(PhysOrg.com) -- While the optical laser celebrated its 50th anniversary earlier this year, some scientists have been working on a new type of coherent beam amplifier for sound rather than light. Scientists theorize that ...
Physicists in Darmstadt have been able to stop something that has the greatest possible speed and that never really stops. We're talking about light. Already a decade ago, physicists stopped it very for a short moment. In ...
