‎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).‎

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 edition of Chladni’s landmark work on the production of sounds from solid bodies, inaugurating the field of acoustics. Here, he demonstrated the method by sprinkling sand on plates of glass or metal and drawing a bow down their sides to produce a visible vibration pattern called ""Chladni figures” or “Chladni patterns”. ""The production of sound from solid bodies was not clearly understood until Chladni devised the method of sand figures to illustrate the structure of vibrations in a solid body"" (Norman). Chladni ""was the first to reduce the general association between vibration and pitch to a tabular basis and thus to lay the foundation of the modern science of acoustics"" (PMM). In his famous 1787-experiment, Chladni drew a bow over a piece of centrally fixed metal plate covered with sand, and the vibration of the plate caused the sand to move and accumulate around the nodal lines where the surface remained still, forming Chladni figures. The experiments by Chladni are a corner stone of modern acoustics. However, the motion of particles before they settle to the nodal lines is still not very well understood, and only hypothetical models have been put forward. Chladni had visited the Paris Academy in 1808 and had demonstrated the vibration patterns before an audience that included not only the leading French scientists but Napoleon himself"" Napoleon set a prize for the best mathematical explanation but no satisfactory explanations came out of it. Napoleon famously remarked ""Chaldni mhas made sound visible"" (Dibner). Variations of this technique are still commonly used in the design and construction of acoustic instruments such as violins, guitars, and cellos. Since the 20th century, it has become more common to place a loudspeaker driven by an electronic signal generator over or under the plate to achieve a more accurate adjustable frequency. In quantum mechanics, Chladni figures (""nodal patterns"") are known to be related to the solutions of the Schrödinger equation for one-electron atoms, and the mathematics describing them was used by Erwin Schrödinger to arrive at the understanding of electron orbitals.Dibner 150PMM 233Norman 480Sparrow 39‎

""In 1934 Senator Corbino, head of the physics department at the University of Rome, urged Enrico Fermi and his collaborators, among whom was Brune Pontecorvo, to patent a proces they had perfected for the production of artificial radio-activity by slow neutron bombardement. This process was a by-product of repetitions and enlargements of a discovery by Irene Curie and her husband Fredeic Joliot that the bombardment of certain light elements with alpha particles induced radio-activity. Further experiments conducted in 1938 at Berlin by Hahn and Strassmann were reported by Lise Meitner...She and her nephew, O.R. Frisch, working with Niels Bohr's laboratory, found the true explanation of these phenomena. The interpolation of a neutron into the nucleus of a uranium atom caused it to divide into two parts and to release energy amounting to about 200,000,000 electron volts. This process bore such a close similarity to the division of a living cell that Frisch suggested the use of the term 'fission' to describe it.....Halban, Jolio and Kowarski established the theoretical possibility of a self-perpetuating reaction...""

‎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..."").‎

Clausius (in the papers offere) critized helmholtz on his theory of heat over the consistency of the physical interpretation and of the use mathematics.
