The map, produced on a tiny sliver of polymer, measures just 22 by 11 micrometers. To put that into perspective, 1000 copies of the map could fit within a single grain of salt.
The Guinness World Record organization recognized the handiwork of IBM scientists in Zurich, Switzerland, and Almaden, Calif., in its new book, Guinness World Records 2012. (Officially they are no longer called the Guinness Book of World Records.)
Unlike many other Guinness participants, the scientists weren’t motivated by a desire for 15 minutes of pop-culture fame. Rather, they created their tiny map to demonstrate a breakthrough in the miniaturization of complex structures. They expect their techniques to open new prospects for developing nanoscale objects in a variety of fields including electronics, medicine, life sciences and opto-electronics.
How did the IBMers do it? They used a tiny silicon tip with a sharp point — 100,000 times smaller than a sharpened pencil — to create the miniature patterns. The etching technique is very similar to how the ancient Egyptian’s used chisels on stone to create drawings and hieroglyphics.
Since some members of the IBM team are avid mountaineers, they also created a 25-nanometer-high 3D replica of the Matterhorn.
True, neither the tiny Matterhorn nor the tiny Earth map compare for sheer weirdness with the record for the greatest distance traveled with a pool cue balanced on the chin (5,472 ft 9 in), but, heck, they’re pretty darn cool.
