    Diamonds Through the Decades: A Review of South African Production
    by Mike G.C. Wilson The discovery of diamonds in South Africa in 1867 set off a mining boom that continues today. Although the nation no longer dominates world production, as it did from 1870 to 1930, it remains a significant source of high-quality, high-value stones. Offshore mining holds even more promise for the future.

    Focus in School Science: An International Comparison
    by Pamela Jakwerth, Len Bianchi, Curtis C. McKnight, and William H. Schmidt U.S. students lag behind many of their international counterparts in science and math achievement. A comparative study of student performance, curricula, textbooks, and teaching practices in some 50 countries suggests that a lack of focus may be a big part of the problem for science in U.S. schools.

    New Harmony: The Great Scientific Experiment
    by Donald C. Haney and David L. Rice A 19th-century utopian community on the Indiana frontier attracted some of the leading scientists of the time, including geologists William Maclure and David Dale Owen. The town would become a center for the young science and a base for many of the nation's first state and federally sponsored geologic surveys.
