Strana 449 - Principia, 2nd edition. something is transmitted from one particle to another at a distance, what is its condition after it has left the one particle and before it has reached the other...
Strana 19 - Parti. 1o*. 6d. Vol. II. The Sacred Laws of the Aryas, as taught in the Schools of Apastamba, Gautama, VasishiAa, and Baudhayana. Translated by Prof. GEORG BUHLER. Part I. IOS. 6d. Vol. III. The Sacred Books of China. The Texts of Confucianism.
Strana 270 - If we differentiate the first of these equations with respect to x, and the second with respect to y, and add the...
Strana 181 - Returning to the phenomena in question, the first thought that arises in the mind is, that the electricity circulates with something like momentum or inertia in the wire, and that thus a long wire produces effects at the instant the current is stopped, which a short wire cannot produce. Such an explanation is, however, at once set aside by the fact, that the same length of wire produces the effects in very different degrees, according as it is simply extended, or made...
Strana 393 - But the properties of bodies are capable of quantitative measurement. \Ve therefore obtain the numerical value of some property of the medium, such as the velocity with which a disturbance is propagated through it, which can be calculated from electromagnetic experiments, and also observed directly in the case of light. If it should be found that the velocity of propagation of electromagnetic disturbances is the same as the velocity of light, and this not only in air, but in other transparent media,...
Strana 449 - In fact, whenever energy is transmitted from one body to another in time, there must be a medium or substance in which the energy exists after it leaves one body and before it reaches the other, for energy, as Torricelli remarked, 'is a quintessence of so subtile a nature that it cannot be contained in any vessel except the inmost substance of material things'.
Strana 146 - It must be carefully remembered, that the mechanical force which urges a conductor carrying a current across the lines of magnetic force, acts, not on the electric current, but on the conductor which carries it.
