Physical and Biophysical Chemistry
Quantities, Units and Symbols in
The purpose of this manual is to improve the exchange
of scientific information among the readers in different disciplines
and across different nations. As the volume of scientific literature
expands, each discipline has a tendency to retreat into its own jargon.
This book attempts to provide a readable compilation of widely used
terms and symbols from many sources together with brief understandable
definitions. This Third Edition reflects the experience of the contributors
with the previous editions and we are grateful for the many thoughtful
comments we have received. Most of the material in this book is "standard",
but a few definitions and symbols are not universally accepted. In
such cases, we have attempted to list acceptable alternatives.
The book has been systematically brought up to date
and new sections have been added. As in previous editions, the first
chapter describes the use of quantity calculus for handling physical
quantities and the general rules for the symbolism of quantities and
units and includes an expanded description on the use of roman and
italic fonts in scientific printing. The second chapter lists the
symbols for quantities in a wide range of topics used in physical
chemistry. New parts of this chapter include a section on surface
structure. The third chapter describes the use of the International
System of units (SI) and of a few other systems such as atomic units.
Chapter 4 outlines mathematical symbols and their use in print. Chapter
5 presents the 2002 revision of the fundamental constants (published
in 2005), and Chapter 6 the properties of elementary particles, elements
and nuclides. Conversion of units follows in Chapter 7, together with
the equations of electricity and magnetism in their various forms.
Chapter 8 is entirely new and outlines the treatment of uncertainty
in physical measurements. Chapter 9 lists abbreviations and acronyms.
Chapter 10 provides the references, and Chapter 11, the Greek alphabet.
In Chapter 12, we end with indexes.
