This PSSC film made in 1960 is one of the finest physics films ever made. All students should see it at some point in their studies. See the article '"Frames of Reference" revisited' by Alistair Steyn ...

Shown below is an animation of the motion of A and B as seen by a stationary observer. The paths of A and B are straight, as expected, with the speed of B increasing in time. View of B as seen by an ...

Aircraft A and B are flying on the same horizontal plane, each with a constant speed. Aircraft A is traveling on a straight path, whereas the path of B is circular. We are interested in understanding ...

In an article published in Communications Physics, researchers from the Université libre de Bruxelles and the Institute for Quantum Optics and Quantum Information in Vienna present a new framework for ...

The surface of Earth is constantly being reshaped by earthquakes, volcanic eruptions, landslides, floods, changes in sea levels and ice sheets and other processes. Since some of these changes amount ...
