Amish Factory Uses Pneumatics in Place of Electricity

(p. 219) The Amish also make a distinction between technology they have at work and technology they have at home. I remember an early visit to an Amish man who ran a woodworking shop near Lancaster, Pennsylvania. . . .
. . .
(p. 220) While the rest of his large workshop lacked electricity beyond that naked bulb, it did not lack power machines. The place was vibrating with an ear-cracking racket of power sanders, power saws, power planers, power drills, and so on. Everywhere I turned there were bearded men covered in sawdust pushing wood through screaming machines. This was not a circle of Renaissance craftsman hand-tooling masterpieces. This was a small-time factory cranking out wooden furniture with machine power. But where was the power coming from? Not from windmills.
Amos took me around to the back where a huge SUV-sized diesel generator sat. It was massive. In addition to a gas engine there was a very large tank, which, I learned, stored compressed air. The diesel engine burned petroleum fuel to drive the compressor that filled the reservoir with pressure. From the tank, a series of high-pressure pipes snaked off toward every corner of the factory. A hard rubber flexible hose connected each tool to a pipe. The entire shop ran on compressed air. Every piece of machinery was running on pneumatic power. Amos even showed me a pneumatic switch, which he could flick like a light switch to turn on some paint-drying fans running on air.
The Amish call this pneumatic system “Amish electricity.” At first, pneumatics were devised for Amish workshops, but air power was seen as so useful that it migrated to Amish households. In fact, there is an entire cottage industry in retrofitting tools and appliances to run on Amish electricity. The retrofitters buy a heavy-duty blender, say, and yank out the electrical motor. They then substitute an air-powered motor of appropriate size, add pneumatic connectors, and bingo, your Amish mom now has a blender in her electricity-less kitchen. You can get a pneumatic sewing machine and a pneumatic washer/dryer (with propane heat). In a display of pure steam-punk (air-punk?) nerdiness, Amish hackers try to outdo one another in building pneumatic versions of electrified contraptions. Their mechanical skill is quite impressive, particularly since none went to school beyond the eighth grade. They (p. 221) love to show off their geekiest hacks. And every tinkerer I met claimed that pneumatics were superior to electrical devices because air was more powerful and durable, outlasting motors that burned out after a few years of hard labor. I don’t know if this claim of superiority is true or merely a justification, but it was a constant refrain.

If Anarcho-Primitives Destroy Civilization, Billions of City-Dwellers Will Die

(p. 211) . . . , the . . . problem with destroying civilization as we know it is that the alternative, such as it has been imagined by the self-described “haters of civilization,” would not support but a fraction of the people alive today. In other words, the collapse of civilization would kill billions. Ironically, the poorest rural inhabitants would fare the best, as they could retreat to hunting and gathering with the least trouble, but billions of urbanites would die within months or even weeks, once food ran out and disease took over. The anarcho-primitives are rather sanguine about this catastrophe, arguing that accelerating the collapse early might save lives in total.

Patents Turned Steam from Toy to Engine

Source of book image: http://img2.imagesbn.com/p/9781400067053_p0_v1_s260x420.JPG

(p. 20) The obvious audience for Rosen’s book consists of those who hunger to know what it took to go from Heron of Alexandria’s toy engine, created in the first century A.D., to practical and brawny beasts like George and Robert Stephenson’s Rocket, which kicked off the age of steam locomotion in 1829. But Rosen is aiming for more than a fan club of steam geeks. The “most powerful idea” of his title is not an early locomotive: “The Industrial Revolution was, first and foremost, a revolution in invention,” he writes, “a radical transformation in the process of invention itself.” The road to Rocket was built with hundreds of innovations large and small that helped drain the mines, run the mills, and move coal and then people over rails.
. . .
Underlying it all, Rosen argues, was the recognition that ideas themselves have economic value, which is to say, this book isn’t just gearhead wonkery, it’s legal wonkery too. Abraham Lincoln, wondering why Heron’s steam engine languished, claimed that the patent system “added the fuel of interest to the fire of genius.” Rosen agrees, offering a forceful argument in the debate, which has gone on for centuries, over whether patents promote innovation or retard it.
Those who believe passionately, as Thomas Jefferson did, that inventions “cannot, in nature, be a subject of property,” are unlikely to be convinced. Those who agree with the inventors James Watt and Richard Arkwright, who wrote in a manuscript that “an engineer’s life without patent is not worthwhile,” will cheer. Either way, Rosen’s presentation of this highly intellectual debate will reward even those readers who never wondered how the up-and-down chugging of a piston is converted into consistent rotary motion.

Moore’s Law: Inevitable or Intel?

I believe that Moore’s Law remained true for a long time, not because it was inevitable, but because an exemplary company worked very hard and effectively to make it true.

(p. 159) In brief, Moore’s Law predicts that computing chips will shrink by half in size and cost every 18 to 24 months. For the past 50 years it has been astoundingly correct.

It has been steady and true, but does Moore’s Law reveal an imperative in the technium? In other words is Moore’s Law in some way inevitable? The answer is pivotal for civilization for several reasons. First, Moore’s Law represents the acceleration in computer technology, which is accelerating everything else. Faster jet engines don’t lead to higher corn yields, nor do better lasers lead to faster drug discoveries, but faster computer chips lead to all of these. These days all technology follows computer technology. Second, finding inevitability in one key area of technology suggests invariance and directionality may be found in the
rest of the technium.

Faculty Unions Oppose MOOCs that Might Cost Them Their Jobs in Five to Seven Years

(p. A1) SAN JOSE, Calif. — Dazzled by the potential of free online college classes, educators are now turning to the gritty task of harnessing online materials to meet the toughest challenges in American higher education: giving more students access to college, and helping them graduate on time.
. . .
Here at San Jose State, . . . , two pilot programs weave material from the online classes into the instructional mix and allow students to earn credit for them.
“We’re in Silicon Valley, we (p. A3) breathe that entrepreneurial air, so it makes sense that we are the first university to try this,” said Mohammad Qayoumi, the university’s president. “In academia, people are scared to fail, but we know that innovation always comes with the possibility of failure. And if it doesn’t work the first time, we’ll figure out what went wrong and do better.”
. . .
Dr. Qayoumi favors the blended model for upper-level courses, but fully online courses like Udacity’s for lower-level classes, which could be expanded to serve many more students at low cost. Traditional teaching will be disappearing in five to seven years, he predicts, as more professors come to realize that lectures are not the best route to student engagement, and cash-strapped universities continue to seek cheaper instruction.
“There may still be face-to-face classes, but they would not be in lecture halls,” he said. “And they will have not only course material developed by the instructor, but MOOC materials and labs, and content from public broadcasting or corporate sources. But just as faculty currently decide what textbook to use, they will still have the autonomy to choose what materials to include.”
. . .
Any wholesale online expansion raises the specter of professors being laid off, turned into glorified teaching assistants or relegated to second-tier status, with only academic stars giving the lectures. Indeed, the faculty unions at all three California higher education systems oppose the legislation requiring credit for MOOCs for students shut out of on-campus classes.
. . .
“Our ego always runs ahead of us, making us think we can do it better than anyone else in the world,” Dr. Ghadiri said. “But why should we invent the wheel 10,000 times? This is M.I.T., No. 1 school in the nation — why would we not want to use their material?”
There are, he said, two ways of thinking about what the MOOC revolution portends: “One is me, me, me — me comes first. The other is, we are not in this business for ourselves, we are here to educate students.”

Edison, Not Muybridge, Remains the Father of Hollywood

Source of book image: online version of the WSJ review quoted and cited below.

(p. A13) Wish it though we might, this strangely off-center Briton isn’t really the Father of Hollywood, nor even a distant progenitor of “Avatar.” The famous time-lapse images that he took for Stanford, proving that a horse does take all four hoofs off the ground while galloping–and the tens of thousands of photographs that he went on to make of birds flying and people sneezing or bending over and picking things up–were soon so comprehensively overtaken by newer technologies (lenses, shutters, celluloid) that his stature as a proto-movie-maker was soon reduced to a way-station. His contribution was technically interesting but hardly seminal at all. The tragic reality is that Thomas Edison, with whom Muybridge was friendly enough to propose collaboration, retains the laurels–though, as Mr. Ball points out with restrained politeness, Muybridge might have fared better had he been aware of Edison’s reputation for “borrowing the work of others and not returning it.”

Tesla CTO Straubel Likes Biography of Tesla

J.B. Straubel, Chief Technology Officer of Tesla Motors. Source of photo: online version of the NYT article quoted and cited below.

(p. 2) J. B. Straubel is a founder and the chief technical officer of Tesla Motors in Palo Alto, Calif. The company makes electric vehicles that some compare to Apple products in terms of obsessive attention to design, intuitive user interface and expense.

READING I like to read biographies of interesting people, mostly scientists and engineers. Right now, it’s “Steve Jobs,” by Walter Isaacson. One of my favorites biographies was “Wizard: The Life and Times of Nikola Tesla,” by Marc Seifer, which I read even before Tesla Motors started.
. . .
WATCHING I really like the movie “October Sky.” It’s about a guy who grew up in a little coal-mining town around the time of Sputnik. He fell in love with the idea of building rockets and the movie follows him through his high school years when he’s building rockets and eventually he ends up becoming an engineer at NASA. I watch it every year or so. It’s inspirational. I always come out of it wanting to work harder.

Paul Allen’s Account of the Founding of Microsoft

Source of book image: http://www.entrepreneur.com/dbimages/slideshow/idea-man-paul-allen.jpg

(p. C6) The first half of “Idea Man” sets forth Mr. Allen’s version of the Microsoft creation myth, depicting Mr. Gates as a petulant, ambitious and money-minded mogul-to-be and Mr. Allen as an underappreciated visionary. Pictures of them from the 1970s and early ’80s also tell this story, making Mr. Allen look like a hirsute, powerful older brother and Mr. Gates like a kid.
. . .
“Idea Man” is long overdue. It turns out to be as remote, yet as surpassingly strange, as its author, whose receipt of a diagnosis of Stage 4 non-Hodgkin’s lymphoma in 2009 has made it that much more important for him to tell his story. Though it is written in the smoothly proficient style of many a collaborator-assisted memoir, it is a book filled with wild extremes: breakthrough, breakup, power, indulgence, blue-sky innovation. And it winds up offering Mr. Allen’s guarded, partial answer to a universal question: what if you could make your wildest dreams come true?

MOOCs “Will Really Scale” Once Credible Credentialing Process Is Mastered

A “MOOC” is a “massive open online course.”

(p. 1) Last May I wrote about Coursera — co-founded by the Stanford computer scientists Daphne Koller and Andrew Ng — just after it opened. Two weeks ago, I went back out to Palo Alto to check in on them. When I visited last May, about 300,000 people were taking 38 courses taught by Stanford professors and a few other elite universities. Today, they have 2.4 million students, taking 214 courses from 33 universities, including eight international ones.

Anant Agarwal, the former director of M.I.T.’s artificial intelligence lab, is now president of edX, a nonprofit MOOC that M.I.T. and Harvard are jointly building. Agarwal told me that since May, some 155,000 students from around the world have taken edX’s first course: an M.I.T. intro class on circuits. “That is greater than the total number of M.I.T. alumni in its 150-year history,” he said.
. . .
(p. 11) As we look to the future of higher education, said the M.I.T. president, L. Rafael Reif, something that we now call a “degree” will be a concept “connected with bricks and mortar” — and traditional on-campus experiences that will increasingly leverage technology and the Internet to enhance classroom and laboratory work. Alongside that, though, said Reif, many universities will offer online courses to students anywhere in the world, in which they will earn “credentials” — certificates that testify that they have done the work and passed all the exams. The process of developing credible credentials that verify that the student has adequately mastered the subject — and did not cheat — and can be counted on by employers is still being perfected by all the MOOCs. But once it is, this phenomenon will really scale.
I can see a day soon where you’ll create your own college degree by taking the best online courses from the best professors from around the world — some computing from Stanford, some entrepreneurship from Wharton, some ethics from Brandeis, some literature from Edinburgh — paying only the nominal fee for the certificates of completion. It will change teaching, learning and the pathway to employment. “There is a new world unfolding,” said Reif, “and everyone will have to adapt.”

Modern Cities Are “Successful Former Slums” that Allowed “Vibrant Economic Activity”

(p. 82) Babylon, London, and New York all had teeming ghettos of unwanted settlers erecting shoddy shelters with inadequate hygiene and engaging in dodgy dealings. Historian Bronislaw Geremek states that “slums constituted a large part of the urban landscape” of Paris in the Middle Ages. Even by the 1780s, when Paris was at its peak, nearly 20 percent of its residents did not have a “fixed abode”–that is, they lived in shacks. In a familiar complaint about medieval French cities, a gentleman from that time noted: “Several families inhabit one house. A (p. 83) weaver’s family may be crowded into a single room, where they huddle around a fireplace.” That refrain is repeated throughout history. A century ago Manhattan was home to 20,000 squatters in self-made housing. Slab City alone, in Brooklyn (named after the use of planks stolen from lumber mills), contained 10,000 residents in its slum at its peak in the 1880s. In the New York slums, reported the New York Times in 1858, “nine out of ten of the shanties have only one room, which does not average over twelve feet square, and this serves all the purposes of the family.”
San Francisco was built by squatters. As Rob Neuwirth recounts in his eye-opening book Shadow Cities, one survey in 1855 estimated that “95 percent of the property holders in [San Francisco] would not be able to produce a bona fide legal title to their land.” Squatters were everywhere, in the marshes, sand dunes, military bases. One eyewitness said, “Where there was a vacant piece of ground one day, the next saw it covered with half a dozen tents or shanties.” Philadelphia was largely settled by what local papers called “squatlers.” As late as 1940, one in five citizens in Shanghai was a squatter. Those one million squatters stayed and kept upgrading their slum so that within one generation their shantytown became one of the first twenty-first-century cities.
That’s how it works. This is how all technology works. A gadget begins as a junky prototype and then progresses to something that barely works. The ad hoc shelters in slums are upgraded over time, infrastructure is extended, and eventually makeshift services become official. What was once the home of poor hustlers becomes, over the span of generations, the home of rich hustlers. Propagating slums is what cities do, and living in slums is how cities grow. The majority of neighborhoods in almost every modern city are merely successful former slums. The squatter cities of today will become the blue-blood neighborhoods of tomorrow. This is already happening in Rio and Mumbai today.
Slums of the past and slums of today follow the same description. The first impression is and was one of filth and overcrowding. In a ghetto a thousand years ago and in a slum today shelters are haphazard and dilapidated. The smells are overwhelming. But there is vibrant economic activity.

Technology Brings Choices and Control, Which Brings Happiness

(p. 78) For the past 30 years the conventional wisdom has been that once a person achieves a minimal standard of living, more money does not bring more happiness. If you live below a certain income threshold, increased money makes a difference, but after that, it doesn’t buy happiness. That was the conclusion of a now-classic study by Richard Easterlin in 1974. However, recent research from the Wharton School at the University of Pennsylvania shows that worldwide, affluence brings increased satisfaction. Higher income earners are happier. Citizens in higher-earning countries tend to be more satisfied on average.
My interpretation of this newest research–which also matches our intuitive impressions–is that what money brings is increased choices, rather than merely increased stuff (although more stuff comes with the territory). We don’t find happiness in more gadgets and experiences. We do find happiness in having some control of our time and work, a chance for real leisure, in the escape from the uncertainties of war, poverty, and corruption, and in a chance to pursue individual freedoms–all of which come with increased affluence.
I’ve been to many places in the world, the poorest and the richest spots, the oldest and the newest cities, the fastest and the slowest cultures, and it is my observation that when given a chance, people who walk will buy a bicycle, people who ride a bike will get a scooter, people riding a scooter will upgrade to a car, and those with a car dream of a plane. Farmers everywhere trade their ox plows for tractors, their gourd bowls for tin ones, their sandals for shoes. Always. Insignificantly few ever go back. The exceptions such as the well-known Amish are not so exceptional when examined closely, for even their communities adopt selected technology without retreat.
