As far as I see, such a theory [of the primeval atom] remains entirely outside any metaphysical or religious question. It leaves the materialist free to deny any transcendental Being. Georges Lemaître

A mathematical theory is not to be considered complete until you have made it so clear that you can explain it to the first man whom you meet on the street. David Hilbert

My object will be, first, to show by what connections the history of the fossil bones of land animals is linked to the theory of the earth and why they have a particular importance in this respect. Georges Cuvier

I have little hesitation in saying that as a result a sickly pall now hangs over the big bang theory. As I have mentioned earlier, when a pattern of facts becomes set against a theory, experience shows that it rarely recovers. Fred Hoyle

The cry of the conductor 'Clapham Road', awakened me from my dreaming: but I spent part of the night in putting on paper at least sketches of these dream forms. This was the origin of the 'Structural Theory'. August Kekulé

The major novelty of my theory was its claim that the most rapid evolutionary change does not occur in widespread, populous species, as claimed by Most geneticists, but in small founder populations. Ernst Mayr

The history of science knows scores of instances where an investigator was in the possession of all the important facts for a new theory but simply failed to ask the right questions. Ernst Mayr

Why has not anyone seen that fossils alone gave birth to a theory about the formation of the earth, that without them, no one would have ever dreamed that there were successive epochs in the formation of the globe. Georges Cuvier

It may be fair to say that these were the first experiments to give physicists in the United States a conviction of the fundamental validity of the quantum theory. Arthur Compton

If the future development of quantum theory happens to turn in that direction, we could conceive the beginning of the universe in the form of a unique atom, the atomic weight of which is the total mass of the universe. Georges Lemaître

Evolution as such is no longer a theory for a modern author. It is as much a fact as that the earth revolves around the sun. Ernst Mayr
