(PhysOrg.com) -- 3D printing has been around for a few years. If you hooked it up to a solar panel you could make it work with the sun, but still would not be as cool as doing it the way that Markus Kayser, a MA student at ...
What do the convolutions of the brain, the emergence of wrinkles, the formation of mountain chains, and fingerprints have in common? All these structures, albeit very different, result from the same process: the compression ...
