    The "Barometer Fable" mentioned by Frank Reed is somewhat older than the reference cited...
    Maybe Alexander Callandra can be credited with publishing the "parable", but 
    it was a topic of lively conversation in one of my physics classes at the 
    University of Michigan circa 1958.  Unfortunately this hints at my age, but 
    my memory has often been refreshed on this fable during several discussions 
    since.
    My recollection didn't include a recalcitrant student, but simply a wild 
    discussion of the various possibilities.
