Ancient civilizations generated many innovations that are difficult to explain, such as the remarkable mathematical accuracy of the pyramids of Giza, the man-made fertile soil of the Amazon known as terra preta, and massive stone monuments too heavy to move in Peru and Lebanon, among other places.

Geodesy has undergone technological and theoretical changes of immense proportions since the launching of Sputnik. The accuracy of current satellite geodetic data has approached the centimeter level and will improve by one or two orders of magnitude over the next decade. This bodes well for the application of geodetic data to the solution of problems in solid earth, oceanic and atmospheric sciences. The report Geodesy in the Year 2000 addresses many areas of investigation that will benefit from this improvement in accuracy.
Sally Ride made history as the first American woman in space. A member of the first astronaut class to include women, she broke through a quarter-century of white male fighter jocks when NASA chose her for the seventh shuttle mission, cracking the celestial ceiling and inspiring several generations of women.After a second flight, Ride served on the panels investigating the Challenger explosion and the Columbia disintegration that killed all aboard. In both instances she faulted NASA's rush to meet mission deadlines and its organizational failures. She cofounded a company promoting science and education for children, especially girls.
