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 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 ...

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 inverse Doppler effect has been observed in an experiment for the first time. Nigel Seddon and Trevor Bearpark at BAE Systems in Bristol in the UK saw the effect in an electrical transmission line ...

The Doppler Effect is physics that is so ingrained in our brain that even the movies get it right. Any time some character is walking down a street and a car or train rushes past, the sound of the ...

The headline is somewhat of a trick question: of course the effect did exist before the railroads. However, it wasn’t yet defined by the physics of the day, nor was it even noticed before the ...

Physicists have generated a lot of excitement in recent years by dreaming up specially structured materials with novel applications like invisibility cloaks. What’s more, some of these “metamaterials” ...

A twist on the physics that cops use to clock speeding drivers can determine how fast an object is spinning. The approach could be used to protect wind turbines from damaging winds, learn about ...

MADISON — 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 ...
