SUPERCONDUCTIVITY
From Discovery to Breakthrough
By Charlene W. Billings
Age Range: 9 - 18
Once over lightly: the frantic race to discover materials that exhibit superconductivity at higher and higher temperatures; today's attempt to make practical superconducting machines and circuits. Slightly marred by minor but irritating typos and arithmetic mistakes, and by jumping from topic to topic with little explication, but useful nonetheless. Many attractive, informative photos; index.
