...track the slow-moving presidential car until it got past him, then got off three shots in about five seconds. After he fired, Oswald ran toward the center of the building and down an aisle to a stair well door. There, behind a few boxes of books, he thrust his carbine. He then hurried down the steps - and perhaps because he heard the oncoming foot steps of the motorcycle cop and Superintendent Truly - he ducked quickly into the lunch room...
...Hurt. Chicago's "Papa Bear" is 68 now; his hair is taking a permanent leave of absence, and his spectacles are as thick as the bottoms of shot glasses. But he has not mellowed a whit. Teeth clenched, hands thrust deep into his overcoat pockets, he follows the ball up and down the field bellowing at his players, badgering officials, blatantly coaching from the sideline. Trying to lend moral assistance to a Bear field-goal attempt, he once booted a 240-lb. guard right off the bench. Another time, he curtly ordered a rookie:"Taylor...
...Bootstraps. Designed to hurl more than a ton of instrument payloads all the way to the moon, the 28½-ft. Centaur generates 30,000 Ibs. of thrust with its two restartable Pratt & Whitney engines. The hydrogen fuel they burn has been the key-and the curse-of the Centaur system from the time it was born on engineers' drawing boards. As early as 1909, U.S. Rocket Pioneer Robert Goddard noted that hydrogen (in liquid form, known as LH.,) might prove to be the optimum chemical rocket fuel. Its light molecular weight, less than half that of standard liquid...
...Pratt & Whitney engineers set out to develop the Centaur's engines, they boldly planned to turn that touchy temperament to their advantage. In the final product, frigid LH2 does two jobs as it courses toward ignition. First, it is pumped through an outer jacket where it cools the thrust chamber's fierce 6,000° heat, and in the process vaporizes itself for ultimate burning. But before it reaches the chamber, the gas is expanding fast enough to spin an auxiliary turbine, which pumps more fuel and oxidizer into the cooling jacket. Thus the LH2 practically lifts itself...
...thesis is that the whole of civilized history can be reduced to the confrontation of the East and West, with "alternating phases of Oriental and Western ascendancy." The West set the pendulum in motion with the capture of Troy in about 1250 B.C., which launched the Greeks' thrust into Asia Minor. Since that time, the East has rebounded with two long periods of ascendancy-one following the Persian conquests under Darius (522 B.C.), the other from roughly A.D. 400 to 1000, when Buddhism was sweeping Asia and Europe was plunged in the Dark Ages. The West was ascendant from...
