"Papin behauptete nun in Mechanicorum de viribus motricibus sententia Acta erud. Jan. 1691 S.6-13 dass ein Effekt weder durch den zurückgelegten Weg noch durch die Zeitdauer der Bewegung sondern allein durch den zu überwindenden Widerstand gemessen wird. Als Konsequenz daraus verneinte er u. a. die Möglichkeit einer vollständigen Übertragbarkeit der Kraft. In seinem folgenden Beitrag De legibus naturae et vera aestimatione virium motricium contra Cartesianos Acta erud. Sept. 1691 S. 439-447 versuchte Leibniz Papins Argument der Nichtübertragbarkeit der gesamten Kraft eines Körpers auf einen anderen zu entkräften. Durch ein Gedankenexperiment erbrachte Leibniz den Nachweis einer vollständigen Kraftübertragung von einem Körper mit größerer auf einen mit kleinerer Masse. Nach Leibniz lagen gleiche Kräfte dann vor wenn eine gleiche Anzahl von elastischen Federn mit gleicher Spannkraft in den gleichen Spannungszustand elastischen Federn mit gleicher Spannkraft in den gleichen Spannungszustand überführt werden konnten. Zur Bestimmung des Kraftmaßes dürften nur solche Effekte herangezogen werden bei denen die Kraft die aufgenommen wurde auch wieder abgegeben werden könne wie etwa bei gespannten Federn oder bei erstiegenen Fallhohen im Schwerefeld."

Mathematik Statistik und Versicherung - "Auch selbst hat sich Gottfried Wilhelm Leibniz 1646-1716 eingehend mit Fragen der Versicherungsmathematik insbesondere des Barwertes des Gesundheitswesens und der Statistik befaßt. Er forderte die jährliche Veröffentlichung von Geburts- und Sterbelisten im Interesse des Ausbaus der Personenversicherung. Außerdem dachte er an eine "Reservekasse als Nothpfennig für Witwen und Waisen" wofür jedem Beamten von seiner Besoldung jeweils ein bestimmter Betrag abgezogen werden sollte um die Hinterbliebenen vor dem äußersten Ruin und Armut nach dem Tode des Ernährers zu schützen. Dem weiteren Fortschritt des Versicherungswesens kam schließlich außer der Erfindung seiner Rechenmaschine die Entwicklung der Zinseszinsrechnung zu statten die er 1683 in der damaligen Gelehrtenzeitschrift "Acta Eruditorum" veröffentlichte." Peter Koch Geschichte der Versicherungswissenschaft in Deutschland: Aus Anlass seiner . 1998 pp.61-62 "A detailed legal and economic apologia for the principle of discounting with compound interest is to be found for the first time in the works of Gottfried Wilhelm Leibniz in 1682. He shows that the calculation of capital values follows from three self-evident legal maxims for the premature redemption of a debt. Compound interest is a result of the reinvestment of money released from an investment. And that is why the discussion on whether compound interest is usury was bound to lead to the discovery of the reinvestment premises in investment accounting procedures."

1682600581682. Acta Eruditorum 1682/ 2. - Leipzig Grossium & Gleditsch Februar 1682 4° pp.33-56 1 Kupferstichtafel feine Broschur. First Edition! This was Leibniz first article published in Acta Eruditorum; He deals with mensuration and describes the Leibniz series 1-1/31/5-1/7.=pi/4. Gottfried Wilhelm Leibniz's 1646-1716 Hannover appointment in the Hanoverian service gave him more time for his favourite pursuits. He used to assert that as the first-fruit of his increased leisure he invented the differential and integral calculus in 1674 but the earliest traces of the use of it in his extant note-books do not occur till 1675 and it was not till 1677 that we find it developed into a consistent system; it was not published till 1684. Most of his mathematical papers were produced within the ten years from 1682 to 1692 and many of them in a journal called the Acta Eruditorum founded by himself and Otto Mencke in 1682 which had a wide circulation on the continent. He was one of the true geniuses of modern history. Although his contributions to the development of differential calculus remain his greatest legacy his definition of identity and his work in establishing a formal notation for all mathematics provided the foundation for others like Peano nearly two hundred years later.

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."

First printing of these extremely important papers in which Gottfried Wilhelm Leibniz 1646-1716 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. 1. : De Lineis Opticis et alia; Excerpta ex literis ad pp.36-38 Tab.

IV Fig. 3. 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 -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. -cf. D.B. Meli: Equivalence and Priority. Newton versus Leibniz. pp. 90-91.

Entire volume: 2 603 1 pp. plates. <br/><br/><em>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'.

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.

16962447Leipzig: Gross & Fritsch 1696. First edition. vellum marbled boards. Very Good. FIRST PRINTINGS OF THE PAPERS DOCUMENTING THE PROPOSAL AND SOLUTION OF THE "BRACHISTOCHRONE PROBLEM" ONE OF THE MOST FAMOUS MATHEMATICAL CHALLENGES AND ONE OF THE EARLIEST PROBLEMS POSED IN THE CALCULATION OF VARIATIONS. The challenge of the brachistochrone "began in June of 1696 when Johann Bernoulli published a challenge problem in Leibniz's journal Acta Eruditorum. Obviously a legacy of public challenge remained from the days of Fior and Tartaglia. Although contests were now conducted in the sedate pages of scholarly journals they retained their power to make or break reputations as Johann himself observed:<br /> <br /> '. it is known with certainty that there is scarcely anything which more greatly excites noble and ingenious spirits to labors which lead to the increase of knowledge than to propose difficult and at the same time useful problems through the solution of which as by no other means they may attain to fame and build for themselves eternal monuments among posterity.'<br /> <br /> "Johann's particular challenge was a good one. He imagined points A and B at different heights above the ground and not lying one directly above the other. There is certainly an infinitude of different curves connecting these two points from a straight line to an arc of a circle to any number of other wavy undulating paths. Now imagine a ball rolling from A down to B along such a curve. The time it take to complete the trip depends of course on the curve's shape. Bernoulli challenged the mathematical world to find that one particular curve AMB along which the ball will roll the shortest time. He called this curve the 'brachistochrone' from the Greek words for 'shortest' and 'time'.<br /> <br /> "An obvious first guess is to take AMB as the straight line joining A and B. But Johann cautioned against this simplistic approach:<br /> <br /> '. to forestall hasty judgment although the straight line AB is indeed the shortest between the points A and B it nevertheless is not the path traversed in the shortest time. However the curve AMB whose name I shall give if no one else discovered it before the end of this year is one well-known to geometers.'<br /> <br /> "Johann gave the mathematical world until January 1 1697 to come up with a solution. However when his deadline arrived he had received but one solution from the 'celebrated Leibniz' who:<br /> <br /> 'has courteously asked me to extend the time limit to next Easter in order than in the interim the problem might be made public . that no one might have cause to complain of the shortness of the time allotted. I have not only agreed to this commendable request but I have decided to announce myself the prolongation and shall now see who attacks this excellent and difficult question and after so long a time finally masters it.'"<br /> <br /> At this point Johann and others were surprised and perhaps a little delighted that they had not received a solution from their English rival Sir Isaac Newton. Wondering if Newton has not noticed the challenge Johann sent Newton directly a personal letter outlining the problem. When Newton received the letter he did not disappoint. As Newton's niece Catherine Conduitt explained:<br /> <br /> "When the problem in 1697 was sent by Bernoulli - Sir I.N. was in the midst of the hurry of the great recoinage and did not come home till four from the Tower very much tired but did not sleep till he had solved it which was by four in the morning."<br /> <br /> "Even late in life and tired from a hectic day's work Isaac Newton triumphed where most of Europe had failed! It was a remarkable display of the powers of the great British genius. He had clearly felt his reputation and honor were on the line; after all both Bernoulli and Leibniz were waiting in the wings to publish their own solutions. So Newton rose to the occasion and solved the problem in a matter of hours. Somewhat exasperated he is reported at one point to have said 'I do not love . to be . teezed by foreigners about Mathematical things.'<br /> <br /> "Back in Europe as Easter neared a few solutions came into the hands of Johann Bernoulli. The curve that everyone was seeking - one that 'is well-known to geometers' - was none other than an upside-down cycloid. This important curve was studied by Pascal and Huygens but neither of these mathematicians had realized that it would also serve as the curve of quickest descent. Johann wrote with characteristic hyperbole '. you will be petrified with astonishment when I say that precisely this cycloid . of Huygens is our required brachistochrone.'<br /> <br /> "On Easter the challenge period had expired. All together Johann had received five solutions. There was his own and the one from Leibniz. His brother Jakob came through perhaps to Johann's dismay with a third and the Marquis de l'Hospital added a fourth. Finally there was a submission bearing an English postmark. Opening it Johann found the solution correct although anonymous. He clearly had met his match in the person of Isaac Newton. Although unsigned the solution bore the unmistakable signs of supreme genius.<br /> <br /> "There is a legend - probably of dubious authenticity but nonetheless of great charm - that Johann partially chastened partially in awe put down the unsigned document and knowingly remarked 'I recognize the lion by his claw.'"

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.
