Tom Swift And His Repelatron Skyway

A raging forest fire and daring sky-rescue are only the prologue to young Tom Swift's newest fantastic exploit! From the very moment Tom agrees to help the government of Ngombia unify the new African nation by constructing a transport system to link its two provinces -- separated by thick jungle and an eerie, seething swamp -- he is beset by mysterious adversaries who will not allow Swift Enterprises to succeed where others have failed. Tom comes up with an amazing scientific solution to the problem, an aerial highway suspended over the jungle at treetop height, floating on invisible repelatron beams. But Ngombia holds hidden threats. Weird, gigantic creatures stalk the rain forest, somehow linked to a long-missing scientist and his remarkable discoveries. Magic, menace, and the hatred of one tribe for another complicate the skyway project and threaten to spread to the United States, while the young inventor and his friend Bud face down the fierce challenges of a primeval African land -- haunted by the past. By the author of the YOUNG & SMART series.

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.

Tom constructs a large, heavy brass-bound oak chest to hold his blueprints, formulae, and models until an underground vault can be built. But Tom is attacked and his possessions—including the chest—are suddenly missing, along with hie friend Koku. Tom must discover who stole his Chest of Secrets and save Koku from the villains...if he can!
