A book of puzzles, lateral thinking problems, conundrums, magic, and interesting arithmetical tricks sometimes progressing to and using extremely basic mathematical and scientific principles. The author focuses particularly on situations and solutions to problems that at first glance appear to be incorrect, paradoxical, or even impossible. Often those with a love for problems and puzzles do not always readily understand the solutions. However, audiences confounded by a problem are generally delighted to have the answer given and explained in a straightforward and logical manner. In this book that means occasionally including a simple mathematical solution, even though sometimes, some of these explanations didn't appear to be what we readily understand to be mathematics!

The Battle of the Bulge was the largest land battle in U.S. history, a battle that cost the United States 20,000 lives and stopped the last German offensive of World War II. The authors, both residents of Helena, Montana, studied the history of this battle and walked the critical sectors of the battlefield, examining examples of American heroism and looking for evidence of involvement by Montanans. Their objective was to better understand this significant battle and how our soldiers managed to stop an enemy steamroller, overcoming their fears while outnumbered more than three-to-one. This book examines the eleven critical junctures of the battle and includes personal stories of Montana veterans.

Intended for those new to clinical supervision or experienced.
