Imperfect Crystals
Although the perfect lattice is an extremely useful model, real crystals always exhibit imperfections, which can have profound effects on the structure and properties of the material. André Guinier proposed a widely employed distinction between imperfections that preserve the long-range order of the crystal (disorder of the first kind) and those that destroy it (disorder of the second kind).

Famous quotes containing the words imperfect and/or crystals:
“We can glut ourselves with how-to-raise children information . . . strive to become more mature and aware but none of this will spare us from the . . . inevitability that some of the time we are going to fail our children. Because there is a big gap between knowing and doing. Because mature, aware people are imperfect too. Or because some current event in our life may so absorb or depress us that when our children need us we cannot come through.”
—Judith Viorst (20th century)
“It is clear that everybody interested in science must be interested in world 3 objects. A physical scientist, to start with, may be interested mainly in world 1 objects—say crystals and X-rays. But very soon he must realize how much depends on our interpretation of the facts, that is, on our theories, and so on world 3 objects. Similarly, a historian of science, or a philosopher interested in science must be largely a student of world 3 objects.”
—Karl Popper (1902–1994)
