...should receive a few more rays than the back of the planet, just as a child riding a carousel in the rain should be struck by more drops in front than in back. This small daily variation in the cosmic rays has actually been observed, so Dr. Compton agrees they must come from the remotest depths of space. What is their scientific importance? 1) A cosmic ray impact led to the discovery of the positive electron, a fundamental particle of matter. 2) The geographic distribution of the rays facilitates study of Earth's magnetic field. 3) For laboratory work...
...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...
...Children. He has one class a day, at 8 a. m., after which he works in his office, which has a black steel desk, cream walls, tan curtains, grey rug, a cosmic-ray counter clicking away in a corner; or in the laboratories just outside where he has $50,000 worth of equipment for his own researches. He does much of his own experimental work, and his assistants admire his manual skill. He is reputed the best scientific glassblower in the Midwest...

...past few years," he declared, "there have been three outstanding cosmetic procedures that have been dangerous to the general public: Removal of superfluous hair by X-ray which has resulted in scars and cancer; the use of certain dyes on the eyelashes and eye-brows which has caused blindness and death; and the use of thallium acetate in creams to remove superfluous hairs which has caused serious illness and death...
