Buyers guide features NIST Data product. (General Developments).The lead article in the annual Buyer's Guide of the American Institute of Physics features five pages of values of the fundamental physical constants, such as the speed of light, the Newtonian constant of gravitation 1. The natural phenomenon of attraction between massive bodies. 2. The act or process of moving under the influence of this attraction. 3. A movement toward a source of attraction. Conversion factors Rules set by the Chicago Board of Trade for determining the invoice price of each acceptable deliverable Treasury issue against the Treasury Bond futures contract.. The guide was distributed as a supplement to the August issue of Physics Today, a monthly publication with a circulation of about 123 000 worldwide. The numbers published in the tables were obtained from the 1998 CODATA CODATA - Committee On Data for Science & Technology least-squares adjustment of their values carried out in the Fundamental Constants Data Center at NIST NIST - National Institute of Standards & Technology (US)NIST - National Industrial Security Program NIST - National Institute of Science and Technology NIST - National Intelligence Support Team NIST - Nonproliferation & International Security Technology Division in 1999. Other publications, such as the CRC Handbook of Chemistry and Physics, also quote the values obtained at NIST. Values of the constants can be found on the Web site at http://physics.nist.gov/constants. This site averages well over 100 000 downloads per month from outside of NIST. The Fundamental Constants Data Center also distributes wallet card and page-sized tables of values of the constants. These may be obtained from NIST at (301) 975-NIST (6478).
