Why do the SICP Exercise?

I decide to do the exercises of the book of SICP, and put them on javaeye.

Before this decision, I saw a person who had spent one whole year on reading the SICP, and publised his thinkings and solutions of the exercises on his blog. It's him who inspired me to make this program.

During the passed month , I just readed the book without doing exercises. Now, I find that the model of thinking how to program is still in c/c++/Java's style. So I think I must make a change.

Okay, let's go and do it now.
