...Solar Heating. To Becklin and Westphal, this consistent temperature behavior suggests that the comet generated no heat, but was warmed entirely by solar radiation. Another set of observa tions seemed to bear them out: temperatures of the comet's head and tail were always identical. If the comet supplied some of its own heat, its head, or nucleus, should have been warmer...
...universes might it be possible to detect a Faustian galaxy, which would absorb energy instead of radiating it in familiar galactic fashion. The search for such a galaxy, Stannard suggests, could be made by a telescope equipped with a sensitive thermal device. If the device suddenly began radiating heat, the telescope almost certainly would be pinpointing a heat-absorbing Faustian galaxy, otherwise invisible because it would also be absorbing rather than emitting light...
When it hurtled back into the atmosphere, Apollo reached a speed of 19,000 m.p.h. At an altitude of 218,000 feet, small control rockets were fired, shifting Apollo so that its contoured heat shield provided a small amount of lift. As a result, Apollo literally bounced off the thickening atmosphere like a flat stone skipping across water; it rose to 264,500 feet before beginning to fall once more. The maneuver not only sliced some 3,000 m.p.h. off the craft's dangerously high descent speed but enabled its heat shield to cool before the final plunge through...
...country's top test drivers and endurance racers, most notably with the 200 m.p.h. Ford Mark Us, in which he won this year's Daytona 24 Hour Continental and Sebring twelve-hour races and barely missed winning the 24 hours of Le Mans on a dead-heat technicality; of injuries suffered when a new grand touring Ford prototype that he was testing went out of control on a curve at 100 m.p.h.; in Riverside, Calif...
Anthropologist C. Loring Brace waded in with the observation that humans who now wear the least clothing have the least hair on their bodies; those who wear the most have the greatest amount of hair. Brace believes that man lost his hair by hunting in the noon heat of tropical days; natural selection favored the relatively hairless hunters, whose bodies were best equipped to dissipate heat. This happened more than half a million years ago, says Brace, or roughly 400,000 years before man developed clothing...
