daltec writes "The $250,000 American Helicopter Society Igor I. Sikorsky Human Powered Helicopter Competition prize, unclaimed since 1980, is now closer than ever to being won. With flights up to ten feet in altitude and lasting over 65 seconds, the prize's strict requirements (thought by many to be impossible to satisfy) have all been met — but not on the same flight. Two teams — AeroVelo in Canada and Gamera II at the University of Maryland — are tantalizingly close to claiming the prize. The Gamera team will be making its latest attempt this weekend."
Thus mathematics may be defined as the subject in which we never know
what we are talking about, nor whether what we are saying is true.
