After the Vietnam War, Nixon visited China to develop relations with the People's Republic of China. This was one of the first tranquil interactions between Americans and communists. This meeting raised the Soviet Union's interest in detente or peace. Right after visiting China, Nixon visited Moscow where he and Brezhnev agreed on the Strategic Arms Limitation Talks (SALT), limiting the possibility of nuclear war. Nixon used his diplomatic negotiations in China to lead to detente with the Soviet Union.
Copernican heliocentrism is the name given to the astronomical model developed by Nicolaus Copernicus and published in 1543. This model positioned the Sun at the center of the Universe, motionless, with Earth and the other planets orbiting around it in circular paths, modified by epicycles, and at uniform speeds.
The major features of Copernican theory are: Heavenly motions are uniform, eternal, and circular or compounded of several circles (epicycles). The center of the universe is near the Sun. Around the Sun, in order, are Mercury, Venus, the Earth and Moon, Mars, Jupiter, Saturn, and the fixed stars.
Allows calculation of planetary orbital periods around Sun. Allows geometric calculations of planetary distances from Sun. These show nice regularity: more distant planets have longer periods, move slower. Easier to calculate planetary positions than with Ptolemaic model.
