//  A friend experimented with different top-hats on an 8' vertical to 
find out which one made the most field strength compared with no top-hat. 
   There was virtually no difference in field strength. 
--  "I know that most men, including those who are at ease with problems 
of the greatest complexity, can seldom accept even the simplest and most 
obvious truth if it be such as would oblige them to admit the falsity of 
conclusions which they had delighted in explaining to colleagues, which 
they had proudly taught to others, and which they had woven, thread by 
thread, into the fabric of their lives." -  L. Tolstoy - (1828-1910)
