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 ...

Physicists in the US have developed a technique that may help to make a more accurate measurement of the Boltzmann constant, a fundamental value that relates the kinetic energy of a group of particles ...

A NOISY ball of gas is now the most accurate thermometer ever. That removes one hurdle to redefining the scientific unit of temperature, the kelvin, in terms of a fundamental constant. At the moment, ...

The temperature of a substance, whether solid, liquid, gas or plasma, is essentially related to the speed at which its particles are moving in relation to each other. There is an upper limit on speed ...
