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.

Favorite watch / solar
Color: Green/Green
I'm partial... I have bought Timex my intire life, they no doubt make the best watches... They take a licking, but keep on ticking is there old commercials.. True.. Great quality, keeps going after many year's... I never bought a solar watch from them prior I have to mention... It should hold up I'm thinking like their battery watches, I hope so. My favorite watch, I own a handful. Watch looks better in person... Downfall, they are trying a new band out of recycled plastic, I don't like it as much as the older bands it's soft, but feels a little strange...

Solar powered
Color: Green/Green
Great watch for us older folks. The hands are large enough to see easily and the fact it is solar powered means batteries do not have to be replaced every year or two.

Nice watch
Color: Green/Green
Very happy with my purchase, rated the purchase with 4 stars due to the band being very stiff, holds doesn't line up to fit wrist properly, don't recommend for seniors to purchase, very difficult to put on.
