A History of Arabic Astronomy: Planetary Theories During the Golden Age of Islam - George Saliba - كتب Google A History of Arabic Astronomy is a comprehensive survey of Arabic planetary theories from the eleventh century to the fifteenth century based on recent manuscript discoveries. George Saliba argues that the medieval period, often called a period of decline in Islamic intellectual history, was scientifically speaking, a very productive period in which astronomical theories of the highest order were produced. Based on the most recent manuscript discoveries, this book broadly surveys developments in Arabic planetary theories from the eleventh century to the fifteenth. Taken together, the primary texts and essays assembled in this book reverse traditional beliefs about the rise and fall of Arabic science, demonstrating how the traditional “age of decline” in Arabic science was indeed a “Golden Age” as far as astronomy was concerned.
Thomas Edison Edison as a boy Thomas Alva Edison (February 11, 1847 – October 18, 1931) was an American inventor and businessman. He developed many devices that greatly influenced life around the world, including the phonograph, the motion picture camera, and a long-lasting, practical electric light bulb. Galileo Galilei Galileo Galilei (Italian pronunciation: [ɡaliˈlɛːo ɡaliˈlɛi]; 15 February 1564 – 8 January 1642), often known mononymously as Galileo, was an Italian physicist, mathematician, engineer, astronomer, and philosopher who played a major role in the scientific revolution during the Renaissance. His achievements include improvements to the telescope and consequent astronomical observations and support for Copernicanism. Galileo has been called the "father of modern observational astronomy", the "father of modern physics", the "father of science", and "the father of modern science". Early life
Michelangelo Michelangelo di Lodovico Buonarroti Simoni (6 March 1475 – 18 February 1564), commonly known as Michelangelo (Italian pronunciation: [mikeˈlandʒelo]), was an Italian sculptor, painter, architect, poet, and engineer of the High Renaissance who exerted an unparalleled influence on the development of Western art. Despite making few forays beyond the arts, his versatility in the disciplines he took up was of such a high order that he is often considered a contender for the title of the archetypal Renaissance man, along with his fellow Italian Leonardo da Vinci. In a demonstration of Michelangelo's unique standing, he was the first Western artist whose biography was published while he was alive. Two biographies were published of him during his lifetime; one of them, by Giorgio Vasari, proposed that he was the pinnacle of all artistic achievement since the beginning of the Renaissance, a viewpoint that continued to have currency in art history for centuries.

Elizabeth Smart kidnapping Elizabeth Smart was abducted from her bedroom in Salt Lake City, Utah on June 5, 2002. She was 14 at the time. She was found alive nine months later on March 12, 2003, in Sandy, Utah, about 18 miles from her home, in the company of Brian David Mitchell and Wanda Ileen Barzee, who were indicted for her kidnapping, but initially ruled unfit to stand trial. Barzee, in 2009, and Mitchell (then 57), in 2010, were eventually convicted. He was held in the Salt Lake County Jail following his sentencing on May 25, 2011. On August 31, he was transferred to federal prison to begin serving a life sentence for his crimes.
Tusi couple An animated model of a Tusi couple. Original description Tusi's diagram of the Tusi couple If two coplanar circles, the diameter of one of which is equal to half the diameter of the other, are taken to be internally tangent at a point, and if a point is taken on the smaller circle—and let it be at the point of tangency—and if the two circles move with simple motions in opposite direction in such a way that the motion of the smaller [circle] is twice that of the larger so the smaller completes two rotations for each rotation of the larger, then that point will be seen to move on the diameter of the larger circle that initially passes through the point of tangency, oscillating between the endpoints. 
Albert Einstein Albert Einstein (/ˈælbərt ˈaɪnʃtaɪn/; German: [ˈalbɐrt ˈaɪnʃtaɪn]; 14 March 1879 – 18 April 1955) was a German-born theoretical physicist. Einstein's work is also known for its influence on the philosophy of science. He developed the general theory of relativity, one of the two pillars of modern physics (alongside quantum mechanics).:274 Einstein is best known in popular culture for his mass–energy equivalence formula E = mc2 (which has been dubbed "the world's most famous equation"). He received the 1921 Nobel Prize in Physics for his "services to theoretical physics", in particular his discovery of the law of the photoelectric effect, a pivotal step in the evolution of quantum theory. Near the beginning of his career, Einstein thought that Newtonian mechanics was no longer enough to reconcile the laws of classical mechanics with the laws of the electromagnetic field. This led to the development of his special theory of relativity. Life
Johannes Kepler Johannes Kepler (German: [ˈkʰɛplɐ]; December 27, 1571 – November 15, 1630) was a German mathematician, astronomer, and astrologer. A key figure in the 17th century scientific revolution, he is best known for his laws of planetary motion, based on his works Astronomia nova, Harmonices Mundi, and Epitome of Copernican Astronomy. These works also provided one of the foundations for Isaac Newton's theory of universal gravitation. During his career, Kepler was a mathematics teacher at a seminary school in Graz, Austria, where he became an associate of Prince Hans Ulrich von Eggenberg. Later he became an assistant to astronomer Tycho Brahe, and eventually the imperial mathematician to Emperor Rudolf II and his two successors Matthias and Ferdinand II.
Raphael Raffaello Sanzio da Urbino (April 6 or March 28, 1483 – April 6, 1520), better known simply as Raphael, was an Italian painter and architect of the High Renaissance. His work is admired for its clarity of form and ease of composition and for its visual achievement of the Neoplatonic ideal of human grandeur. Together with Michelangelo and Leonardo da Vinci, he forms the traditional trinity of great masters of that period. Kidnapping of Jaycee Lee Dugard The kidnapping of Jaycee Lee Dugard occurred on June 10, 1991, in South Lake Tahoe, California. Dugard was 11 years old at the time and was abducted from a street while she was walking from home to a school bus stop. Searches began immediately after the kidnapping, but no reliable leads were generated. She remained missing for more than 18 years.
XORP XORP is an open source Internet Protocol routing software suite originally designed at the International Computer Science Institute in Berkeley, California. The name is derived from eXtensible Open Router Platform. It supports OSPF, BGP, RIP, PIM, IGMP, OLSR. In July 2008, the International Computer Science Institute transferred the XORP technology to a new entity, XORP Inc., a commercial startup founded by the leaders of the opensource project team and backed by Onset Ventures and Highland Capital Partners. In February 2010, XORP Inc. was wound up, a victim of the recession. However the open source project continued, with the servers based at University College London. In March 2011, Ben Greear became the project maintainer and the www.xorp.org server is now hosted by Candela Technologies.
