The book improves upon the original posts in several ways:
- I have re-edited the entire text (with professional help) to make it flow more smoothly as a book, and to improve correctness and clarity.
- I have added several professionally-created diagrams to illustrate key points.
- I have added a longer prologue and conclusion, and (for the print edition) an extensive index.
- The visual design of the book interior is to a much higher standard than the original posts.
