“Like so many named places.. it was less an identifiable city than a grouping of concepts– census tracts, special purpose bond-issue districts, shopping nuclei, all overlaid with access roads to its own freeway”*…
Dallas-Fort Worth has one of the world’s most extensive urban freeway systems. It is the product of the pro-growth ambition of political and business leaders, and has empowered the ambition of real estate developers, big business, the technology industry and entrepreneurs. The North Texas cultural spirit to think big and build big has guided the ongoing growth and expansion of Dallas-Fort Worth freeways, a transportation system which has propelled North Texas to be among the most economically successful regions in the United States in the post-World War II era. Dallas-Fort Worth Freeways documents the origins, politics, influence and resulting urban landscape of North Texas freeways…

As we watch for our exit, we might send motile birthday greetings to Nicolas-Joseph Cugnot, he was born on this date in 1725. In 1769, Cugnot, a military engineer, invented the world’s first fuel-propelled vehicle–a gun tractor commissioned by the French government. The following year he produced the first mechanically-driven “horseless carriage”; his steam tricycle, driven by a steam engine, carried four passengers and was the forerunner of the modern motor car.
There are reports of a minor incident in 1771, when the second prototype vehicle is said to have accidentally knocked down a brick or stone wall, either that or a Paris garden or part of the Paris Arsenal walls, in perhaps the first known automobile accident.

Scientists and engineers recognize an elusive but profound difference between precision and accuracy. The two qualities often go hand in hand, of course, but precision involves an ideal of meticulousness and consistency, while accuracy implies real-world truth. When a sharpshooter fires at a target, if the bullets strike close together—clustered, rather than spread out—that is precise shooting. But the shots are only accurate if they hit the bull’s eye. A clock is precise when it marks the seconds exactly and unvaryingly but may still be inaccurate if it shows the wrong time. Perversely, we sometimes value precision at the expense of accuracy…
What makes precision a feature of the modern world is the transition from craftsmanship to mass production. The genius of machine tools—as opposed to mere machines—lies in their repeatability. Artisans of shoes or tables or even clocks can make things exquisite and precise, “but their precision was very much for the few… It was only when precision was created for the many that precision as a concept began to have the profound impact on society as a whole that it does today.” That was John Wilkinson’s achievement in 1776: “the first construction possessed of a degree of real and reproducible mechanical precision—precision that was measurable, recordable, repeatable.”…
Replication and standardization are so hard-wired into our world that we forget how the unstandardized world functioned. A Massachusetts inventor named Thomas Blanchard in 1817 created a lathe that made wooden lasts for shoes. Cobblers still made the shoes, but now the sizes could be systematized. “Prior to that,… shoes were offered up in barrels, at random. A customer shuffled through the barrel until finding a shoe that fit, more or less comfortably.”…

As we contemplate craft, we might send insightful birthday greetings to Lewis Mumford; he was born on this date in 1895. A historian, sociologist, philosopher of technology, and cultural critic, Mumford is probably best remembered for his writings on cities, perhaps especially for his award-winning book The City in History. (See also The City— the extraordinary film that Mumford made with Ralph Steiner and Wiilard Van Dyne, from an outline by the renowned documentarian Pare Lorentz, with a score by Aaron Copland.)
Mumford’s approaches to technology, its history, and its roles in society were acknowledged influences on writers like Jacques Ellul, Witold Rybczynski, Amory Lovins, E. F. Schumacher, Herbert Marcuse, Thomas Merton, and Marshall McLuhan. In a similar way, he was an inspiration for the organicist and environmentalist movements of today.
Unfortunately, once an economy is geared to expansion, the means rapidly turn into an end and “the going becomes the goal.” Even more unfortunately, the industries that are favored by such expansion must, to maintain their output, be devoted to goods that are readily consumable either by their nature, or because they are so shoddily fabricated that they must soon be replaced. By fashion and build-in obsolescence the economies of machine production, instead of producing leisure and durable wealth, are duly cancelled out by the mandatory consumption on an even larger scale.
– Lewis Mumford, The City in History
“I love to talk about nothing. It’s the only thing I know anything about.”*…
The computer you’re reading this article on right now runs on a binary — strings of zeros and ones. Without zero, modern electronics wouldn’t exist. Without zero, there’s no calculus, which means no modern engineering or automation. Without zero, much of our modern world literally falls apart.
Humanity’s discovery of zero was “a total game changer … equivalent to us learning language,” says Andreas Nieder, a cognitive scientist at the University of Tübingen in Germany.
But for the vast majority of our history, humans didn’t understand the number zero. It’s not innate in us. We had to invent it. And we have to keep teaching it to the next generation.
Other animals, like monkeys, have evolved to understand the rudimentary concept of nothing. And scientists just reported that even tiny bee brains can compute zero. But it’s only humans that have seized zero and forged it into a tool.
So let’s not take zero for granted. Nothing is fascinating. Here’s why…
It is indeed fascinating, as you’ll see at “The mind-bendy weirdness of the number zero, explained.”

As we obsess about absence, we might box a dome-shaped birthday cake for inventor, educator, author, philosopher, engineer, and architect R(ichard) Buckminster Fuller; he was born on this date in 1895. “Bucky” most famously developed the geodesic dome, the only large dome that can be set directly on the ground as a complete structure, and the only practical kind of building that has no limiting dimensions (i.e., beyond which the structural strength must be insufficient). But while he never got around to frankfurters, he was sufficiently prolific to have scored over 2,000 patents.
“Fullerenes” (molecules composed entirely of carbon, in the form of a hollow spheres, ellipsoids, or tubes), key components in many nanotechnology applications, were named for Fuller, as their structure mimes that of the geodesic dome. Spherical fullerenes (resembling soccer balls) are also called “buckyballs”; cylindrical ones, carbon nanotubes or “buckytubes.”
I have to say, I think that we are in some kind of final examination as to whether human beings now, with this capability to acquire information and to communicate, whether we’re really qualified to take on the responsibility we’re designed to be entrusted with. And this is not a matter of an examination of the types of governments, nothing to do with politics, nothing to do with economic systems. It has to do with the individual. Does the individual have the courageto really go along with the truth?
God, to me, it seems
is a verb,
not a noun,
proper or improper.

Half a century ago, the pioneers of chaos theory discovered that the “butterfly effect” makes long-term prediction impossible. Even the smallest perturbation to a complex system (like the weather, the economy or just about anything else) can touch off a concatenation of events that leads to a dramatically divergent future. Unable to pin down the state of these systems precisely enough to predict how they’ll play out, we live under a veil of uncertainty.
But now the robots are here to help…
In new computer experiments, artificial-intelligence algorithms can tell the future of chaotic systems. For example, researchers have used machine learning to predict the chaotic evolution of a model flame front like the one pictured above. Learn how– and what it may mean– at “Machine Learning’s ‘Amazing’ Ability to Predict Chaos.”

As we contemplate complexity, we might recall that it was on this date in 1961 that Robert Noyce was issued patent number 2981877 for his “semiconductor device-and-lead structure,” the first patent for what would come to be known as the integrated circuit. In fact another engineer, Jack Kilby, had separately and essentially simultaneously developed the same technology (Kilby’s design was rooted in germanium; Noyce’s in silicon) and had filed a few months earlier than Noyce… a fact that was recognized in 2000 when Kilby was Awarded the Nobel Prize– in which Noyce, who had died in 1990, did not share.

Alexander Fleming’s discovery of penicillin is commonly used as an example of serendipity in science
Scientific folklore is full of tales of accidental discovery, from the stray Petri dish that led Alexander Fleming to discover penicillin to Wilhelm Röntgen’s chance detection of X-rays while tinkering with a cathode-ray tube.
That knowledge often advances through serendipity is how scientists, sometimes loudly, justify the billions of dollars that taxpayers plough into curiosity-driven research each year. And it is the reason some argue that increasing government efforts to control research — with an eye to driving greater economic or social impact — are at best futile and at worst counterproductive.
But just how important is serendipity to science? Scientists debating with policymakers have long relied on anecdotal evidence. Studies rarely try to quantify how much scientific progress was truly serendipitous, how much that cost or the circumstances in which it emerged.
Serendipity can take on many forms, and its unwieldy web of cause and effect is difficult to constrain. Data are not available to track it in any meaningful way. Instead, academic research has focused on serendipity in science as a philosophical concept.
The European Research Council aims to change that…
On the heels of yesterday’s post on the history of dice, and the way they evolved over the centuries to be “fairer”– to favor chance– another post on luck… more specifically in this case, on whether it’s all that it’s cracked up to be. Scientists often herald the role of chance in research; a project in Britain aims to test that popular idea with evidence: “The serendipity test.”

As we contemplate contingency, we might send elaborately-engineered birthday greetings to George Washington Gale Ferris Jr.; he was born on this date in 1859. An engineer and inventor, he had built a successful career testing and inspecting metals for railroads and bridge builders when…
… in 1891, the directors of the World’s Columbian Exposition [to be held in 1893] issued a challenge to American engineers to conceive of a monument for the fair that would surpass the Eiffel Tower, the great structure of the Paris International Exposition of 1889. The planners wanted something “original, daring and unique.” Ferris responded with a proposed wheel from which visitors would be able to view the entire exhibition, a wheel that would “Out-Eiffel Eiffel.” The planners feared his design for a rotating wheel towering over the grounds could not possibly be safe.
Ferris persisted. He returned in a few weeks with several respectable endorsements from established engineers, and the committee agreed to allow construction to begin. Most convincingly, he had recruited several local investors to cover the $400,000 cost of construction. The planning commission of the Exposition hoped that admissions from the Ferris Wheel would pull the fair out of debt and eventually make it profitable. [source]
It carried 2.5 million passengers before it was finally demolished in 1906. But while the Fair’s promoters hopes were fulfilled– the Ferris Wheel was a windfall– Ferris claimed that the exhibition management had robbed him and his investors of their rightful portion of the nearly $750,000 profit that his wheel brought in. Ferris spent two years in litigation, trying (unsuccessfully) to recover his investment. He died despondent and nearly bankrupt (reportedly of typhoid, though some suggest that it was suicide) in 1896.
