In our case, the group theory is a kind of banter, a chance to say CAIN (closure associativity inverse neutral) and wink at someone, because you both went to that same summer of code or whatever barcamp. I've noticed the MBA types are tracked away from sounding too much like computer scientists, which is where this curriculum is refreshing. Most of our students are already employed (an educated guess) and are using some of their free time to invest in new skills. This is the demographic with the best access. Nursing homes, penitentiaries, and high schools, tend to lag, though I could see those numbers picking up in more liberal countries like Sweden. But then who speaks Swedish in California... distance education gets confusing. One of my latest live gigs was a room full of PhDs in Baltimore. No one there needed any more "academic credit" and yet they all wanted to learn Python. They weren't from the same specialties always (quite a few were in instrumentation for Hubble type spacecraft). Putting a group theory spin on it, having a few polyhedrons (literally, in my carry-on) helped lighten the atmosphere as I was clearly not going to talk down to them, nor bore them with too many examples about money (a common mistake of business class teachers, when confronted with a science-minded audience (hence names like PermCell and PermDNA)). > > That's perfect Ed.

I'd let PeeWee Herman teach Python if he wanted, though I think some of his talking furniture items might be better at it. Kirby
