Drew, your comments remind me of the story about the college physics teacher
who asked her students how they could determine the height of a building
using a barometer. One said that he would take an air pressure reading at
the ground floor, go up to the top of the building and take another and use
a formula, another said she would take the meter to the top of the building
and drop it, timing the fall and determining the height. The third thought
a bit out of the box. He said that he would find the person who designed
the building, tell that person that he had a great barometer he would give
him, if he told him how tall the building is (I guess you would have to
accept his expertise). Kim
