...palette knife. What is intended as subtle Human Comedy becomes broadly laughable, as when Jesus and his disciples run through the woods in chromo-colored sequences, or when Mary miraculously appears after a hunter has shot a rosary from a tree branch, or when an unintentionally effeminate devil (Pierre Clementi) pops up in the back of a wrecked automobile...
...Cross Section. Clementi and other IBM scientists stuffed the memory of an advanced computer with equations that described a number of different atoms. Having set up what, in effect, was an electronic chemistry lab, Clementi ordered the computer to produce the mathematical specifications for one molecule of ammonia and one of hydrochloric acid. The obedient computer was then told to move the two molecules together gradually until they combined to form ammonium chloride (commonly called sal ammoniac), a chemical found in such varied products as cough medicines and battery electrolytes...
...interact, the computer sketched them in bright, sharp lines on a television screen. For the first time, scientists were able to examine a cross-section view of the orbits of electrons during a chemical reaction. By ordering the computer to slice through the ammonium chloride molecule at different angles, Clementi developed other cross sections; he was also able to determine exactly how the atoms in the molecule were joined...
Inaccessible Reactions. While it was providing visual information, the computer was also spewing out torrents of printed data describing the energy that binds together a molecule of sal ammoniac. It also spelled out the temperatures and pressures at which the chemical can exist. To Clementi's surprise, the computer revealed that at a temperature around 1300°F-and at high pressure -sal ammoniac, which was previously believed to exist only as a solid, could also be a gas. Two University of Brussels chemists have since produced sal-ammoniac gas in their laboratory, using the computer data for guidance...
...Chemist Clementi firmly believes that test-tube computers will bring new precision to chemistry. They will also enable scientists for the first time to study otherwise inaccessible chemical reactions that occur in the extreme temperatures of rocket engines, for example, or under the stupendous pressures at the center of the earth. "In safety and at their leisure," says Clementi, "they will be able to produce these reactions in a computer that will not melt in the heat or collapse from the pressure...
