Since the dawn of time, man has yearned to know the origin of existence, how life was started, and the source of creation. Many scientists, from ancient Greece to modern civilization, began the search for answers by first studying our solar system, mapping the stars, trying to unlock their secrets. These eight scientists paved the way for any basic knowledge of the universe.Born in 270 BC, the Greek astronomer Aristarchus of Samos, was the first scientist known to suggest that the earth revolves around the sun. Little is known of the childhood of Aristarchus, as well as his entire life. His only recorded works come from Archimedes and Plutarch, which discuss his ideas of the movement of all the planets in the solar system. Unfortunately, the lack in technological advances greatly affected his observations, making them inaccurate, especially his geometrical equations. The major contribution Aristarchus is known for is a more precise scale of our solar system. Aristarchus of Samos is honored today with a lunar crater named for him, which is also the brightest point on the moon.Claudius Ptolemaeus, also known as Ptolemy, is considered one of the greatest and most influential astronomers of the ancient world. Almost all of his observations and works were done in Alexandria, Egypt, the home of the largest library and school of the ancient world, which when found, greatly benefited scientists in decoding the ancient astronomers calculations and theories. The life of Ptolomy is vague, as is the reaction to his works at the time. His system of astronomy, which is in his book the Syntaxis, was accepted as correct until the year 1543 AD. In this system, the earth was the center of the universe, and was the axis of a huge rotating sphere, which spun. On the outer edges of the sphere were the stars, and the sun and other heavenly bodies were in between the earth and stars. Ptolomy accounted for the movement of the planets using three mathematical...
