...mile-long vacuum tube. Before the measurements were complete he died. Grizzled Dr. Francis Gladheim Pease of Mt. Wilson and Fred Pearson, longtime Michelson assistant, carried on. Two years ago they announced that their measurements were showing systematic variations, an astounding situation which raised the question of whether light speed was a constant after all (TIME...
Last week final results were published in the Year Book of the Carnegie Institution. Average velocity, in four series of measurements over periods of two to five months, was 186,270.75 mi. per sec. Best modern figure for light's speed, this is almost 14 mi. per sec. slower than the results of ten years ago. Inconstancies between individual measurements were ascribed to experimental error or "disturbing influences of unknown origin." But no doubt was expressed that the true velocity of light is indeed a constant constant...
...facts and stirring them around until a connecting theory emerges does not work. Speculation and intuition are supremely necessary. What sets Dr. Einstein apart is the quality of his intuition. There have been abler mathematicians than he. But from a very few observations-the constancy of light's speed in space and the equivalence of gravitational mass and inertia-he divined how the cosmos was made. He did not, like Newton, invent mathematics to describe it but borrowed the mathematics of Riemann, Fitzgerald, Lorentz and Minkowski...
...present man's closest penetration to the heart of reality is not single but double. Relativity deals with time, space, gravity, the finite speed of light; quantum mechanics with particles, electricity, the action of light. The two are not only separate but in some cases conflict. Relativity dispenses with the idea of absolute time; quantum mechanics retains it. Although it is a tremendously powerful approach to atomic behavior, quantum mechanics is shot through with uncertainty. It has given birth to the Uncertainty Principle of Heisenberg, which states that the position and velocity of an electron cannot be simultaneously ascertained...
...media have featured this important work, and Mr. Goodwin of the Massachusetts Registry of Motor Vehicles has volunteered to provide space for Dr. de Silva's apparatus. Persons who have been deprived of their operator's licenses and others interested are to be tested on machines which register the speed of their reactions, their excitability, power to steer a straight course, and various other attributes necessary to expert driving...
