CALCULUS For the Practical Man by J. E. THOMPSON. Originally published in 1931. PREFACE: THIS book on simplified calculus is one of a series designed by the author and publisher for the reader with an interest in the meaning and simpler technique of mathematical science, and for those who wish to obtain a practical mastery of some of the more usual and directly useful branches of the science without the aid of a teacher. Like the other books in the series it is the outgrowth of the author's experience with students such as those mentioned and the demand experienced by the publisher for books which may be read as well as studied. One of the outstanding features of the book is the use of the method of rates instead of the method of limits. To the conven tional teacher of mathematics, whose students work for a college degree and look toward the modern theory of functions, the author hastens to say that for their purposes the limit method is the only method which can profitably be used. To the readers contem plated in the preparation of this book, however, the notion of a limit and any method of calculation based upon it always seem artificial and not hi any way connected with the familiar ideas of numbers, algebraic symbolism or natural phenomena. On the other hand, the method of rates seems a direct application of the principle which such a reader has often heard mentioned as the extension of arithmetic and algebra with which he must become acquainted before he can perform calculations which involve changing quantities. The familiarity of examples of changing quantities in every-day life also makes it a simple matter to in troduce the terminology of the calculus; teachers and readers willrecall the difficulty encountered in this connection in more formal treatments. The scope and range of the book are evident from the table of contents. The topics usually found in books on the calculus but not appearing here are omitted in conformity with the plan of the book as stated in the first paragraph above. An attempt has been made to approach the several parts of the subject as naturally and directly as possible, to show as clearly as possible the unity and continuity of the subject as a whole, to show what the calculus is all about and how it is used, and to present the material in as simple, straightforward and informal a style as it will permit. It is hoped thus that the book will be of the greatest interest and usefulness to the readers mentioned above. The first edition of this book was prepared before the other volumes of the series were written and the arrangement of the material in this volume was not the same as in the others. In this revised edition the arrangement has been changed somewhat so that it is now the same in all the volumes of the series.

Many of the earliest books, particularly those dating back to the 1900s and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original text and artwork.

Darkness and Light: My Story is the heart-wrenching and soul-stirring autobiography of footballer and two-time cancer survivor, Joe Thompson. His mother's battle with mental illness and father's descent into a life of drugs and crime saw him battle adversity from birth. Football opened up a new world of opportunity when Manchester United signed him, aged nine. Joe spent six years living every boy's dream but was left devastated when the club released him at 16. He bounced back to forge a career in the Football League, before his life was thrown into turmoil. At 23, he was diagnosed with a rare form of blood cancer. Six months of chemotherapy followed, which eventually rid his body of the disease. He had been given a second chance at life, but three years later he was given the shock news that his cancer had returned. An 18-day stay in an isolation unit reduced him to skin and bone, but he vowed that he wouldn't be beaten. For a second time, Joe gave cancer the boot and he has since made an incredible return to professional football.
