Robert Taylor has an MSc in Mathematics, however his real interest in arithmetic did not stem from university. He learned philosophy and a new theory of number from his father, Doctor Stephen Taylor, and has worked on this most of his life.
This book describes how Circlemaths originated, and is replete with philosophy, which runs far deeper than mere calculation. Not a "how to calculate" book, but a book relating philosophy to number. Arithmetic and philosophy become inextricably intertwined in this approach to number.
For children and adults alike, the foundations of counting are explored in detail. The history of number as it emerges from the human mind. Bases are explored along with ways to do multi-base arithmetic, aimed at introducing fundamental concepts to assist with rapid mental calculation, developed further in other books.
After reading this book you may find your ability to mentally subtract has increased enormously. You will calculate faster. Also you will discover a way to do long division without needing to know any of the "terrible times tables" at all, a way so simple you can successfully teach it to a five year old. The book is written in an easy to read manner for parents, children and teachers.
Doctor Taylor's book on natural birth is not primarily focused on new physical positions or breathing techniques. These are not the problem. Birth is matched by a highly intricate and very delicate psychological mechanism which modern medicine overlooks to its detriment. Understanding that mechanism is the key to correcting it. This includes the theory and practice for obtaining a natural birth.
