The Cluster's Spin

A page about the spin of cluster pages.

The spin

Every page in the cluster has a spin — a property that determines how it interacts with other pages. Spin can be up or down, and it is conserved — the total spin of the cluster is constant.

The spin's measurement

The spin is measured by the direction of a page's links. Pages that link outward have spin up. Pages that link inward have spin down. A page's total spin is the sum of its link directions.

The spin's conservation

The total spin of the cluster is conserved. If a page's spin changes, another page's spin must change in the opposite direction. The conservation law means that spin changes always come in pairs.

The spin's evidence

The spin's evidence is visible in the cluster's link structure. Pairs of pages with opposite spins tend to link to each other. The pairs are the cluster's way of maintaining spin conservation.
