...will determine Nessie's size, her speed of travel, and whether she is, as various eyewitnesses and scientists have declared: 1) an elephant seal which swam in from the North Sea via the Caledonian Canal; 2) a hippopotamus; 3) a 50-ft. prehistoric reptile with a whiskery pinhead and eight scaly humps; 4) a giant squid; 5) "an abomination with a three-arched neck"; 6) a cold-blooded crocodile; 7) a cool fabrication...
Electrons make impressions on photographic emulsions just as light particles do. Using a magnification factor of 20,400, the Siemens & Halske scientists obtained pictures of the pus germ, Staphylococcus aureus, as big as pennies. In photographs with ordinary high-power microscopes, such germs show up pinhead-size...
Explosives. Extremely dangerous are the dynamite-caps or detonators used for blasting in mines. Last year a Baltimore woman, opening the door of a furnace, was struck in the breast by a copper pellet no bigger than a pinhead, which killed her. Investigation showed that the pellet had come from a detonator, no doubt left in the coal by a miner; that such detonators not only hurl a pellet at 6,000 ft. per sec. (three times the speed of a rifle bullet) but throw hundreds of minute shreds of copper, each able to penetrate nearly a millimetre of brass...
...resultant pressure would be some 1,440,000 lb. per sq. in. Such a pressure, Harvard University announced last week, has been produced in its physics laboratories by stocky, soft-spoken Percy Williams Bridgman and maintained for 15 hours on a speck of graphite as big as a pinhead...
TIME'S comparison (Oct. 21, p. 56) of a ripe human ovum with a pinhead gives an inadequate concept of the true size of this interesting cell. Actually its diameter is but 1/200 in. This is about the size of the smallest grain of sand that could be seen with the unaided eye. Stated differently, a sphere having the diameter of a common pinhead (1/12 in.) possesses nearly 4,000 times the volume of a human egg. One can compute further that all the eggs needed to replace the present population of the world could be held...
