WHAT? How can 1+2+3+… be -1/12 ???
Ramanujan’s first letter to Hardy: To the above letter, Ramanujan attached at least 11 pages of technical results from a number of areas of mathematics (of which 2 were lost). The sum of all positive numbers is -1/12 is one of the many results on those pages. But how can 1+2+3+… be EQUAL TO -1/12 ???…

Riemann Zeta-function
Riemann zeta-function, a function useful in number theory for investigating properties of prime numbers. Written as ζ(x), it was originally defined as the infinite series That is, ζ(x) = 1 + 2−x + 3−x + 4−x + ⋯. When x = 1, this series is called the harmonic series, which increases without bound—i.e., its sum…

Euler’s Identity: A Mathematical Beauty
In mathematics, Euler’s identity (also known as Euler’s equation) is the equality. Euler’s identity is named after the Swiss mathematician Leonhard Euler. It is a special case of Euler’s formula when evaluated for x = π. where, e is Euler’s number, the base of natural logarithms, i is the imaginary unit, which by definition satisfies i2 = −1, and π is pi, the ratio of the circumference of a circle to its diameter. Mathematical beauty eh?! Euler’s identity is often cited…

How best to fill a circle with different shapes?!
I was wondering how can I fill a circle with a square. But, are you wondering, why am I bothered with this? Well, do you know the three “classical problems” in geometry??? The “classical problems” are Doubling the cube (i.e., constructing a cube whose volume is twice that of a given cube) Trisecting the angle, and …
