Kepler and the Universe: How One Man Revolutionized Astronomy
Author: David K. Love
Publisher: Prometheus Books
Pages count: 253
Description: 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.
I have this book in epub format. Do I have to upload it and create a new entry ? Can I use the existing one and how ? I hope a moderator can help me...
OK; I will try (first time !)
