A new type of gyroscope based on interfering atoms has been developed that can determine the latitude where the instrument is located – and also measure true north and the Earth’s rate of rotation.

A protractor is used to draw and measure angles. An angle is the amount of turn between two lines. Angles are measured in degrees with the symbol °. Angles can be labelled with 3 letters (eg DEF) to ...

Spinning around: physicists have measured the effect of rotation on a quantum spin embedded in a diamond. (Courtesy: iStock/Gizmo) The effect of rapid rotation on a single quantum spin in a piece of ...
