Page 39 - That gravity should be innate, inherent, and essential to matter, so that one body may act upon another at a distance, through a vacuum, without the mediation of anything else, by and through which their action and force may be conveyed from one to another, is to me so great an absurdity, that I believe no man who has in philosophical matters a competent faculty of thinking can ever fall iuto it. Gravity must be caused by an agent acting constantly according to certain laws; but whether this agent...
Page 211 - ... the ratio between the sine of the angle of incidence and the sine of the angle of refraction is a constant, depending only upon the nature of the two media.
Page 39 - It is inconceivable that inanimate brute matter should, without the mediation of something else which is not material, operate upon and affect other without mutual contact; as it must do if gravitation, in the sense of Epicurus, be essential and inherent in it.
Page 88 - I went into the cube and lived in it, and using lighted candles, electrometers, and all other tests of electrical states, I could not find the least influence upon them, or indication of anything particular given by them, though all the time the outside of the cube was powerfully charged, and large sparks and brushes were darting off from every part of its outer surface.
Page 95 - ... electroscope E, and let C be a round brass ball insulated by a dry thread of white silk, three or four feet in length, so as to remove the influence of the hand holding it from the ice-pail below. Let A be perfectly discharged, and let C, after being charged at a distance, be introduced into A as in the figure.
Page 57 - Rise of a Liquid between Two Plates. — When two parallel plates are placed vertically in a liquid the liquid rises between them. If we now suppose fig. 6 to represent a vertical section perpendicular to the plates, we may calculate the rise of the liquid. Let...
Page 263 - ... of causing phosphorescence in bodies on which they fall. Substances known to be phosphorescent under ordinary circumstances shine with great splendour when subjected to the negative discharge in a high vacuum. Thus...
Page 113 - I arrive at are: first, that when two equal small conducting surfaces equally placed in air are electrified, one positively and the other negatively, that which is negative can discharge to the air at a tension a little lower than that required for the positive ball : second, that when discharge does take place, much more passes at each time from the positive than from the negative surface (1491.).
Page 304 - Lussac, the augmentation of volume which a gas receives when the temperature increases 1° is a certain fixed proportion of its initial volume at o°C ; while according to Dalton, a gas at any temperature increases in volume for a rise of 1° by a constant fraction of its volume at that temperature.
Page 390 - ... the rate of change of the flux. Faraday's first law of electrolysis ( 1832): the mass of any product liberated in electrolysis is proportional to the quantity of electricity passed through the electrolyte. Faraday's second law of electrolysis (1833): the masses of products liberated in electrolysis by the same quantity of electricity are in the ratio of their respective chemical equivalents.
