Placid Space. The best way to think of space as a navigable medium is to imagine the frictionless surface of a calm, glassy pond. Small objects drift across it easily, propelled by feeble forces. Scattered at wide intervals over the mirror surfaces are deep, sucking whirlpools. If a floating leaf drifts close to one of them, it plunges down to the bottom. A self-powered object, say a water insect, that gets sucked into a whirlpool has a terrible time battling back to the surface...
...watching their bird with Doppler (speed-measuring) radios, saw it pass the critical speed, they knew it would never return to earth. A lesser speed than escape velocity sets a satellite revolving around the earth just free of the atmosphere. A satellite can be compared to a chip or leaf circling around the sides of a whirlpool without escaping from it or immediately being swallowed...
...such as willing"). But for all its words, what the weighty issue added up to was a catalogue of who is solvent-and who is sharp enough to look solvent-in the world of entertainment. It was something for everyone, from Hollywood producers to hall-room has-beens, to leaf through during their idle hours until the next anniversary issue rolls off the presses...
...Cancer Research, the investigators describe ingenious mechanical smokers in which they burned pound after pound of pipe, cigar and cigarette tobacco. To make sure that cigarette paper is not a major factor, they had "all-tobacco" cigarettes specially made-wrapped in ordinary cigarette-tobacco leaf. Then they painted the collected tars on the shaved backs of mice, and counted the resulting cancers. While a mouse's back is admittedly not the same as the inside of a man's lung, histologists (tissue specialists) say that it is of essentially the same structure and shows similar reactions...
Cigar and pipe smokers get less lung cancer than heavy cigarette smokers, but more cancer of the mouth. The researchers got at least as many cancers on mice with cigar and pipe tar as with tar from cigarettes (whether paper-or leaf-wrapped). So, they conclude, if smoking is to be eliminated as a cause of cancer, the dangerous substances must be eliminated from all forms of tobacco...
