The influence of time varying magnetic fields on the determinations of Newton’s constant at the Bureau International des Poids et Mesures
Autor: Clive C Speake, John L Bryant, Richard S Davis, Terry J Quinn
Publikováno v: Metrologia. 60:024001
The values of Newton’s constant of gravitation, G, reported by determinations at the International Bureau of Weights and Measures (BIPM) in Quinn et al (2001 Phys. Rev. Lett. 87 111101/1–111101/4) and in Quinn et al (2013 Phil. Trans. R. Soc. A 3

Note on Weighings Carried Out on the NBS-2 Balance
Autor: Richard S Davis, P Carré
Publikováno v: J Res Natl Bur Stand (1977)
The NBS-2 balance was designed and built at NBS and transferred to the BIPM in 1972. It is presently used for the comparison of national prototype kilograms with international standards. Excellent environmental conditions at the BIPM have resulted in

Recalculation of the Faraday Constant Due to A New Value for the Atomic Weight of Silver
Autor: Richard S Davis, T. J. Murphy, Vincent E. Bower, Paul J. Paulsen, L. J. Powell, J. W. Gramlich
Publikováno v: J Res Natl Bur Stand (1977)
A report of the Faraday constant as detennined at NBS via silver coulometry and atomic weight measurements is presented. The uncertainty of the reported result represents a five-fold improvement over measurements made at NBS 20 years ago. The result

Basic metrology: A matter of time
Autor: Richard S Davis
Publikováno v: IEEE Instrumentation & Measurement Magazine. 22:54-56
If measuring devices are extensions of our senses, then increasing measurement accuracy can improve our knowledge of the universe. This month's column is about some of the most accurate measurements known—time from atomic clocks—and how such meas

Basic metrology: It's elementary
Autor: Richard S Davis
Publikováno v: IEEE Instrumentation & Measurement Magazine. 22:29-31
We are now well into 2019, the International Year of the Periodic Table (IYPT), celebrating the 150th anniversary of pioneering work of Dmitri I. Mendeleev (1834-1907). He not only made sense of the zoo of chemical elements that were known in 1869 bu

Solar time versus time on our mobile phones
Autor: Richard S Davis
Publikováno v: IEEE Instrumentation & Measurement Magazine. 22:36-38
For the purposes of the following discussion, I define solar time as the time displayed on a carefully made sundial. I will then compare this to the time displayed on a mobile phone at the same instant, at the same location.
