International Year of Crystallography 2013
In 1912 Max von Laue showed that X-rays were diffracted by crystals, and in 1913 W. H. and W. L. Bragg demonstrated that the diffraction of X-rays can be used to determine the positions of atoms within a crystal.
These groundbreaking experiments mark the birth of modern crystallography. The International Union of Crystallography (IUCr) is marking the centennial of these events by declaring 2013 the International Year of Crystallography (IYCr2013).
