Since their discovery by Wilhelm Conard Röntgen, X rays have played a significant role in our lives: they make the unseen in our bodies visible; they enhance our security in air travel; they make possible nondestructive testing of a wide variety of materials. And through x‐ray diffraction and spectroscopy they make it possible to probe the order of matter at the atomic level.
