If I were ever assailed by doubt of ultimate success I would dismiss it by remembering the words of that great philosopher, Lord Kelvin, who after witnessing some of my experiments said to me with tears in his eyes: 'I am sure you will do it.'

You may live to see man-made horrors beyond your comprehension.October, 1947Source:
Our senses enable us to perceive only a minute portion of the outside world.January 7th, 1905
When wireless is perfectly applied the whole earth will be converted into a huge brain, which in fact it is, all things being particles of a real and rhythmic whole. We shall be able to communicate with one another instantly, irrespective of distance. Not only this, but through television and telephony we shall see and hear one another as perfectly as though we were face to face, despite intervening distances of thousands of miles; and the instruments through which we shall be able to do this will be amazingly simple compared with our present telephone. A man will be able to carry one in his vest pocket.January 30th, 1926Source:
The progressive development of man is vitally dependent on invention. It is the most important product of his creative brain. Its ultimate purpose is the complete mastery of mind over the material world, the harnessing of the forces of nature to human needs. This is the difficult task of the inventor who is often misunderstood and unrewarded. But he finds ample compensation in the pleasing exercises of his powers and in the knowledge of being one of that exceptionally privileged class without whom the race would have long ago perished in the bitter struggle against pitiless elements. Speaking for myself, I have already had more than my full measure of this exquisite enjoyment; so much, that for many years my life was little short of continuous rapture.February, 1919Source:
Th[e] problem was rendered extremely difficult, owing to the immense dimensions of the planet... But by gradual and continuous improvements of a generator of electrical oscillations... I finally succeeded in reaching rates of delivery of electrical energy actually surpassing those of lightning discharges... By use of such a generator of stationary waves and receiving apparatus properly placed and adjusted in any other locality, however remote, it is practicable to transmit intelligible signals, or to control or actuate at will any one apparatus for many other important and valuable purposes.May 16th, 1900
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.
It is a simple feat of scientific electrical engineering — only expensive — blind, faint-hearted, doubting world.January 7th, 1905
...Furthermore, an inducement must be offered to those who are engaged in the industrial exploitation of natural sources of power, as waterfalls, by guaranteeing greater returns on the capital invested than they can secure by local development of the property...June, 1900
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.July 18th, 1891Source:
