I love this pic from flickr. It is a scanning electron microscope image of Zinc Oxide (ZnO) nanostructures (that is, really small ZnO structures) on indium oxide coated glass.
I'm not sure if it is a chance photo, or one deliberately created, but either way it is cool!
Scanning electron microscopes create images by scanning a surface with a beam of high-energy electrons. The electrons interact with the atoms that make up the sample, and this interaction produces various signals from which a sample's surface topography can be recreated. The interactions between the electron beam and the sample can give off x-rays or light, it can also cause the electron beam to be scattered, and small currents can be generated in the sample. These signals can be read by sensitive equipment which can then reconstruct what the surface looks like.

I love science Day's.I once went to a science day and I saw a pyramid lightning a bulb wich was lit by the energy that the pyramid was absorbing from the thin air.I was a little shocked because I didn't understood exactly the process. راغب
