Surely, you have noticed the tall poles along the roadside. Do you know what is on top of those poles? Thats right, wires that carry electric current. These wires carry electric current to your home. But what is electric current? Electric current is actually the flow of electrons. You may recall, an electron is the outer-most particle in an atom. They have a negative charge. Electricity is the continuous flow of these particles. Electrons are able to move through wires. Their speed can even be measured. The SI unit for electric current (or speed) is the ampere (A). Ampere is often shortened to amp. Electric current may flow in just one direction, or it may keep reversing direction. Direct current (DC) flows in only one direction. Direct current is what is used in devices like flashlights. Alternating current (AC) flows in two directions. This is the type of current that flows into your home through wires.

Fact: I wasn't dead. After I realized this, I left my quarters. The lightscreen provided had informed me when and where official meals were taking place, but I hadn't bothered to acknowledge the invitations. It hadn't seemed relevant, somehow, given that I was still reeling over the explosion, the deaths of my crewmates, and the rescue. I've heard there are a number of stages of grief and shock; I guess I was working my way through them. Food was delivered to my quarters. Initially, I couldn't figure out whyI hadn't requested any be sent. Then I realized, someone must have noticed I hadn't left, and was nice enough to send food my way. The accompanying bottle of wine was a nice touch. I must have consumed it, too, because later on, the plates and the bottle were both empty. I spent a lot of time lying on my back on the bed, staring up at the little etched swirls in the ceiling, or slumped in the old-fashioned armchair, staring out the windows at the stars. I did a lot of staring and not moving. Man, was it good to be done with that stage. It was time to find out what hell looked like.

In the popular mind, the history of Hong Kong, long the entryway to China for Westerners, begins in 1841 with the British occupation of the territory. However, it would be wrong to dismiss the long history of the region itself. Archaeologists today are working to uncover Hong Kong's past, which stretches back thousands of years. You can get a glimpse into that past at Lei Cheng Uk Museum's 1,600-year-old burial vault on the mainland just north of Kowloon. In 1992, when construction of the airport on Chek Lap Kok was begun, a 2,000-year-old village, Pak Mong, was discovered, complete with artifacts that indicated a sophisticated rural society. An even older Stone Age site was discovered on Lamma Island in 1996. While Hong Kong remained a relative backwater in early days, nearby Guangzhou (Canton) was developing into a great trading city with connections in India and the Middle East. By a.d. 900, the Hong Kong islands had become a lair for pirates preying on the shipping in the Pearl River Delta and causing a major headache for burgeoning Guangzhou; small bands of pirates were still operating into the early years of the 20th century. In the meantime, the mainland area was being settled by incomers, the "Five Great Clans": Tang, Hau, Pang, Liu, and Man. First to arrive was the Tang clan, which established a number of walled villages in the New Territories that still exist today. You can visit Kat Hing Wai and Lo Wai, villages with their walls still intact. Adjacent to Lo Wai is the Tang Chung Ling Ancestral Hall, built in the 16th century, which is still the center of clan activities. The first Europeans to arrive in the Pearl River Delta were the Portuguese, who settled in Macau in 1557 and for several centuries had a monopoly on trade between Asia, Europe, and South America. As Macau developed into the greatest port in the East, it also became a base for Jesuit missionaries; it was later a haven for persecuted Japanese Christians. While Christianity was not a great success in China, it made local headway, evidenced today by the numerous Catholic churches in Macau's historic center. Intermarriage with the local Chinese created a community of Macanese, whose culture can still be seen in Macau's architecture and cuisine.

The old vaulted church was stripped down: there was no cloth on the altar, just a DJ's toolkit and his beer. Through the dark, I could see three bolts left in the wall from where they'd taken down the crucifix. A confessional too beaten-up to have been sold was shaking in a way that suggested activity inside, and where the pews had been taken out, a couple hundred people were testifying to the DJ's moving sermon. Rachel stepped forward into the crowd while I took a moment to drink in the ceiling's blue-lit, shadowed vault and the light-catching haze from who-knows-what rising between the DJ and the crowd. There was a terrific echo, each beat reverberating inside of the next, and the old stained-glass windows rattled in their frames. On the dance floor, people moved with their eyes closed and their hands in the air. I danced with Rachel for a while, but then something by the bar seemed to be pulling her eyes. She told me that she was heading for a drink and slipped out of the crowd. When she hadn't come back halfway through the next song, I glanced over at the bar. It was just a little set-up where someone had stacked a few crates and brought something alcoholic to share, mostly beer. Rachel was standing with a plastic cup, looking like she was having a conversation, but I couldn't see anyone else there. The next time the crowd split, I saw him. He stood in front of a blue light, so I couldn't see him clearly, but what I saw was memorable. He wore a jacket of what might have been blue velvet, and his hair gleamed black against his white skin. The blue haze seemed to stop just shy of his pallor, setting off his striking face without illuminating its details, and his wrists flashed white in the darkness. He didn't move, just stared and held his drink. The next time I saw them, his mouth was moving. She nodded and he took her arm. I watched them through the crush of dancers as they squeezed along the wall, and the feeling came to me that something was very wrong. Saturday morning, I woke up and saw that she still hadn't come home.
