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?

After becoming disabled in a machete attack on a visit to his native Haiti, Jean-Claude Joseph needed help persuading his landlord to move him from a fifth-floor apartment to one on the ground floor. Isaac Benjamin became ensnared in a bureaucratic snafu that took away his Social Security disability payments for more than two years. The story of Martha, a woman from Sierra Leone, was more compelling. Beaten, raped and tortured in her politically repressive homeland, she knowingly used someone else's passport to escape to America, but was caught by immigration authorities upon her arrival. She desperately sought political asylum. Not the kind of cases that lead to ground-breaking upheavals in the law, but the kind of cases that are handled day in and day out by lawyers for the legally disenfranchised who have no where else to turn. The work of attorneys from Legal Services of New Jersey will be highlighted in a onehour documentary, "Quest for Justice," to be aired 9 p.m. today on New Jersey Network. Produced by NYD2, a communications firm based in Somerset, the documentary features case histories of clients whose needs ranged from housing to fighting off deportation. Joseph, a 54-year-old naturalized citizen, turned to Legal Services when the landlord of his federally subsidized apartment complex in Elizabeth turned a deaf ear to his request for a ground-floor apartment. Having lost the use of his left arm in warding off the machete attack during a robbery attempt, Joseph said he found it increasingly difficult to negotiate the five flights of stairs lugging groceries or laundry on the frequent occasions when the building's elevator was out of order. "With this, it became impossible for me to stay upstairs," he said, pointing to the scars on his forearm. "If I cannot carry my groceries or my laundry, how can I live?" "It was a compelling case," said Legal Services attorney Stephen St. Hilaire. "The key for us -- and we have to make tough decisions all the time on whether to take a case -- was visualizing what he had to do to get to the fifth floor, struggling with a bag of groceries," he said. Benjamin, 53, of Jersey City had been collecting Social Security disability after undergoing double bypass surgery when the checks stopped coming. He said the agency claimed he had failed to return a form updating the condition of his health. "But what got me was they didn't let me know they didn't get it, they just cut me off," he said, adding he found it impossible to negotiate the Social Security bureaucracy himself.

The Reconquest: The aim of the Crusades in Spain was the eviction of the Muslims. After the recovery of Jerusalem in 1099, it took four hundred years of sieges and battles, treaties, betrayals, and yet more battles, before Christian kings and warlords succeeded in subduing the Moors. On 10 September 1229, a Catalan army led by King Jaume I of Aragon and Catalunya took the Mallorcan shore near the present-day resort of Santa Ponca. The defenders retreated inside the walls of Palma, but on the last day of 1229 the city fell, and pockets of resistance throughout the island were also defeated. Jaume I proved to be an enlightened ruler who profited from the talents of the Moorsconverted by force to Christianityas well as of the island's large Jewish and Genoese trading communities. Mallorca prospered. The Moors on Menorca speedily agreed to pay an annual tribute to Aragon and were left in peace. The island's tranquility lasted until 1287, when Alfonso III of Aragon, smarting over a series of humiliations at the hands of his nobles, found a pretext for invasion. The Moors were defeated and expelled or killed. In contrast to Mallorca, Menorca's economy was devastated for decades. Jaume I died after reigning in Aragon for six decades, but he made the cardinal error of dividing between his sons the lands he had fought for so long to unite. At first this resulted in an Independent Kingdom of Mallorca, under Jaume II, followed by Sanc and Jaume III. But family rivalry triggered the overthrow of Jaume III by his cousin Pedro IV, who then seized the Balearics for Aragon. Attempting a comeback, Jaume was killed in battle near Llucmajor in 1349. A newly unified Christian Spain under the Catholic Monarchs, Ferdinand and Isabella, completed the Reconquest, defeating the only Moorish enclave left on the Iberian peninsula, Granada, in 1492. However, the centralized kingdom failed to incorporate the Balearics politically or economically.

When Alexander destroyed Tyre, most of the towns on the route to Egypt quickly capitulated. A later tradition recorded his entry into Jerusalem: according to Josephus, Alexander was shown the Book of Daniel's prophecy, presumably chapter 8, which described a mighty Greek king who would conquer the Persian Empire. He spared Jerusalem and pushed south into Egypt. However, Alexander met with resistance at Gaza. The stronghold was heavily fortified and built on a hill, requiring a siege. When "his engineers pointed out to him that because of the height of the mound it would be impossible... this encouraged Alexander all the more to make the attempt". After three unsuccessful assaults, the stronghold fell, but not before Alexander had received a serious shoulder wound. As in Tyre, men of military age were put to the sword and the women and children were sold into slavery. Alexander advanced on Egypt in later 332 BC, where he was regarded as a liberator. He was pronounced son of the deity Amun at the Oracle of Siwa Oasis in the Libyan desert. Henceforth, Alexander often referred to Zeus-Ammon as his true father, and after his death, currency depicted him adorned with rams horn as a symbol of his divinity. During his stay in Egypt, he founded Alexandria-by-Egypt, which would become the prosperous capital of the Ptolemaic Kingdom after his death.
