An article discussing current research in the determination of the gravitational constant. Discuss how the Newtonian gravitation constant (G) is known with relatively poor accuracy (only about 0.1%). Moreover, some recent measurements have disagreed more than their respective error limits would permit. Discuss how a new determination uses some very ingenious technology (Science, 282:2230, 1998). The article should be written at a level understandable to the nonspecialist. Include figures and tables as necessary. Include 3-4 bibliographical references, a reading list, 4-6 key words, and 2-3 URL's.
