Magnets are able to place a force on certain materials. This force is called a magnetic force. The force a magnet exerts is a little different from the forces you may normally think about. You exert a force on a book when you lift it. You also exert a force on the pedals of your bicycle. In both those cases, those forces cause a change. The change you see in both these cases is called motion. Magnets, too, can produce change. They can produce motion just like you do. Unlike you, magnets do not have to touch something to exert a force. A magnetic force is exerted over a distance. Thats right, a magnet can push or pull certain items without ever touching them. Thats how the maglev train works. Do you know another type of force that does not require objects to touch? These forces are known as non-contact forces. Another type of non-contact force you may be familiar with is gravity. Gravity too can cause changes in motion. Gravity holds our moon in orbit without touching it.

The force that holds our moon in place, is an example of what type of force?

Reuters Holdings PLC said Michael Reupke resigned as general manager to pursue unspecified interests, a move the news organization termed an "amicable separation." Mr. Reupke, 52 years old and a 27-year Reuters veteran, had been the information-services company's general manager for only six months. His appointment to that post, which has senior administrative, staff and policy responsibilities, followed a several-year tenure as Reuters's editor in chief. No successor was named, and Mr. Reupke's duties will be split among three other senior Reuters executives, the company said. In a telephone interview, Mr. Reupke said his departure was for "personal reasons," which he declined to specify. "There is no business reason for my departure," nor any disagreement over policy, he added. He also rejected reports that his departure stemmed from disappointment the general manager's post hadn't also led to a board directorship at the London-based news organization. Mr. Reupke was one of three executives on Reuters's eight-person executive committee who didn't also serve on the company's board of directors. "If I were choosing the people of tomorrow, I would have chosen the people who are now on the board," he said. A Reuters spokesman said the departure reflects "no change in strategy or profits." Mark Shepperd, an analyst at UBS Philips & Drew in London, said, "I suspect (the departure) will be fairly irrelevant for the company. I would be very surprised if his departure signals any change in strategy or change in profit expectations." On London's Stock Exchange, Reuters shares rose five pence to 913 pence ($14.43). In the U.S. over-the-counter market, American depositary shares for Reuters, each representing three shares in the London market, closed unchanged at $43.875. The senior of the three executives who will assume Mr. Reupke's duties is Nigel Judah, 58, finance director and a Reuters board director. Peter Holland, 45, deputy general manager, becomes director of corporate affairs. And Patrick Mannix, 46, international technical manager, becomes director of group quality programs.

Who is the successor named following Michael Reupke's resignation?

As noted above, the 9/11 plotters spent somewhere between $400,000 and $500,000 to plan and conduct their attack. The available evidence indicates that the 19 operatives were funded by al Qaeda, either through wire transfers or cash provided by KSM, which they carried into the United States or deposited in foreign accounts and accessed from this country. Our investigation has uncovered no credible evidence that any person in the United States gave the hijackers substantial financial assistance. Similarly, we have seen no evidence that any foreign government-or foreign government official-supplied any funding. We have found no evidence that the Hamburg cell members (Atta, Shehhi, Jarrah, and Binalshibh) received funds from al Qaeda before late 1999. It appears they supported themselves. KSM, Binalshibh, and another plot facilitator, Mustafa al Hawsawi, each received money, in some cases perhaps as much as $10,000, to perform their roles in the plot. After the Hamburg recruits joined the 9/11 conspiracy, al Qaeda began giving them money. Our knowledge of the funding during this period, before the operatives entered the United States, remains murky. According to KSM, the Hamburg cell members each received $5,000 to pay for their return to Germany from Afghanistan after they had been selected to join the plot, and they received additional funds for travel from Germany to the United States. Financial transactions of the plotters are discussed in more detail in chapter 7. Requirements for a Successful Attack As some of the core operatives prepared to leave for the United States, al Qaeda's leaders could have reflected on what they needed to be able to do in order to organize and conduct a complex international terrorist operation to inflict catastrophic harm. We believe such a list of requirements would have included leaders able to evaluate, approve, and supervise the planning and direction of the operation; communications sufficient to enable planning and direction of the operatives and those who would be helping them; a personnel system that could recruit candidates, vet them, indoctrinate them, and give them necessary training; an intelligence effort to gather required information and form assessments of enemy strengths and weaknesses; the ability to move people; and the ability to raise and move the necessary money. The information we have presented about the development of the planes operation shows how, by the spring and summer of 2000, al Qaeda was able to meet these requirements. By late May 2000, two operatives assigned to the planes operation were already in the United States. Three of the four Hamburg cell members would soon arrive.
Where did money to fund the 9/11 plotters come from and where didn't it come from?
