sound waves cause air particles to vibrate back and forth ripples cause water particles to vibrate up and down Waves cause a disturbance of the medium through which they travel. This allows them to ...

As many believe, the Big Bang started our universe. But not everyone is aware that the early world is nothing like what we can see these days. There's no stars, planets, galaxies or nebulas. For a bit ...

Bloch oscillations are periodic oscillations of quantum particles in a repeating energy "landscape" (e.g., a crystal lattice) ...

The film explores the nature of sound waves, demonstrating how sound travels as a wave through air, which acts as a medium. It illustrates sound generation using a loudspeaker, examines oscillation, ...

Super-oscillation is a counterintuitive phenomenon describing localized fast variations of functions and fields that happen at frequencies higher than the highest Fourier component of their spectra.

Scientists have shown how gravitational waves -- invisible ripples in the fabric of space and time that propagate through the universe -- might be 'seen' by looking at the stars. The new model ...

Scientists have recently found that the temperatures in Saturn's equatorial atmosphere oscillate with a period of about 15 Earth years. The temperature swing's signal was detected by analyzing ...

ABSTRACT The North Atlantic Oscillation (NAO) response to the northeast Pacific climate variability is examined using the ERA-40 dataset. The main objective is to validate a mechanism involving ...

New research shows that equatorial waves -- pulses of warm ocean water that play a role in regulating Earth's climate -- are driven by the same dynamics as the exotic materials known as topological ...

New research shows that slow oscillations in the brain, which occur during deep sleep and anesthesia, are guided by neuronal excitability rather than structural anatomy.
