Acoustic frequency filters, which convert electrical signals into miniaturized sound waves, separate the different frequency ...
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 ...
New methods of detecting ultra-low frequency gravitational waves can be combined with other, less sensitive measurements to deliver fresh insights into the early development of our universe, according ...
The Quarterly of Applied Mathematics contains original papers in applied mathematics which have a close connection with applications. An author index appears in the last issue of each volume. This ...

Perhaps the most iconic instrument in modern rock is the guitar. It's really just a bunch of strings stretched across a board, which you can strum to make awesome tunes, thanks to the physics of waves ...
Phonons are sound particles or quantized vibrations of atoms in solid materials. The Debye model, a theory introduced by physicist Peter Debye in 1912, describes the contribution of phonons to the ...
