A team of researchers studying the uncertainties associated with a phenomenon known as cosmic birefringence has developed a ...

Offering high-quality accurate measurements in a single device can improve performance and reduce cost. Measuring torque, rotational speed, angle of rotation, and the quantities derived from these ...

Astronomers using NASA’s Hubble Space Telescope have measured the rotation rate of an extreme exoplanet by observing the varied brightness in its atmosphere. This is the first measurement of the ...

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 ...

Angle of rotation: A light source (left) sends a beam of light through a topological insulator with an intrinsic magnetic field (centre), changing the direction of polarization by an angle that is ...

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 ...

Honda Motor has been granted a patent for a control apparatus that corrects errors in the angle measurement of a rotor in an electric motor. The apparatus determines whether a correction process has ...
