.
