The desire that guides me in all I do is the desire to harness the forces of nature to the service of mankind.

July, 1934

It would be impossible to describe the many wonderful things that the inventor (Nikola Tesla) showed Mr. Rouss and the reporter. Electricity no longer seemed a new force, but a living thing, capable of putting life and motion into even inanimate objects.

April 3rd, 1896

Not only for the physical achievement of your researches on high frequencies which laid the basic foundation of the great industry of radio transmission in which I have labored, but for the incessant inspiration of your early writings and your example, do l owe you an especial debt of gratitude.


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.

I do not believe in laziness, and I should like to see the loafer wiped from the face or the earth; but I want that those who are willing to work should accomplish their results with the least labor and in the best way.

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.

The greatest energy of movement will be obtained when synchronism is maintained between the pump impulses and the natural oscillations of the system.

May, 1919

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.

May 19th, 1907

I am convinced that I today can send a message to a ship at sea and that those on board can understand it. If I cannot I am willing to lay my head on the guillotine.

Had Tesla published the measuring methods he developed in New York and Colorado Springs, his name would probably be frequently encountered in earlier textbooks and handbooks on electrical measurements at high frequencies. As it is, we can only remark his exceptional ingenuity in designing measuring devices and the accuracy with which he determined the resonance of oscillatory circuits. An especially interesting feature is his method using a lamp already heated up by a supplementary power source, greatly increasing its sensitivity to small amplitude changes around the resonance peak of the oscillatory circuit.
