I still remember being a child and my Grandad telling me that black was the absence of all light. It was an astonishing thought as I couldn’t fathom how it could be absence if I could see it.
A new material developed by Surrey NanoSystems reminded me of this.
Watch the video and be astonished when the sample is turned over to show the backing and then turned back to show the black front face again. It’s nice to have a dash of childlike wonder on a Monday afternoon.
