One of the traditional activities of the National Physical Laboratory is its work on the maintenance and improvement of the primary standards of measurement. Although one may possibly visualise such work, because of its long history and its association with calibration services, as of a largely routine character, this is certainly far from the case at the present time. The present is a period of considerable activity and change in fundamental metrology, with the classical material standards of measurement being superseded by atomic or quantum standards. The past decade has seen a change to atomic standards for the units of length and time, and there seems little doubt that the future will see an extension of atomic-based standards to other areas, notably that of the electrical quantities. Some of the changes which may come about as a consequence of adopting the most accurate and convenient quantum methods have interesting implications. For example, a possible outcome of the new techniques being developed for the accurate measurement of very high (infrared) frequencies is that the standards of length and time may become unified, with the velocity of light taking the role of an agreed defined constant rather than an experimentally determinable quantity.

With today's current wave of quality consciousness, our quality control people tell us we MUST calibrate our instruments using standards that are traceable to the national laboratories (NIST - National Institute of Standards and Technology in the U.S.,. NPL - National Physical Laboratory in the UK, and others). But, is it really magnification that should be calibrated?While recently walking around the exhibit floor at the Microscopy & Micrcanalysis ‘98 Conference, I noticed the large SEM image display screens that now present our highly magnified specimens. Almost all vividly show a micron (using SI units this should be a “micrometer”) marker as well as the magnification. No doubt the accuracy is within the ± 3% that is commonly quoted by the manufacturers.

Good Measurement

We present here a summary of a workshop held 1-3 May 2018 at the National Physical Laboratory, Teddington, UK in which the focus was how the national metrology institutes of the world might help to address challenges in reproducibility of research. The workshop brought together experts from the measurement and wider research communities (Physical-, Data- and Life-sciences, Engineering, and Geology) to understand the issues and to explore how good measurement practice and principles can foster confidence in research findings [1, 2, 3], including how we can tackle the challenge posed by increasing data volumes in both industry and research. The workshop involved 63 participants from metrology laboratories (38), academia (16), industry (5), funding agencies (2), and publishers (2). The participants came from UK, US, Korea, France, Germany, Australia, Bosnia and Herzegovina, Canada, Turkey, and Singapore.
