A method is developed for finding the modular equation for the first order equation that is extended to cover a number of cases"" this in turn is extended to second and higher orders. The method involves finding suitable functions to integrate, starting from a part of the modular equation that is integrable, so that the whole equation is of this form.

He also looks at the equilibrium of a weight suspended from three elastic cords by looking, via analogy, to a special case of the problem for fluids.""In his 1748 paper, Euler in ""Reflexions sur quelques loix generales de la nature.."" starts by declaring his commitment to the least-action principle. 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. Euler called this quantity ""effort"".""Enestrom: E 146.‎

Submitting to Maupertuis, the Berlin Academy rose to defend him and demanded that the original of Leibniz’ letter (a copy had been sent to König from Switzerland) be presented. When it became clear that the original could not be found, Euler published, with the approval of the Academy, ""Exposé concernant l’examen de la lettre de M. de Leibnitz"" (1752), where, among other things, he declared the letter a fake.

‎First appearance of Eötvös's main paper on gravitational phenomena, which became the subject of his lifework, and in which he showed experimentally, that the inertial mass and the gravitational mass are proportional, a discovery that became ONE OF THE BUILDING STONES OF THE THEORY OF GENERAL RELATIVITY.""The second extremely important application of the Eötvös balance involved a predetermination of the rate of gravitational acceleration for different bodies. 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.).‎

(1821)"", recording one of the most influential discoveries in physics in the 19th Century, as Faraday here, as the very first, showed 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"" 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 ? 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 to undertake a short historical survey...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 ""electrical conflict"" surrounding the wiree 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 oneof 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 in the first French edition). 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).‎

Farr, a pioneer in the quantitative study of morbidity and mortality, was chief statistician of the General Register Office, Englands central statistical office. Influenced by Babbage, he had long been interested in the use of a calculating machine, such as Babbage's Difference Engine to compute life tables"" see page 854 of the present report, in which Farr refers to his 1843 letter on the subject to the registrar-general. Farr had seen and tested the machine's predecessor, the Scheutz Engine No. 2, when it was on display in London. It was at Farr's recommandation that the British government authorized in 1857 the sum of Pound 1200 for the Scheutz Engine no. 3 to be constructed by the firm Bryan Donkin, a manufacturer of machines for the color printing of bank notes and stamps....Farr's printing report, received by the Royal Society on March 17 of that year, was written while Scheutz Engine no. 3 was still ""in the course of construction by Messr. Donkin"" (p. 854).

‎These seminal papers constitutes the description of the first realization of artificial radioactivity produced by neutron bombardment, and it is the first demonstration of neutron-induced radioactivity. These highlights and his many other results have left their imprint on the most diverse parts of physics. Fermi was awarded the Nobel prize in 1938 for these discoveries.""Acting on this idea, (Fermi reasoned that neutrons should be more effective than alpha particles in producing radioactive elements because they are not repelled by the nuclear charge and thus have a much greater probability of entering the target nuclei) Fermi bombarded several elements of increasing atomic numbers with neutrons. He hoped to find an artificial radioactivity produced by the neutrons. His first success was with fluorine. The neutron source was a small ampul containing beryllium metal and radon gas. The detecting apparatus consisted of rather primitive Geiger-Müller counters. Immediately thereafter Fermi, with the help of Amaldi, D’Agostino, Rasetti, and Segrè, carried out a systematic investigation of the behavior of elements throughout the periodic table. In most cases they performed chemical analysis to identify the chemical element that was the carrier of the activity. In the first survey, out of sixty-three elements investigated, thirty-seven showed an easily detectable activity. The nuclear reactions of (n, a), (n, p), and (n, ?) were then identified, and all available elements, including uranium and thorium, were irradiated. In uranium and thorium the investigators found several forms of activity after bombardment but did not recognize fission. Fermi and his collaborators, having proved that no radioactive isotopes were formed between lead and uranium, put forward the natural hypothesis that the activity was due to transuranic elements. These studies, which were continued by Otto Hahn, Lise Meitner, Irène Joliot Curie, Frédéric Joliot, and Savitch, culminated in 1938 in the discovery of fission by Hahn and Fritz Strassmann.""(DSB).""The present papers are a summary of these letters (the letters from the team communicated almost weakly to ""Ricerca Scientifica"") for the English speaking readers. ""When we (Fermi and Segre) went to Cambridge, we discussed with him (rutherford), in great detail, our work. The work which had been accomplished up to that date by our group is summarized in a paper which was presented by Lord Rutherford to the Royal Society (Paper No. 98). The manuscript of this paper had been prepared in Rome and delivered to him in Cambridge. he read it immediately with great attention, made several corrections to improve our English, and turned it over to the Royal Society. I asked him whether it would be possible to obtain a speedy publication and he immediately answered ""What did you think I was President of the Royal Society for ?"" (Collected Papers of Enrico Fermi, Vol. I, p. 641).Volume 149 contains the importent joint paper on SUPERCONDUCTIVITY by the brothers FRITZ And H. LONDON ""The Electromagnetic Equations of the Superconductor"", pp. 71-88.""In 1933 shortly before Heinz London joined his brother at Oxford, W. Meissner and R. Ochsenfeld made a startling discovery. It was well known that currents in superconductors flow in such a way as to shield points inside the material from changes in the external magnetic field. This indeed is an obvious property of any resistance less medium, fully discussed by Maxwell in 1873 long before the discovery of superconductivity. But a superconductor does more. Whereas a zero resistance medium only counteracts changes in the field, it actually tends to expel the field present in its interior before cooling.... The London quickly saw its implications and in 1935 published a joint paper on the electrodynamics of superconductors, in which they replaced (paper by Deaver and Fairbanks) by a new phenomenological equation connecting the current with the magnetic rather than the electric field...

‎London, Harrison and Sons, 1905. Bound in recent marbled boards. Both papers extracted from ""Proceedings of the Royal Society of London"", vol. 74, With title-page to volume 74. Pp. 476-487 and pp. 488-498.‎

‎First printing of these two seminal articles, in which the basic principle of the modern wireless valve, also called the ""Fleming Valve"", is introduced for the first time, making radio-telephony and broadcasting possible. ""The immense superiority of the Fleming thermionic valve to all previous detectors of wireless waves caused it to be widely used as an efficient and reliable detector."" (PMM). When Lee DeForest perfected the ""grid"" in 1907, Fleming's wireless signals could be amplified to the degree necessary to make radio-telephony and broadcasting possible. The Edison effect was first described in a paper by William Henry Preece, who was shown an experiment by Edison ""On a peculier of Glow-Lamps when raised to high Incasdence"", 1885. This effect was known as the ""Edison effect"", and in 1890 Fleming, an electrical engineer who had worked with Edison Company in London and was now professor at University College, began a careful study of this phenomenon in carbon filament lamps. In 1904 he was able to demonstrate that this occurred not only with electric waves but also with wireless waves. He thus introduced the basic principle of the modern wireless valve, which permits only unilateral conductivity. (see PMM No. 396).Shiers, Early Television.

‎First printing of this important paper relating Flinder's observations on the ship ""Investigator"" when exploring the coast of Australia. IN THE PAPER THE NAME ""AUSTRALIA"" APPEARS PROBABLY FOR THE FIRST TIME IN A SCIENTIFIC MEMOIR (p. 247).The name Australia was popularised by Matthew Flinders, who pushed for the name to be formally adopted as early as 1804. When preparing his manuscript and charts for his 1814 A Voyage to Terra Australis, he was persuaded by his patron, Sir Joseph Banks, to use the term Terra Australis as this was the name most familiar to the public. Flinders did so, but allowed himself the footnote:""Had I permitted myself any innovation on the original term, it would have been to convert it to Australia"" as being more agreeable to the ear, and an assimilation to the names of the other great portions of the earth."" In the paper offered he used the name ""Australia"" as early as 1806.""Captain Matthew Flinders RN (16 March 1774 - 19 July 1814) was one of the most successful navigators and cartographers of his age. In a career that spanned just over twenty years, he sailed with Captain William Bligh, circumnavigated Australia and encouraged the use of that name for the continent, which had previously been known as New Holland. He survived shipwreck and disaster only to be imprisoned for violating the terms of his scientific passport by changing ships and carrying prohibited papers. He identified and corrected the effect upon compass readings of iron components and equipment on board wooden ships and he wrote what may be the first work on early Australian exploration A Voyage to Terra Australis.""(Wikepedia)‎
