The Sagnac effect, first observed over a century ago, remains central to our understanding of relativistic kinematics and the operational definitions of simultaneity. Fundamentally, this effect arises ...

One of the most basic structural aspects of relativistic spacetime is the description of how time and distances are altered by motion. The theory of special relativity describes a spacetime framework ...

The article was posted online by Nature Photonics on October 19 and can be found here: https://www.nature.com/articles/s41566-018-0266-5 Gyroscopes are devices that ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...

Forward-looking: Future electronics still have room to get a lot smaller. New techniques for creating optical gyroscopes may make motion and orientation detection significantly better all while chips ...

The California Institute of Technology has developed the world’s smallest optical gyroscope. The gyroscope is 500 times smaller than current devices, but it can detect phase shifts that are 30 times ...

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 ...

A new tiny optical gyroscope fits on the tip of your finger and could find its way into drones and spacecraft in the future. Gyroscopes are devices that help vehicles, drones, and wearable and ...
