Concurrent with the National Institute of Standards and Technology
(NIST) centennial, the NIST Physics Laboratory has issued a new chart of
the best available values for more than 100 of the most widely used
fundamental constants in physics and chemistry. A thorough and handy
reference for teachers, students, and researchers, the chart summarizes
the most recent recommended values from the Committee on Data for
Science and Technology (CODATA) that was established in 1966 by the
International Council of Scientific Unions to improve the quality and
reliability of key data in all fields of science and technology. CODATA
values are developed after a thorough review and examination of the best
available experimental measurements, observations, and calculations. The
new CODATA Recommended Values wall chart (NIST SP-961) is available in
two sizes: 17 by 22 inches and 8.5 by 11 inches (English dimensions
reflect the standard paper sizes in U.S. printing). An abbreviated set
of the constants is available on a wallet c ard (NIST SP-959). To
request copies, contact inquiries@nist.gov; 301-975-6478; or Fax
301-926-1630. A complete list of the recommended values of the
fundamental constants of physics and chemistry is available at
