A layered, computable map of reality — mathematics → physics → chemistry → biology.

What am I looking at?

Each point is a concept; each line is a dependency — what that concept rests on. The corpus spans four epistemic layers and roughly 2,590 concepts joined by about 3,949 typed edges. Search a term or click a node to light up its neighbours and trace how ideas connect across fields.

Everything here can be calculated

This isn’t a static encyclopedia. Every operational concept carries an attached compute handler that returns its actual value or formula — derived, not looked up. Fundamental constants come from CODATA-2022, every numeric result is checked for SI-dimensional consistency, and each carries provenance back to the defining literature. More than 900 concepts are executable this way, from π to a Rankine–Hugoniot shock jump. The map shows the structure; a real engine stands behind it that evaluates the pieces numerically.

The four layers

L0 Mathematics · L1 Physics · L2 Chemistry · L3 Biology. They are ordered by certainty: a chemistry result may depend on physics, which depends on math — and the model will not let a higher layer claim more confidence than the foundations it rests on.

How to explore

Type a concept and press Enter. Click any node to highlight its connections, or pick a search result to focus its neighbourhood. Public browsing allows 10 searches per day.
