Making a Molehill Out of Mount Everest - The Scientist - Magazine of the Life Sciences
Abstract
When I was growing up, there were perhaps only three facts of geography I knew for sure: the equator was exactly 25,000 miles long, heaven was located just above the Van Allen radiation belt, and Mount Everest was the highest mountain in the world. These were scientific facts of the first order, known to all parochial school children, and inculcated through repetition and regular use of the chart and pointer by Sister Mary Geography. It is a sign of the faithless age in which we live that no one will really commit himself on precisely how long the equator is, and that contemporary theologians tend to blush at the notion of an astrophysical heaven. And now, science has dashed the last of my childhood geographical truths: Mount Everest may have fallen from its lofty heights. Using laser beams, satellite linkups and other high-tech items, a team of American scientists has concluded that K-2, a Himalayan peak in northern Kashmir near the China border, may be 36 feet taller than Old Reliable. That makes it at least 29,064 feet (and possibly as much as 29,228 feet) above sea level. Everest, according to conventional measurements, is a mere 29,028 feet.
