Presenting motion pictures taken in the NACA's new "superspeed" wind tunnel at Langley Field, Va., where airflow up to 750 m.p.h.* is possible, Dr. Lewis proved that at 575 m.p.h. the smooth flow of air over the wing top suddenly breaks away in a feathery "shock wave" which completely nullifies lifting power. Cause is an area of excessively compressed air, built up by the airfoil's passage. Same phenomenon occurs at the tips of propellers. Only chance for speed greater than 575 m.p.h. is a mechanism for changing wing and propeller shape when the plane reaches...
...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. In the Schrödinger wave mechanics, the little symbol ψ is important. It stands, roughly, for statistical probability. Instead of locating the electron, it locates a region in which the electron probably occurs...
...stage was a potbellied, high-wheeled coach usually pulled by six horses. Inside were seats for nine, but as many as 35 persons were known to ride at a time. At first the driver was the only man in charge. Then, as the wave of highway robbery began, there was an armed guard as well. Both men were generally the highest type of western dare-devil-the driver invariably out to break the speed record; the guard ready to shoot it out with any number...
...first meeting of the Radio Club during the second semester, President MacDonald Nyhen '36 last night demonstrated the operation of the new short wave transmitter which the executive committee has recently constructed...
...side was the label, "Dictatorial Rowers of the President over All Foreign Trade". If another log, called "Export Interests" had not suddenly appeared and bumped the big log away, the little child night have been drowned. As it was the collision of the two caused a foaming wave of Protest, and as his mouth was open in surprise at the suddenness of it all, he swallowed a good part of that wave. It tasted terribly bitter; with it in his stomach he knew that he could swim no further...
