MIT Physicists Observe “Second Sound,” Confirming 1938 Prediction & Unlocking Quantum Heat Transfer
For nearly a century, physicists have theorized about “second sound” – a counterintuitive phenomenon where heat propagates as a wave rather than diffusing. Now, a team at MIT has achieved a breakthrough, directly observing this elusive effect in a quantum fluid. The findings, published in the journal Science, confirm predictions dating back to 1938 and … Read more
