I have (perhaps unwisely!) decided to do a 'Pecha Kucha' on imagination .... or at least imaginary numbers. The audience are all engineers with hazy recollection of undergrad maths. If you are not familiar with Pecha Kucha, then its worth checking Youtube and doing some googling. Simplistically the concept is to share understanding of something using 20 slides. Each slide should convey as much as possible with as few words as possible, with the message limited to 20 seconds! So, what is the most interesting thing about the imaginary number 'i' that you can think of, and how can it most simply be conveyed using Mathematica 7 in Slide presentation form? I've started with the notion of polynomial roots, de Moivre, reflections etc. but would appreciate a wider view. R
