evermore, and other beautiful things
An Article by Linus the SephistIf all evidence of civilization on Earth was destroyed, and humans had to re-build society from the ground up, what would be different? Feynman reckons that pivotal scientific moments, like the discovery of the atom, will still happen in the same way. Perhaps mathematics will be similarly rediscovered.
Someone told me once in response to this question, no artwork would ever be recreated. The art we create – music, stories, dance, film – isn’t a fundamental element of the universe, or even of humanity. It’s unique to each artist. If you choose to create art, you leave something in the world that has never had a chance to exist before, and will never again have a chance to exist. There will never be another Beatles or Studio Ghibli or Picasso. Art, in its infinite variations of originality, is cosmically unique in a way the sciences will never be. Art immortalizes human experiences that would otherwise vanish in time.
Reality is Very Weird and You Need to be Prepared for That
An EssayWe might be closer than we think to cures for depression, hypertension, and yes, even obesity.
The answer to scurvy was just one thing, plus a few wrinkles — mostly “not all citrus has the antiscorbutic property” and “most animals can’t get scurvy”. This was only difficult because people weren’t prepared to deal with basic wrinkles, but we can do better by learning from their mistakes.
This means don’t give up easily. It suggests that there is lots of low-hanging fruit, because even simple explanations are easily missed.
Lots of theories have been tried, and lots of them have been given up because of something that looks like contradictory evidence. But the evidence might not actually be a contradiction — the real explanation might just be slightly more complicated than people realized. Go back and revisit scientific near-misses, maybe there’s a wrinkle they didn’t know how to iron out.
Tortured phrases
An Article by Holly ElseIn April 2021, a series of strange phrases in journal articles piqued the interest of a group of computer scientists. The researchers could not understand why researchers would use the terms ‘counterfeit consciousness’, ‘profound neural organization’ and ‘colossal information’ in place of the more widely recognized terms ‘artificial intelligence’, ‘deep neural network’ and ‘big data’.
Further investigation revealed that these strange terms — which they dub “tortured phrases” — are probably the result of automated translation or software that attempts to disguise plagiarism. And they seem to be rife in computer-science papers.
Why Most Published Research Findings Are False
A Research Paper by John P.A. IoannidisThere is increasing concern that most current published research findings are false. The probability that a research claim is true may depend on study power and bias, the number of other studies on the same question, and, importantly, the ratio of true to no relationships among the relationships probed in each scientific field. In this framework, a research finding is less likely to be true when the studies conducted in a field are smaller; when effect sizes are smaller; when there is a greater number and lesser preselection of tested relationships; where there is greater flexibility in designs, definitions, outcomes, and analytical modes; when there is greater financial and other interest and prejudice; and when more teams are involved in a scientific field in chase of statistical significance.
A hypothesis is a liability
A Research Paper by Itai Yanai & Martin LercherThere is a hidden cost to having a hypothesis. It arises from the relationship between night science and day science, the two very distinct modes of activity in which scientific ideas are generated and tested, respectively [1, 2]. With a hypothesis in hand, the impressive strengths of day science are unleashed, guiding us in designing tests, estimating parameters, and throwing out the hypothesis if it fails the tests. But when we analyze the results of an experiment, our mental focus on a specific hypothesis can prevent us from exploring other aspects of the data, effectively blinding us to new ideas.
Suburban Nation
A system for living
Unlike the traditional neighborhood model, which evolved organically as a response to human needs, suburban sprawl is an idealized artificial system. It is not without a certain beauty: it is rational, consistent, and comprehensive. Its performance is largely predictable. It is an outgrowth of modern problem solving: a system for living. Unfortunately, this system is already showing itself to be unsustainable.
The five components of sprawl
The dominant characteristic of sprawl is that each component is strictly segregated from the others.
- Housing subdivisions, also called clusters and pods
- Shopping centers, also called strip centers, shopping malls, and big-box retail
- Office parks and business parks
- Civic institutions
- Roadways
Subdivisions
Subdivisions can be identified as such by their contrived names, which tend toward the romantic—Pheasant Mill Crossing—and often pay tribute to the natural or historic resource they have displaced.
An unmade omelet
The successes of turn-of-the-century planning, represented in America by the City Beautiful movement, became the foundation of a new profession, and ever since, planners have repeatedly attempted to relive that moment of glory by separating everything from everything else. This segregation, once applied only to incompatible uses, is now applied to every use. A typical contemporary zoning code has several dozen land-use designations; not only is housing separated from industry but low-density housing is separated from medium-density housing, which is separated from high-density housing. Medical offices are separated from general offices, which are in turn separated from restaurants and shopping.
As a result, the new American city has been likened to an unmade omelet: eggs, cheese, vegetables, a pinch of salt, but each consumed in turn, raw.
Beauty and function
In truth, a lot of sprawl—primarily affluent areas—could be considered beautiful. This raises a fundamental point: the problem with suburbia is not that it is ugly. The problem with suburbia is that, in spite of all its regulatory controls, it is not functional: it simply does not efficiently serve society or preserve the environment.
Six qualities of traditional neighborhoods
- The center
- The five-minute walk
- The street network
- Narrow, versatile streets
- Mixed use
- Special sites for special buildings
Market segments
The segregation of housing by “market segment” is a phenomenon that was invented by developers who, lacking a meaningful way to distinguish their mass-produced merchandise, began selling the concept of exclusivity: If you live within these gates, you can consider yourself a success.
Cookie cutter
One term that gets a lot of play these days is “cookie cutter.” Developers are mortified about the way this term is used to describe their subdivisions, and they expend a good deal of energy—and money—avoiding it. As much as 20 percent of their construction budget goes toward the application of superficial variety—different shapes, colors, window types, different styles of tack-on ornament, French Provincial next door to California Contemporary. But these efforts are in vain, because beneath the surface articulation is a relentless repetition of the same building. The best way to create real variety is to vary not the architectural style but the building type. Indeed, in places like Georgetown, styles vary only slightly, but one never hears the term cookie cutter, thanks to the wide range of building types.
Worthwhile destinations
Pedestrian life cannot exist in the absence of worthwhile destinations that are easily accessible on foot. This is a condition that modern suburbia fails to satisfy, since it strives to keep all commercial activity well separated from housing.
The twenty-minute house
Despite the way that it sounds, the “twenty-minute house” is not a derogatory label. Quite the opposite—it refers to the fact that a house has only twenty minutes to win the affection of a potential buyer, since that is the average length of a realtor visit. The building industry has responded to this phenomenon by creating a product that is at its best for the first twenty minutes that one is in it.
Like trying to cure obesity by loosening your belt
“Trying to cure traffic congestion by adding more capacity is like trying to cure obesity by loosening your belt.”
Homebuilders
The term homebuilder describes the house as a product that exists independent of its context. This approach would be appropriate if houses floated freely in space, or in some other environment where actual interaction between neighbors was neither possible nor desired. But houses are not meant to exist in isolation, so to think of the individual house as the ultimate outcome of the builder’s craft robs that craft of its broader significance.
The cul-de-sac kid
In this environment where all activities are segregated and distances are measured on the odometer, a child’s personal mobility extends no farther than the edge of the subdivision. Even the local softball field often exists beyond the child’s independent reach.
The result is a new phenomenon: the “cul-de-sac kid,” the child who lives as a prisoner of a thoroughly safe and unchallenging environment.
This “isolation and boredom” is the outcome of an environment that fails to provide teenagers with the ordinary challenges of maturing, developing useful skills, and gaining a sense of self.
On-site parking
Most cities require new and renovated buildings to provide their own parking on site. This is probably the single greatest killer of urbanism in the United States today. It prevents the renovation of old buildings, since there is inadequate room on their sites for new parking; it encourages the construction of anti-pedestrian building types in which the building sits behind or hovers above a parking lot; it eliminates street life, since everyone parks immediately adjacent to their destination and has no reason to use the sidewalk; finally, it results in a low density of development that can keep a downtown from achieving critical mass.
Architectural mysticism
In response to their growing sense of insignificance, some architects have tried to regain a sense of power through what can best be described as mysticism. By importing arcane ideas from unrelated disciplines—such as contemporary French literary theory (now outdated) —by developing illegible techniques of representation, and by shrouding their work in inscrutable jargon, designers are creating increasingly smaller realms of communication, in order that they might inhabit a domain in which they possess some degree of control. Nowhere is this crisis more evident than in the most prestigious architecture schools.
