Johannes Kepler: Life and Letters was written as a biography of Johannes Kepler using his own letters. The letters extend over a period of time from 1596 to 1631 bringing to the reader Keplers' personality rather than his scientific achievements. The book represents his youth and years of apprenticeship, marriage and First scholarly achievements, the imperial mathematics at the Court in Prague, the Difficult Years in Linz and the Oddessy of the last four years incompassing 1948 to 1951.

This giant of astronomy considered his studies to be a way of looking into God's creation.

Johannes Kepler is a fascinating man who would revolutionize humanity's conception of the cosmos and its place within them. 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.

Johannes Kepler (1571-1630) is remembered, along with Copernicus and Galileo, as one of the greatest Renaissance astronomers. A gifted analytical thinker, he made major contributions to physics, astronomy, and mathematics. Kepler was trained as a theologian, yet did not hesitate to challenge church doctrine and prevailing scientific beliefs by supporting the theory of a Sun-centered solar system. As Imperial Mathematician to the Holy Roman Emperor, he analyzed the precise observations of the heavens that his predecessor, the great astronomer Tycho Brahe, had recorded. The book follows the ingenious scientist along the difficult pathway from raw data to his monumental discovery--the three Laws of Planetary Motion. Kepler also made fundamental contributions to optical theory, including a correct description of the function of the eye and a new and improved telescope design. His unique Rudolfine Tables, universal calculations of planetary motion, were unprecedented in their accuracy. James Voelkel vividly describes these scientific achievements, providing enough background in astronomy and geometry so even beginners can follow Kepler's thinking and enjoy this book. Equally captivating is his account of Kepler's tumultuous life, plagued by misery, disease, war, and fervent religious persecution. Oxford Portraits in Science is an ongoing series of scientific biographies for young adults. Written by top scholars and writers, each biography examines the personality of its subject as well as the thought process leading to his or her discoveries. These illustrated biographies combine accessible technical information with compelling personal stories to portray the scientists whose work has shaped our understanding of the natural world.

This translation of Johannes Kepler's "New Astronomy", written in 1609, sweeps aside the deductive geometrical approach to astronomy used since ancient times; rejects the uniform circular motions previously used; and attempts to use accurate observations and physical theory.

This translation of Johannes Kepler's "New Astronomy", written in 1609, sweeps aside the deductive geometrical approach to astronomy used since ancient times; rejects the uniform circular motions previously used; and attempts to use accurate observations and physical theory.

Johannes Kepler is remembered today chiefly for the 3 laws of planetary motion known after him. Rejecting the view of those who regarded astronomical hypotheses as mathematical fictions, Kepler sought to derive the true motions of the planets from physical causes. Yet he combined his search for physical causes with a vision of the world as a manifestation of divine harmony. This led him to consider the formal causes or archetypes underlying the world's construction. Kepler's favorite astronomical work, Harmony of the World (Harmonice mundi), was planned in 1599 as a sequel to the Mysterium cosmographicum, although it was not completed & published until 1619. In this vol., the translators have put the Harmony of the World into the kind of clear but earnest language which they suppose Kepler would have used if he had been writing today. Illus.

Arthur Kooestler was a true 20th century man. At various periods in his life he was a refugee, communist, Zionist and democratic-socialist. He was a true cosmopolitan, in the positive sense, and also a student of the history of science. The Watershed is a hymn to a forgotten hero of science - the astronomer J. Kepler who lived in the latter part of the 16th and early part of the 17th centuries. Koestler projects him as a true genius, the father of modern cosmology, who laid the foundation for modern astronomy and who paved the way for Newtonian physics but never realized the importance of his three laws. Kepler was caught between two worlds: the medieval theological world based on Aristotelian physics and modern science based on observation and calculation. If you like he was caught between his heart and his mind. This is readily seen in his works which range from the mystic to the scientific. Keplers three laws were: 1.the planets do not orbit in circles but in ellipses. 2.the speed of the planets vary during their orbit. 3.there is an exact correlation between a planets' period of revolution around the sun and it's distance from the sun: the squares of the periods of revolution of any two planets are as the cubes of their mean distance from the sun. In fact, Kepler had discovered gravity but didn't realize it. This great mind couln't make the the final jump into modernity. This book is a really fine portrayal of Kepler as a great thinker, a man of his times and as Everyman with the same personal problems we all experience. I strongly reccomend this forgotten work to anybody interested in the history of science.

Johannes Kepler contributed importantly to every field he addressed. He changed the face of astronomy by abandoning principles that had been in place for two millennia, made important discoveries in optics and mathematics, and was an uncommonly good philosopher. Generally, however, Kepler's philosophical ideas have been dismissed as irrelevant and even detrimental to his legacy of scientific accomplishment. Here, Rhonda Martens offers the first extended study of Kepler's philosophical views and shows how those views helped him construct and justify the new astronomy. Martens notes that since Kepler became a Copernican before any empirical evidence supported Copernicus over the entrenched Ptolemaic system, his initial reasons for preferring Copernicanism were not telescope observations but rather methodological and metaphysical commitments. Further, she shows that Kepler's metaphysics supported the strikingly modern view of astronomical method that led him to discover the three laws of planetary motion and to wed physics and astronomy--a key development in the scientific revolution. By tracing the evolution of Kepler's thought in his astronomical, metaphysical, and epistemological works, Martens explores the complex interplay between changes in his philosophical views and the status of his astronomical discoveries. She shows how Kepler's philosophy paved the way for the discovery of elliptical orbits and provided a defense of physical astronomy's methodological soundness. In doing so, Martens demonstrates how an empirical discipline was inspired and profoundly shaped by philosophical assumptions.

A towering figure in intellectual history and one of the fathers of modern astronomy, the great mathematician Johannes Kepler (1571–1630) is best known for his discovery of the three laws of planetary motion, which paved the way for a dynamic explanation of the heavenly phenomena. At a time when the Ptolemaic view still prevailed in official circles, Kepler undertook to prove the truth of the Copernican world view and through exceptional perseverance and force of intellect achieved that goal. His epochal intellectual feats are completely and thoroughly described in this splendid work, considered the definitive biography of Kepler. Drawing on a wealth of primary sources, the author presents a fascinating and erudite picture of Kepler's scientific accomplishments, his public life (work with Tycho Brahe, the Danish astronomer; mathematical appointments at Graz, Prague, and Linz; pioneering work with calculus and optics, and more) and his personal life: childhood and youth, financial situation, his mother's trial as a witch, his own lifelong fear of religious persecution, his difficulties in choosing one of eleven possible young women as his second wife, and more, through his last years in Ulm and death in Regensburg.Until his death in 1956, Professor Max Caspar was the world's foremost Kepler scholar. He had spent over two-thirds of his life assembling, cataloging, describing, analyzing, and editing Kepler's works. To this biography he brought tremendous learning and passionate enthusiasm for his subject, creating an unsurpassed resource on the life and work of one of history's greatest scientific minds. Originally published in German and superbly translated into English by C. Doris Hellman, Kepler will fascinate scholars and general readers alike.

The fascinating story of a problem that perplexed mathematicians for nearly 400 years In 1611, Johannes Kepler proposed that the best way to pack spheres as densely as possible was to pile them up in the same way that grocers stack oranges or tomatoes. This proposition, known as Kepler's Conjecture, seemed obvious to everyone except mathematicians, who seldom take anyone's word for anything. In the tradition of Fermat's Enigma, George Szpiro shows how the problem engaged and stymied many men of genius over the centuries--Sir Walter Raleigh, astronomer Tycho Brahe, Sir Isaac Newton, mathematicians C. F. Gauss and David Hilbert, and R. Buckminster Fuller, to name a few--until Thomas Hales of the University of Michigan submitted what seems to be a definitive proof in 1998. George G. Szpiro (Jerusalem, Israel) is a mathematician turned journalist. He is currently the Israel correspondent for the Swiss daily Neue Zurcher Zeitung.

Using previously unstudied sources, this interdisciplinary study considers theology and the beginnings of modern science at the University of Tübingen in the time of Johannes Kepler (1571-1630). The author casts light upon the origins of modern scientific method by examining the relationship between theology, astronomy and dialectics at the university in the work of Kepler’s teachers. Studies of Kepler generally treat him as a precursor of the modern scientist; the influences upon him are identified as Platonist or Pythagorean and his theological interests have often been ignored, or considered as a mystical aberration, unworthy of in-depth treatment. There has been no serious attempt to place Kepler’s work in the wider tradition of mainstream 16th-century thought. This study portrays and analyses the influences and ideas which permeated the life of the university in Tübingen in the second half of the 16th century and places them in relationship to the theology of Martin Luther and Philip Melanchthon. It pays particular attention to the use of theological concepts, astronomical observations, logical demonstrations and the categories of physics, and to the interplay between them.

The work of Johannes Kepler (1571-1630), regarded by many as the founder of modern astronomy, is also historically important to the philosophy and methodology of science as a whole. While most studies of Kepler have concentrated on his astronomical work, particularly his laws describing the revolutions of the planets, the. V. Field focuses on one of Kepler's major preoccupations, his search for the geometrical plan according to which God created teh universe. She demonstrates how Kepler's cosmological theories, which embrace music and astrology as well as astronomy, relate to his other work. Drawing on the whole body of Kepler's writings, Field traces the impact of Plato, Euclid, and Proclus on his thinking, as well as the influence of his contemporaries Galileo and Robert Fludd. Kepler has suffered from a dual image as both hero of science and eccentric mystagogue. Field's sound scholarship provides a more complete picture of the man and his work that will be of value to historians of science, mathematics, philosophy, and the late Renaissance.
