Figure 1: Hand stencils have survived on the walls of caves for tens of thousands of years, storing information about who was there.
Figure 2: The electric dipoles in the ferroelectric layers (pale blue) of the nanocapacitors built by Lee et al. can point up or down, and can be switched by applying a voltage of the correct polarity to the upper electrode (left).
