Since antiquity, opposed concepts such as the One and the Many, the Finite and the Infinite, and the Absolute and the Relative, have been a driving force in philosophical, scientific, and mathematical thought. Yet they have also given rise to perplexing problems and conceptual paradoxes which continue to haunt scientists and philosophers. In Oppositions and Paradoxes, John L. Bell explains and investigates the paradoxes and puzzles that arise out of conceptual oppositions in physics and mathematics. In the process, Bell not only motivates abstract conceptual thinking about the paradoxes at issue, but he also offers a compelling introduction to central ideas in such otherwise-difficult topics as non-Euclidean geometry, relativity, and quantum physics. These paradoxes are often as fun as they are flabbergasting. Consider, for example, the famous Tristram Shandy paradox: an immortal man composing an autobiography so slowly as to require a year of writing to describe each day of his life — he would, if he had infinite time, presumably never complete the work, although no individual part of it would remain unwritten. Or think of an office mailbox labelled “mail for those with no mailbox”—if this is a person’s mailbox, how can they possibly have “no mailbox”? These and many other paradoxes straddle the boundary between physics and metaphysics, and demonstrate the hidden difficulty in many of our most basic concepts.

When recent divorcee Meg Altman and her ten-year-old daughter, Sarah, move to New York City to start afresh, they buy the former upper West Side home of an eccentric millionaire. Most bizarre among the brownstone's features is a vault-like steel-encased room with a phone line, emergency supplies, and a wall of closed-circuit TVs monitoring the townhouse. It's called the Panic Room, and it's meant to provide a sense of security. Instead, it just makes Meg nervous. When three burglars break in, Meg and Sarah are forced to seek refuge in the high-tech bunker. They've barely breathed a sigh of relief before they realize the intruders are after something located inside the Panic Room - and they're not leaving until they get it. Terrified and trapped, mother and daughter must use every last resource to fight for their homes...and their lives.
