Margaret O. Hyde, author of New Ideas in Science, Atoms Today and Tomorrow and Flight Today and Tomorrow, etc. celebrates the current International Geophysical Year with a book covering up-to-date accounts of Science's findings beneath the sea, into the earth and outward in the path of long range experimental rockets. Her report includes word of water warmed by nature for the city of Roykjavik, Iceland; of five cloud seeding companies which offer rain-making facilities to customers in 18 states; of Bell Telephone Company's $10,000 experimental solar-powered batteries which are operating experimentally in the South; and of Operation Deep Current, science's wary watch on the piles of atomic trash which are deposited in cases on the ocean bottom. Layman-language strengthens the appeal of an intri ally interesting book.
