A renowned astrophysicist’s approachable introduction to Albert Einstein’s theory of relativity and its application in our daily lives. It is commonly assumed that if the Sun suddenly turned into a black hole, it would suck Earth and the rest of the planets into oblivion. Yet, as prominent author and astrophysicist Jeffrey Bennett points out, black holes don't suck. With that simple idea in mind, Bennett begins an entertaining introduction to Einstein's theories of relativity, describing the amazing phenomena readers would actually experience if they took a trip to a black hole. The theory of relativity reveals the speed of light as the cosmic speed limit, the mind-bending ideas of time dilation and curvature of spacetime, and what may be the most famous equation in history: E = mc2. Indeed, the theory of relativity shapes much of our modern understanding of the universe. It is not “just a theory”―every major prediction of relativity has been tested to exquisite precision, and its practical applications include the Global Positioning System (GPS). Amply illustrated and written in clear, accessible prose, Bennett's book proves anyone can grasp the basics of Einstein's ideas. His intuitive, nonmathematical approach gives a wide audience its first real taste of how relativity works and why it is so important to science and the way we view ourselves as human beings. “Well-written and uniquely readable . . . Bennett carefully avoids bombastic statements and “spectacularization” of the subject.” —Alberto Nicolis, Columbia University “I have read lots of introductions to relativity, but none is as clear and compelling as this one.” —Seth Shostak, Senior Astronomer, SETI Institute

Why do people buy? A behavioral economist explains the science of consumer behavior in “the most important business book to come out in years” (Michael F. Schein, author and columnist for Inc., Forbes, and Psychology Today). What Your Customer Wants and Can’t Tell You explains the neuroscience of consumer behavior. Learn exactly why people buy—and how to use that knowledge to improve pricing, increase sales, create better “brain-friendly” brand messaging, and be a more effective leader. Behavioral economics is the marketing research future of brands and business. This book goes beyond an academic understanding of behavioral economics and into practical applications. Learn how real businesses and business professionals can use science to make their companies better. Business owner, consultant, and behavioral economics expert Melina Palmer helps leaders like you use the psychology of the consumer, innovation, and truly impactful branding to achieve real, bottom-line benefits. Discover information and tools you can actually use to influence consumers. Go beyond data science and learn how the consumer brain works. Dramatically improve your effectiveness as a leader and marketer with: · Real-world examples that bring a concept to life and make it stick · Ideas to help you with problem solving for your business · Ways to hack your brain into coming up with innovative programs, products, and initiatives “A stand-out guide for anyone fascinated by customer behavior and the science of decision-making.” —Madeline Quinlan, cofounder of Salient Behavioral Consultants

“Captures the basic laws of growth companies and creates a new formula for success.” —Richard A. D’Aveni, Tuck School of Business, Dartmouth College Organic business growth is governed by its own natural laws—underlying truths that set the stage for growth and innovation, much in the way that Einstein’s theory of relativity accounts for the movement of objects in the space-time continuum. The most fundamental law is that uncertainty is the only certainty. Dominating forces are ambiguity and change; the processes at work involve exploration, invention, and experimentation. Unfortunately, these truths run counter to the principles of stability, predictability, and linearity that have long informed the design of our firms. The Physics of Business Growth explains how to create growth in today’s business environment, providing a roadmap and a set of practical tools to navigate its challenges. The book lays out a three-step formula that will prove invaluable to professionals who have the opportunity to influence growth now, as well as to tomorrow’s growth leaders, guiding them in (1) creating the right employee and organizational mindsets to enable growth, (2) building an internal corporate growth system, and (3) putting in place processes that result in identifying opportunities, launching growth experiments, and managing a growth portfolio. “Avoids the trap of magical thinking, which glosses over the messiness and complexity involved in growing a business. Rather, they offer a robust toolkit that growth leaders can adapt to their own circumstances.” —J. M. Ryan, Senior Fellow, Wharton Executive Education

This primer brilliantly exposes concepts related to special and general relativity for the absolute beginner. It can be used either as an introduction to the subject at a high school level or as a useful compass for undergraduates who want to move the first steps towards Einstein's theories. The book is enhanced throughout with many useful exercises and beautiful illustrations to aid understanding. The topics covered include: Lorentz transformations, length contraction and time dilation, the twin paradox (and other paradoxes), Minkowski spacetime, the Einstein equivalence principle, curvature of space and spacetime, geodesics, parallel transport, Einstein’s equations of general relativity, black holes, wormholes, cosmology, gravitational waves, time machines, and much more.

In 1921, five years after the appearance of his comprehensive paper on general relativity and twelve years before he left Europe permanently to join the Institute for Advanced Study, Albert Einstein visited Princeton University, where he delivered the Stafford Little Lectures for that year. These four lectures constituted an overview of his then-controversial theory of relativity. Princeton University Press made the lectures available under the title The Meaning of Relativity, the first book by Einstein to be produced by an American publisher. As subsequent editions were brought out by the Press, Einstein included new material amplifying the theory. A revised version of the appendix "Relativistic Theory of the Non-Symmetric Field," added to the posthumous edition of 1956, was Einstein's last scientific paper.

Puts the emphasis on conceptual questions: Why is there no such thing as absolute motion? What is the physical meaning of relativity of simultaneity? But, the most important question that is addressed in this book is "what is the nature of spacetime?" or, equivalently, "what is the dimensionality of the world at the macroscopic level?" Develops answers to these questions via a thorough analysis of relativistic effects and explicitly asking whether the objects involved in those effects are three-dimensional or four-dimensional. Discusses the implication of the result (this analysis clearly shows that if the world and the physical objects were three-dimensional, none of the kinematic relativistic effects and the experimental evidence supporting them would be possible) for physics, philosophy, and our entire world view are discussed.
