[BITList] Beauty of mathematics

[HUGH]

John,

These striking arithmetical results are often at the root of mind tricks, 
much disguised by mumbo jumbo.

I am presently struggling with a small group in our church who are 
themselves struggling with the necessity to resolve a problem with one of 
the three heating boilers.  Their main problem is that (a) they haven't a 
clue about boilers (one of them thinks they are made of wood), and (b) they 
are deaf to my advice.  A gem of advice proffered by one of them the other 
day is that some modern boilers are 150% efficient, and we should buy one. 
He got that from an expert.  So I'll have another look at your pps show to 
see how to get 150% efficiency.

Hugh.
