This flight of steps runs up the outside of a Modernist house in Switzerland. What is striking here is the precise construction of relationships. The gaps between steps allow crisp lines of light to fall on the darkly shadowed wall, reinforcing the subtlety of the dialogue between granite and the concrete, which has been bush-hammers to expose the stone aggregates.
...There is something hypnotic about stair climbing, and as often as I find myself thinking I ought to be at the fourth floor when I am only at the third, I think I've only gotten to three when I'm actually arriving at four.
...To my eyes (and legs) the straight run is more elegant and enjoyable to ascend.
...The narrowing is both functional and artistic, acknowledging that a stair is likely to be used by a smaller number of people as it rises and forcing the perspective narrowing of the long view upward.
...The symbolic weight of stairs is embodied in both their form and their magnitude.
For two and a half months I did not see a stairway in America. They are something that has been buried...hidden behind a door that you are not supposed to open.
Many systems are organized hierarchically. The CERNDOC documentation system is an example, as is the Unix file system, and the VMS/HELP system. A tree has the practical advantage of giving every node a unique name. However, it does not allow the system to model the real world. For example, in a hierarchical HELP system such as VMS/HELP, one often gets to a lead on a tree such as:
HELP COMPILER SOURCE_FORMAT PRAGMAS DEFAULTS
only to find a reference to another leaf: Please see
HELP COMPILER COMMAND OPTIONS DEFAULTS PRAGMAS
and it is necessary to leave the system and re-enter it. What was needed was a link from one node to another, because in this case the information was not naturally organized into a tree.
