Dava Sobel

By 1514, the reclusive cleric Nicolaus Copernicus had written and hand-copied an initial outline of his heliocentric theory-in which he defied common sense and received wisdom to place the sun, not the earth, at the center of our universe, and set the earth spinning among the other planets. Over the next two decades, Copernicus expanded his theory through hundreds of observations, while compiling in secret a book-length manuscript that tantalized mathematicians and scientists throughout Europe. For fear of ridicule, he refused to publish.

In 1539, a young German mathematician, Georg Joachim Rheticus, drawn by rumors of a revolution to rival the religious upheaval of Martin Luther's Reformation, traveled to Poland to seek out Copernicus. Two years later, the Protestant youth took leave of his aging Catholic mentor and arranged to have Copernicus's manuscript published, in 1543, as De revolutionibus orbium coelestium (On the Revolutions of the Celestial Spheres)-the book that forever changed humankind's place in the universe.

In her elegant, compelling style, Dava Sobel chronicles, as nobody has, the conflicting personalities and extraordinary discoveries that shaped the Copernican Revolution. At the heart of the book is her play And the Sun Stood Still, imagining Rheticus's struggle to convince Copernicus to let his manuscript see the light of day. As she achieved with her bestsellers Longitude and Galileo's Daughter, Sobel expands the bounds of narration, giving us an unforgettable portrait of scientific achievement, and of the ever-present tensions between science and faith.

Inspired by a long fascination with Galileo, and by the remarkable surviving letters of his daughter Maria Celeste, a cloistered nun, Dava Sobel has crafted a biography that dramatically recolors the personality and accomplishments of a mythic figure whose early-seventeenth-century clash with Catholic doctrine continues to define the schism between science and religion-the man Albert Einstein called "the father of modern physics-indeed of modern science altogether." It is also a stunning portrait of Galileo's daughter, a person hitherto lost to history, described by her father as "a woman of exquisite mind, singular goodness, and most tenderly attached to me."

Moving between Galileo's grand public life and Maria Celeste's sequestered world, Sobel illuminates the Florence of the Medicis and the papal court in Rome during the pivotal era when humanity's perception of its place in the cosmos was about to be overturned. During that same time, while the bubonic plague wreaked its terrible devastation and the Thirty Years' War tipped fortunes across Europe, Galileo sought to reconcile the Heaven he revered as a good Catholic with the heavens he revealed through his telescope. Filled with human drama and scientific adventure, Galileo's Daughter is an unforgettable story.

Praise for Galileo's Daughter:

"[Sobel] shows herself a virtuoso at encapsulating the history and the politics of science. Her descriptions of Galileo's ideas…are pithy, vivid, and intelligible."—Wall Street Journal

Anyone alive in the eighteenth century would have known that "the longitude problem" was the thorniest scientific dilemma of the day—and had been for centuries.  Lacking the ability to measure their longitude, sailors throughout the great ages of exploration had been literally lost at sea as soon as they lost sight of land.  Thousands of lives and the increasing fortunes of nations hung on a resolution.  One man, John Harrison, in complete opposition to the scientific community, dared to imagine a mechanical solution--a clock that would keep precise time at sea, something no clock had ever been able to do on land.  Longitude is the dramatic human story of an epic scientific quest and of Harrison's forty-year obsession with building his perfect timekeeper, known today as the chronometer.  Full of heroism and chicanery, it is also a fascinating brief history of astronomy, navigation, and clockmaking, and opens a new window on our world.
