‎The highly important first Latin translation of Leibnitz' seminal ""The Monadology"" - his main philosophical work and the work that stands as the epitomization of anti-materialism - which was not published in the original French until 1814, and which only appeared in a German translation (exceedingly scarce) in 1720 and in a Latin translation, by Christian Wolff, in 1721, as it is here. Up until then, Leibnitz' key philosophical text had only circulated in manuscript form (written in 1714). - Here sold together with Wolff's anonymously written review of (the German version of the) ""Monadology"", which had great impact upon the reception of the seminal philosophical text that is the ""Monadology"".""Until the XXth century, criticism about Leibniz's ""Principles of Nature and Grace"" and ""Monadology"" has been characterised by a number of mistakes and misunderstandings, which have roots in the circumstances surrounding the genesis of these manuscripts. As a consequence, erroneous information about these texts was included in an anonymous review, published in 1721 in the ""Acta eruditorum"" of Leipzig. Research on primary sources proves that the author of this review (who was in fact the author of the latin translation of the Monadology, published immediately afterwards) was Christian Wolff, who was in possession of a copy of Leibniz's manuscript as early as 1717. Wolff's initiative of translating the Monadology can be seen as part of a cultural strategy aiming to prevent any idealistic interpretation of Leibniz's monadological thought. From this point of view, to consider the theory of pre-established harmony as based on a system of strictly dualistic metaphysics was an essential element of Wolff's philosophical strategy.""(Antonio Lamarra: Contexte génétique et première reception de la ""Monadologie"". Leibniz, Wolff et la doctrine de l'harmonie préétablie""). During his last stay in Vienna from 1712 to September 1714, Leibniz wrote two short texts, which were meant as concise expositions of his philosophy, namely the ""Principes de la Nature et de la Grace fondés en raison"" (written as a letter to Prince Eugene of Savoy) and the work we now know as the ""Monadology"" (which he had been asked to write by Nicolas Redmond, Duke of Orleons) - the latter being the work that established Leibnitz' fame as a philosopher and which has gone down in history as, not only as one of the most important philosophical texts of the 18th century, but also, arguably the most important work of immaterialism. After his death ""Principes de la Nature et de la Grace fondés en raison"" appeared in French in the Netherlands. Without having seen this publication, Christian Wolff and collaborators had assumed that it contained the French original of the ""Monadology"" as well, although this in fact remained unpublished until 1840. Thus it happened that Leibnitz' key philosophical text, which came to be known as ""The Monadology"", was printed in German and Latin ab. 120 years before it appeared in the original French. The German translation appeared in 1720 as ""Lehrsätze über die Monadologie"" and the following year the Latin translation appeared, in Acta Eruditorum, as ""Principia philosophiae"". Three manuscript versions of the text exist: the first written by Leibniz and overcharged with corrections and two further emended copies with some corrections appearing in one but not the other. ""Leibniz was one of the last ""universal men"" of the type which the Italian Renaissance had ideally postulated: philosopher, historian, mathematician, scientist, lawyer, librarian, and diplomat. In all these fields either all his actual achievements or his seminal suggestions have become part and parcel of European thought. Although trained for the law, mathematics was his favourite subject. Independently of Newton he worked out the infinitesimal calculus, introduced a number of mathematical symbols now in general use, and constructed an early calculating machine, the ancestor of our computers. Mathematical conceptions also determine his philosophy. In it, Leibniz tried to combine physics and metaphysics and to reconcile philosophy and theology. The ""essay on a Theodicy"" is the only larger philosophical work published by himself"" but his fame as a philosopher rests on his ""Theory of Monads"". The original French text of this was published for the first time in 1840"" but it had circulated in manuscript in its initial form of a letter addressed to Prince Eugene of Savoy (1714) and it was printed in German (1720) and Latin (1721) translations. Leibniz proclaimed a ""pre-established harmony"" of the universe which he explained as composed of hierarchically ordered ""monads"", i.e. the ultimate substances of mind as well as matter. This concept clearly reflects the ideal of the properly organized absolutist state of the baroque period and derives partly from the ""idées simples"" of Descartes whom Leibniz greatly admired. A generation later, Voltaire ridiculed the ""pre-established harmony"" in ""Candide"""" but modern nuclear science has vindicated Leibniz's basic ideas, albeit from different presuppositions."" (Printing and the Mind of Man, pp. 105-6). The ""Monadology"" is an extremely condense work that consists of 90 (in this Latin version, 93) numbered sections/paragraphs, which outline a metaphysics of a single substance. The Monadology ends the dualistic mind-body-problem of Descartes and offers a new solution to the question of the interaction between mind and matter, by explaining the pre-established harmony and the synchronous (not causal) relationship between the realm of final causes and that of efficient causes. Leibniz' groundbreaking work came to profoundly influence not only 18th century thought, but also much later philosophy and logic. For this we have to thank Christian Wolff, the translator of the ""Monadology"" into Latin and the first reviewer of the work. It is through Wolff and his elaboration of the development of Leibniz' speculative and metaphysical views that Leibniz becomes a recognized figure of importance, particularly in Germany from the 1720'ies onwards, where Wolff's writings were standardly studied. ""Notably, Wolff's Leibnizianism made a deep impact on Kant, in whose ""Critique of Pure Reason"" (1781) Leibniz himself came to figure as one of the main targets of Kant's anti-metaphysical programme. In particular, Kant saw Leibniz as pretending to ""a priori"" knowledge of the world as it is in itself and presented his own claim that the only knowledge we can have is of the world as it appears in our experience as sharply opposed to the Leibnizian vision. [...] today shows that his thought has survived even the extreme empiricism of the Vienna Circle in the 1930s, which would have viewed its principal doctrines as unverifiable and hence utterly meaningless. Although not in evidence in the ""Monadology"" itself, one of Leibniz' preoccupations was with the philosophy of logic and language, and the twentieth-century's concern for those topics has discovered in what he had to say about them a treasure house of good sense and wisdom which can be detached from the less appealing of his metaphysical speculations. Then, more recent writers who have been interested in the metaphysics of possibility and necessity have found inspiration in the Leibnizian image of possible worlds, and that too has helped keep his name alive for us."" (Savile, ""Leibniz and the Monadology"", pp. 6-7). ""The long span of Leibniz' intellectual life and his early involvement with philosophy made for engagement with a wide variety of philosophical traditions and issues. Early studies at home exposed him to the thought of the Scholastics"" during his university years he was something of a materialist, influenced by the atomism of Bacon and Gassendi. In his mid-20s and early 30s, becoming disenchanted with the intellectual prospects for materialist thought, he turned towards the sort of immaterialism that came to shape his mature thinking after the decade between 1675 and 1685 when he was more narrowly concerned with mathematics than philosophy. It is this anti-materialism that is epitomized in the ""Monadology"" itself...Although Leibniz produced a prodigious quantity of philosophical writing very little of it was published in his lifetime"" indeed, very little was intended for publication. For the most part..., his philosophical thoughts were prepared for individual scholars he had met, or with whom he corresponded, and were never presented as a worked-out system... it was not until the last period of his life that he found the time and the impetus to set down the whole, which he did in two condensed papers written in French during a visit to Vienna.The more popular and less taxing of these was the ""Principles of Nature and Grace Founded on Reason"", which he prepared for Prince Eugène of Savoy, and the second, which he had been asked to write by the councellor of the Duke of Orleans, Nicolas Remond, but never sent off, was the ""Principles of Philosophy"" or, as he called it ""Elucidation Concerning Monads"" ... The title by which that work is known today, ""Monadology"", was not one that Leibniz ever gave it, but was invented by the work's first editor, Henrich Kohler, who published it in a German translation under that title in 1720."" (Savile, ""Leibniz and the Monadology"", pp. 3-4). ""Gottfried Wilhelm Leibniz (1646-1716) was one of the great thinkers of the seventeenth and eighteenth centuries and is known as the last ""universal genius"". He made deep and important contributions to the fields of metaphysics, epistemology, logic, philosophy of religion, as well as mathematics, physics, geology, jurisprudence, and history. Even the eighteenth-century French atheist and materialist Denis Diderot, whose views were very often at odds with those of Leibniz, could not help being awed by his achievement, writing in his entry on Leibniz in the Encyclopedia, ""Perhaps never has a man read as much, studied as much, meditated more, and written more than Leibniz... What he has composed on the world, God, nature, and the soul is of the most sublime eloquence. If his ideas had been expressed with the flair of Plato, the philosopher of Leipzig would cede nothing to the philosopher of Athens."" (""Oeuvres complètes"", vol. 7, p. 709) Indeed, Diderot was almost moved to despair in this piece: ""When one compares the talents one has with those of a Leibniz, one is tempted to throw away one's books and go die quietly in the dark of some forgotten corner."" (""Oeuvres complètes"", vol. 7, p. 678) More than a century later, Gottlob Frege, who fortunately did not cast his books away in despair, expressed similar admiration, declaring that ""in his writings, Leibniz threw out such a profusion of seeds of ideas that in this respect he is virtually in a class of his own."" (""Boole's logical Calculus and the Concept-script"" in ""Posthumous Writings"", p. 9)."" (SEP).Ravier: 357(PMM 177b - being the Latin translation)‎

Notes du traducteur - Le développement du calcul infinitésimal est attribué à Archimède, Fermat, Leibniz et Newton. Cependant, lorsque le calcul infinitésimal a été initialement développé, une controverse fut soulevée sur qui en avait la paternité entre Leibniz et Newton, occultant auprès du grand public l'apport de Fermat. L'algorithme du passage à la limite pour calculer la tangente à une courbe est en effet une invention de Fermat (méthode des maxima et minima) en 1636 et était public dès 1667, car rapporté par Huygens à l'Académie des sciences. Les évolutions ultérieures, de Leibniz et Newton (qui étaient en rapport avec Huygens), portent sur les notations. La contribution majeure de Leibniz fut sans conteste son système de notation. La controverse fut cependant malheureuse car elle a divisé pendant de nombreuses années les mathématiciens anglophones et ceux du reste de l'Europe. Cela a retardé le progrès de l'analyse (mathématiques basées sur le calcul infinitésimal) en Grande-Bretagne pendant longtemps. La terminologie et les notations de Newton étaient clairement moins flexibles que celles de Leibniz. Elles furent malgré tout conservées jusqu'au début du xixe siècle lorsque le travail de l'Analytical Society introduisit avec succès la notation de Leibniz en Grande-Bretagne. Barrow, Descartes, Huygens et Wallis contribuèrent également dans une moindre mesure au développement du calcul infinitésimal.

‎First printing of these extremely important papers, in which Leibniz claimed that he independently of Newton had discovered the principal propositions of his ""Principia"" and which present us with Leibniz's fundamental physico-mathematical theory, his dynamics, his concepts of force, space and time. The ""Tentamen..."" constitutes Leibniz's response to Newton's theories about the motion of the celestial bodies. Leibniz can be said to have anticipated the modern mathematical principle of relativity, as it is his idea of individual co-ordinate systems and his practical rejection of the Galilean co-ordinate system that Newton adopted. Leibniz opposes Newton's ideas of attractions (gravitational forces) and calls them ""occult qualities"". The task of the ""Tentamen..."" was to attain a theory mathematically equivalent to Newton's in accounting for planetary motion and especially for the inverse-square law of Kepler's laws, but physically sound and capable of explaining the causes of phenomena.Newton attacked Leibniz's claim of priority in his anonymously published paper ""Commercium epistolicum"" (Phil. Transactions 1714), and states that ""in those tracts the principal propositions of that book are composed in a new manner, and claimed by Mr. Leibniz as if he had found them himself before the publishing of the said book. But Mr. Leibniz cannot be a witness in his own cause. It lies upon him either to prove that he had found them before mr. Newton, or to quit his claim."" The features of Leibniz's mathematical representation of motion as put forward in ""Tentamen..."" are, (see D.B. Meli: Equivalence and Priority. Newton versus Leibniz. pp. 90-91):- Empty space does not exist. The world is filled with a variety of fluids which are responsible for physical actions, including gravity.- Living force and its conservation are the fundamental notion and principle respectively, in the investigation of nature, however, they do not figure prominently in the study of planetary motion.- Finite and infinitesimal variables are regularly employed in the study of motion and of other physical phenomena. Living force and velocity are finite" solicitation and conatus are infinitesimal.- Accelerated motion, whether rectilinear or curvilinear, is represented as a series of infinitesimal uniform rectilinear motions interrupted by impulses. I call this 'polygonal representation'. Usually the polygon is chosen in such a way that each side is traversed in an equal element of time dt. In polygonal representations accelerations are reduced to a macroscopic phenomenon.- Propositions are often used to safeguard dimensional homogeneity. Constant factors - such as numerical factors, mass, and the element of time - are usually ignored in the calculations.Denys Papin's papers:1.

Bien qu'il soit aujourd'hui connu pour sa métaphysique et sa théorie de l'optimisme, Leibniz s'est imposé comme une des principales figures de la révolution scientifique au même titre que Galilée, Descartes, Huygens, Hooke et Newton. Leibniz est devenu très tôt mécaniste, vers 1661, alors qu'il étudiait à Leipzig, comme il le relate dans une lettre à Nicolas Rémond. Cependant, une différence profonde le sépare d'Isaac Newton : si Newton considère que « la physique se garde de la métaphysique » et cherche à prévoir les phénomènes par sa physique, Leibniz cherche à découvrir l'essence cachée des choses et du monde, sans chercher à obtenir des calculs précis à propos de phénomènes quelconques. D'ailleurs jamais il n'employa son calcul infinitésimal pour expliquer les lois de la nature. Il en est venu ainsi à reprocher à René Descartes et à Newton de ne pas savoir se passer d'un Deus ex machina (une raison divine cachée) dans leurs physiques, car celles-ci n'expliquaient pas tout ce qui est, ce qui est possible et ce qui n'est pas. Leibniz a inventé le concept d'énergie cinétique, sous le nom de « force vive ». Il s'oppose à l'idée de Descartes que la quantité mv (qu'on appelait à cette époque force motrice ou quantité de mouvement) se conservait dans les chocs, indépendamment des directions du mouvement. - Le principe de moindre action a été découvert en 1740 par Maupertuis. En 1751, Samuel König affirma avoir une lettre de Leibniz, datée de 1707, dans laquelle il énonçait ce même principe, donc bien avant Maupertuis. L'Académie de Berlin chargea Leonhard Euler de se pencher sur le problème de l'authenticité de cette lettre. Euler fit un rapport, en 1752, où il conclut à un faux : König aurait inventé l'existence de cette lettre de Leibniz. Ce qui n'empêche pas Leibniz d'avoir, en optique, avancé un énoncé (sans formalisme mathématique) proche du principe de Fermat, vers 1682. Dans ses Philosophiae naturalis principia mathematica, Isaac Newton conçoit l'espace et le temps comme des choses absolues. Dans sa correspondance avec Samuel Clarke, qui se fait l'avocat des idées de Newton, Leibniz réfute ces idées et propose un système alternatif. Selon lui, l'espace et le temps ne sont pas des choses dans lesquelles se situent les objets, mais un système de relations entre ces objets. L'espace et le temps sont des « êtres de raison », c'est-à-dire des abstractions à partir des relations entre objets.

‎All papers first apperance. All 5 of extreme importence in the development of the Calculus. Leibniz' 2 papers on the catenary curve (paper 1-2 offered here) was written at the instigation of Jacques Bernoulli. Following the example of Blaise Pascal, who had initiated, in 1658, a contest for the construction of the cycloid, Leibniz also provoked the geometers of his time, by challenging them to submit, at the fixed date of mid-1691, their geometric method for the construction of the catenary curve. Leibniz later provided the answer, followed by Johann Bernoulli and Huygens.'These two papers are a historical account of the origin of the study of this transcendental curve, and, at the same time, the first physical-geometric construction showing the species-relationship between the catenary and the logarithmic curves, as two companion curves" one arithmetic, the other geometric. All of the differentials of the catenary curve, are arithmetic means of corresponding differentials of the logarithmic curve" and, all of the differentials of the logarithmic curve, are geometric means of the catenary.'""The Catenary is the form of a hanging fully flexible rope or chain (the name comes from ""catena"", which means 'chain'), suspended on two points. The interest in this curve originated with Galileo, who thought that is was a parabola. Young Christiaan Huygens proved in 1646 that this cannot be the case. What the actual form was remained an open question till 1691, when Leibniz, Johann Bernoulli and the then much older Huygens sent solutions to the problem to the ""Acta"" (Jakob Bernoulli, 1690, Johann Bernoulli 1691, Huygens 1691 and Leibniz 1691), - these 4 1691-papers offered here - in which the previous year Jakob Bernoulli had challenged mathematicians to solve it. As published, the solutions did not reveal the methods, but through later publications of manuscripts these methods have been known. Huygens applied with great ( paper 4) virtuosity the by then classical methods of 17th century infinitesimal mathematics, and he needed all his ingenuity to reach a satisfactory solution. Leibniz ( the papers 1-2) and Bernoulli (paper 3), applying the new Calculus, found the solutions in a much direct way. In fact, the catenary was a test-case between the old and the new style in the study of curves, and only because the champion of the old style was a giant like Huygens, the test-case can formally be considered as ending in a draw."" (Grattan-Guiness in ""From the Calculus to Set Theory, 1630-1910."").The paper by JACOB BERNOULLI ( no. 5 offered here) is a milestone papers as it marks the invention of the ""SYSTEM OF POLAR COORDINATES"" with points located by reference to a fixed point and a line through that point. Although newton had earlier also devised such a coordinate system (in 1671), his work was not known, so that the credit for the discovery generally goes to Bernoulli.

‎First printing of a series of influential papers by Leibniz, Jacob Bernoulli and Johann Bernoulli.First publication of Jakob Bernoulli's famous and influential ""Bernoulli Equation"". In ""Notatiuncula Constructiones Lineae"" Bernoulli proposed a solution to non linear equations which today is one of the most common used solutions of the general fluid. Bernoulli equations are significant because they are nonlinear differential equations with known exact solutions. In the ""Specimen dynamicum"" Leibniz presents a conception of body and force which distinct between primitive and derivative forces and between active and passive forces. This article is regarded as being the clearest exposition of Leibniz' dynamics. (DSB VII, 151b).""The first attempt at a detailed account of the dynamics was a long dialogue, the ""Phoranomus seu de potentia et legibus naturae,"" written in July 1689 while Leibniz was in Rome. This was quickly followed be the composition of the massive Dynamica de potential et legibus naturae corporeae (1689-90) [...]. Though it was written with the intention of publication, and though Leibniz work at publishing it, he never considered it entirely finished and it remained unpublished during his lifetime.The later [...] he finally revealed some of the metaphysical foundations of the project in an essay [the present paper]."" (Garber, Daniel. Leibniz: body, substance, monad. 2009. 132 p.)""Its title suggests a summary of or a selection from the earlier work [...]. However, it actually contains something in a way rather more interesting: a careful exposition of the metaphysical foundations of the new science, something that is hard to find in the old Dynamica or any of the more Technical pieces."" (Garber, Daniel. Leibniz: Body, Substance, Monad. 2009. 133 p.)‎

‎First printing of the famous 1696-edition of Acta Eruditorum in which Johann Bernoulli published a challenge to the best mathematicians:""Let two points A and B be given in a vertical plane. To find the curve that a point M, moving on a path AMB , must follow such that, starting from A, it reaches B in the shortest time under its own gravity.""Johann adds that this curve is not a straight line, but a curve well known to geometers, and that he will indicate that curve, if nobody would do so that year. Later that year Johann corresponded directly with Leibniz regarding his challenge. Leibniz solved the problem the same day he received notice of it, and almost correctly predicted a total of only five solutions: from the two Bernoullis, himself, L'Hospital, and Newton. Leibniz was convinced that the problem could only be solved by a mathematician who mastered the new field of calculus. (Galileo had formulated and given an incorrect solution to the problem in his Dialogo). But by the end of the year Johann had still not received any other solutions. However, Leibniz convinced Johann that he should extend the deadline to Easter and that he should republish the problem. Johann now had copies of the problem sent to Journal des sçavans, the Philosophical Transactions, and directly to Newton. Earlier that year Johann had accused Newton for having filched from Leibniz' papers. Manifestly, both Johann and Leibniz interpreted the silence from June to December as a demonstration that the problem had baffled Newton. They intended now to demonstrate their superiority publicly. But Newton sent a letter dated Jan. 30 1697 to Charles Montague, then president of the Royal Society, in which he gave his solution and mentioned that he had solved it the same day that he received it. Montague had Newton's solution published anonymously in the Philosophical Transactions. However, when Bernoulli saw this solution he realized from the authority which it displayed that it could only have come from Newton (Bernoulli later remarked that he 'recognized the lion by its claw'). The present volume contains the following articles of interest:Jakob Bernoulli: 1, Observatiuncula ad ea quaenupero mense novembri de Dimensionibus Curvarum leguntur.2, Constructio Generalis omnium Curvarum transcendentium ope simplicioris Tractoriae et Logarithmicae.3, Problema Beaunianum universalius conceptum.4, Complanatio Superficierum Conoidicarum et Sphaeroidicarum.Johann Bernoulli5, Demonstratio Analyticea et Syntetica fuae Constructionis Curvae Beaunianae.6, Tetragonismus universalis Figurarum Curvilinearum per Construitionem Geometricam continuo appropinquantem.Tschirnhaus7, Intimatio singularis novaeque emendationis Artis Vitriariae.8, Responsio ad Observationes Dnn.

Leibniz discovered, when he read Tschirnhaus' papers, that Tschirnhaus had here published results showing similarity with Leibniz's invention of the calculus as he had confided to Tschirnhaus earlier, during their Parisian stay, and this without references to Leibniz.The second issue contains an original paper by LEIBNIZ: ""Meditatio Juridico-Mathematica de Interusurio simplice"".

En février 1689, il publie le Tentamen de motuum coelestium causis (« Essai sur les causes des mouvements célestes »), où il tente d'expliquer le mouvement des planètes à l'aide de la théorie des vortex de René Descartes, pour fournir une alternative à la théorie newtonienne qui recourt aux « force à distance » - Dans ses Philosophiae naturalis principia mathematica, Isaac Newton conçoit l'espace et le temps comme des choses absolues. Dans sa correspondance avec Samuel Clarke, qui se fait l'avocat des idées de Newton, Leibniz réfute ces idées et propose un système alternatif. Selon lui, l'espace et le temps ne sont pas des choses dans lesquelles se situent les objets, mais un système de relations entre ces objets. L'espace et le temps sont des « êtres de raison », c'est-à-dire des abstractions à partir des relations entre objets.

‎Extremely scarce first Latin edition of Leibniz's hugely influential work ""Essais de Theodicée sur la Bonté de Dieu, la Liberté de L'Homme, et L'Origine du Mal"" (1710). It is his importent treatise on the goodnes of God, the free will of man and the causes of evil in the world, The principal subject of the work being the problem of liberty and free will. It is the only larger philosophical work published by Leibnitz himself.The ""Théodicée"" was a response to skeptical Pierre Bayle, who wrote in his work Dictionnaire Historique et Critique that, after rejecting three attempts to solve it, he saw no rational solution to the problem of evil.The work was composed at the instigation of Sophia Charlotte, with whom Leibniz had conversed concerning the views of Bayle. In response to a request from Prince Eugene for an abstract of the Théodicée, Leibniz in 1714 wrote the ""Principes de la nature et de la grâce fondées en raison and the Monadologie"".It is often the case, that this Latin edition is followed by the small work ""Causa Dei Asserta per Justitiam Ejus...""

‎First printing of one of Leibniz's latest publications in which he proposed an interpretation of infinitesimals by a comparison of bodies of different extensions. The paper is a response to to a problem raised by French philosopher and mathematician Antoine Arnauld, who wrote an important philosophical work known as ""The Logic of Port-Royal"" from 1662 and ""Geometry"", 1667. In the book he includes an example of symbolic rules that he considers to be against our basic intuitions on magnitudes and proportions. His reasoning goes as follows ""Suppose we have two numbers, a larger and a smaller one. The proportion of the larger to the smaller one should evidently be larger than the proportion of the smaller to the larger one. But if we use 1 as the larger number and - 1 as the smaller one this would lead to (1/-1) > (-1/1) which is against the rules of algebra"". (Heeffer, The Methodological Relevance of the History of Mathematics for Mathematics Education, 1992).Leibniz saw this as a genuine mathematical problem but argued that the division should be performed as a symbolic calculation. ""Following Leibniz, the infinite appeared in two forms as the (i) Contiuous infinite and (ii) the discrete infinite. The status of the differentials is closely related to the status of the infinite. [...] As a consequence, there is no clear and consistence distinction between continua of different kind related to (i) geometry and to (ii) mechanics. [...] Leinbiz did neither consequently argue mathematically or arithmetically nor consequently geometrically, phenomenologically and mechanically. [But] The correlation between mathematics and physics is as impressive as possible. (Suisky, Euler as physicist, 2009, p. 89-90).The volume also contains:Bernoulli, Johann.

‎First printing of the famous Libnitz-issue of Acta Eruditorum published a year after the death of Leibnitz, including the renowned obituary by the German philosopher Christian Wolff. In 1706, Leibniz recommended Wolff for the Professorship at Halle, the post Wolff held for seventeen years until his dismissal, and in 1711, Leibniz sponsored Wolff's membership to the Berlin Academy. It is also mentioned that during the year of Leibniz's death in 1716, Leibniz visited Wolff in Halle when returning to Hanover from Vienna. To honor Leibnitz memory Wolff undertook the project of writing ELOGIUM GODOFREDI GUILIEMI LEIBNITII, a treatise of the life of Leibnitz. As early as 1679 George I, acting as Leibnitz patron, directed him to write the history of the house of Brunswick. Immediately after he began arranging material he had collected. The work was, however, only the preparatory steps when Leibnitz died in 1716 and the work was never published. The present paper, NOTITIA DE HISTORIA BRUNSUICENSI, is the only part of the work, which could have become a opus magnum with historiography, that has ever been published. The volume also contains:Goldbach, Christian. Temperamentum Musicum Universale. Pp. 114-15.And many other papers by influential contemporary mathematicians, philosophers and historians.‎

‎All papers first appearance, dealing with, and clarifying the problems and the new applications of Leibniz' inventions of the differential- and integral calculus.In the papers Leibniz shows how to reduce linear first order ordinary differential equations to quadratures. I the other paper he gives a general method of finding the envelope of a family of curves, which helped to spread the theory of plane curves.In the groundbreaking paper offered here, Jakob Bernoulli introduces THE LEMNISCATE, a symmetric self-intersecting curve resembling a figure eight and defined by the condition that the product of the distance of anay point on the curve from two fixed points is (d/2)2, where d is the distance between the fixed points.""Jacob Bernoulli was fascinated by curves and the calculus, and one curve bears his name - the ""lemniscate of Bernoulli"", given by the polar equation r2=a cos 2""0"". The curve was described in the Acta Eruditorum of 1694 as resembling a figure eight or a knotted ribbon (lemniscus). However the curve that most caught his fancy was the logarithmic spiral....he swowed that it had several strioking properties not noted before...it is easy to appreciate the feeling that led Bernoulli to request that the ""spira mirabils"" be engraved on his tombstone together with the inscription ""Eadem mutata resurgo"" (Though changed, I arise again the same).""
