Léon Foucault: Citations en anglais

“The phenomenon develops calmly, but it is invisible, unstoppable.”

On his pendulum experiment, as quoted in Pendulum : Léon Foucault and the Triumph of Science (2003) by Amir D. Aczel
Contexte: The phenomenon develops calmly, but it is invisible, unstoppable. One feels, one sees it born and grow steadily; and it is not in one's power to either hasten it or slow it down. Any person, brought into the presence of this fact, stops for a few moments and remains pensive and silent; and then generally leaves, carrying with him forever a sharper, keener sense of our incessant motion through space.

“You are invited to come to see the Earth turn, tomorrow, from three to five, at Meridian Hall of the Paris Observatory.”

Invitation cards which he sent out to the scientists of Paris, to witness his famous pendulum experiment on 3 February 1851, as quoted in Pendulum : Léon Foucault and the Triumph of Science (2003) by Amir D. Aczel

“To contribute usefully to the advance of science, one must sometimes not disdain from undertaking simple verifications.”

As quoted in The Life and Science of Léon Foucault : The Man Who Proved the Earth Rotates (2003) by William Tobin, p. 72, ISBN 0521808553
