Doppler radar stands as the most important modern invention in meteorology, fundamentally transforming how we predict, prepare for, and track severe weather events. Since installations began across ...

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 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 ...

With more and more cars driving themselves, there is an increasing demand for precise environment aware sensors. From collision avoidance to smooth driving, environmental awareness is a must have for ...

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 ...

[Daniel] stumbled on an interesting paper (which we featured before) on Doppler gesture sensing using only a computer’s speaker and microphone. Unfortunately the paper didn’t include source code so ...

Everyone has experienced the Doppler effect. An ambulance’s siren has a higher pitch as it approaches you, and a lower pitch when moving away. Now, imagine that the pitch goes down as the ambulance ...
