A More Perfect Heaven: How Copernicus Revolutionized the Cosmos

Dava Sobel. Walker, $24 (288p) ISBN 978-0-8027-1793-1

Sobel, author of the bestselling Longitude and Galileo's Daughter, brings something different to the bulging Copernicus canon. She wants to know why Nicolaus Copernicus (1473%E2%80%931543) waited till shortly before his death to publish the universe-expanding ideas that he had previously only quietly circulated among other scientists. Her conclusion: in the midst of Martin Luther's challenge to the Catholic Church, Copernicus, himself a Church canon, feared the Church's response to his radical notion that Earth revolved around the Sun. His thesis, of course, altered nothing less than the our view of our place in the cosmos. Daringly, Sobel embeds within a factual narrative a two-act play in which she imagines the relationship between the aging Copernicus and a young mathematician (and Lutheran) named Georg Joachim Rheticus, who Sobel says "convinced%E2%80%9D the great astronomer "to publish his crazy idea.%E2%80%9D Delivered with her usual stylistic grace (and here, a touch of astrological whimsy), Sobel's gamble largely succeeds in bringing Copernicus and his intellectually and religiously tumultuous time alive.
