?In this book, my aim is to provide the reader with a foundation in general topology that will adequately prepare him for further work in a broad variety of mathematical disciplines. The arrangement of the material is such that the book can also serve as a reference for the more advanced mathematician.
The reader is assumed to have a background of at least one semester of rigorous analysis; for such persons, the treatment herein is self- contained and the material can easily be covered in a two-semester course.
Chapters I-II provide a short introduction to the axiomatic foundations of set theory. Chapters III-VI are devoted to general topological structures; the emphasis is on the mapping, and an extended treatment of identifications is given. Separation axioms are introduced in Chapter VII; after that, with only very few and explicitly noted exceptions, all spaces in the book are assumed to be Hausdorff. By imposing increasingly more severe conditions on the topology, the development proceeds down the hierarchy of topological spaces to the metric spaces; then convergence, compactness, function spaces, and completeness are taken up. The use of homotopy methods in general topology is started in Chapter XV. In the usual manner, these methods lead to "elementary" proofs of the classical results in Euclidean n-space, such as Brouwer's fixed-point and domain-invariance theorems; a proof of the complete Jordan curve theorem is also given. After discussing the homotopy
classification of spaces and some of its features, the entry of algebra into topology (via the fundamental and higher homotopy groups) is presented in Chapter XIX ; this chapter is part of some work that was done jointly with W. Hurewicz.
The last chapter is devoted to the covering homotopy theorem in fiber spaces and illustrates an interplay between many of the
concepts discussed in the book. Two appendices, one on linear topological spaces and the other on limit spaces, are included.
Nearly every definition is followed by examples illustrating the use of the abstract concept in some fairly concrete situations. This device makes the book suitable for self-study. It also enables the instructor who uses the book as a text to proceed rapidly to those parts of the subject that he deems of greater importance.
Remarks, in small type, call attention either to further developments, or to direct applications in other branches of mathematics.
The problems, which are given at the end of each chapter, can all be solved by the methods developed in the book. Moreover, no proof in the text relies on the solution of any problem. Some of the problems are routine. Others are important theorems that complement the material in the text; these are accompanied by hints for their solution.
The notation of symbolic logic used throughout the book is given immediately after the table of contents.

Philosophy of Biology is a rapidly expanding field. It is concerned with explanatory concepts in evolution, genetics, and ecology. This collection of 25 essays by leading researchers provides an overview of the state of the field. These essays are wholly new; none of them could have been written even ten years ago. They demonstrate how philosophical analysis has been able to contribute to sometimes contested areas of scientific theory making.

-Written by internationally acknowledged leaders in the field
- Entries make original contributions as well as summarizing state of the art discoveries in the field
- Easy to read and understand

The popularity of dinosaurs seems never ending, fuelled by films such as Jurassic Park and documentaries (Walking with Dinosaurs). But how much do these popular programmes really tell us about the recent scientific discoveries and the latest research into the world of the dinosaur? This is the first book to tell the general reader about what's really happening now in dinosaur research. It tells the story behind the exciting scientific discoveries that have built up a picture of how dinosaurs looked, what they ate, how they moved and interacted with each other. This new approach to this subject involves the combination of many areas of science (eg. anatomy, cosmology, physics, mechanics and engineering design) to piece together the evidence of how animal/plant life evolved on earth, and why it did in the way that it did. David Norman also talks about the part that informed speculation and luck play in major discoveries. Starting with ancient myths of dinosaur-like monsters (dragons) and the history of the discovery of dinosaurs, he goes on to discuss the evolution of Dinosaurs and the many different techniques used to understand them, including the latest virtual reality animation sequences and engineering design analysis.

"A Gem of a book for Seekers of the Path. There aren't too many books I can name that have changed my life - but (Revelations of the Unseen) Futuh Al-Ghaib is one of them."
"Few people realise that this Saint was hugely influential in the Asian subcontinent and many of us from the region had not heard of Ibn Arabi - who seems to have been highly influential in the West... This book changed my life and other people's too. I gave to a friend as a gift and the next year he wrote to me saying this book had influenced him to go the Hajj... Abd Al Qadir Jilani's way is a journey of discovering the origins of self and this book is a good introduction into the world of this saintly sage."

The periodic table is one of the most potent icons in science. It lies at the core of chemistry and embodies the most fundamental principles of the field. The one definitive text on the development of the periodic table by van Spronsen (1969), has been out of print for a considerable time. The present book provides a successor to van Spronsen, but goes further in giving an evaluation of the extent to which modern physics has, or has not, explained the periodic system. The book is written in a lively style to appeal to experts and interested lay-persons alike. The Periodic Table begins with an overview of the importance of the periodic table and of the elements and it examines the manner in which the term 'element' has been interpreted by chemists and philosophers. The book then turns to a systematic account of the early developments that led to the classification of the elements including the work of Lavoisier, Boyle and Dalton and Cannizzaro. The precursors to the periodic system, like Dobereiner and Gmelin, are discussed. In chapter 3 the discovery of the periodic system by six independent scientists is examined in detail. Two chapters are devoted to the discoveries of Mendeleev, the leading discoverer, including his predictions of new elements and his accommodation of already existing elements. Chapters 6 and 7 consider the impact of physics including the discoveries of radioactivity and isotopy and successive theories of the electron including Bohr's quantum theoretical approach. Chapter 8 discusses the response to the new physical theories by chemists such as Lewis and Bury who were able to draw on detailed chemical knowledge to correct some of the early electronic configurations published by Bohr and others. Chapter 9 provides a critical analysis of the extent to which modern quantum mechanics is, or is not, able to explain the periodic system from first principles. Finally, chapter 10 considers the way that the elements evolved following the Big Bang and in the interior of stars. The book closes with an examination of further chemical aspects including lesser known trends within the periodic system such as the knight's move relationship and secondary periodicity, as well at attempts to explain such trends.

Since the enormously successful first edition of Forensic DNA Typing was published, the Human Genome Project has published a draft sequence of the human genome and completed the finished reference sequence. The advent of modern DNA technology has resulted in the increased ability to perform human identity testingdesirable in a number of situations including the determination of perpetrators of violent crime such as murder and rape, resolving unestablished paternity, and identifying remains of missing persons or victims of mass disasters. The technology has been utilized in identifying remains from victims of the World Trade Center twin towers collapse following the terrorist attacks of September 11, 2001, the President Clinton-Monica Lewinsky scandal, and the identification of the remains in the Tomb of the Unknown Soldier. Indeed, our perceptions of history have been changed with DNA evidence that revealed Thomas Jefferson fathered a child by one of his slaves. This book examines the science of current forensic DNA typing methods by focusing on the biology, technology, and genetic interpretation of short tandem repeat (STR) markers, which encompass the most common forensic DNA analysis methods used today. Ten new chapters have been added to accommodate the explosion of new information since the turn of the century.

Medical practitioners and the ordinary citizen are becoming more aware that we need to understand cultural variation in medical belief and practice. The more we know how health and disease are managed in different cultures, the more we can recognize what is "culture bound" in our own medical belief and practice.

The Encyclopedia of Medical Anthropology is unique because it is the first reference work to describe the cultural practices relevant to health in the world's cultures and to provide an overview of important topics in medical anthropology. No other single reference work comes close to marching the depth and breadth of information on the varying cultural background of health and illness around the world. More than 100 experts - anthropologists and other social scientists - have contributed their firsthand experience of medical cultures from around the world.
