On: How a razor blade can be damaged as it cuts human ...

That video was oddly pleasant to watch. I admit I was expecting to see the blade become miraculously f'd up in the process, due to the rest of the article, but hair is indeed very soft and the look of that angular cut at such a scale is kind of amazing to think about.

(Perhaps when such microscopes hit Aliexpress we'll see this genre enter the extremely-satisfying-videos arena)

It took a moment to realise it but given the scanning nature of the microscope this was actually done like a stop motion animation…

That or scanning electron microscopes have gotten a way faster “shutter speed” since I last looked at them.

Looks like we're seeing basically a recording of what you'd see at the microscope, just not in real time. The video is way sped up.
