Rotational motion can feel tricky, but with the right approach, it becomes a powerful tool in your physics toolkit. From angular velocity to torque, understanding these concepts is key to solving real ...

All in a spin: Two indistinguishable photons (red lines) are incident on a beamsplitter cube and become entangled. The two photons are then coupled into an optical fibre-based interferometer, which is ...

For superfluid systems composed of electrically neutral particles (liquids, vapours or even solids 4) and for slow rotations, a fraction of the system, the superfluid fraction, remains irrotational.

A British physicist says his quantised inertia "new physics" theory explains galaxy rotation without the need for dark matter, further justifying his earlier work proving how the EmDrive works iStock ...
