Some scientists matter-of-factly dismiss the problem of creation. Says Harvey Tananbaum, an X-ray astronomer at the Harvard-Smithsonian Astrophysical Laboratory: "That first instant of creation is not relevant as long as we do not have the laws to begin to understand it. It is a question for philosophers and religionists, not for scientists." Adds Geoffrey Burbidge, director of Kitt Peak National Observatory: "Principles and concepts cannot be measured. A question like 'Who imposed the order?' is metaphysical." Still, virtually everyone -both scientists and laymen-is taken by the sheer unthinkable opacity of the creation...
Twenty-six teams of organic chemists have labored to synthesize the molecule since 1962, when an X-ray diffraction by William N. Lipscomb Jr., Lawrence professor of Chemistry, culminated efforts to determine the structure of gibberellin...
...instrument on board the cylindrical observatory is a 1,440-kg (3,200-Ib.) X-ray telescope, which is larger and has higher resolving power than any other ever built. From its perch high above the earth's obscuring blanket of air, it will provide new and sharper images of the myriad and puzzling sources of X rays found across the skies-and new insights into such bizarre phenomena as quasars, pulsars and black holes. As Harvard Astrophysicist Jonathan Grindlay put it: "We are at the dawn of a new era in our understanding of the universe." In honor...
...pcke, 18, was one of West Germany's more promising young boxers. Just last year the sturdily built youth was runner-up in his nation's junior heavyweight competitions. Now KÖpcke's career has been brought to an abrupt halt by an X-ray device known as the CAT scanner...
Reaching out to the edges of the known universe (10 billion light years), the observatory's x-ray telescope will be able to detect and study radiat resources at thousand times faint than those observed previously. Riccardo Giacconi, professor of Astronomy and director of the new satellite (dubbed the "Einstein Observatory"), said last week...
