The importance of mathematics to nature has been a topic of debate within the Western scientific tradition. From ancient times through the middle ages, an outbreak of mathematical creativeness was often followed by centuries of inactivity. As we all know, mathematics has always been the vital importance in astronomy, and many ancient astronomers were also mathematicians. This means that the growth of mathematics was applied and motivated by astronomical calculations. Though, not everyone studying ancient astronomy was capable to use applications of mathematics. The first developments of mathematical astronomy came during the Mesopotamian and Babylonian eras, when the techniques were developed to predict eclipses and positioning of the celestial …show more content…

Among the techniques developed and improved by them included geometry of triangulation and three dimensional applications. Greek astronomy took a crucial turn in the 4th c. with Plato (427-348) and his newer contemporary Eudoxus of Cnidus (390 – 337 B.C.). The famous Greek philosopher, Plato, was one of the most important figures of Greek mathematics who helped revolutionize geometry. His representations of various three-dimensional shapes represented a hypothetical model where the entire universe was connected through constellations and stars. He played a significant role in encouraging and inspiring Greek intellectuals to study mathematics as well as philosophy. As he was known for having math ideas that were influenced by Pythagoras and Egyptians algebraic arithmetic, he argued that the four elements (earth, water, air and fire) can be reduced to regular geometrical solids, which are reducible in turn to triangles. Therefore, for him, the fundamental building blocks of the world were geometrical. He was certain that geometry was the key to unlock the secrets of the universe (Lindberg …show more content…

The two-sphere model is a geocentric model which divides the cosmos into two regions: a spherical Earth, central and motionless (the sublunary sphere) and a spherical heavenly realm centered on the Earth, which may contain multiple rotating spheres made of aether. In one of his books, Plato described the two-sphere model and said there were eight circles or spheres carrying the seven planets and the fixed stars. He put the celestial objects in an order: Moon, Sun, Venus, Mercury, Mars, Jupiter, Saturn and Fixed stars, and proposed a question for the Greek mathematicians of his day: “By the assumption of what uniform and orderly motions can be apparent motions of the planets be accounted for?” (Lloyd 1970, p84). Eudoxus took Plato’s challenge and assigning each planet a concentric sphere. He tilted the axes of the spheres and by assigning each a different period of revolution, he was able to approximate the celestial “appearances”. Therefore, he was the first to attempt a mathematical description of the motions of the planets (Heliocentrism
