IBM researchers have produced a breakthrough technique that allows scientists to create nanoscale objects. The first mission was to produce the smallest 3D map of the world ever. Using a heated nanoscale silicon tip researchers carved a 22-by-11 micrometer 3D model of the world. At this size, 1000 world maps could fit on a grain of salt. One thousand meters of altitude correspond to roughly eight nanometers (nm).
