NASA scientists at the same time revealed a previously undisclosed problem during the flight: the "Pogo Effect," an up-and-down, pogo-stick-like vibration that was also detected during Saturn 5's initial flight. The effect, caused by the synchronous pulsing of all five first-stage F-1 engines at their natural resonant frequency, produced a vibrational force of three-tenths Gs during the first flight-enough to jar astronauts had they been aboard, but not enough to cause any serious difficulty. On the April shot, however, the Pogo Effect reached a force of seven-tenths...
Helium into LOX. To rid Saturn of Pogo, scientists may inject small amounts of liquid helium into the liquid oxygen (LOX) lines of two of the engines, damping the sloshing of the LOX and thus changing the resonant frequencies of the engines. Or they may place gas-filled cavities beneath the LOX lines of two engines to act as shock absorbers. Either solution would cause two engines to pulse at different frequencies from the others, preventing a five-engine resonant buildup of the Pogo Effect...
Just as sure as presidential candidates crop up every four years, so is Cartoonist Walt Kelly sure to needle them in his comic strip, Pogo. He is off to a fast start this year. During the New Hampshire primary campaign, he sketched Romney, Rockefeller and Nixon as windup dolls running off haphazardly in all directions-and in the case of Romney, backward. Last week it was Lyndon Johnson's turn in the guise of a booted, bulbous-nosed Texas longhorn that horns in on a picture-taking session. "You gittin' my good side, oF buddy?" he inquires...
...commencement-time party in the spring is famous in Cambridge, as is the "young people's party" they give in the winter for sons and daughters of their friends. Galbraith's dancing style, which consists mostly of hopping up and down in place, has been described as the "pogo-stick stomp." The Galbraiths have three sons of their own: John Alan, 26 (Harvard '63), a clerk for California Supreme Court Justice Stanley Mosk; Peter, 17, an eleventh-grader at Boston's Commonwealth School; James, 16, a sophomore at Andover. A fourth, Douglas, died of leukemia in 1950 at seven...
...gross misinterpretation of research on TV viewing. I have seen no evidence to support this argument; in fact, the data seem to show that many highly intelligent and creative individuals, both children and adults, watch TV to degrees that the TIME article would find "excessive." Excessive anything-smoking, drinking, pogo-stick jumping-can be indicative of personal problems. Excessive TV viewing may also be indicative of great interest, and serves as the greatest educator since the invention of the Latin grammar school...
