Time can mean many things, but Hillis's machine needs to track a particularly messy version: Earth - surface clock / calendar time, which is based on a byzantine agglomeration of astronomical rotations, orbits, and perturbations of hugely varying lengths, overlaid with arbitrary cultural whims about how to divide it up.

An analysis of recent measurements indicates that one of the main nonuniformities of the earth's rotation - its tendency to wobble gently about its rotation axis - may be excited by major earthquakes

By the 1920s, scientists like Edwin Hubble were cataloging thousands of «island universes» and recording information about their sizes, rotations and distances from Earth.

Shadow walls — where suspended panels with cutout images cast shadows as the sun shines through the cutouts — teach students about the earth's rotation and seasonal cycles as shadows cast by the sun shift positions and lengths.

If Galileo Galilei had lived to see his once controversial 17th - century theory about the Earth's rotation around the sun proven true, I expect he would know something like the joy I'm experiencing today.

According to a very apt reviewer on Doodling's Kindle store page, at first glance the book seems like a pleasantly silly story about a man flinging off the Earth's surface quite by mistake as the planet's rotation begins to spin out of control, forcing him to set up hearth on an asteroid.

As for melting continental ice sheets, yes, that would increase the Earth's moment of inertia about its axis of rotation, leading to a slight increase in length of day.

Jupiter does not disturb Earth's rotation about the Sun any more than does the Sun disturb the Moon's rotation about Earth, at least qualitatively.

Sidorenko tells about the factors that affect Earth's rotation, both that short term variability is largely due to changes in the atmospheric air movements and ocean currents, and that the decades - long fluctuations have another source, speed of drift of the lithosphere.

Our planet as a whole conserves its angular momentum except for the known effects of external torque associated with the lunar - solar tide, which induces a gradual decelerating of the earth rotation velocity at a rate corresponding to the increase in the astronomic length of day (LOD) by about 1.4 millisecond per century (Munk and McDonald 1960).

The climate and weather at a location are fundamentally set by the relationships between the geometry of the earth, the geometry of the revolution of the earth around the sun, the relationship between Earth's axis of rotation and the plane of Earth's orbit, and the rotation of the earth about its earth, the geometry of the revolution of the earth around the sun, the relationship between Earth's axis of rotation and the plane of Earth's orbit, and the rotation of the earth about its earth around the sun, the relationship between Earth's axis of rotation and the plane of Earth's orbit, and the rotation of the earth about its Earth's axis of rotation and the plane of Earth's orbit, and the rotation of the earth about its Earth's orbit, and the rotation of the earth about its earth about its axis.
