For a qualified optomechanical analysis of lens systems, centration measurements are the standard approach – especially when precision lenses with tight tolerances need to be checked for quality ...

We know Earth’s rotation on a cosmic scale, but seeing it close up requires quantum mechanics. Interferometry is the use of light waves, sound, etc., to identify changes in matter or motion. New ...

Scientists have just plotted changes in Earth's axis through laboratory measurements. To do this, they constructed the world's most stable ring laser. Previously, scientists were only able to track ...

An innovative X-ray telescope operated by NASA, working in concert with a European Space Agency satellite, has directly measured the rotation of a supermassive black hole lurking at the heart of a ...

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.

This somewhat odd-looking apparatus is being used to measure earth’s rotation. At the heart of the system is a PlayStation Move controller, used because of its dual-axis gyroscope which has 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 ...

The Earth wobbles. Like a spinning top touched in mid-spin, its rotational axis fluctuates in relation to space. This is partly caused by gravitation from the sun and the moon. At the same time, the ...
