NIST 'noise thermometry' yields accurate new measurements of Boltzmann constant

Thursday, June 29, 2017 - 16:12 in Physics & Chemistry

By measuring the random jiggling motion of electrons in a resistor, researchers at the National Institute of Standards and Technology (NIST) have contributed to accurate new measurements of the Boltzmann constant, a fundamental scientific value that relates the energy of a system to its temperature. NIST made one measurement in its Boulder, Colorado, laboratory and collaborated on another in China.
