		<description><![CDATA[Clocks ticks keep track of the natural passage of time in whatever frame they are in.  However, the starting point for counting those ticks may be arbitrary.  Unless clocks at different locations are synchronized, they are useful for only local activities. Clock setting in SRT is a critical but straightforward task in inertial frames.  Einstein [...]<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=ehrenfestparadox.wordpress.com&amp;blog=10767076&amp;post=53&amp;subd=ehrenfestparadox&amp;ref=&amp;feed=1" width="1" height="1" />]]></description>

Here&#8217;s a clock.- Think of an hourglass, then replace the top and bottom with facing mirrors, and the sand with a rather large, glowing, and improbably slow photon bouncing between the mirrors once every time unit. We have one, and others have identical clocks in other reference frames.

A basic function of SRT is to tell us the &#8216;where&#8217; and &#8216;when&#8217; of objects in one inertial reference frame as observed from a different inertial reference frame.  If we have a train speeding past [...]<img alt="" border="0" src="http://stats.wordpress.com/b.gif?host=ehrenfestparadox.wordpress.com&amp;blog=10767076&amp;post=17&amp;subd=ehrenfestparadox&amp;ref=&amp;feed=1" width="1" height="1" />]]></description>

		<description><![CDATA[The Ehrenfest Paradox is the single (arguably) remaining unresolved paradox in Einstein&#8217;s Special Relativity Theory. It proposes that relativistic Lorentz contraction around the circumference of a rotating disc or cylinder will alter the value of &#960;.
