This book is an experiment in a new way to put together an edited collection of writings. Chapter 10 of the book contains a brief introduction to a number of topics that are suitable for making into additional chapters. Potential authors are encouraged to contact David Moursund (firstname.lastname@example.org) or Robert Sylwester (email@example.com) about submitting a chapter based on Chapter 10 ideas or other ideas of their own choice. The book will ?grow? as new chapters are integrated in.
