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 ...

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 ...

Most aircraft carrying Doppler radar look like they've grown a tail, developed a dorsal fin, or sprouted a giant pancake on their backs. But when the unmanned Global Hawk carries a radar system this ...

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 ...

Doppler ultrasound blends physics and medical imaging to reveal the movement of blood through vessels and the heart. From diagnosing clots to assessing heart valve function, it’s a non-invasive tool ...

Reporting in Nature Physics, Luyi Yang and colleagues 5 now add the missing component, and provide the first quantitative answers to the question of how electronic spins drift, diffuse and precess in ...
