Drawing together leading experts from across the field, an international collaboration of cosmologists has created a unified approach for measuring the value of the Hubble constant. Published in ...

Hubble constant. The Hubble constant is crucial in understanding the rate of expansion of the universe and, by extension, estimating the universe’s age. This collaborative effort unites various ...

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 ...

(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 ...
