Hydrology and Hydrography Overview from Science Service
Hydrology studies water and uses the hydrologic cycle. It traces the ocean to atmosphere via evaporation and back to land as precipitation, shaping the charts used to understand water movement and availability. The summary notes the U S context of these ideas.

Silicon in Sand to Power Future Industry and Chemistry
Silicon, the earth’s second most abundant element after oxygen, will shape future industry as a metal and in compounds. Silicone chemistry yields liquids that stay fluid at low temperatures and greases with stable viscosity, plus a rubber and a bouncing putty, while silicon’s electrical uses promise new devices.

Trilobites Dominate Early Life on Earth in 100 Year Scale
On a 100 year scale the trilobites rose as the dominant life form for about eight years, roughly 500 million to 300 million years ago. They formed a separate class within the arthropod phylum alongside insects and persisted long after their peak.
Trilobite Facts and Human Reflections on Extinction
The text notes trilobites ranged from one to four inches on average, with the largest about 18 inches, and over 1,000 species. They dominated ancient seas comprising 60 percent of animal life and preyed on smaller creatures before going extinct. Today humans eat lobster and study fossils, pondering future fates.
Bugs Likely to Cause Record Loss Across U S Farms
The article warns that insects may cause about four billion dollars in US damage in 1950. It lists pests from grasshoppers on the plains to corn borers in the Midwest and boll weevils in the South, detailing control efforts and expected crop losses nationwide.

Water's Supersonic Barrier Studied by Navy Science Lab
Navy researchers at White Oak Maryland study effects of supersonic water entry on torpedoes and naval weapons. A one eighth inch steel sphere entering water at 6870 feet per second creates air and water shock waves with a 2 000 000 g deceleration. High speed photography records scale model tests to ensure weapons are safe and effective.
