Just an additional note - people have been discussing some questions about the voting on the contest blog ( http://fqxi.org/community/forum/topic/1263 ) since Oct 5th, as quite a few essays suddenly dropped rapidly in position over the last 48 hours of voting. The organisers found some multiple voting had been going on, and removed the extra votes.
My essay stayed in the top 35 for two weeks from sept 20th, usually between positions 20 and 25, and was at 31 on Thursday 4th. Then in the last 24 hours of voting, it dropped more than 70 positions. Ah well! I don't know why that happened, but perhaps the positions up to the last 48 hours are more indicative. Anyway, I've had a very good response to my essay from colleagues, both in the ratings and more importantly in the discussions, particularly from Ben. The ratings should be in the margin of things anyway - the forum has been very good, and to me the event in general, and most of us have learned a lot from the exchange of ideas.
Best wishes to all, Jonathan
