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 ...

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 ...

Entomologists and mechanical engineers ordinarily have little to do with one another. The first study bugs; the second design machinery. But last week the Sperry Gyroscope Co., designers of highbrow ...

A gyroscope is any rotating body that exhibits two properties: gyroscopic inertia or rigidity in space and precession or the tilting of the axis at right angles to any force tending to alter the plane ...

Traditionally, gyroscopes were mechanical devicesthat measured the angular rate of rotation. Onecommon use of gyroscopes has been in navigationsystems to provide heading estimation.Installing these ...

Some days really are longer than others. And now scientists know by precisely how much. Using a laser gyroscope, scientists have measured variations in Earth’s rotation rate smaller than a millionth ...
