This book consists of material in the first chapter of A Physicist's Desk Reference, updated and supplemented by additional new data. It's a self-contained, quick reference guide to the most commonly used mathematical formulas, tables of data, symbols, units, standard nomenclature, and fundamental constants in physics. A useful bibliography to more complete sources of data is also included.

Market: Engineers, researchers, and students in vacuum science and materials science and designers and manufacturers of vacuum electronic devices in any field where glass, ceramics, refractory metals, and joining methods are used. The republication of this widely used handbook makes available again an invaluable source of fundamental information on the construction of vacuum devices and provides a complete rundown on the properties of basic materials used in vacuum tubes (glass, ceramics, mica, carbon, graphite, iron, steel, copper, nickel, precious metals, refractory metals, and all relevant alloys). Most importantly, it offers step-by- step guidelines for basic joining techniques, including how to deal with common problems such as secondary emission and voltage breakdown. High-temperature properties are emphasized in recognition of the crucial role of vacuum devices in space technology.

Market: Students and researchers in space and high-vacuum technology and materials science. This handbook was originally prepared so that workers would not have to consult a great many sources to learn what procedures and materials were used to construct tubes and other evacuated devices. Even now, as space and high-vacuum research are yielding new information daily, much of the subject matter in this seminal work, such as properties of materials, are as cogent as they were in 1964 when the book was first published.

Researchers, postgraduate and undergraduate students of high energy physics

All with an interest in physics and related technologies; those interested in the history of modern physics.

Papers comprising this volume were presented at the first IEEE Conference on [title] held in Denver, Co., Nov. 1987. As the limits of the digital computer become apparent, interest in neural networks has intensified. Ninety contributions discuss what neural networks can do, addressing topics that in
