Sound is usually treated as the most familiar of physical phenomena, the background noise of daily life rather than a frontier of fundamental physics. Yet in laboratories around the world, carefully ...

From our vantage point here on Earth, stars twinkle because our atmosphere warps light passing through it. When astronomers look through telescopes orbiting above Earth’s atmosphere, like Hubble and ...

The acoustic properties of an ultracold fermion gas have been measured either side of the superfluid transition temperature in an experiment that has been described as “near perfect” and “beautiful”.

The film explores the properties of sound waves in air, demonstrating that sound travels at approximately 1,100 feet per second and reflects similarly to light. Through experiments using echoes, beams ...

I love this art project. It’s called 20Hz and it uses data collected by the CARISMA radio array to turn the solar wind sound into beautiful threedimensional waveforms. Mesmerizing. [Lighthouse via The ...

A research team at City University of Hong Kong (CityU) has discovered a new type of sound wave: the airborne sound wave vibrates transversely and carries both rotation and orbital angular momentum ...
