There Is No Word A Poem by Tony Hoagland www.poetryfoundation.org what I already am thinking about is my gratitude for language— how it will stretch just so much and no farther; how there are some holes it will not cover up; how it will move, if not inside, then around the circumference of almost anything— how, over the years, it has given me back all the hours and days, all the plodding love and faith, all the misunderstandings and secrets I have willingly poured into it. languagewords
Paths, edges, districts, nodes, landmarks The contents of the city's images which are referable to physical forms can conveniently be classified into five types of elements: paths, edges, districts, nodes, and landmarks. Paths are the channels along which the observer customarily, occasionally, or potentially moved. Edges are the linear elements not used or considered as paths by the observer. They are the boundaries. Districts are the medium-to-large sections of the city, conceived of as having two-dimensional extent. Nodes are points, the strategic spots in a city into which an observer can enter, and which are the intensive foci to and from which they are traveling. Landmarks are another type of point-reference, but in this case the observer does not enter within them, they are external. They are usually a rather simply defined physical object: building, sign, store, or mountain. Kevin Lynch, The Image of the City City districtsAs a kind of gateway cities
