**National Mathematics Day**– National Mathematics Day is observed on 22 December every year to mark the birth anniversary of legendary Indian mathematician, Srinivasa Ramanujan. The day aims to create awareness of the development of mathematics and its importance in the growth of humanity.

Many scholars have made valuable contributions to mathematics such as **Aryabhata, Mahavir, Brahmagupta, and **Bhaskara II are known as mathematicians. all these showed genius signs. Ramanujan was born in 1887 in Erode, Tamil Nadu. he performed excellent performance at trigonometry and created various theorems.

He also contributed to the infinite series, fractions, mathematical analysis, and number theory. that’s why to remember his contribution, India celebrates Mathematics Day on 22nd December to mark the birth anniversary of Ramanujan.

**National Mathematics Day: History**

The 2012 Indian stamp was issued for Srinivasa Ramanujan. The Indian government designated 22 December to be celebrated as National Mathematics Day each year to mark the birth anniversary of the Indian mathematician Srinivasa Ramanujan.

On 26 December 2011, Prime Minister Manmohan Singh introduced the day at Madras University, to mark the 125th birth anniversary of the Indian mathematician Srinivasa Ramanujan. On this occasion, Prime Minister Shri Manmohan Singh also announced that 2012 would be celebrated as the National Mathematics Year.

Since then, India’s National Mathematics Day has been celebrated on 22 December every year with numerous educational events held at schools and universities across the country. In 2017, the day’s significance was taken by the opening of the Ramanujan Math Park in Kuppam, in Chittoor, Andhra Pradesh. National Mathematics Day is observed in all schools and universities in India.

**Know About Srinivasa Ramanujan**

Srinivasa Ramanujan was born on 22nd December 1887 in Erode, Tamil Nadu. He achieved knowledge in Trigonometry at the age of 12. He for a copy of George Shoobridge Carr’s Synopsis of Elementary Results in Pure and Applied Mathematics at the age of 15.

In 1911 Ramanujan released the first of his papers in the Journal of the Indian Mathematical Society. In 1916, He was honoured with the B.A. Degree by research of Cambridge University. He was appointed a Fellow of the Royal Society of London in February 1918.

He solved mathematics questions and worked on various types of theorems. He died on 26th April 1920 at the age of 32.

**History Behind Ramanujan Number – 1729**

1729 is also known as the Ramanujan Number. When the Indian mathematician, Ramanujan was living in England, he once got very ill. Prof. Hardy met Ramanujan in the hospital and stated to Ramanujan that 1729 seemed to be a very dull number, and hoped it wouldn’t turn out to be an unfavourable omen.

However, 1729 is the smallest number which can be noted in the form of a sum of cubes of two numbers in two ways such as 1729=1³+12³=9³+10³. Since then the number 1729 has been called Ramanujan’s number.

**Srinivasa Ramanujan Quotes**

- “An equation for me has no meaning, unless it expresses a thought of God.”
- “To preserve my brains I want food and this is now my first consideration. Any sympathetic letter from you will be helpful to me here to get a scholarship.”
- “I beg to introduce myself to you as a clerk in the Accounts Department of the Port Trust Office at Madras on a salary of only £20 per annum. I am now about 23 years of age. After leaving school I have been employing the spare time at my disposal to work at Mathematics”
- “No, it is a very interesting number, it is the smallest number expressible as a sum of two cubes in two different ways”
- “While asleep, I had an unusual experience. There was a red screen formed by flowing blood, as it were. I was observing it. Suddenly a hand began to write on the screen. I became all attention. That hand wrote a number of elliptic integrals. They stuck to my mind. As soon as I woke up, I committed them to writing.”
