Tycho And Kepler

The extraordinary, unlikely tale of Tycho Brahe and Johannes Kepler and their enormous contribution to astronomy and understanding of the cosmos is one of the strangest stories in the history of science. Kepler was a poor, devoutly religious teacher with a genius for mathematics. Brahe was an arrogant, extravagant aristocrat who possessed the finest astronomical instruments and observations of the time, before the telescope. Both espoused theories that seem off-the-wall to modern minds, but their fateful meeting in Prague in 1600 was to change the future of science. Set in one of the most turbulent and colourful eras in European history, when medieval was giving way to modern, Tycho and Kepler is a double biography of these two remarkable men.

On his deathbed in 1601, the Danish nobleman and greatest naked-eye astronomer, Tycho Brahe, begged his young colleague, Johannes Kepler, "Let me not seem to have lived in vain." For more than thirty years-- mostly in his native Denmark and then in Prague under the patronage of the Holy Roman Emperor, Rudolph II-- Tycho had meticulously observed the movements of the planets and the positions of the stars. From these observations he developed his Tychonic system of the universe-- a highly original, if incorrect, scheme that attempted to reconcile the ancient belief that the Earth stood still with Nicolaus Copernicus's revolutionary rearrangement of the solar system some fifty years earlier. Tycho knew that Kepler, the brilliant young mathematician he had engaged to interpret his findings, believed in Copernicus's arrangement, in which all the planets circled the Sun; and he was afraid his system-- the product of a lifetime of effort to explain how the universe worked-- would be abandoned. In point of fact, it was. From his study of Tycho's observations came Kepler's stunning three Laws of Planetary Motion-- ever since the cornerstone of cosmology and our understanding of the heavens. Yet, as Kitty Ferguson reveals, neither of these giant figures would have his reputation today without the other. The story of how their lives and talents were fatefully intertwined is one of the more memorable sagas in the long history of science. Set in a singularly turbulent and colorful era in European history, at the turning point when medieval gave way to modern, Tycho & Kepler is both a highly original dual biography and a masterful recreation of how science advances. From Tycho's fabulous Uraniborg Observatory on an island off the Danish coast to the court of the Holy Roman Emperor, Rudolph II; from the religious conflict of the Thirty Years' War that rocked all of Europe to Kepler's extraordinary leaps of understanding, Ferguson recounts a fascinating interplay of science and religion, politics and personality. Her insights recolor the established characters of Tycho and Kepler, and her book opens a rich window onto our place in the universe.

Describes the scientific partnership between sixteenth-century astronomer Tycho Brahe and his colleague and student, mathematician Johannes Kepler, and the influence of Tycho's naked-eye observations of planetary movements on Kepler's Three Laws of Planetary Motion, the cornerstone of cosmology.

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.

When Newton said, I have stood on the shoulders of giants, he was referring, above all, to the astronomers, Johannes Kepler and Tycho Brahe. Kepler was an obsessive, devout teacher, many of whose astronomical theories were quite mad, yet he had an analytical ability second to none. Brahe, by contrast, was an arrogant, cruel, extravagant aristocrat who believed the Sun orbited the Earth, yet he was one of the best observational astronomers of all time. Their serendipitous meeting in Prague in 1600 led to an extraordinary - and uneasy - alliance and resulted in a huge leap forward in the understanding of astronomy. Brahe's observational data and Kepler's genius combined to produce the first three laws of planetary motion. Set in one of the most turbulent and colourful eras in European history, at the turning point where mediaeval gave way to modern, this book tells the story of a major watershed in the history of human thought.

Nicholas Jardine offers here an edition and the first translation into English of Johannes Kepler's A Defence of Tycho against Ursus. He accompanies this with essays on the provenance of the treatise - the circumstances which provoked Kepler to write it, an analysis of its strategy, style and historical sources and of the contents of Ursus' Treatise on Astronomical Hypotheses to which Kepler was replying. Dr Jardine also provides three extended interpretive essays on the intrinsic interest and historical significance of the work.

Johannes Kepler was an obsessive, devout teacher of astronomy, and Tycho Brahe was a cruel, extravagant aristocrat who believed the sun orbited the Earth. Kepler's analytical abilities were said to be second to none, while Brahe was one of the best observational astronomers of all time. Their meeting in Prague in 1600 led to an extraordinary, if uneasy, alliance which eventually resulted in a huge leap forward in the understanding of astronomy. Together they produced the first three laws of planetary motion. This book tells the story of a major watershed in the history of human thought.
