"I feel that we in India are apt to believe that good scientific institutions can be established by Government decree or order. A scientific institution, be it a laboratory or an academy, has to be grown with great care like a tree. Its growth in terms of quality and achievement can only be accelerated to a very limited extent. This is a field in which a large number of mediocre or second rate workers cannot make up for a few outstanding ones, and the few outstanding ones always take at least 10-15 years to grow. Too many of our National Laboratories have been established by deciding upon the field in which it was desired to work and by drawing up an organisational chart on the pattern of some corresponding large laboratory abroad. It was then assumed naively, that the posts in the chart could be filled by advertisement, forgetting that workers of the appropriate and high level either do not exist in India, or can only be obtained at the cost of some other institution, which thus becomes weaker of it. Our Universities, weak as they always were, have been further weakened in this matter."

"There is at the moment in India no big school of research in the fundamental problems of physics, both theoretical and experimental. There are, however, scattered all over India competent workers who are not doing as good work as they would do if brought together in one place under proper direction. It is absolutely in the interest of India to have a vigorous school of research in fundamental physics, for such a school forms the spearhead of research not only in less advanced branches of physics but also in problems of immediate practical application in industry. If much of the applied research done in India today is disappointing or of very inferior quality it is entirely due to the absence of sufficient number of outstanding pure research workers who would set the standard of good research and act on the directing boards in an advisory capacity … Moreover, when nuclear energy has been successfully applied for power production in say a couple of decades from now, India will not have to look abroad for its experts but will find them ready at hand. I do not think that anyone acquainted with scientific development in other countries would deny the need in India for such a school as I propose. The subjects on which research and advanced teaching would be done would be theoretical physics, especially on fundamental problems and with special reference to cosmic rays and nuclear physics, and experimental research on cosmic rays. It is neither possible nor desirable to separate nuclear physics from cosmic rays since the two are closely connected theoretically."

"I seriously say to you that business or job as an engineer is not the thing for me. It is totally foreign to my nature and radically opposed to my temperament and opinions. Physics is my line. I know I shall do great things here. For, each man can do best and excel in only that thing of which he is passionately fond, in which he believes, as I do, that he has the ability to do it, that he is in fact born and destined to do it... I am burning with a desire to do physics. I will and must do it sometime. It is my only ambition. I have no desire to be a "successful" man or the head of a big firm. There are intelligent people who like that and let them do it. … It is no use saying to Beethoven "You must be a scientist bybye for it is great thing" when he did not care two hoots for science; or to Socrates "Be an engineer; it is work of intelligent man." It is not in the nature of things. I therefore earnestly implore you to let me do physics."

"I know quite clearly what I want out of my life. Life and my emotions are the only things I am conscious of. I love the consciousness of life and I want as much of it as I can get. But the span of one's life is limited. What comes after death no one knows. Nor do I care. Since, therefore, I cannot increase the content of life by increasing its duration, I will increase it by increasing its intensity. Art, music, poetry and everything else … I do have this one purpose — increasing the intensity of my consciousness of life."

"This elegant generalization is mathematically very appealing; but physics means facing facts. You should take up case by case."

"One thing leads to another, and soon you are searching for answers to basic questions.Another time during lectures on Classical Logic, we were introduced to an “experimentum crucis”. It was illustrated by the deciding experiment of Fizeau on the speed of light in water as compared to its speed in air. Since wave theory predicts that speed in water is less, and corpuscular theory (with point particles) predicts it would be faster, this is supposed to have selected the wave theory is correct. But then how would one accommodate the photoelectric effect? Then it turns out that if the “corpuscle” of light had a finite size, corpuscular theory also predicts lower speed of light in water. But then one can ask how come photoelectric emission being prompt even in feeble light, how could the energy of a photon spread over π(λ/2)2 act as a whole and liberate a single photoelectron! This leads us to question the square of the amplitude being interpreted as the probability of the particle being formed in the immediate vicinity. How do probabilities enter quantum mechanics? Thus the questions (and the quest) go on."

"Ideas are like bundles of trajectories undergoing complicated evolution."

"While we have footprints on the sands of time, there is no trace of things yet to come."

"Religions are like lofty peaks rising high above the surrounding plains of our physical being, merging, as it were, into the distant domain of heaven itself, beckoning the human spirit with grandeur."

"We are creatures, not only of the mind, but of feelings and emotions as well. Indeed, feelings and emotions are more fundamental to our being than pure logic and reasoning."

"The fact is, when we are born, we are neither theists nor atheists, but ignoro-theists."

"What debaters in ivory towers often fail to realize is that when it comes to achieving well-defined goals, both theism and atheism can work."

"When one is involved in the discovery and discernment of the marvelous law and symmetries that shape the phenomenal world, one cannot but be struck by the silent and unfathomable intelligence that seems to pervade the Cosmos."

"condemning religions as a whole would be like wanting to destroy a garden because weeds have disfigured it."

"the technical work of scientists is blind to nationalities, they overlap and mingle like sounds from different instruments in an orchestra to create and constitute the grand symphony that science is."

"science and religion are intrinsically interconnected both being expressions of the human spirit."

"Bookish academics need to remember that when it comes to analyzing works regarded as sacred by vast numbers of people, sound scholarship is like the firmness of bones, while appreciation and sensitivity are like flesh and blood. Without the latter, the former is merely an ugly skeleton: morbid and monstrous, lifeless and lamentable. With the latter, scholarship becomes robust and living."

"From its earliest days, science has been embedded in society, there has been a continuous learning process in society as a whole, based on day to day experiences and this can become the body of the knowledge from which applications and understanding have grown. … Everything on earth has to function in harmony as a system, and it is only in such a system that humanity can flourish."
