...same afternoon two student friends of the professor met him in the Yard and stopped to congratulate him on the blessed event. As they started to express their best wishes, the professor put up his hand as if to wave them away. "Oh, don't congratulate ME, boys," he said modestly. "My wife did it all by herself. Herself, with just the help of two Dunster House tutors...
...Condon had entered into a contract with a sensational magazine for a series of articles entitled "Jafsie Tells All". Today, as Bruno Richard Hauptmann nears the death chair, as the New Jersey court of pardons turns down his plea for a respite and as the public sithers in a wave of doubt and high-feeling, Governor Hoffman hurls the credulous and timely challenge-Condon has not told all And implication adds:-he knows far more than he has told and he is fleeing the country in fear...
Millikan's Photons. It seemed natural to Dr. Millikan that the cosmic rays were light rays or photons of enormously high frequency and short wave length. He concluded that they were the by-products of atom-building in interstellar space; that when light-weight atoms suddenly combined to form heavier ones, a slight excess of matter-like bricklayer's mortar scraped from the wall-was turned into high-frequency light according to the Einstein equation. To him this was a peculiarly satisfying interpretation as it bespoke "the Creator still...
...measurements of x-ray wave lengths convinced Compton that such rays, although a form of light, could act like bullets as well as waves. If on colliding with gas atoms they lost part of their energy as bullets, they should recoil as waves weaker in intensity and hence longer in wave length. In addition they should kick electrons out of the gas. With apparatus so sensitive that it measured one ten-millionth of the energy of a mosquito climbing an inch of screen, he showed that this was true. This "Compton effect" went far to explain photo-electricity...
...hurl a pellet at 6,000 ft. per sec. (three times the speed of a rifle bullet) but throw hundreds of minute shreds of copper, each able to penetrate nearly a millimetre of brass sheet. Pellets from detonators, directed into jars of water, shatter the jars by the pressure wave in the water. As evidence that modern high explosives are not to be tampered with, Dr. Robert Williams Wood of Johns Hopkins exhibited a lantern slide depicting the impression of an apple leaf driven into solid steel by guncotton, declared the detonation in a tube of nitroglycerin proceeds at four...
