Your chemical lecturers you may go downstairs now and ask, if you disbelieve me always cheat over the indestructibility of matter experiment always. And then another a physiography thing. You know the experiment I mean? To demonstrate the existence of the earth's rotation. They use they use " "Foucault's pendulum," said Lewisham.
I cannot persuade myself to believe that a little star in its twinkling turned round Foucault's pendulum in the Paris Exhibition of 1861. Of course anything is believable when a definite physical connexion has been demonstrated, for example the influence of sunspots. Here all demonstration is lacking in the form of any coherent theory.
Sophia consented to the business proposition; for she had nothing else whatever in prospect, and she shared Madame Foucault's rosy view about the remunerativeness of the bedrooms. With three tenants who took meals the two women would be able to feed themselves for nothing and still make a profit on the food; and the rents would be clear gain.
Foucault's entire apparatus in 1862 had been enclosed in a single room; Newcomb's revolving and fixed mirrors, between which the rays of light were to run their timed course, were set up on opposite shores of the Potomac, at a distance of nearly four kilometres. Just as these experiments were concluded in 1882, M. Magnus Nyrén, of St.
The disinfecting of the flat had become an obsession with Sophia the obsession of a convalescent whose perspective unconsciously twists things to the most wry shapes. She had had trouble on the day before with Madame Foucault, and she was expecting more serious trouble when the moment arrived for ejecting Madame Foucault as well as all her movable belongings from Madame Foucault's own room.
Clothes were hung up in disorder on rough nails; among them she recognized a dressing-gown of Madame Foucault's, and, behind affairs of later date, the dazzling scarlet cloak in which she had first seen Madame Foucault, dilapidated now. So this was Madame Foucault's room! This was the bower from which that elegance emerged, the filth from which had sprung the mature blossom!
I confess that I did not think of it chiefly as a sacred edifice, or as the resting-place, more or less secure, of the "grands hommes" to whom it is dedicated. I was thinking much more of Foucault's grand experiment, one of the most sublime visible demonstrations of a great physical fact in the records of science.
She prowled into all the corners of the flat; but she discovered no more rooms, nothing but a large cupboard crammed with Madame Foucault's dresses. Then she went back to the large bedroom, and enjoyed the busy movement and rattle of the sloping street, and had long, vague yearnings for strength and for freedom in wide, sane places.
But our science would be different in some respects had we never seen them. We should still have good reason, in Foucault's pendulum experiment, for supposing that the world rotated upon its axis, and that the sun was so far relatively fixed; but we should have no suspicion of the orbital revolution of the world.
Foucault's conclusion from this admirable experiment was 'that the arc is a medium which emits the rays D on its own account, and at the same time absorbs them when they come from another quarter. Here he stopped.
