When was the speed of earth's rotation first calculated? originally appeared on Quora: the place to gain and share knowledge, empowering people to learn from others and better understand the world.

Earth's axial precession, a slow wobble of its rotational axis, is analogous to the gyroscopic motion of a spinning top. The primary cause of Earth's precession is the gravitational influence of the ...

WASHINGTON, D.C., March 14, 2017 -- Researchers in Italy hope to measure Earth's rotation using a laser-based gyroscope housed deep underground, with enough experimental precision to reveal measurable ...

Toy gyroscopes can do all kinds of interesting tricks. The most mysterious one, precession, seems to defy gravity. By definition, precession refers to a change in the orientation of the rotational ...

Sensitive measurements: Ring laser at the Geodetic Observatory Wettzell in Bavaria. (Courtesy: Astrid Eckert / TUM) As the Earth moves through space, it wobbles. Researchers in Germany have now ...

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.

AN interesting dynamical illustration of the Zeeman effect may be made by fixing a gyroscope so that its axis of rotation is the line of suspension of a pendulum bar so suspended as to be capable of ...

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