Fifty-two hertz
In his story, Faiz repairs air conditioning all over Muscat on his own. He can diagnose a fault just by ear: "the compressor's vibrating at fifty-two hertz, it should be at fifty; in two weeks it'll stop," and two weeks later the client calls him. When an apprentice asked why the filters get cleaned every month, he answered flatly: "because the dust here isn't dust, it's sand, and sand doesn't forgive."
