IBM scientists succeeded in forming stable rows of ten molecules along steps just one atom high on a copper surface. These steps act as rails, similar to the earliest form of the abacus, which had grooves instead of rods to keep the beads in line. Individual molecules were then approached by the STM tip and pushed back and forth in a precisely controlled way to count from 0 to 10 (see image).
