(Phys.org) —A team of researchers in Korea has discovered a way to allow sound to pass through walls almost as if they were not there at all. As the group describes in their paper published in the journal Physical Review ...
(Phys.org)—In science, just like in life, sometimes creating the most effective organization depends on being able to handle just a bit of chaos first.
