...week, the Harvard Square-Arlington line will be replaced by buses. Traffic in the Square will become a little more congested, and the carbon monoxide fumes a little thicker. But down below, the lights will still cast their eerie shadows, and footsteps will rattle in the sooty vaults to the same regular, timed changor and roar of the subway
...dynamometer: the engine is stripped of its load, ideally tuned and hooked up directly to the instrument. Thus, an advertised 200 h.p. engine may deliver that much on the test stand, but much less in actual torque delivered to the rear wheels of the car. After 3,000 miles, carbon deposits drain off 10 h.p.; a hot summer day robs the engine of another 20 h.p. because hot air decreases fuel mixture efficiency; another 20 h.p. goes to operate the fan belt, water pump, generator, etc.; still another 20 h.p. is lost in bearing, transmission and tire friction. With gadgets...
Modern archeological methods-including electrical soil probes and carbon 14 dating-are stripping bit by bit the ancient mystery from Stonehenge, the great megalithic monument on Britain's Salisbury Plain. Stonehenge's origin had been forgotten even in Roman times. Now the diggers know the age of different parts of it, where the great stones came from, and what sort of people dragged them to Salisbury Plain. At the Bristol meeting of the British Association for the Advancement of Science, Prehistorian R.J.C. Atkinson of the University of Edinburgh told the latest Stonehenge theories...
...Bedouin story smells," huffed a professor of rabbinical literature. Others insisted that the manuscripts were forgeries. One scholar, disputing the manuscripts' antiquity, contemptuously referred to them as a "garbage collection." But the antiquity of the scrolls was soon proved conclusively by paleographical and archaeological evidence and by carbon-14 and other tests...
Developed for the Army Chemical Corps, diffusion board resembles ordinary wood-pulp fiberboard, ⅝ in. thick. Impregnated with special chemicals (the kinds are still classified), it acts much like an ordinary Army gas mask, filters out gases and germ-carrying particles as well as radioactive dust, lets oxygen and carbon dioxide breathe through. Against direct radiation itself, the porous diffusion board gives no protection. Thick lead or concrete shields must be used to keep out death-dealing gamma rays. Moreover, lining the walls of an average home with the board would not eliminate dust, which could sift in over windowsills...
