Look for

Is there a quantity that can move or change form but never appear or vanish — so if it seems to go missing, you've overlooked a path?

This is a reasoning lens, not ownership: the concepts belong to their disciplines, not to the model.

What am I looking at?

In this lens (10)

  • Chemical reaction14
    Atoms are conserved across a reaction; they are only recombined.
  • Carbon cycle10
    Carbon is neither created nor destroyed, only moved between reservoirs.
  • Water cycle9
    Water is conserved as it cycles between ocean, air and land.
  • Nitrogen cycle6
    Nitrogen is conserved as it is fixed, used and returned to the atmosphere.
  • Mass4
    In ordinary reactions mass is conserved — atoms are rearranged, not lost.

Concept collections

Concept collections are curated lenses onto the fabric — themed sets of ideas that recur across disciplines. They are not journeys; they are a way to read the graph.

About this view

What this is

Start from one concept and expand outward. The view never shows everything at once — click a node to refocus, filter by relationship type, or switch to an accessible list.

One fabric

3750 concepts and 5051 typed relations form one connected component — no isolated silo.

How to read it

Focus a concept, or apply a lens (discipline, mental model, journey) to see only the threads that matter.
