I have Sir Ken's MP3 audio file down on the hard drive to challenge my colleagues with BUT...

I must insist that Maths is a highly creative subject that I find involves both the left and right brain (build your castle in the air then knock it down with logical objections, then re-build it to survive the objection, repeat). I, like many maths people, also find that movement is essential: I have to walk to do Maths, others sing, and some have to dance. Google Jacques Hadamard for more on the psychology of mathematical invention.
