Physicists have proposed a thermometer based on quantum entanglement that can accurately measure temperatures a billion times colder than those in outer space. Physicists from Trinity College Dublin ...

How do you take the temperature of a cell? The familiar thermometer from a doctor’s office is slightly too big considering the average human skin cell is only 30 millionths of a meter wide. But the ...

The original version of this story appeared in Quanta Magazine. If there’s one law of physics that seems easy to grasp, it’s the second law of thermodynamics: Heat flows spontaneously from hotter ...

To operate fusion systems safely and reliably, scientists need to monitor plasma fuel conditions and measure properties like ...

Physicists in the US have developed a new kind of thermometer that can measure down to as low as one billionth of a degree above absolute zero and has the potential to reach just a few trillionths of ...

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 ...

One of the most striking features of quantum physics is that certain properties cannot be measured at the same time. Every measurement may inevitably affect the object's physical state being ...

Radiation pressure force is exerted on a surface when it is struck by electromagnetic waves, such as light. Over the past few decades, physicists have used light’s radiation pressure to manipulate the ...
