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 ...
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 ...
The world’s measurement system will be based on updated values for four fundamental constants of nature. A revised SI ( the International System of Units ) based fully on accurate values of these ...
