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 ...

In this episode of the Physics World Weekly podcast we celebrate the 100th anniversary of Measurement Science and Technology, which is the world’s first scientific instrumentation and measurement ...

The atomic clock comes in many varieties. Some are chip-sized electronics, developed for the military but available commercially now, while bigger and more accurate atomic clocks keep track of time on ...

Indian scientists have developed a non-invasive technique that allows real-time measurement of the local density of ...

Although most modern organisations possess extensive data, a subtler challenge persists: a lack of understanding regarding ...

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 ...

Edward Vicenzi is a guest researcher at the National Institute of Standards and Technology in the Material Measurement Laboratory. Christine France and Thomas Lam do not work for, consult, own shares ...

Scientists love precision. They can measure the distance from Earth to the moon to within a couple of centimeters and the spins of far-off pulsars to fractions of a millisecond. When peering inside a ...

Through randomly selected measurements, physicists can determine the quantum entanglement of many-particle systems. With the newly developed method, quantum simulations can be extended to a larger ...
