On the 14th January 1916, Dr. J. C. Bose delivered a public lecture, on Light Visible and Invisible, at the third Indian Science Congress held at Lucknow, before a crowded audience which included the Lieutenant-Governor (Sir James Meston).

Dr. Bose, in course of his lecture, spoke of the imperfection of our senses. Our ear, for example, fails to respond to all sounds. There are many sounds to which we are deaf. This was because our ear was tuned to answer to the narrow range of eleven octaves of sound vibrations. He showed a remarkable experiment of an artificial ear which remained irresponsive to various sounds, but when a particular note, to which it was tuned, was sounded even at the distant end of the hall, this ear picked it up and responded violently. As there were sounds audible and inaudible, so there were lights visible and invisible. The imperfection of our eye as a detector of ether vibrations was, however, far more serious. The eye could detect ether vibrations lying within a single octave--between 400 to 800 billion vibrations per second. Comparatively slow vibrations of ether did not affect our eye and the disturbances they give rise to well-known as electric waves. The electric waves, predicted by Maxwell, were discovered by Hertz. These waves were about three metres long. They were about ten million times larger than the beams of visible light. Dr. Bose showed that the three short electric waves have the same property as a beam of light, exhibiting reflections, refraction, even total reflection, through a black crystal, double refraction, polarisation, and rotation of the plane of polarisation. The thinnest film of air was sufficient to produce total reflection of visible light with its extremely short wave lengths. But with the new electric waves which he produced, Dr. Bose showed that the critical thickness of air s.p.a.ce determined by the refracting power of the prison and by the wave length of electric oscillations. Dr. Bose determined the index of refraction of electric waves for different materials, and eliminated a difficulty which presented itself in Maxwell's theory as to the relation between the index of refraction of light and the di-electric constant of insulators. He also measured the wave lengths of various oscillations. The order to produce short electric oscillations, to detect them and study their optical properties, he had to construct a large number of instruments. It was a hard task to produce very short electric waves which had enough energy to be detected, but Dr. Bose overcame this difficulty by constructing radiators or oscillators of his own type, which emitted the shortest waves with sufficient energy. As a receiver he used a sensitive metallic coherer, which in itself led to new and important discoveries. When electric waves fall on a loose contact between two pieces of metals, the resistance of the contact changes and a current pa.s.ses through the contact indicating the existence of electrical oscillations. Dr. Bose discovered the surprising fact that with pota.s.sium metal the resistance of the contact increases under the action of electric waves and that this contact exhibits an automatic recovery. He found further that the change of the metallic contact resistance when acted upon by electric waves, is a function of the atomic weight. These phenomena led to a new theory of metallic coherers. Before these discoveries it was a.s.sumed that the particles of the two metallic pieces in contact are, as it were, fused together, so that the resistance decreases. But the increasing resistance appearing for some elements, led to the theory that the electric forces in the waves produced a peculiar molecular action or a re-arrangement of the molecules, which may either increase or decrease the contact resistance.

HINDU UNIVERSITY ADDRESS

The foundation of the Hindu University was laid by Lord Hardinge on the 4th February 1916. "Many striking addresses were delivered on the occasion. Professor J.C. Bose in his masterly address went to the root of the matter and pointed in an inspiring manner what should be done to make the Hindu University worthy of its name. He deprecated a repet.i.tion of the Universities of the West." He said:--

In tracing the characteristic phenomenon of life from simple beginnings in that vast region which may be called unvoiced, as exemplified in the world of plants, to its highest expression in the animal kingdom, one is repeatedly struck by the one dominant fact that in order to maintain an organism at the height of its efficiency something more than a mechanical perfection of its structure is necessary. Every living organism, in order to maintain its life and growth, must be in free communion with all the forces of the Universe about it.

STIMULUS WITHIN AND WITHOUT

Further, it must not only constantly receive stimulus from without, but must also give out something from within, and the healthy life of the organism will depend on these two fold activities of inflow and outflow. When there is any interference with these activities, then morbid symptoms appear, which ultimately must end in disaster and death.

This is equally true of the intellectual life of a Nation. When through narrow conceit a Nation regards itself self-sufficient and cuts itself from the stimulus of the outside world, then intellectual decay must inevitably follow.

SPECIAL FUNCTION OF A NATION

So far as regards the receptive function. Then there is another function in the intellectual life of a Nation, that of spontaneous outflow, that giving out of its life by which the world is enriched. When the Nation has lost this power, when it merely receives, but cannot give out, then its healthy life is over, and it sinks into a degenerate existence which is purely parasitic.

HOW INDIA CAN TEACH

How can our Nation give out of the fulness of the life that is in it, and how can a new Indian University help in the realisation of this object? It is clear that its power of directing and inspiring will depend on its world status. This can be secured to it by no artificial means, nor by any strength in the past; and what is the weakness that has been paralysing her activities for the accomplishment of any great scientific work? There must be two different elements, and these must be evenly balanced. Any excess of either will injure it.

HOW TO SECURE THIS STATUS

This world status can only be won by the intrinsic value of the great contributions to be made by its own Indian scholars for the advancement of the world's knowledge. To be organic and vital our new University must stand primarily for self-expression, and for winning for India a place she has lost. Knowledge is never the exclusive possession of any particular race, nor does it recognise geographical limitations. The whole world is interdependent, and a constant stream of thought had been carried out throughout the ages enriching the common heritage of mankind. Although science was neither of the East nor of the West but international, certain aspects of it gained richness by reason of their place of origin.

In any case if India need to make any contribution to the world it should be as great as the hope they cherished for her. Let them not talk of the glories of the past till they have secured for her, her true place among the intellectual nations of the world. Let them find out how she had fallen from her high estate and ruthlessly put an end to all that self satisfied and little-minded vanity which had been the cause of their fatal weakness. What was it that stood in her way? Was her mind paralysed by weak superst.i.tious fears? That was not so; for her great thinkers, the Rishis, always stood for freedom of intellect and while Galileo was imprisoned and Bruno burnt for their opinions, they boldly declared that even the Vedas were to be rejected if they did not conform to truth. They urged in favour of persistent efforts for the discovery of physical causes yet unknown, since to them nothing was extra-physical but merely mysterious because of a hitherto unascertained cause. Were they afraid that the march of knowledge was dangerous to true faith? Not so. For their knowledge and religion were one.

These are the hopes that animate us. For there is something in the Hindu culture which is possessed of extraordinary latent strength by which it has resisted the ravages of time and the destructive changes which have swept over the earth. And indeed a capacity to endure through infinite transformations must be innate in that mighty civilisation which has seen the intellectual culture of the Nile Valley, of a.s.syria and of Babylon war and wane and disappear and which to-day gazes on the future with the same invincible faith with which it met the past.

THE HISTORY OF A FAILURE THAT WAS GREAT

At the invitation of the President and the committee of the Faridpore Industrial Exhibition, Dr. J. C. Bose gave a lecture on the life of his father, the late Babu Bhugwan Chunder Bose, who founded the Exhibition at Faridpore, where he was the sub-divisional officer, 50 years ago. It was published in the Modern Review for February 1917--volume xxi, p.

221. In course of his address, said Dr. Bose:--

It is the obvious, the insistent, the blatant that often blinds us to the essential. And in solving the mystery that underlies life, the enlightenment will come not by the study of the complex man, but through the simpler plant. It is the unsuspected forces, hidden to the eyes of men,--the forces imprisoned in the soil and the stimuli of alternating flash of light and the gloomings of darkness these and many others will be found to maintain the ceaseless activity which we know as the fulness of throbbing life.

This is likewise true of the congeries of life which we call a society or a nation. The energy which moves this great ma.s.s in ceaseless effort to realise some common aspiration, often has its origin in the unknown solitudes of a village life. And thus the history of some efforts, not forgotten, which emanated from Faridpore, may be found not unconnected with which India is now meeting her problems to-day. How did these problems first dawn in the minds of some men who forecast themselves by half a century? How fared their hopes, how did their dreams become buried in oblivion? Where lies the secret of that potency which makes certain efforts apparently doomed to failure, rise renewed from beneath the smouldering ashes? Are these dead failures, so utterly unrelated to some great success that we may acclaim to day? When we look deeper we shall find that this is not so, that as inevitable as in the sequence of cause and effect, so unrelenting must be the sequence of failure and success. We shall find that the failure must be the antecedent power to lie dormant for the long subsequent dynamic expression in what we call success. It is then and then only that we shall begin to question ourselves which is the greater of the two, a n.o.ble failure or a vulgar success.

As a concrete example, I shall relate the history of a n.o.ble failure which had its setting in this little corner of the earth. And if some of the audience thought that the speaker has been blessed with life that has been unusually fruitful, they will soon realise that the power and strength that nerved me to meet the shocks of life were in reality derived at this very place, where I witnessed the struggle which overpowered a far greater life.

STIMULUS OF CONTACT WITH WESTERN CULTURE

An impulse from outside reacts on impressionable bodies in two different ways, depending on whether the recipient is inert or fully alive. The inert is fashioned after the pattern of the impression made on it, and this in infinite repet.i.tion of one mechanical stamp. But when an organism is fully alive, the answering reaction is often of an altogether different character to the impinging stimulus. The outside shocks stir up the organism to answer feebly or to utmost in ways as mult.i.tudinous and varied as life itself. So the first impetus of Western education impressed itself on some in a dead monotony of imitation of things Western; while in others it awakened all that was greatest in the national memory. It is the release of some giant force which lay for long time dormant. My father was one of the earliest to receive the impetus characteristic of the modern epoch as derived from the West. And in his case it came to pa.s.s that the stimulus evoked the latent potentialities of his race for evolving modes of expression demanded by the period of transition in which he was placed. They found expression in great constructive work, in the restoration of quiet amidst disorder, in the earliest effort to spread education both among men and women, in questions of social welfare, in industrial efforts, in the establishment of people's Bank and in the foundation of industrial and technical schools. And behind all these efforts lay a burning love for his country and its n.o.bler traditions.

MATTERS EDUCATIONAL

In educational matters he had very definite ideas which is now becoming more fully appreciated. English schools were at that time not only regarded as the only efficient medium for instruction. While my father's subordinates sent their children to the English schools intended for gentle folks, I was sent to the vernacular school where my comrades were hardy sons of toilers and of others who, it is now the fashion to regard, were belonging to the depressed cla.s.ses. From these who tilled the ground and made the land blossom with green verdure and ripening corn, and the sons of the fisher folk, who told stories of the strange creatures that frequented the unknown depths of mighty rivers and stagnant pools, I first derived the lesson of that which const.i.tutes true manhood. From them too I drew my love of nature. When I came home accompanied by my comrades I found my mother waiting for us. She was an orthodox Hindu, yet the "untouchableness" of some of my school fellows did not produce any misgivings in her. She welcomed and fed all these as her own children; for it is only true of the mother heart to go out and enfold in her protecting care all those who needed succour and a mother's affection. I now realise the object of my being sent at the most plastic period of my life to the vernacular school, where I was to learn my own language, to think my own thoughts and to receive the heritage of our national culture through the medium of our own literature. I was thus to consider myself one with the people and never to place myself in an equivocal position of a.s.sumed superiority. This I realised more particularly when later I wished to go to Europe and to compete for the Indian Civil Service, his refusal as regards that particular career was absolute. I was to rule n.o.body but myself, I was to be a scholar not an administrator.

THE HISTORY OF A FAILURE THAT WAS GREAT

There has been some complaint that the experiment of meeting out cut and dried moral texts as a part of school routine has not proved to be so effective as was expected by their promulgators. The moral education which we received in our childhood was very indirect and came from listening to stories recited by the 'Kathas' on various incidents connected with our great epics. Their effect on our minds was very great; this may be because our racial memory makes us more p.r.o.ne to respond to certain ideals that have been impressed on the consciousness of the nation. These early appeals to our emotions have remained persistent; the only difference is that which was there as a narrative of incidents more or less historical, is now realised as eternally true, being an allegory of the unending struggle of the human soul in its choice between what is material and that other something which transcends it. The only pictures now in my study are a few frescoes done for me by Abanindra Nath Tagore and Nanda Lal Bose. The first fresco represents Her, who is the Sustainer of the Universe. She stands pedestalled on the lotus of our heart. The world was at peace; but a change has come. And She under whose Veil of Compa.s.sion we had been protected so long, suddenly flings us to the world of conflict. Our great epic, the Mahabharata, deals with this great conflict, and the few frescoes delineate some of the fundamental incidents. The coming of the discord is signalled by the rattle of dice, thrown by Yudhisthira, the p.a.w.n at stake, being the crown. Two hostile arrays are set in motion, mighty Kaurava armaments meeting in shock of battle the Pandava host with Arjuna as the leader, and Krishna as his Divine Charioteer. At the supreme moment Arjuna had flung down his earthly weapon, Gandiva. It was then that the eternal conflict between matter and spirit was decided.

The next panel shows the outward or the material aspect of victory.

Behind a foreground of waving flags is seen the battle field of Kurukshetra with procession of white-clad mourning women seen by fitful lights of funeral pyres. In the last panel is seen Yudhisthira renouncing the fruits of his victory setting out on his last journey. In front of him lies the vast and sombre plain and mountain peaks, faintly visible by gleams of unearthly light, unlocalised but playing here and there. His wife and his brothers had fallen behind and dropped one by one. There is to be no human companion in his last journey. The only thing that stood by him and from which he had never been really separated is Dharma or the Spirit of Righteousness.

LIFE OF ACTION

Faridpur at that time enjoyed a notoriety of being the stronghold of desperate characters, dacoits by land and water. My father had captured single-handed one of the princ.i.p.al leaders, whom he sentenced to a long term of imprisonment. After release he came to my father and demanded some occupation, since the particular vocation in which he had specialised was now rendered impossible. My father took the unusual course to employ him as my special attendant to carry me, a child of four, on his back to the distant village school. No nurse could be tenderer than this ex-leader of lawless men, whose profession had been to deal out wounds and deaths. He had accepted a life of peace but he could not altogether wipe out his old memories. He used to fill my infant mind with the stories of his bold adventures, the numerous fights in which he had taken part, the death of his companions and his hair-breadth escapes. Numerous were the decorations he bore. The most conspicuous was an ugly mark on his breast left by an arrow and a hole on the thigh caused by a spear thrust. The trust imposed on this marauder proved to be not altogether ill placed for once in a river journey we were pursued by several long boats filled with armed dacoits.

When these boats came too near for us to effect an escape the erstwhile dacoit leader, my attendant, stood up and gave a peculiar cry, which was evidently understood. For the pursuing boats vanished at the signal.

INDUSTRIAL EFFORTS

I come now to another period of his life fifty years from now, when he foresaw the economic danger that threatened his country. This Agricultural and Industrial Exhibition was one of the first means he thought of to avert the threatened danger. Here also he attempted to bring together other activities. Evening entertainments were given by the performances of "Jatras," which have been the expression of our national drama and which have constantly enriched our Bengali literature by the contributions of village bards and composers. There were athletic tournaments also and display of physical strength and endurance. He also established here the people's Bank, which is now in a most flourishing condition. He established industrial and technical schools, and it was there that the inventive bend of my mind received its first impetus. I remember the deep impression made on my mind by the form of worship rendered by the artisans to Viswakarma G.o.d in his aspect as the Great Artificer: His hand it was that was moulding the whole creation; and it seemed that we were the instruments in his hand, through whom he intended to fashion some Great Design.

In practical agriculture my father was among Indians one of the first to start a tea industry in a.s.sam, now regarded as one of the most flourishing. He gave practically everything in the starting of some Weaving Mills. He stood by this and many other efforts in industrial developments. The success of which I spoke did not come till long after--too late for him to see it. He had come before the country was ready, and it happened to him as it must happen to all pioneers. Every one of his efforts failed and the crash came. And a great burden fell on us which was only lifted by our united effects just before his work here was over.

A failure? Yes but not ign.o.ble or altogether futile. Since it was through the witnessing of this struggle that the son learned to look on success or failure as one, to realise that some defeat was greater than victory. And if my life in any way proved to be fruitful, then that came through the realisation of this lesson.

To me his life had been one of blessing and daily thanksgiving.

Nevertheless every one had said that he wrecked his life which was meant for far greater things. Few realise that out of the skeletons of myriad lives have been built vast continents. And it is on the wreck of a life like his and of many such lives there will be built the Greater India yet to be. We do not know why it should be so, but we do know that the Earth Mother is hungry for sacrifice.

QUEST OF TRUTH AND DUTY

Sir Jagadis Chandra Bose delivered the following Address, on the 25th February 1917, to the students of the Presidency College on receiving their _Arghya_ and congratulations on the occasion of his knighthood. It was published in the Modern Review for March 1917--Volume XXI, p. 343.
