Beginning with the Chaldaean and Greek theories that Kepler would overturn, this brief biography follows his hard early life, his uneasy partnership with Tycho Brahe in Prague, and the long struggle with Mars that produced his three laws. Bryant, an astronomer at Greenwich, also covers Kepler’s work on optics and refraction and his troubled closing years.
