	an abstraction of it, actually
-----------------------------------------
CH# THEMES/TECHNIQUES or EX.   ABSTRACTION
==========================================
 1  Primitive Data               of world
 2  Procedures                   algorithm
     recursion over lists
 3  Abstract data types          data rep.
     (avoiding detail)
     recursion over numbers
 4  Relation between recursion
        in data & procedure
     other kinds of recursion
    Time efficiency
 5  Localizing names             algorithm
     polynomial arithmetic       data rep.
 6  Interactive programming
     input/output,side effects
     towers of hanoi, 8 queens
==========================================
 7  Avoiding having to write     algorithm
      same code twice: lambda
==========================================
 9  Time-Efficient access  
        and update to data
     vectors, matrices
11  Assignment and state        state info
     memoization 
------------------------------------------
	explain that abstraction is a way of focusing your attention
		like helping procedure idea
	if time will wrap up all this with Ch 12: OOP

	will use these concepts constantly in years to come
	the only thing you may not use right away is chapter 7, but that is
		the most beautiful part of the book
		will be more useful in the future when languages like Scheme
			are more widespread (already an industrial trend)
		will use them in certain other CE and CS courses (342, 472)
		this is nearly impossible to do in C or C++
