Devoid of ambition Miscellaneous handicrafts are devoid of ambition. Their purpose is to serve the needs of the people, not to achieve renown. Just as construction workers who have built a wonderful highway don’t sign their work, neither do artisans append their names to their ware. From beginning to end, without exception, such handicrafts are made by nameless craftsmen. It is this lack of desire for personal recognition that produces their flawless beauty.

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.
