Download or read book Great Astronomers Nicolaus Copernicus written by Robert Ball and published by CreateSpace. This book was released on 2015-04-30 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: Copernicus, the astronomer, whose discoveries make him the great predecessor of Kepler and Newton, did not come from a noble family, as certain other early astronomers have done, for his father was a tradesman. Chroniclers are, however, careful to tell us that one of his uncles was a bishop. We are not acquainted with any of those details of his childhood or youth which are often of such interest in other cases where men have risen to exalted fame. It would appear that the young Nicolaus, for such was his Christian name, received his education at home until such time as he was deemed sufficiently advanced to be sent to the University at Cracow. The education that he there obtained must have been in those days of a very primitive description, but Copernicus seems to have availed himself of it to the utmost. He devoted himself more particularly to the study of medicine, with the view of adopting its practice as the profession of his life. The tendencies of the future astronomer were, however, revealed in the fact that he worked hard at mathematics, and, like one of his illustrious successors, Galileo, the practice of the art of painting had for him a very great interest, and in it he obtained some measure of success. By the time he was twenty-seven years old, it would seem that Copernicus had given up the notion of becoming a medical practitioner, and had resolved to devote himself to science. He was engaged in teaching mathematics, and appears to have acquired some reputation. His growing fame attracted the notice of his uncle the bishop, at whose suggestion Copernicus took holy orders, and he was presently appointed to a canonry in the cathedral of Frauenhurg, near the mouth of the Vistula. To Frauenburg, accordingly, this man of varied gifts retired. Possessing somewhat of the ascetic spirit, he resolved to devote his life to work of the most serious description. He eschewed all ordinary society, restricting his intimacies to very grave and learned companions, and refusing to engage in conversation of any useless kind. It would seem as if his gifts for painting were condemned as frivolous; at all events, we do not learn that he continued to practise them. In addition to the discharge of his theological duties, his life was occupied partly in ministering medically to the wants of the poor, and partly with his researches in astronomy and mathematics. His equipment in the matter of instruments for the study of the heavens seems to have been of a very meagre description. He arranged apertures in the walls of his house at Allenstein, so that he could observe in some fashion the passage of the stars across the meridian. That he possessed some talent for practical mechanics is proved by his construction of a contrivance for raising water from a stream, for the use of the inhabitants of Frauenburg. Relics of this machine are still to be Been. The intellectual slumber of the Middle Ages was destined to be awakened by the revolutionary doctrines of Copernicus. It may be noted, as an interesting circumstance, that the time at which he discovered the scheme of the solar system has coincided with a remarkable epoch in the world's history. The great astronomer had just reached manhood at the time when Columbus discovered the new world. Before the publication of the researches of Copernicus, the orthodox scientific creed averred that the earth was stationary, and that the apparent movements of the heavenly bodies were indeed real movements. Ptolemy had laid down this doctrine 1,400 years before. In his theory this huge error was associated with so much important truth, and the whole presented such a coherent scheme for the explanation of the heavenly movements, that the Ptolemaic theory was not seriously questioned until the great work of Copernicus appeared. No doubt others, before Copernicus, had from time to time in some vague fashion surmised, with more or less plausibility, that the sun..

Book excerpt: Tycho Brahe was an eccentric Danish astronomer in the 1500s. Growing up in the wealthy home of his uncle, he was provided with the freedom to pursue his ambitions in life. While attending college, Tycho viewed a solar eclipse, which scholars had predicted would happen. He was fascinated that science could predict such phenomenal events, and he devoted much of his time to studying the heavens. Using modern instruments and techniques to measure the positions of the stars and the movements of the planets, Brahe revolutionized the way astronomers viewed the night sky.

Book excerpt: First published in the year 1895, this book is a compandium of informative yet short biographies of some of the greatest astronomers of the world born by that point of time. There are many types of astronomers-from the stargazer who merely watches the heavens, to the abstract mathematician who merely works at his desk; it has, consequently, been necessary in the case of some lives to adopt a very different treatment from that which seemed suitable for others. While the work was in progress, some of the sketches appeared in "Good Words." The chapter on Brinkley has been chiefly derived from an article on the "History of Dunsink Observatory," which was published on the occasion of the tercentenary celebration of the University of Dublin in 1892, and the life of Sir William Rowan Hamilton is taken, with a few alterations and omissions, from an article contributed to the "Quarterly Review" on Graves' life of the great mathematician.

Available in PDF, EPUB and Kindle. Book excerpt: A biography of the brother and sister who helped found modern astronomy Discoverers of the Universe tells the gripping story of William Herschel, the brilliant, fiercely ambitious, emotionally complex musician and composer who became court astronomer to Britain's King George III, and of William's sister, Caroline, who assisted him in his observations of the night sky and became an accomplished astronomer in her own right. Together, they transformed our view of the universe from the unchanging, mechanical creation of Newton's clockmaker god to the ever-evolving, incredibly dynamic cosmos that it truly is. William was in his forties when his amateur observations using a homemade telescope led to his discovery of Uranus, and an invitation to King George's court. He coined the term "asteroid," discovered infrared radiation, was the first to realize that our solar system is moving through space, discovered 2,500 nebulae that form the basis of the catalog astronomers use today, and was unrivalled as a telescope builder. Caroline shared William's passion for astronomy, recording his observations during night watches and organizing his papers for publication. She was the first salaried woman astronomer in history, a pioneer who herself discovered nine comets and became a role model for women in the sciences. Written by the world's premier expert on the Herschels, Discoverers of the Universe traces William and Caroline's many extraordinary contributions to astronomy, shedding new light on their productive but complicated relationship, and setting their scientific achievements in the context of their personal struggles, larger-than-life ambitions, bitter disappointments, and astonishing triumphs.

Download or read book Great Astronomers Nicolaus Copernicus Annotated written by Robert Stawell Ball and published by Independently Published. This book was released on 2019-02-13 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nicolaus Copernicus (1473-1543) was a mathematician and astronomer who formulated a comprehensive heliocentric model which placed the Sun, rather than the Earth, at the center of the universe, contrary to the prevailing thought at his time which placed the Earth at the center.The publication of Copernicus' book, De revolutionibus orbium coelestium (On the Revolutions of the Celestial Spheres), just before his death in 1543, is considered a major event in the history of science.This eBook briefly tells the life of Copernicus and explains his key theories: that the rotation of the Earth causes the apparent daily motion of the objects in the sky, not that the universe rotates around the Earth; that the motion of the planets is better explained with the Sun at the center and the Earth and planets rotating around the sun, rather than the Sun, planets, and stars rotating around the earth; that the sometimes-retrograde motion of Mars is an illusion due to the Earth rotating around the Sun faster than Mars does, not that Mars actually reverses its travel.Although Copernicus correctly deduced that the planets rotate around the Sun, he retained the idea that the orbits were circles. This concept was later overturned by Kepler, who computed that the orbits were elliptical based on accurate measurements of the planets' positions in the sky that were made by Tycho Brahe. (See the volumes about Kepler and Brahe in this eBook series on Great Astronomers.)This is one chapter from Great Astronomers by Sir Richard S. Ball (2nd edition, 1907).

Download or read book Earthshaker written by John Benjamin and published by WestBow Press. This book was released on 2012-10 with total page 304 pages. Available in PDF, EPUB and Kindle. Book excerpt: What in the world is going on? Almost overnight our modern world has entered into a period of great change, very suddenly and unexpectedly, with the largest and most violent storms, earthquakes, solar flares, flooding, droughts, severe weather anomalies, and earth changes than the greater majority of us have ever experienced in our lifetimes. The largest drought ever recorded in America's history struck so quickly in 2012 that it was called a "flash drought," encompassing over half of the entire nation. The full extent of the damage that this has caused through crop loss has yet to be realized on the world's markets, but there will most certainly be food shortages soon, and prices are already beginning to skyrocket worldwide! Water shortages and actual "water wars" are also beginning to occur. The rest of the entire world is also experiencing these same disastrous events. Gigantic earthquakes are happening worldwide causing untold destruction! So many people have lost their lives or have been displaced by these unexpected tragedies that there is simply no way to account for them all. India had a power outage so great that seven hundred million people were without electricity for weeks, and people worldwide fear that something of this same magnitude may also strike their area in the very near future. What in the world is going on here? This book provides the answer to this question and gives sound advice on what you can do to prepare yourself as well as your family and friends to survive the even more severe "earth events" that may be set to occur shortly in our modern, rapidly changing world. It is my earnest hope that this book will be a great help and source of strength for you in the uncertain times that lie directly ahead. John Benjamin

Available in PDF, EPUB and Kindle. Book excerpt: In the mid-1990s, astronomers made history when they began to find planets orbiting stars in the Milky Way. More than eight hundred planets have been found since then, yet none of them is anything like Earth and none could support life. Now, armed with more powerful technology, planet hunters are racing to find a true twin of Earth. Science writer Michael Lemonick has unique access to these exoplaneteers, as they call themselves, and Mirror Earth unveils their passionate quest. Unlike competitors in other races, Geoff Marcy, Bill Borucki, David Charbonneau, Sara Seager, and others actually consult and cooperate with one another. But only one will be the first to find Earth's twin. Mirror Earth tells the story of their competition.

Download or read book Heavenly Intrigue written by Joshua Gilder and published by Anchor. This book was released on 2005-06-14 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heavenly Intrigue is the fascinating, true account of the seventeenth-century collaboration between Johannes Kepler and Tycho Brahe that revolutionized our understanding of the universe–and ended in murder.One of history’s greatest geniuses, Kepler laid the foundations of modern physics with his revolutionary laws of planetary motion. But his beautiful mind was beset by demons. Born into poverty and abuse, half-blinded by smallpox, he festered with rage, resentment, and a longing for worldly fame. Brahe, his mentor, was a flamboyant aristocrat who had spent forty years mapping the heavens with unprecedented accuracy–but he refused to share his data with Kepler. With Brahe’s untimely death in Prague in 1601, rumors flew across Europe that he had been murdered. But it took twentieth-century forensics to uncover the poison in his remains, and the detective work of Joshua and Anne-Lee Gilder to identify the prime suspect–the ambitious, envy-ridden Kepler himself. A fast-paced, true-life account that reads like a thriller, Heavenly Intrigue is a remarkable feat of historical re-creation.

Available in PDF, EPUB and Kindle. Book excerpt: These 100 amazing stars shine a light on astronomy’s greatest hits and their enduring impact on our culture. With roughly 100 billion stars in the Milky Way alone, the cosmos is simply too vast for an unabridged tell-all. But here’s the next best thing: 100 stars—bright and faint, near and far, famous and obscure, long dead and as-yet unborn, red, yellow, blue, and white (but, as you’ll learn, never green)—handpicked by astronomer Florian Freistetter because they have the very best stories to tell: GRB 080319B, the farthest we’ve seen into space with the naked eye Gamma Draconis, the star that proved Earth rotates on its axis V1364 CYGNI, pivotal in the discovery of dark matter 72 Tauri, definitive evidence for Einstein’s theory of relativity V1, which revealed horizons beyond the Milky Way Algol, called the Demon Star for its mysterious blinking—and many more! Freistetter’s short, easy-to-read profiles not only invite you to gaze into the past and future of the universe, they introduce a stellar cast of scientists who came before: from Annie Jump Cannon, who revolutionized how we classify the stars, to Dorrit Hoffleit, who first counted them.
