Moon clouds. The illuminated area of the visible sphere (degree of illumination) is given by formula_3, where formula_4 is the elongation (i.e., the angle between Moon, the observer (on Earth) and the Sun). The gravitational attraction that masses have for one another decreases inversely with the square of the distance of those masses from each other. As a result, the slightly greater attraction that the Moon has for the side of Earth closest to the Moon, as compared to the part of the Earth opposite the Moon, results in tidal forces. Tidal forces affect both the Earth's crust and oceans. The
East of the Sun (and West of the Moon) East of the Sun (and West of the Moon) "East of the Sun (and West of the Moon)" is a popular song written by Brooks Bowman, an undergraduate member of Princeton University's Class of 1936, for the 1934 production of the Princeton Triangle Club's production of Stags at Bay. It was published in 1934 and soon became a hallmark of the Princeton Tigertones, one of Princeton University's all-male a cappella groups. The standard is also sung by the Princeton Nassoons, Princeton University's oldest a cappella group. "East of the Sun" was first recorded by Hal Kemp for Brunswick Records on
