A Daily Telegraph book of the year. This is a landmark in science writing that resurrects from the vaults of neglect the polymath Jerome Cardano, a Milanese of the sixteenth century. Who is he? A gambler & blasphemer, inventor & chancer, plagued by demons & anxieties, astrologer to kings, emperors, & popes, & the unacknowledged discoverer of the mathematical foundations of quantum physics. The Quantum Astrologer`s Handbook, like Jerome, has multiple occupations: it is at once a biography, a history of science, an explanation of quantum theory, & an engrossing story which reads like the best kind of novel. It is a science book like no other about a scientist like no other.
