A Dancing Wu Li Master?

Last Thursday night training session of the year, so I was mostly focussed on the going to the pub afterwards. I did manage give a little educational chat to the teenagers about physics/conservation of momentum (what do they teach them in schools nowadays!?). The parting shot from one of them was to ask me to explain quantum mechanics to them....a bit more tricky to find examples relevant to kung fu for that one. Perhaps I need to re-read this?
