Bøger af Yakov Perelman

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. Among them was Grigori Yakovlevich Perelman, the Russian mathematician (unrelated to the author), who solved the Poincaré conjecture, and who was awarded and rejected the Fields Medal. Grigori's father, an electrical engineer, gave him Physics for Entertainment to encourage his son's interest in mathematics. 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." Ideas from this book are still used by science teachers today. Yakov Isidorovich Perelman died in the siege of Leningrad in 1942.

This is another book is Yakov Perelman's successful series of science books. Presented in an easy form, well within the reach of most astronomy amateurs, it is useful introduction to this science. Through five key chapters (the Earth, the Moon, planets, stars, and gravitation), the author analyses the most important aspects of modern astronomy.

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 concepts that so often make the reader shy of books on astronomy. The book contains chapters relating to the Earth, the Moon and other planets. The author has concentrated on materials not usually discussed in works of this nature. This book is written in a witty style and remains a reference for astronomy students around the world.

Physics for Entertainment. By Yakov Perelman. & The Inventions Researches and Writings of Nikola Tesla With Special Reference To His Work In Polyphase Currents And High Potential Lighting. By Thomas Commerford Martin

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 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.

First published in 1915, a best-seller in the 1920s and long out of print, Interplanetary Travel is a short excursion into space physics. Using conundrums, entertaining examples, and unexpected comparisons, Yakov Perelman dispelled some of the public prejudice that prevailed against celestial mechanics and physics of being too abstract and unable to nourish the mind. He explored, in a witty style, the opportunity of successfully completing the flights imagined in some novelists' wildest fantasies. He checked and corrected their boldest ideas. Even today, this book remains a reference for science students around the world.

This title consists of the following two complete books by By Thomas Commerford Martin, and Yakov Perelman: The Inventions Researches and Writings of Nikola Tesla with Special Reference to His Work in Polyphase Currents and High Potential Lighting. By Thomas Commerford Martin & Physics for Entertainment. By Yakov Perelman.

This short book is a collection of simple and easily grasped tricks to speed up your mental arithmetic. If you want to master them you should realize that to be used fully they need to be approached conscientiously, not mechanically. But it pays to master them as they will enable you to do calculations in your head without error, as with written calculations.

Ce petit livre est une collection d'astuces et de techniques qui permettent d'accélérer votre calcul mental. Si vous voulez les maîtriser et les utiliser pleinement, vous devez les aborder consciencieusement et non mécaniquement. Ils vous permettront de faire les calculs mentalement, sans erreur, comme si ces derniers étaient des calculs écrits.

In this book, we look into some entertaining stories from famous authors (Leo Tolstoy, Jules Verne, Jonathan Swift, etc.) and analyze them from a scientific point of view. Using simple mathematics and physics tools, we will be able to derive new entertaining questions and answers from these stories. In some occasions, we will be able to accept or refuse the foundations underlying them.

“Mechanics for fun” is not a textbook. Instead it is a complementary book with some entertaining experiments and descriptions of some exciting natural phenomena. Its aim is to excite the reader interest in mechanics and have him engage in its study. The author has included a number of mechanics’ applications in engineering, sports, circus performances and many other unexpected areas.

This book is not a usual arithmetic book. It does not present arithmetic concepts as tedious problems that are often fruitless for everyday life. Instead, using material that is accessible to the majority of the readers, it presents multiple tricks, puzzles and problems, and explains the notions behind them in an enjoyable and entertaining manner. It is recommended for both young students (as a complement to textbooks) and adults.

"... I note that this book can be seen as an extensive physics quiz which should help the reader assessing whether he actually masters the basics of physics. However, this is not a quiz that you would find in a traditional physics exam. While seemingly simple, the questions often surprise the reader and the quick intuitive answers to these one are often wrong. The ultimate purpose of the book is to convince the reader that the domain of physics is much richer in content than many people think, and incidentally to pay attention to the misconception of a number of physical representations. This book will encourage readers to critically review and carefully check their physics knowledge..."

" Are we ever destined to travel to other planets? Or are we forever doomed to remain prisoners of Earth? The idea of interstellar travel, flying from one planet to another, is, of course, for the time being, no more than a tempting dream. We have been talking and dreaming about Leonardo da Vinci aircraft for many centuries before it became a reality. Why not admit that, over time, the dream of space travel will one day become a reality. Spaceships will rush into the universe and will move the former captives of the Earth to the Moon, the planets and even perhaps planets in other star systems... And who knows, among the current timid attempts to mentally solve this daunting problem some will be translated into reality? ..."

"Physics at Every Step" does not seek to replace physics 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. It includes hundreds of colorful stories from the field of physics. Despite their entertaining appearance, these ones address several important and serious notions in this field.

This motley collection features more than 100 puzzles involving coin tricks, chess problems, magic squares, and a host of other intriguing scenarios. Minimal mathematical knowledge required. Includes solutions.
