Quantum physicists have uncovered a bizarre phenomenon in which photons appear to spend a “negative” amount of time ...

Well, science and baseball. Physicists build models to explain how the world works. It might be an equation, like the ideal ...

Many volatile organic compounds (VOCs) are potentially harmful to the environment and people, so it’s useful to know when they are present. These authors developed a method to identify VOCs that ...

The number-one job of a marketer is to invest budget wisely to drive sales. That inherently requires accurately measuring the performance of that spending. Yet most advertisers still rely on flawed ...

Scientists have announced the results of a decade-long quest to measure Newton’s gravitational constant, the force that keeps our feet on the ground and holds planets in orbit. The pursuit was more or ...

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...

I was watching Ben Krasnow making iron nitride permanent magnets and was struck by the fact that about half of the video was about making a magnetometer – a device for measuring and characterizing the ...

Scientists have measured 'negative time' in a quantum experiment, where photons appeared to exit a rubidium atom cloud sooner than physically expected. Using weak measurement techniques, the team ...

Physicists have just dropped a new precise measurement for gravity. The newly published value for the strength of gravity, known as “G” or “Big G”, is significantly smaller than some previous ...

Improvements to the SI are helping to evolve the science of accuracy and measurement. Democratization of the SI creates a traceability calibration chain accessible to anyone, anywhere. Digitization of ...
