Mathematical Recreations and Essays W. W. Rouse Ball For nearly a century, this sparkling classic has provided stimulating hours of entertainment to the mathematically inclined. The problems posed here often involve fundamental mathematical methods and notions, but their chief appeal is their capacity to tease and delight. In these pages you will find scores of "recreations" to amuse you and to challenge your problem-solving faculties-often to the limit. Now in its 13th edition, Mathematical Recreations and Essays has been thoroughly revised and updated over the decades since its first publication in 1892. This latest edition retains all the remarkable character of the original, but the terminology and treatment of some problems have been updated and new material has been added. Among the challenges in store for you: Arithmetical and geometrical recreations; Polyhedra; Chess-board recreations; Magic squares; Map-coloring problems; Unicursal problems; Cryptography and cryptanalysis; Calculating prodigies; ... and more. You'll even find problems which mathematical ingenuity can solve but the computer cannot. No knowledge of calculus or analytic geometry is necessary to enjoy these games and puzzles. With basic mathematical skills and the desire to meet a challenge you can put yourself to the test and win. "A must to add to your mathematics library."-The Mathematics Teacher We are delighted to publish this classic book as part of our extensive Classic Library collection. Many of the books in our collection have been out of print for decades, and therefore have not been accessible to the general public. The aim of our publishing program is to facilitate rapid access to this vast reservoir of literature, and our view is that this is a significant literary work, which deserves to be brought back into print after many decades. The contents of the vast majority of titles in the Classic Library have been scanned from the original works. To ensure a high quality product, each title has been meticulously hand curated by our staff. Our philosophy has been guided by a desire to provide the reader with a book that is as close as possible to ownership of the original work. We hope that you will enjoy this wonderful classic work, and that for you it becomes an enriching experience.
John Wallis (1616-1703) was the most influential English mathematician prior to Newton. He published his most famous work, Arithmetica Infinitorum, in Latin in 1656. This book studied the quadrature of curves and systematised the analysis of Descartes and Cavelieri. Upon publication, this text immediately became the standard book on the subject and was frequently referred to by subsequent writers. This will be the first English translation of this text ever to be published.
A Discourse Concerning Algebra, provides a new and readable account of the rise of algebra in England from the Medieval period to the later years of the 17th Century.Stedall's book follows the reception and dissemination of important algebraic ideas and methods from continental Europe and the consequent revolution in the state of English mathematics in the 17th century.
NB THIS IS THE BLACK & WHITE VERSION.The Numerical Universe sets out to show that there exists a primordial, numerical, geometric and musical structure to the Universe. The proposal is simply that there is only order in the universe; that there is no chaos and that we are not all here by virtue of some incredible stroke of luck. The universe is instead shown to be the effect produced by a perfectly balanced, always in equilibrium, numerical order, inherent to the decimal system of numbers 0 to 9.The book starts with a look at the numerical structure and how the decimal system of numbers work in specific pairs and groups, making use of modular arithmetic - the reader won't need any formal mathematical training to follow the arguments and analysis. In the second section there is analysis of the group of 20 amino acids which are common to all life and which reveal the canonical, numerical, geometric and ultimately musical biological template that pervades the created Universe.The final section of the book demonstrates how the Integer Partition Table of Numbers might well be the numerical algorithm used to create and structure the whole of the universe. Numbers are seen to organise themselves in such a way that they unfold as an elegant geometric integration to produce a holographic universe.Hard evidence of this ancient knowledge may be found in analysis of the Great Pyramid, Stonehenge, famous cathedrals like Wells and Chartres, and all the megalithic sites, that are shouting this numerical canon that it may never be lost. The theory offers extraordinary new insights into the central question of natural philosophy, the origin of the Fine Structure Constant, the force that essentially holds us and the universe together and that stops us from flying apart, and the famous number 137, that has so obsessed some of the greatest thinkers of the 20th Century.Enduring mysteries concerning Prime Numbers, Photosynthesis, Plato, Dante's 55 Stelle, the 153 Fish in the Bible, and the SATOR Square recovered from the ruins of Pompeii - all can be readily explained and understood by application of this number theory which can potentially project our learning and advancement like no theory yet conceived. This effort has pieced together the work of many great men and women and it is by standing upon their shoulders that this theory of everything can come to you at all. Otherwise, I have simply let intuition be my guide and have been rewarded by a flow of incredible synchronicity that has allowed me to progress the theory to this stage. Without claiming to have all the answers by any means the hope is that this work will provide the inspiration for the research of many others. It feels like I have opened a crack in a door that has been shut for a very long time.

'Not tonight, darling, I've got a headache...' An estimated one in three couples suffer from problems associated with one partner having a higher libido than the other. Marriage therapist Michele Weiner Davis has written THE SEX-STARVED MARRIAGE to help couples come to terms with this problem. Weiner Davis shows you how to address pyschological factors like depression, poor body image and communication problems that affect sexual desire. With separate chapters for the spouse that's ready for action and the spouse that's ready for sleep, THE SEX-STARVED MARRIAGE will help you re-spark your passion and stop you fighting about sex. Weiner Davis is renowned for her straight-talking style and here she puts it to great use to let you know you're not alone in having marital sex problems. Bitterness or complacency about ho-hum sex can ruin a marriage, breaking the emotional tie of good sex.
