   Grin.. yup I'm using it daily now.  I keep telling my boss that for the heat   
   capacity of solids you just count atoms and then multiply by 3kT.  I'd really   
   like a table of heat capacity per volume... or per tensile strength.  I'd like   
   to know what    
   material to use for low heat capacity, but also strong.  (No Diamond or   
   Berrylium oxide..)
