Since Roman days the Rhine valley has always had great strategic importance as one of the main arteries in Europe. During the Middle Ages more castles were built within its narrow confines than in any other valley in the world, and today the remains of these once proud structures form an integral part of the Rhine landscape, adding greatly to the romantic atmosphere which has made it famous. "Castles on the Rhine" is the perfect book for both the traveler and the historian. It not only contains tons of photos, but the book goes through a brief historical summary of the area, then gives an ...

This book describes the history, development, and science behind one of the biggest breakthroughs of this century: The Spinning Charged Ring Atomic Model. The model is based entirely on classical physics, and therefore doesn't require Quantum Theory, hundreds of sub-atomic particles, imaginary forces, Heisenberg Uncertainty, or dark energy to explain its operation. Every part of the spinning-ring model has a cause-and-effect basis in the theories of electromagnetism derived from Maxwell's Equations. Electromagnetism is the only force required to explain its construct and operation. 1. The ...

This is a Science-Technology-Engineering-Math (STEM) book. The first half of this book explains how GPS works in easy-to-understand language. The second half of this book explains how different industries use GPS: Search and Rescue, Railroads, Aircraft, Ships, etc. The book concludes with a set of quiz questions over the material. The book delves into technical details, such as number of satellites and their orbits, how distance to a satellite is calculated, etc., but does not overwhelm the reader with math or physics. It is appropriate for middle-school age student through adult.

As they unravel clues, the mystery grows as almost every camper becomes a...

This book provides a correlation of geological, archaeological and historical records with the Bible presented in a new perspective. Why a new perspective? This implies that previous attempts at correlating these items have not provided satisfactory answers to all the factors involved, and from my own experience, this is correct. Most Bible teaching does not include correlation of historical information from other nations with the historical events of the Israelites, and so important information is not conveyed to the student. Teachers should not be faulted for this because this type of ...
