Freedomless freedom The beauty of kasuri is received as a gift. As long as the laws of nature are upheld, the beauty of kasuri remains intact. This demonstrates the curious principle that the artisan is deprived of technical freedom but works in the freedom of nature. In this sense, kasuri can be said to be created in a state of freedomless freedom. Yanagi Sōetsu, The Beauty of Kasuri freedomconstraintsnaturemaking
Technological middle age In the automobile's technological middle age, it is hard, if not impossible, to tune or repair one's own vehicle. Technical standardization of cars has occurred, and with it the elimination of the user's access to the machine itself. At the same time, the infrastructures that once served those who did not use automobiles atrophied and vanished. Some may say they were deliberately starved out. Railways gave way to more and more roadways. And thus a technology that had been perceived to liberate its users began to enslave them. Ursula M. Franklin, The Real World of Technology technologyfreedominfrastructure
Why We Build the Wall A Song by Anaïs Mitchell genius.com What do we have that they should want? We have a wall to work upon We have work and they have none And our work is never done And the war is never won The enemy is poverty And the wall keeps out the enemy And we build the wall to keep us free That’s why we build the wall We build the wall to keep us free So that its destruction cannot begin workfreedomcapitalism
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.
