    about their work, their goals, or their methods (Hodgkin, 40). Regardless of the motivation for pursuing mathematical astronomy, we see some impressive mathematical books written by Hippocrates, Plato, Eudoxus, Euclid, Archimedes, Apollonius, Hipparchus, Heron and Ptolemy. I will argue that Ptolemy was the most integral part of the history of Greek astronomy. Mathematics and astronomy are very closely related. It is the mathematical procedures which help define time and space. However, Greek culture

    Astronomy in Babylonia was one of the first moments in history which gave evidence to the strong use of mathematical theory, before this it was believed that the earth was surrounded by a great mass on to which the stars were attached. Magic, mysticism and the heavens was a huge influence on astronomy of those times. However, around 400BC mathematics began to play a crucial role in determining lunar and solar theories as well as planetary movement. Epping and Kugler were two scholars who having discovered

    Breakthroughs in Astronomy and Medicine in the 16th and 17th Centuries It was during the 16th and 17th centuries when man's view of the unvierse and himself changed drastically. This came after a millenium of repetition and stagnation in the development of science. People finally began questioning what they were told, and they went out to find proof rather than assuming on the basis of authority and common sense. These advances in astronomy and medicine came about in the same era, and were

    One thing us as humans have never been able to fully understand is astronomy. Always having an unexplained mystery, astronomy also has served as a way to keep time and predict the future. The word “astronomy” is defined as the study of heavenly bodies, meaning anything in the sky such as stars, galaxies, comets, planets, nebulae, and so on. Many people, if not everyone, is amazed by the night sky on a clear, moonless night. Astronomy dates back to ancient times when peoples such as the Babylonians

    On a clear night, only a few hundred stars can be seen without the use of any astronomical instruments. The Milky Way Galaxy consists of at least 200 billion stars. Stars are huge balls of hot gases. The sun is a star, but it is not the largest star; it is only the nearest star. A star has three recognizable stages: its birth; the years in which it exists; and its death. Its formation and its life expectancy have captured the curiosity of astronomers for centuries. Astronomers from the past have

    lived from 1661 to 1696. Here is where he studied physics and astronomy, and created calculus. Newton became interested in mathematics in the autumn of 1663 when he tried to read an astrology book but could not understand it because he had little knowledge of trigonometry and geometry. What got his mind going was when he read that parallelograms upon the same base and between the same parallels are equal. He then returned back to the astronomy book with a greater understanding and interest. In the summer

    THE TELESCOPE Since the beginning of astronomy, astronomers had a unanimous goal: to see farther, better and in greater details. The earliest known telescope was created by Hans Lippershey in 1608. Others have claimed to have made the discovery of telescope but according to documents, he is the earliest who has applied for the patent. The telescope had an convex objective lens and a concave eyepiece. A year later, using such an early refracting telescope, Galileo Galilei, an Italian physicist and

    Greek Geometry Although the original roots of geometry can be traced to the Egyptians, the Greeks built on most Egyptian theories that we use today. Greek astronomy and Greek geometry were both used in order to answer many difficult questions of the time. Without geometry, the study of astronomy would have been almost impossible, and vice versa. Even though many Greek theorems and principles were later built on by geniuses such as Einstein and Lobachevsky, the basis still remains the same. The
