Shake a metal plate covered in sand at certain frequencies and intricate patterns mysteriously appear. Jon Jacobsen, a mathematician at Harvey... Vibrations Visualized With Sand And Sound Shake a ...

Researchers have created a nanoscale crystal device that, for the first time, allows scientists to confine both light and sound vibrations in the same tiny space. Researchers at the California ...

Singing sands, a centuries-old mystery, are explained by physics as dry dunes emit audible sounds when grains slide. Uniformly sized grains create synchronized vibrations, producing sustained musical ...

Certain desert dunes produce a deep, steady sound. This phenomenon occurs when dry sand slides down a dune's steep slope. Millions of grains move together, creating a low-frequency hum. This requires ...

Shake a metal plate covered in sand at certain frequencies and intricate patterns mysteriously appear. Jon Jacobsen, a mathematician at Harvey Mudd College, explains why this 200-year-old ...
