Collaboration Between NPL and NIST



K B. Gebbie


Since its inception in 1901, the National Institute of Standards and Technology (NIST) (then the National Bureau of Standards) has sought guidance from its sister institute, the National Physical Laboratory. For almost a century, the two institutions have enjoyed a synergistic and collegial relationship, which has produced some of the world's most important contributions to science and technology. The bonds forged between NIST and NPL are today as strong as ever and will surely continue into the future. The interactions between the two institutions span a wide range from intercomparisons of essential physical quantities that profoundly impact international commerce, to high-precision measurements of fundamental physical constants that push back the frontiers of science and spawn new technology. From atomic clocks to new realizations of mass standards, from early intercomparisons of lamps to recent developments in high-accuracy absolute cryogenic radiometry, from seminal developments.
