he said. Because of the Doppler effect, the sirens have a higher pitch when they’re coming towards you and a lower one as they drive away. The change in pitch reflects the change in wavelength created by the siren. He didn’t stop there. He ...
In its nearly 30-year history, the space shuttle program has seen exhilarating highs and devastating lows. The fleet has taken astronauts on dozens of successful missions, resulting in immeasurable scientific gains. But this success has had a serious cost. In 1986, the Challenger exploded duri...

If you set up a bunch of speakers toimitatethe sound of a passing car, none of them are moving, so there will be no Doppler shift from the point of view of a stationary observer. You could create the same effect by deliberatelyaddingpitch shifts to the sound being played so that it s...

The Doppler effecthappens when a moving object emits something, in this case sound waves. When each new wave is emitted in front of the sound source, it's closer to the previous wave than it would have been if the emitter were stationary. Behind the emitter, each new wave is a bit fur...
Variomatic Transmission (Image Courtesy: YouTube) Fiat, Ford, and Van Doorne established this improvement in the Netherlands in the late 1970s. Besides, this transmission is also under electronic control. Transmatic is the version that incorporates the switch from rubber to steel belts. ...
This is the organization that is responsible for tracking US business cycles and calling “recessions.” There are two effects of robots, the authors point out: The “displacement effect” when robots eliminate jobs; and the “productivity effect” as other industries or tasks require more labor ...
Two sources of redshift: Doppler and cosmological expansion; modeled after Koupelis & Kuhn. Bottom: Detectors catch the light that is emitted by a central star. This light is stretched, or redshifted, as space expands in between. Credit: Brews Ohare. ...
To be able to do this squat and optimize its effect on distance, do you recommend having a higher backswing than having a flatter one? Log in to Reply Nathan Bone says: December 19, 2017 at 5:13 am Thanks man this really works Log in to Reply Ojvind Burgundur says: December...
