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 ...

Researchers at Hiroshima University have developed a realistic, highly sensitive method to detect the Unruh effect—a ...

The world of quantum physics is already mysterious, but what happens when that strange realm of subatomic particles is put ...

With a dedicated monthly column, Nature Physics draws attention to metrology. And a set of Commentaries in this issue focuses on various aspects of thermometry. Physics is all about observations, ...

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 ...

Physicists have devised a thermometer that can potentially measure temperatures as low as tens of trillionths of a degree above absolute zero. As physicists strive to cool atoms down to ever more ...

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 ...

In my review of the FLIR One, I mentioned that this would be an excellent device for a physics lab. So, here is my first "lab", hopefully there will be more posts like this. The FLIR One Tech Specs ...

Measuring temperature turns out to be a fundamental function for a huge number of devices. You furnace’s programmable thermostat and digital clocks are obvious examples. If you just needed to know if ...
