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).
*Logo design competition*
Entries are invited for the design of a logo for the International Year
The logo should symbolize and represent the fundamental importance of
crystallography to society.
The logo will be used for announcements, letterheads, brochures,
publications, web sites and other purposes as may be decided by the IUCr.
Designs should be sent by email to the IUCr Executive Secretary
(firstname.lastname@example.org) by *1 July 2011*.
