Disagreements concerning which definition to accept are analogous to disagreement among, for example, physicists concerning the correct theory for unifying

gravitational theory with quantum theory.

In this collaborative program, involving NIST, JPL, the University of Colorado, and the Harvard-Smithsonian Center for Astrophysics, a laser-cooled cesium clock will be put aboard the International Space Station in 2005 to perform certain tests on

gravitational theory and to improve upon the realization of the second.

Assumed to be black, the Egyptians are credited with achievements ranging from "experimental aeronautics" to "a possible understanding of quantum physics and
