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 ...

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 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 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 can be heard particularly clearly when a train passes by. The presence of the same effect in the generalised telegraph equation indicates the wave nature of heat transport over ...

Forbes contributors publish independent expert analyses and insights. I cover the history of science and exploration. Today's Google Doodle celebrates the 214th birthday of Christian Doppler, whose ...

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 ...

Queensland University of Technology provides funding as a member of The Conversation AU. When an ambulance passes with its siren blaring, you hear the pitch of the siren change: as it approaches, 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 ...

Figure 1: Illustration of the rotational Doppler effect in the linear and nonlinear optical regime. Compared with the rapid development and applications of the rotational Doppler effect in linear ...

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 ...
