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 ...

Circular thinking: light a ring laser has been used to measure the Earth’s rotation. (Courtesy: iStock/amtitus) A gyroscope sensitive enough to detect Earth’s rotation has been created using a ...

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 ...

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 ...
