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..
