In a breakthrough that challenges conventional physics, scientists have confirmed the existence of “second sound” — a ...

MIT researchers observe a “second wave” of heat in superfluid helium, confirming that heat propagates like sound.

As the communication range increases, turbulence becomes a significant atmospheric process that affects the propagation of optical waves. This paper presents a more accurate NLOS channel model by ...

Understanding the relationship between the structure of a tornado-like vortex and how it transports debris can help curb its ...
