SRI SATHYA SAI COLLEGE FOR WOMEN ANANT ………….A ROAD TO INFINITY 2015 Department of Mathematics Happy Pi DaY Most people have heard of the mathematical constant Pi (π), and know that it’s roughly 3.14. Taking inspiration from these three digits, March 14 (3/14 in the US date format) is celebrated as international Pi day,first marked by US physicist LarryShaw in1988. The number π is a universal constant that is ubiquitous across mathematics. In fact, it is an understatement to call it “universal,” because π lives not only in this universe but in any conceivable universe. It existed even prior to the Big Bang. It is permanent and unchanging.This year brought a unique opportunity to by marking Pi Day correct to nine decimal places on March 14, 2015, at 9.26am 53sec – corresponding to 3.141592653, the first 10 digits of Pi. Some interesting Facts About Pi Pi is a irrational number which means it cannot be accurately represented as a/b where a, b are integer, this was proved by Johann Lambert in1761.tThis means its decimal expansion is never ending with no repeated pattern. Pi is also a transcendental number i.e., a number that cannot be reduced algebraically (more accurately a number that is not the root of any non-zero polynomial equation with rational coefficients) The proof that Pi is transcendental was found in 1882 by German mathematician Ferdinand Lindemann Some people spend a lifetime calculating π. Ludolph van Ceulen did, and got it to a 35 decimals, 3.14159265358979323846264338327950 288, that also in the 17th century when calculations were done by hand. The current record for calculating digits of Pi is 13.3 trillion decimal digits. There are thousands of formulae to calculate Pi,the most remarkable is the one given by Indian mathematician Ramanujan in 1941. Those who have missed this ear coincidence of Pi day will have to wait for 100 years to experience it next time!

The finding has implications for our understanding of how harmful or beneficial immune responses can be manipulated for better health. The research team used mathematics and computer modeling to understand how complex signaling impacts the size of the response by key infectionfighting immune system called T cells. T cells are important for launching specific immune responses against invading microbes, as well as eliminating some cancer cells. .
