Quantum Computers May Revolutionize Nanotechnology and Drug Design

“Scott Aaronson.” Source of caption and photo: online version of the NYT commentary quoted and cited below.

(p. D5) When people hear that I work on quantum computing — one of the most radical proposals for the future of computation — their first question is usually, “So when can I expect a working quantum computer on my desk?” Often they bring up breathless news reports about commercial quantum computers right around the corner. After I explain the strained relationship between those reports and reality, they ask: “Then when? In 10 years? Twenty?”

Unfortunately, this is sort of like asking Charles Babbage, who drew up the first blueprints for a general-purpose computer in the 1830s, whether his contraption would be hitting store shelves by the 1840s or the 1850s. Could Babbage have foreseen the specific technologies — the vacuum tube and transistor — that would make his vision a reality more than a century later? Today’s quantum computing researchers are in a similar bind. They have a compelling blueprint for a new type of computer, one that could, in seconds, solve certain problems that would probably take eons for today’s fastest supercomputers. But some of the required construction materials don’t yet exist.
. . .
While code-breaking understandably grabs the headlines, it’s the more humdrum application of quantum computers — simulating quantum physics and chemistry — that has the potential to revolutionize fields from nanotechnology to drug design.
. . .
Like fusion power, practical quantum computers are a tantalizing possibility that the 21st century may or may not bring — depending on the jagged course not only of science and technology, but of politics and economics.

Innovative Entrepreneurs Need to Be Able to Fire People

(p. 116) Jobs met with the remaining employees soon after the layoffs and brought his reality distortion field with him. “You’re seeing your friends packing their stuff up and pushing it out to their cars,” Phillips remembered, “and yet somehow he had convinced you that that was the greatest possible thing that could happen.”
Within the Silicon Valley community, the talk was not of the way Jobs had handled his former employees at Pixar, but of his having kept Pixar going at all. It seemed to make little sense from a business point of view. For all his bravado about RenderMan, his motivation was likely a matter of status as much as economics. After his rise and fall at Apple, the onus was on him either to create another success story or to leave his peers to conclude that the first one had been a quirk of fate.
“It wasn’t really working,” Smith said of Pixar’s early years. “In fact, that’s being kind of gentle. We should have failed. But it seemed to me that Steve just would not suffer a defeat. He couldn’t sustain it.”

Lower Grades for Male Spectators When Their Team Wins

(p. C4) Big-time college-football teams may build school spirit, but they also hurt the grades of male students in the bleachers–at least when the teams are winning, a study suggests.

Economists at the University of Oregon tracked the grades of students there (athletes on all teams excluded) from 1999 through 2007, mapping them against the record of the Ducks, whose fortunes varied from season to season.

Simple Heuristics Can Work Better than Complex Formulas

(p. C4) Most business people and physicians privately admit that many of their decisions are based on intuition rather than on detailed cost-benefit analysis. In public, of course, it’s different. To stand up in court and say you made a decision based on what your thumb or gut told you is to invite damages. So both business people and doctors go to some lengths to suppress or disguise the role that intuition plays in their work.
Prof. Gerd Gigerenzer, the director of the Max Planck Institute for Human Development in Berlin, thinks that instead they should boast about using heuristics. In articles and books over the past five years, Dr. Gigerenzer has developed the startling claim that intuition makes our decisions not just quicker but better.
. . .
The economist Harry Markowitz won the Nobel prize for designing a complex mathematical formula for picking fund managers. Yet when he retired, he himself, like most people, used a simpler heuristic that generally works better: He divided his retirement funds equally among a number of fund managers.
A few years ago, a Michigan hospital saw that doctors, concerned with liability, were sending too many patients with chest pains straight to the coronary-care unit, where they both cost the hospital more and ran higher risks of infection if they were not suffering a heart attack. The hospital introduced a complex logistical model to sift patients more efficiently, but the doctors hated it and went back to defensive decision-making.
As an alternative, Dr. Gigerenzer and his colleagues came up with a “fast-and-frugal” tree that asked the doctors just three sequential yes-no questions about each patient’s electrocardiographs and other data. Compared with both the complex logistical model and the defensive status quo, this heuristic helped the doctors to send more patients to the coronary-care unit who belonged there and fewer who did not.

Internet Companies Respect the Value of Your Time

“Arvind Jain, a Google engineer, pointed out the loading speed of individual elements of a website on a test application used to check efficiency, at Google offices in Mountain View, Calif.” Source of caption and photo: online version of the NYT article quoted and cited below.

(p. A1) Wait a second.

No, that’s too long.
Remember when you were willing to wait a few seconds for a computer to respond to a click on a Web site or a tap on a keyboard? These days, even 400 milliseconds — literally the blink of an eye — is too long, as Google engineers have discovered. That barely perceptible delay causes people to search less.
“Subconsciously, you don’t like to wait,” said Arvind Jain, a Google engineer who is the company’s resident speed maestro. “Every millisecond matters.”
Google and other tech companies are on a new quest for speed, challenging the likes of Mr. Jain to make fast go faster. The reason is that data-hungry smartphones and tablets are creating frustrating digital traffic jams, as people download maps, video clips of sports highlights, news updates or recommendations for nearby restaurants. The competition to be the quickest is fierce.
People will visit a Web site less often if it is slower than a close competitor by more than 250 milliseconds (a millisecond is a thousandth of a second).
“Two hundred fifty milliseconds, either slower or faster, is close to the magic number now for competitive advantage on the Web,” said Harry Shum, a computer scientist and speed specialist at Microsoft.
. . .
(p. A3) The need for speed itself seems to be accelerating. In the early 1960s, the two professors at Dartmouth College who invented the BASIC programming language, John Kemeny and Thomas Kurtz, set up a network in which many students could tap into a single, large computer from keyboard terminals.
“We found,” they observed, “that any response time that averages more than 10 seconds destroys the illusion of having one’s own computer.”
In 2009, a study by Forrester Research found that online shoppers expected pages to load in two seconds or fewer — and at three seconds, a large share abandon the site. Only three years earlier a similar Forrester study found the average expectations for page load times were four seconds or fewer.
The two-second rule is still often cited as a standard for Web commerce sites. Yet experts in human-computer interaction say that rule is outdated. “The old two-second guideline has long been surpassed on the racetrack of Web expectations,” said Eric Horvitz, a scientist at Microsoft’s research labs.

Upper Class “Have Lost the Confidence to Preach What They Practice”

(p. 9) The problem, Murray argues, is not that members of the new upper class eat French cheese or vote for Barack Obama. It is that they have lost the confidence to preach what they practice, adopting instead a creed of “ecumenical niceness.” They work, marry and raise children, but they refuse to insist that the rest of the country do so, too. “The belief that being a good American involved behaving in certain kinds of ways, and that the nation itself relied upon a certain kind of people in order to succeed, had begun to fade and has not revived,” Murray writes.

“Crises Are an Inevitable Concomitant of Risk”

(p. 11) Some economic risks are worth taking, and crises are an inevitable concomitant of risk. Crises, like firm failures, can be seen as a manifestation of the Schumpeterian process of creative destruction. The role for economic analysis is to ensure that the creation dominates and that the destruction is not too costly.

“Amazed by the Short-Term Psychology in the Market”

(p. A1) Even after European leaders appeared to have averted a chaotic default by Greece with an eleventh-hour deal for aid, worries persist that a debt disaster on the Continent has merely been delayed.

The tortured process that culminated in that latest bailout has exposed the severe limitations of Europe’s approach to the crisis. Many fear that policy makers simply don’t have the right tools to deal with other troubled countries like Italy, Spain, Ireland and Portugal, a situation that could weigh on the markets and the broader economy.
“I don’t want to be a Cassandra, but the idea that it’s over is an illusion,” said Kenneth S. Rogoff, a professor of economics at Harvard and co-author of “This Time Is Different: Eight Centuries of Financial Folly.” “I am amazed by the short-term psychology in the market.”

Few Jobs from Billions Feds Spent on Green Stimulus

“County Commissioner Rosaura Tijerina supported tax breaks for the Cedro Hill wind farm, but it brought few new jobs.” Source of caption and photo: online version of the WSJ review quoted and cited below.

(p. A1) Alfredo Garcia was among the residents of Webb County, Texas, banking on a windfall from federal stimulus money.

Mr. Garcia expanded his Mexican restaurant from 80 to 120 seats, anticipating a rush of new patrons springing from the nearby Cedro Hill wind farm, a project built with the help of $108 million from U.S. taxpayers.
When construction ended, Cedro Hill had just three employees and Mr. Garcia’s restaurant, Aimee’s, filed for bankruptcy protection. “Nobody came,” said Mr. Garcia, a county judge who closed Aimee’s last year, putting 18 people out of work.
Companies have received more than $10 billion to create jobs and renewable energy by building wind farms, solar projects and other alternatives to oil and natural gas under section 1603 of the American Recovery and Reinvestment Act of 2009. The program expired in December, and President Barack Obama proposed last week that Congress revive it in the 2013 budget.
On federal applications, companies said they created more than 100,000 direct jobs at 1603-funded projects. But a Wall Street Journal investigation found evidence of far fewer. Some plants laid off workers. Others closed.
The discrepancies highlight broader challenges calculating the economic benefits of stimulus spending. Jobs have been an important measure influencing distribution of more than $800 billion in stimulus money, which also has included tax breaks and spending on roads, sewers, schools, health and public assis-(p. A10)tance. Yet the number of jobs created or saved is largely based on formulas, mathematical models and reports by recipients, rather than actual tallies.

Amateurs Can Advance Science

(p. C4) The more specialized and sophisticated scientific research becomes, the farther it recedes from everyday experience. The clergymen-amateurs who made 19th-century scientific breakthroughs are a distant memory. Or are they? Paradoxically, in an increasing variety of fields, computers are coming to the rescue of the amateur, through crowd-sourced science.
Last month, computer gamers working from home redesigned an enzyme. Last year, a gene-testing company used its customers to find mutations that increase or decrease the risk of Parkinson’s disease. Astronomers are drawing amateurs into searching for galaxies and signs of extraterrestrial intelligence. The modern equivalent of the Victorian scientific vicar is an ordinary person who volunteers his or her time to solving a small piece of a big scientific puzzle.
Crowd-sourced science is not a recent invention. In the U.S., tens of thousands of people record the number and species of birds that they see during the Christmas season, a practice that dates back more than a century. What’s new is having amateurs contribute in highly technical areas.

(p. 2) PHONING: A friend of mine bought me an Ideos phone on the street in Kenya for about $80. This is an Android phone that’s a bit smaller than an iPhone, but a lot cheaper. This is really exciting because at that price point, hundreds of thousands and soon millions of smartphones are going to be sold across Africa. The impact for people’s access to knowledge in some very difficult places is enormous.
