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. https://w3id.org/delphi/resource/claim/bragg1915-03 http://www.w3.org/2000/01/rdf-schema#label In diamond each carbon atom is surrounded tetrahedrally by four others on two interpenetrating face-centred lattices https://w3id.org/delphi/resource/claim/bragg1915-03 http://www.w3.org/2004/02/skos/core#notation \text{CN}(\text{C}) = 4,\ \angle = 109.47^\circ https://w3id.org/delphi/resource/claim/bragg1915-03 http://www.w3.org/2004/02/skos/core#related https://w3id.org/delphi/resource/claim/thompson1917-ch09-10 https://w3id.org/delphi/resource/claim/bragg1915-03 https://w3id.org/delphi/ontology/context Bragg WH et al., “X Rays and Crystal Structure”, G.
