The lunar theory (3 risultati)

(London, Richard Taylor, 1834) 4to. No wrappers as extracted from "Philosophical Transactions" 1834 - Part I. Pp. 123-126 a. pp. 127-141. First appearance of Lubbock's "Lunar-Theory"John Lubbock (1803-65), was an astronomer and mathematician. He made a special study of tides and of the lunar theory and developed a method for calculating the orbits of comets and planets. In mathematics he applied the theory of probability to life insurance problems.".…

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 .".…

First printing of these 4 fundamental papers on the perturbations of the moon, as Euler was the first to use of the Calculus on the motion of the moon in relation to the attractive powers of the Moon, the Earth and the Sun. 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.…
