Don't Write the Tedious Thing An Article by Maud Newton maudnewton.medium.com Ugh, now I have to write this boring part, I would think. I would spend a few days in active rebellion against this directive that I imagined the book was imposing. Then I would realize: this is my book! There are no rules! I can write it however I want! Also, I would think, if I’m bored by something that I believe I need to write, the reader undoubtedly will be too, if not because the subject is inherently boring, then because I myself find it so unbearably tedious to imagine discussing it for five pages. Often as not, I would remember some aspect of the subject that deeply interested me, something a little outside the way it’s usually perceived or written about. Then I would meditate on that, and soon I would be scribbling notes from an increasingly excited place until I found a way forward. A form of beginner’s mind.

Wang tiles Wang tiles (Hao Wang, 1961) are a class of formal systems. They are modelled visually by square tiles with a color on each side. A set of such tiles is selected, and copies of the tiles are arranged side by side with matching colors, without rotating or reflecting them. The basic question about a set of Wang tiles is whether it can tile the plane or not, i.e., whether an entire infinite plane can be filled this way. The next question is whether this can be done in a periodic pattern. In 1966, Wang's student Robert Berger solved the problem in the negative. He proved that no algorithm for the problem can exist, by showing how to translate any Turing machine into a set of Wang tiles that tiles the plane if and only if the Turing machine does not halt. The undecidability of the halting problem then implies the undecidability of Wang's tiling problem.
