G'Day Paul, Your statement to the group is worryingly inaccurate inasmuch as you have not "asked [me] twice" at all. You cannot claim to have asked anyone something if you have received no response whatever from that person to the question that you only think that you have posed. Since I have now read and responded to your posting, you can claim to have asked me once. And, in immediate response to your request, I would be pleased for you to post the puzzle. You also seem to be a little confused regarding doctoral theses, for otherwise what point were you trying to make by directing the following comment at Robert: "I have indicated previously that your comments show a very poor understanding of basic physics (btw -- you still haven't favoured us with any information about your PhD or the subject of your doctoral thesis -- is it something of which you are not proud?" Best wishes, Neville.

To date he has not responded so I guess he doesn't see the matter as important. However I will wait till Monday next, and if prohibition has not arrived by then, I will post it.
