Golden Tube. The target of the chromatographic detective work performed by the bomb sniffer is the vapor from a chemical called ethylene glycol dinitrate (EGDN), one of the principal components of emissions given off by dynamite. With the aid of a small internal fan, the detector samples air in the vicinity of a suspect object and passes the vapors over a modern equivalent of Tsvett's limestone-a rough gold-plated copper surface that has a special affinity for EGDN. As the molecules adhere to it, their concentration increases. The special surface is then heated...
Spider's Warning. In the future, Blair, together with his Swedish and Russian counterparts, hopes to develop a global warning system to detect pollution. Before their plan is presented at the U.N. World Conference on Environment in 1972, Blair plans to test a prototype station. The system's scope will appear only as a vast number of small details are analyzed. The ability of a spider to spin a web, for example, can be affected by air pollution; mosses, which accumulate lead from the environment, are a good measure of lead pollution. In effect, the system will...
Throughout the conversation, I seemed to detect beneath a superficial cynicism a nostalgia for the past. Jona than Kramer sounded very much like Dickens' Father Time, or like the aged child-cynic, a bitter girl in late adolescence, wishing desperately she could recapture virgin innocence...
Fortunately, the general is enacted by George C. Scott, who can sense a character in a gross script the way a sculptor can detect a man in a block of marble. Beneath the pompous strutting, Scott understands, was a shrewd playwright who devised and played a public character for his troops. The trouble was that after Patton persuaded his audience, he took in himself; the author and his persona became inseparable. Scott shows that strange, mad process and demonstrates how courage could become, in time, suicidal. General Patton is too complex a period piece to be seen by the film...
...past heroin ("horse") was an overwhelming favorite for stimulating horses to run faster, but heroin had unfortunate side effects and some horses became uncontrollably wild. Today's stimulants are much more sophisticated and harder to detect in the post- race spit and urinalysis, but the penalty for use of stimulants- being barred from racing forever- is so severe that the unscrupulous use other methods to help their horse across the wire first...
