The use of sound in medicine started since long time ago. Doctors have used stethoscopes to listen to human body’s internal sounds since the early 19th century and the ultrasound imaging has develop ...

On today’s episode of “For Science!” we invite a very special guest to the lab, 9 & 10 chief meteorologist Michael Stevens to discuss the often misunderstood concept of Doppler. Many believe that the ...

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 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 ...

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” ...

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 ...

The Doppler effect refers to a noticeable change in frequency of light or sound waves as the distance between the source and the observer changes. It is either the source or the observer of a wave is ...
