"When the two light beams meet up, they greet each other like long-separated friends and continue on as if nothing had separated them. In other words, if we were to measure the properties of the ...

Researchers in Italy are hoping to measure Earth's rotation using a laser-based gyroscope installed deep underground, with enough experimental precision to reveal measurable effects of Einstein's ...

Accurately sensing rotation is important to a variety of technologies, from today's smartphones to navigational instruments that help keep submarines, planes, and satellites on course. In a paper ...

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 ...
