IBM researchers used a new nanopatterning technique to create the "world' smallest" 3D map of the Earth. Approximately 1000 of them would fit on a single grain of salt. Separately, they also carved out a 25-nanometer tall model of the Matterhorn. A nanometer, of course, is one-billionth of a meter, so that's a 1:5 billion scale nano-mountain.
From IBM Research:
The core component of the new technique, which was developed by a team of IBM scientists, is a tiny, very sharp silicon tip measuring 500 nanometers in length and only a few nanometers at its apex...
The tip, similar to the kind used in atomic force microscopes, is attached to a bendable cantilever that controllably scans the surface of the substrate material with the accuracy of one nanometer–a millionth of a millimeter. By applying heat and force, the nano-sized tip can remove substrate material based on predefined patterns, thus operating like a "nanomilling" machine with ultra-high precision.
This oft-seen wonderfully weird photo depicts Hugo Gernsback wearing his “teleyeglasses” in 1963. Gersnback, an inventor of such innovations as a combination electric hair brush/comb and a battery-powered handheld illuminated mirror, is best known to science fiction fans as the founder of Amazing Stories magazine! Gernsback coined the term “science fiction” and the Hugo Awards […]

If people want to change present circumstances through liberal ideals, it’s helpful to look […]
Steven “Hackers” Levy has a long view of Trump: as radical as he is, he’s only a drop in the bucket compared to the political and social changes wrought by technology: “Who was king during the industrial revolution in England? The quirks and flaws of government leaders are not relevant information when studying the enlightenment. […]
