On his years of research in developing the electric light bulb, as quoted in "Talks with Edison" by George Parsons Lathrop in Harper's magazine, Vol. 80 (February 1890), p. 425.
Context: During all those years of experimentation and research, I never once made a discovery. All my work was deductive, and the results I achieved were those of invention, pure and simple. I would construct a theory and work on its lines until I found it was untenable. Then it would be discarded at once and another theory evolved. This was the only possible way for me to work out the problem. … I speak without exaggeration when I say that I have constructed 3,000 different theories in connection with the electric light, each one of them reasonable and apparently likely to be true. Yet only in two cases did my experiments prove the truth of my theory. My chief difficulty was in constructing the carbon filament.... Every quarter of the globe was ransacked by my agents, and all sorts of the queerest materials used, until finally the shred of bamboo, now utilized by us, was settled upon.

Anarchist Morality http://dwardmac.pitzer.edu/anarchist_Archives/kropotkin/AM/anarchist_moralitytc.html (1890)
Context: The history of human thought recalls the swinging of a pendulum which takes centuries to swing. After a long period of slumber comes a moment of awakening. Then thought frees herself from the chains with which those interested — rulers, lawyers, clerics — have carefully enwound her.
She shatters the chains. She subjects to severe criticism all that has been taught her, and lays bare the emptiness of the religious political, legal, and social prejudices amid which she has vegetated. She starts research in new paths, enriches our knowledge with new discoveries, creates new sciences.
But the inveterate enemies of thought — the government, the lawgiver, and the priest — soon recover from their defeat. By degrees they gather together their scattered forces, and remodel their faith and their code of laws to adapt them to the new needs.

The Structure of the Universe: An Introduction to Cosmology (1949)
Context: Minkowski made a remarkable discovery concerning the Lorentz formulae. He showed that, although each observer has his own private space and private time, a public concept which is the same for all observers can be formed by combining space and time as a kind of 'distance' by multiplying it by the velocity of light, c; in other words, with any time interval we can associate a definite spatial interval, namely the distance which light can travel in empty space in that period. If, according to a particular observer, the difference in time between any two events is T, this associated spatial interval is cT. Then, if R is the space-distance between these two events, Minkowski showed that the difference of the squares of cT and R has the same value for all observers in uniform relative motion. The square root of this quantity is called the space-time interval between two events. Hence, although time and three-dimensional space depend on the observer, this new concept of space-time is the same for all observers.<!--p.64
