...sided mirror. Velocity measurements completed by his successors after Michelson's death yielded an average figure of 186,270.75 miles per second. But in individual runs there were unexplained, periodic variations up to twelve miles a second. At first this caused excitement over possibility that the speed of light might not be constant (TIME, Dec. 25, 1933). The clamor was quieted by attributing the variations to "experimental error." So the velocity of light was re-established as a constant in good standing...
Last week Harvard University announced development of a new apparatus for refining measurements of light's speed still further. It is compact enough to be housed in a small laboratory room and hallway, it eliminates friction as a source of error, and the measurement is automatic-that is, the human eye is not a factor (the Michelson crew aimed their beams by eye) and the clocking is done, in effect, by a photoelectric cell...
...sections per second, then measuring the length of one section. This is like clocking a freight train when you know the length of the cars. If the cars are 30 feet long and you see that two of them pass a given point every second, you know the speed is 60 feet per second...
...technique was worked out by Texas-born, 30-year-old Physicist Wilmer C. Anderson who, on the basis of his experiments so far, believes he has reduced the margin of error in measuring light's enormous speed to two and one-half miles per second. When his program of measurements is completed, he expects to have the most accurate figure ever obtained for the velocity of the universe's fastest thing...
...wife, who is a doctor of medicine and has done valuable research on metabolism. Born to a brewer in Denmark's Jutland 65 years ago, August Krogh (pronounced Krug) was fascinated by beetle larvae at the age of four. At the University of Copenhagen he ripped with great speed and facility through courses in physics, chemistry and biology, specialized in zoology, studied the respiration of marine animals on a Greenland expedition, learned to like seal meat ("sweet, different, not fishy...
