The Chandler wobble or Chandler variation of latitude is a small deviation in the Earth's axis of rotation relative to the solid earth, [1] which was discovered by and named after American astronomer Seth Carlo Chandler in 1891. It amounts to change of about 9 metres (30 ft) in the point at which the axis intersects the Earth's surface and has ...
The amplitude of the Chandler wobble, however, varies by a factor of three, and its frequency by up to 7%. Its maximum amplitude during the last 100 years never exceeded 230 mas. The Chandler wobble is usually considered a resonance phenomenon, a free nutation that is excited by a source and then dies away with a time constant τ D of the order ...
Modern polar wander can be evaluated from precise measurement using stars or satellite measurements, however filtering to remove the Chandler wobble of the Earth is required. The formation of supercontinents could initiate a faster polar wander. That is, because the supercontinent creates an extra mass concentration where they are located, the ...
The “Chandler Wobble” – a natural shifting of the Earth’s axis due to the planet not being perfectly spherical – could be linked to the spinning speeds, timeanddate.com reported.
Earth also has an additional 0.10 to 0.15 seconds of arc nutations with a period 6 and half years called Chandler wobble and its due to free nutation caused by irregular distribution of mass around Earth axis. [4]

Rotation and Interior Structure Experiment (RISE) is a radio science experiment onboard InSight Mars lander that will use the spacecraft communication system to provide precise measurements of Mars' rotation and wobble. RISE precisely tracks the location of the lander to measure how much Mars's axis wobbles as it orbits the Sun.
Chandler has to at least consider the possibility that McGregor will never fight again. The man certainly doesn’t need to. Depending on the severity of the injury and the appeal of any other ...
