This bibliographic guide offers users a basic overview of the current trends and the best, most important, and most up-to-date paper and electronic information resources in the field of physics. The author has selectively chosen and succinctly annotated a list of hundreds of major tools used by physical scientists and researchers, including bibliographic sources, abstracting and indexing databases, journals, books, online sources, and other subject-specific non-bibliographic tools. Stern also provides information on grants, personal bibliographic database tools, document delivery, copyright and reserves. In addition, he discusses future developments, directions, and trends in the field, and in the concluding chapter he outlines the history and developments of the physics. Designed to help students, new researchers in the field of physics, and working physicists in need of additional information resources outside their normal field of study, this is an invaluable reference, research, and collectio

Computer Generated Physical Properties offers the environmental scientist a basis to predict the properties of molecules and reengineer them to remove those properties that are harmful to the environment. This technology is currently used in other fields and is now becoming popular in the environmental engineering field because of its pollution prevention and waste reduction capabilities. This book, interdisciplinary in scope, treats the physical properties of matter as generated by computers. It covers a wide variety of topics pointing towards synthesizing new molecules to substitute for reactants, intermediaries, and products in industrial processes with better physical and environmental properties than the original. The author achieves this with a spreadsheet program called SYNPROPS that operates on a PC computer with optimization features. A radar type graph - one for each property - visually sorts the various groups in order of their contribution to the property, creating the necessity for a computer to obtain answers for the structure of the optimum molecules for substitution or synthesis. The author discusses applications to biologically active molecules without side effects, including antineoplatic drugs. Additionally, he demonstrates model compounds and the applications of SYNPROPS' optimization and substitution. This book has everything you need to know about deriving properties and combinational chemistry from molecular structure.

"Highly recommended for anyone in chemistry looking for a very readable book on chemical information retrieval." -Journal of the American Chemical Society (on the Second Edition) The Essential Guide to Using CHemical Information Sources-in a brand-new Third Edition More chemical information resources exist now than ever before, in an array of formats that can be daunting to novices and experts alike in every discipline of the field. Yet a sound working knowledge of available sources and how to access them is an invaluable asset to anyone working in the fast-moving world of modern chemistry-an essential tool for saving time, money, and effort. This new edition of How to Find Chemical Information guides readers skillfully through today's complex maze of chemical information sources and systems, whether in electronic or printed form. It combines an in-depth examination of chemical information tools and access methods with tested principles for assessing and selecting the most appropriate sources for different needs. Thoroughly revised and updated to address all major developments and trends of recent years, How to Find Chemical Information, Third Edition is a peerless resource that features: * The mechanics of chemistry information flow, communication patterns, and search strategies * Detailed and up-to-date material on Chemical Abstracts Service and its products * Other private and government chemical information sources * Online databases, host systems, Internet files, CD-ROMs, and other electronic products and how these fit into the total information picture * Encyclopedias, other major reference books, and reviews * Journals and patent documents * Coverage of safety, the environment, and related topics * Chemical marketing and business resources * Physical property data, process information, and more

It is usually straightforward to calculate the result of a practical experiment in the laboratory. Estimating the accuracy of that result is often regarded by students as an obscure and tedious routine, involving much arithmetic. An estimate of the error is, however, an integral part of the presentation of the results of experiments. This textbook is intended for undergraduates who are carrying out laboratory experiments in the physical sciences for the first time. It is a practical guide on how to analyse data and estimate errors. The necessary formulas for performing calculations are given, and the ideas behind them are explained, although this is not a formal text on statistics. Specific examples are worked through step by step in the text. Emphasis is placed on the need to think about whether a calculated error is sensible. At first students should take this book with them to the laboratory, and the format is intended to make this convenient. The book will provide the necessary understanding of what is involved, should inspire confidence in the method of estimating errors, and enable numerical calculations without too much effort. The author's aim is to make practical classes more enjoyable. Students who use this book will be able to complete their calculations quickly and confidently, leaving time to appreciate the basic physical ideas involved in the experiments.
