QUES: 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?

MY QUESTION: How do magnets work to keep a maglev train moving?

QUES: Fossils can be used to match up rock layers. As organisms change over time, they look different. Older fossils will look different than younger fossils. Some organisms only survived for a short time before going extinct. Knowing what organisms looked like at certain times also helps date rock layers. Some fossils are better than others for this use. The fossils that are very distinct at certain times of Earths history are called index fossils. Index fossils are commonly used to match rock layers. You can see how this works in Figure 2.30. If two rock layers have the same index fossils, then they're probably about the same age.

QUES: The Domestic Violence Legal Assistance Program fills the gap of legal resources for domestic violence survivors who can't afford an attorney. Domestic violence survivors in Jackson, Vicksburg, Hattiesburg, Oxford and Pascagoula can all get help. Julia Crockett, deputy director of Central Southwest Mississippi Legal Services Corp., said the program expects to help nearly 1,000 domestic violence victims. Crockett said legal help gives domestic abuse survivors a way to rebuild their lives. "They have been made to feel by the abuser that no one is going to help them do anything, so when they come to us they are desperate," she said. "Those who need legal help and don't get it feel totally lost. Because then they feel like they are forced to stay in that situation." Crockett said the program, funded by a $300,000 grant from the U.S. Justice Department, has no economic restrictions on who can get help. Legal services typically helps the poor. Gladys Bunzy, who said she was in an abusive relationship with a boyfriend for eight years, said such a program is long overdue and could be a lifeline for those escaping violent relationships. "When I finally made up my mind to leave, I had a restraining order put against him and that was $50 but that was $50 well spent to me," said Bunzy, 40. "For people who can't afford it, this will be a godsend ... If a woman knows she is going to get some help that will be a burden off her mind, if the law will help her keep that person away from her." Gwen Bouie-Haynes, project director of the Domestic Violence Services Center for Catholic Charities Inc., said often domestic violence survivors do not have the money to seek legal representation. "Legal assistance is a major issue for women fleeing a domestic violence situation," she said. "Often times women are in need of immediate legal assistance services for the protection of the mother and the child. To get a protective order you need to be represented by an attorney." Crockett said the pilot program was launched in 1998 at the Haven House Family Shelter Inc., a domestic violence shelter for women and children in Vicksburg. The program has helped victims in 90 court cases, and 150 legal counseling sessions have been held there.

QUES: At 8:38, Ong told Gonzalez that the plane was flying erratically again. Around this time Sweeney told Woodward that the hijackers were Middle Easterners, naming three of their seat numbers. One spoke very little English and one spoke excellent English. The hijackers had gained entry to the cockpit, and she did not know how. The aircraft was in a rapid descent. At 8:41, Sweeney told Woodward that passengers in coach were under the impression that there was a routine medical emergency in first class. Other flight attendants were busy at duties such as getting medical supplies while Ong and Sweeney were reporting the events. At 8:41, in American's operations center, a colleague told Marquis that the air traffic controllers declared Flight 11 a hijacking and "think he's [American 11] headed toward Kennedy [airport in New York City]. They're moving everybody out of the way. They seem to have him on a primary radar. They seem to think that he is descending." At 8:44, Gonzalez reported losing phone contact with Ong. About this same time Sweeney reported to Woodward, "Something is wrong. We are in a rapid descent . we are all over the place." Woodward asked Sweeney to look out the window to see if she could determine where they were.
