Fascinating dust
« on: January 07, 2013, 09:28:59 PM »
In ScienceBits there's a an interesting description of what appeared to be ferrous and cement dust dendrites from kitchen renovation work depositing and forming into patterns on magnetic objects and on nylon fabric on the walls: Dust Dendrites

I wondered whether the patterns that formed on the nylon might have been due to static electrical charge. I recall that they use/used static charged objects to collect dust to help maintain "dust-free" environments in aircraft component manufacturing.

TIL: Our definitions of "Fascinating" differ vastly.  ;D

Rather random, but after typing my comment here, I hit next on Imgur, and found this: http://imgur.com/gallery/1a3H2

@Stephen66515: What a superb picture. From an electron microscope, presumably.(?)

This image taken by a black and white security camera, then enhanced by advanced CSI technology. For real!

On seeing the thread title, my first thought was of Philip Pullman's His Dark Materials trilogy  :)

Ah, thanks! I couldn't see that, because NoScript had blocked the comments. When I temporarily enabled them, I could see it.
I figured that the coulours were probably digitally enhanced, but I didn't know you could get that sort of quality out of microscope lenses. I want one.

^ I've no idea myself.
It does say magnified 22 million times, which (is that possible - I dont think something can be magnified that much!?!) makes me think electron, but I know nothing about this kind of technology.
