Education costs money. Ignorance costs more.
Hey Alan. I've just spent 13 mins 23 seconds watching and listening to your slide show. I really benefitted from a) the non-technical approach and b) its application to education. I'm really beginning to see its usefulness. Hoep you got a good response in Edinburgh (did you deliver it as a lecture there?). Would be good to catch up to chat about it when you're back.
