One of these was a small telescope that was essential to improve the process of measuring angles, through which it was possible to establish that the period of the solar year lasted 365 days and about 6 hours. 2.1 Pre-Copernican Astronomy Classical astronomy followed principles established by Aristotle. Claudius Ptolemy (about 85-165 CE) lived in Alexandria, Egypt, a city established by Alexander the Great some 400 years before Ptolemy's birth. Under its Greek rulers, Alexandria cultivated a famous library that attracted many scholars from Greece, and its school for astronomers received generous patronage. Sometimes he expanded on the earlier astronomers work. Lived c. 190 BC - c. 120 BC. Under this assumption all celestial bodies describe perfectly circular orbits. Claudius Ptolemy was born in Egypt around AD 85 and died in Alexandria in about AD 165 (the date is not precisely known).

Regardless of the motivation for pursuing mathematical astronomy, we see . Wikipedia the Free Encyclopedia. His ideas about how the universe worked were a mixture of the philosophies of the day, and the results of his own experiments and observations. Ptolemy made his most original contribution by presenting details for the motions of each of the planets. He had inclination toward arts as well as music and poetry composition. Hipparchus of Nicea was a geographer, mathematician, and astronomer who lived between 190 and 120 BC.

It is also known that Ptolemy did not only dedicate himself to systematizing and compiling, work that was already of great importance, but he also made relevant contributions in the field of astronomy, specifically regarding the movement of the planets. It compiles different systems of projection and collection of coordinates of the main places of the world of which it was known"(Garcia, 2003). The exposition of the"Ptolemaic"system meant for him, his most important theory. The greatest contribution of Ptolemy was not the maps themselves but the concepts behind the maps. This is an instrument used to measure the height of the sun through a wooden quadrant and a gnomon, which produces a shadow when the sun illuminates provides a direct measure of the height of the sun. This must be Ptolemy's greatest achievement in terms of an original contribution, . Ptolemy claims that the planets coexist in circular orbits,"epicycles", which prowl central points and, in turn, remain eccentric around the Earth. On which of these assumptions do Ptolemy and Copernicus agree? He also wrote books on optical phenomena and music. Your email address will not be published.

Ptolemy was also characterized by being an outstanding geographer. Required fields are marked *. Another major contribution of Ptolemy to geography was that he instructed on the method of devising maps on both micro and macro scale. In fact, there is information that indicates that Christopher Columbus, the Spanish conqueror, used one of Ptolemys maps on his travels, and that for this reason he considered it possible to reach India by following the west direction.

We are indebted to Aristotle contribution to atomic theory, Aristotle distinguished himself as a student at Plato's Academy in Athens during his youth. When we translate his formulas to sines and cosines, we get the following identities. He argued that mathematics influenced both musical systems and celestial bodies (Wikepedia, 2017). He designed various maps in which he pointed out the most important points, identifying specific coordinates with longitudes and latitudes. Actors are software components that execute concurrently and communicate through messages sent via interconnected ports.

By being able to build on the geocentric model, even if it was an ideal already invented, was a start to being a revolutionary astronomer, so by creating these circular motion measurements called epicycles, Ptolemy was able to continue on to create the Ptolemaic Model, one of his greater contributions. Speaking of his most notable contributions in this field, it can be said that he served as a perfector of the methods of map projection and the presentation - for the first time - of the terms"parallel"and"meridian"to draw the imaginary lines of length And latitude.
