Urban form and grain
One square mile of different cities' street networks, held at the same scale to compare the urban form and grain.
Names vs. The Nothing
This is the first site along the tour. In here we have a void. I remember the building that used to stand here, it was painted blue. Passing through it, you can imagine how us, as ghosts – should the building be standing here – would have to actually be invisible to pass through these walls and now it’s the reverse. The building is the ghost and we’re passing through these walls.
The linear city
The linear city was an urban plan for an elongated urban formation. The city would consist of a series of functionally specialized parallel sectors.
As the city expanded, additional sectors would be added to the end of each band, so that the city would become ever longer, without growing wider.
A dialogue between homogeneity and exception
All cities can be described as a dialogue between homogeneity and exception, and each strikes a particular balance that is at the core of its character.
Ground displaced upward
Imagine that our rooftops were parkland, that the area of ground occupied by buildings was, in effect, simply displaced upward. Imagine that the city enacted legislation requiring that the equivalent of 100 percent of the surface area of New York were to be green. A 100 percent requirement would not simply oblige green roofs. It would also demand that compensatory greenery be added to make up for such ungreenable areas as roadways, runways, and other unplantable places. Perhaps the requirement would be satisfied with road narrowings, cantilevered gardens, or green floors in buildings (utilities on the order of the mechanical floors that occur in almost all tall buildings).
Same name in the same basket
Does a concert hall ask to be next to an opera house? Can the two feed on one another? Will anybody ever visit them both, gluttonously, in a single evening, or even buy tickets from one after going to a performance in the other?
In Vienna, London, Paris, each of the performing arts has found its own place, because all are not mixed randomly. The only reason that these functions have all been brought together in Lincoln Center is that the concept of performing art links them to one another. The organization is born of the mania every simple-minded person has for putting things with the same name into the same basket.
A city cannot be a work of art
There is a basic esthetic limitation on what can be done with cities: A city cannot be a work of art.
The kind of problem a city is
Dr. Weaver lists three stages of development in the history of scientific thought: (1) ability to deal with problems of simplicity; (2) ability to deal with problems of disorganized complexity; and (3) ability to deal with problems of organized complexity.
The history of modern thought about cities is unfortunately very different from the history of modern thought about the life sciences. The theorists of conventional modern city planning have consistently mistaken cities as problems of simplicity and of disorganized complexity, and have tried to analyze and treat them thus.
These loose notes
These loose notes are one possible description of our city. A city that, as in Constantin Cavafy's poem The City, is and always will be the same, in the same city again.
Strands of life
For the human mind, the tree is the easiest vehicle for complex thoughts. But the city is not, cannot, and must not be a tree. The city is a receptacle for life. If the receptacle severs the overlap of the strands of life within it, because it is a tree, it will be like a bowl full of razor blades on edge, ready to cut up whatever is entrusted to it. In such a receptacle life will be cut to pieces. If we make cities which are trees, they will cut our life within to pieces.
Natural and artificial cities
I want to call those cities which have arisen more or less spontaneously over many, many years natural cities. And I shall call those cities and parts of cities which have been spontaneously created by designers and planners artificial cities. Siena, Liverpool, Kyoto, and Manhattan are examples of natural cities. Levittown, Chandigarh, and the British New Towns are examples of artificial cities.
It is more and more widely recognized today that there is some essential ingredient missing from artificial cities.
Tree, leaf, house, city
"Tree is leaf and leaf is tree – house is city and city is house. A city is not a city unless it is also a huge house – a house is a house only if it is also a tiny city."
— Aldo van Eyck
To become completely lost
To become completely lost is perhaps a rather rare experience for most people in the modern city. We are supported by the presence of others and by special way-finding devices: maps, street numbers, route signs, bus placards. But let the mishap of disorientation once occur, and the sense of anxiety and even terror that accompanies it reveals to us how closely it is linked to our sense of balance and well-being. The very word "lost" in our language means much more than simple geographical uncertainty; it carries overtones of utter disaster.
Junctions
The junction, or place of a break in transportation, has compelling importance for the city observer. Because decisions must be made at junctions, people heighten their attention at such place and perceive elements with more than normal clarity. This tendency was confirmed so repeatedly that elements located at junctions may automatically be assumed to derive special prominence from their location.
A certain plasticity
There are dangers in a highly specialized visible form; there is a need for a certain plasticity in the perceptual environment. If there is only one dominant path to a destination, a few sacred focal points, or an ironclad set of rigidly separated regions, then there is only one way to image the city without considerable strain. This one may suit neither the needs of all people, nor even the needs of one person as they vary from time to time. An unusual trip becomes awkward or dangerous; interpersonal relations may tend to compartmentalize themselves; the scene becomes monotonous or restrictive.
A metropolis for hydrocarbons
An oil refinery suggests the image of a metropolis for hydrocarbons, the pipe manifolds like expressways, the distillation towers like skyscrapers.
Roads to nowhere
Among real-estate developers, straight lines and right angles went out of fashion sometime in the middle of the twentieth century. If you look at a town or a residential neighborhood laid out since then, you are more likely to find sinuous, serpentine roads—whether or not the topography offers any excuse for such curves. Many of these roads go nowhere: they are loops that bring you back to where you started, or they are cul-de-sacs. Making it easy to find your way through the network of streets is obviously not a high priority. This is an interesting development in urban geography: having redesigned the city to accommodate the automobile, we now search for ways to discourage people from driving on the streets.
Dead cities
If you can understand a city, then that city is dead.
NYLA
"See, what I've always liked about Los Angeles is that it's one of the least restrictive towns in the world. You can pretty much live any way you want to here. And part of that is because the place has no tradition and no history in that sense. It doesn't have any image of itself, which is exactly its loss and gain. That's why it's such a great place to do art and to build your ideas about culture. In New York, it's like an echo chamber: its overwhelming sense of itself, of its past and its present and its mission, becomes utterly restricting."

An Article by Chris ArnadeOn my first day I literally walk across the city, to the extent it can be done…The next day I do another cross town walk, but in a different direction, filling in the blanks from the prior day’s walk.
Then, over the next week(s), I walk between 10 to 20 miles per day, picking and choosing from what I have seen before, highlighting what I like, what I want to know more about, refining the path, till by the end of my trip, I have a daily route that is roughly the same.
While that is certainly not the most efficient way to see a city, it is the most pleasant, insightful, and human. I don’t think you can know a place unless you walk it, because it isn’t about distance, but about content.

Tilted Arc
An Artwork by Richard SerraIn the 1980s, Serra found himself in the center of a public controversy over his piece titled Tilted Arc. While it was the government that approached him to create the work for downtown Manhattan’s Federal Plaza, the unveiling of the piece in 1981 was met with sharp criticism. The monumental sculpture was said to disrupt rush hour and the pedestrians who had to cut through the plaza daily. To the dismay of art lovers, the 120-foot-long, 12-foot-tall Tilted Arc was ultimately disassembled in 1989.
Working with Brian Eno on design principles for streets
- Think like a gardener, not an architect: design beginnings, not endings
- Unfinished = fertile
- Artists are to cities what worms are to soil.
- A city’s waste should be on public display.
- Make places that are easy for people to change and adapt (wood and plaster, as opposed to steel and concrete.)
- Places which accommodate the very young and the very old are loved by everybody else too.
- Low rent = high life
- Make places for people to look at each other, to show off to each other.
- Shared public space is the crucible of community.
- A really smart city is the one that harnesses the intelligence and creativity of its inhabitants.
Towers in the Village
An Essay by Alfred TwuSince tall buildings have been around, there have been many ways they’ve fit into cities: towers in downtown, towers in the park, and most recently, towers on a whole-block development. Let’s look at a 4th way, the Tower in the Village.
Unlike the others, the Tower in the Village does not aim to be the center of attention. Instead, the upper floors are hidden behind a low front that fits in with the rest of the block. It faces a village green instead of a busy road.
Why highrise infill? Growing cities have two choices: 1) Redevelop a lot of sites to medium density, or 2) Redevelop a small number of sites to very high density. Highrise infill requires less demolition and can get more homes built faster.
Clues for software design in how we sketch maps of cities
An Article by Matt WebbGiven there’s an explosion in software to accrete and organise knowledge, is the page model really the best approach?
Perhaps the building blocks shouldn’t be pages or blocks, but
neighbourhoods
roads
rooms and doors
landmarks.Or rather, as a knowledge base or wiki develops, it should - just like a real city - encourage its users to gravitate towards these different fundamental elements. A page that starts to function a little bit like a road should transform into a slick navigation element, available on all its linked pages. A page which is functioning like a landmark should start being visible from two hops away.

Psychogeography
A Definition by Guy DebordPsychogeography is an exploration of urban environments that emphasizes playfulness and "drifting". It was defined in 1955 by Guy Debord as:
- "The study of the precise laws and specific effects of the geographical environment, consciously organized or not, on the emotions and behavior of individuals."
- "A total dissolution of boundaries between art and life."
- "A whole toy box full of playful, inventive strategies for exploring cities...just about anything that takes pedestrians off their predictable paths and jolts them into a new awareness of the urban landscape."
Title Cities
An Artwork by Nicholas RougeuxA book’s title page contains more than its namesake—including its author, contributors, publisher, and release date, and. Antiquarian books are known for having lengthy titles, especially those of a scientific nature. These books’ frequently unassuming title pages are gateways to a wealth of knowledge and the focal point of this project.
Title pages of antique influential scientific books covering a variety of subjects were coded and reimagined as colorful cityscapes based solely on their words to illustrate the unique body of knowledge readers would find within.
Boxes were drawn around each word of a title page and color-coded by its first letter (words beginning with “A” are one color, “B” another, and so on). Each title page has its own palette. Those boxes were then upended and arranged to form an abstract cityscape while maintaining their original sizes relative to each other.

A Book by Nicholas de MonchauxLocal Code’s data-driven layout arranges drawings of 3,659 digitally tailored interventions for vacant public land in San Francisco, Los Angeles, New York City, and Venice, Italy. The natures of these found parcels is as particular as the cities that house them — land under billboards in Los Angeles, dead-end alleys in San Francisco, city-owned vacant lots in New York City, and abandoned islands in the Venetian lagoon — but have in common an unrecognized potential as a social and ecological resource.
Urban Street Network Orientation
An Article by Geoff BoeingThis study measures the entropy (or disordered-ness) of street bearings in each street network, along with each city’s typical street segment length, average circuity, average node degree, and the network’s proportions of four-way intersections and dead-ends. It also develops a new indicator of orientation-order that quantifies how a city’s street network follows the geometric ordering logic of a single grid. These indicators, taken in concert, reveal the extent and nuance of the grid.

The Art of Doing Science and Engineering: Learning to Learn
The 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.
Gifts of knowledge to humanity
There are many commonalities we can admire in these endeavors: the dazzling leap of imagination, the broad scope of applicability, the founding of a new paradigm. But let’s focus here on their form of distribution. These are all things that are taught. To “use” them means to learn them, understand them, internalize them, perform them with one’s own hands. They are free to any open mind.
In Hamming’s world, great achievements are gifts of knowledge to humanity.
Hamming-greatness
Hamming-greatness is tied, inseparably, with the conception of science and engineering as public service. This school of thought is not extinct today, but it is rare, and doing such work is not impossible, but fights a nearly overwhelming current.
It cannot be taught in words
How to be a great painter cannot be taught in words; one learns by trying many different approaches that seem to surround the subject. Art teachers usually let the advanced student paint, and then make suggestions on how they would have done it, or what might also be tried, more or less as the points arise in the student’s head—which is where the learning is supposed to occur!
Preparing for problems
I firmly believe in Pasteur’s remark, “Luck favors the prepared mind.” In this way I can illustrate how the individual’s preparation before encountering the problem can often lead to recognition, formulation, and solution.
Student's future, not teacher's past
Teachers should prepare the student for the student’s future, not for the teacher’s past.
If you know what you are doing
In science, if you know what you are doing, you should not be doing it.
In engineering, if you do not know what you are doing, you should not be doing it.The homogeneity of knowledge
The standard process of organizing knowledge by departments, and sub-departments, and further breaking it up into separate courses, tends to conceal the homogeneity of knowledge, and at the same time to omit much which falls between the courses.
Another goal of the course is to show the essential unity of all knowledge rather than the fragments which appear as the individual topics are taught. In your future anything and everything you know might be useful, but if you believe the problem is in one area you are not apt to use information that is relevant but which occurred in another course.
An information service society
Society is steadily moving from a material goods society to an information service society. At the time of the American Revolution, say 1780 or so, over 90% of the people were essentially farmers—now farmers are a very small percentage of workers.
What will the situation be in 2020? As a guess I would say less than 25% of the people in the civilian workforce will be handling things; the rest will be handling information in some form or other. In making a movie or a tv program you are making not so much a thing, though of course it does have a material form, as you are organizing information.
From hands to machines
It has rarely proved practical to produce exactly the same product by machines as we produced by hand. Mechanization requires you produce an equivalent product, not identically the same one.
A matter of choice and balance
More than ever before, engineering is a matter of choice and balance rather than just doing what can be done. And more and more it is the human factors which will determine good design—a topic which needs your serious attention at all times.
Central planning gives poor results
Central planning has been repeatedly shown to give poor results (consider the Russian experiment, for example, or our own bureaucracy). The persons on the spot usually have better knowledge than can those at the top and hence can often (not always) make better decisions if things are not micromanaged.
"Real programmers"
At the time the Symbolic Assembly Program (SAP) first appeared I would guess about 1% of the older programmers were interested in it—using SAP was “sissy stuff,” and a real programmer would not stoop to wasting machine capacity to do the assembly.
Using your own expertise
Almost all professionals are slow to use their own expertise for their own work. The situation is nicely summarized by the old saying, “The shoemaker’s children go without shoes.”
History tends to be charitable
History tends to be charitable. It gives credit for understanding what something means when we first do it. But there is a wise saying, “Almost everyone who opens up a new field does not really understand it the way the followers do.”
The reason this happens so often is the creators have to fight through so many dark difficulties, and wade through so much misunderstanding and confusion, they cannot see the light as others can, now the door is open and the path made easy.
Mass production of variable products
Computers have opened the door much more generally to the mass production of a variable product, regardless of what it is: numbers, words, word processing, making furniture, weaving, or what have you. They enable us to deal with variety without excessive standardization, and hence we can evolve more rapidly to a desired future!
Thinking is a matter of degree
Perhaps “thinking” is not a yes/no thing, but maybe it is a matter of degree.
Making coal miners into programmers
Many humans at present are not equipped to compete with machines—they are unable to do much more than routine jobs. There is a widespread belief (hope?) that humans can compete, once they are given proper training. However, I have long publicly doubted you could take many coal miners and make them into useful programmers.
A minimum size to fish
There is the famous story by Eddington about some people who went fishing in the sea with a net. Upon examining the size of the fish they had caught, they decided there was a minimum size to the fish in the sea! Their conclusion arose from the tool used and not from reality.
Spelled with a lowercase letter
I used to tease John Tukey that you are famous only when your name was spelled with a lowercase letter such as watt, ampere, volt, fourier (sometimes), and such.
Why it can't be done
Moral: when you know something cannot be done, also remember the essential reason why, so later, when the circumstances have changed, you will not say, “It can’t be done.”
When you decide something is not possible, don’t say at a later date it is still impossible without first reviewing all the details of why you originally were right in saying it couldn’t be done.
Intellectual shelf life
Let lab equipment lie idle for some time, and suddenly it will not work properly! This is called “shelf life,” but it is sometimes the shelf life of the skills in using it rather than the shelf life of the equipment itself! I have seen it all too often in my direct experience. Intellectual shelf life is often more insidious than is physical shelf life.
Beware of jargon
Beware of jargon—learn to recognize it for what it is, a special language to facilitate communication over a restricted area of things or events. But it also blocks thinking outside the original area it was designed to cover. Jargon is both a necessity and a curse.
You cannot consume what is not produced
The only law of economics that I believe in is Hamming’s law: “You cannot consume what is not produced.” There is not another single reliable law in all of economics I know of which is not either a tautology in mathematics or else sometimes false.
I walked the crest of the dune
Thus piece by piece I walked the crest of the dune, and each time the solution slipped on one side or the other I knew what to do to get back on the track.
God loved sand
“God loved sand, He made so much of it.” I heard, inside myself, that we were already having to exploit lower-grade copper mines, and could only expect to have an increasing cost for good copper as the years went by, but the material for glass is widely available and is not likely to ever be in short supply.
The Hawthorne effect
At the Hawthorne plant of Western Electric, long, long ago, some psychologists were trying to improve productivity by making various changes in the environment. They painted the walls an attractive color, and productivity rose. They made the lighting softer, and productivity rose. Each change caused productivity to rise. One of the men got a bit suspicious and sneaked a change back to the original state, and productivity rose! Why? It appears that when you show you care, the person on the other end responds more favorably than if you appear not to care. The workers all thought the changes were being made for their benefit and they responded accordingly. In the field of education, if you tell the students you are using a new method of teaching, then they respond by better performance, and so, incidentally, does the professor. A new method may or may not be better, indeed it may be worse, but the Hawthorne effect, which is not small in the educational area, is likely to indicate that here is a new, important, improved teaching method. It hardly matters what the new method is; its trial will produce improvements if the students perceive it as being done for their benefit.
What you learn for yourself
What you learn from others you can use to follow;
What you learn for yourself you can use to lead.The unreasonable effectiveness of mathematics
We now see that all this “truth” which is supposed to reside in mathematics is a mirage. It is all arbitrary, human conventions.
But we then face the unreasonable effectiveness of mathematics. Having claimed there was neither “truth” nor “meaning” in the mathematical symbols, I am now stuck with explaining the simple fact that mathematics is used and is an increasingly central part of our society, especially in science and engineering. We have passed from absolute certain truth in mathematics to the state where we see there is no meaning at all in the symbols—but we still use them! We put the meaning into the symbols as we convert the assumptions of the problem into mathematical symbols, and again when we interpret the results. Hence we can use the same formula in many different situations—mathematics is sort of a universal mental tool for clear thinking.
What can be put into words
It is not evident, though many people, from the early Greeks on, implicitly act as if it were true, that all things, whatsoever they may be, can be put into words—you could talk about anything: the gods, truth, beauty, and justice. But if you consider what happens in a music concert, then it is obvious that what is transmitted to the audience cannot be put into words—if it could, then the composer and musicians would probably have used words. All the music critics to the contrary, what music communicates cannot (apparently) be put into words. Similarly, but to a lesser extent, for painting. Poetry is a curious field where words are used but the true content of the poem is not in the words!
Initial psychological distance
Creativity seems, among other things, to be “usefully” putting together things which were not perceived to be related before, and it may be the initial psychological distance between the things which counts most.
Tossing an idea around
Can we do anything to increase creativity? There are training courses, and books, as well as “brainstorming sessions” which are supposed to do this. Taking the brainstorming sessions first, while they were very fashionable at one time, they have generally been found to be not much good when formally done, when a brainstorming session is carefully scheduled. But we all have had the experience of “tossing an idea around” with a friend, or a few friends (but not a large group, generally), from which insight, creativity, or whatever you care to call it, arises and we make progress.
Prepare your mind for the future
Probably the most important tool in creativity is the use of an analogy. Something seems like something else which we knew in the past. Wide acquaintance with various fields of knowledge is thus a help—provided you have the knowledge filed away so it is available when needed, rather than to be found only when led directly to it. This flexible access to pieces of knowledge seems to come from looking at knowledge while you are acquiring it from many different angles, turning over any new idea to see its many sides before filing it away. This implies effort on your part not to take the easy, immediately useful “memorizing the material” path, but to prepare your mind for the future.
Stuck with a problem
If you cannot drop a wrong problem, then the first time you meet one you will be stuck with it for the rest of your career.
Experts and impossibility
If an expert says something can be done he is probably correct, but if he says it is impossible then consider getting another opinion.
Always time to fix it later
As the saying goes:
There is never time to do the job right, but there is always time to fix it later,
especially in computer software!
The average adult
Averages are meaningful for homogeneous groups (homogeneous with respect to the actions that may later be taken), but for diverse groups averages are often meaningless. As earlier remarked, the average adult has one breast and one testicle.
Solution to evaluation and back again
A second reason the systems engineer’s design is never completed is the solution offered to the original problem usually produces both deeper insight and dissatisfactions in the engineers themselves.
Furthermore, while the design phase continually goes from proposed solution to evaluation and back again and again, there comes a time when this process of redefinement must stop and the real problem be coped with—thus giving what they realize is, in the long run, a suboptimal solution.
The heart of systems engineering
While the client has some knowledge of his symptoms, he may not understand the real causes of them, and it is foolish to try to cure the symptoms only. Thus while the systems engineers must listen to the client, they should also try to extract from the client a deeper understanding of the phenomena. Therefore, part of the job of a systems engineer is to define, in a deeper sense, what the problem is and to pass from the symptoms to the causes.
Just as there is no definite system within which the solution is to be found, and the boundaries of the problem are elastic and tend to expand with each round of solution, so too there is often no final solution, yet each cycle of input and solution is worth the effort. A solution which does not prepare for the next round with some increased insight is hardly a solution at all.
I suppose the heart of systems engineering is the acceptance that there is neither a definite fixed problem nor a final solution, rather evolution is the natural state of affairs. This is, of course, not what you learn in school, where you are given definite problems which have definite solutions.
