THE HUBBLE SPACE TELESCOPE Telescopes have only been around for about 400 years. Since then‚ they have evolved quickly and helped astronomers make remarkable discoveries. Ground based telescopes were the first‚ but we needed a way to observe the cosmos in the vacuum of space‚ without the light pollution and atmosphere of earth. The Hubble Space Telescope (HST) was the tool that helped propel astronomy to the next level. It has helped us understand the universe in new ways‚ but Hubble

had believed that the universe was static‚ even Albert Einstein himself tried to modify the equations of General Relativity to allow for a static universe. They were all wrong! In 1929 an American astronomer named Edwin Hubble was (1) studying the redshift from other galaxies when he noticed that they were moving away from ours. Alexander Friedmann had earlier solved the equations of General Relativity to show models of the universe where the universe was actually expanding despite Einstein modifying

Chapter One Introduction to Geology "study of the Earth." Geology literally means Physical geology examines the materials and processes of the Earth. Historical geology examines the origin and evolution of our planet through time. • Geology is an evolving science - the theory of plate tectonics was just accepted in the 1960’s. • • . Geology seeks to understand the origin of our planet and our place in the Universe - answers to these questions are also posed outside of the realm

HISTORY OF ASTRONOMY Astronomy is the oldest of the natural sciences‚ dating back to antiquity‚ with its origins in the religious‚ mythological‚ and astrological practices of pre-history: vestiges of these are still found in astrology‚ a discipline long interwoven with public and governmental astronomy‚ and not completely disentangled from it until a few centuries ago in the Western World . In some cultures astronomical data was used for astrological prognostication. Ancient astronomers were able

troChapter 1: Charting the Heavens (Astronomy Today) SUMMARY The universe is the totality of all space‚ time‚ matter‚ and energy. Astronomy is the study of the universe. A widely used unit of distance in astronomy is the light year‚ the distance traveled by a beam of light in one year. Early observers grouped the thousands of stars visible to the naked eye into patterns called constellations. These patterns have no physical significance‚ although they are a very useful means of labeling regions

Applications of Differential Forms Maxwell Faraday and Maxwell Ampere Equations R. M. Kiehn (in preparation - last update 10/31/97) Physics Department‚ University of Houston‚ Houston‚ Texas Abstract: The topological universality of the Maxwell Faraday and Maxwell Ampere equations is an artifact of C2 differential forms on a domain of dimension n * 4. Starting with a 1-form of (electromagnetic) Action‚ the Maxwell Faraday equations become a consequence of the Poincare lemma. Starting from an
