Page 47 - We live in deeds, not years; in thoughts, not breaths; In feelings, not in figures on a dial. We should count time by heart-throbs. He most lives Who thinks most — feels the noblest — acts the best.
Page 109 - ... stories, the special relativity theory and the general theory of relativity. Since the time of the ancient Greeks it has been well known that in describing the motion of a body we must refer to another body. The motion of a railway train is described with reference to the ground, of a planet with reference to the total assemblage of visible fixed stars. In physics the bodies to which motions are spatially referred are termed systems of coordinates. The laws of mechanics of Galileo and Newton...
Page 112 - The great attraction of the theory is its logical consistency. If any deduction from it should prove untenable, it must be given up. A modification of it seems impossible without destruction of the whole. No one must think that Newton's great creation can be overthrown in any real sense by this or by any other theory. His clear and wide ideas will for ever retain their significance as the foundation on which our modern conceptions of physics have been built.
Page 93 - Do not Bodies act upon Light at a distance, and by their action bend its Rays; and is not this action (caeteris paribus) strongest at the least distance?
Page 112 - ... concerned. Thus the new theory of gravitation diverges widely from that of Newton with respect to its basal principle. But in practical application the two agree so closely that it has been difficult to find cases in which the actual differences could be subjected to observation. As yet only the following have been suggested : 1. The distortion of the oval orbits of planets round the sun (confirmed in the case of the planet Mercury). 2. The deviation of light-rays in a gravitational field (confirmed...
Page 73 - Ptolemaic spheres and all mechanical connection and assume a -force of gravitation attracting all bodies in proportion to their masses and inversely proportional to the squares of the distances separating them.
Page 112 - By an application of the theory of relativity to the taste of the readers, to-day in Germany I am called a German man of science, and in England I am represented as a Swiss Jew. If I come to be regarded as a bete noire...
Page 107 - After the lamentable breach in the former international relations existing among men of science, it is with joy and gratefulness that I accept this opportunity of communication with English astronomers and physicists.
Page 109 - Physicists owe their confidence in this proposition to the Maxwell-Lorentz theory of electro-dynamics. The two principles which I have mentioned have received strong experimental confirmation, but do not seem to be logically compatible. The special relativity theory achieved their logical reconciliation by making a change in kinematics, that is to say, in the doctrine of the physical laws of space and time. It became evident that a statement of the coincidence of two events could have a meaning only...
