Knowledge of controllable grain sise which is vital evidence in metallurgical problems has been made canity available through the grain sise comparator developed by F. C. Hull of the Westinghouse Research Laboratories. It provifles for counting the grains in a certain area or estimating their extent by comparison with standard photographs
Migration of radioactive Cu through the internal structure of metals is followed by means af a Geiger counter by James K. Stanley, Westinghouse Research Laboratories. Migration of carbon is believed to be one reason why steelagesand becomes brittle
Shooting off a popgun can transform water droplets to snowr Sitilden expansion of air from within the popgun causes a momentary drop in temperature severe enough to produce ice nuclei. These nuclei then begin growing at the expense of tlve supercooled tvater droplets in the cold-chamber cloud. Within a few seconds the cloud "dries up" and the nuclei become snow crystals
