The Nano Guitar: Discover the World’s Smallest, Playable Microscopic Guitar

In 1997, the Cornell Chronicle announced: “The world’s smallest guitar — carved out of crystalline silicon and no larger than a single cell — has been made at Cornell University to demonstrate a new technology that could have a variety of uses in fiber optics, displays, sensors and electronics.”

Invented by Dustin W. Carr, the so-called “nanoguitar” measured 10 micrometers long–roughly the size of your average red blood cell. And it had six strings, each “about 50 nanometers wide, the width of about 100 atoms.”

According to The Guardian, the vintage 1997 nanoguitar was actually never played. That honor went to a 2003 edition of the nanoguitar, whose strings were plucked by miniature lasers operated with an atomic force microscope, creating “a 40 megahertz signal that is 130,000 times higher than the sound of a full-scale guitar.” The human ear couldn’t hear something at that frequency, and that’s a problem not even a good amp–a Vox AC30, Fender Deluxe Reverb, etc.–could fix.

Thus concludes today’s adventure in nanotechnology.

All the Rivers & Streams in the U.S. Shown in Rainbow Colours: A Data Visualization to Behold

This is a sight for sore eyes. Created by Hungarian geographer and map-designer Robert Szucs, using open-source QGIS software, the high resolution map above shows:

all the permanent and temporary streams and rivers of the contiguous 48 states in beautiful rainbow colours, divided into catchment areas. It shows Strahler Stream Order Classification. The higher the stream order, the thicker the line.

When you look at the map, you’ll see, as The Washington Post observes, “Every river in a color drains to the same river, which then drains into the ocean. The giant basin in the middle of the country is the Mississippi River basin. Major rivers like the Ohio and the Missouri drain into the behemoth.” Pretty impressive.

The map was apparently made using data from the European Environment Agency and the Rivers Network System.

You can find the map on Imgur, or purchase “ultra high” resolution copies through Etsy for $8.

Szucs has als0 produced data visualizations of the river systems in China, India, Europe and other parts of the world.
