Frasi di Nikola Tesla

Nikola Tesla è stato un ingegnere elettrico, inventore e fisico serbo naturalizzato statunitense nel 1891.



È conosciuto per il suo lavoro rivoluzionario e i numerosi contributi nel campo dell'elettromagnetismo tra la fine dell'Ottocento e gli inizi del Novecento. I suoi numerosi brevetti e il suo lavoro teorico formano la base del moderno sistema elettrico a corrente alternata , compresa la distribuzione elettrica polifase e i motori elettrici a corrente alternata, con i quali ha contribuito alla nascita della seconda rivoluzione industriale.

Negli Stati Uniti d'America Tesla fu tra gli scienziati e inventori più famosi, anche nella cultura popolare. Dopo la sua dimostrazione di comunicazione senza fili nel 1893, e dopo essere stato il vincitore della cosiddetta "guerra delle correnti" insieme a George Westinghouse contro Thomas Alva Edison, fu riconosciuto come uno dei più grandi ingegneri elettrici statunitensi. Molti dei suoi primi studi si rivelarono anticipatori della moderna ingegneria elettrica e diverse sue invenzioni rappresentarono importanti innovazioni tecnologiche.

Tesla ha contribuito allo sviluppo di diversi settori delle scienze applicate. I suoi ammiratori contemporanei arrivano al punto da definirlo "l'uomo che inventò il Ventesimo secolo" e "il santo patrono della moderna elettricità". La sua importanza fu anche riconosciuta nella Conférence Générale des Poids et Mesures del 1960, in cui fu intitolata a suo nome l'unità del Sistema Internazionale di misura dell'induzione magnetica .

Tra i riconoscimenti, fu nominato vicepresidente dell'associazione oggi chiamata IEEE e venne insignito della settima Medaglia Edison nel 1917 dalla stessa IEEE, massimo riconoscimento assegnatogli in vita. Tesla fu erroneamente annunciato come vincitore del Premio Nobel per la fisica 1915 in un articolo pubblicato sul New York Times insieme a Edison; comunque nessuno dei due vinse mai il Nobel: secondo alcuni autori, proprio a causa della mancata volontà di condividere il premio tra loro.

Non mancarono contestazioni riguardo ai brevetti di Tesla. La scoperta del campo magnetico rotante, per esempio, fu descritta in una nota presentata alla Reale Accademia delle Scienze il 18 marzo 1888, dallo scienziato italiano Galileo Ferraris, ma da parte di Tesla nacquero subito contestazioni sulla priorità di tale scoperta, che finì nelle aule giudiziarie, dove si stabilì che la paternità dell'invenzione spettava allo scienziato italiano. Nel 1943 invece una sentenza della Corte Suprema degli Stati Uniti d'America attribuì a Tesla la paternità di alcuni brevetti usati per la trasmissione di informazioni via etere, tramite onde radio, precedentemente attribuiti a Guglielmo Marconi.

A causa della sua personalità eccentrica e delle sue affermazioni talvolta apparentemente bizzarre e incredibili, negli ultimi anni della sua vita Tesla fu ostracizzato e considerato una sorta di "scienziato pazzo" pur attribuendogli talora curiose anticipazioni di sviluppi scientifici successivi. Molti dei suoi risultati sono stati usati, spesso polemicamente, per appoggiare diverse pseudoscienze, teorie sugli UFO e occultismo New Age. Ciò è dovuto al fatto che Tesla lasciò scarsa documentazione sui risultati ottenuti, e anche questa spesso sotto forma di appunti, non di lavori organizzati e comprensibili a tutti . Pertanto è stato relativamente facile attribuirgli le idee più strampalate, o la paternità di invenzioni mirabolanti non accettate dalla "scienza ufficiale".

L'ultimo brevetto di Tesla risale al 1928: negli ultimi anni della sua vita intervenne spesso su quotidiani quali il New York Times e l'Electrical Experimenter riguardo alle sue visionarie opinioni sulla tecnologia o in relazione alla guerra in corso in Europa. Morì nel 1943 nell'hotel dove viveva; al suo funerale a New York erano presenti oltre duemila persone, tra cui diversi premi Nobel.

Nikola Tesla Frasi e Citazioni

“La scienza non è nient'altro che una perversione se non ha come suo fine ultimo il miglioramento delle condizioni dell'umanità.”

citato in Massimo Teodorani, Tesla Lampo di Genio, Macro Edizioni, p. 13

“La trasmissione economica dell'energia senza fili è di importanza fondamentale per l'uomo. Gli permetterà infatti di dominare incontrastato sull'aria, sul mare e sui deserti. L'uomo sarà libero dalla necessità di estrarre minerali o petrolio, trasportare e bruciare combustibili, abolendo così molteplici cause di inquinamento. […] Il glorioso sole diventerà il nostro servo ubbidiente. Pace e armonia si diffonderanno sulla Terra.”

The economic transmission of power without wires is of all-surpassing importance to man. By its means he will gain complete mastery of the air, the sea and the desert. It will enable him to dispense with the necessity of mining, pumping, transporting and burning fuel, and so do away with innumerable causes of sinful waste. [...] It will make the living glorious sun his obedient, toiling slave. It will bring peace and harmony on earth.

Nikola Tesla: Frasi in inglese

“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.”

"Radio Power Will Revolutionize the World" in Modern Mechanics and Inventions (July 1934)
Contesto: The scientists from Franklin to Morse were clear thinkers and did not produce erroneous theories. 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.

“Ere many generations pass, our machinery will be driven by a power obtainable at any point of the universe.”

"Experiments With Alternate Currents Of High Potential And High Frequency" (February 1892)
Contesto: Ere many generations pass, our machinery will be driven by a power obtainable at any point of the universe. This idea is not novel. Men have been led to it long ago by instinct or reason; it has been expressed in many ways, and in many places, in the history of old and new. We find it in the delightful myth of Antaeus, who derives power from the earth; we find it among the subtle speculations of one of your splendid mathematicians and in many hints and statements of thinkers of the present time. Throughout space there is energy. Is this energy static or kinetic! If static our hopes are in vain; if kinetic — and this we know it is, for certain — then it is a mere question of time when men will succeed in attaching their machinery to the very wheelwork of nature.

“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.”

On patent controversies regarding the invention of Radio and other things, as quoted in "A Visit to Nikola Tesla" by Dragislav L. Petković in Politika (April 1927); as quoted in Tesla, Master of Lightning (1999) by Margaret Cheney, Robert Uth, and Jim Glenn, p. 73 ISBN 0760710058 </small> ; also in Tesla: Man Out of Time (2001) by Margaret Cheney, p. 230 <small> ISBN 0743215362

“Peace can only come as a natural consequence of universal enlightenment and merging of races, and we are still far from this blissful realization.”

Nikola Tesla libro My Inventions: The Autobiography of Nikola Tesla

A Means for Furthering Peace (1905)
Origine: My Inventions: The Autobiography of Nikola Tesla
Contesto: A state of human life vaguely defined by the term "Universal Peace," while a result of cumulative effort through centuries past, might come into existence quickly, not unlike a crystal suddenly forms in a solution which has been slowly prepared. But just as no effect can precede its cause, so this state can never be brought on by any pact between nations, however solemn. Experience is made before the law is formulated, both are related like cause and effect. So long as we are clearly conscious of the expectation, that peace is to result from such a parliamentary decision, so long have we a conclusive evidence that we are not fit for peace. Only then when we shall feel that such international meetings are mere formal procedures, unnecessary except in so far as they might serve to give definite expression to a common desire, will peace be assured.
To judge from current events we must be, as yet, very distant from that blissful goal. It is true that we are proceeding towards it rapidly. There are abundant signs of this progress everywhere. The race enmities and prejudices are decidedly waning.

“Our virtues and our failings are inseparable, like force and matter. When they separate, man is no more.”

" The Problem of Increasing Human Energy http://www.tfcbooks.com/tesla/1900-06-00.htm", Century Illustrated Magazine (June 1900)

“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.”

A Means for Furthering Peace (1905)
Contesto: It is not a dream, it is a simple feat of scientific electrical engineering, only expensive — blind, faint-hearted, doubting world!... Humanity is not yet sufficiently advanced to be willingly led by the discover's keen searching sense. But who knows? Perhaps it is better in this present world of ours that a revolutionary idea or invention instead of being helped and patted, be hampered and ill-treated in its adolescence — by want of means, by selfish interest, pedantry, stupidity and ignorance; that it be attacked and stifled; that it pass through bitter trials and tribulations, through the heartless strife of commercial existence. So do we get our light. So 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.

“Most persons are so absorbed in the contemplation of the outside world that they are wholly oblivious to what is passing on within themselves.”

Nikola Tesla libro My Inventions: The Autobiography of Nikola Tesla

My Inventions (1919)
Origine: My Inventions: The Autobiography of Nikola Tesla
Contesto: From childhood I was compelled to concentrate attention upon myself. This caused me much suffering, but to my present view, it was a blessing in disguise for it has taught me to appreciate the inestimable value of introspection in the preservation of life, as well as a means of achievement. The pressure of occupation and the incessant stream of impressions pouring into our consciousness through all the gateways of knowledge make modern existence hazardous in many ways. Most persons are so absorbed in the contemplation of the outside world that they are wholly oblivious to what is passing on within themselves. The premature death of millions is primarily traceable to this cause. Even among those who exercise care, it is a common mistake to avoid imaginary, and ignore the real dangers. And what is true of an individual also applies, more or less, to a people as a whole.

“So astounding are the facts in this connection, that it would seem as though the Creator, himself had electrically designed this planet…”

A Means for Furthering Peace (1905)
Contesto: Electric current, after passing into the earth travels to the diametrically opposite region of the same and rebounding from there, returns to its point of departure with virtually undiminished force. The outgoing and returning currents clash and form nodes and loops similar to those observable on a vibrating cord. To traverse the entire distance of about twenty-five thousand miles, equal to the circumference of the globe, the current requires a certain time interval, which I have approximately ascertained. In yielding this knowledge, nature has revealed one of its most precious secrets, of inestimable consequence to man. So astounding are the facts in this connection, that it would seem as though the Creator, himself, had electrically designed this planet just for the purpose of enabling us to achieve wonders which, before my discovery, could not have been conceived by the wildest imagination.

“My method is different. I do not rush into actual work. When I get an idea I start at once building it up in my imagination. I change the construction, make improvements, and operate the device entirely in my mind.”

Nikola Tesla libro My Inventions: The Autobiography of Nikola Tesla

My Inventions (1919)
Origine: My Inventions: The Autobiography of Nikola Tesla
Contesto: The moment one constructs a device to carry into practice a crude idea, he finds himself unavoidably engrossed with the details of the apparatus. As he goes on improving and reconstructing, his force of concentration diminishes and he loses sight of the great underlying principle.… I do not rush into actual work. When I get an idea, I start at once building it up in my imagination. I change the construction, make improvements and operate the device in my mind. It is absolutely immaterial to me whether I run my turbine in thought or test it in my shop. I even note if it is out of balance.

“The individual is ephemeral, races and nations come and pass away, but man remains.”

The Problem of Increasing Human Energy (1900)
Contesto: When we speak of man, we have a conception of humanity as a whole, and before applying scientific methods to the investigation of his movement we must accept this as a physical fact. But can anyone doubt to-day that all the millions of individuals and all the innumerable types and characters constitute an entity, a unit? 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. I cut myself in the finger, and it pains me: this finger is a part of me. I see a friend hurt, and it hurts me, too: my friend and I are one. And now I see stricken down an enemy, a lump of matter which, of all the lumps of matter in the universe, I care least for, and it still grieves me. Does this not prove that each of us is only part of a whole?
For ages this idea has been proclaimed in the consummately wise teachings of religion, probably not alone as a means of insuring peace and harmony among men, but as a deeply founded truth. The Buddhist expresses it in one way, the Christian in another, but both say the same: We are all one. Metaphysical proofs are, however, not the only ones which we are able to bring forth in support of this idea. Science, too, recognizes this connectedness of separate individuals, though not quite in the same sense as it admits that the suns, planets, and moons of a constellation are one body, and there can be no doubt that it will be experimentally confirmed in times to come, when our means and methods for investigating psychical and other states and phenomena shall have been brought to great perfection. Still more: this one human being lives on and on. The individual is ephemeral, races and nations come and pass away, but man remains. Therein lies the profound difference between the individual and the whole.
