This blog will become functional in a few days now (more or less!).
Meanwhile, friends and colleagues are requested to visit my current website. You will find my particulars there and a number of items that may be of interest to you. This site will give you an idea as to what type of posts you can expect in this blog when it gets going. Your opinions, of course, will be welcome.

I'll keep on adding posts at a leisurely pace.
This blog is entitled 'TacitKnowledge', recalling the work of the great scientist and philosopher Michael Polanyi. It is planned as a platform for much that we perceive but don't always share, fearing that our views are too vague to be of value.

Read my Bengali article on Philosophy of Mathematics

Starting from the work of Gottlob Frege and the success and failure of the logicist trend in the philosophy of mathematics, and then having a brief look at Zermelo-Frenkel set theory, I address a few basic issues in Mathematical Realism, also termed Platonism in mathematics. While prominent names in mathematics are known to have adopted the Platonist position, the latter is not free of problems of interpretation rooted deeply in our view of what mathematical truth is all about. I then counterpose the intuitionist view of mathematics against the Platonist view and briefly outline David Hilbert's project of looking for the consistency of Mathematics, aiming to reconcile the finitary approach with the Platonist point of view. This also engendered the possibility of a resolution between the realist and the intuitionist points of view, but that possibility was thwarted to a considerable extent by Goedel's incompleteness theorems. This leads to the position that different trends in …

my Bengali article on the somersaulting cat: বিড়ালের ডিগবাজি

The cat has, over decades, generated fabulous interest and attention in science and literature. The way it somersaults in air remained an enigma to physicists, till a series of investigations - some not quite friendly to the cat - has thrown light on the puzzle, and the basic principles underlying the somersault are now known. The somersault needs quite sophisticated analysis to be explained in reasonably clear terms. This raises a deep question.....

Inference Belief and Interpretation in Science

This monograph of mine inquires into the deeply cognitive roots of human scientific quest. The process of  making scientific inferences is continuous with the day-to-day inferential activity of individuals, and is predominantly inductive in nature.Inductive inference, which is fallible, exploratory, and open-ended,  is of essential relevance in our incessant efforts at making sense of a complex and uncertain world around us, and covers a vast range of cognitive activities, among which scientific exploration constitutes the pinnacle. Inductive inference has a personal aspect to it, being rooted in the cognitive unconscious of individuals, which has recently been found to be of paramount importance in a wide range of complex cognitive processes. One other major aspect of the process of inference making, including the making of scientific inferences, is the role of a vast web of beliefs lodged in the human mind, as also of a huge repertoir…
