Conventional scientific wisdom on superconductivity is said to apply only so far as it relates to metallic, low-temperature conductors. The new high-temperature superconductors--the ceramics--have raised fresh questions and de-mand different approaches. How this is being done and its impact in the coming decades is explained by Langone in a reasonably nontechnical fashion, similar to Jonathan Mayo's Superconductivity and Robert Hazen's The Breakthrough (both in LJ 9/1/88). This book explores all the fascinating possibilities about superconductivity. A final, thoughtful chapter entitled ``Japan vs. America'' has policy implications.
