Very cool short video on surface flattness

Yes,  cool video thanks for posting it up vlaiv. Funny I was getting annoyed by his casual interchange of flatness and surface smoothness just at the point where he clarifies on the video.  Frustration abated     I would never have guessed that mica would have performed so well. I knew about its properties of cleaving but never associated the two - that was cool.  I wonder if the likes of graphene would have similar properties.

Very interesting, reminded me of a video about sharpness for surgeons cutting tools, stone age technology won out...

The Mica made the Gauge Block look like the Himalayas!
