How often are the fundamental constants of physics updated and by whom?
The recommended values of the fundamental constants are produced by the CODATA Task Group on Fundamental Constants the most recent evaluation was in 1998[1] previous evaluations were in 1986 and 1973. The first constants evaluation was that of Birge in 1929. It is hoped that modern computers and electronic distribution will allow the evaluations can be more frequent in future. See the NIST constants webpage for values and for more details. • Mohr, P.J. and B.N. Taylor, CODATA recommended values of the fundamental physical constants: 1998. Reviews of Modern Physics, 2000. 72(2): p. 351-495.
