...battery's strength (one millionth of a watt) is hardly one fly-power, and ninety-nine percent of the energy from the Strontium 90 is still wasted. But the battery is strong enough to work a transistor. RCA believes that its strength can be increased enough to make the battery useful. The Strontium 90 is durable; it loses only half of its power in 20 years...
...describing the virus of poliomyelitis, they had never seen the critter. Now, two teams of investigators working independently have isolated the virus, looked at it long and hard under the electron microscope, photographed it and measured it. It turns out to be a spherical particle almost exactly a millionth of an inch in diameter. Magnified tens of thousands of times against a plastic screen, the virus particles look like tennis balls on an asphalt court...
...California, Drs. Howard L. Bachrach and Carleton E. Schwerdt, did it the hard way.'They grew polio virus of the Type II or Lansing strain in the nerve tissues of rats, and got the concentration up to about 10%. This preparation contained particles of two sizes, some a millionth of an inch in diameter, the others less than half as big. The researchers separated the two kinds in an ultracentrifuge. then they injected the materials into different groups of rats. Only the animals that received the millionth-of-an-inch particles caught polio. That, and similar tests, clinched...
...field in the glass which rotates the light waves so that they pass through both of the polarizing sheets and reach the film of the camera. The light can pass only while the current is flowing, so a very short pulse opens the shutter for as little as one millionth of a second. Some such speed was necessary to picture the doomed tower when it was only half-vaporized by the hungry fireball...
...sacred relics are the standard "meter bars" of platinum-iridium that lie in an underground shrine at Sèvres, near Paris. Replacing a babel of medieval units, they originated in the spurt of innovation that followed the French Revolution. The newfangled meter was intended to be one ten-millionth of the distance between the earth's equator and the North Pole, but difficulties of measurement made the exact length hard to determine. So the meter that was finally accepted (39.37 in. in length) was almost as arbitrary a unit as the ells, feet, rods and pieds...
