The Times (London) 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 ofthe planets and the posi- tions ofthe stars. From these observations—he devel- oped his Tychonic system ofthe universe a highly original, if incorrect, scheme that attempted to rec- oncile the ancient belief that the Earth stood still with Nicolaus Copernicus's revolutionary rearrange- ment of the solar system some fifty years earlier. Tycho knew that Kepler, the brilliant young mathe- matician he had engaged to interpret his findings, believed in Copernicus's arrangement, in which all the planets circled the Sun; and hewas afraid his sys- — tem the product of a lifetime of effort to explain — how the universe worked would be abandoned. In pointoffact, itwas. Fromhis studyofTycho's observations came Kepler's stunning three Laws of — PlanetaryMotion eversince the cornerstoneofcos- mologyandour understandingoftheheavens. Yet, as Kitty Ferguson reveals, neither ofthese giant figures would have his reputation today without the other. The story ofhow their lives and talents were fateful- ly intertwined is one ofthe most memorable sagas in the long history ofscience.
