To a Materials Engineer this video is more humorous then educational. Yeah I agree with Zane on that one. To a Materials Engineer this video is more humorous then educational.

Carbon adds nothing to corrosion resistance, it's all about the oxide phase you form on the surface. The formations you see as the microscope zooms in are not dendrites, they're a fracture surface. And the feature that they zoom into might or might not be pearlite, there's not way to know without either etching the surface with acid or jacking the contrast up so high in the microscope that you can see the difference in atomic weight of the two phases. Sorry to rain on everyone's parade, but I'm a Metallurgist, this is what I do for a living...

My frist thought was "are they blurry because of the electron cloud or the limit of the microscope?" You know, I’ve never seen an atom before that wasn’t an animation.
