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 ...

One of the stranger features of the quantum world is that light—even individual photons—can behave as a wave or a particle, depending on how you measure it. But, according to papers released by ...

Imagine a physicist observing a quantum system whose behavior is akin to a coin toss: it could come up heads or tails. They perform the quantum coin toss and see heads. Could they be certain that ...

NASA’s Earth Observing System provides nearly 30 years of continuous, high-quality measurements of Earth’s land, oceans, atmosphere, and ice, supporting climate research and long-term environmental ...

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 ...

Since July 2022, a miniature satellite about the size of a shoebox has been orbiting Earth and monitoring how much solar energy reaches the atmosphere. Now, scientists are finalizing their analysis of ...

Metrology, the branch of science dedicated to measurement, has created better and better systems of measurement for the kilogram based on fundamental principles rather than arbitrary chunks of metal ...

One of the most important—and famous—results in quantum mechanics is the Heisenberg Uncertainty Principle (HUP). What is less known (at least to non-physicists) is that the HUP exists in two versions.
