Jan 21st, 2017: Crack
Grand Canyon? Nope, too narrow.
Another counties canyon? Nope. Maybe a crack on Mars? Nope. http://cellar.org/2017/microcrack.jpg It's a teeny tiny micro-crack in a piece of steel viewed through an electron microscope. Beest can explain, this is his forte. :D |
That was dirty pool putting that blue sky background up there.

My first thought was SEM image, but I would've guessed some kind of mineral, not metal. Makes me wonder what the false-color separation is based on, since it's my understanding that SEM images come back black and white. For instance:
https://timedotcom.files.wordpress.c...lity=85&w=1100 Meet the Ebola virus in what is probably the first SEM image to identify it. Most renditions of this image are false-colored, with the virus appearing yellowish on a light-purple background. 'Scanning electron microscopy' is a keyword string that can rabbit-hole an entire afternoon! |
I creeped myself out anticipating that the answer was a close-up view of human skin... Sorry - gross!
|
Yet another bunch of photos I need to retrieve from the archives, a friend of mine was a metallurgist for GE and she made a bunch of electron microscope images of a broken Campagnolo crank arm at different magnifications.
I will look. |
from a closed bridge over the Delaware?

Such cracks are a source of eddy current variations.

Yes, SEM images are intrinsically monochrome, that picture has been specifically taken at that angle and colorized for that effect. Other angles would provide better technical information.
We have a gallery of pretty pictures that cycles on a 60" TV above our SEM for visitors to gawp at. There is one I have been meaning to colorize as it looks like a meatball. |
BigV would that be the same as "Magnafluxing"?
