“It seemed, indeed, that the study of light-scattering might carry one into the deepest problems of physics and chemistry.”

It is generally believed that it is the students who derive benefit by working under the guidance of a professor.

When we consider the fact that nearly three-quarters of the surface of the globe is covered by oceanic water.

When I got my Nobel Prize, I had spent hardly 200 rupees on my equipment.

In reality, the professor benefits equally by his association with gifted students working under him.

From Calcutta has gone forth a living stream of knowledge in many branches of study. It is inspiring to think of the long succession of scholars, both Indian and European, who have lived in this city, made it their own, and given it of their best.

The sunlit face of the earth would appear to shine by the light diffused back into space from the land and water-covered areas.

I feel it is unnatural and immoral to try to teach science to children in a foreign language They will know facts, but they will miss the spirit.

It is not often that idealism of student days finds adequate opportunity for expression in the later life of manhood.

It will soon be 25 years from the date of publication of my first research work. That the scientific aspirations kindled by that early work did not suffer extinction has been due entirely to the opportunities provided for me by the great city of Calcutta.

It has been invariably my experience that I could count on his cooperation and sympathy in every matter concerning my scientific work.

We need a spirit of victory, a spirit that will carry us to our rightful place under the sun, a spirit which can recognize that we, as inheritors of a proud civilization, are entitled to our rightful place on this planet. If that indomitable spirit were to arise, nothing can hold us from achieving our rightful destiny.

We have, I think, developed an inferiority complex.

The essence of science is independent thinking, hard work, and not equipment.

It will not be an activity in which all people can participate.

A voyage to Europe in the summer of 1921 gave me the first opportunity of observing the wonderful blue opalescence of the Mediterranean Sea.

I strongly believe that fundamental science cannot be driven by instructional, industrial, governmental or military pressures.

The whole art of making experiments in chemistry is founded on the principle: we must always suppose an exact equality or equation between the principles of the body examined and those of the products of its analysis.

Perhaps; some day the precision of the data will be brought so far that the mathematician will be able to calculate at his desk the outcome of any chemical combination, in the same way, so to speak, as he calculates the motions of celestial bodies.

Well, I see I am not designed to the finding out the Philosophers Stone, I have been so unlucky in my first attempts in chemistry.

Sulfur, when burning, absorbs oxygen gas; the resulting acid is considerably heavier than the sulfur burned; its weight is equal to the sum of weights of the sulfur burned and the oxygen absorbed.

Deep breathing changes the chemistry of the body by bringing oxygen into the tissue.

Every season, really, has their own chemistry.

What I Thought was love, was really just lust-electrical chemistry, no emotional availability.

I’m reading so much and exposing myself to so many new ideas. It almost feels like the chemistry and the structure of my brain is changing so rapidly sometimes.
