I found the cartoon approach of this book so compelling and its story so endearing that I recommend that every teacher of introductory physics, in both high school and college, consider using it. -American Journal of Physics This is a perfect introduction to four key physics concepts-law of action and reaction, force and motion, momentum, and energy-especially for fans of anime and manga. <-School Library Journal Overall, we found the books absolutely amazing for teaching complex ideas and theories to people of nearly any age. <-Physics Today
