... Bad Astronomy . ... Every few months, one of a series of questions comes up on the USENET group sci.astro involving tides, or the rotation of the Moon, or the recession of the Moon from the Earth. ... Why the Moon's rotation period is the same as the length of time it takes to orbit the Earth (same as number 1, but phrased differently). ... But when this happens, the time it takes for the Earth to rotate once will be slowed to exactly the same time it takes for the Moon to go around the Earth once! ...

When calculating the motions of the oceans and the atmosphere, it is much easier to use reference points on the rotating Earth and add a centrifugal force to all equations. ... The rest arises because the Earth is not a perfect sphere: the centrifugal force of its rotation causes its equator to bulge out , making the surface there more distant from the Earth s center and thus weakening the gravitational pull. ...

... However to my eye the colour scheme that looks best is what might be described as a `thermal' one, ie one in which cool objects (objects with a long-wavelength excess) are coloured red and hot objects blue, with the intermediate sequence going from red through yellow and white to blue. ... The parameter heat shifts colours along the thermal sequence: at heat = -1 all colours go to red, at +1 they are all blue, with again 0 having no effect. ...

A full explanation of the motion of trapped particles would be too abstract and mathematical for this level, but some basic ideas may be described on an intuitive level. The magnetic force on a moving particle is always perpendicular to the motion, as well as to the magnetic field lines. That is why the basic pattern is motion in a circle, around a magnetic field line. ... The best-known periodic motion is the back-and-forth swing of a pendulum, say of a weight suspended by a string (drawing). ...
