About the original discovery in 1985 of a third form of solid carbon, named Buckminsterfullerene after the architect who invented geodesic domes. The two scientists who discovered the material glimpsed it for brief seconds only in their lasers but neither they nor other scientists subsequently could make the substance last long enough in the laser to prove their theory. Then in 1990, a couple of physicists with an arc-welder in a bell-jar found they could make as much Buckminsterfullerene as they liked, and industrial applications opened up, with talk of new polymers, molecular ball-bearings, lubricants and super- conductors. Meanwhile, the original discoverers were turning back to the fundamental questions surrounding the discovery, such as how and why does it form; does it exist in space or is it the solution to one of the great mysteries of the universe.
