Essential Physics

Quantum physics is notable for its brazen defiance of common sense. (Think of Schrödinger's Cat, famously both dead and alive.) An especially rigorous form of quantum contradiction occurs in experiments with entangled particles. Our common assumption is that objects have properties whether or not anyone is observing them, and the measurement of one can't affect the other. Quantum entanglement rejects this assumption, offering impeccable reasoning and irrefutable evidence of the opposite. Is quantum entanglement mystical, or just mystifying?

When asked to explain Relativity simply, Albert Einstein himself once joked, “Put your hand on a hot stove for a minute, and it seems like an hour. Sit with a pretty girl for an hour, and it seems like a minute. That's Relativity.” But when most normal people without advanced training attempt to study the subject seriously, they’re quickly weighed down by the mathematics…

E=mc2: It may be Einstein’s most well-known contribution to modern science, but how many people understand the thought process or physics behind this famous equation? In this collection of his seven most important essays on physics, Einstein guides the listener step-by-step through the many layers of scientific theory that formed a starting point for his discoveries.

Black holes, predicted by Albert Einstein's general theory of relativity more than a century ago, have long intrigued scientists and the public with their bizarre and fantastical properties. Although Einstein understood that black holes were mathematical solutions to his equations, he never accepted their physical reality - a viewpoint many shared. After introducing the basics of the special and general theories of relativity, this book describes black holes both as astrophysical objects and theoretical "laboratories".
