(Berlin, Haude et Spener, 1748). 4to. No wrappers as issued in "Memoires de l'Academie Royale des Sciences et Belles Lettres". tome II, 1746. Pp. 225-248. First apperance of Euler's mathematical treatment of the retrograde motions of the planets. He discusses the fact that planets observed from the earth exhibit a very irregular… motion. In general, they move from west to east along the ecliptic. At times however, the motion slows to a stop and the planet even appears to reverse direction and move from east to west. We call this retrograde motion. After some time the planet stops again and resumes its west to east journey. However, if we observe the planet from the stand point of an observer on the sun, this retrograde motion will not occur, and only a west to east path of the planet is seen. These facts Euler treats mathematically.

First appearance of this paper, in which Euler proves that given the static principle, he can derive the equilibrium conditions for a fluid, and f…rom these, he obtains the integrability conditions for a "Pfaffian" form in three variables. 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.

(Berlin, Haude et Spener, 1753). 4to. No wrappers, as issued in "Mémoires de l'Academie Royale des Sciences et Belles-Lettres", tome VII, Année 1751. Pp. 221-245 and pp. 246-254 a. 1 engraved plate. First editions. The first paper concerns the Argument over the principle of least action, relating to the famous controversy - and…one of the ugliest scientific controversies - between Koenig and Maupertuis. "In 1751 a sensational new argument began when S. König published some critical remarks on Maupertuis?s principle of least action (1744) and cited a letter of Leibniz in which the principle was, in König?s opinion, formulated more precisely. 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. The conflict grew critical when later in the same year Voltaire published his Diatribe du docteur Akakia, médecin du pape, defending König and making laughingstocks of both Maupertuis and Euler."(DSB) - Enestrom No. 199.The second paper - Enestrom No. 200.

First edition. In this importent paper Euler perfection Segner's hydraulic turbine, giving the theory of hydraulic turbines created in acco…rdence with the principle of action and reaction."In this work, Euler gives a complete hydraulic analysis, an early example of the theory of relative motion. He also shows that very high speeds are necessary for good efficiency. He argues that "by means of fixed conducting tubes, adjust the incoming velocity of the water so that the speed of efflux relative to the rotor is zero" in this way, the theorietical efficiency will be 100% at the desired speed of operation."(Truesdell).Enestroem: 179.

First printing of 4 importent ea…rly 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.

Euler's goal in the first paper is to show that certain phenomena that resulted from the ecl…ipse 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.

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.
