Essential Physics

In this deeply original book, science writer Anil Ananthaswamy sets out in search of the telescopes and detectors that promise to answer the biggest questions in modern cosmology. Why is the universe expanding at an ever faster rate? What is the nature of the "dark matter" that makes up almost a quarter of the universe? Why does the universe appear fine-tuned for life? Are there others besides our own?

Most of us are clueless when it comes to the physics that makes our modern world so convenient. What's the simple science behind motion sensors, touch screens, and toasters? How do we glide through tolls using an E-ZPass or find our way to new places using GPS? In The Physics of Everyday Things, James Kakalios takes us on an amazing journey into the subatomic marvels that underlie so much of what we use and take for granted.

Time is one of the great mysteries of the universe. In this fascinating volume, NASA astronomer and educator Sten Odenwald brings to life the philosophical and scientific conundrums about time in simple and accessible language.

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 are some of the most fascinating phenomena in the natural universe. In this beautiful pocket volume, Odenwald explores the science behind black holes in simple and accessible language. He explains what black holes are, how they come into existence, and how they affect the universe around us. Taking into consideration subjects such as gravity, quantum mechanics, the holographic principle and thermodynamics along the way, The Essential Book of Black Holes provides the perfect starting point for anyone interested in the subject.

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?

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".
