Lr. Pendrill, SOME COMMENTS ON FUNDAMENTAL CONSTANTS AND UNITS OF MEASUREMENT RELATED TO PRECISE MEASUREMENTS WITH TRAPPED CHARGED-PARTICLES, Physica scripta. T, T59, 1995, pp. 46-52
Precise measurements of various physical quantities are being made wit
h a much improved precision in experiments with trapped charged partic
les, many of which are reported in this Nobel symposium. In the presen
t paper, these and other precise measurements are placed in the wider
context of the successively more accurate determination of the fundame
ntal physical constants which has taken place during the last decades.
The role of systems of units of measurement, based on physical consta
nts and the most accurate measurements, is recalled in providing a coh
erent framework in which the results of experiments made on different
occasions and in different fields of physics may be related to one ano
ther.
