Bridges as walls The biographer of Robert Moses, Robert A. Caro, refers to the bridges and underpasses of the famed New York State parkways. These bridges and underpasses are quite low, intentionally specified by Moses to allow only private cars to pass. All those who traveled by bus because they were poor or black or both were barred from the use and enjoyment of the parkland and its "public amenities" by the technical design of the bridges. Even at the time of Robert Moses, a political statement of the form "We don't want them blacks in our parks" would have been unacceptable in New York State. But a technological expression of the same prejudice appeared to be all right. Of course, to the public the intent of the design became evident only after it was executed, and then the bridges were there. Ursula M.

Apologia A Chapter from A Search for Structure by Cyril Stanley Smith If the features of many are comparedPebbles on the beachHalf-formed perceptionInterdisciplinary
If the features of many are compared Almost all fields today are concerned in one way or another with hierarchical structure, and a theory, or perhaps more usefully a metaphor, common to all may emerge if the features of many are compared. Though the units in different fields are different, in all of them meaning comes through communication: patterns of communication are common to all, with aggregation leading to diversity or unity, and the clumps of unity themselves serving in turn as units in larger structrures based on more complex but still direct communication. hierarchystructure
Pebbles on the beach Newton picked up the pebbles on his metaphoric beach with an intellectual objective in mind, but his ancestor in paleolithic times picked up real minerals because he enjoyed looking at them: quite inadvertently he started the chain of practice and craftsmanship and thought that led to the diversity of specialized materials and generalized theory today. More like the early Homo sapiens than the sixteenth-century intellectual giant I have enjoyed a life of rather undisciplined wandering and search. searchcuriosity
Half-formed perception Science must be simple, yet the human brain has a structure that gives it the capacity for relating to the world in its undivided complexity in ways that are not logical, though they are effective. Aesthetic interest aroused by observation and half-formed perception seems usually, perhaps always, to precede exact analysis. intuitioncognition
Interdisciplinary These papers are probably to be called interdisciplinary—an “in” word these days—but any value they may have derives from the fact that the author started with a rather deep immersion in a single discipline. One cannot hope to understand the nature of interaction between impinging areas without a firm knowledge of at least one of them. knowledgescience
