Galileo’s Early Life Galileo Galilei was an Italian mathematician‚ astronomer‚ physicist‚ and philosopher. He was born in Pisa‚ Italy on February 15‚ 1564. He was the first of six children of Vincenzo Galilei‚ a famous composer‚ and music theorist‚ Giulia Ammannat. Because of his contributions‚ he has been called "the father of observational astronomy"‚ "the father of modern physics"‚ "the father of science"‚ and "the father of modern science". Early in life he wanted to join the Church Order‚ however

The Tuscan physicist‚ mathematician and philosopher Galileo Galilei constructed one of the earliest telescopes which he pointed towards the heavens. Galileo observed the moons of Jupiter‚ the phases of Venus and the rough features of the moon. This new evidence conflicted with the Ptolemaic

Khadijah Ricks Professor Jim Delise Mosasics II 4/20/2015 Galileo vs. the Moon Truther When Galileo first turned his telescope to the moon‚ he had no idea that he was about to see something that would cast doubt upon centuries-old beliefs. At the time of Galileo‚ science was based upon the teachings of Aristotle. According to Aristotle‚ the Earth was the center of the universe. All heavenly bodies‚ including the moon‚ were perfect spheres that moved around the Earth with circular motions or combinations

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

Humans have always been wildly fascinated about the possibility that extraterrestrial life could‚ does currently‚ or has existed elsewhere in the universe. This is a subject that has been questioned by humankind for at least 2000 years. Lucretius‚ a Roman poet from the first century B.C.‚ had suggested that “just as life originated by spontaneous chemical interactions on Earth‚ ‘we must acknowledge that such combinations of other atoms happen elsewhere in the universe to make worlds such as this

raised in a small farming community in Streator Illinois and later moved to a family farm in Western Kansas. He had his first look through a telescope at age 14 and was hooked. He eventually began making his own telescopes and would go on to build over 30 in his lifetime. (http:starchild.gsfc.nasa.gov‚ Clyde Tombaugh) After building one particular telescope‚ one with a very accurate 9 inch reflector‚ he sent drawings of Jupiter and Mars to astronomers at the Lowell Observatory in Flagstaff Arizona

EXPERIMENT: 1 Object: To find the wavelength of Sodium light by Newton’s ring. Apparatus required: A Plano convex lens of large radius of curvature‚ optical arrangement for Newton’s rings‚ plane glass plate; sodium lamp and traveling microscope. Formula used: The wavelength of light is given by the formula λ =D n2+p –Dn2 / 4pR Where D n+p = diameter of (n+p)th ring Dn = diameter of n th ring‚ P = an integer number‚ R = radius of curvature of the curved face of the Plano- convex lens.
