The Motion Paradox: The 2,500-Year-Old Puzzle Behind All the Mysteries of Time and Space

The Greek philosopher Zeno sought to reveal that motion and speed were logical impossibilities; one of his famous four paradoxes argued that a moving object can never reach its destination, because it must first travel half the distance, then half the remaining distance, and so on. In this entertaining, informative diversion, Mazur (Euclid in the Rainforest ) spins out the discoveries of the mathematicians and scientists who have grappled with the riddles of time and space over the last two millennia, from Aristotle up to Heisenberg and contemporary string theorists. Yet for all their answers, the fundamental premise that motion is an illusion created by consciousness still remains. Many elements of the story, such as the astronomical breakthroughs of Galileo and Tycho, or the simultaneous development of calculus by Leibniz and Newton, have been discussed in greater detail in other recent books. But Mazur spins a good yarn, and his conversational tone holds readers' attention even as the mathematical formulae pile up in later chapters. (Apr.)
