What:

"A crystal is like a class of children arranged for drill, but standing at ease, so that while the class as a whole has regularity both in time and space, each individual child is a little fidgety! "

"In some sense then, the crystal is like a very large molecule, and its valence electrons occupy the molecular orbitals formed from the atomic orbitals of each atom "

What:

"Most of our understanding of science likes to reference common structures. Atomic structure is like the solar system, crystal structure is like tinker toys, and we love to anthropomorphise the mechanisms of pretty much everything in the body. Neurons are said to "talk." The brain's processes are described to resemble thinking. RNA is said to "read" sequences of amino acids encoding proteins. This article says that if we try to reduce a gene to something we already know, we may never understand its complexities."

What: "A crystal structure is like a three-dimensional wallpaper design in that it is an endless repetition of some motif (i.e., a group of atoms or molecules). The process of creating the motif involves point-group operations (rotation, reflection, and inversion) that define it. The process of creating the wallpaper involves translation (with or without rotation or reflection)to create the complete structure (which we call the lattice)."

"However, the crystal structure is like a frozen image of the enzyme and it does not show how it actually operates; in the same way it is difficult to see today how King Charles II was a successful womanizer from his formal portraits."
