On Ramanujan’s 133rd Birth Anniversary: Famous constants related to Srinivasa Ramanujan

1. Almost Integer (Ramanujan’s Constant) Ramanujan’s constant is the transcendental number , which is an almost integer, in that it is very close to an integer: This number was discovered in 1859 by the mathematician Charles Hermite. In a 1975 April Fools Day article in the Scientific American magazine,

Apery's constant

Apery’s constant is defined as , where represents the Euler’s zeta function. First lets us define the zeta function. Zeta function is defined as where is a complex number. The story of Apery’s constant began with the famous Basel problem and Euler’s solution of it. At the

Pi Day Doodle by Google in 2010 As most of us know, March 14th every year is celebrated by mathematicians all over the world as Day. The reason for this is quite simple: March 14 is written as 3-14 in the American style of writing dates and as the value

Pi Day

Pi Day is an annual celebration commemorating the mathematical constant π (pi). Pi Day is observed on March 14 (or 3/14 in month/day date format), since 3, 1 and 4 are the three most significant digits of π in the decimal form. In 2009, the United States House

Approximations to Pi by the Kerala School of Mathematics

Estimating the value of $$pi$$ (the ratio between the circumference and diameter of a circle) has been the favourite pass time of mathematicians from antiquity to the modern age. Most of the mathematicians in the ancient days used the procedure of inscribing and circumscribing the circle by polygons of a

The Ubiquitous Pi

Beauty of Mathematics

The Ubiquitous Pi

Let’s begin by Quoting William Schaff: ‘probably no symbol in mathematics has evoked as much mystery, romanticism, misconception and human interest as the number $$pi$$….’ Geometry and trigonometry For any circle with radius r and diameter d (= 2r), the circumference is πd and the area is πr2. Further, π
