But there’s a problem. While it’s a simple matter to build mirrors and beam splitters for photons, it’s extremely difficult to do that for matter waves. As a result, matter-wave interferometers are ...

(PhysOrg.com) -- When a spinning laser gyroscope is placed near a super-cooled rotating ring, the gyroscope accelerates a bit in the same direction as the ring, and scientists aren’t sure why. The ...

Gyroscope designs used in inertial navigation systems (INS) fall into three basic groups: the classic spinning-rotor mechanical gyro (still in use in specialized situations due to its superior ...
