Crystallography-- is the experimental science of determining the arrangement of atoms in the crystalline solids (see crystal structure). The word "crystallography" derives from the Greek words crystallon "cold drop, frozen drop", with its meaning extending to all solids with some degree of transparency, and grapho "I write". In July 2012, the United Nations recognised the importance of the science of crystallography by proclaiming that 2014 would be the International Year of Crystallography.
A photograph of about 500 atoms of Niobium (41) and Selenium (34) neatly arranged at the surface of a crystal (darker atoms are simply lying lower in the surface). The image was taken using a special kind of microscope (called a scanning tunneling microscope) by Professor Nai-Chang Yeh of Cal Tech's Condensed Matter Physics Group. Despite what you may have previously thought, it IS possible to "see" atoms
