‎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 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.

He suggested that the new radiation consisted of uncharged particles of approximately the mass of the proton, and he performed a series of experiments verifying his suggestion. These uncharged particles were called neutrons.""The discovery of the neutron completely revolutionized the physics of the atomic nucleus, both experimentally and theoretically.

‎Scarce offprint issue, from the library of the influential English physicist and astronomer James Hopwood Jeans, of Chandrasekhar's important paper in which he developed his statistical theory of stellar encounters. In the 1983 he was awarded the Nobel Prize in physic for key discoveries that led to the currently accepted theory on the later evolutionary stages of massive stars.Chandresekhar is famous for showing that the final fate of a star depends on its mass, furthermore he calculated that massive stars would be unable to evolve into white dwarfs, the limiting size called the Chandresekhar Limit.""An important question from the point of view of what can be observed is how the cumulative effect of chance encounters affects the orbit of a star measured by what is called ""time of relaxation"" of the stellar system. Conventional wisdom assumed it could be theoretically calculated by considering the cumulative effect of a large number of two-body encounters. A closer analysis convinced Chandrasekhar that such an idealization did not provide a good approximation to the physical situation in the stellar system. The gravitational field fluctuated in space and time. New methods of treating the problem based on statistics were required. He laid the foundations of such new methods in one of his most celebrated and widely quoted papers, ""Stochastic and Statistical Problems in Astronomy,"" published in 1943. The probability methods reviewed in this paper have found application beyond astronomy in a wide variety of problems and fields as different as colloidal chemistry and stellar dynamics."" (DSB) James Hopwood Jeans (1877 -1946) made several important contributions in many areas of physics, including quantum theory, the theory of radiation and stellar evolution. His analysis of rotating bodies led him to conclude that Laplace's theory that the solar system formed from a single cloud of gas was incorrect, proposing instead that the planets condensed from material drawn out of the sun by a hypothetical catastrophic near-collision with a passing star. This theory is not accepted today. Furthermore he is the founder of British cosmology.‎

‎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 any event, he now wished to assert that the work which can be done by heat in any change of the arrangement of a body is proportional to the absolute temperature multiplied by a function of molecular arrangement, the disgregation Z. Given this assumption and his postulate that the heat in a body H was only a function of temperature, he was able (1) to prove his theorem of the equivalence of transformations and (2) to separate the equivalence function (entropy) into a temperature-dependent term and a configurational-dependent term...""(DSB).The issue contains other notable papers, Plücker ""Ueber recurrente Ströme und ihre Anwendung zur Darstellung von Gasspectra"", pp. 27-54, Tyndall ""Ueber Strahlung und Absorption der Wärme durch gasförmige Materie"", pp. 1-27.‎
