These booklets appear to be well thought out and useful for formal or informal teaching in schools, or in university extension programs for schoolchildren. The slides included with Volume I are very well selected.
The study of fractals is a topic that seems to be developing an important role as a way to motivate students to become interested in mathematics or physics. The material presented in these booklets is ideal for informal teaching in that while it motivates students and touches on topics taught in formal classes, students exposed to this material will gain breadth, but will not be bored later in their regular classes.
