Unfortunately, the extent of our physics knowledge still does not allow us to see clearly the crucial importance of this science. A wide range of physics notions such as the theory of motion, strength, force, and mechanics in general are still vague for beginners. Those "who do not know movement, do not understand nature" Aristotle once said. Although several pages of the author's book "Physics for Entertainment" (2 volumes) are dedicated to mechanics' problems, it very useful that he devoted a separate, but similarly written, book to mechanics. "Mechanics for Entertainment" is not a textbook. Instead it is a freestyle book with some entertaining experiments and descriptions of some exciting natural phenomena. I have included a number of mechanics laws applications in engineering, sports, circus performances and many other unexpected areas.

Published in 1913, a best-seller in the 1930s and long out of print, Physics for Entertainment was translated from Russian into many languages and influenced science students around the world. In the foreword, the book's author describes the contents as "conundrums, brain-teasers, entertaining anecdotes, and unexpected comparisons," adding, "I have quoted extensively from Jules Verne, H. G. Wells, Mark Twain and other writers, because, besides providing entertainment, the fantastic experiments these writers describe may well serve as instructive illustrations at physics classes." The book's topics included how to jump from a moving car, and why, "according to the law of buoyancy, we would never drown in the Dead Sea."

This book contains hundreds of colorful stories from the field of physics. Despite their entertaining appearance, they address several important and serious notions in this field. This book does not seek to replace school textbooks. Its purpose is to entice the reader to consciously observe physical phenomena, including the simplest ones which we have learned to ignore in our everyday life. It allows the reader to amass evidence about physical laws, and engage in a systematic study of physics.

Automated Lighting: The Art and Science of Moving Light in Theatre, Live Performance and Entertainment continues to be the most trusted text for working and aspiring lighting professionals. Now in its second edition, it has been fully updated to include new advances in lamp sources such as LEDs and plasma lamps, automated and programmable displays, updates for managing color, and new methods for using electronics. Its clear, easy-to-understand language also includes enough detailed information for the most experienced technician and engineer.

Astronomy is a fortunate science; it needs no embellishments, said the French savant Arago. So fascinating are its achievements that no special effort is needed to attract attention. Nonetheless, the science of the heavens is not only a collection of astonishing revelations and daring theories. Ordinary facts, things that happen, day by day, are its substance. Most laymen have, generally speaking, a rather hazy notion of this prosaic aspect of astronomy. They find it of little interest, for it is indeed hard to concentrate on what is always before the eye.Everyday happenings in the sky are the contents of this book, free from professional terminology with easy reading. Its purpose is to initiate the reader into the basic facts of astronomy. Ordinary facts with which you may be acquainted are couched here in unexpected paradoxes, or slanted from an odd and unexpected angle solely to excite the imagination and quicken your interest. The daily aspect of the science of the skies, its beginnings, not later findings that mainly form the contents of Astronomy for Entertainment. The purpose of the book is to initiate the reader into the basic facts of astronomy. Ordinary facts with which you may be acquainted are couched here in unexpected paradoxes, or slanted from an odd and unexpected angle. The theme is, as far as possible, free from "terminology" and technical paraphernalia that so often make the reader shy of books on astronomy.Books on popular science are often rebuked for not being sufficiently serious. In a way the rebuke is just, and support for it can be found (if one has in mind the exact natural sciences) in the tendency to avoid calculations in any shape or form. And yet the reader can really master his subject only by learning how to reckon, even though in a rudimentary fashion. True, he has taken care to present them in an easy form, well within the reach of all who have studied mathematics at school. It is his conviction that these exercises help not only retain the knowledge acquired; they are also a useful introduction to more serious reading.This book contains chapters relating to the Earth, the Moon, planets, stars and gravitation. The author has concentrated in the main on materials not usually discussed in works of this nature. Subjects omitted in the present book, will, he hopes, be treated in a second volume. The book, it should be said, makes no attempt to analyze in detail the rich content of modern astronomy.Unfortunately Y. Perelman never wrote the continuation he had planned for this book, as untimely death in war bound Leningrad in 1942 interrupted his labours.

Discusses the essential elements in creating a successful game, how playing games and learning are connected, and what makes a game boring or fun.

Most of us are unaware of how much we depend on quantum mechanics on a day-to-day basis. Using illustrations and examples from science fiction pulp magazines and comic books, The Amazing Story of Quantum Mechanics explains the fundamental principles of quantum mechanics that underlie the world we live in.

#1 NEW YORK TIMES BESTSELLER • A “bracing” (Vox) guide for surviving and resisting America’s turn towards authoritarianism, from “a rising public intellectual unafraid to make bold connections between past and present” (The New York Times) “Timothy Snyder reasons with unparalleled clarity, throwing the past and future into sharp relief. He has written the rare kind of book that can be read in one sitting but will keep you coming back to help regain your bearings.”—Masha Gessen The Founding Fathers tried to protect us from the threat they knew, the tyranny that overcame ancient democracy. Today, our political order faces new threats, not unlike the totalitarianism of the twentieth century. We are no wiser than the Europeans who saw democracy yield to fascism, Nazism, or communism. Our one advantage is that we might learn from their experience. On Tyranny is a call to arms and a guide to resistance, with invaluable ideas for how we can preserve our freedoms in the uncertain years to come.
