A Theorem On Planetary Motion Or Sunshine And Shadow

Reprint of the original, first published in 1881.

Thousands of years ago, people looked at the sky in wonder, fascinated by the motions of a few wandering stars. Nobody understood where these wandering objects--now named Mercury, Venus, Mars, Jupiter, and Saturn--came from, why they moved, or what drove their motions through the sky. Today, people know these objects are planets, but the quest to reach this understanding took thousands of years, and the consequences were profound. Famous scientists Johannes Kepler, Edmund Halley, Isaac Newton, and others discovered the laws of gravity and planetary motion, using these laws to explain the workings of the solar system. Their findings allowed the human race to find its way from planet to planet with unmanned probes and eventually allowed people to reach the moon. In "Planetary Motion," learn how scientists have found new planets outside the solar system, and continue their search for planets like Earth.

Johannes Kepler is a fascinating man who would revolutionize humanity's conception of the cosmos and their place within it. He would replace the Ptolemaic system with his three laws that described the orbital motion of the planets around the Sun. This scientist's work continues to inform and facilitate modern advances in technology, astronomy, and astrophysics. In addition to being an enthralling life and times account of a great thinker, this biography also supports Common Core standards for the reading of biographies, historical and scientific accounts, the analyzing of the relationship between primary and secondary sources, and citing evidence to support that analysis.

Abstract:

The text and a sound recording of one of Feynman's lectures, is accompanied by a discussion of the lecture and a brief remembrance of the influential physicist.

Due to his theory of 'immaterialism' and Schopenhauer's regard of him as the 'father of idealism', George Berkeley (1685-1753) is one of the most important thinkers of the Early Modern period. The Bloomsbury Companion to Berkeley is a comprehensive one volume reference guide to his life, thought and work. In twenty six original essays, a team of leading international scholars of Modern Philosophy cover all of Berkeley's writings including unpublished manuscripts and correspondence, thus providing readers with a complete and accessible source of information to the entire corpus of Berkeley's writings. The book includes extended essays on key themes in Berkeley's thought as well as sections covering Berkeley's life and times, and also his intellectual influence and legacy.

A primer for researchers and graduate students; introduces and applies chaos techniques to specific astrophysical systems.
