| Crystal lattices consist of repeating units of a molecule, ion, or atom arranged in a symmetrical array. |
| There are only fourteen distinct types of Bravais lattices, and these are associated with seven crystal systems. |
| In Undecidable theories Tarski showed that group theory, lattices, abstract projective geometry, closure algebras and others mathematical systems are undecidable. |
| Because water molecules can bond only at certain angles, these lattices are full of empty space, and the solid takes up more room than the liquid. |
| Using nails or screws, connect the sides of the archways with wood or wire lattices from which the vines will grow. |
| Ultimately, confining logical molecules in layers or three-dimensional lattices of nanoscopic bubbles might allow a true molecular computer to be built. |
