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 ...

The most accurate thermometer in the known universe looks nothing like a thermometer. It is a copper vessel the size of a large cantaloupe, filled with ultrapure argon gas and studded with microphones ...

A new measurement of a fundamental physical constant marks a turning point in the quest to craft a perfect temperature scale The most accurate thermometer in the known universe sits in a rather ...

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 ...

ABSTRACT In speleological environments, partial pressures of carbon dioxide (CO₂) are often large enough to affect overall air density. Excluding this gas when defining the gas constant for air, a new ...

Nothing is colder than absolute zero, so it seems nonsensical to talk about negative temperature – but now there is a substance that must have just that. The revelation could shake up our ideas about ...
