Page 275 - It is hardly necessary to add that anything which any insulated body or system of bodies can continue to furnish without limitation cannot possibly be a material substance ; and it appears to me to be extremely difficult, if not quite impossible, to form any distinct idea of anything capable of being excited and communicated in the manner in which heat was excited and communicated in these experiments except it be motion.
Page 574 - 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.
Page 103 - The squares of the periodic times of the planets are proportional to the cubes of their mean distances from the Sun.
Page 118 - Archimedes stated that a body immersed in a fluid is buoyed up by a force equal to the weight of the displaced fluid.
Page 165 - We conclude that equal volumes of different gases at the same temperature and pressure contain equal numbers of molecules.

Page 272 - Hypothesis states that equal volumes of gases at the same temperature and pressure contain equal numbers of molecules.
Page 22 - Change of momentum is proportional to the force and to the time during which it acts, and is in the same direction as the force; (3) To every action there is an equal and opposite reaction.
