14 DAY TRIAL // Every once in a while, scientists decide to do something just for the fun of it, and ordinary folks couldn't be happier whenever this happens.
LiveScience reports that, not long ago, a team of Georgia Tech researchers succeeded in creating a copy of the Mona Lisa that measures merely 30 microns in width.
To put things into perspective, it must be said that the average human hair has a width of about 90 microns. So yes, this is one really tiny Mona Lisa.
The same source informs us that the miniature reproduction of the famous painting was created with the help of an atomic force microscope and a technique dubbed ThermoChemical NanoLithography.
Thus, heat was applied on each and every pixel that makes up the image. The higher the temperature a pixel was exposed to, the lighter the shade of gray that was obtained.
By contrast, pixels exposed to relatively low temperatures remained black.
