I just received my March copy of Physics Today. In there I found two articles I look forward to reading as soon as possible. The first is "Adjusting the Values of the Fundamental Constants" by Peter J. Mohr and Barry N. Taylor. Both authors are at NIST. Peter Mohr is currently the chairman of CODATA; Barry Taylor is the previous chairman and is also the head of the Fundamental Constants Data Center of the NIST Physics Laboratory. Barry has represented the U.S. on the Consultative Committee on Units at the CGPM. The second article is "Time Measurement at the Millenium" by James C. Bergquist, Steven R. Jefferts, and David J. Wineland. All three work in the time and frequency division of NIST. According to the brief description in the table of contents, it reports that the latest clocks use a single ion to measure time with an anticipated precision of one part in 10^18. Your public library may carry Physics Today. Jim -- James R.
