I apologize if this is coming to you twice; the first time I sent this, it seemed to vanish.
I'm codeveloping an AP Calculus course to be delivered by distance learning. We would like to include a short (five minutes?) video clip of someone famous and heroic (David Robinson? and astronaut?) discussing how calculus has changed his or her life (for the better, of course). Does anyone on this list know of any such video? Please send me details if you do. Thank you for your time.
