Did you know that, at a certain point on a moving wheel... there's no motion? Did you know that, at a certain point on a moving wheel... there's no motion? I mean, kinda... it's all relative, right?

It has been one hundred years since the publication of Einstein's general theory of relativity in May 1916. In a paper recently published in EPJ Plus, Norwegian physicist Øyvind Grøn from the Oslo and ...

A detailed experimental analysis explains the forces by which a spinning magnet can cause another magnet to levitate in midair. An experiment with off-the-shelf components uses a magnet glued to the ...

It has been one hundred100 years since the publication of Einstein's general theory of relativity in May 1916. Physicists have now demonstrated that the rotational motion in the universe is also ...

Earth’s polar motion refers to the gradual wandering of the planet’s rotation axis relative to its crust. This motion is driven by the redistribution of mass and angular momentum within the solid ...

Almost all measurements of motion in astronomy make use of a law of physics called the Doppler effect. This change in the wavelength (or frequency, color, or pitch) of a wave emitted by a moving ...

A nuclear engineer reacts to XKCD’s question about whether driving west can extend a sunset, exploring the physics behind ...
