7-14-95. NYPaper Page Oner: "2 Groups of Physicists Produce Matter That Einstein Postulated." By chilling a cloud of atoms to a temperature barely above absolute zero, scientists at a Colorado laboratory have at last created a bizarre type of matter that had eluded experimenters ever since its potential existence was postulated by Albert Einstein 70 years ago. The creation of this Bose-Einstein condensate -- named for Einstein, and the Indian theorist Satyendra Nath Bose -- was hailed yesterday as the basis of a new field of research expected to explain some fundamental mysteries of atomic physics. A Texas group later produced similar results. The achievement should allow physicists to peer directly into the realm of the ultrasmall. MYS_fit [This was also reported in The Economist of July 1.]
