Unlike many textbooks or popular science books, A Simple Guide to Popular Physics has truly been crafted for the uninitiated or those spooked by the subject's complexity. Harris's inviting guide promises to give "absolute beginners" from "teens to centenarians" a basic grounding in particle physics, quantum physics, and cosmology-all without making readers do math. With the goal of introducing the basics and encouraging readers to explore more deeply afterwards, Harris notes "Like the fish we have no notion of what is beyond the boundaries of our knowledge, but unlike the fish, we know there is something." He starts by presenting those boundaries, the fundamentals of classic physics (Newton's law, states of matter, types of energy), with crisp clarity before laying out an accessible explanation of Einstein's theory of relativity, the structure of the atom, the mysteries of quantum mechanics and cosmology. Readers will not need to search online for key terms or explanations of concepts that have been glossed over. Instead, one by one, with patience and good humor, Harris introduces each of these building blocks of our universe, taking a little time to invite readers to contemplate the momentousness of the information, as in the chapter titled nothing less than "What Is Reality?" The watchword, here, is clarity, which Harris offers throughout, with professional illustrations and illuminating accounts of experiments and breakthroughs, offering a solid foundation for understanding and future reading.

If you move at high speed, time slows down, space squashes up and you get heavier. Travel fast enough and you could weigh as much as a jumbo jet, be flattened thinner than a CD without feeling a thing-and live forever As for the angles of a triangle, they do not always have to add up to 180 degrees. And then, of course, there are black holes. These are but a few of the extraordinary consequences of Einstein's theory of relativity. It is now over a hundred years since he made these discoveries, and yet the general public is still largely unaware of them. Filled with illuminating anecdotes and fascinating accounts of experiments, this book aims to introduce the interested lay person to the subject of relativity in a way which is accessible and engaging and at the same time scientifically rigorous. With relatively few mathematical equations--nothing more complicated than the Pythagoras's Theorem--this VSI packs a lot time into very little space, and for anyone who has felt intimidated by Einstein's groundbreaking theory, it offers the perfect place to start.

Wie entsteht die Lorentz-Kraft? Was haben Felder mit Teilchen zu tun? Wieso ist Eichinvarianz anders? Leonard Susskind und Art Friedman erklaren nicht alles, was es uber Spezielle Relativitatstheorie und Elektrodynamik zu wissen gibt - sondern alles Wichtige. Mit diesem Buch bekommen begeisterte Physik-Amateure die notwendige Mathematik und Formeln an die Hand, die sie fur ein wirkliches Verstandnis benoetigen. Die Autoren erklaren mit witzigen und hilfreichen Dialogen, grundlegenden UEbungen und glasklaren Erlauterungen die Spezielle Relativitatstheorie und Elektrodynamik so einfach wie moeglich, aber nicht einfacher.
