div> This book provides an interesting mixture of mathematical questions, puzzles & riddles, and explanatory information regarding various topics. Do not be reluctant to enjoy the mathematics section, because all questions have answers and solutions - you can have the satisfaction of understanding the detailed solutions. This is true for all three sections of the book. Scientists use various instruments in studying the subjects of their research. Mathematicians also employ an instrument for their analysis and research. Their instrument, however, is not a physical device. The mathematician's significant resource is an intellectual instrument, having the functionality of reason and inspiration. This instrument cannot be seen. But, also, no one has ever seen a geometric point, or a number. You have seen the symbol that is written to represent a number, but the number itself has no physical existence that can be experienced with any of our five senses that were given to us by the Creating, Sustaining, and Redeeming God of all Reality. Mathematicians work with ideas, and so it is appropriate that their significant instrument is mental, because the very substance and essence of mathematics exists only in the human imagination. In the brevity of this book, you can only experience a few snapshots or portraits of the materialization of some thoughts and ideas relating to the reality of our universe. It is my desire that you (the reader) will determine this kaleidoscope of ideas to be an incentive to recognize and enjoy some of the abundant treasures of our existence.
