Scientists have detected the Doppler effect — a quirk of physics that makes an ambulance's siren change pitch as it drives by — on the scale of a single molecule. The Doppler effecthas been understood ...

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 shift of sound or light waves from a moving source is familiar to physicists and non-physicists alike. Now, researchers in China and Australia have seen the more exotic inverse Doppler ...

What if the speed of light is a constant only most of the time? What if gravity sometimes pushed instead of pulled? Scientists are increasingly asking what would seem like far-out questions regarding ...

Born Nov. 29, 1803, in Salzburg, Austria, Christian Doppler studied mathematics, physics, and astronomy at the University of Vienna. After struggling to secure an academic post and working as a ...

The autonomous and compact High-altitude Imaging Wind and Rain Profiler, or HIWRAP, a dual-frequency conical-scanning Doppler radar, will hang under NASA's aircraft's belly as it flies above ...

This is the fifth and final instalment of our “five amazing physics demonstrations” presented by science-demo guru Neil Downie and his adept assistant Matthew Isbell. In a special feature in the April ...
