BLACK HOLES A TRAVELER'S GUIDE Clifford Pickover's inventive and entertaining excursion beyond the curves of space and time. I've enjoyed Clifford Pickover's earlier books ...now he has ventured into the exploration of black holes. All would-be tourists are strongly advised to read his traveler's guide. -Arthur C. Clarke. Many books have been written about black holes, but none surpass this one in arousing emotions of awe and wonder towards the mysterious structure of the universe. -Martin Gardner. Bucky Fuller thought big. Arthur C. Clarke thinks big, but Cliff Pickover outdoes them both. -Wired. The book is fun, zany, in-your-face, and refreshingly addictive. -Times Higher Education Supplement.
