-summary: I bought "The Little Schemer"
----
-
-Yesterday, I took a trip to the MIT Press Bookstore and picked up a
-copy of
-[The Little Schemer](http://mitpress.mit.edu/books/little-schemer). I’ve
-only spent a few hours reading and coding along with it, but I’ve had
-a lot of fun. The following is a mini-review based on my experience
-thus far.
-
-“The Little Schemer” teaches you to think recursively using an
-interesting and comedic writing style and the Scheme programming
-language. While Scheme is the language of choice, the real goal is to
-teach you problem solving rather than the details of a specific
-language. The book starts off simple, explaining what atoms, lists,
-and S-expressions are. Rather than providing the definition and then
-showing examples, it first gives examples in the form of a question
-and answer.
-
-Example:
-
-> Is it true that this an atom?
->
-> **atom**
->
-> Yes, because **atom** is a string of characters beginning with a
-> letter.
-
-From the examples given, a definition is created. In later examples, a
-Scheme procedure is written that produces the correct answers for all
-of the questions stated before it. It’s fun to build the procedure,
-verify that it works for all cases, and compare your implementation
-with the book’s.
-
-“The Little Schemer” defines ten commandments that are essential to
-correctly solving the problems in the book. Some commandments are
-first given in an incomplete form, and expanded later when a greater
-level of understanding has been achieved. The problems that you solve
-reinforce the commandments. You might notice that you start writing
-procedures without thinking much about it, much like the muscle memory
-earned from using Emacs a lot. Gerald J. Sussman was right when he
-said that this book “can perform the same service that Hanon’s finger
-exercises or Czerny’s piano studies perform for the student of the
-piano.” I have no idea who Hanon and Czerny are, but I get it. For the
-drummers out there, you could liken this book to
-[Stick Control](http://www.amazon.com/Stick-Control-For-Snare-Drummer/dp/1892764040).
-
-The writing style is very informal, comedic, and food themed. Page 13
-has a space reserved for jelly stains, and page 52 tells you to “go
-cons a piece of cake onto your mouth.” I have laughed a number of
-times while reading. Oh, and let’s not forget about the cute elephant
-drawings. This is definitely not your average boring, dry computer
-science book. If you are interested in a unique and enjoyable learning
-experience, then I highly recommend reading “The Little Schemer”.
