Il futuro elettrico di Nikola Tesla

Torri radio sparse in tutto il mondo, raggi mortali, oscillatori sismici, comandi a distanza, energia verde. Ecco alcune delle invenzioni di una mente fertile che ha partecipato all'elettrificazione del mondo: Nikola Tesla. In America è considerato un eroe, uno degli inventori più importanti della Storia; la sua mente era in anticipo rispetto ai tempi. È lui ad aver trasformato la notte in giorno: è Nikola Tesla.

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, 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."  —

    "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)

    "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."  —

    "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."  —

    "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."  —

    "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."  —

    "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."  —

    "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."  —

    "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."  —

    "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."  —

    "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."  —

    "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."  —

    "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

    "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."  —

    "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."  —

    "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."  —

    "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."  —
