The book is organized into three major sections with appropriate chapters in each.  In the first section, Gray shows how to effectively use TextMate’s project drawer for managing your work, explains TextMate’s Emacs-like keyboard shortcuts, and demonstrates the power of the find and replace features with regular expressions.  The second section shows TextMate’s strength in automating things you would normally type thereby saving you time and preventing typos. The final section explains how to write a language grammar yourself and provides a concrete example of such an implementation.

Despite being somewhat of a manual, the book is very readable with pictures, simple explanations, and some jokes tossed in.  Although the book isn’t a quick reference or a complete guide, it is very easy to find what you are looking for and contains a large amount of information along with examples.  If you are looking for a good reference book on the TextMate editor, definitely look into this one as it should contain everything you need.

The Manga Guide to Calculus starts off with a brief introduction and review of functions. It then jumps right into derivatives, what they mean, and how to compute them. Integration is then considered along Taylor series and partial differentiation. Throughout the story, the guide frequently references real world applications in economics, physics, and chemistry, and explains problems in these fields through the use of calculus. The author also includes probability, statistics, and trigonometry sections with calculus explanations. Exercises exist at the end of each section for you to complete and solutions are presented at end of the book.

There are a few downsides to the manga style of presentation. Formal proofs and definitions do not lend themselves well to be included, and the book is certainly lacking in this area. There may also be some areas which the reader will have to go over a few times to fully understand and see how the book goes from one idea to the next because of the amount of information being presented.

I would recommend this book to those who want a brief review of calculus, beginners who want context as to its uses, and to those who enjoy reading a good math book. This book is not for those who need a thorough review since many important topics are skipped such as limits, related rates, and volumes of rotations. Overall, Hiroyuki Kojima and Shin Togami did an excellent job in writing and illustrating the book respectively, which makes The Manga Guide to Calculus a very different and attractive learning tool.
