This was a really easy read that gave clear explanations to the topics I wanted. One thing that really bugged me was how overly visually stimulating it could be a times. Sometimes, on one page my eyes would be thrown it five different directions because of graphs or questions and comments posted on the side of the page. While some of what was there made it much more interesting to read, it could become too much. In the end, this was a book that was easy to understand and gave plenty of examples in both modern and older times.
