...Paul Kenneth Hansma of Scottsdale, Ariz., "just seemed to drift into science," has built everything from a cloud chamber to a solar furnace to an electron accelerator. For a hobby he builds fountains, is now on his ninth. He studies with stereo earphones whispering light classical music to him. He will attend New College in Sarasota, Fla., move on to postgraduate research in physics. > Jacquelyn Faye Evans of Little Rock, Ark., made her achievements (straight A's) amid notably tense circumstances as one of the few Negro students to enter and stay at Little Rock's Hall High...
...that the line was hard to identify; its wave length showed that it came from ionized calcium atoms that have lost one electron. But where did this calcium come from? At the corona's temperature, 3,000,000º, calcium loses nearly all its 20 electrons and shows the loss by emitting a different kind of light. In the singly ionized state, calcium cannot exist above a comparatively frigid...
Loose particles of any material tend to travel in a straight line in a vacuum-a phenomenon that made television a reality by allowing the direction of electron beams to be precisely controlled in a vacuum tube. Liquids, from water to molten metals, boil and evaporate quickly at low temperatures in a vacuum and condense in an even film on any surface they strike. Thus industry has been able to lay thin metal grids in microcircuits (TIME, Feb. 7) and coat cheap plastic jewelry, auto trim or Christmas wrappings so that they look like gold or silver...
Last spring, Harvard and the AEC clashed over the administration of a $5 million a year grant for the operation of the Cambridge Electron Accelerator. The University contested the AEC's right to veto the employment application of any alien and to control all information released by the CEA to Soviet bloc scientists...
...Since mass is equivalent to energy, theoretical physicists like to measure the mass of a particle in electron volts. The mass of one electron at rest is .511 million electron volts...
