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.

The Sensations of Tone.’ As is well known, this was one of Helmholtz’s masterpieces.

Is there any more encouraging sign than to see an Indian, who has never been to a university, like our friend Mr. Asutosh Dey here, for example, carrying out original work and finding it recognized by the foremost societies of the world?

We begin to realise that the molecular scattering of light in liquids may possess an astronomical significance, in fact contribute in an important degree to the observed albedo of the earth.

We are going to need the capacity to take a courageous stand when and where necessary.

I feel that it is our moral obligation to stand and to be courageous with these families, and particularly Cindy, that have become the conscience of this nation.

I was a photographer first.I worked alone. I did it my way as much as I could. I have been sort of courageous about doing things, because I didn’t think I should do less than my brothers.
