Whether you are a teacher, student, or just someone who enjoys science, dipping into this collection is much like opening a holiday gift and discovering a marvelous little toy that then holds your attention by some curious performance. Here are, in effect, nearly two hundred such toys.  \nThis book precisely reflects the way science education should be, especially at the introductory level. The primary reason scientists become scientist’s is that science is a thoughtful form of play. It is fun to see an arrangement of common items behave in a surprising way and to try to fig-ure out why it acts that way. We learn science because it reveals the otherwise hidden simplicity of how the world works, and often that revelation is so surprising that we might even laugh.  \nThat is the way science should be taught, but too often it is demonstrated with large, noisy, foreboding apparatus, things that students or other onlookers find alien and removed from everyday life. Sometimes the element of strangeness is so strong that even a simple principle may be obscured by it. Such apparatus may be impressive but may not be educational, because they and the principles they demonstrate may be quickly forgotten. The demonstrations that are long remembered (and retold to others) are the simple ones that are fashioned from everyday objects.  \nEhrlich has gathered together here simple demonstrations, each tested and tagged with a concise and accessible explanation. If you are a teacher, you will find them especially valuable because they have been chosen for a minimum of expense and setup time. If you are not a teacher, you will find them just as valuable because they open up the world of science without needing costly or intimidating equipment.  \nOnce read, this book serves another purpose—you will begin to think like Ehrlich and discover other, similarly simple demonstrations that can be made from common objects.  \nIntroduction  \nAnyone curious about the physical universe cannot help but be intrigued by simple demonstrations of physical principles at work. Albert Einstein wrote that as a small boy he first became aware of a hidden order in the universe by witnessing the behavior of a compass. We may speculate that his lifelong search for order, even though couched in esoteric mathematics, had its roots in simple observations and in simple “thought experiments.” Even those of us lacking Einstein’s deep insight and mathematical abilities can still find our understanding of the physical universe deepened, or our curiosity aroused, by witnessing a range of simple demonstrations.  \nThis book is a collection of physics demonstrations for teachers, students, and laypersons who have a curiosity about the physical world. Many are suitable for use in a variety of educational settings, ranging from middleschool physical science classes to university level physics courses, but because of their simplicity most can be performed by students outside of class—indeed, by anyone.  \nAs a university physics teacher I have noticed that most of my colleagues love to watch a good demonstration, but rarely do demonstrations in their own classes. The problem seems to be that, except for those fortunate enough to teach at a university with a staffed demonstration facility, setting up demonstrations for classes is too much effort. There is an enormous amount of work involved in designing, constructing, physically locating, and setting up a demonstration that works reliably. Accordingly, I have written this book with the intention of compiling a list of demonstrations whose simplicity and convenience will, I hope, stimulate increased use of demonstrations, both in and out of class, and perhaps even turn the attention of some future Einstein toward the myster","cbCaimFIcGZS4w35","https://ap.wps.com/l/cbCaimFIcGZS4w35","pdf",1846524,227,"English","# Foreword\n# Introduction\n## Purpose and audience\n## Transparency and educational criteria\n## Low cost and simplicity of design\n## Feasibility and safety\n## Compactness","[{\"question\":\"Who is Turning the World Inside Out written for?\",\"answer\":\"It is aimed at teachers, students, and laypersons who are curious about the physical world and want simple demonstrations they can perform easily.\"},{\"question\":\"What does the book mean by “transparency” in its demonstrations?\",\"answer\":\"Transparency has two meanings: the experiments explain underlying physics in a simple way and many can be done with an overhead projector for classroom use.\"},{\"question\":\"How does the book ensure demonstrations are practical and safe?\",\"answer\":\"Demonstrations are selected for low cost, simple design, feasibility, and reliability, while avoiding unsafe materials and high voltages and including safety tips when needed.\"}]","Turning the World Inside Out - (And 174 other simple Physics Demonstrations) | PDF",1792209610,572]
