**About :**

- Mathematics can be described as the study of quantity, numbers and space. In many ways, mathematics can be regarded as the
**mother science**. Mathematics is an essential tool in many fields, including natural science, engineering, medicine, and the social sciences. Applied mathematics, the branch of mathematics concerned with application of mathematical knowledge to other fields such as physics, economics and biology, inspires and makes use of new mathematical discoveries and has also led to the development of entirely new mathematical disciplines, such as statistics and game theory. - The national workshop on Ancient Indian Mathematics with special reference to Vedic Mathematics and Astronomy, passed a resolution on 25
^{th}September, 2010 recommending that 22^{nd}December i.e. the birth anniversary of mathematics legend**Srinivasa Ramanujan**be observed as ‘National Mathematics Day‘ every year. The Government of India has since resolved to celebrate the said day, as the National Mathematics Day every year so as to focus the attention of people to mathematics education and its applications. National Mathematics Day is dedicated to Srinivasa Ramanujan (22^{nd}December, 1887 – 26^{th}April, 1920) an Indian mathematician and autodidact, who with almost no formal training in pure mathematics, made substantial contribution to mathematical analysis, number theory, infinite series and continued fractions. Ramanujan is placed in the same league as legendary mathematicians such as**Euler**,**Gauss**,**Newton**and**Archimedes**. - Born and raised in
**Erode**,**Tamil Nadu**, Ramanujan first encountered formal mathematics at the age of 10, demonstrated a natural ability and mastered books on advanced trigonometry and even discovered theorems of his own. By 17, he conducted his own mathematical research on Bernoulli numbers and the Euler-Mascheroni constant. In 1912-1913, he sent samples of his theorems to three academics at the ‘University of Cambridge‘. Only**G.H. Hardy**recognized the brilliance of his work subsequently inviting him to visit and work with him at**Cambridge**. - During his short lifetime, he independently compiled nearly 3900 results, both original and highly unconventional, such as the Ramanujan Prime and the Ramanujan Theta Function that inspired a vast amount of further research. Recently, his formulae have found applications in crystallography and string theory. The
**Ramanujan Journal**, an international publication, was

launched to publish work in all areas of mathematics influenced by his work. - The 125
^{th}birth anniversary celebrations of Ramanujan commenced on 22^{nd}December, 2011 and would be closing on the 22^{nd}December, 2012. Celebration of National Mathematics Day every year will connect Ramanujan‘s life and work to the people of India and thereby inspire a large section of young Indians. The year 2012 is being celebrated as the National Mathematical Year. **Text :**Based on the material received from the proponent.
