Atlas / Toolkit
Toolkit
Some fields become tools for everyone else. This page ranks fields by how far their ideas travelled in the atlas: directly into other threads, where a new field grew from them, and into other domains, where their results were put to use. The count of fields downstream includes indirect descendants too. It is a rough proxy for influence, built only from the lineage and crossings recorded on each field's page, and it undercounts anything the atlas has not yet surveyed.
