Radar is quite spectacular in telling us exactly where rain is falling by pinging precipitation with radio waves! Our weather radar can determine more than just a storm’s location, but its movement as ...

The International Isle of Man TT is a crazy motorcycle race. I mean—it's seriously ludicrous. They ride on public roads (yes, they are closed to normal traffic) such that you get these videos of bikes ...

The Doppler effect is an observed change in pitch (how high or low a sound is) when either the source of the sound or the listener is in motion. Imagine a car, its horn blaring, approaching you as you ...

The Doppler effect, discovered in 1842 by Christian Doppler, is familiar to most of us; stationary observers of waves such as sound waves will see wavelengths that depend on the relative motion ...

A video of scientists dropping ice into a really deep hole has gone viral because of the wobbly cartoon-spaceship sound the falling ice makes. Princeton University geochemist John Andrew Higgins ...

Finding out how fast and in what direction a stellar object is moving relative to us involves the Doppler effect and the reading of absorption lines. The change in pitch you hear when a car speeds by ...
