...last the chemists isolated a small drop (20 mg.) of colorless, oily stuff, odorless to humans but with an enormous attraction for male gypsy moths. It could be diluted almost endlessly. Less than one ten-thousandth of a billionth of a gram (10 -7 microgram) of it was enough to bring eager males fluttering out of the woods. When the potent oil was analyzed, it proved to be a surprisingly simple chemical (10-acetoxy-1-hydroxy-cis-7-hexadecene) that can be synthesized for $5 per Ib. Dr. Jacobson has about 1 Ib. on hand. If it were diluted...
...Mile Beam. The light comes in short bursts a few millionths of a second apart, and they make a flash that lasts less than a thousandth of a second. But the light is incredibly bright and concentrated. When Bell scientists set up the maser at Holmdel, N.J. and pointed its beam to hit the Murray Hill laboratory 25 miles away, the red flashes could be clearly seen with the naked eye, and they registered strongly on photomultiplier tubes. Bell Labs, whose primary interest is in communication, looks forward to perfecting long-reaching maser beams that could carry everything from telephone...
Snakes & Fish. Savely pointed out that nature is full of marvelously sensitive instruments. Rattlesnakes, for instance, find warm prey at night by means of heat-detecting organs that respond to a temperature change of one-thousandth of a degree. No man-made heat seeker can do anything like it. Neither can man-made gadgets approach the electronic virtuosity of those tropical fish that send out pulsed currents of electricity, presumably to keep them in touch with things around them. The system they use is not well understood, but it is known that one kind of fish can detect a current...
...pushed their particles to scheduled speed but delivered only a comparative few. The Soviet 10-Bev accelerator at Dubna is apparently plagued with this trouble. U.S. physicists, who would be quick to praise their Russian colleagues if praise were due, estimate that its pulses contain 10 million protons, one-thousandth of the number in a fat Brookhaven pulse...
...tiny nose-cone test model. When an electric spark explodes the oxygen-hydrogen, it bursts through the diaphragm and into the vacuum. Ahead of it rushes a hot shock wave that hits the test model at actual re-entry speed and temperature. The flow lasts no more than one-thousandth of a second, but it is enough to yield volumes of scientific information. After only six months of work with this violent instrument. Kantrowitz was able to send the Air Force the first firm data about heat and air conditions around a nose cone at its moment of crisis...
