  1. Well said, Brad! Whenever I want to put the spotlight on some mathematical concept that is puzzling me, Khan Academy is my first port of call. I heartily endorse the tremendous work done by Sal Khan and his assistants.
    By the way, the following quote is something I wish I could have been exposed to in 1966 as I chose to drop mathematics as an undergraduate:
    “I advise my students to listen carefully the moment they decide to take no more mathematics courses. They might be able to hear the sound of closing doors.”
    James Caballero, in ‘Everybody a mathematician?’,CAIP Quarterly 2 (Fall, 1989).
    The good news is, it is never too late and the doors opened by Mike Hockney and his colleagues (using ontological mathematics) are the proverbial ‘doors of perception’ (apologies to Aldous Huxley). And if the door won’t open easily then it is worth paying a visit to Khan Academy.
