I am writing with regard to two letters (C&EN, Oct. 23, pages 4 and 6). One, by Oswald Bergmann, asks if global warming should be self-limiting according to Stefan-Boltzmann law. The simple answer is ...

In this video we'll take a look at thermal radiation, one of the three modes of heat transfer along with conduction and convection. We'll start by covering electromagnetic waves, the Stefan-Boltzmann ...

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, ...

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 ...
