Though we take light for granted, the world's greatest scientists have long puzzled over its nature, properties, and behavior. Its incredible speed, mysterious frequency, relationship to color, form of travel, and uncanny ability to reflect, refract, diffract, and be absorbed altogether make light the ever-elusive quarry of science's greatest hunters of knowledge and understanding. This is the enthralling account of their investigations and discoveries, their conclusive insights and ongoing questions, enhanced by full-color photographs and explanatory visual aids. If you thought you knew everything there is to know about light, think again and read on.

Mechanics is the branch of physics that deals with forces and movement. Aligned to the science curriculum, this stimulating volume explores topics such as measurement, mass and weight, falling objects, force and acceleration, stability and equilibrium, energy, vectors and scalars, work and power, loads and levers, inclines and friction, and pulleys and gears. Nine projects help readers grasp a key scientific principle, such as cheating the force of gravity, inertia, and centripetal force. The text includes a chapter on Nicolas Copernicus, who developed the heliocentric model of the universe. Colorful diagrams explain certain concepts and the workings of machines.

We often automatically equate heat with temperature to such a degree that we may not take the time to consider what heat really is. Heat refers to the energy that is transferred from one body to another that is at a lower temperature. This transfer occurs often without us knowing it, but it is ever-present and crucial to all life. This volume examines the basics of heat and the related concept of temperature. Detailed diagrams help illustrate such concepts as specific heat capacity and latent heat. Clear text explains the difference between conduction, convection, and radiation, as well as emitters, absorbers, and more.

Understanding the basics of matter is a core piece of the science curriculum. This guide to matter is an interesting, colorful introduction to these concepts in the field of science, including bright photos, fun facts, and basic experiments that allow readers to have an informative and complete hands-on learning experience. Biographical information on some of the great minds in this field of science is also included, adding a detailed timeline and an interesting and engaging historical element to the text.

Two superpowers are in a race to recover and exploit alien technology. To compete with the rumored Russian retrieval of an alien spacecraft found deep in Siberia’s Lake Baikal, the U.S. government orders two Navy saturation divers to risk everything to help salvage a spacecraft that may not even exist. It is up to Jason Parker to make sure the divers return safely from the deepest man-dive ever, but he cannot guarantee mission success. That is up to luck, and the bravado and heroism of the Navy divers. The thriller Middle Waters was the beginning saga for diving scientist Jason Parker and Oceanographer Laura Smith. In Triangle, Russian submarines monitor diving preparations off the U.S. Gulf Coast, then attempt to sabotage the U.S. effort. What started as Russian curiosity, morphs into a deadly threat. To make matters worse, both the U.S. and Russia are targeting Parker and Smith for elimination, if the governments don’t get their way. As a result, Parker and Smith must struggle to survive at all odds, while trying to maintain world peace. With the Presidents of both the U.S. and Russia vying for supremacy, and the American President’s own staff warning of potential catastrophes, the balance of world power, and even world survival, may rest on a liaison between Parker, Smith and two mysterious men with most peculiar powers. One is a blind remote viewer, and the other is a Troll named Truman. The world will never be the same again.

When a great storm ravages his tropical island, the young dragon, Paradigm, is forced from the safety of his cave into the wide world he fears so much. But when he discovers that he is not the only dragon on the island his fate is set in motion, and he is swept into an adventure that will take him across the ocean and back again. But Paradigm is more than just a dragon, he is a Dream Dragon and his fate is linked with that of mankind. He must quickly learn to use his powers before a dark and terrible force can steal his soul and encase the entire world in eternal fear. 103,000 words

A pair of magnets, compass, flashlight bulb with insulated copper wire and alligator clips, glass prism, set of small mirrors, and balloons make up a set of clever learning tools when they're supplemented with this kit's 64-page book of fascinating science experiments. Kids discover fundamental principles of physics in the most effective way, which is learning by doing! They can introduce themselves to the relationship between magnetism and electricity, and they will discover the fundamental principles of light as it is diffracted through a prism to produce the entire color spectrum. They can perform experiments with air pressure, and they will gain understanding of how a compass points toward the Earth's magnetic North Pole. All these experiments (plus dozens more fun projects) are safe, easy-to-perform, and require only the included materials and objects that kids will readily find around the house. Here's a great introduction to the world of science, perfect for school or home. (Ages 7 and older)
