Across the world, decisions on investment and policy are made under the assumption of continuous economic expansion. Fundamental physical limits may soon put an end to this phase of development, as foreshadowed by the 1972 report The Limits to Growth.
The impact of legal metrology often remains unnoticed in our everyday lives. Pavel Klenovsky, Marc Wouters and Wilfried de Waal instruct us in trade and legal regulations.
Emerging quantum technologies pose new measurement challenges, but also offer previously unknown measurement solutions. National metrology institutes are playing a leading role in this fast evolving world.
As we celebrate the ten-year anniversary of the discovery of the Higgs boson, CERN’s Director-General at that time reminisces about the years leading up to this milestone.
The shift of the definition of the kilogram in 2019 away from an artefact to one relying on the Planck constant inspires technological innovation, as Naoki Kuramoto elucidates.
Against the backdrop of various philosophical accounts, this Comment argues for the need of a human rights approach to scientific progress, which requires us to rethink how we view scientific knowledge.
As conventions in scholarly publishing evolve, it is appropriate to reassess the options that we provide to our authors. In this spirit, Nature Physics will soon stop accepting submissions in our Letter format.
