These results will contribute to a worldwide effort to redefine the kelvin, the international unit of temperature, and could lead to better thermometers for industry. Accurate temperature measurement ...

Researchers have for the first time used an apparatus that relies on the "noise" of jiggling electrons to make highly accurate measurements of the Boltzmann constant, an important value for many ...

In an upcoming refresh, particle physics will define units of measurement such as the meter, the kilogram and the second. While America remains obstinate about using Imperial units such as miles, ...
