Strength from both mass and form
Warmed by the afternoon sun
Textbooks on water-system engineering state that supply mains are generally installed on the north side of the street in the Northern Hemisphere and on the south side in the Southern Hemisphere, so that the sun will warm them. In both hemispheres they are supposed to be on the east side of north-south streets, on the premise that the afternoon sun is warmer than the morning sun.
An emblem of friendship
Bridges make connections; they bring people together—a role that has made them a traditional emblem of friendship. Consider the town of Mostar in Bosnia-Herzegovina. When fighting between ethnic factions broke out there in the 1990s, nothing symbolized the social disintegration more clearly than the destruction of a sixteenth-century stone-arch bridge that had linked the two parts of the town on opposite banks of the Neretva River. And the emblem of efforts to heal the divisions is a rebuilt bridge, opened with fireworks and fanfare in July of 2004.
Routine design
When we think of bridges, it is the dramatic and monumental long spans that come to mind first, especially the lithe suspension bridges such as the Golden Gate and the pure geometric arches such as Sydney Harbour. But the majority of bridges are not such spectacular structures. Most of them are ordinary overpasses, with spans of 30 or 40 feet, carrying roadways or rails across other thoroughfares or over small streams. You see such bridges by the dozen on any drive down the Interstate. They may be lacking in glamour, but they are more representative of a bridge builder's art.
The engineering and construction of girder bridges are pretty routine these days, but the bridges are not quite standard items you order from a catalogue. The girders, whether of steel or concrete, are custom-build for each bridge, then trucked to the site and hoisted into place with a crane. The designer still has scope for variation and creativity, and it shows out on the highways: some overpasses are prettier than others.
The Art of Doing Science and Engineering: Learning to Learn
A Book by Richard HammingThe Art of Doing Science and Engineering is the full expression of what "You and Your Research" outlined. It's a book about thinking; more specifically, a style of thinking by which great ideas are conceived.

“Design” is now “Product”
An Article by Dorian TaylorDesign has very little to do with what tools or methodologies you use, or what your job title is, or what you have a degree in, or even anything like “creativity”; design is about your relationship to constraints. Rather: to what extent are you defining constraints rather than just obeying them? Design is about taking a universe of possibilities and converging onto exactly one outcome. Being handed a set of constraints which you treat like immutable laws of physics (because many of them are) and solving within that envelope is what engineering is. To wit: what most designers are doing most of the time is actually a form of engineering, and engineers are always doing at least some design.
This is because genuine design—the power to define constraints—is a privileged political position within an organization, and not everybody can occupy it. In other words, the “seat at the table” comes first. Design is Steve Jobs infamously dropping an iPod prototype into his fish tank, pointing at the bubbles coming out and yelling at his staff to make it thinner. It doesn’t matter what your title is; Jobs is the designer in that scenario.
Are We Really Engineers?
An Essay by Hillel WayneInnovation in Structural Art
A Book by Eladio DiesteDieste's unique and innovative method of design, a melding of architecture and engineering, elevated these often humble buildings to masterworks of art.
Design Thinking
Ducks and decorated sheds
A duck is a building whose confirmation is a complete symbol or icon. A decorated shed is a building to which symbols, often commonplace signs, have been attached.
Clinging to ideas
Another aspect of design thinking that was evident in the foregoing case studies is the tenacity with which designers will cling to major design ideas and themes in the face of what at times might seem insurmountable odds. Often the concept the designer has in mind can only come to fruition if a large number of apparently countervailing conditions can be surmounted.
Even when severe problems are encountered, a considerable effort is made to make the initial idea work, rather than to stand back and adopt a fresh point of departure.
A concept of style
It is a concept based not on the classification of various physical features of architecture and urban design but on the problem-solving process itself. We have seen that the final outcome of a design process is strongly determined by at least three aspects of that process:
- the subject matter of the organizing principles which are adopted,
- the manner in which these principles are interpreted and reinterpreted in the context of the problem at hand, and
- the sequent of applying such organizing principles.
Consistency in style among the output of designers can thus be understood as a habitual way of doing things, of solving problems.
Form and figure
Form applies to “a configuration with natural meaning or none at all,” whereas figure applies to “a configuration whose meaning is given by culture."
Design skirmishes
it is apparent that the unfolding of the design process assumed a distinctly episodic structure, which we might characterize as a series of related skirmishes with various aspects of the problem at hand.
As the scope of the problem became more determined and finite for the designer, the episodic character of the process seems to have become less pronounced. During this period a systematic working out of issues and conditions took hold within the framework that had been established. This phenomenon is not at all surprising when we consider the fundamental difference between moments of problem solving when matters are poorly defined and those with clarity and sufficiency of structure.
Within the episodic structure of the process, the problem, as perceived by the designer, tends to fluctuate from being rather nebulous to being more specific and well-defined. Furthermore, moments of "blinding" followed by periods of backtracking take place, where blinding refers to conditions in which obvious connections between various considerations of importance go unrecognized by a designer.
Such plans were deemed efficient
The terrain of cities was subdivided along the lines of distinct and discrete patterns of use, with very little opportunity for mixing (separation and concentration of functions). After all, the home environment should be just that…while places of work should be aggregated and serviced with their appropriate supporting functions.
Such plans were deemed efficient.
Constrained by the medium
The inevitable reciprocation that occurs between the act of drawing and the thinking associated with it. The hand moves, the mind becomes engaged, and vice versa. We might ask: How much does the medium of expression actually constrain a design process?
A medium has a way of constraining our choices, and this influence may not involve conscious choice at all. The planner, in the end, sees and understands only those things for which they can provide expression.
Autonomous constraints
Autonomous or independent constraints do not derive from the problem as given and understood…there was nothing in the problem statement, or brief, that required any reference be made to it. This constraint, introduced by the designers, usefully transcended the givens of the problem situation.
Unless the entire problem at hand can be solved using strictly problem-oriented constraints, we have to step outside the known problem context in order to continue problem solving activity.
The strange familiar and the familiar strange
The problem solver, when confronted with a new and yet unsolved problem, overlays the structure of the unsolved problem with an apparently similar problem with which he or she is experienced.
Making the strange familiar and the familiar strange are also principally based on the use of analogy.
