The weak gravitational pull on a particle just half the mass of a grain of sand has been measured for the first time. This most precise measurement of its kind is a breakthrough towards the quantum ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I ...

If scientists had sacred objects, this would be one of them: a single, closely guarded 137-year-old cylinder of metal, housed in a vault outside of Paris. It is a prototype that precisely defines a ...

For scientists, the story of metrology has a simple plot: to ensure that standards keep improving. The pound of Imperial France made way for the platinum Kilogram of the Archives in 1799. In 1889 it ...

A method for characterizing quantum measurement devices completes the suite of 'tomography techniques', which should enable us to learn all there is to know about a given quantum-physics experiment. A ...

Deluged by responses to his request for your favourite units, Robert P Crease discovers that non-SI units persist, and are sometimes even popular, among the physics community Setting the standard ...

Physics is one of the core subjects in the JEE (Main) Examination. Students must be thorough with the physics syllabus to be aware of the potential questions that can be encountered in the JEE (Main) ...

When it comes to measuring things, there are some odd units of measurement out there. While measuring in feet is standard, there are many weirder ways to measure. Did you know a hand is a unit of ...
