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.
