title: The Little Schemer - Where to start?
body: <p>I just cracked open The Little Schemer, and I feel like I'm missing something.  </p>
  
  <p>The first question asks "Is it true that this is an atom?", but I do not see any definition of what an atom is.  I suppose I can derive what an atom is by the answers to the questions, but then it goes on to ask what is the car of l, and what is the cdr of l, and I have no idea what is being asked.  </p>
  
  <p>Is the purpose of the book to discover what the questions mean by reading the answers, or is there some basic knowledge that I need before I tackle this book?  If the latter, can someone point me to where I might acquire that basic knowledge?</p>
