1. Physical constants1011. PHYSICAL CONSTANTSTable 1.1.Reviewed 2010 by P.J. Mohr (NIST). Mainly from the “CODATA Recommended Values of the Fundamental Physical Constants:2006” by P.J. Mohr, B.N. Taylor, and D.B. Newell in Rev. Mod. Phys.80(2008) 633. The last group of constants (beginning with the Fermicoupling constant) comes from the Particle Data Group. The ±gures in parentheses after the values give the 1-standard-deviation uncertaintiesin the last digits; the corresponding fractional uncertainties in parts per 109(ppb) are given in the last column. This set of constants (asidefrom the last group) is recommended for international use by CODATA (the Committee on Data for Science and Technology). The full 2006CODATA set of constants may be found athttp://physics.nist.gov/constants.See also P.J. Mohr and D.B. Newell, “Resource LetterFC-1: The Physics of Fundamental Constants,” Am. J.
