‎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.‎

It had been known from earlier work that all bodies fall with the same acceleration (in a vacuum), but the best previous determinations yielded only a limited accuracy. In response to a prize announcement by the University of Gottingen, Eötvös and his collaborators followed up his early measurements on this subject. The new measurements provided not merely a more accurate proof of a principle believed right until then, but much more: his results, proving that gravitational mass and inertial mass are equivalent, the possible deviation being about five parts in 109, became one of the building stones of the theory of general relativity. The experiment proves the “weak” form of the principle of equivalence, which states that the trajectory of a test particle, under the influence of gravitational fields only, depends only on its initial position and velocity, not on its mass and nature. Later confirmation of his results (during the last fifty years) reduced the possible deviation from perfect equivalence by a factor of 1,000."" (DSB, IV, 379 ff.).‎

‎First appearance of this important paper in which Eötvös set forth his ""Law of Capillarity"" and thereby eliminating the errors that had twarted his predecessors such as Young, Laplace, Poisson and Gauss. The principle thus established, also called ""The weak equivalence Principle"", served as a BASIS FOR EINSTEIN'S THEORY OF RELATIVITY(Capillarity: the property or exertion of capillary attraction of repulsion, a force that is the resultant of adhesion, cohesion, and surface tension in liquids which are in contact with solids, causing the liquid surface to rise or be depressed...)""The beginnings of Eötvös’ scientific career are connected with liquids. He worked out a new way to determine surface tension, which subsequently became known as the reflection method. This method made it possible to determine precisely the surface tension of various liquids. During his experiments, Eötvós found a linear relationship between the molar surface energy of liquidsand their temperature. The proportionality factor is constant for all compound liquids independently of their composition. The molar surface energy is equal to the work needed to move one molecule from the inside of the liquid to its surface. Based on this finding, Eötvös was able to state the following relationship: with increasing temperature, the surface tension of a liquid decreases until, at the critical temperature, it becomes zero. Later this rule was named the Eótvös law and the proportionality constant the Eötvós constant. In case of liquids this constant is as fundamental as the universal gas constant in case of gases.""‎

‎First appearance in French of this landmark paper in electromagnetism. The present paper is a translation into French of Faraday's seminal paper ""On some New Electro-Magnetical Motions, and on the Theory of Magnetism"", which was originally published on October 21 in ""The Quaterly Journal of Science"", between one and two months before the present French version, which was published in ""Annales de Chimie et de Physique"", in December the same year. The work contains the first published mentioning of the ""LINE AND FORCE CONCEPT"". Faraday employed a magnet and a wire with a flowing current, caused each separately to rotate round the other, and concluded that a current-carrying wire is surrounded by a circular ""line"" of magnetic force.""Ever since Hans Christian Oersted's announcement of the discovery of electromagnetism in the summer of 1820, editors of scientific journals had been inundated with articles on the phenomenon...Inspired by the editor of Philosophical Magazine, Richard Phillips, Faraday agreed to undertake a short historical survey but he did so reluctantly, since his attention was focused on problems of chemistry rather remote from electromagnetism. His entusiasm was aroused in September 1821, when he turned to the investigation of the peculiar nature of the magnetic force created by an electrical current. Oersted had spoken of the ""electric conflict"" surrounding the wire and had noted that ""this conflict performs circles"", but this imprecise description had had little impact upon Faraday. Yet as he experimented he saw precisely what was happening. Using a small magnetic needle to map the pattern of magnetic force, he noted that one of the poles of the needle turned in a circle as it was carried around the wire. He immediately realized that a single magnetic pole would rotate unceasingly around the current-carrying wire so long as the current flowed. He then set about devising an instrument to illustrate this effect...and so his experiment records the FIRST CONVERSION OF ELECTRICAL INTO MECHANICAL ENERGY. (Based on the article in DSB).- Faraday's discovery of ""the lines of magnetic force"" became the starting point for the revolutionary theories of Clark Maxwell and later of Einstein.‎

‎These two important papers were presented to The Royal Academy at the same date, and stitched together from the Transactions.In his paper FARADAY observes importent relations between tension, pressure, temperature and gravitation as he proves that any kind of matter, not only air, ceases to assume the elastic form, whenever the gravitation of its particles is stronger than the elasticity of its vapour. The loss of tension necessary for effecting this object may be accomplished in two ways, either by extreme dilatation, or by cold.The paper by BBBAGE is the second of two papers on electromagnetism, the first written together with his friend J.F.W. Herschel.""The curious phenomena of electromagnetism were beginning to be discovered during this period, and inevitably Babbage took an interest. In the spring of 1825 Gay Lussac visited London and described Arago's experiments with rotating discs. Plates of copper and other substances set in rapid motion in a magnetic field and under a magnetized needle caused it to deviate from its direction, finally dragging it round with them. At this time Herschel was secretary of the Royal Society and had rooms in Devonshire Street. Babbage and he carried out some quite extensive experiments in Babbage's house. They tried the effect with discs of many different substances using Babbage's lathe: only metals and graphite showed the effect and they concluded that the conductivity of the disc was the importent point...however they did not solve the problem of electromagnetic induction: æater their friend Michael Faraday did.""(Hyman in ""Charles Babbage.

In the first paper he introduced for the first time the concept of ""LINE OF FORCE"" and hereby deliniating ""a picture of the universe as consisting of fields of various types, one that was more subtle, flexible, and useful than the purely mechanical picture of Galileo and Newton. The FIELD UNIVERSE was to be recognized with Maxwell half a century later and with Einstein, after an interval of another halfcentury.""(Asimov).""Ever since Hans Christian Oersted's announcement of the discovery of electromagnetism in the summer of 1820, editors of scientific journals had been inundated with articles on the phenomenon. Theories to explain it had multiplied, and the net effect was confusion. Were all the effects reported real ? Did the theories fit the facts ?

With presentation-inscription by Faraday in ink on title page: ""William Thomson Esq. | St. Peters College | from the Author."" (2),41,(1:blank) pp.‎

‎First edition, rare offprint-issue, of ""one of the great classics of chemistry and physics"". With an extremely attractive presentation-inscription from Faraday to William Thomson (later Lord Kelvin), who delivered the first mathematical exposition of Faraday's researches in electricity. Thomson provided an important theoretical direction for Faraday's interpretation of his own experiments and the two colleagues motivated and inspired each other to a degree that the research and knowledge of electricity they possessed and published would not have would have been reached until many years later. The paper itself is of the utmost importance, since much of Faraday's groundbreaking research published in 1831-1839 contained many shortcomings and errors which are corrected in this publication. ""The corrected second edition of volume 1 is preferred, because the first edition (London 1839) contained many errors"". (Neville, Historical Chemical Library).""In June 1849 William Thomson wrote to Michael Faraday suggesting that the concept of a uniform magnetic field could be used to predict the motions of small magnetic and diamagnetic bodies. [...] There had been an important exchange of ideas between the two, who had a common interest in explaining voltaic, electrostatic, magnetic, optical, and thermal phenomena. They meet every year between 1845 (where they became acquainted) and 1849"". (Gooding, Faraday, Thomson, and the Concept of the Magnetic Field).In 1845 Thomson gave the first mathematical development of Faraday's idea that electric induction takes place through an intervening medium, or ""dielectric"", and not by some imprecise ""action at a distance"". He also devised a hypothesis of electrical images, which became a powerful agent in solving problems of electrostatics, or the science which deals with the forces of electricity at rest. It was partly in response to his encouragement that Faraday undertook the research in September 1845 that led to the discovery of the Faraday Effect, which established that light and magnetic (and thereby electric) phenomena were related.Faraday was also the direct cause of William Thomson's work on the transatlantic submarine telegraph cable. In 1854, Faraday had demonstrated how the construction of a cable would limit the rate at which messages could be sent, which later would be termed the bandwidth. Thomson immediately looked into the problem and published his response the same month Faraday had published his observations. Thomson expressed his results in terms of the data rate that could be achieved and the economic consequences in terms of the potential revenue of the transatlantic undertaking. In 1855, Thomson stressed the impact that the design of the cable would have on its profitability. Thomson's work on the cable consequently resulted in a complete system for operating a submarine telegraph that was capable of sending a character every 3.5 seconds. He patented the key elements of his system, the mirror galvanometer and the siphon recorder, in 1858.From 1831 to 1852, Michael Faraday published his ""Experimental Researches in Electricity"" in The Philosophical Transactions of the Royal Society. These papers contain not only an impressive series of experimental discoveries, but also a collection of heterodox theoretical concepts on the nature of these phenomena expressed in terms of lines of forces and fields. He published 30 papers in all under this general title. They represent Faraday's most important work, are classics in both chemistry and physics, and are the experimental foundations for Maxwell's electro-magnetic theory of light, using Faraday's concepts of lines of force or tubes of magnetic and electrical forces. His many experiments on the effects of electricity and magnetism presented in these papers lead to the fundamental discoveries of 'induced electricity' (the Faraday current), the electronic state of matter, the identity of electricity from different sources, equivalents in electro-chemical decomposition, electrostatic induction, hydro-electricity, diamagnetism, relation of gravity to electricity, atmospheric magnetism, and many others.""Among experimental philosophers Faraday holds by universal consent the foremost place. The memoirs in which his discoveries are enshrined will never cease to be read with admiration and delight"" and future generation will preserve with an affection not less enduring the personal records and familiar letters, which recall the memory of his humble and unselfish spirit.""

Here Faraday investigates many electro-magnetic phenomena, tries to unite the different forces of nature, revises his theory of diamagnetic bodies, discovers magnetocrystallic effects, defines his key concept ""lines of force"" etc. etc.From 1831 to 1852 Michael Faraday published his ""Experimental Researches in Electricity"" in The Philosophical Transactions of the Royal Society. These papers contain not only an impressive series of experimental discoveries, but also a collection of heterodox theoretical concepts on the nature of these phenomena expressed in terms of lines of forces and fields. He published 30 papers in all under this general title.They represents Faraday's most importent work, are classics in both chemistry and physics and are the experimental foundations for Maxwell's electro-magnetic theory of light, using Faraday's concepts of lines of force or tubes of magnetic and electrical forces. His many experiments on the effects of electricity and magnetism presented in these papers lead to the fundamental discoveries of 'induced electricity' (the Farday current), the electronic state of matter, the identity of electricity from different sources, equivalents in electro-chemical decomposition, electrostatic induction, hydro-electricity, diamagnetism, relation of gravity to electricity, atmospheric magnetism and many other.""Among experimental philosophers Faraday holds by universal consent the foremost place. The memoirs in which his discoveries are enshrined will never ceaseto be read with admiration and delight"" and future generations will preserve with an affection not less enduring the personal records and familiar letters, which recall the memory of his humble and unselfish spirit.""(Edmund Whittaker in A History of the Theories of Aether and Electricity).‎

‎First appearance of these three papers in which Faraday records one of the most influential discoveries in physics in the 19th Century"" - with these papers he is the very first to show how to CONVERT THE ELECTRICAL AND MAGNETIC FORCES INTO CONTINUAL MECHANICAL MOVEMENT, thus creating the first electric motor, using the principle of electromagnetic rotation. In the first paper he introduced for the first time the concept of ""LINE OF FORCE"", hereby delineating ""a picture of the universe as consisting of fields of various types, one that was more subtle, flexible, and useful than the purely mechanical picture of Galileo and Newton. The FIELD UNIVERSE was to be recognized with Maxwell half a century later and with Einstein, after an interval of another half century"" (Asimov).""Ever since Hans Christian Oersted's announcement of the discovery of electromagnetism in the summer of 1820, editors of scientific journals had been inundated with articles on the phenomenon. Theories to explain it had multiplied, and the net effect was confusion. Were all the effects reported real? Did the theories fit the facts? It was to answer these questions that Phillips turned to Faraday and asked him to review the experiments and theories of the past months and separate truth from fiction,...Faraday agreed to undertake a short historical survey...His enthusiasm was aroused in September 1821, when he turned to the investigation of the peculiar nature of the magnetic force created by an electrical current. Oersted had spoken of the ""electrical conflict"" surrounding the wire and had noted that ""this conflict performs circles"".....Yet as he experimented he saw precisely what was happening. Using a small magnetic needle to map the pattern of magnetic force, he noted that one of the poles of the needle turned in a circle as it was carried around the wire. He immediately realized that a single magnetic pole would rotate unceasingly around a current-carrying wire so long as the current flowed. He then set about devising an instrument to illustrate this effect. His paper ""On some new Electro-Magnetical Motion, and on the Theory of Magnetism"" appeared in the 21 October 1821 issue of the ""Quarterly Journal of Science"" (The paper offered). It records the first conversion of electrical into mechanical energy. It also contained the first notion of the line of force."" (DSB IV, pp. 533).‎
