He was dismissed to Altona in 1761 caused by his theological views going against the prevailing orthodoxy. While he stayed in Soroe he published his "Praktische Philosophie für alle Stände" 1758. </em> hardcover

Cavendish's paper: pp. 1-62. the torsion balance of Michell shown on the plates. <br/><br/><em>First German edition of Cavendish's famous paper in which he calculated the weight of the earth and determined its mass. He also as the first observed gravitational motion of minute portions of matter. He estimates the earth's mass to 66 x 10 to the potential of 24 kg. The original paper "Experiments to determine the Density of the Earth" appeared in Philosophical Transaction 1798."Cavendish published five papers between 1784 and 1809.With one exception they were comparatively minor productions.The exception was his determination of the density of the earth or weighing of the world in 1798 by means of John Michell's torsion balance. The apparatus consisted of two lead balls on either end of a suspended beam; these movable balls were attracted by a pair of stationary lead balls. Cavendish calculated the the force of attraction between the balls fro the observed period of oscillation of the balance and deduced the density of the earth from the force. He found it to be 5.48 times that of water. Cavendish was the first to observe gravitational motions induced by comparatively minute portions of ordinary matter.By weighing the world he rendered the law of gravitation complete. The law was no longer a proportionally statement but a quantitatively exact one; this was the most importent addition to the science of gravitation since Newton."DSB III p. 158. </em> unknown

174046843Paris L'Imprimerie Royale 1740. 4to. Without wrappers. Extracted from "Mémoires de l'Academie des Sciences. Année 1737". Pp. 205-227 a. 2 folded engraved plates. <br/><br/><em>First appearance of this extremely importent paper in which Clairaut directly confirms the rotation and the orbital movement of the Earth around the Sun and giving an indirect proof of the axiom that the velocity of light does not depend on whether the light source moves away or toward the observer. The Earth does move after all !!In 1728 James Bradley trying to measure the stellar parallax discovered stellar aberration - the angular displacement of the apparent direction of starlight due to the earth's motion - and attributed it to the combined effect of the finite velocity of light and the earth's orbital velocity. But Bradley had not given any theoretical proof but Clairaut did in the offered paper.Aberration is "the apparent change in direction of a source of light caused by an observers component of motion perpendicular to the impinging rays. During this time the telescope has moved a short distance causing the photons to reach a spot on the focal plane displayed from the former image position. This discovery provided the first direct physical confirmation of the Copernican theory. A second importent application of aberration has been its clear-cut demonstration that as is axiomatic to special relativity light reaching the earth has a velocity unaffected by the relative motion of the source toward or away from earth."McGraw-Hill "Concise Encyclopedia.". </em> unknown
