Gemmology
Since Gemmology was published, readers have used it to gain an in-depth appreciation of the science of gemmology, its history, and practice. This third edition has been completely revised to cover the latest methods of gem enhancement and identification, as well as the latest test instruments and laboratory techniques. Gemmology serves as an invaluable reference guide for gemmologists, professionals, and students, and is an invaluable text for anyone in the gemmological profession. Also included are details of the Gemmological Association s Foundation Course together with advice on examination techniques. "
Beginner's Guide to Gemmology
Beginner's Guide to Gemmology presents the profiles of the principal gem materials. This book discusses the interesting characteristics of gemstones as the growing consumer market jewelry resulted in increased sales of gem testing instruments. Organized into 12 chapters, this book begins with an overview of the development of the science of gemmology. This text then explains the fundamental qualities necessary in a gem, including color, hardness, specific gravity, crystallography, refractive index, pleochroism, critical angle, luminescence, and absorption spectra. Other chapters consider the organic gem materials, including amber, ivory, coral, tortoiseshell, jet, ebony, and pearl. This book discusses as well the various methods used in the production of man-made gemstones and the commercial use in gem testing. The final chapter deals with the composition of synthetic gemstones. This book is a valuable resource for gemmologists and jewelers. Students who intend to become a qualified gemologist will also find this book extremely useful.
Gemmology
Gemmology is a text for students preparing for the Gemmological Association's Preliminary and Diploma examinations. The book is more expansive and up-to-date than the author's earlier book, Beginner's Guide to Gemmology. The book deals with the practical and theoretical sides of gemmology. Tracing the background and science of gemmology, the book covers the gem material, geological formation, and occurrence of gemstones on the earth. The composition of gemstones from the atoms, elements, molecules, and compounds comprising them is analyzed, and the relationship between chemical composition and durability of the stone is explained. The basics of crystallography is mentioned as a tool toward u...
Gemmological Instruments
Gemmological Instruments deals with the developments in diamond grading equipment and gem testing instruments since the publication of the first edition in 1978. These developments include improvements in the versatility and styling of existing instruments such as the reflectivity meter, the composite spectroscope, and the refractometer. It also addresses the criticisms in the first edition and provides a discussion of the advantages and disadvantages of different gem testing equipment. This book is organized into 16 chapters that describe groundbreaking instruments like the thermal conductiv.
Design Thinking
In Design Thinking Peter Rowe provides a systematic account of the process of designing in architecture and urban planning. He examines multiple and often dissimilar theoretical positions whether they prescribe forms or simply provide procedures for solving problems—as particular manifestations of an underlying structure of inquiry common to all designing. Over 100 illustrations and a number of detailed observations of designers in action support Rowe's thesis.
How to Read a Graveyard
Looks at graveyards and burial practices and the ways that they can help us understand how people have understood and dealt with death.
Computer-Related Risks
"This sobering description of many computer-related failures throughout our world deflates the hype and hubris of the industry. Peter Neumann analyzes the failure modes, recommends sequences for prevention and ends his unique book with some broadening reflections on the future." —Ralph Nader, Consumer Advocate This book is much more than a collection of computer mishaps; it is a serious, technically oriented book written by one of the world's leading experts on computer risks. The book summarizes many real events involving computer technologies and the people who depend on those technologies, with widely ranging causes and effects. It considers problems attributable to hardware, software, ...
Shaping Ecology
Sir Arthur Tansley was the leading figure in ecology for the first half of the 20th century, founding the field, and forming its first professional societies. He was the first President of the British Ecological Society and the first chair of the Field Studies Council. His work as a botanist is considered seminal and he is recognized as one of the giants of ecology throughout the world. Ecology underpins the principles and practices of modern conservation and the maintenance of biodiversity. It explains the causes of, and offers solutions to, problems of climate change. Yet ecology is a young science, barely 100 years old. Its origins lie in phytogeography, the naming and mapping of plants. ...
