... Pierr Simone Laplas.) For his bright intellect and an outstanding achievements in several sciences (astronomy, physics, mathematics) Laplas was called "a French Newton". He became a consistent follower of Newton and rut a task before himself of explaining the planets motion, the movement of their satellites, the ocean rising tides in the Earth and a complicated motion of the Moon. Laplas showed that the planets inequalities should be periodical (based on Newton's gravitation principal). ...

Before you continue reading, you should know that this was not always the case, i.e. the Moon once was rotating with respect to the Earth, so that on every night a terrestrial observer (if there was one, because this was long, long before mankind appeared on our planet, and even before any major animals had appeared) saw another face of the Moon. ... Figure 1 (not to scale) shows how we can imagine the system Earth-Moon...
