NASA’s TRACERS mission begins early science measurements in Earth’s southern polar cusp, tracking magnetic reconnection and ...

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 ...

Scientists are testing a novel way to measure cosmic expansion using time delays in gravitationally lensed quasars. Their results match “local” measurements but clash with early-universe estimates, ...

(a) By keeping the temperature ratio between the hot and cold baths constant, varying the energy level spacing of the working substance allows the quantum engine to operate in different thermodynamic ...

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 ...

Metrology is the science of precise measurement. It ensures accuracy and consistency across scientific, industrial, and engineering fields. Calibration is the process of aligning measurement ...

In no field of science is the gulf between appreciation and importance as wide as it is for metrology. It’s not about the weather. Metrology is the science of measuring. It has a longer history than ...

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 ...

Long-term, continuous measurements in science are rare. Most grants for scientific research only last a few years. To measure for longer, say hundreds of years, requires a different motivation.
