   From time to time I come across statements that a domain expert has
   anywhere from 30,000 to 100,000 chunks of knowledge  (the figure varies
   according to the article).  How can anybody possibly come up with a 
   meaningful figure in this area?  How were these numbers calculated?  
   How much knowledge is in a chunk?  Does a chunk of domain expertise have
   very much meaning apart from chunks of common sense and world knowledge?
