Free Kindle Book Downloads from Amazon

Ok, you can call me a nerd, but I used to be a science teacher, and this book sounds really interesting to me.  It is normally $20, but is being offered as a free Kindle download here.  That makes it even more exciting to me. =)  If this one doesn't interest you, there are many, many free Kindle books to choose from.  You can check out the bestsellers list and choose the ones you like.  If you don't have a Kindle, you can download a free Kindle app for a variety of computers/cell phones.
