...target was School Superintendent Benjamin C. Willis, 61, who has long resisted Negro pressure, exerted through the board of education, to take drastic measures to mitigate segregation. Early in October, protesting that the board was moving into his area of authority, he resigned...
Even before last June's confirming flight, other astronomers searched for the X-ray source with every possible technique, but they could not identify their target. Theories, however, are plentiful. Some astronomers believe that the X rays come from a very large concentration of stars near the center of the Milky Way galaxy that are otherwise invisible because of obscuring dust. Professor Bruno Rossi, M.I.T.'s cosmic-ray expert, doubts this idea because those stars would have to be producing more than 1,000 times as many X rays...
...left hand the blindfolded subject holds a tiller by which he can swing the sound beam, searching for test objects-small wires, lengths of pipe, pieces of cloth-hung at random from the chamber's roof. When the beam hits a target, an echo comes back, and from the character of that echo an experienced listener can tell an amazing amount about the target...
...frequencies in the sound pulses, a formula that Lockheed copied from the porpoises. Small objects such as wires do not reflect the longer sound waves of the lower frequencies. The echoes that they send back are predominantly high-pitched, and a listener quickly learns to judge target size by the tone of the echo. Once he knows the size of an object, he can tell its distance by the loudness of the echo. Judging a target's material is a more subtle job, but in general, such hard materials as metal and glass send back a clear buzz, while...
