Tedd,

George Gamow wrote a delightful
book called 

        "One Two Three Infinity"

that appeared in the Mentor series 
way back.  Rick said:

I would be more radical. Reckoning 
with various sorts of infinity is 
also for the home the office and the 
tennis court.  With the tennis 
racquet puzzle we met every number in 
Gamow's title; and the road to to 
little old 3 went via infinity. 

Cheers
