‎First printing of Elsasser's paper on the Hydromagnetic Dynamo Theory. Elsasser, considered the father of the presently accepted dynamo theory as an explanation of the Earth's magnetism, proposed that this magnetic field resulted from electric currents induced in the fluid outer core of the Earth. He revealed the history of the Earth's magnetic field through pioneering the study of the magnetic orientation of minerals in rocks.""His [Elsasser] main attention became focused on a research field he had been cultivating almost as a diversion alongside his official duties since the late 1930s: geomagnetism. Discounting a hypothesis popularized by Einstein and Patrick Maynard Stuart Blackett that Earth's magnetic field is a property of its rotation per se, he thought instead of a self-sustaining dynamo in the molten metallic core. A key clue for Elsasser in his approach to the problem was a similarity between maps of the long-term variations in Earth's magnetic field and the maps of atmospheric flows familiar from his work in meteorology. Elsasser theorized that Coriolis forces and convection currents in the conductive liquid combined to produce poloidal magnetic and toroidal electric fields (the former extending beyond Earth's surface, the latter interior to it) that had a feedback effect on each other. Though some details were unclear, he argued that the dynamo theory gave the right order of magnitude for the magnetic field's strength and potentially accounted for its secular variations. By the mid-1950s, Elsasser's junior colleague at Utah, Eugene Newman Parker, and the British physicists Edward Crisp Bullard and the Australian-born George Keith Batchelor had explored alternative dynamo models and elaborated the mathematics showing that the field was self-sustaining. The dynamo theory ultimately received wide acceptance. It subsequently also became a key element of Hannes Alfvén's Nobel Prize-winning work on plasma electrodynamics. In the 1960s, Elsasser's geophysical interests moved into modeling seismic deformation in the context of the burgeoning theory of plate tectonics."" (DSB)‎

‎First printing of Epstein's seminal paper in which he was able to derive equations for the linear and quadratic Stark effect in hydrogen.""In his classic paper on the theory of the Stark effect [The present], the splitting of the spectral lines in a hydrogen atom by a strong electric field, he worked out the quantization rules in an invariant form and then used them to calculate the splitting of the hydrogen lines. The splitting effect, first observed by Johannes Stark in 1913, could not be explained along classical lines. Showing that Niels Bohr's Quantum description of the hydrogen atom could solve the problem made Epstein's reputation as a theoretical physicist. The match between his theoretical predictions and Stark's data furnished striking support for the RutherfordBohr atomic theory.Working independently, the German astronomer Karl Schwarzschild publicly announced the solution to the same problem one day after Epstein's paper appeared. (As Epstein relates it, Schwarzchild initially had the wrong formula. He corrected it after seeing an announcement of the development of Epstein's result.) Epstein's other contributions to the development of the quantum theory of atomic structure between 1916 and 1921 ranged from his extension of Bohr's theory to nonperiodic motions, including beta decay and the photoelectric effect, to the interference of spectral lines.""

‎In 1751, Maupertuis' priority for the principle of least action was challenged in print (Nova Acta Eruditorum of Leipzig) by an old acquaintance, Johann Samuel Koenig, who quoted a 1707 letter purportedly from Leibniz that described results similar to those derived by Euler in 1744. However, Maupertuis and others demanded that Koenig produce the original of the letter to authenticate its having been written by Leibniz. Koenig only had a copy and no clue as to the whereabouts of the original. Consequently, the Berlin Academy under Euler's direction declared the letter to be a forgery and that its President Maupertuis could continue to claim priority for having invented the principle.Enestroem: 182.‎

His expression corresponds to what we would now call potential energy, so that his statement of least action (formulated by Maupertuis in 1746) in statics is equivalent to the principle that a system of bodies at rest will adopt a configuration that minimizes total potential energy.

‎Three first editions by Euler. Euler's goal in the first paper is to show that certain phenomena that resulted from the eclipse of July 25, 1748 are evidence that the moon has an atmosphere that is almost 200 times less dense than that of the earth. (The phenomena Euler observed are optical effects of light passing close to a sharp edge, and not the refraction of a lunar atmosphere).The other papers on the physics of rigid bodies are groundbreaking as Euler here set forth what is known as ""Euler's dynamical equations of the motion of the mass-center of any solid"", and thus STATING FOR THE FIRST TIME THE LAW OF DRY FRICTION, mathematically. Euler explains his experiments with the inclined plane and discovers the DIFFERENCE BETWEEN KINETIC AND STATIC FRICTION.""Leonhard Euler occupied himself with the mathematical point of view of friction as well as the experimental. He introduced the differentiation between static frictional forces and kinetic frictional forces, and solved the problem of rope friction, probably the first contact problem to be analytically solved in history. (1750, the papers offered). He was the first to lay the foundations of the mathematically way of dealing with the law of dry friction and in this way promoted further development. We have to thank for the symbol as the coefficient of friction. Euler worked with the idea that friction originates from the interlocation, between small triangular irregularities.This understanding survived, in different variations,for a hundred years and is also used today as the ""Tomlinson Model"" in connection with friction on atomic scale.""(L.
