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?

It would allow me to leave this bed, despite my current illness. My problem is that it was not made in this realm, but by a human, and only a human may handle it. The herb vendor will tell you where you can find it. If you would fetch me this stone, I would tell you what I can." "Of course we will fetch you the stone," Nepthys assured him. "You have our thanks." Outside, the thing at the herb cart nodded when we mentioned the stone. He told Nepthys the name of a woman who lived on a certain street, and we set off.

Instead, it looked like we were in the red-light district: women who probably wanted more than our money eyed us from the alleys. Nepthys didn't need to warn me not to speak to them. He took us to the door of a building like a short pagoda that had a sign hanging over it showing a face with hands uplifted, like a saint under G d's light, and handcuffed. Inside, the entrance room was hung with bright silks and scattered with velvet cushions. Sails of obscene orange and a green that insulted springtime hung draped across reds that might have been sensual elsewhere but here were only offensive. A large woman, similarly decorated, quickly drifted up to us. "Good evening, gentlemen," she said. "May I invite you to have a cup of tea?" "No, thank you," said Nepthys, "we regret that we cannot take up your kind offer. Are you the proprietor of this shop?" "Yes," answered the woman. "I am Madame Entera, at your service.
