View All## Sample chapters from BASIC PHYSICS: Principles and Concepts (Avijit Lahiri)

Here are two sample chapters from my upcoming book ‘Basic Physics: Principles and Concepts’. The full book is in the process of revision and will be published soon. It was earlier published under a different title (‘Basic Physics: A Comprehensive Survey’). More..

## Quantum Theory: Under the Limelight, and Away from it (in Bengali)

This article focuses on episodes in the history of physics relating to the possible role of hidden variables in quantum theory – episodes involving John von Neumann, Grete Hermann, David Bohm, and John S. Bell. The glare of limelight sometimes obscures developments unfolding away from it that later turn out to be significant…… More..

## Induction, Logic, Science, and Belief (in Bengali)

Science is not just ‘perception plus logic’, since extra-logical elements are inexorably present, and possibly play an important role, in all scientific inquiry, in which tacit learning and inductive inference are involved as essential mechanisms…..A more complete form of the … More..

## Logic in Mathematics and the Sciences

Logic is supposed to provide a secure foundation to mathematics.In mathematics, ‘everything is logical and certain’ – such, at least, is the common perception of what mathematics is. In fact, things are not so simple, and logical perfection (or ‘completeness’) … More..

## Read my Bengali article on Alan Turing

This is the centenary year of that towering intellect, a great mathematician and logician of all times, who was made to meet an unfortunate end. More..

## Read my bengali article on the problem of interpretation of quantum theory

The world-view acquired from the macroscopic world we live in may not be competent enough to properly pose, let alone resolve, the problems of interpretation of quantum theory; nevertheless, some kind of an understanding and interpretation of the exotic rules … More..
