While going through my daily reading list, one particular image posted on the Tumblr blog Daily Overview, which publishes high quality satellite photos of interesting places, grabbed my attention. At first I thought it was an integrated circuit, until I read the description, which said:
Colorful, metal-roofed industrial buildings line the coast of Tokai, Japan. The city’s economy is dominated by a massive steel mill - a portion of which is seen at the bottom of this Overview.
I was struck by how similar the satellite image looked to a close-up photo of an integrated circuit. You can check this out in the comparison published below. The image on the left is taken from the satellite and the image on the right is that of Intel’s Pentium 4 processor. The colors seen in the photograph of the processor are the actual colors produced by the diffraction/refraction of the light illuminating the die.
A similar discovery was made by Stephen Young and Paul Kelly, both science professors at Salem State University. Young is a geography professor studying vegetation change on Earth using satellite imagery, and Kelly is a herpetologist who studies snakes’ scales under a microscope to determine which species are closely related evolutionarily.
A few years ago, Dr. Young noticed some of the electron microscopic images Kelly created and thought that a few of them looked like landscapes. As a joke, he took one of his own landscape image of dunes in the Sahara and put them on Kelly’s door tricking him into believing that it was an electron microscopic image. This got the two talking and comparing imagery.
“We found that we had this similar interest in understanding scale and how people perceive it,” Young said to Smithsonian Magazine.
The two scientists have since been collecting puzzling images that are difficult to tell apart.
"Some patterns appear to repeat themselves in nature," explained Dr. Young to Huffington Post. "The study of fractals has shown this for some patterns, where, as you zoom in, the same pattern repeats itself. Also, there is nothing in the image to provide you with a measure of scale and so it is all shape and pattern. Shape and pattern do not define size."
