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

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 fundamental importance of the subject of molecular diffraction came first to be recognized through the theoretical work of the late Lord Rayleigh on the blue light of the sky, which he showed to be the result of the scattering of sunlight by the gases of the atmosphere.

It seemed not unlikely that the phenomenon owed its origin to the scattering of sunlight by the molecules of the water.

The whole edifice of modern physics is built up on the fundamental hypothesis of the atomic or molecular constitution of matter.

I have always thought it a great privilege to have as my colleague in the Palit Chair of Chemistry such a distinguished pioneer in scientific research and education in Bengal as Sir Prafulla Ray.

We must teach science in the mother tongue. Otherwise, science will become a highbrow activity.

Towards the end of February 1928, I took the decision of using brilliant monochromatic illumination obtained by the aid of the commercially available mercury arcs sealed in quartz tubes.

A revolution in consciousness is an empty high without a revolution in the distribution of power. We are not interested in the greening of Amerika except for the grass that will cover its grave.

If my face was covered, I would be useless.

Our whole childhood remains to be reimagined. In reimagining it, we have the possibility of recovering it in the very life of our reveries as a solitary child.

I jump out of planes, I could be covered in cockroaches, I do all sorts of things, but I just don’t like the feel of butterflies’ bodies.

When Mrs. Jinnah feels cold, she will say so, and ask for a wrap herself.

The boor covers himself, the rich man or the fool adorns himself, and the elegant man gets dressed.

My whole outlook on life is, never judge a book by its cover.

I sometimes wonder if two thirds of the globe is covered in red carpet.
