Take a look at this train in Figure 1.11. It looks very futuristic. What do you notice about it? Did you notice that the train has no wheels? How can a train have no wheels? It doesn't need wheels. It actually floats, or levitates, just above the track. Magnets enable the train to do this. This is not a normal train. This is a maglev train. The word maglev stands for magnetic levitation. Because it has no wheels, there is no friction. Some magnets hold the train up. Other magnets are used to move the train forward. This train can go very fast. It can reach speeds up to 480 kilometers (300 miles) per hour! Magnets are pretty cool. What exactly is a magnet? How is it able to exert such force?

The 1933 double eagle, a $20 gold piece with a mysterious history that involves a president, a king and a Secret Service sting operation, was auctioned Tuesday last night for a record price for a coin, $7.59 million, nearly double the previous record. The anonymous buyer, believed to be an individual collector who lives in the United States, made the winning bid in a fiercely contested nine-minute auction at Sotheby's in Manhattan. Eight bidders were joined by 500 coin collectors and dealers in an auction house audience seemingly devoid of celebrity bidders, while an additional 534 observers followed the bidding on eBay. As auction houses prepare for their fall seasons in an uncertain economy, the sale price "suggests that the marketplace for important items is enormously strong," said David Redden, a vice chairman at Sotheby's, who was the auctioneer. "This is an astonishing new record for a coin," he said. In an unprecedented move, the auction proceeds were split by the U.S. Mint and a London coin dealer, Stephen Fenton, who had won that right in court after having been arrested by Secret Service agents for trying to sell the coin in the Waldorf-Astoria Hotel in Manhattan in 1996. Henrietta Holsman Fore, the director of the U.S. Mint, who witnessed the sale, said, "The monies we receive will go toward helping to pay down the debt and to fight the war on terrorism." Fenton commented that the double eagle had been on "a long historic journey, with a very satisfying ending." He added, "I am thrilled with the price." The previous numismatic record holder was an 1804 U.S. silver dollar, which sold for $4.14 million in 1999. Sotheby's partner in the one-lot auction was Stack's Rare Coins, with which it shared the customary 15 percent commission. "I have never seen as much interest in the sale of any coin in my 30 years in the business," said Lawrence R. Stack, the company's managing director. "This is the Mona Lisa of coins," said Beth Deisher, editor of Coin World, the largest weekly coin publication in the United States, with a circulation of 85,000. "It is unique. Forbidden fruit." Collectors' Web sites have surged with speculation about the sale price, and enthusiasts even organized betting pools.

Problem: Bin Laden and his aides did not need a very large sum to finance their planned attack on America. The 9/11 plotters eventually spent somewhere between $400,000 and $500,000 to plan and conduct their attack. Consistent with the importance of the project, al Qaeda funded the plotters. KSM provided his operatives with nearly all the money they needed to travel to the United States, train, and live. The plotters' tradecraft was not especially sophisticated, but it was good enough. They moved, stored, and spent their money in ordinary ways, easily defeating the detection mechanisms in place at the time. The origin of the funds remains unknown, although we have a general idea of how al Qaeda financed itself during the period leading up to 9/11. General Financing As we explained in chapter 2, Bin Laden did not fund al Qaeda through a personal fortune and a network of businesses in Sudan. Instead, al Qaeda relied primarily on a fund-raising network developed over time. The CIA now estimates that it cost al Qaeda about $30 million per year to sustain its activities before 9/11 and that this money was raised almost entirely through donations. For many years, the United States thought Bin Laden financed al Qaeda's expenses through a vast personal inheritance. Bin Laden purportedly inherited approximately $300 million when his father died, and was rumored to have had access to these funds to wage jihad while in Sudan and Afghanistan and to secure his leadership position in al Qaeda. In early 2000, the U.S. government discovered a different reality: roughly from 1970 through 1994, Bin Laden received about $1 million per year-a significant sum, to be sure, but not a $300 million fortune that could be used to fund jihad. Then, as part of a Saudi government crackdown early in the 1990s, the Bin Laden family was forced to find a buyer for Usama's share of the family company in 1994. The Saudi government subsequently froze the proceeds of the sale. This action had the effect of divesting Bin Laden of what otherwise might indeed have been a large fortune. Nor were Bin Laden's assets in Sudan a source of money for al Qaeda. When Bin Laden lived in Sudan from 1991 to 1996, he owned a number of businesses and other assets.
