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, … More..
Jagadish Chandra Bose was a rare personality in Indian science as also in world science. His mind-boggling talent, however, did not taste its due success and fulfillment owing to a combination of internal and external factors that resulted in his … More..
Inferences are rooted in the cognitive system of the individual and of groups of individuals (the scientific communities in the case of scientific inferences) while, at the same time, these are aimed at grasping relevant aspects of a mind-independent reality. More..
The received view of science is that it is impersonal, logical and objective. In fact, the conceptual world that science builds up for us, has its roots in extra-logical factors in our inferential process involving tacit cognition and inductive inference. The received view … More..
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..
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..
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..
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..
‘The Unreasonable Effectiveness of Mathematics in the Natural Sciences’ – this is the title of a widely cited paper by the Nobel winning Hungarian Physicist Eugene P. Wigner, where he famously expresses his sense of puzzled wonder….. Read More (PDF)
‘Shut up and calculate!’ – this phrase has acquired wide currency in and outside the quantum community, and is supposed to express the attitude of the typical working quantum physicist confronting people outside the community. More..
Lev Davidovich Landau (1908-1968) was one among the great adventurer physicists of the twentieth century – one of those few who can be said to have left an indelible mark on the course of…..Read More(PDF)
A personal commentary on the state of fundamental physics to-day, in the wake of the award of Nobel prize to Peter Higgs and Francois Englert. Our search for answers to fundamental questions is being subjugated to money and power of … More..
• On perceiving a state of anxiety and tension among the passengers, why did the captain of the ship order it to be sunk in the high seas? ▪ Since the ship was in motion while remaining on the sea … More..
Grete Hermann (1901-1984) was a many-faceted woman of great versatility, talent, and character. She is known for her criticism (1935) of John von Neumann’s widely acclaimed ‘no-hidden-variable’ proof (1932) that played a crucial role in establishing the credentials of quantum … More..
Kolmogorov, the great mathematician, is reputed to have had broad cultural interests and, at the same time, had a complex mind and personality. Perceived as being genial, broad-minded, and highly spirited, he seemed to possess unfathomed passions and prejudices as … More..
A. N. Kolmogorov (1903-87) was one of the great mathematicians of all times. Among other epoch making contributions, he pioneered the modern approach to probability theory and stochastic processes, made a great contribution to the formulation of intuitionistic logic, gave … More..
• Why was the proposal of office reform made by the executive overruled by his boss when they were descending in a lift? ▪ Because the executive’s arguments lost weight. • Why did the electrical wires snap as the chairman … More..
In the year 1968, the Russian physicist Victor Veselago wrote a visionary paper that eventually came to hold the key to revolutionize the field of optics and, in a sense, of electromagnetic theory itself. In a few pages of amazingly … More..
• Why is life on the moon likely to be a hilarious affair? ▪ Because the moon lacks in gravity. • Why is it that the people in our villages get so little of electricity? ▪ Because they belong to … More..
• Why did the forward-thinking director of the premier technology institute order the removal of the large portrait of George Simon Ohm, and its replacement with a life-size negative made from the original? ▪ Because he wanted to register recognition … More..
The formula for EMI (equated monthly instalment) relating to a home loan or a car loan is something that claims our attention these days. Suppose you take on loan an amount P0 (the principal) for a period of N months … More..
Albert Einstein, the great pioneer of modern physics, was awarded the Nobel prize for his explanation of the photoelectric effect in 1905. While recently writing a book on basic concepts in physics, I was struck by the fact that almost … More..
