41. The equation has played an important role in the history of both physics and mathematics, particularly classical celestial mechanics . 42. The approach modeled phenomena as a physical system observed with error ( e . g ., celestial mechanics ). 43. In 1846, he predicted the existence and position of the planet Neptune by applying the mathematics of celestial mechanics . 44. A notable feature of " Damocles " is its inclusion of relatively detailed celestial mechanics into the game physics. 45. Moser returned briefly to Goettingen to work as Siegel's assistant, writing a book on celestial mechanics with his mentor. 46. Until the rise of space travel in the twentieth century, there was little distinction between orbital and celestial mechanics . 47. In 1989 he obtained his doctoral degree at the University of Heidelberg in Germany with a thesis in celestial mechanics . 48. The classic problem of celestial mechanics is to compute the orbit of a moon, given a known distribution of mass. 49. Another important conserved quantity, discovered in studies of the celestial mechanics of astronomical bodies, is the Laplace Runge Lenz vector. 50. Still Cauchy refused to take any oaths; however, he did feel loyal enough to direct his research to celestial mechanics .
