Frasi celebri
90
4 Stars"It is true that some of them have had to do with wireless telegraphy and that in addition to the tower and poles there is a hole dug in the ground. This is 150 feet deep and is used in these experiments. The people about there, had they been awake instead of asleep, at other times would have seen even stranger things. Some day, but not at this time, I shall make an announcement of something that I never once dreamed of." — “Tesla's Flashes Startling” (New York Sun, 17 luglio 1903)

4 Stars"It is a simple feat of scientific electrical engineering — only expensive — blind, faint-hearted, doubting world." — “The Transmission of Electrical Energy Without Wires As a Means for Furthering Peace” (Electrical World & Engineer, 7 gennaio 1905)
88
4 Stars"With a different form of wireless instrument devised by me some years ago it was found practicable to locate a body of metallic ore below the ground, and it seems that a submarine could be similarly detected." — “Nikola Tesla Tells of Country's War Problems” (New York Herald, 15 aprile 1917)
87
5 Stars"We build but to tear down. Most of our work and resource is squandered. Our onward march is marked by devastation. Everywhere there is an appalling loss of time, effort and life. A cheerless view, but true." — “What Science May Achieve This Year” (Denver Rocky Mountain News, 16 gennaio 1910)
86
4 Stars"Most certainly, some planets are not inhabited, but others are, and among these there must exist life under all conditions and phases of development." — “How To Signal To Mars” (New York Times, 23 maggio 1909)
85
4 Stars"There is no conflict between the ideal of religion and the ideal of science, but science is opposed to theological dogmas because science is founded on fact. To me, the universe is simply a great machine which never came into being and never will end. The human being is no exception to the natural order. Man, like the universe, is a machine. Nothing enters our minds or determines our actions which is not directly or indirectly a response to stimuli beating upon our sense organs from without." — “A Machine to End War” (Liberty, febbraio 1935)
84
4 Stars"If this does not appeal to you sufficiently to recognize in me a discoverer of principles, do me, at least, the justice of calling me an "inventor of some beautiful pieces of electrical apparatus." — “Can Bridge the Gap to Mars” (New York Times, 23 giugno 1907)
83
4 Stars"If the genius of invention were to reveal to-morrow the secret of immortality, of eternal beauty and youth, for which all humanity is aching, the same inexorable agents which prevent a mass from changing suddenly its velocity would likewise resist the force of the new knowledge until time gradually modifies human thought." — “Mr. Tesla on the Wireless Transmission of Power” (New York World, 19 maggio 1907)
82
4 Stars"It is probable that we shall perfect instruments for indicating the altitude of a place by means of a circuit, properly constructed and arranged, and I have thought of a number of other uses to which this principle may be put." — “Tesla's New Discovery” (New York Sun, 30 gennaio 1901)
81
5 Stars"The future will show whether my foresight is as accurate now as it has proved heretofore." — “Famous Scientific Illusions” (Electrical Experimenter, febbraio 1919)
80
5 Stars"…the papers, which thirty years ago conferred upon me the honor of American citizenship, are always kept in a safe, while my orders, diplomas, degrees, gold medals and other distinctions are packed away in old trunks." — “My Inventions V – The Magnifying Transmitter” (Electrical Experimenter, giugno 1919)

So great has been the drain on them of late years that the specter of exhaustion is looming up threateningly in the distance…" — “Our Future Motive Power” (Everyday Science & Mechanics, dicembre 1931)
76
3 Stars"Technical invention is akin to architecture and the experts must in time come to the same conclusions I have reached long ago. Sooner or later my power system will have to be adopted in its entirety and so far as I am concerned it is as good as done." — “World System of Wireless Transmission of Energy” (Telegraph & Telegraph Age, 16 ottobre 1927)
75
3 Stars"If I were ever assailed by doubt of ultimate success I would dismiss it by remembering the words of that great philosopher, Lord Kelvin, who after witnessing some of my experiments said to me with tears in his eyes: 'I am sure you will do it." — “World System of Wireless Transmission of Energy” (Telegraph & Telegraph Age, 16 ottobre 1927)
74

71
3 Stars"…the idea gradually took hold of me that the earth might be used in place of the wire, thus dispensing with artificial conductors altogether. The immensity of the globe seemed an unsurmountable obstacle but after a prolonged study of the subject I became satisfied that the undertaking was rational…" — “Famous Scientific Illusions” (Electrical Experimenter, febbraio 1919)
70
4 Stars"That is the trouble with many inventors; they lack patience. They lack the willingness to work a thing out slowly and clearly and sharply in their mind, so that they can actually 'feel it work.' They want to try their first idea right off; and the result is they use up lots of money and lots of good material, only to find eventually that they are working in the wrong direction. We all make mistakes, and it is better to make them before we begin." — “Tesla, Man and Inventor” (New York Times, 31 marzo 1895)
69
3 Stars"No desire for material advantages has animated me in all this work, though I hope, for the sake of the continuance of my labors, that these will soon follow, naturally, as a compensation for valuable services rendered to science and industry." — “Some Experiments in Tesla's Laboratory with Currents of High Potential and High Frequency” (The Electrical Review, 29 marzo 1899)

67
4 Stars"On more than one occasion you have offended me, but in my qualities both as Christian and philosopher I have always forgiven you and only pitied you for your errors." — “Tesla's Complaint to Electrical Engineer Editor w/ Response” (The Electrical Engineer, 24 novembre 1898)
66
3 Stars"…these scientific developments may even affect our morals and customs. Perhaps we shall shortly get so used to this state of things that nobody will feel the slightest embarrassment while he is conscious that his skeleton and other particulars are being scrutinized by indelicate observers." — “On Roentgen Radiations” (Electrical Review, 8 aprile 1896)
65
4 Stars"But I hope that it will also be demonstrated soon that in my experiments in the West I was not merely beholding a vision, but had caught sight of a great and profound truth." — “Talking with the Planets” (Collier's Weekly, 9 febbraio 1901)
64
4 Stars"What the result of these investigations will be the future will tell; but whatever they may be, and to whatever this principle may lead, I shall be sufficiently recompensed if later it will be admitted that I have contributed a share, however small, to the advancement of science." — “The Tesla Alternate Current Motor” (The Electrical Engineer, 22 giugno 1888)
63
4 Stars"Our senses enable us to perceive only a minute portion of the outside world." — “The Transmission of Electrical Energy Without Wires As a Means for Furthering Peace” (Electrical World & Engineer, 7 gennaio 1905)
62
4 Stars"Like a flash of lightning and in an instant the truth was revealed. I drew with a stick on the sand the diagrams of my motor. A thousand secrets of nature which I might have stumbled upon accidentally I would have given for that one which I had wrestled from her against all odds and at the peril of my existence." —
61
4 Stars"The practical success of an idea, irrespective of its inherent merit, is dependent on the attitude of the contemporaries. If timely it is quickly adopted; if not, it is apt to fare like a sprout lured out of the ground by warm sunshine, only to be injured and retarded in its growth by the succeeding frost." —
60
4 Stars"Everyone should consider his body as a priceless gift from one whom he loves above all, a marvelous work of art, of indescribable beauty, and mystery beyond human conception, and so delicate that a word, a breath, a look, nay, a thought may injure it." — “The Problem of Increasing Human Energy” (The Century Magazine, giugno 1900)
59
4 Stars"Our virtues and our failings are inseparable, like force and matter. When they separate, man is no more." — “The Problem of Increasing Human Energy” (The Century Magazine, giugno 1900)
58
4 Stars"But the female mind has demonstrated a capacity for all the mental acquirements and achievements of men, and as generations ensue that capacity will be expanded; the average woman will be as well educated as the average man, and then better educated, for the dormant faculties of her brain will be stimulated to an activity that will be all the more intense and powerful because of centuries of repose. Woman will ignore precedent and startle civilization with their progress." —
57
4 Stars"The gift of mental power comes from God, Divine Being, and if we concentrate our minds on that truth, we become in tune with this great power. My Mother had taught me to seek all truth in the Bible." —
56
4 Stars"The spread of civilization may be likened to a fire; First, a feeble spark, next a flickering flame, then a mighty blaze, ever increasing in speed and power." —
55
4 Stars"There is something within me that might be illusion as it is often case with young delighted people, but if I would be fortunate to achieve some of my ideals, it would be on the behalf of the whole of humanity. If those hopes would become fulfilled, the most exiting thought would be that it is a deed of a Serb." —
54
4 Stars"My ear barely caught signals coming in regular succession which could not have been produced on earth…" —
53
5 Stars"You may live to see man-made horrors beyond your comprehension." —
52
4 Stars"More than 35 years ago, I undertook the production of these phenomena (of lightning) and, in 1899 I actually succeeded, using a generator of 2,000 horsepower, in obtaining discharges of 18,000,000 volts carrying currents of 1,200 amperes, which were of such power as to be audible at a distance of 13 miles. I also learned how to produce such lightnings as occur in Nature, and mastered all the technical difficulties in this connection. But I found that even in the small and comparatively negligible trigger work called for the employment of thousands of horsepower; and this is the great obstacle now in the way of this supreme accomplishment." —
51
5 Stars"Out of this war, the greatest since the beginning of history, a new world must be born, a world that would justify the sacrifices offered by humanity. This new world must be a world in which there shall be no exploitation of the weak by the strong, of the good by the evil; where there will be no humiliation of the poor by the violence of the rich; where the products of intellect, science and art will serve society for the betterment and beautification of life, and not the individuals for achieving wealth. 7 his new world shall not be a world of the downtrodden and humiliated, but of free men and free nations, equal in dignity and respect for man." —
50
5 Stars"The mind is sharper and keener in seclusion and uninterrupted solitude. No big laboratory is needed in which to think. Originality thrives in seclusion free of outside influences beating upon us to cripple the creative mind. Be alone, that is the secret of invention; be alone, that is when ideas are born." —
49
3 Stars"…I finally succeeded in reaching electrical movements or rates of delivery of electrical energy not only approximating, but, as shown in many comparative tests and measurements, actually surpassing those of lightning discharges…" — Patent 787,412 - Art of Transmitting Electrical Energy through the Natural Mediums
48
5 Stars"…the greatest value of my invention will result from its effect upon warfare and armaments, for by reason of its certain and unlimited destructiveness it will tend to bring about and maintain permanent peace among nations." — Patent 613,809 - Method of and Apparatus for Controlling Mechanism of Moving Vehicles
47
4 Stars"…for if the potential be sufficiently high and if the terminals of the coils be maintained at the proper altitudes the action described will take place, and a current will be transmitted through the elevated air strata, which will encounter little and possibly even less resistance than if conveyed through a copper wire of a practicable size." — Patent 645,576 - System of Transmission of Electrical Energy
46
4 Stars"Though free to think and act, we are held together, like the stars in the firmament, with ties inseparable. These ties cannot be seen, but we can feel them." — “The Problem of Increasing Human Energy” (The Century Magazine, giugno 1900)
45
4 Stars"My conviction has grown so strong that I no longer look on this plan of energy or intelligence transmission as a mere theoretical possibility, but as a serious problem in electrical engineering, which must be carried out some day." —
44
4 Stars"If you only knew the magnificence of the 3, 6 and 9, then you would have the key to the universe." —
43
4 Stars"Our first endeavors are purely instinctive prompting of an imagination vivid and undisciplined. As we grow older reason asserts itself and we become more and more systematic and designing. But those early impulses, though not immediately productive, are of the greatest moment and may shape our very destinies. Indeed, I feel now that had I understood and cultivated instead of suppressing them, I would have added substantial value to my bequest to the world. But not until I had attained manhood did I realize that I was an inventor." —
42
5 Stars"I am credited with being one of the hardest workers and perhaps I am, if thought is the equivalent of labour, for I have devoted to it almost all of my waking hours. But if work is interpreted to be a definite performance in a specified time according to a rigid rule, then I may be the worst of idlers. Every effort under compulsion demands a sacrifice of life-energy. I never paid such a price. On the contrary, I have thrived on my thoughts." —
41
4 Stars"The last 29 days of the month are the hardest." —
40
4 Stars"When the great truth accidentally revealed and experimentally confirmed is fully recognized, that this planet, with all its appalling immensity, is to electric currents virtually no more than a small metal ball and that by this fact many possibilities, each baffling imagination and of incalculable consequence, are rendered absolutely sure of accomplishment; when the first plant is inaugurated and it is shown that a telegraphic message, almost as secret and non-interfereable as a thought, can be transmitted to any terrestrial distance, the sound of the human voice, with all its intonations and inflections, faithfully and instantly reproduced at any other point of the globe, the energy of a waterfall made available for supplying light, heat or motive power, anywhere — on sea, or land, or high in the air — humanity will be like an ant heap stirred up with a stick: See the excitement coming!" — “The Transmission of Electrical Energy Without Wires” (Electrical World & Engineer , 5 marzo 1904)
39
5 Stars"A single ray of light from a distant star falling upon the eye of a tyrant in bygone times, may have altered the course of his life, may have changed the destiny of nations, may have transformed the surface of the globe, so intricate, so inconceivably complex are the processes of nature." —
38
4 Stars"When wireless is perfectly applied the whole earth will be converted into a huge brain, which in fact it is, all things being particles of a real and rhythmic whole. We shall be able to communicate with one another instantly, irrespective of distance. Not only this, but through television and telephony we shall see and hear one another as perfectly as though we were face to face, despite intervening distances of thousands of miles; and the instruments through which we shall be able to do his will be amazingly simple compared with our present telephone. A man will be able to carry one in his vest pocket." —
37
3 Stars"…Furthermore, an inducement must be offered to those who are engaged in the industrial exploitation of natural sources of power, as waterfalls, by guaranteeing greater returns on the capital invested than they can secure by local development of the property…" — “The Problem of Increasing Human Energy” (The Century Magazine, giugno 1900)
36
5 Stars"…With these developments we have every reason to anticipate that in a time not very distant most telegraphic messages across the oceans will be transmitted without cables. For short distances we need a 'wireless' telephone, which requires no expert operators…" — “The Problem of Increasing Human Energy” (The Century Magazine, giugno 1900)
35
5 Stars"But we shall not satisfy ourselves simply with improving steam and explosive engines or inventing new batteries; we have something much better to work for, a greater task to fulfill. We have to evolve means for obtaining energy from stores which are forever inexhaustible, to perfect methods which do not imply consumption and waste of any material whatever." — “The Age of Electricity” (Cassier's Magazine, marzo 1897)
34
5 Stars"But among all these many departments of research, these many branches of industry, new and old, which are being rapidly expanded, there is one dominating all others in importance—one which is of the greatest significance for the comfort and welfare, not to say for the existence, of mankind, and that is the electrical transmission of power." — “The Age of Electricity” (Cassier's Magazine, marzo 1897)
33
4 Stars"It was the artist, too, who awakened that broad philanthropic spirit which, even in old ages, shone in the teachings of noble reformers and philosophers, that spirit which makes men in all departments and positions work not as much for any material benefit or compensation -- though reason may command this also -- but chiefly for the sake of success, for the pleasure there is in achieving it and for the good they might be able to do thereby to their fellow-men. Through his influence types of men are now pressing forward, impelled by a deep love for their study, men who are doing wonders in their respective branches, whose chief aim and enjoyment is the acquisition and spread of knowledge, men who look far above earthly things, whose banner is Excelsior! Gentlemen, let us honor the artist; let us thank him, let us drink his health!" —
32
4 Stars"…these features chiefly interest the scientific man, the thinker and reasoner. There is another feature which affords us still more satisfaction and enjoyment, and which is of still more universal interest, chiefly because of its bearing upon the welfare of mankind. Gentlemen, there is an influence which is getting strong and stronger day by day, which shows itself more and more in all departments of human activity, and influence most fruitful and beneficial—the influence of the artist. It was a happy day for the mass of humanity when the artist felt the desire of becoming a physician, an electrician, an engineer or mechanician or—whatnot—a mathematician or a financier; for it was he who wrought all these wonders and grandeur we are witnessing. It was he who abolished that small, pedantic, narrow-grooved school teaching which made of an aspiring student a galley-slave, and he who allowed freedom in the choice of subject of study according to one's pleasure and inclination, and so facilitated development." —
31
5 Stars"But such cables will not be constructed, for ere long intelligence—transmitted without wires—will throb through the earth like a pulse through a living organism. The wonder is that, with the present state of knowledge and the experiences gained, no attempt is being made to disturb the electrostatic or magnetic condition of the earth, and transmit, if nothing else, intelligence." —
30
5 Stars"Of all the frictional resistances, the one that most retards human movement is ignorance, what Buddha called 'the greatest evil in the world.' The friction which results from ignorance can be reduced only by the spread of knowledge and the unification of the heterogeneous elements of humanity. No effort could be better spent." — “The Problem of Increasing Human Energy” (The Century Magazine, giugno 1900)
29
4 Stars"The scientific man does not aim at an immediate result. He does not expect that his advanced ideas will be readily taken up. His work is like that of a planter -- for the future. His duty is to lay foundation of those who are to come and point the way." — “The Problem of Increasing Human Energy” (The Century Magazine, giugno 1900)
28
3 Stars"I have had but little time to devote to the fulfillment of a duty which, next to that of turning his best efforts to diligent inquiry in the fields he has chosen, is the most important to a scientific man; namely, that of giving an exact record of the results obtained…" — “Some Experiments in Tesla's Laboratory with Currents of High Potential and High Frequency” (The Electrical Review, 29 marzo 1899)
27
4 Stars"The greatest energy of movement will be obtained when synchronism is maintained between the pump impulses and the natural oscillations of the system." —
26
5 Stars"All that was great in the past was ridiculed, condemned, combated, suppressed - only to emerge all the more powerfully, all the more triumphantly from the struggle. Let the future tell the truth and evaluate each one according to his work and accomplishments. The present is theirs, the future, for which I really worked, is mine." —
25
4 Stars"We are whirling through endless space, with and inconceivable speed, all around everything is spinning, everything is moving, everywhere there is energy. There must be some way of availing ourselves of this energy more directly. Then, with the light obtained from the medium, with the power derived from it, with every form of energy obtained without effort, from the store forever inexhaustible, humanity will advance with giant strides. The mere contemplation of these magnificent possibilities expand our minds, strengthens our hopes and and fills our hearts with supreme delight." —
24
4 Stars"The progressive development of man is vitally dependent on invention. It is the most important product of his creative brain. Its ultimate purpose is the complete mastery of mind over the material world, the harnessing of the forces of nature to human needs. This is the difficult task of the inventor who is often misunderstood and unrewarded. But he finds ample compensation in the pleasing exercises of his powers and in the knowledge of being one of that exceptionally privileged class without whom the race would have long ago perished in the bitter struggle against pitiless elements. Speaking for myself, I have already had more than my full measure of this exquisite enjoyment; so much, that for many years my life was little short of continuous rapture." —
23
4 Stars"Up to the age of eight years, my character was weak and vacillating. I had neither courage or strength to form a firm resolve. My feelings came in waves and surges and vibrated unceasingly between extremes. My wishes were of consuming force and like the heads of the hydra, they multiplied. I was oppressed by thoughts of pain in life and death and religious fear. I was swayed by superstitious belief and lived in constant dread of the spirit of evil, of ghosts, and ogres and other unholy monsters of the dark. Then, all at once, there came a tremendous change which altered the course of my whole existence." —
22
4 Stars"I have hundreds of inventions which I could not take the patents of, on account of my misfortune." —
21
3 Stars"One cannot help looking at that little bulb of Crookes with a feeling akin to awe, when he considers all that it has done for scientific progress - first, the magnificent wonderful achievements of Roentgen. Possibly, it may still contain a grateful Asmodeus, who will be let out of his narrow prison cell by a lucky student. At times it has seemed to me as though I myself heard a whispering voice, and I have searched eagerly among my dusty bulbs and bottles. I fear my imagination has deceived me, but there they are still, my dusty bulbs, and I am still listening hopefully." —
20
4 Stars"So astounding are the facts in this connection, that it would seem as though the Creator, himself had electrically designed this planet…" — “The Transmission of Electrical Energy Without Wires As a Means for Furthering Peace” (Electrical World & Engineer, 7 gennaio 1905)
19
5 Stars"Before I put a sketch on paper, the whole idea is worked out mentally. In my mind I change the construction, make improvements, and even operate the device. Without ever having drawn a sketch I can give the measurements of all parts to workmen, and when completed all these parts will fit, just as certainly as though I had made the actual drawings. It is immaterial to me whether I run my machine in my mind or test it in my shop. The inventions I have conceived in this way have always worked. In thirty years there has not been a single exception. My first electric motor, the vacuum wireless light, my turbine engine and many other devices have all been developed in exactly this way." —
18
5 Stars"I do not think there is any thrill that can go through the human heart like that felt by the inventor as he sees some creation of the brain unfolding to success… Such emotions make a man forget food, sleep, friends, love, everything." —
17
4 Stars"My method is different. I do not rush into actual work. When I get a new idea, I start at once building it up in my imagination, and make improvements and operate the device in my mind. When I have gone so far as to embody everything in my invention, every possible improvement I can think of, and when I see no fault anywhere, I put into concrete form the final product of my brain." —
16
5 Stars"Today's scientists have substituted mathematics for experiments, and they wander off through equation after equation, and eventually build a structure which has no relation to reality." —
15
4 Stars"The scientists of today think deeply instead of clearly. One must be sane to think clearly, but one can think deeply and be quite insane." —
14
4 Stars"If Edison had a needle to find in a haystack, he would proceed at once with the diligence of the bee to examine straw after straw until he found the object of his search… I was a sorry witness of such doings, knowing that a little theory and calculation would have saved him ninety per cent of his labor." —
13
5 Stars"I have been feeding pigeons, thousands of them for years. But there was one, a beautiful bird, pure white with light grey tips on its wings; that one was different. It was a female. I had only to wish and call her and she would come flying to me. I loved that pigeon as a man loves a women, and she loved me. As long as I had her, there was a purpose to my life." —
12
5 Stars"I come from a very wiry and long-lived race. Some of my ancestors have been centenarians, and one of them lived 129 years. I am determined to keep up the record and please myself with prospects of great promise. Then again, nature has given me a vivid imagination…" —

5 Stars"I do not hesitate to state here for future reference and as a test of the accuracy of my scientific forecast that flying machines and ships propelled by electricity transmitted without wire will have ceased to be a wonder in ten years from now. I would say five were it not that there is such a thing as “inertia of human opinion” resisting revolutionary ideas." —

2 Stars"I have observed in the House of Morgan a largeness, nobility and firmness of character the like of which is very scarce indeed. I can only smile when I read the attempts to find something discreditable in the transactions of J.P. Morgan & Co. Not a hundred of such investigations will ever uncover anything which an unprejudiced judge would not consider honorable, fair, decent and in every way conforming to the high ideals and ethical standards of business. I would be willing to stake my life on it." —

5 Stars"Th[e] problem was rendered extremely difficult, owing to the immense dimensions of the planet… But by gradual and continuous improvements of a generator of electrical oscillations… I finally succeeded in reaching rates of delivery of electrical energy actually surpassing those of lightning discharges… By use of such a generator of stationary waves and receiving apparatus properly placed and adjusted in any other locality, however remote, it is practicable to transmit intelligible signals, or to control or actuate at will any one apparatus for many other important and valuable purposes." — Patent 787,412 - Art of Transmitting Electrical Energy through the Natural Mediums

4 Stars"If there are intelligent inhabitants of Mars or any other planet, it seems to me that we can do something to attract their attention… I have had this scheme under consideration for five or six years." —

5 Stars"How extraordinary was my life an incident may illustrate… [As a youth] I was fascinated by a description of Niagara Falls I had perused, and pictured in my imagination a big wheel run by the Falls. I told my uncle that I would go to America and carry out this scheme. Thirty years later I saw my ideas carried out at Niagara and marveled at the unfathomable mystery of the mind." —

5 Stars"The day when we shall know exactly what “electricity” is, will chronicle an event probably greater, more important than any other recorded in the history of the human race. The time will come when the comfort, the very existence, perhaps, of man will depend upon that wonderful agent." —

5 Stars"There were many days when [I] did not know where my next meal was coming from. But I was never afraid to work, I went where some men were digging a ditch… [and] said I wanted to work. The boss looked at my good clothes and white hands and laughed to the others… but he said, “All right. Spit on your hands. Get in the ditch.” And I worked harder than anybody. At the end of the day I had $2." —

4 Stars"It has cost me years of thought to arrive at certain results, by many believed to be unattainable, for which there are now numerous claimants, and the number of these is rapidly increasing, like that of the colonels in the South after the war." — “Tesla's New Alternating Motors” (The Electrical Engineer, 24 settembre 1890)

5 Stars"Now, I must tell you of a strange experience which bore fruit in my later life. We had a cold [snap] drier than even observed before. People walking in the snow left a luminous trail. [As I stroked] Mačak's back, [it became] a sheet of light and my hand produced a shower of sparks. My father remarked, this is nothing but electricity, the same thing you see on the trees in a storm. My mother seemed alarmed. Stop playing with the cat, she said, he might start a fire. I was thinking abstractly. Is nature a cat? If so, who strokes its back? It can only be God, I concluded.
I cannot exaggerate the effect of this marvelous sight on my childish imagination. Day after day I asked myself what is electricity and found no answer. Eighty years have gone by since and I still ask the same question, unable to answer it." —1
4 Stars"Hardly is there a nation which has met with a sadder fate than the Serbians. From the height of its splendor, when the empire embraced almost the entire northern part of the Balkan peninsula and a large portion of what is now Austria, the Serbian nation was plunged into abject slavery, after the fateful battle of 1389 at the Kosovo Polje, against the overwhelming Asian hordes. Europe can never repay the great debt it owes to the Serbians for checking, by the sacrifice of its own liberty, that barbarian influx." —
