‎---- EDITION ORIGINALE ---- BEL EXEMPLAIRE ---- TRES RARE RECUEIL PUBLIE PAR KOENIG dans lequel sont réunies les diverses publications qui ont paru à l'époque concernant la célèbre polémique relative au principe de moindre action qui opposa Maupertuis à Koenig. Euler et Voltaire prirent part au débat et publièrent à cette occasion : "Dissertation sur le principe de moindre action avec l'examen des objections de Mr. Le Professeur Koenig faites contre ce principe" (Euler), "Diatribe du Docteur Akakia, médecin du pape..." (Voltaire). Ces deux écrits sont au nombre de ceux réunis dans ces deux volumes ---- Pour plus de détails au sujet de cette célèbre querelle voir M. Gueroult : "Dynamique et métaphysique leibnitizienne" et plus particulièrement la note "Sur le principe de moindre action chez Maupertuis", pp. 215/235 ---- "Maupertuis clearly was successful in attracting to Berlin scientific luminaries who greatly enhanced the luster of the new Academy. Euler, one of the greatest mathematicians of the day, was already there. Matters were going well, when the celebrated "affaire Koenig" erupted : Samuel Koenig, a protégé of Maupertuis... submitted a dissertation attacking the validity of the principle of least action and then - most strangely for a devoted adherent of Leibnitz - ascribed the discredited law to the latter, citing a letter from Leibnitz to Hermann... The controversy touched off by this work, resulted in perhaps the ugliest of all the famous scientific disputes. Its principal figures were Koenig, Maupertuis, Euler and Voltaire. Maupertuis demanded that the letter be produced. Koenig produced a copy but stated that the original was in the hands of a certain swiss named Henzi... After exhautive search no trace of the letter was found in Henzi's belongings. Maupertuis then demanded that the Academy take action against Koenig... 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", where, among other things, he declared the letter a fake. The conflict grew critical when, later in the same year, Voltaire published his Diatribe du Docteur Akakia, defending Koenig and making laughingstocks of both Maupertuis and Euler...".

‎First printing of 4 importent early papers by Euler. Enestroem: E42, E43, E44 a. E45.E42: This is Euler's second paper on the ""Brachistochrone problem"".E43. Here Euler introduces THE EULER CONSTANT. ""The Euler-Mascheroni constant (also called Euler's constant) is a mathematical constant recurring in analysis and number theory, usually denoted by the lowercase Greek letter gamma.""E44: ""This is an extensive paper that develops a method for finding a family of curves arising from the constant of integration of dz = Pdx, which is treated as the second variable"" the rudiments of partial differentiation are presented, and there is an extensive survey of homogeneous functions centred around what is now know as Euler's Theorem for such functions. The origins of this paper would seem to be Proposition 15 of Vol. 2 of the Mechanica, relating to families of tautochronous curves, where an integration relying on Euler's Theorem is required."" (Ian Bruce).E45: Here Euler introduces the FUNCTION NOTATION f(x). ""This is an equally extensive paper that continues the development of methods for finding a family of curves arising from the constant of integration of dz = Pdx, which is treated as the second variable. 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. This paper is noteworthy in addition as it seems to be the first in which the function notation, albeit in a slightly different form from the modern meaning, is introduce. I have not been able to check all the equations at this stage.""(Ian Bruce).This section also contains DANIEL BERNOULLI: Demonstrationes theorematum svorum de oscillationibus corporum filo flexili connexorum et catenae verticaliter suspensae.

Il était notamment membre de l'Académie royale des sciences de Prusse à Berlin. Euler fit d'importantes découvertes dans des domaines aussi variés que le calcul infinitésimal et la théorie des graphes. Il introduisit également une grande partie de la terminologie et de la notation des mathématiques modernes, en particulier pour l'analyse mathématique, comme la notion de fonction mathématique. Il est aussi connu pour ses travaux en mécanique, en dynamique des fluides, en optique et en astronomie. Euler est considéré comme un éminent mathématicien du xviiie siècle et l'un des plus grands et des plus prolifiques de tous les temps. Une déclaration attribuée à Pierre-Simon de Laplace exprime l'influence d'Euler sur les mathématiques : « Lisez Euler, lisez Euler, c'est notre maître à tous ». Il était un fervent chrétien, croyant en l'inerrance biblique, et s'opposa avec force aux athées éminents de son temps. couverture à peine jaunie, sinon bel exemplaire, intérieur frais et propre‎

Large engraved frontispiece showing comets orbiting the sun and planets, 187 pp. and 4 copper engraved folding plates. A4 (pp.7-8) canceled - catchword continues. Complete.‎

‎First edition of this important work containing the first complete mathematical treatment of the two-body problem, consisting in a planet and the Sun. Great minds such as Newton, Bernoulli and Poincaré all made important contributions to solving the exceedingly important mathematical Two-Body Problem, but Euler here gave the first full exposition of it. ""In 1744, Euler developed the first completely analytical method for determining a parabolic orbit through successive approximations in his Theory of the Motion of Planets and Comets. This was built upon Newton's earlier work, which [...] tended to be very complex and messy and incomplete. Today, the method of successive approximation known to every student of calculus is known by this man's name, Euler's Method."" (Summy, Analysis of the Two-Body and Restricted Three-Body Problem, p. 4).In the present work Euler gives ""the solutions of the main problems of theoretical astronomy dealing with the structure, nature, motion and action of comets and planets. With regard to the theory of perturbed motion of celestial bodies, Euler formulated the perturbation theory in general terms so that it can be used to solve the mathematical problem of dynamic models and particular problems of theoretical astronomy [...] He gave an extensive mathematical treatment of the problem of improving approximations of orbits within the framework of the two-body problem and taking perturbations into account. In his Theoria motuum planetarum et cometarum published in 1744, Euler gave a complete mathematical treatment of the two-body problem consisting of a planet and the Sun."" (Debnath, The Legacy of Leonhard Euler, p. 364).In 1687, in the 'Principia', Newton had solved the problem geometrically" In 1710 Johann Bernoulli had proved that the motion of one particle with respect to the other is described by a conic section In 1734 Daniel Bernoulli won a French Academy prize for his analytical treatment of the Two Body problem - but it was Euler, with his present work, who gave the fully complete mathematical treatment of the problem.

‎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. Popov ""History of the Contact Mechanics and the Physics of Function"", p.3).Eneström: E142, E143, E144. ‎

‎Both papers first edition. The modern form of trigonometry as well of all trigonometry are due to Euler. Whereas trigonometry before Euler was concerned with trigonomic Lines, Euler's trigonometry deals with trigonomic Function. - ""In the first paper Euler constructs spherical trigonometry as the intrinsic geometry of the surface of the sphere. He expresses the line element ds of the surface in terms of the longitude and latitude of a point, defines the great circles as curves that minimize the integral of the line element, and, in connection with with the determination of the minimum of a side of a spherical triangle, derives 10 equations of spherical geometry.. After the discovery that the shape of the earth is that of a spheroid, Euler, (in the second paper here offered) extended his methods to spheroids. He develops this subject in its entirety...and here deduced very many of the formulas of spherical geometry"" (Rosenfeld & Abramovich). - Enestrom: E:214 a.

‎Scarce first German edition of his ""Introductio in analysin infinitorum"" from 1748, a work by which Euler lays the foundation of modern mathematical analysis, by summarizing his numerous discoveries in infinite series, infinite products, and continued fractions, and it is here he introduces the CONCEPT OF FUNCTION by the notation F(x), and defines it as any analytical expression formed in any manner from a variable quantity and constants. He includes polynomials, power series, and logarithmic and trigonometric expressions. He also defines a function of several variables. - ""Euler's book is one of the few books on mathematics that is mentioned by John Carter and Percy H. Muir in their Printing and the Mind of Man. There Euler is compared with Euclid: what Euclid did with his ""Elements"" for geometry, Euler did with his ""Introductio"" for analysis. It was by means of this textbook that analysis became an independent discipline within mathematics."" (Karin Reich in ""Landmark Writings in Western Mathematics""). Enestrom (Euler Archive): E 101-02 (Introductio) - Volume 3 is not listed by Enestrom, and it comprises 7 memoirs on equations, 2 by Euler and 5 by Lagrange. All 7 are first German translations as the memoirs originally appeared in Latin and French in St. Petersbourg Akad. der Wissenschaften and in Königl. Akademie der Wissenschaften zu Berlin. (Euler: translation of Enestrom E 30 (1738) and E 282 (1764)).The 5 memoirs by Lagrange consist of his famous contributions to the theory of algebraic equations originally published in French in Königl. Akademie der Wissenschaften zu Berlin 1769-73, here in the first German translations, and among these his groundbreaking ""Von der Auflösung der numerischen Gleichungen"" (Sur la Résolution des Équations Numèriques 1769), where he provides methods, by examining the roots of algebraic equations, of separating the real and imaginary roots of approximating the real roots with continued fractions.Enestrom E 101-102 (1. ed., not listing vol. 3) - PMM: 196 (Introductio).‎

‎First printing of both papers. The second is important as it contains Euler'is second proof of the Euler-Fermat theorem, which Euler presents as a consequence of the theorem that (a+b)p = ap+bp (mod p). This paper also includes results about possible divisors of a2n + b2n, and Euler uses this to show again that F5 is not prime. - Enestroem No. 133 a. 134.‎

‎First printing of Johann Albert Euler's importent paper in which he set forth the so-called ""Theorem of Johann-Albert Euler"", stating that the trajectory of a ball is a parabola followed by a straight line. The eldest son of Leonhard Euler was a prominent geometer in his own right. In 1758, Johann-Albert Euler (1734-1800) published a study of the motion of a sphere on an horizontal plane in the presence of Newtonian friction. His main result would be rediscovered independently by Gaspard Coriolis as part of his authoritative theoretical work on the topic: Théorie mathématique des effets du jeu de billard (1835). Johann Albrecht Euler, born in St. Petersburg 1732 was a Swiss-Russian astronomer and mathematician and he was the first child born to the great Swiss mathematician Leonhard Euler. ‎

‎(Berlin, Haude et Spener, 1753). 4to. No wrappers as issued in ""Memoires de l'Academie Royale des Sciences et Belles Lettres"". tome VII, pp. 305-330 + two engraved plates.‎

‎First printing of Euler's paper on how to raise water, which was a study written on the background of his - unsuccessful - garden-project in Frederick the Great's large complex of summer palaces, Sanssouci where Euler was asked to design the pumps to the many fountains. ""I wanted to make a fountain in my Garden"", Frederic the Great wrote to Voltaire on 25 January 1778. But the water-art project ended in a fiasco. The fountain design was supposed to be executed according to the latest knowledge in hydraulics and should even surpass Versailles with its splendor. ""Euler calculated the effort of the wheels for raising the water to a basin, from where it should fall down through canals, in order to form a fountain jet at Sans-Souci. My mill was constructed mathematically, and it could not raise one drop of water to a distance of fifty feet from the basin.""Since then the fiasco at Sanssouci stands out as an example for the gulf between theory and practice. And Leonhard Euler, the mathematical genius from Basel, became a target of mockery and malicious joy"". (Michael Eckert: Euler and the Fountains of Sanssouci).See Enetröm E202.‎

‎"In French. Short description: Euler Leonhard. Lettres a une princesse d'Allemagne sur divers sujets de physique et de philosophie. [Letters To a Princess of Germany on Various Subjects of Physics and Philosophy]. Volume 2. St. Petersburg Imperial Printing House 1768. Letters to a German Princess on Various Physical and Philosophical Matters occupy a special place in the scientific heritage of Leonhard Euler. The essay is written in an epistolary form unusual for Euler and is a presentation of the foundations of natural science and philosophy of that time in its interpretation; it bears a bright imprint of the author's personality his many years of searching and thinking about the nature of physical phenomena his ideas about the structure of the Universe about the philosophical and physical picture of the world. This very serious and complex scientific material is presented in the form of letters-conversations in which scientific rigor is combined with clarity and accessibility of presentation designed for an unprepared reader. The Letters were published anonymously but Euler's authorship was no secret to anyone. For the first time Letters were published in St. Petersburg in French and in Russian translation.

‎First printing of Eulers's importent paper in which he defended the wave-theory of light in opposition to the newtonian corpuscular hypothesis.Most of the scientists and philosophers of the 18th century defended the corpuscular theory of light, but Euler ""being impressed by the notion that the emission of particles would cause a diminuation in the mass of the radiating body, which was not observed, while the emission of waves involved no such consequence...he insisted strongly on the resamblance between light and sound" the whole of the space through which the heavenly bodies move is filled with a subtle matter, the aether, and light consists in vibrations of this aether 'light is the same thing as sound in air'....The chief novelty of Euler's writings on light is his explanation of the manner in which material bodies appear coloured when wieved with white light" and, in particular the way in which colours of thin plates are produced.""

The theories laid down here is also called Euler's second theory and it is the most interesting. It was of the greatest importtence as a basis for later developments.""He applied his mathematics to astronomy, working out the nature of some perturbations, being in this respect the precursor of Lagrange and Laplace. He began to replace the geometric methods of proof used by Galileo and Newton with the algebraic, a tendency carried to its conclusion by Lagrange. In particular he worked on lunar theory, that is, on the analysis of the exact motion of the moon, the complications of which have been the despair of astronomers and mathematicians since the time of Kepler. - Eneström: 398, 399, 400 a. 401.‎

‎First editions of Eulers three main papers on the theory of sounds in which he formulated the WAVE EQUATION for the propagation of sounds in the air. In the first paper Euler analyzes the forces that act on a slice of air that is in a disturbed state at y but was initially at x. The analysis is customary in the modern elementary works. In the second paper Euler gets a result that is equivalent to the general formula ofinversion for partial differentiations, noting in addition that cylindrical and spherical waves also follow it.""Euler, Lagrange, and others worked on the propagation of sound in air. Euler wrote on the subject of sound frequently from the time he was twenty years old (1727) and established this field as a branch of mathematical physics...Three fine and definitive papers were read to the Berlin Academy in 1759 (the papers offered here).

‎First printing of two Euler-papers in which he occupies himself with an unsolvable geometric problem and the physics of the different refrangibilities of light rays, a field Euler made important and original contributions to. Euler's wave theory of light, published in 1746, was based on an analogy between sound and light to a more and more mathematical elaboration on that notion. His wave theory degenerated, and it was not until Fresnel introduced transverse waves and an elaborate notion of interference that the wave theory again progressed. He was the second after Christian Huygens to proposed a wave theory of light, and thereby one of the earliest to argue against Newton's particle theory of light. His 1740s papers on optics helped ensure that the wave theory of light proposed by Christian Huygens would become the dominant mode of thought until the development of the quantum theory of light.See Eneström E220, E221.‎
