Copernicus and Ptolemy Astronomy is one of the oldest sciences. Two of the greatest astronomers of all time are Claudius Ptolemy and Nicolaus Copernicus. These men had very different ideas and theories. Claudius Ptolemy was born around 100 A.D. and died around 165 A.D. He was considered one of the greatest Greek astronomers and geographers of ancient times. Very little is known about him, but he did his observations of astronomy in Alexandria, Egypt. His works are known as Almag

ISAAC NEWTON The world would be very different from how it is now if it weren t for Isaac Newton. His discoveries are the foundation of science as we know it today. Many people consider him to be the father of modern science. Many of his equations and formulas are still used by scientists and mathematicians all over the world. One of the many fields of study Isaac Newton helped to advance was astronomy. Before Newton s time, the movements of the planets were thought to have been contr

Radio astronomy uses radio waves to study regions of space. Radio waves are a form of electromagnetic radiation - like visible light waves only with much longer wavelengths. Visible light waves are oscillating electromagnetic signals with wavelengths of less than one millionth of a metre, whereas radio waves have wavelengths in the range of a few millimetres to several metres. Radio telescopes gather and concentrate the radio waves from an astronomical source. The signal received is then ele

Pythagorean Theorem The Greek philosopher Pythagoras of Samos is responsible of great advances in the study of astronomy, mathematics and the theory of music. A tyrant ruled Samos at the time and Pythagoras fled to southern Italy at about 532 BC. In Croton, Pythagoras founded a religious school that also specialized in philosophy. Pythagoras's school made outstanding advances and contributions to the study of mathematics. His school was very private and secretive which made it hard for re

August Ferdinand Möbius was born on November 17, 1790 in Schulpforta, Germany. (Then called Saxony.) He was the only child of Johann Heinrich Mobius, a dancing teacher. She was related to the famous Martin Luther, the man responsible for writing the document known as the 96 Thesis. Möbius himself was home schooled until he was thirteen. Showing an avid interest in mathematics, he went to college in Schulpforta, Germany in 1803. When Möbius graduated from college in 1809 he became

Edwin Hubble, was an American astronomer who has had an enormous impact on science, often compared to Isaac Newton and Galileo. Hubble has helped change our thoughts and perception of the universe in two important ways. First, Hubble confirmed the existence of other galaxies other than the Milky Way, during a time when many people thought the Milky Way was the entire universe. Secondly, with the help of other astronomers, he confirmed that the universe was expanding at a constant rate by de

Nicolas Copernicus Nicolas Copernicus 1473-1543 Physics February 8, 2000 Nicolas Copernicus Nicolas Copernicus 1473-1543 Copernicus was born in Poland in 1473, he started his education at Cracow University. There he studied mathematics and optics. From here he went to Italy, where he was appointed as a canon in the cathedral of Frauenburg, where he spent a comfortable academic life studding. Copernicus had some small hobbies while at the cathedral, he painted, and frequently

ASTRONOMY A New Black Hole Scientific American September 13, 2000 Evidence that the heavens house a previously unknown type of black hole was reported by scientists yesterday. Data from NASA s Chandra X-Ray Observatory revealed a hole was some 600 light-years from the center of the starburst galaxy M82. The brightness of the x-ray source indicates that this moon-size hole has the mass of at least 500 suns, making it intermediate between stellar black holes and the supermassive black ho

Galileo was an Italian physicist and astronomer who with the German astronomer Johannes kelper initiated the scientific revolution that began the work of Sir Isaac Newton. Galileos main interest was astronomy he used the telescope which he invented using optic lenses to see sunspots on the sun loonier mountains and valleys the four largest satellites of Jupiter and the phases of Venus. He also discovered the laws of falling objects and the motion of moving projectiles. At Padua Galileo inve

Astrology Astrology is the study of how events that happened on earth depending of to the positions and movements of astronomical bodies, including the sun, the moon, planets, and stars. Astrologers (people that study astrology) believe that the position of astronomical bodies at the exact moment of a person’s birth and the following movements of the bodies reflect that person’s character and their destiny. For many years, scientists have rejected the principles of astrology. Sti
