Part VI: Atoms, Chemistry, and Molecular Structure

Part Overview

The complexity ladder ascends. Nuclei (Part V) combine with electrons to form atoms. Atoms bond to form molecules. Molecular structure, organic chemistry, biochemistry—all emerge from T² quantisation on the τ³ fibration.

In eleven chapters, we ascend from the hydrogen atom through the Bohr radius and Rydberg constant, through shell structure and bonding, through molecular geometry and organic chemistry, to the biochemistry that bridges to Book VI. Chemistry is not a separate science: it is τ² mode physics at molecular scale.
