...blood samples. This takes time, and sometimes technicians make mistakes. Now researchers at Manhattan's Sloan-Kettering Institute, working with electronics experts, have found a more foolproof blood-counter: a TV microscope. A small TV camera, mounted on a microscope, scans the blood on a slide. As the beam covers the slide, it counts the patches of light and dark made by the blood cells, and an electronic computer compensates for cells of varying sizes...
...undergo complete ground courses, covering Civil Air regulations, CW code reception, meterology, navigation, airway traffic control, radio, and study of the aircraft that is to be flown (Including fuel, oil, electric, and hydraulic systems, engines, and their overhaul) and a refresher course in instruments. prospective pilots practice orientation and beam bracketing. A pilot starts as third crew member and works his way to captain...
...that use quartz fibers as springs, can weigh only tiny quantities. Scales big enough to handle good-sized samples are not nearly as sensitive. Last week Dr. Alsoph H. Corwin of Johns Hopkins University told about a scale that he has developed which is both strong and sensitive. Its beam teeters on a finely polished knife edge of boron carbide (almost as hard as diamond), resting on the same material. The edge is so sharp that the pressure on its minute bearing surface is 25,000 Ibs. per sq. in. It must be handled with extraordinary care to keep this...
Early in 1903, rolls of completed blueprints were rushed up to Boston. Experts in the College's engineering department conducted laboratory experiments through the Spring, and finally decided a cement beam with twisted steel rods running through it would be stronger and cheaper than either stone, brick, or steel. This reinforced concrete was used throughout the structure...
...have been an 18th century camel. Another girl came as a white rabbit, with neither explanation nor apology. Host Cuevas himself received his guests as a timeless "God of Nature" in cloth of gold, a scarlet cape and a headdress of gilded grapes and ostrich plumes in the full beam of a glaring spotlight. "I can't see you; oh, this light is terrible," he cried to one couple as his own limelight blinded him. "You look completely black to me." The couple whispered an explanation : they were dressed in skintight black. Guest after guest fell into deep curtsies...
