What would happen if the earth's rotation slowed down and finally stopped spinning over a period of a few decades? ArcGIS lets us model the effects of this scenario, performing calculations and estimations and creating a series of maps showing the effects the absence of centrifugal force would have on sea level.

The lack of the centrifugal effect would result in the gravity of the earth being the only significant force controlling the extent of the oceans. Prominent celestial bodies such as the moon and sun would also play a role, but because of their distance from the earth, their impact on the extent of global oceans would be negligible.

If the earth's gravity alone was responsible for creating a new geography, the huge bulge of oceanic water—which is now about 8 km high at the equator—would migrate to where a stationary earth's gravity would be the strongest.

GURGAON, India

In Gurgaon, economic growth is often the product of a private sector improvising to overcome the inadequacies of the government. To compensate for electricity blackouts, Gurgaon’s companies and real estate developers operate massive diesel generators capable of powering small towns. No water? Drill private borewells. No public transportation? Companies employ hundreds of private buses and taxis. Worried about crime? Gurgaon has almost four times as many private security guards as police officers.

Gurgaon was widely regarded as an economic wasteland. In 1979, the state of Haryana created Gurgaon by dividing a longstanding political district on the outskirts of New Delhi. One half would revolve around the city of Faridabad, which had an active municipal government, direct rail access to the capital, fertile farmland and a strong industrial base. The other half, Gurgaon, had rocky soil, no local government, no railway link and almost no industrial base. As an economic competition, it seemed an unfair fight. And it has been: Gurgaon has won, easily. Faridabad has struggled to catch India’s modernization wave, while Gurgaon’s disadvantages turned out to be advantages, none more important, initially, than the absence of a districtwide government, which meant less red tape capable of choking development. By 1979, Mr. Singh had taken control of his father-in-law’s real estate company, now known as DLF, at a moment when urban development in India was largely overseen by government agencies. In most states, private developers had little space to operate, but Haryana was an exception. Slowly, Mr. Singh began accumulating 3,500 acres in Gurgaon that he divided into plots and began selling to people unable to afford prices in New Delhi.

Mr. Singh had become the company’s India representative after befriending Jack Welch, then the G.E. chairman. When Mr. Welch decided to outsource some business operations to India, he eventually opened a G.E. office inside a corporate park in Gurgaon in 1997. “When G.E. came in,” Mr. Singh said, “others followed.”

Ordinarily, such a wild building boom would have had to hew to a local government master plan. But Gurgaon did not yet have such a plan, nor did it yet have a districtwide municipal government. Instead, Gurgaon was mostly under state control. Developers built the infrastructure inside their projects, while a state agency, the Haryana Urban Development Authority, or HUDA, was supposed to build the infrastructure binding together the city.

From computerized control rooms, Genpact employees manage 350 private drivers, who travel roughly 60,000 miles every day transporting 10,000 employees.

The city’s residential compounds, especially the luxury developments along golf courses, exist as similarly self-contained entities.

“We pretty much carry the entire weight of what you would expect many states to do,” said Pramod Bhasin, who this spring stepped down as Genpact’s chief executive. “The problem — a very big problem — is our public services are always lagging a few years behind, but sometimes a decade behind. Our planning processes sometimes exist only on paper.”

Not all of the city’s islands are affluent, either. Gurgaon has an estimated 200,000 migrant workers, the so-called floating population, who work on construction sites or as domestic help.

Meanwhile, with Gurgaon’s understaffed police force outmatched by such a rapidly growing population, some law-and-order responsibilities have been delegated to the private sector. Nearly 12,000 private security guards work in Gurgaon, and many are pressed into directing traffic on major streets.

Sudhir Rajpal, the wiry, mustachioed commissioner of the new Municipal Corporation of Gurgaon, has a long to-do list: fix the roads, the sewers, the electrical grid, the drainage, the lack of public buses, the lack of water and the lack of planning. The Municipal Corporation was formed in 2008, and Mr. Rajpal, having assumed the city’s top administrative position a few months ago, has been conducting a listening tour to convince people that government can solve their problems. It is not an easy sell.

“The drains are broken and accidents are happening,” shouted one man. “Yet no one is answerable! There are problems and problems. Whatever water we get is dirty, but we have nowhere to complain.”

“Every day some agitation is taking place,” he said, shouting above the din of traffic. “People are not satisfied.” If people should be satisfied anywhere in India, Gurgaon should be the place. Average incomes rank among the highest in the country. Property values have jumped sharply since the 1990s. Gurgaon’s malls offer many of the country’s best shops and restaurants, while the city’s most exclusive housing enclaves are among the finest in India. Yet the economic power that growth has delivered to Gurgaon has not been matched by political power. The celebrated middle class created by India’s boom has far less clout at the ballot box than the hundreds of millions of rural peasants struggling to live on $2 a day, given the far larger rural vote, and thus are courted far less by Indian politicians.

"facts are uncertain, values in dispute, stakes high and decisions urgent," that normal scientific methods of inquiry won’t work.

what happened in the developing world following the end of World War II. The colonial empires through which European governments had dominated much of the world’s land, trade, resources, and people, rapidly disintegrated.

over 700 million souls were under the control of the British Empire outside the UK in 1945, falling to 5 million by 1965, 3 million of whom were in Hong Kong.

The echo of colonialism in the postnormal is subtle.

We’ve created a global financial and manufacturing system that has come to control and concentrate the world wealth and power into the hands of a small elite.

The rising concerns about inequity--shown in Occupy Wall Street, the Arab Spring, and the rewriting of the constitution in Iceland--are an echo of the early rise of anticolonial insurgents.

We can imagine the explosion of a new generation of manufacturing, one that doesn’t rely on either armies of semi-skilled laborers or industrial regions dominated by computer-controlled factories and their supply chains and logistics networks.
