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 ...

This is a very popular video on the internet right now. It shows this awesome set up that uses sound to levitate very low density and small objects. I think this is a great opportunity to talk about ...

Can you imagine sound travels in the same way as light does? A research team at City University of Hong Kong (CityU) discovered a new type of sound wave: the airborne sound wave vibrates transversely ...

The earliest scientists first observed the waves that earthquakes produce before they could accurately describe the nature of earthquakes or their fundamental causes, as discussed in Lessons 1–5.

Forget superconductors and magnetic fields. Scientists from the University of Tokyo have developed a way to use sound waves to levitate objects and move them around midair. When a sound wave travels ...
