Product Description
This book contains the definitive, illustrated history of one of the most popular and important mechanical puzzles of all time. It can be argued that the Fifteen Puzzle in 1880 had the greatest impact on American and European society during of any mechanical puzzle the world has ever known.
Books by famous mathematicians tell that a deaf mute invented the 15 puzzle, but encyclopedias, other books and web sites say it was invented by Sam Loyd who Martin Gardner called "America's greatest puzzle designer". Or has Sam Loyd, who said he invented the puzzle, continued to fool the world for more than 100 years?

Advanced IQ Tests

Advanced IQ Tests

Introduction
In several of my earlier Kogan Page titles I have provided readers with the opportunity to obtain a greater understanding of IQ testing by means of practice tests in which readers have been able to familiarize themselves with the type of questions they are likely to encounter when taking such tests. In this book I have retained some of the question types that have appeared in my previous books but have also introduced several new types of questions designed to measure an advanced level of numerical, verbal and spatial ability, as well as questions involving the use of logical analysis, lateral thinking and problem-solving abilities. The object of this book, therefore, is to present readers with an even greater challenge in which the 12 separate tests have a higher than usual overall degree of difficulty. Such tests are particularly useful to anyone who may need to undertake graduate and managerial selection in the future. They are also of value to any professional who contemplates seeking other positions
which may involve the use of psychometric testing as part of the selection process, or as a means of internal advancement in the organization in which they are employed. The book will also appeal to people wishing to test themselves on more challenging questions by moving on from the standard-level IQ tests of previous books. These readers, who have already familiarized themselves with the type of IQ tests contained in my previous books, will now be ready to move on to a greater challenge. As with athletes who push out the boundary of their abilities by the use of even more rigorous training schedules and refinement of techniques, an increase in brainpower can be achieved by taking on greater mental tasks and challenges. A further advantage to be gained from tackling the more advanced questions is that readers will automatically improve their performance on standard IQ test questions. Because they have been newly compiled for this book, the tests that follow have not been standardized, so an actual IQ rating cannot be given. However, there is a guide to performance at the end of each test, and there is also a cumulative guide for your overall performance on all 12 tests. The performance assessment is particularly useful to users of this book as the feedback provided will give them the opportunity to identify their own strengths and weaknesses. This will enable readers to build on their strengths and work at improving their performance in areas of weakness. Each test consists of 30 questions. The tests are all multidisciplinary, which provides the opportunity to practise on the range of questions you are likely to encounter in actual IQ tests. A time limit of 120 minutes is allowed for each test. Answers and explanations, where necessary, are provided and you should award yourself one point for each completely correct answer. The use of a calculator is not permitted in respect of the numerical questions, which are designed to test your aptitude when working with numbers as well as your powers of mental arithmetic.

How To Control Your Brain At Will

 How To Control Your Brain At Will

Description:
Over the last few years, a number of works of this kind have appeared, and my adding a stone to the edifice was above all a response to the needs of my patients; I also wished to enlighten people as to the cause of these nervous disorders, known under various names such as neurasthenia, psychoneurosis or psychasthenia; and finally to develop my personal point of view on the subject of treatment. So it is above all the patients, suffering from these disorders, whom I am addressing, and that is why I tried, as much as possible, to simplify anything in this study which seemed too abstract. My primary objective is to show you, as best I can, why people get sick, and how they can be cured. This training method, if I may be permitted to call it that, is based on the certainty that all psychasthenic disorders are caused by a malfunction in the brain, and that it is in the brain, and nowhere else, that we must look for solutions.

Here's an example of just one brain-baffling challenge:
Starting at midnight, snow fell 1 1/2" every 6 hours. If there was already 2 1/4" of snow at midnight, what was the thickness of the snow at 9 o'clock?
So start using that gray matter to its fullest and watch in amazement as your IQ soars to exceptional heights.
