Kepler and the Universe: How One Man Revolutionized Astronomy by David Love

A contemporary of Galileo and a forerunner of Isaac Newton, Johannes Kepler (1571-1630) was a pioneering German scientist and a pivotal figure in the history of astronomy. This colorful, well-researched biography brings the man and his scientific discoveries to life, showing how his contributions were every bit as important as those of Copernicus, Galileo, and Newton. 

It was Kepler who first advocated the completely new concept of a physical force emanating from the sun that controls the motion of the planets--today we call this gravity and take it for granted. He also established that the orbits of the planets were elliptical in shape and not circular. And his three laws of planetary motion are still used by contemporary astronomers and space scientists.  
The author focuses not just on these and other momentous breakthroughs but also on Keplers arduous life, punctuated by frequent tragedy and hardships. His first wife died young, and eight of the twelve children he fathered succumbed to disease in infancy or childhood. He was frequently caught up in the religious persecutions of the day. His mother narrowly escaped death when she was accused of being a witch.

Intermingling historical and personal details of Keplers life with lucid explanations of his scientific research, this book presents a sympathetic portrait of the man and underscores the critical importance of Keplers discoveries in the history of astronomy.

Johannes Kepler

David Love, Who was Johannes Kepler? The year was Copernicus had been dead for 28 years and his great idea of a heliocentric universe had received virtually no public support. Tycho Brahe was a young man of Galileo and Shakespeare were both 7 years old. And Johannes Kepler was born, on 27 December at 2.

While Copernicus rightly observed that the planets revolve around the Sun, it was Kepler who correctly defined their orbits. At the age of 27, Kepler became the assistant of a wealthy astronomer, Tycho Brahe, who asked him to define the orbit of Mars. Brahe, who had his own Earth-centered model of the Universe, withheld the bulk of his observations from Kepler at least in part because he did not want Kepler to use them to prove Copernican theory correct. Using these observations, Kepler found that the orbits of the planets followed three laws. Eventually, however, Kepler noticed that an imaginary line drawn from a planet to the Sun swept out an equal area of space in equal times, regardless of where the planet was in its orbit.

On this day in B. Kepler is best known for his theories explaining the motion of planets. Kepler was born on December 27, , in Weil der Stadt, Germany. Copernicus believed that the sun, not the earth, was the center of the solar system, a theory that contradicted the prevailing view of the era that the sun revolved around the earth. Over the next decade, Kepler learned about the work of Italian physicist and astronomer Galileo Galilei , who had invented a telescope with which he discovered lunar mountains and craters, the largest four satellites of Jupiter and the phases of Venus, among other things. Kepler corresponded with Galileo and eventually obtained a telescope of his own and improved upon the design.

    Johannes Kepler, German astronomer who discovered three major laws of His discoveries turned Nicolaus Copernicus's Sun-centered system into a dynamic universe, Kepler himself did not call these discoveries “laws,” as would become.
