Harvard still boasts many a faculty giant like the Law School's Roscoe Pound and Felix Frankfurter, Philosopher Alfred North Whitehead, Physicist Percy Williams Bridgman, Astronomer Harlow Shapley, but in time they must yield and withdraw as Economist Frank William Taussig and Shakespearean George Lyman Kittredge did this year (TIME, Feb. 17). To replace them. President Conant admits, will be harder now that the growth of State Universities has pushed Harvard from its "natural pre-eminence," made it uncertain that a promising young scholar will heed the once undeniable "call" from Cambridge...
Others are Irving W. Bailey and Ralph H. Wetmore for one investigation; Kenneth T. Bainbridge, John C. Baker, Henry B. Bigelow, Percy W. Bridgman, Huntington Brown, Frank M. Carpenter, Arthur Casagrande, Phillip C. Rutledge, William B. Castle, Dana B. Durand, John T. Edsall, Louis C. Graton, Ernest B. Dane, Jr., Alden B. Greninger, Richmond L. Hawkins...
...other and their combined weight rested on a postage stamp, the resultant pressure would be some 1,440,000 lb. per sq. in. Such a pressure, Harvard University announced last week, has been produced in its physics laboratories by stocky, soft-spoken Percy Williams Bridgman and maintained for 15 hours on a speck of graphite as big as a pinhead...
That was a special experiment. For routine high-pressure work Dr. Bridgman uses about half the maximum, working up to 720,000 lb. and then down again in one hour. Even that squeeze has not been duplicated elsewhere. In principle the Bridgman pressure apparatus is simple, like Archimedes' theoretical lever with which the old Greek said he could move the world. It is a hydraulic press, in which is utilized the fact that a piston bearing on a small area of a confined liquid delivers its pressure against every other area of equal size in the tank. Thus...
Hitherto Professor Bridgman has had to confine his experiments to a pressure of 12,000 atmospheres. Some tests were made as high as 20,000, but the apparatus was continually breaking. The steel cylinders bulged like lead...
