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...
Thirty-five-year-old Eugene Markley Landis, A.B., M.S., M.D., Ph.D., of Philadelphia is the brightest young U. S. doctor who came to the attention of the College of Physicians during the past year. Dr. Landis' specialty is measuring the flow of blood through the capillaries. To do that, he uses glass tubes one five-thousandth of an inch in diameter which he inserts into the tiny bores of capillaries. The manner in which capillary blood rises in those tubes has thrown a considerable light on how heart disease causes dropsy, how kidney diseases develop, how a bruised...
...fairness to that beautiful little island it should be known that the leper settlement occupies only about six or seven square miles on a low lava flow peninsula which projects from the foot of the sheer cliffs, 1,500 to 2,000 ft. high, forming the imposing north coast of the island. The settlement is accessible from the remainder of the island only by a very steep and narrow foot and horse trail, carefully guarded. In fact the settlement is closer, insofar as accessibility is concerned, to Oahu than to the remainder of Molokai...
...Hurja sold his Texas paper, took his wife to a Manhattan apartment on Riverside Drive, settled down with sheets of statistics to chart the flow of gold and oil, their output and their probable consumption...
...sits thumbing the pages and tells the Democratic high command: "We have this State sure-waste no effort on it." "We are certainly going to lose that State-ignore it." "Now here's a doubtful State that may be won or lost!" To Boss Farley who directs the flow of campaign funds, to the President who has a speech to make, a WPA project to announce, such advice is invaluable...
