...green leaves the chlorophyll is arranged in flat disks like piles of plates. Biologists suspected that this delicate laminated structure had something to do with photosynthesis, but they could not make sense out of it until Bell Telephone Laboratories invented its solar battery, an electronic device made of thin layers of treated silicon. When sunlight hits the battery, it knocks electrons out of one of the silicon layers. Caught by another silicon layer, the electrons turn into a useful electric current. Hearing about this principle, Dr. Calvin and other scientists speculated that the thin layers of chlorophyll might capture light...
...magnetic field and shot extremely high-frequency radio waves through it. When strong light was shone on the chlorophyll, some of the radio energy was absorbed. This proved to Dr. Calvin that chlorophyll exposed to sunlight contains free electrons, and is therefore capturing light energy by the layer-to-layer method. Nature's green plants. Dr. Calvin believes, have turned out to be electronic solar batteries invented millions of years before human scientists ever thought of electronics...
Nevertheless, It Moves ... In Hurst Green, Sussex, England, Policeman Ronald Marshall halted a prewar pickup truck, noted grass growing on one running board, an inch-long piece of metal in one tire, a triple-layer canvas patch on another, was assured by the driver, "I think the guv'nor is going to take it off the road soon...
...designed by nature to plod the surface of the earth and occasionally to flounder in the uppermost layer of its waterways, gets into trouble when he tries to go either up or down. The medical hazards of high-altitude flying have long been studied. Until recently, the corresponding dangers of the deep have been the private preserve of Navy "diving doctors" working with submariners and deep-sea divers. Now, with the craze for skindiving, with Aqua-Lungs, snorkels and similar gadgets sold in the corner store, civilian doctors are daily confronted with unfamiliar problems. In the New England Journal...
...gate receipts over $300,000, plus a 5% bonus if he beats Pro Champ Pancho Gonzales, Rosewall will go on a 13-month tour with Jack Kramer's traveling tennists. But the sad truth is that even with Rosewall gone, Australia has a thick layer of talented young players to throw against a thin line of undertrained and only mildly promising U.S. youngsters...
