Freeman Dyson, world-renowned astrophysicist, dreams of exploring the heavens and has designed an inexpensive spaceship to take him there. George Dyson, a brilliant dropout, lives in a tree in coastal British Columbia and is designing a giant seagoing canoe. Both men are intensely, passionately dedicated to their visions. Kenneth Brower explores the relationship of this odd father-son duo, whose goals could hardly be more different yet whose approaches are inevitably alike, with insight and sensitivity.
An unusual and often moving double biography...In their individual ways, the Dysons embody the extremes of twentieth-century life -- science and technology, and the revolt against them. -- The New Yorker
