This is the second proof among the six different proofs of the infinity of primes which appear in "Proofs from the Book". This proof is based on the use of Fermat's number.

This a small review of a marvellous book called " Proofs from the Book" by Aigner and Ziegler. This is a review of the 6th edition

This is a video essentially for high-school students and beginning undergraduate students. It tells you how to count the subsets of a finite set. This proves that the the total number of subsets of a set with n elements is two raised to the power n. In case you want the copy of the note send a mail to me at mathjoy.dutta@gmail.com

This video talks about a book called All the Math You Missed By Thomas Garrity

February 12th is usually celebrated world over as Darwin Day. In 1809 on this day the famous biologist, Charles Darwin, was born. It is a day to celebrate science. So in this channel in my own imperfect way I wanted to celebrate this day with you all.

This is a new year chit chat with my subscribers and other viewers. Here as a celebration of the link between mathematics and physics, we discuss a bit from the book "Pricincipia for the Common Reader by S. Chandrashekar. A correction : At around 4 minutes into the video I had mentioned about the Chadrashekar Limit. I said it is 1.44 times the mass of the earth. It is 1.44 times the mass of the...

In this video I introduce the four lovely books by Leonard Susskind on Classical mechanics, Quantum mechanics, Special relativity and classical filed theory and general relativity under four different volumes of a series called Theoretical minimum. This is a celebration of the deep connection between mathematics and physics.

This is small introduction to the Dover edition of the fabulous graph theory book by Narsingh Deo. Though an old book it still relevant book and very inspiring and remains one of my favourite math text.

In this video we shall discuss the Konigsberg bridge problem which led to the emergence of graph theory. This is the start of a few talks on graph theory. Hoping these will be useful. We will also discuss books on the subject.

In this video I talk about my recent visit to the UK and my visit to the Natural History Museum there and trying to record in front of the statue of Jame Clerk Maxwell and my amazing experience in knowing more about the life of Galileo. I also read the first part of the scene 1 of the famous drama of Bertolt Brecht called "Life of Galileo".

This video shows my new office at the Enginnering Science building at IIT Kanpur.

This is an afternoon in my office where I pick up some books randomly and discuss their contents of those books. Just trying to express the joy of engaging with mathematics

In this video we use the second law of Newton in a second order differential equation format and show the predictive power of the approach .
