# Incoprea Theory, Volume XIII — 62 theories, 31 subfields

Built 30 October 2026. **Entry page: `crypt.html`.** There is no `index.html`.

Sixty-two original theories, two in each of twenty-nine physical-science subfields the series had
not treated on its own. The earlier volumes leaned biological, earthly and social; this one is physics,
chemistry and the physical earth.
