Scientists in Germany have succeeded in re-determining the Boltzmann constant. Physicists expect that in the next two years they will be able to reduce the uncertainty to such an extent that a ...

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 ...

Scientists have performed the most accurate measurement yet of the Boltzmann constant. While the impact of such an achievement is not immediately obvious, the measurement could revolutionize the way ...
