In honour of Ramanujan's accomplishments, the Indian government declared National Mathematics Day in 2012. Prime Minister Manmohan Singh had first spoken about National Mathematics Day on 26 December 2011 at Madras University, to mark the 125th birth anniversary of Srinivasa Ramanujan, as per Akashvani News.

Schools and universities commemorate the day by hosting activities including quizzes, lectures, seminars, exhibitions, and competitions centred on mathematics.

In order to encourage students to learn more about mathematics, schools and institutions all over India commemorate National Mathematics Day with a variety of educational activities. It is a day to honour Mr Ramanujan's legacy and inspire upcoming generations to carry on his mathematical contributions.

About Srinivasa Ramanujan

Indian mathematician Srinivasa Ramanujan Iyengar was active in the early 20th century. He made significant contributions to mathematical analysis, number theory, infinite series, and continuing fractions despite having virtually little formal experience in pure mathematics. He also solved mathematical problems that were thought to be intractable at the time.

In 1913, he started writing to the English mathematician G. H. Hardy at the University of Cambridge, England, in an attempt to find mathematicians who could better comprehend his work. Hardy made arrangements for Ramanujan to visit Cambridge after realising how remarkable his work was.

In his notes, Hardy said Ramanujan produced groundbreaking theorems. Hardy admitted that some of Ramanujan’s work “defeated me completely." “I had never seen anything in the least like them before,” he said, per Quanta Magazine.
