Physics is a system of models of nature according to which all phenomena are explained in terms of matter and force. Sound confusing? It doesn't have to be! Whether you need help with high school physics, need to review for a college physics class, or you're studying for the AP Physics Exam, this physics tutorial will help you understand the basics, such as Newton's Laws, the Law of Universal Gravitation, Kepler's Law and more.
During the last Ice Age, millions of large animals roamed the Earth, from wooly mammoths and giant sloths to cave lions and saber-toothed cats. But as the temperatures rose, three-quarters of these species died out. What happened? Can environmental changes alone really explain this mass extinction, or did humans - who at this very time were beginning their conquest of the planet - play a key role? To find out, researchers around the world are hunting and studying fossils in their search for answers to solve the mystery of the Ice Age giants.
Sniper: Bulletproof deconstructs and analyzes the little-known sniper events that have occurred when no other course of action was possible. The people who planned the takedowns, or pulled the trigger, share their techniques and bring to light the many factors that had to be considered in each mission: terrain, wind speed, temperature, elevation changes... all are critical to taking out targets considered bulletproof. A sniper has one chance, one breath, to rise to the occasion and save the day... if they miss, there may never be another opportunity. As these never told before stories unfold, the viewer also learns about the high-tech gear each sniper carries on their classified missions.
