...logical, though not chronological, account of physics, beginning with the kinetic theory of gases and ending with spectroscopy and a discussion of the periodic table of the elements. Three weeks are spent in introducing the basic idea of the quantum theory, as it is evidenced in the photo-electric effect and the spectrum of hydrogen. Each experiment is described and demonstrated prior to the discussion of the theory which explains it. Agreement between theoretical and experimental results is carefully tabulated throughout. The mathematics is limited to algebra; integral signs are banned in order that the nonmathematical student may feel...
...lingering in the park when most of the Press photographers had started ahead to the Roosevelt special train, 27-year-old Sammy Schulman, for 14 years an International News Photo cameraman, was rewarded with a startling action picture of Mayor Cermak a few seconds after he had been wounded. His picture of the bleeding Mayor (see cut) was also distributed through Acme because Acme carried the photograph in its plane to Manhattan. The picture approaches in sensational spontaneity the picture that alert William Warneke made for the oldtime Evening World of New York's Mayor Gaynor within...
...still alive and in the best of condition. Also contained in the exhibit are "Galileo," the smallest book printed from movable type, and the "Rubaiyat of Omar Khaiyam," the tiniest volume ever printed. The latter, about half the size of a dime, was produced by a special photo-reducing process; the only other extant copy of it resides in the British Museum...
...obtained this photo from a British pilot (name forgotten) in November 1918 when stationed at the Toul airdrome as a flight commander of the U. S. Pursuit Squadron No. 141 (equipped with type XIII Spads) under command of Princeton's famed "Hobey" Baker...
...process, in commercial use since 1929, named for Clare Finlay, a London color photography pioneer. O. J. Jordan of Washington, D. C. who made the TIME photograph, explains that the Finlay process renders color photography almost as simple as ordinary black & white photography. The Roosevelt picture was taken with Photo flash bulbs for lighting, with an exposure of about 1/50 sec. The colors were recorded on one special sensitized plate, placed behind a taking screen made up of hundreds of thousands of infinitesimal tri-color (red, green, blue-violet) filters which absorb part of the light and transmit the remainder...
