Written in the early days of the Soviet Unionand using examples from Mark Twain, H.G. Wells, Charles Darwin, and their Russian counterpartsthis lively bestseller from the 1930s is filled with answers to basic questions about physics.
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."
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.
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.
This is a book of entertaining problems that can be solved through the use of algebra, problems with intriguing plots to excite the readers curiosity, amusing excursions into the history of mathematics, unexpected uses that algebra is put to in everyday affairs, and more. Algebra Can Be Fun has brought hundreds of thousands of youngsters into the fold of mathematics and its wonders. It is written in the form of lively sketches that discuss the multifarious (and exciting!) applications of algebra to the world about us. Here we encounter equations, logarithms, roots, progressions, the ancient and famous Diophantine analysis and much more. The examples are pictorial, vivid, often witty and bring out the essence of the matter at hand. There are numerous excursions into history and the history of algebra too. No one who has read this book will ever regard mathematics again in a dull light" Reviewers regard it as one of the finest examples of popular science writing.
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.
This new version now contains answers to all the over 600 stimulating questions. Walker covers the entirety of naked-eye physics by exploring problems of the everyday world. He focuses on the flight of Frisbees, sounds of thunder, rainbows, sand dunes, soap bubbles, etc., and uses such familiar objects as rubber bands, eggs, tea pots, and Coke bottles. Many references to outside sources guide the way through the problems. Now the inclusion of answers provides immediate feedback, making this an extraordinary approach in applying all of physics to problems of the real world.· Hiding Under the Covers, Listening for the Monsters· The Walrus Speaks of Classical Mechanics· Heat Fantasies and Other Cheap Thrills of the Night· The Madness of Stirring Tea· She Comes in Colors Everywhere· The Electrician's Evil and the Ring's Magic· The Walrus Has His Last Say and Leaves Us Assorted Goodies
This book is different from other books of similar content, not in term of the material it contains but in term of the way this material is processed and presented. It does not only study the arithmetic topics studied in school, but also analyzes how these ones can be used in various other areas and in solving real life problems. Additionally, it does not try to turn enjoyable and entertaining problems into tedious tasks that are often fruitless for serious work. It avoids difficult problems and selects only the material that is accessible for the majority of the readers.
This volume presents students with problems and exercises designed to illuminate the properties of functions and graphs. The 1st part of the book employs simple functions to analyze the fundamental methods of constructing graphs. The 2nd half deals with more complicated and refined questions concerning linear functions, quadratic trinomials, linear fractional functions, power functions, and rational functions. 1969 edition.
