Jagadish Chandra Bose Quotes

The true laboratory is the mind, where behind illusions we uncover the laws of truth.

They would be our worst enemy who would wish us to live only on the glories of the past and die off from the face of the earth in sheer passivity. By continuous achievement alone we can justify our great ancestry. We do not honour our ancestors by the false claim that they are omniscient and had nothing more to learn.

The poet is intimate with truth, while the scientist approaches awkwardly. Come someday to my laboratory and see the unequivocable testimony of the crescograph.

Not in matter but in thought, not in possessions nor even in attainments but in ideals, is to be found the seed of immortality. Not through material acquisition but in generous diffusion of ideas and ideals can the true empire of humanity be established. Thus to Asoka, to whom belonged this vast empire, bound by the inviolate seas, after he had tried to ransom the world by giving away to the utmost, there came a time when he had nothing more to give, except one half of an Amlaki fruit. This was his last possession, and his anguished cry was that since he had nothing more to give, let the half of the Amlaki be accepted as his final gift.

[Science] was a human heritage] belonging neither to the East or the West.

To bringing about the scientific renaissance (In India) Sir Jagadish had influentially contributed. Indians are justly proud of the possession of a few men who have gained world-wide reputation in their particular fields of activity, and this pride reacts strongly on public opinion. At the Research Institute a group Indian post-graduate students devote their lives to research. The published Transactions of the Institute show that under the leadership of this eminent Bengali, Indian research is making substantial contribution to scientific knowledge, that in this field there is no fundamental difference between the Western and the Eastern mind, as was assumed when Sir Jagadish began his work.

Ashoka’s emblem of the Amlaki will be seen on the cornices of the Institute, and towering above all is the symbol of thunderbolt. It was the RishiDadhichi, the pure and blameless, who offered his life that the divine weapon, the thunderbolt, might be fashioned out of his bones to smite evil and exalt righteousness. It is but half of the Amlaki that we can offer now. But the past shall be reborn in a yet nobler future. We stand here today and resume work tomorrow, so that by the efforts of our lives and our unshaken faith in the future we may all help to build the greater India yet to be.

Our investigative research into the origin and first major use of solid state diode detector devices led to the discovery that the first transatlantic wireless signal in Marconi’s world-famous experiment was received by Marconi using the iron-mercury-iron-coherer with a telephone detector invented by Sir J.C. Bose in 1898.

He (Bose) was modern India’s first physicist after all, one of her very first scientists. He was his motherland’s first active participant in the Galilean - Newtonian tradition. He had confounded the British disbeliever. He had shown that the Eastern mind was indeed capable of the exact and exacting thinking demanded by western science. He had broken the mould.

The unique throb of life in all creation could seem only poetic imagery before your advent, Professor! A saint I once knew would never pluck flowers. 'Shall I rob the rosebush of its pride in beauty? Shall I cruelly affront its dignity by my rude divestment?' His sympathetic words are verified literally through your discoveries!"

I have recently returned from an expedition to scientific societies of the West. Their members exhibited intense interest in delicate instruments of my invention which demonstrate the indivisible unity of all life. The Bose crescograph has the enormity of ten million magnifications. The microscope enlarges only a few thousand times; yet it brought vital impetus to biological science. The crescograph opens incalculable vistas.

Sir J.C. Bose's pioneering works in quasi-optic millimeter wave research in Calcutta, India about 100 years back during 1890s are highlighted. He developed an elegant millimeter wave spark transmitter, self recovering coherer detector, wire grid polariser, cylindrical diffraction grating, dielectric lens and prism, rectangular waveguide, horn antenna and microwave absorber, for the studies of reflection, refraction, absorption and polarisation of millimeter waves and its application to wireless remote control for firing a gun. All these pioneering activities indicate that he was well ahead of his time and prompted us to call him the "Father of Radio Science".

...the "Resonant Cardiograph," Bose then pursued extensive researches on innumerable Indian plants. An enormous unsuspected pharmacopoeia of useful drugs was revealed. The cardiograph is constructed with an unerring accuracy by which a one-hundredth part of a second is indicated on a graph. Resonant records measure infinitesimal pulsations in plant, animal and human structure. The great botanist predicted that use of his cardiograph will lead to vivisection on plants instead of animals.

His model of an electric eye which records with electric signals message received from outside world, his physical model of memory as a mechanism for storing information justified this being considered a precursor of the modern discipline of cybernetics.

The generally accepted interpretation of Jagadish Chandra’s scientific activities is that he had essentially the biologist’s conception of Nature; lack of opportunities for biological studies while as a student in Calcutta and later lack of any teaching post in biology, induced Jagadish Chandra to take up the post of teacher in physics.
