Heat is not supposed to behave like this. In everyday life, warmth seeps and diffuses, spreading from hot to cold in a slow, smearing process that never looks anything like a crisp sound wave. Yet ...

Physicists at MIT have achieved a major feat, capturing a bizarre quantum effect called second sound on film, where heat ripples through matter like a wave instead of spreading gradually. First ...

Superfluid helium exhibits a range of remarkable physical phenomena that challenge conventional fluid dynamics and heat transfer theories. At temperatures near absolute zero, helium transitions into a ...
