The reasons, originally, have been utilitarian rather than scientific; as the apparent motion of the Moon was so intimately connected with the calendar and time keeping for agricultural and cultic purposes. Until the advent of modern astronomy in relatively recent times, the ob

Andreas Strippel motion of the Moon in space, and even more that about its center of gravity, are largely controlled by the Earth — with distant, but powerful, cooperation of the Sun. The aim of the present section will, however, be to focus specific attention on certain dynamical aspects of the Earth-Moon symbiosi
