Invention Requires More than Just Necessity

If necessity is the mother of invention, why did it take 2,000 years for necessity to give birth?

(p. D2) Archaeological evidence suggests that after setting sail from the Solomon Islands, people crossed more than 2,000 miles of open ocean to colonize islands like Tonga and Samoa. But after 300 years of island hopping, they halted their expansion for 2,000 years more before continuing — a period known as the Long Pause that represents an intriguing puzzle for researchers of the cultures of the South Pacific.
“Why is it that the people stopped for 2,000 years?” said Dr. Montenegro. “Clearly they were interested and capable. Why did they stop after having great success for a great time?”
To answer these questions, Dr. Montenegro and his colleagues ran numerous voyage simulations and concluded that the Long Pause that delayed humans from reaching Hawaii, Tahiti and New Zealand occurred because the early explorers were unable to sail through the strong winds that surround Tonga and Samoa. They reported their results last week in the journal of the Proceedings of the National Academy of Sciences.
“Our paper supports the idea that what people needed was boating technology or navigation technology that would allow them to move efficiently against the wind,” Dr. Montenegro said.

Video Gamers Become “More Optimistic, Creative, Courageous and Determined”

(p. 10) The principles of game design, McGonigal argues, can be used to turn not only leisure into productivity, but also sickness into health. By reframing recuperative tasks such as going for a walk, reconnecting with a friend or writing a short story as gamelike quests, healing can be systematized. Moreover, when you begin to tackle these life quests (McGonigal provides nearly 100 examples) you will, she writes, enter a “gameful” state, becoming more optimistic, creative, courageous and determined. By applying the psychological attributes that games unlock to real-world scenarios, we become like Mario as he guzzles a power-up and transforms into Super Mario.
McGonigal’s promises come thick and early, propped up by the results of two clinical studies. The 30-day program contained in the book will, she writes, “significantly” reduce symptoms of depression and anxiety and decrease suffering. It will increase optimism, make you “more satisfied” and even lead, incredibly, to a life “free of regret.” McGonigal claims that every day for more than five years she has heard from someone telling her that the program changed his or her life.

Vacuum Tubes May Be Revived

(p. B1) PASADENA, Calif. — The future of computing may be in its past.
The silicon transistor, the tiny switch that is the building block of modern microelectronics, replaced the vacuum tube in many consumer products in the 1970s. Now as shrinking transistors to even more Lilliputian dimensions is becoming vastly more challenging, the vacuum tube may be on the verge of a comeback.
. . .
The Achilles’ heel of today’s transistors is the smaller they get, the more they leak electrons. In modern computer chips, as much as half of the power consumed is lost to electrons leaking from transistors that are only dozens of atoms wide. Those electrons waste energy and generate heat.
In contrast, Dr. Scherer’s miniature vacuum tube switches perform a jujitsu move by using the same mechanism that causes leakage in transistors — known by physicists as quantum tunneling — to switch on and off the flow of electrons without leakage. As a result, he believes that modern vacuum tube circuits have the potential to use less power and work faster than today’s transistor-based chips.
. . .
Vacuum tubes are one of a range of ideas that engineers are looking at as they work to create chips that can do more while using less power. Other promising approaches include exotic materials such as carbon nanotubes and even microscopic mechanical switches that can be opened and closed just like an electronic gate.

Blockchain Can Cut Out Financial Middlemen

(p. A9) Blockchains are basically a much better way of managing information. They are distributed ledgers, run on multiple computers all over the world, for recording transactions in a way that is fast, limitless, secure and transparent. There is no central database overseen by a single institution responsible for auditing and recording what goes on. If you and I were to engage in a transaction, it would be executed, settled and recorded on the blockchain and evident for all to see, yet encrypted so as to be villain-proof. “The new platform enables a reconciliation of digital records regarding just about everything in real time,” write the Tapscotts. No more waiting for that check to clear. It would all be done and recorded for eternity before you know it.
The digital currency bitcoin is currently the best-known blockchain technology. If I wanted to pay you using bitcoin, I would start with a bitcoin wallet on my computer or phone and buy bitcoins using dollars. I would then send you a message identifying the bitcoin I would like to send you and sign the transaction using a private key. The heavily encrypted reassignment of the bitcoin to your wallet is recorded and verified in the bitcoin ledger for all to see, and they are now yours to spend. The transaction is likely more secure and cheaper than a traditional bank transfer.
. . .
The layman, . . . , might want to wait for a more penetrable explanation of blockchains to come along–as one surely will if the authors’ predictions are even one-zillionth right.​

Space Trash Start-Up Aims to Be Quicker than Government

(p. D1) Mr. Okada is an entrepreneur with a vision of creating the first trash collection company dedicated to cleaning up some of humanity’s hardest-to-reach rubbish: the spent rocket stages, inert satellites and other debris that have been collecting above Earth since Sputnik ushered in the space age. He launched Astroscale three years ago in the belief that national space agencies were dragging their feet in facing the problem, which could be tackled more quickly by a small private company motivated by profit.
“Let’s face it, waste management isn’t sexy enough for a space agency to convince taxpayers to allocate money,” said Mr. Okada, 43, who put Astroscale’s headquarters in start-up-friendly Singapore but is building its spacecraft in his native Japan, where he found more engineers. “My breakthrough is figuring out how to make this into a business.”
. . .
(p. D3) “The projects all smelled like government, not crisp or quick,” he said of conferences he attended to learn about other efforts. “I came from the start-up world where we think in days or weeks, not years.”
. . .
He also said that Astroscale would start by contracting with companies that will operate big satellite networks to remove their own malfunctioning satellites. He said that if a company has a thousand satellites, several are bound to fail. Astroscale will remove these, allowing the company to fill the gap in its network by replacing the failed unit with a functioning satellite.
“Our first targets won’t be random debris, but our clients’ own satellites,” he said. “We can build up to removing debris as we perfect our technology.”

Gates Foundation Funding “Second Green Revolution”

(p. A12) URBANA, Ill. — A decade ago, agricultural scientists at the University of Illinois suggested a bold approach to improve the food supply: tinker with photosynthesis, the chemical reaction powering nearly all life on Earth.
The idea was greeted skeptically in scientific circles and ignored by funding agencies. But one outfit with deep pockets, the Bill and Melinda Gates Foundation, eventually paid attention, hoping the research might help alleviate global poverty.
Now, after several years of work funded by the foundation, the scientists are reporting a remarkable result.
Using genetic engineering techniques to alter photosynthesis, they increased the productivity of a test plant — tobacco — by as much as 20 percent, they said Thursday[November 17, 2016] in a study published by the journal Science. That is a huge number, given that plant breeders struggle to eke out gains of 1 or 2 percent with more conventional approaches.
The scientists have no interest in increasing the production of tobacco; their plan is to try the same alterations in food crops, and one of the leaders of the work believes production gains of 50 percent or more may ultimately be achievable. If that prediction is borne out in further research — it could take a decade, if not longer, to know for sure — the result might be nothing less than a transformation of global agriculture.
. . .
“We’re here because we want to alleviate poverty,” said Katherine Kahn, the officer at the Gates Foundation overseeing the grant for the Illinois research. “What is it (p. A24) the farmers need, and how can we help them get there?”
One of the leaders of the research, Stephen P. Long, a crop scientist who holds appointments at the University of Illinois at Urbana-Champaign and at Lancaster University in England, emphasized in an interview that a long road lay ahead before any results from the work might reach farmers’ fields.
But Dr. Long is also convinced that genetic engineering could ultimately lead to what he called a “second Green Revolution” that would produce huge gains in food production, like the original Green Revolution of the 1960s and 1970s, which transferred advanced agricultural techniques to some developing countries and led to reductions in world hunger.
. . .
The work is, in part, an effort to secure the food supply against the possible effects of future climate change. If rising global temperatures cut the production of food, human society could be destabilized, but more efficient crop plants could potentially make the food system more resilient, Dr. Long said.

Making Technologies Useful to End Users Can Be Hard

Sharma’s theory sounds somewhat similar to that of Bhidé in his The Venturesome Economy.

(p. B4) Anshu​ Sharma,​ a venture capitalist at Storm Ventures, thinks he knows why so many companies that should have all the resources and brainpower required to build the next big thing so often fail to. He calls his thesis the “stack fallacy,” and though he sketched its outline in a recent essay, I found it so compelling that I thought it worth a more thorough exploration of the implications of his theory. What follows is the result of that conversation.

“Stack fallacy is the mistaken belief that it is trivial to build the layer above yours,” Mr. Sharma wrote. And as someone who worked at both Oracle and Salesforce, his exhibit A is these two companies. To Oracle, which is primarily a database company, Salesforce is just a “hosted database app,” he wrote. and yet despite spending millions on it, Oracle has been unable to beat Salesforce in Salesforce’s core competency, notably customer-relations management software.
It helps to understand that in tech, the “stack” is the layer cake of technology, one level of abstraction sitting atop the next, that ultimately delivers a product or service to the user. On the Internet, for example, there is a stack of technologies stretching from the server through the operating system running on it through a cloud abstraction layer and then the apps running atop that, until you reach the user. Even the electricity grid required to power the data center in which the server lives could be considered part of the technology “stack” of, say, your favorite email service.
. . .
The reason that companies fail when they try to move up the stack is simple, argues Mr. Sharma: They don’t have firsthand empathy for what customers of the product one level above theirs in the stack actually want. Database engineers at Oracle don’t know what supply-chain managers at Fortune 500 companies want out of an enterprise resource-planning system like SAP, but that hasn’t stopped Oracle from trying to compete in that space.

Modern Technology Adds to Knowledge of Culture and Religion

(p. A6) Nearly half a century ago, archaeologists found a charred ancient scroll in the ark of a synagogue on the western shore of the Dead Sea.
The lump of carbonized parchment could not be opened or read. Its curators did nothing but conserve it, hoping that new technology might one day emerge to make the scroll legible.
Just such a technology has now been perfected by computer scientists at the University of Kentucky. Working with biblical scholars in Jerusalem, they have used a computer to unfurl a digital image of the scroll.
It turns out to hold a fragment identical to the Masoretic text of the Hebrew Bible and, at nearly 2,000 years old, is the earliest instance of the text.
The writing retrieved by the computer from the digital image of the unopened scroll is amazingly clear and legible, in contrast to the scroll’s blackened and beaten-up exterior. “Never in our wildest dreams did we think anything would come of it,” said Pnina Shor, the head of the Dead Sea Scrolls Project at the Israel Antiquities Authority.
Scholars say this remarkable new technique may make it possible to read other scrolls too brittle to be unrolled.
. . .
The experts say this new method may make it possible to read other ancient scrolls, including several Dead Sea scrolls and about 300 carbonized ones from Herculaneum, which were destroyed by the volcanic eruption of Mount Vesuvius in A.D. 79.
. . .
The feat of recovering the text was made possible by software programs developed by W. Brent Seales, a computer scientist at the University of Kentucky. Inspired by the hope of reading the many charred and unopenable scrolls found at Herculaneum, near Pompeii in Italy, Dr. Seales has been working for the last 13 years on ways to read the text inside an ancient scroll.
. . .
He succeeded in 2009 in working out the physical structure of the ruffled layers of papyrus in a Herculaneum scroll.
He has since developed a method, called virtual unwrapping, to model the surface of an ancient scroll in the form of a mesh of tiny triangles. Each triangle can be resized by the computer until the virtual surface makes the best fit to the internal structure of the scroll, as revealed by the scanning method. The blobs of ink are assigned to their right place on the structure, and the computer then unfolds the whole 3-D structure into a 2-D sheet.

Denmark Drones Saving Lives

(p. B1) Mr. McLinden is a member of a group of middle-aged emergency workers taking part in a trial to jump-start the use of unmanned aircraft by Europe’s emergency services. The goal is to give the region a head start over the United States and elsewhere in using drones to tackle real-world emergencies.
The “drone school” builds on Europe’s worldwide lead in giving public groups and companies relatively free rein to experiment with unmanned aircraft. If everything goes as planned, the project’s backers hope government agencies in Europe and farther afield can piggyback on the experiences, helping to transform drones from recreational toys to lifesaving tools.
“For us, this technology is a game-changer,” said Mr. McLinden, who traveled to Copenhagen (p. B4) for a three-day training course with two colleagues from the Mid and West Wales Fire and Rescue Service. They will start offering 24/7 drone support — allowing colleagues, for example, to monitor accidents from 300 feet above — across central Wales later this month.
“Drones aren’t going to replace what we do,” Mr. McLinden added. “But anything that we can do to give our crews an advantage, that’s great.”
. . .
In a somewhat stuffy classroom at a disused fire station in Copenhagen, Thomas Sylvest gave advice to Mr. McLinden and others from his two years of flying. As Denmark’s first, and so far only, emergency service drone pilot, Mr. Sylvest has responded to things as varied as missing person cases and fires, often receiving calls late at night.
Mr. Sylvest, a fast-talking 50-year-old, offered tips on how best to share videos streamed directly from drones to commanders on the ground. During a recent fire in downtown Copenhagen, Mr. Sylvest said, he was able to beam high-definition images from high above, allowing his bosses to judge if a building’s walls would collapse (they did not). And when the police called him out last year after a man was reported missing, he flew his drone along a stretch of train tracks to guide colleagues on where best to look. (The man was found.)

Crony Credentialism Is Regulatory Barrier to Telemedicine

(p. A11) Telemedicine has made exciting advances in recent years. Remote access to experts lets patients in stroke, neonatal and intensive-care units get better treatment at a lower cost than ever before. In rural communities, the technology improves timely access to care and reduces expensive medevac trips. Remote-monitoring technology lets patients with chronic conditions live at home rather than in an assisted-living facility.
Yet while telemedicine can connect a patient in rural Idaho with top specialists in New York, it often runs into a brick wall at state lines. Instead of welcoming the benefits of telemedicine, state governments and entrenched interests use licensing laws to make it difficult for out-of-state experts to offer remote care.
. . .
Using its power under the Commerce Clause of the Constitution, Congress could pass legislation to define where a physician practices medicine to be the location of the physician, rather than the location of the patient, as states currently do. Physicians would need only one license, that of their home state, and would work under its particular rules and regulations.
This would allow licensed physicians to treat patients in all 50 states. It would greatly expand access to quality medical care by freeing millions of patients to seek services from specialists around the country without the immense travel costs involved.

Creative Destruction of Polaroid by Digital Photography

(p. A17) There aren’t many 3-year-olds who can take credit for inspiring a revolution in the way millions of people view the world. According to a legend that begins Peter Buse’s welcome history of the Polaroid company, “The Camera Does the Rest,” it was engineer Edwin Land’s daughter, Jennifer, who asked one evening in 1943 why it took so long to view the photographs that the family had shot while on vacation in Santa Fe, N.M. Land set out on a walk to ponder that question and, so the story goes, returned six hours later with an answer that would transform the hidebound practice of photography: the instant snapshot.
. . .
“In 1974 alone there were about 1 billion Polaroid images made, and by 1976 . . . 15 billion in total,” the author writes, “and this before the real explosion in Polaroid photography in the late 1970s and early 1980s.” The party might have gone on forever had it not been for the same type of creative destruction that Polaroid itself had stirred up in the 1940s–this time brought about by the digital revolution.
By the time the company joined that revolution in the 1990s, it was too late. Their digital products were inferior to those being turned out by competing companies. Polaroid had always done well selling cameras, but the real money was in the film, the demand for which was falling precipitately. In July 1997, the company’s stock price was $60.51. Four years later, as the company spiraled toward bankruptcy, it was $0.49. The author writes that Polaroid joined the “analog scrap heap” that included “vinyl turntables and the Sony Walkman.”​
