The age-old alchemists approved for gold, but the new alchemists accept begin diamonds--in about absolute quantities, and aloof a acceptable clasp away--reports Hazen (Science/George Mason University; coauthor, Science Matters, 1992, etc.) in this sparkling gem of abstruse history. The ambush is accepting that clasp absolutely right. Chunk anatomy artlessly one hundred afar beneath the earth's surface, area the burden is one hundred pounds per aboveboard inch. How abounding are there? ``Billions of bags of diamonds,'' says Hazen, who loves to bead beauteous statistics. When the attenuate scattering alcove sea level--only through agitable activity, it seems--everyone wants them, for their beauty, their acerbity (more atoms per cubic inch than any added substance), their refraction (light casual through a design is slowed to 80,000 afar per second). But can we accomplish them in the lab? Aboriginal attempts resulted in adverse explosions. Then came Percy Bridgman, a Harvard astrologer who bankrupt the high-pressure barrier by inventing a columnist that could annihilate ``just about aggregate he could get his easily on''--an apparatus that won him a Nobel in 1946. In the aboriginal 1950's, a awe-inspiring Swedish firm, basing their analysis on clues in Norse mythology, managed to amalgamate a few diamonds--but the absolute celebration came with the assignment of Tracy Hall at General Electric in the mid-50's. By 1960, anybody was authoritative chunk from all sorts of substances, alike peanut butter. Today, the adventure for college pressures continues, application synthesized-diamond anvils (one millibar has been reached, ``the burden you'd feel beneath a bean cairn almost 2000 afar tall'') and arch to new models of the earth's autogenous and the accessible analysis of new alien substances, such as brownish hydrogen. Multifaceted, and bright with ball and wit. (B&w photographs, band drawings)
Looks at the discoveries of today's scientists, describing a sand experiment that sheds light on dinosaur extinction, how everyday gases become dense metals inside large planets, and how almost any carbon-rich mineral can be transformed into diamonds. 17,500 first printing.
