Temperature is a pretty weird thing if you think about it. How do you best define temperature? Let me go ahead and give you my favorite definition: Temperature is the thing that two objects have in ...

A special type of laser spectroscopy has been used by researchers in Australia to measure the velocities of atoms in caesium vapour. The technique could allow researchers to infer both the temperature ...

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 ...

An abrupt transition in the electrical resistance of graphite at 350 K could be a signature of superconductivity occurring well above room temperature (293 K). That is the claim of Pablo Esquinazi and ...

Gold usually melts at 1,300 kelvins—a temperature hotter than fresh lava from a volcano. But scientists recently shot a nanometers-thick sample of gold with a laser and heated it to an astonishing ...
