LOOK AGAIN…

Just for Fun!

See if you can find the 8 differences in each set of images.

Edge of the world

At one point, humans believed that the earth was flat and that an “edge of the world” existed, where the ocean fell off Into darkness. This ¡mage shows a fabricated film of carbon nanotube bundles and Its chaotic, ocean-like waves obtained via scanning electron microscopy (SEM) with nanoscale resolution. This uncoated SEM cross section shows a film of entangled single-walled carbon nanotubes falling off the edge of a glass substrate, fabricated for novel nanomaterials in blosensing and disease diagnostics. Image is taken on an FEI Magellan 400 XHR SEM at the University of California, Irvine.
