<http://www.w3.org/2000/01/rdf-schema#comment> "Related claim <https://w3id.org/delphi/resource/claim/thompson1917-ch09-10> (same-quantity): The tetrahedral angle, arccos(-1/3) = 109.47°, appears in both: in diamond as the C-C-C bond angle measured here from the refined structure, in Thompson as the angle between the rays of a four-rayed spicule formed at the junction of four equal cells. In the crystal it is a fact of the lattice; in the spicule it is a claim about cell packing that has not been tested on specimens.";
