5 Good Books To Read On the History of Mathematics

Mathematics, like other forms of art and intellect, has had a long history, since the first numerical writing in years’ past. Although math has a long track record over time, its history is not taught enough (or not taught at at) in today’s schools. School children, nowadays, don’t

Equilateral Triangle

An Equilateral Triangle Inside a Square

This is an article on an olympiad problem. Here we present various solutions of the problem. We show the beauty of this problem by presenting different proofs to the same problem. The Problem Statement: – is a square. is a point inside the square such that . Show that is equilateral. A

1) A triangle has sides 13, 20, 21. Is there an altitude having integral length? 2) What is the minimum number of years needed for the total number of months in them is a number containing only the digits 0 and 1? 3) Suppose a, b are integers such that

Geometry Beyond Euclid

Geometry Beyond Euclid

We are very pleased to share a presentation made by Prof. M. S. Narasimhan at a KVPY Camp sometime back. The presentation entitled, ‘Geometry beyond Euclid’ was made on 19th October. This has been shared with us by our Advisory Board member Prof. Sujatha. The pdf file can be found

Hilbert's Axioms of Geometry

Hilbert's Axioms of Geometry

David Hilbert was a German mathematician who is known for his problem set that he proposed in one of the first ICMs, that have kept mathematicians busy for the last century. Hilbert is also known for his axiomatization of the Euclidean geometry with his set of 20 axioms. These axioms

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
