Float zone refining of silicon, 1950s. Physical research chemist at DuPont's Experimental Station using an analog computer to determine the temperature characteristics of a bar of silicon. It is undergoing refinement by the floating zone technique which involves gradual moving of the silicon through a furnace so that a small part of the bar is molten at a time.
