QUES: You know that friction also causes heat. Think about when you rub your hands together. It is friction that makes them warm. But why does this happen? Friction causes the molecules on rubbing surfaces to move faster. Faster moving particles have more heat energy. Heat from friction can be useful. Can you think of other places where you might find friction? Friction also lets you light a match. Heat from friction can also cause problems. It can cause a car to overheat. To reduce friction, oil is added to the engine. Oil coats the surfaces of moving parts. This coating of oil makes them slippery. When things are slippery there is less friction. Have you ever seen a sign that says, slippery when wet? This too has to do with friction. Water, like oil, can reduce friction. The wet surface may allow your shoes to slide more easily.

QUES: U.S. Secretary of State Colin Powell arrived here on Tuesday night for meetings with fellow foreign ministers aimed at solidifying a second front, in Southeast Asia, in the campaign against global terrorism. But he has had to balance that goal with longstanding concerns about human rights abuses in the region. In meetings on Tuesday in Malaysia and Singapore before touching down in this oil-producing sultanate for two days of talks with members of the Association of South East Asian Nations, Powell said he repeatedly raised the issue. "We still believe strongly in human rights, and that everything we do has to be consistent with universal standards of human rights," he said. But at a news conference in Singapore, Powell hinted that the Bush administration was ready to discuss resuming military cooperation with Indonesia, the world's most populous Muslim nation and a sometimes reluctant partner in the efforts to crack down on militant Islamic groups. The United States cut virtually all military links with Indonesia in 1999 after its forces were implicated in the violence that swept East Timor after that territory voted for independence. On Thursday, Powell and representatives of the nations of the Asian group, including Indonesia, are expected to sign a declaration promising cooperation to prevent terrorism by sharing information, blocking funds, tightening borders and making it hard to use forged travel papers. "We recognized that terrorism is a global threat and that the disturbing acts of terrorism and transnational crimes, which continue to threaten world peace and stability, must be tackled by the international community," the ministers said in a communique on Tuesday. Powell is among the representatives from 13 nations outside Southeast Asia, including China, Japan and Russia, that are taking part in the annual meeting of the group's regional forum. Terrorism dominates the agenda, though the possibility of a meeting here between Powell and his North Korean counterpart, Paek Nam Sun, has generated the most news. It would be the highest-level contact between the United States and North Korea since President Bush took office. Powell heads to Indonesia's capital, Jakarta, late on Thursday before finishing a weeklong trip through the region in the Philippines on Saturday. He said that when he arrives in Jakarta, he will have "some ideas and some initiatives" to present to President Megawati Sukarnoputri. Indonesia is already receiving $400,000 in the current fiscal year for civilian training programs and is to receive a like amount next year; and the United States expects to provide an additional $16 million this year to train police officers in counterterrorism. At the same time, the Pentagon is reviewing how to allocate another $17 million in "counterterrorism fellowships," some of which could go to Indonesia. But a senior State Department official also acknowledged that some in the administration and Congress are pushing for more direct military cooperation, which would require congressional approval. "I think they recognize the danger that we all face and I think they have been cooperating more fully with us as time goes by, and I'm quite sure that Mrs. Megawati is committed to this cause," Powell said in Singapore. He met there with Prime Minister Goh Chok Tong, who endorsed the idea of renewed military ties between the United States and Indonesia as an important step in stabilizing that country.

MY QUESTION: Who is concerned about human rights abuse in Southeast Asia?

QUES: 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.

MY QUESTION: What remains murky about the knowledge we knew during this period and how much money did each Hamberg cell member receive?

QUES: In 1990, the U.S. Custom House in New York City was renamed after Hamilton. In 1880, his son John Church Hamilton commissioned Carl Conrads to sculpt a granite statue, now located in Central Park, New York City. One statue honoring Alexander Hamilton in Chicago was mired in controversy, at least concerning the surrounding architecture. Kate Sturges Buckingham (1858-1937), of the Buckingham Fountain family, commissioned the monument. Its impetus was that Treasury Secretary Hamilton "secured the nation's financial future and made it possible for her own family to make its fortune in grain elevators and banking. Consequently, John Angel was hired to model a figurative sculpture and the Finnish architect Eliel Saarinen was to create a "colossal architectural setting" for it. The proposed 80-foot tall columned shelter was poorly received. By Ms. Buckingham's death in 1937, the sculpture's setting. location and design were uncertain. Conspiracy allegations surfaced, and the matter became mired in litigation. After the courts ordered the construction to be completed by 1953, the trustees hired architect Samuel A. Marx. The structure was completed, had structural problems, and was eventually demolished in 1993. The statue was gilded, and is still on display. A statue, by James Earle Fraser, was dedicated on May 17, 1923, on the south terrace of the Treasury Building, in Washington.
