The thing that blows me away is the idea that nobody knows how to make a pencil. Essentially no one on Earth knows how to make a regular ol' number 2 pencil in it's entirety, from scratch with no materials to a finished product. I saw it in a TED Talk over 9 years, but I don't remember which one. I googled a bit and found a Wikipedia page on a book I'd never heard about called I, Pencil. [1] That's probably source material for the video I watched, which may be the TED talk referenced in the the external link section. [1] https://en.m.wikipedia.org/wiki/I,_Pencil |
