We all know that nanotechnology and nanoscience deal with really, really, really small things, but how small is small, exactly? Let the Molecular Foundry, part of the Lawrence Berkeley National Laboratory in California, show you using a common penny.
In this YouTube video clip, the lab used beams of electrons to sketch letters that spell “Molecular Foundry” with the smallest feature roughly being 20 nanometers (about 100 atoms). As the video zooms out, you’ll see the Berkeley Lab logo written using a beam of charged gallium atoms. Then, as the video continues to zoom out, you’ll see an 18-hour timelapse of the face of Abe Lincoln, drawn with gallium atoms.

I only wish we could reverse the video clip, and yell out “Enhance” like in CSI.
