In Praise of Small Menus An Article by Rachel Sugar www.grubstreet.com The best way to experience a restaurant, I have always felt, is by eating exactly what it wants to feed you. I do not want choices. I want the best thing. A restaurant might have five or ten best things, but it cannot have 45. There are many infuriating things about the world, but one of the more fixable is the sensation of acute regret from having ordered wrong. Why are there possibly wrong orders? Recently, I was at a fancy restaurant with great pastas and bad pizzas. So cut the pizzas! A kitchen that focuses on its strengths turns out consistently excellent things, even if that results in fewer total things. fooduxchoicesimplicity
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.
