If you think of the length of the day at any point on Earth as a sine curve, the solstices are the maxima and minima. It is not the distance between the Earth and the sun that is the primary source of seasonal changes, rather it is the degree to which the axial tilt of the planet exposes a particular region to greater or lesser illumination at a certain time.<BR/><BR/>This is naturally most extreme at the poles and least extreme in the tropics.<BR/><BR/>The solstices are also the points at which the Earth's axis is pointed most and least towards the sun.<BR/><BR/>---<BR/><BR/><A HREF="http://www.sindark.com/2007/01/22/time-and-our-imperfect-orbit/" REL="nofollow" TITLE="a sibilant intake of breath » Blog Archive » Time, and our imperfect orbit">More on time and our orbit</A>Milanhttps://www.blogger.com/profile/15677497972102221231noreply@blogger.comtag:blogger.com,1999:blog-15726646.post-76743732905801452552008-06-29T19:04:00.000-04:002008-06-29T19:04:00.000-04:00It was nice meeting you David.

Perhaps we should arrange another gathering of bloggers at the point of inflexion of the sine curve (ie, when the second derivative is 0), you know first day of autumn (or spring). That's correct, right Milan?skylarkhttps://www.blogger.com/profile/01817337555824824466noreply@blogger.com
