"You would need just the area postage stamp to write out all books ever written," said senior author Sander Otte, physicist at Delft University Technology's Kavli Institute Nanoscience in Netherlands. In fact, researchers estimated if they created cube 100 microns wide — about same diameter as average human hair made sheets atomic memory separated from one another 5 nanometers, or billionths meter, could easily contents entire U.S. Library Congress.
