Relative to the rapid pace set in the X-ray and visible light regimes, developing electron ptychography into a useful, routine method for electrons has so far been a slow journey. The path has been hampered by hurdles such as inelastic and dynamical scattering, instrument instabilities and limited beam coherence, as well as by the sub-nanometer resolutions that electron microscopists expect. Today, however, the route is being cleared using advances from the X-ray and visible light regions of the spectrum, and momentum is beginning to build.
