		<description>An area that often intimidates at first blush, but becomes easily transparent upon being given a &quot;plain English translation&quot; is heuristics.  Once the purview of esoteric philosophy and the occasional bored mathematician, the &quot;problem solving&quot; nature of heuristic algorythms can be used to explain not just how the brain might work, but also open the door to true A.I.</description>

		<description>If it were possible to make it to the edge of the universe, why couldn&#039;t we go outside of the universe?  I was trying to explain to my students but I&#039;m not sure I even understand it.</description>

		<description>I&#039;ve always wanted to know the science behind harmonics (musically speaking, of course), especially how there can be one point 2/3rds of the way up a vibrating string that stays stationary; and why that proportion stays the same if you lengthen or shorten it.</description>

		<description>The speed of light is the same from all inertial frames of reference.

That would suggest that if I am traveling in a space ship at the speed of light (c) and I flip on my headlights, I could theoretically measure the light leaving my ship as c.  An observer on the ground would measure the speed of both my ship AND my headlights as c.

This is a tough concept for the mind to grasp (c + c = c, therefore c = 0, huh?).  Can you make this make sense?

While you are at it, is light a wave or a particle?  It has properties of both (frequency, responds to gravity, etc.).</description>

		<description>I completely agree with Becky! 
How about clarifying Lacan&#039;s work too?</description>
