Design means something even broader now. Sometime around World War II, it came to mean making things that “solve problems.” With the influence of mid-century global social movements and the rise of digital technology, it began to mean making things that are “human-centered.” And as of recently, design doesn’t have to involve making things at all. It can just mean a way of thinking.
Of all these developments, the idea of design as a broadly applicable way of thinking—the idea of “design thinking”—may end up being the most influential…At Stanford’s d.school, as cofounder Robert Sutton has said, “design thinking” is often treated “more like a religion than a set of practices for sparking creativity.”
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.
