At a dinner party a few years ago, I had the good fortune to be seated next to a guy from JPL, Jet Propulsion Laboratory, who was leading a team of scientists who were studying the interior of glaciers.

Since they disintegrate from the inside, it’s necessary for us to know more than their area, which we’ve been able to determine from satellite imagery for half a century, and establish their health in three dimensions.

He wasn’t a “happy camper.”
