When a person goes from sea level up a mountain his weight goes down because he is farther from the
center of mass of earth. But, since air pressure is lower, there is less buoyancy in air, so this adds to the
measured weight. What are the relative sizes of these effects? And, how much does buoyancy lessen the
weight of a person at sea level?
