An astronomer charts the story of our quest to measure the distance to a star in this "delightful history of a crucial advance in knowledge" ( Booklist). Since the ancient Greeks, great scientific minds have attempted to determine the distance of stars using the principle of parallax: the apparent shift in an object's position when viewed from different vantage points. Not until the nineteenth century would three astronomers, armed with the best telescopes of the age, race to conquer this astronomical Everest-their contest ending in a virtual dead heat.

An astronomer charts the story of our quest to measure the distance to a star in this "delightful history of a crucial advance in knowledge" ( Booklist). Since the ancient Greeks, great scientific minds have attempted to determine the distance of stars using the principle of parallax: the apparent shift in an object's position when viewed from different vantage points. Not until the nineteenth century would three astronomers, armed with the best telescopes of the age, race to conquer this astronomical Everest-their contest ending in a virtual dead heat. Against a sweeping backdrop filled with kidnappings, dramatic rescue, swordplay, madness, and bitter rivalry, Alan Hirshfeld brings to life the heroes of this remarkable story. Meet the destitute boy plucked from a collapsed building who becomes the greatest telescope maker the world has ever seen; the hot-tempered Dane whose nose is lopped off in a duel over mathematics; the merchant's apprentice forced to choose between the lure of money and his passion for astronomy; and the musician who astounds the world by discovering a new planet from his own backyard. Generously illustrated with diagrams, period engravings, and paintings, Parallax is an unforgettable tale that illuminates the distinctly human side of science.
