“Relativity was born of an epistemological shock; it was born of the "failure" of the Michelson experiment. ...Is so little required to "shake" the universe of spatiality? Can a single experiment... annihilate... two or three centuries of rational thought? Yes, a single decimal sufficed, as our poet Henri de Regnier would say, to "make all nature sing." ...The Michelson experiment, at first so particular in character, will form the basis of the most far-reaching generalization.”

“Now, the velocity of wave propagation can be seen, without the aid of any mathematical analysis, to depend on the elasticity of the medium and its density; for we can see that if a medium is highly elastic the disturbance would be propagated at a great speed.”

“It appears, from all that precedes, reasonably certain that if there be any relative motion between the earth and the luminiferous ether, it must be small; quite small enough entirely to refute Fresnel's explanation of aberration.”
