Carbon and its compounds are well-known in galactic gas-clouds, and in the atmosphere and core of stars, which burn helium to produce carbon. Carbon is the sixth element in the periodic table, and forms about two-tenths of one percent of Earth's crust. photosynthesizes, or reads F&SF) is constructed mostly of waterlogged carbon, with a little nitrogen, phosphorus and such for leavening. There are over a million known and catalogued compounds of carbon: the study of these compounds, and their profuse and intricate behavior, forms the major field of science known as organic chemistry. Since prehistory, "pure" carbon has been known to humankind in three basic flavors. First, there's smut (lampblack or "amorphous carbon"). Then there's graphite: soft, grayish-black, shiny stuff -- (pencil "lead" and lubricant). And third is that surpassing anomaly, "diamond," which comes in extremely hard translucent crystals. Smut is carbon atoms that are poorly linked. Graphite is carbon atoms neatly linked in flat sheets. Diamond is carbon linked in strong, regular, three-dimensional lattices: tetrahedra, that form ultrasolid little carbon pyramids. Today, however, humanity rejoices in possession of a fourth and historically unprecedented form of carbon. Researchers have created an entire class of these simon-pure carbon molecules, now collectively known as the "fullerenes." They were named in August |
