For example, with classical reference frames, if you change your point of view from one frame to another, this transformation is reversible: you can revert to your original point of view.

In the above example, two quintessential properties of quantum systems — superposition and entanglement — turn out to depend on the frame of reference. “The main message is that a lot of the ...

Python Physics; Modeling an Exploding Spring in Different Reference Frames. Posted: June 2, 2025 | Last updated: June 2, 2025. Physics and Python stuff.

The unification of the theory of relativity and quantum mechanics is a long-standing challenge in physics. Here the authors investigate the effects of a wide range of accelerations on an entangled ...

In our train example, the two reference frames are the perspective of someone standing on the train, and someone standing on the platform. Neither reference frame is accelerating, so they're ...

Universal wonder Despite a society that told Chanda Prescod-Weinstein she didn’t look like a physicist, she still managed to fall in love with the subject as a child. (Courtesy: Shutterstock/Prazis ...

In physics, a frame of reference is an abstract co-ordinate system that uniquely fixes a point within a universe. That point is described in terms of location and orientation, but the universe itself ...

Physics models work great in inertial frames, and it doesn't matter which one you choose. Bob's reference frame with respect to the ground is no better or worse than mine in the moving train ...

Discover how Einstein’s theory of special relativity reshaped physics by linking space, time, mass, and energy in a universe governed by the speed of light.
