I have never failed in any of my experiments and therefore I have good reason to believe that this one will not prove worthless...

April 4th, 1901

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.

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.

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 opinion of the world does not affect me. I have placed as the real values in my life what follows when I am dead.

...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.

To me, relativity is just a mass of error, deceptive, and violently opposed to the teachings of great men of science gone before, and even to common sense. The theory wraps all these errors and fallacies and clothes them in a mathematical god which fascinates, dazzles, and makes people blind to underlying error.

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 can not 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.

Am I think over it now it seems to me, that only men absolutely stricken with blindness, insensible to the greatness of nature, can hold that this planet is the only one inhabited by intelligent beings.

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.
