De la Situation la plus avantageuse des Planetes pour Découvrir les Irrégularités de leurs Mouvemens. (+ Kies:) Sur les Eclipses des Etoileas fixes par la Lune. (+ Cassini de Thury:) Memoire, dans lequel on examiné, si l'on peut esperer la meme Pre...
(Berlin, Haude et Spener, 1751). 4to. No wrappers, as issued in ""Mémoires de l'Academie Royale des Sciences et Belles-Lettres"", tome V, Année 1749, pp. 339-372, 1 folded geometrical plate (to the first paper) and 3 fine double-page folded engraved plates showing the quadrant.
Kies was one of the first to propagate Newton's discoveries in Germany, and dedicated two of his works to the Englishman. The crater Kies on the Moon is named after him.The paper on the instrument describes and depicts the large quadrant in the Berlin observatory invented by Hadley (described in Transactions of the Royal Society in 1732).""From 1742 to 1754, at the recommendation of the mathematician Leonhard Euler, he (Kies) was made professor of mathematics at Berlin's Academy of Sciences and astronomer at its observatory. His reports from this time include De la Situation la plus avantageuse des planètes pour découvrir les irrégularités de leurs mouvemens, Sur les Éclipses des étoiles fixes par la lune, and Description d'un instrument qui se trouve .""
"LAGRANGE, (JOSEPH LOUIS). - THE INTRODUCTION OF THE 'GRAVITATIONAL POTENTIAL' THE PRIZE-WINNING MEMOIR.
Reference : 44971
(1776)
Prix D'Astronomie Physique sur L'èquation séculaire de la Lune.
(Paris, Imprimerie Royale, 1776). 4to. Extracts from ""Mémoires de Mathematique et de Physique, Présentés à l'Academie des Sciences par divers Savans"", Année 1773. Pp. 1-61. A faint dampstain to right margin of the first leaves, otherwise fine and clean.
First printing of this importent memoir as it represents THE EARLIEST INTRODUCTION OF THE IDEA OF THE POTENTIAL, the ""Gravitational Potential"". The potential of a body at any point is the sum of the mass of every element of the body when divided by its distance from the point. Lagrange showed that if the potential of a body at an external point were known, the attraction in any direction could be at once found.""For the prize of 1774, the Academy asked whether it were possible to explain the secular equation of the moon by the attraction of all the celestial bodies, or by the effect of the nonsphericity of the earth and of the moon. Lagrange, who was equal to the scope of the subject, felt very stale and at the end of August 1773 withdrew from the contest. At d’Alembert’s request Condorcet persuaded him to persevere. He was granted an extension and thanked the jury for this favor in February 1774. He took the prize with ""Sur l’équation séculaire de la lune."" (DSB).Parkinson ""Breakthroughs"", 1773 P.
"CLAIRAUT, ALEXIS-CLAUDE. - CORRECTING NEWTON'S INVERSE SQUARE LAW.
Reference : 53475
(1746)
De L'orbite de la Lune dans le Systeme de M. Newton.
(Paris, L'Imprimerie Royale, 1746). 4to. Without wrappers. In ""Histoire de L'Academie Royale des Sciences. Année MDCCXLIII. Avec les Memoires de Mathematiques & de Physique, pour la même Année."" Pp. 17-32 and 3 folded engraved plates.
First printing of this controverial paper. ""In 1743 Clairaut read before the Academy a Paper entitled ""L’orbite de la lune dans le systeme de M. Newton,"" Newton was not fully aware of the movement of the moon’s apogee, and therefore the problem had to be reexamined in greater detail. However, Clairaut - and d’Alembert, and Euler, who were also working on this question - found only half of the observed movement in their calculations. It was then that Clairaut suggested completing Newton’s law of attraction by adding a term inversely proportional to the fourth power of the distance. This correction of the law elicited a spirited reaction from Buffon, who opposed this modification with metaphysical considerations on the simplicity of the laws of nature. Clairaut, more positive and more a pure mathematician, wanted to stick to calculations and observations. The controversy that arose between these two academicians appears in the Mémoires of the Academy for 1745 (published long afterward)."" (DSB).
