‎First edition of these papers, in which Cartan intruced the concept of ""Torsion"", the main inspiration for Einstein in his searce for a unified field theory. The ECT of gravity is a modification of the General relativity Theory""The Einstein-Cartan theory, also known as the Einstein-Cartan-Sciama-Kibble theory, is a classical theory of gravitation similar to general relativity but relaxing the assumption that the affine connection has vanishing antisymmetric part (torsion tensor), so that the torsion can be coupled to the intrinsic angular momentum (spin) of matter, much in the same way in which the curvature is coupled to the energy and momentum of matter. In fact, the spin of matter in curved spacetime requires that torsion is not constrained to be zero but is a variable in the principle of stationary action. Regarding the metric and torsion tensors as independent variables gives the correct generalization of the conservation law for the total (orbital plus intrinsic) angular momentum to the presence of the gravitational field. The theory was first proposed by Élie Cartan in 1922 and expounded in the following few years. Dennis Sciama and Tom Kibble independently revisited the theory in the 1960s, and an important review was published in 1976. Albert Einstein became affiliated with the theory in 1928 during his unsuccessful attempt to match torsion to the electromagnetic field tensor as part of a unified field theory. This line of thought led him to the related but different theory of teleparallelism."" (Wikipedia).‎

‎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 6,6 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.).The issue contains further papers by Ritter, Chladni et al.‎

‎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..."").‎

‎First appearance of these milestone papers in Quantum Physics, constituting the first step in Quantum Field Theory and the invention of the Second Quantifization Method. By these papers Dirac ""gave the foundation for that theory, quantum electrodynamics""(Pais).""A New Radiation Theory. Dirac liked his transformation theory because it was the outcome of a planned line of research and not a fortuitous discovery. He forced his future investigations to fit it. The first results of this strategy were almost miraculous. First came his new radiation theory, in February 1927, which quantized for the first time James Clerk Maxwell’s radiation in interaction with atoms. Previous quantum-mechanical studies of radiation problems, except for Jordan’s unpopular attempt, retained purely classical fields. In late 1925 Jordan had applied Heisenberg’s rules of quantization to continuous free fields and obtained a light-quantum structure with the expected statistics (Bose Einstein) and dual fluctuation properties. Dirac further demonstrated that spontaneous emission and its characteristics—previously taken into account only by special postulates—followed from the interaction between atoms and the quantum field. Essential to this success was the fact that Dirac’s transformation theory eliminated from the interpretation of the quantum formalism every reference to classical emitted radiation, contrary to Heisenberg’s original point of view and also to Schrödinger’s concept of ? as a classical source of field.This work was done during Dirac’s visit to Copenhagen in the winter of 1927. Presumably to please Bohr, who insisted on wave-particle duality and equality, Dirac opposed the ""corpuscular point of view"" to the quantized electromagnetic ""wave point of view."" He started with a set of massless Bose particles described by symmetric ? waves in configuration space. As he discovered by’ playing with the equations, ’ this description was equivalent to a quantized Schrödinger equation in the space of one particle"" this’ second quantization’ was already known to Jordan, who during 1927 extended it into the basic modern quantum field representation of matter. Dirac limited his use of second quantization electromagnetic to radiation: to establish that the corpuscular point of view, once brought into this form, was equivalent to the wave point of view.""(DSB).‎

Brewster had maintained the objective reality of three primary colors by supposing, in opposition to Newton, that there exist three distinct kinds of light, each of which excites in the eye one of the sensations red, yellow, or blue. Helmholtz regarded the theory as still another confusion of physical stimulus and subjective responce....He also revived Young's theory of color visoin...only to refute it. He had discovered that spectral colors, when mixed, always yield a duller color of less-than-spectral saturation. Therefore the whole idea that all colors may be obtained from mixtures of three primary colors must be incorrect, he concluded, for the spectral colorss, at least, can never be obtained in their full saturation by mixing any three of their number....Although Helmholtz dismissed Young's theory in 1852, by 1858 he had changed his mind and become its formost advocate. In order to save Ypoung's theory....Helmholtz asumed that Young's physiological primaries are not spectral colors att all, but colors of far greater-than-spectral saturation...""(DSB VI, pp. 246-247).
