Example Input: (CNN) -- Since the start of the financial crisis, the world's wealthiest man, investor Warren Buffett, has been front and center. Alice Schroeder says investor Warren Buffett has become a symbol of stability in American business. He's advised Sen. Barack Obama on economic policy. He urged Congress to pass the $700 billion bailout bill. He bought stakes in Goldman Sachs and General Electric. He wrote an op-ed piece in the New York Times saying he's buying stock in American companies now because he believes they will do well in the long run, citing as his rule: "Be greedy when others are fearful." Buffett's name came up in the second presidential debate when the candidates agreed he'd be a good choice for treasury secretary. His fortune was estimated at $62 billion by Forbes in March. Alice Schroeder got Buffett's cooperation in writing her new book, "The Snowball: Warren Buffett and the Business of Life" (Bantam Books). Schroeder, who worked on Wall Street as an insurance industry analyst, met Buffett 10 years ago when his company, Berkshire Hathaway, bought a big insurance company. Schroeder says she suggested he write a book about his life, and the 78-year-old Buffett turned the tables, urging her to do it instead. Schroeder estimates she spent about 2,000 hours with Buffett and interviewed 250 people for the book. Now on a tour to promote her book, Schroeder is in a unique position to speak about Buffett at a time when many media outlets are seeking his views. "I have about 300 hours of recorded interviews and the rest of the time I observed him, I watched him make decisions and talk on the phone, went through files. I got to sit in his office for weeks, I ate steaks with him," says Schroeder, who's 51. "If it ever said moo, he'll pretty much eat it. He likes his steaks bloody rare and hanging off the plate, they're so big." CNN: Why are people so interested in Warren Buffett? Schroeder: I think he's transcended business to become a national figure because of people's trust in him as a symbol of stability and a symbol of someone who knows how to manage risk and avoid catastrophe and of how to run a business on principles. CNN: Is there any realistic possibility of him taking a government position? Schroeder: No, none. What he really likes to do is run Berkshire Hathaway, and he's not going to let anything take him away from that. He's also not going to let anyone spend his day filled up with meetings or schedule his time, he's too independent. CNN: You make clear that in the 1990s tech boom, Wall Street turned away from Buffett and there was some criticism of him. Do you think that now, because of the market downturn, people will look to him more to set a standard of how the market operates? Schroeder: I think it's fair to say that throughout his career, every time there's been a bubble and it's burst, his reputation has grown. That happened in the 1960s, when the bubble burst in the 1970s, it happened again after 1987. It happened again after the savings and loan crisis. ... It happened again after the Internet bubble and it's happening now. CNN: It doesn't seem to have had a lasting effect, since we keep going back into another boom period or bubble. Schroeder: He would say that human nature doesn't change, and that fear and greed are always the two drivers of the market. And there are people who listen when he gives learnings, but that the market will always be ruled by cycles driven by fear and greed. CNN: Have you talked to him about the current market turmoil? Schroeder: Last spring, when Bear Stearns was being taken over by J.P. Morgan ... he talked about the dominoes falling, and how, if that happened, the government could face some very unpleasant choices and have to take drastic measures. With hindsight it looks really prescient. In 2002, he talked about derivatives as financial weapons of mass destruction. More recently, his observation was that there was a lot of anger and denial at first about what was going on, and that people were not quite grasping the gravity of the situation and how quickly and dramatically they needed to move. He always says, don't sell into a panic, don't let the fear and the emotions of the market change how you feel. If you own good stocks in good companies or you own an index of the markets, and you see it getting cheaper, that's a reason to be happy, not to panic and sell. ... The idea is buy low, sell high -- not buy high, sell low. He understands the factors that are burdening the country, the federal deficit, the consumer debt, the infrastructure spending that we're going to have to do, but he has a belief in American ingenuity which over the long term has enabled our country to solve problems that seemed insurmountable in the past. For example, in the 1970s, it looked like the country could not ever dig its way out of the mess. So he does have a faith in the long-term prospects of the country. CNN: Is he a gambler? Schroeder: No, he's a handicapper -- big difference. A handicapper is somebody who understands odds-making. A gambler is somebody who bets but may not even understand the odds. Warren believes in a margin of safety, he doesn't bet unless the odds are overwhelmingly in his favor. When he goes to Vegas he does not gamble, he goes to see the shows. CNN: What are his flaws? Schroeder: He is somebody who can be very tough in business and very impersonal, including with people he likes. And in personal relationships, he negotiates as if it were a business relationship . When he was putting Berkshire Hathaway together, as [his business partner] Charlie Munger puts it, he was an implacable acquirer. The book refers to him, in my words, as a great white shark, and the book describes the battle between his avarice and his higher principles. At times, his avarice won. And over his lifetime, it's been essentially a progress during which his higher principles have increasingly had the upper hand. But when he was in junior high, he was a shoplifter. He was a juvenile delinquent. He sold his sister's bicycle. It's been pretty much uphill from there, but it hasn't been a straight line. CNN: In his adult life, was there a time when his avarice won out over higher principles? Schroeder: Absolutely, he's made investments that he shouldn't have made, for example, when he invested in Salomon. He was criticizing Wall Street and saying if you want to make a lot of money, hold your nose and go to Wall Street, and at the same time he was already there. Berkshire owned $700 million of convertible preferred [stock] in a major Wall Street bank. And he was sort of mentally distancing himself from a business that he was invested in. That kind of separation is something that's very hard to maintain. And in the end, he had to become interim chairman of Salomon to rescue the firm. Psychologically, he was trying to distance himself from it because the two sides of him were at war. CNN: Is he still critical of Wall Street? Schroeder: You've got an economy in which financial intermediaries who don't add anything to the economy ... have in the past two decades stripped off huge amounts of fees, particularly buyout funds, and hedge funds and funds of funds, and he's very, very critical of the amount of fees that have been taken out. He has no problem with executive pay when it's related to performance. He thinks in most cases executives are being paid to sit in a chair whether they perform or not.  And he's pointed out that these people are not like major league baseball players, who get recruited away by other teams. When CEOs get fired and they get these golden parachutes, you don't normally see them winding up somewhere else, right? So they're getting paid these huge amounts of money as an incentive to stay and then they get paid the consolation prize when they get fired. The pay is always getting ratcheted upward, they're getting paid to incent them to stay and they're getting paid to console them when they leave, no matter what the shareholders are getting. It's not aligned with anything the shareholders get, that really bothers him. CNN: What would he say about coping with an economic downturn? Schroeder: That people should think for the long run and make their personal decisions for the long run and build a margin of safety into their lives as best they can. Think about what could go wrong. Don't assume the best-case scenario. If you've got debts, your first thought should be how to pay them off, and negotiate with creditors if you're struggling, because they'll usually be flexible. And be realistic about what you can afford, because having a financial cushion means you can sleep at night, and that's worth more than a big-screen TV.

Example Input: ISTANBUL, Turkey (CNN) -- It's a common sight in the traffic-clogged streets of Istanbul, a city that straddles two continents. Workers next to the spot where subway trains will one day emerge from the tunnel. Opening of the tunnel has been delayed by at least four years by the discovery. A taxi driver, enraged by perpetually gridlocked traffic, stepping out of his car and yelling "Maniac!" at the man driving the public bus behind him. For decades Istanbul has been growing at a breakneck speed; its population exceeding -- by some estimates -- 15 million people. Too bad traffic often moves at a snail's pace. Most residents are quick to tell visitors the city's transport system is overwhelmed. "Istanbul is a dynamically changing city, every year increasing in population," says Zeynep Buket, an engineer working with Turkey's transportation ministry. "We are in need of radical systems, and this radical system is a mass transit system." The "radical system" city planners embarked on five years ago involved construction of a new subway tunnel beneath the Bosphorus Strait, the spectacular body of water that cuts this city in two. By the year 2025, engineers predict more than one million people a day will use the tunnel to travel between Istanbul's Asian and European shores. "We will connect two continents, Asia and Europe," said Nusret Ilbay, one of the many engineers working on the $3 billion Marmaray Tunnel Project. He was standing on scaffolding, overlooking a gaping 30-meter deep hole that will one day be a subway station on the Asian side of the Bosphorus. A concrete wall is all that holds back a churning river of sea water. Watch video of the tunnel being constructed . "As you can see, some leakage on the wall face has been observed," Ilbay explained on a tour of the construction site. "In order to overcome these leakages, we have applied chemical grouting." Legend has it, thousands of years ago Jason and the Argonauts narrowly escaped death sailing up the Bosphorus in search of the mythological Golden Fleece. Today, engineers face equally daunting challenges building a tunnel beneath one of the world's busiest shipping channels, at depths of up to 55 meters, in an active earthquake zone. First they dredged a trench on the bottom of the Bosphorus. Then, using divers and undersea cameras, they submerged and buried 11 massive pre-fabricated tunnel segments, almost all of them longer than a football field. To enter the unfinished tunnel, visitors must climb down a steep staircase in a construction tower surrounded by water in the middle of the strait. During the descent, the temperature plummets and humidity rises. Construction workers toil here in the gloom of this 1.4 kilometer long tube on the bottom of the sea, their welding torches spraying showers of sparks in the darkness. One worker claimed that during the lunch break, when the machinery came to a stop, he could hear the sound of oil tanker and cargo ships' engines as they motored past in the waters overhead. As a precaution in the event of a catastrophic flood in the tunnel, engineers constructed an emergency bunker on the bottom of the sea. Stocked with food and water and equipped with a heavy water-proof door, the "emergency room" is supposed to protect survivors for up to 10 days, until they can be rescued. But, in their rush to modernize Istanbul's transport system, city planners ran into an unforeseen obstacle: history. In Yenikapi, a neighborhood of textile factories and seedy hotels where one of the main transit stations for Istanbul's new subway and commuter rail system was to be built, archaeologists discovered the lost Byzantine port of Theodosius. It was originally built at the end of the 4th century AD by Emperor Theodosius I  when Istanbul -- then known as Constantinople -- was the capital of the eastern Roman Empire. The port's harbor silted over centuries ago, and eventually disappeared beneath subsequent layers of civilization. Until its rediscovery in 2004, archaeologists said they only knew about the port from ancient books. "This was a big moment of joy and happiness for us, an unexplainable feeling," recalls Professor Zeynep Kiziltan, the acting director of Istanbul's Archaeology Museum.  Look at pictures of the excavation » . "At around one meter below sea level, we started finding the remains of ropes. As we continued [digging] a bit more, the remains of a boat surfaced." Since that discovery, armies of hundreds of laborers and archaeologists have been working in a giant pit, three shifts a day, seven days a week. The scale of the excavation is unusual in modern-day archaeology, says Cemal Pulak, an anthropologist from Texas A&M University's nautical archaeology program. Look at a map of the site . "Its mind-boggling ... it really looks like an Indiana Jones-type operation," says Pulak, who has worked as a consultant on the excavation of the lost port. The Yenikapi dig has uncovered an ancient armada: 34 Byzantine ships ranging from dating between the 7th and 11th centuries AD. In one tent, two workers carefully uncover the ancient wooden beams of a 40-meter long merchant vessel. A third man preserves the wood by keeping it moist, sprinkling the relics with water from a hose. Archaeologists have nicknamed this ship "The Titanic," because it is the largest of the Theodosius wrecks. It is believed the vessel once carried wheat from Egypt to Constantinople. Scattered around the ship are shards of pottery, animal bones, and thousand-year-old clamshells. Historians say the new discoveries include the first examples of ships being built using the beginnings of the "skeleton approach" to constructing the vessel's hull. Pulak says that marked a revolutionary change which transformed shipbuilding from "mostly an art form to a science." "The earlier methods of building depended on verbal transference of the method from master shipbuilders to apprentices," he explained. "The development of the latter method ... allowed for the speedy communication of new shipbuilding ideas that could be transmitted on paper. It is the beginning of engineering. Ships could be preconceived and pre-designed." "I think it is one of the unique projects not only for us but for the world," said geologist Yucel Yilmaz. In addition to finding the timbers of thousand-year-old jetties and docks, which still jut up in straight rows at the bottom of the mammoth pit, archaeologists have uncovered the remnants of a pre-historic human settlement. "The first man, about 8,400 years ago, came and started to settle here," Yilmaz said. "There was no Bosphorus [then]. The Bosphorus was a river valley... the people who settled here walked across the Bosphorus." Plans to travel beneath the Bosphorus have been delayed at least four years by the excavation of the Theodosious Port. The postponement has added untold millions of dollars have also been added to the cost of the entire project. In the rush to move forward, the residents of Istanbul have accidentally uncovered a valuable piece of their city's ancient past.

Example Input: (CNN) -- New York eighth-grader Arvind Mahankali is the fiercest speller around. No word can foil him, as he proved Thursday when he beat out other Scripps National Spelling Bee contestants by spelling "knaidel" correctly. "I know this. I got this," he told CNN's "Early Start" on Friday morning, recalling how he confidently steadied himself before enunciating every letter in the Yiddish word of German origin meaning dumpling. When he uttered the final letter, the audience erupted in wild applause. The 13-year-old is feeling good even though he knows he won't be able to compete again since there's a limit on contestants beyond the eighth-grade. Mahankali isn't the type of kid who stops at spelling domination. "Next year I'll try to go somewhere in the Math Olympiad and the Physics Olympiad," he said. The Bayside Hills, New York, teen, who wants to become a physicist, finished third in two previous national bees. He was eliminated after misspelling words with German roots. "I thought that the German curse had turned into a German blessing," he said. It didn't hurt that he studied constantly, telling CNN that he browsed through the dictionary and let his mother quiz him. "My dad collects words. I look up those words and get familiarity with those words." Ending his Scripps career with a victory means he's "retiring on a good note," he said. "I shall spend the summer," he said, "maybe (an) entire day, studying physics." Pranav Sivakumar, a 13-year-old from Tower Lakes, Illinois, finished second. He missed on "cyanophycean." Then Mahankali nailed "tokonoma" and "knaidel," and the rest is history. The annual contest offers the winner a healthy dose of classroom cred, $32,500 in cash and savings bonds, a trophy and a library of reference materials. Contest isn't bee-all and end-all . Eleven million schoolchildren participated in preliminaries leading up to the national contest this week. Of those, 281 children made the trip to Oxon Hill, Maryland, outside Washington, for the national bee. Eleven spellers made it through to the finals. Among them were 63 children who had been to at least one national bee before, and had to prepare for some changes in the rules for this year's events. For the first time, participants had to demonstrate proficiency in vocabulary in addition to spelling. Organizers also added an additional computer test for the semifinals, imposed time limits on computer-based spelling and vocabulary tests, and added a rule that resulted in automatic elimination for any participant who misspelled a word on stage in the second or third rounds. CNN's Athena Jones and Michael Pearson contributed to this report.
