...Britain, India, Nepal and the United Nations. Tenzing dug a hollow in the snow and filled it with Buddhist offerings: a few sweets, a chocolate bar and some cookies. Hillary dug a second hole and buried a crucifix. The two nibbled on some mint cake and, aware that their oxygen supplies were limited, began their descent 15 min. after reaching their goal...
...runner's stride is not perfectly efficient. Ankles waste energy?much more, it turns out, than Pistorius' J-shaped blades. He can run just as fast using less oxygen than his competitors (one describes the sound Pistorius makes as like being chased by a giant pair of scissors). On Jan. 14, following the findings of the researcher who evaluated him, the IAAF disqualified Pistorius from Olympic competition. He is expected to appeal, arguing that the science of advantage is not that simple. Tom Hanks is interested in his life story. No matter what happens next, Pistorius is changing the nature...
...completely inadequate for climbing at high altitude in the Himalayas. Even though I had pretty good resistance to cold in my feet, that first trip I definitely had cold feet. But we still made a lot of new summits and we really did extremely well. We weren't using oxygen that trip. The highest mountain we climbed was just over 22,000 feet...
...realized that that must be the top. It's not a really sharp summit - the sort you hold your hands around. It's a summit that you can stand on reasonably comfortably. Six or eight people could probably all stand together. A nice summit. I took my oxygen off and took photographs down all the leading ridges, just to make sure I had plenty of evidence that we had actually got to the top. Then I looked across at Makalu, and I can remember assessing the routes up Makalu, which hadn't yet been climbed. I began mentally working...
What researchers found was a stretch of a few hundred thousand years during which foraminifera shells were unusually rich in oxygen-18, suggesting the presence of glaciers. Though changes in ocean temperature can also alter the oxygen balance, sea-bottom temperatures don't vary much no matter what's happening up top, yet the bottom-dwelling foraminifera still exhibited an oxygen imbalance, implying that the ice effect was more likely. Nobody can explain how you can have glaciers in a superhot world. But then, nobody can really explain how the world got quite that hot in the first place...
