3 is important in decision making because it makes it easier to form a consensus. If I disagree with your idea, you have another entity to act as an arbiter.
The interesting part is solving the "closest pair problem" which is a part of the clustering algorithm. Hurts my head just thinking about it, god knows how someone came up with a solution like this.

Curiously, the turning effect we observe is not coming from stars moving in an orbit around the centre of the galaxy. When we plot the movement of the light coming from the spiral arms (or bar) of a galaxy, given their size and speed of movement it would require the stars to be moving faster than the speed of light. Also if the spiral arms were made up of orbiting stars, the ones closer to the center would move faster than the outer stars causing a winding effect, which we do no observe.
One theory suggests that we are observing a density wave sweep through material, which causes compression and heat, increasing the likelihood of new stars to be born, these stars burn bright and white. As this wave passes through, it leaves behind those stars in its wake, which over time burn less brightly than before.
One analogy that comes to mind an electronic circuit, although electricity travels at the speed of light, the actually charge carriers are moving relatively slowly, know as the drift velocity.
I was just going to say: all 33-1/3 rpm records - regardless of their thickness or chemistry - are observed to rotate at about the same rate, regardless of record size.
And (I'll note that) the drive belts are usually hidden from view.
what a fantastic resource! Just a thought...why did you start your bottom up approach at the operating system level. Surely, if we are being purist's we should start with mathematical constructs first. After all, computational machines existed in the minds of mathematicians long before the any machine was built.
