WebThe emergence of crystallography (study of crystals) as an independent science was directly related to the development of optical instruments. Once the angles between … In 1669 Nicolaus Steno studied many quartz crystals and found angles between adjacent prism faces, termed interfacial angles, to be 120ono matter how the crystals had formed. For example, Figures 11.2 to 11.5 show four varieties of quartz with nearly identical crystal shapes and similar angles between … See more In the previous chapter we discussed symmetry due to rotation, reflection, and inversion. These are all types of point symmetry. The orderly repetition of patterns due to … See more What possible shapes can unit cells have? Mineralogists begin answering this by considering only two dimensions. This is much like imagining what shapes we can use to tile a floor without leaving gaps between tiles. Figure … See more In the preceding sections, we discussed the shapes and symmetries of crystals. We now turn our attention briefly to space symmetry, the … See more In two dimensions, patterns are made of unit cells and lattices describe how unit cells and motifs repeat. These relationships are the same in three dimensions. Figure 11.33, for example, shows a single atom … See more
