CODATA recommended values of the fundamental physical constants: 2006

Peter J. Mohr, Barry N. Taylor and David B. Newell

This review of the fundamental constants provides recommended values and their associated uncertainties, updating the last review of 2002. Since that time, new data and methods have led to a significant reduction in the uncertainties of many previously recommended values. For example, the uncertainty of the fine structure constant α has been reduced by nearly a factor of five and the one of Planck's constant ℏ by over a factor of three. The outlook and suggestions given for future work will certainly spark several ambitious experiments from various groups.

CORRECTIONS

In the March APS News, in the Focus on the Topical Group on Gravitation on page 5, we placed one of the LIGO labs in the wrong state. The two LIGO laboratories are in Louisiana and Washington State.

In the April APS News, we incorrectly identified one of the people in a front-page photograph with the headline "Money Matters". The person on the right is DPB secretary-treasurer Stan Schriber.
