Thanks and I do generally agree with your sentiment.

I read through the wikipedia but it didn't really click with me and I felt it definitely wasn't written for a five year old :-)

In my defence I wanted to hear how others would state the problem and was afraid of biasing the response by leading too much with what I may or may not correctly know. Though I had tried to provide some direction with my questions that I hoped would be addressed by others.

I thought the question was in line with the general HN guidelines of "anything that gratifies one's intellectual curiosity".
