angry tapir writes "I recently had the opportunity to sit down with Charles (Charlie) Pellerin, who was NASA's director of astrophysics when the Hubble Space Telescope launched with its seemingly fatally flawed optical system. Pellerin went on to head up the servicing mission that finally fixed the telescope and for that was awarded NASA's highest honor, a Distinguished Service Medal. Since Hubble he has done a lot of thinking about the problems that led up to the error and how organizations can best avoid making similar mistakes."
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.
