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 ...

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 ...

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 ...

To forge nanodiamonds, which have potential applications in medicine, optoelectronics and quantum computing, researchers expose organic explosive molecules to powerful detonations in a controlled ...

In an upcoming refresh, particle physics will define units of measurement such as the meter, the kilogram and the second. While America remains obstinate about using Imperial units such as miles, ...

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 ...

The famous thought experiment known as Schrödinger's cat implies that a cat in a box can be both dead and alive at the same time — a bizarre phenomenon that is a consequence of quantum mechanics. Now, ...
