"Although the Earth and moon orbit around one another, the gravitational effects of the moon on the Earth aren't simple, explained Miller. By following the moon closely, Lick researchers propelled scientific understanding of geologic processes on earth, including continental drift. 'At the time, a lot of people still didn't believe in continental drift,' noted Wampler. The experiment contributed a grand new chapter to a story that goes back thousands of years, noted Wampler. 'The moon has been used for a very long time in cosmology,' he said. 'The Greeks in 300 B.C. knew the distance to the moon with about 5 percent accuracy.' The moon figured prominently in the development of Isaac Newton's theory of gravity, as well as in Einstein's theories about cosmology." [Ref6: Lick Recollections 2009]
