Frases de Nikola Tesla

“De todas as coisas, o que eu mais gosto são os livros.”

“esteja sozinho, esse é o segredo da invenção; estar sozinho, é aí que nascem as idéias.”

“Eu não creio que exista algo mais emocionante para o coração humano do que a emoção sentida pelo inventor quando ele vê alguma criação da mente se tornando algo de sucesso. Essas emoções fazem o homem esquecer comida, sono, amigos, amor, tudo.”

“Adquiri a capacidade de administrar o sono, ficar adormecido e despertar no momento designado. Se eu faço algo que não entendo, me obrigo a pensar em meu sonho para encontrar assim uma solução. A quinta condição de ajuste é a memória. Talvez, na maioria das pessoas, o cérebro é o guardião dos conhecimentos sobre o mundo e o conhecimento adquirido através da vida. Meu cérebro está ocupado em coisas mais importantes que recordar, está recolhendo o que se requer em um momento dado, isto é, tudo o que nos rodeia. Só há que interiorizá-lo. Tudo o que vimos uma vez, escutamos, lemos e aprendemos, nos acompanha na forma de partículas de luz. Para mim, estas partículas são obedientes e fiéis.”

“O mundo não está preparado para isso. É algo muito além do nosso tempo, mas as leis vão prevalecer, e um dia farão um sucesso triunfante.”

“Marconi é um bom camarada. Deixe ele continuar seus trabalhos. Ele está usando dezessete de minhas patentes.”

“Nós almejamos por novas sensações, mas logo nos tornamos indiferentes à elas. As maravilhas de ontem são coisas comuns hoje em dia.”

“Cientistas de hoje substituíram a matemática por experiências, e eles afastam-se, equação depois de cada equação, e eventualmente constroem uma estrutura que não tem nenhuma relação com a realidade.”

“É certamente preferível produzir vegetais, e penso, por isso, que o vegetarianismo é um louvável abandono de um habito bárbaro instituído. Que podemos subsistir com alimentos vegetais e fazer o nosso trabalho até com vantagens não é uma teoria, mas sim um facto bem demonstrado. Muitas raças vivem quase exclusivamente á base de vegetais e são superiores psicologicamente e em força. (…) Tendo em conta estes factos, todos os esforços devem ser feitos para parar o abate cruel e desnecessários de animais, que deve ser destrutivo para os nossos princípios morais.”

“O que um homem chama de Deus, o outro chama de leis da física.”

“É preciso ser sensato para pensar com clareza, mas pode-se pensar profundamente e ser bastante insano.”

“It has been argued that the perfection of guns of great destructive power will stop warfare. So I myself thought for a long time, but now I believe this to be a profound mistake. Such developments will greatly modify, but not arrest it. On the contrary, I think that every new arm that is invented, every new departure that is made in this direction, merely invites new talent and skill, engages new effort, offers new incentive, and so only gives a fresh impetus to further development. Think of the discovery of gun-powder. Can we conceive of any more radical departure than was effected by this innovation? Let us imagine ourselves living in that period: would we not have thought then that warfare was at an end, when the armor of the knight became an object of ridicule, when bodily strength and skill, meaning so much before, became of comparatively little value? Yet gunpowder did not stop warfare: quite the opposite it acted as a most powerful incentive.”

“For every person who perishes from the effects of a stimulant, at least a thousand die from the consequences of drinking impure water. This precious fluid, which daily infuses new life into us, is likewise the chief vehicle through which disease and death enter our bodies. The germs of destruction it conveys are enemies all the more terrible as they perform their fatal work unperceived. They seal our doom while we live and enjoy. The majority of people are so ignorant or careless in drinking water, and the consequences of this are so disastrous, that a philanthropist can scarcely use his efforts better than by endeavoring to enlighten those who are thus injuring themselves. By systematic purification and sterilization of the drinking water the human mass would be very considerably increased. It should be made a rigid rule which might be enforced by law to boil or to sterilize otherwise the drinking water in every household and public place. The mere filtering does not afford sufficient security against infection. All ice for internal uses should be artificially prepared from water thoroughly sterilized. The importance of eliminating germs of disease from the city water is generally recognized, but little is being done to improve the existing conditions, as no satisfactory method of sterilizing great quantities of water has yet been brought forward. By improved electrical appliances we are now enabled to produce ozone cheaply and in large amounts, and this ideal disinfectant seems to offer a happy solution of the important question.”

“One afternoon, which is ever present in my recollection, I was enjoying a walk with my friend in the city park and reciting poetry. At that age I knew entire books by heart, word for word. One of these was Goethe's Faust. The sun was just setting and reminded me of a glorious passage:
Sie rückt und weicht, der Tag ist überlebt,
Dort eilt sie hin und fördert neues Leben.
O! daß kein Flügel mich vom Boden hebt,
Ihr nach und immer nach zu streben!
Ein schöner Traum, indessen sie entweicht.
Ach! zu des Geistes Flügeln wird so leicht
Kein körperlicher Flügel sich gesellen![The glow retreats, done is the day of toil;
It yonder hastes, new fields of life exploring;
Ah, that no wing can lift me from the soil
Upon its track to follow, follow soaring!
A glorious dream! though now the glories fade.
Alas! the wings that lift the mind no aid
Of wings to lift the body can bequeath me.
(tr. Bayard Taylor)
As I uttered these inspiring words the idea came like a flash of lightning and in an instant the truth was revealed. I drew with a stick on the sand the diagram shown six years later in my address before the American Institute of Electrical Engineers, and my companion understood them perfectly. The images I saw were wonderfully sharp and clear and had the solidity of metal and stone, so much so that I told him, "See my motor here; watch me reverse it."”

“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.”
