Pàgina 38 - It is inconceivable, that inanimate brute matter should, without the mediation of something else, which is not material, operate upon, and affect other matter without mutual contact; as it must do, if gravitation, in the sense of Epicurus, be essential and inherent in it.
Pàgina 152 - When a ray of light passes from one medium to another, it is refracted so that the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the velocities in the two media.
Pàgina 53 - ... is equal to the weight of a column of water whose base is the section of the piston, and whose height is the distance of the level of the water in the barrel AC, above the level in the reservoir.
Pàgina 116 - Heat is a motion, expansive, restrained, and acting in its strife upon the smaller particles of bodies. But the expansion is thus modified: while it expands all ways, it has at the same time an inclination upwards. And the struggle in the particles is modified also: it is not sluggish, but hurried and with violence.
Pàgina 59 - The preceding principles prove that every body immersed in a liquid is submitted to the action of two forces : gravity which tends to lower it, and the buoyancy of the liquid which tends to raise it with a force equal to the weight of the liquid displaced.
Pàgina 23 - L, consequently, any one of them must be equal and opposite to the resultant of the other two.
Pàgina 116 - Heat is a very brisk agitation of the insensible parts of the object, which produces in us that sensation from whence we denominate the object hot ; so what in our sensation is heat, in the object is nothing but motion.
Pàgina 79 - Boyle's law, and on the Continent Mario tte's law. It is as follows : — ' The temperature remaining the same, the volume of a given quantity of gas is inversely as the pressure which it bears' This law is easily verified by means of an apparatus called Boyle's tube (fig.
Pàgina 116 - To show the linear expansion of solids, the apparatus represented in fig. 2^3 may be used. A metal rod, A, is fixed at one end by a screw B, while the other end presses against the short arm of an index, K, which moves on 254 On Heat.
Pàgina 108 - No* between these two positions there is a third, at which if the flame be placed, it will burn silently; but if it be excited by the voice it will sing, and continue to sing. In this position, then, it is able to sing, but it requires start.
