Time reversal techniques have emerged as a robust approach to manipulating acoustic and elastic waves by harnessing the time‐symmetry inherent in the wave equation. This methodology permits waves to ...

Physicists at MIT have created a time-reversal machine that can measure vibrating atoms. The vibrations between atoms hold a lot of information. And, if scientists can even figure out how to ...

While the concept of time travel has long captured public imagination, modern physics actually approaches time in a much more subtle manner. Instead of moving people or objects through history, ...
