Nikola Tesla

The gift of mental power comes from God, Divine Being, and if we concentrate our minds on that truth, we become in tune with this great power.

I do not think you can name many great inventions that have been made by married men.

I myself have made my own discoveries in the greatest solitude, and when I have been alone, undisturbed.

I have not married, so that I may devote myself entirely to my work.

I loved that pigeon as a man loves a woman, and she loved me. As long as I had her, there was a purpose to my life.

My brain is only a receiver, in the Universe there is a core from which we obtain knowledge, strength and inspiration. I have not penetrated into the secrets of this core, but I know that it exists.

I have toiled ceaselessly for a quarter of a century for the love of science, to benefit humanity.

Of all the frictional resistances, the one that most retards human movement is ignorance, what Buddha called 'the greatest evil in the world.'

The spread of civilization may be likened to a fire; first, a feeble spark, then a flickering flame, then a mighty conflagration, fiercely glowing and devouring.

The human being is a self-propelled automaton, and I am the biggest one in the world.

I do not hesitate to state here for the world that there is no electrical principle or device which I have not conceived and substantially perfected in my own mind.

I have harnessed the cosmic rays and caused them to operate a motive device.

I have created a new form of energy, which I call the 'death ray.'

It is not a death ray in the sense that it kills. It is a weapon that will make war impossible.

The greatest discoveries have been made by men of science who have not been afraid to depart from the beaten path.

I could only with difficulty understand the enthusiasm of others for any but engineering achievements.

From childhood I was compelled to concentrate attention on myself. This caused me much suffering, but, on the other hand, it developed in me powers of introspection and observation.

The human race is governed by its imagination.

I am unwilling to submit to any procedure for the determination of my mental condition.

I have always been much interested in the question of women's physical and mental superiority, and have found that women are the stronger sex.
