The most frightening words in the English language are, “Our computer is down.” You hear it more and more when you are on business. The other day I was at the airport waiting for a ticket to Washington and the girl in the ticket office said, “I'm sorry, I can't sell you a ticket. Our computer is down.”

    “If your computer is down, just write me out a ticket.”

    “I can't write you out a ticket. The computer is the only one allowed to do so.”

    I looked down on the computer and every passenger was just standing there drinking coffee and staring at the black screen. Then I asked her, “What do all your people do?”

    “We give the computer the information about your trip, and then it tells us whether you can fly with us or not.”

    “So when it goes down, you go down with it.”

    “That's good, sir.”

    “How long will the computer be down?” I wanted to know.

    “I have no idea. Sometimes it's down for 10 minutes, sometimes for two hours. There's no way we can find out without asking the computer, and since it's down it won't answer us.”

    After the girl told me they had no backup(备用) computer, I said. “Let's forget the computer. What about your planes? They're still flying, aren't they?”

    “I couldn't tell without asking the computer.”

    “Maybe I could just go to the gate and ask the pilot if he's flying to Washington, ” I suggested.

    “I wouldn't know what gate to send you to. Even if the pilot was going to Washington, he couldn't't take you if you didn't't have a ticket.”

    “Is there any other airline flying to Washington within the next few hours?”

    “I wouldn't know,” she said, pointing at the dark screen. “Only 'IT' knows. 'IT' can't tell me.

    By this time there were quite a few people standing in lines. The word soon spread to other travelers that the computer was down. Some people went white, some people started to cry and still others kicked their luggage.

    From July to October every year, about a quarter of the world's blue whales feed in the Pacific Ocean off the coast of California. But the whales currently face a major threat in their favorite feeding area. Ships carrying cargo (货物）sail in the same area at the same time. All too often, the whales' paths and the ships' travel lines overlap (重叠), and a ship will hit a whale.

    According to a new study, these ship strikes have become a serious threat to the overall population of the world's blue whales. Only about 10,000 of the creatures still exist worldwide. Blue whales are the largest known animals ever to live on Earth. Even so, if hit by a container ship, a blue whale will likely die from its injuries.

    In 2007 alone, large ships killed five blue whales in the waters off San Francisco and Los Angeles, California. The National Oceanic and Atmospheric Administration (NOAA) says that because there are so few whales already, losing three to five from the California whale population every year is a significant loss. “The estimated population of blue whales in this part of the Pacific is 2,500”, says Sean Hastings, a NOAA analyst. “So every whale counts toward this species moving off the endangered-species list.”

    Now, marine scientists must figure out how to protect the whales from the giant container ships. One very simple program is already under way in the Santa Barbara Channel, a waterway that separates mainland California from the nearby Channel Islands.

    The Channel Islands National Marine Sanctuary has asked large container ships passing through the area to voluntarily slow down. Sailing slower will allow the ships‟ crew (船员）more time to change course before hitting a whale.

    Several of the world's largest shipping lines are set to participate in the new program. For every ship that passes through the Santa Barbara Channel at or below the reduced speed of 12 knots (海里/小时）, the company that owns the ship will be paid $2,500.

    Actually, long-distance bicycle camping is one of the most pleasurable activities I have ever experienced.

    I generally sleep poorly at night, but in the woods on a tour, I sleep like a baby, falling asleep with the music of insects. In the morning, I am awakened by the cheeps of birds. I eat a snack before getting up, and then I quickly pack my sleeping bag, air mattress (垫), tent, and other things and get on with my road. I'm slower in the morning, having less speed but a greater desire to stop at pleasant spots and enjoy the beautiful scenery. Traveling by bike allows me to stop anywhere, such as grasslands, lakes, woods, and scenic spots. Near lunch, I find a small grocery and buy some bread, sandwiches and fruit. Then I will find a town park or other shady spots to wait out the high mid-day sun. In the afternoon, my speeds are higher, and I spend less time on stops. In the late afternoon, I start riding more slowly, and I start thinking about where I will stop. I finally find a place in the early evening, cook a simple meal and have a rest. As it starts to get dark, I put up my tent, crawl in and fall asleep.

    There are exciting times and difficult times as well. Visiting strange or famous places and accomplishing goals are always exciting to me. I meet and talk with interesting people along the way, sometimes other traveling cyclists. Appreciating beautiful views, meeting wild animals, and traveling up and down hills also. On the other hand, I may run into a rainy or hot spell(一段时间), have to repair my bike, or just find myself in a bad mood. The problems are infrequent and are easy to deal with. The pleasures remain in my mind for years.

    The year 2117 will be an eventful one for art. In May of that year in Berlin, the philosopher-artist Jonathon Keats' “century cameras”— cameras with a 100-year-long exposure (曝光)time—will be brought back from hiding places around the city to have their results developed and exhibited. Six months after that, the Future Library in Oslo, Norway, will open its doors for the first time, presenting 100 books printed on the wood of trees planted in the distant past of 2017.

    As Katie Paterson, the creator of the Future Library, puts it: “Future Library is an artwork for future generations.” These projects, more than a century in the making, are part of a new wave of slow art intended to push viewers and Participants to think beyond their own lifetimes. They aim to challenge today's short-term thinking and the brief attention spans of modern consumers, forcing people into considering works more deliberately. In their way, too, they are fighting against modern culture—not just regarding money, but also the way in which artistic worth is measured by attention.

    In a similar fashion, every April on Slow Art Day, visitors are encouraged to stare at five works of art for 10 minutes at a time—a tough task for the average museum visitor, who typically spends less than30seconds on each piece of art.

Like the Future Library, the century cameras are very much a project for cities, since it's in cities that time runs fastest and the pace of life is fastest. “Since I started living in a city, I've somehow been quite disconnected,” Anne Beate Hovind, the Future Library project manager, who described how working on the library drew her back to the Pace of life she knew when she was growing up on a farm in her youth, told The Atlantic magazine.

    Steven Spielberg's 2002 science-fiction thriller Minority Report produced a world where computers could read minds and predict the future. It seemed fanciful at the time, but fantasy is edging closer to fact.

    On Jan 31, a team of scientists at UC Berkeley, led by Robert Knight programmed computers to decode (破译) brain waves and replay them as words. Five months earlier, another group of Berkeley scientists showed their colleagues short movies and used computers to play back in color what people saw.

    These experiments are a big advance from 2006, when a French scientist first replayed images from a human mind, a black-and-white checkerboard pattern. The possibilities are great: a disabled person could" speak"; doctors could access the mind of a patient who fainted; you could rewatch your dreams on an iPad. There are, of course, equally dark side, such as the involuntary take out of information from the brain.

    In spite of these breakthroughs, Jack Gallant, the neuroscientist who led the first Berkeley team, says current technology for decoding brain activity is still "relatively primitive". The field is held back by its poor machinery, in particular the FMRI.

    "Eventually," says Gallant, "someone will invent a decoding machine you can wear as a hat." Such an advance into the human mind, he says, might take 30 years.

    Still, the recent advances at Berkeley offer small answers, which scientists can use to begin unlocking the secrets of memory and consciousness.

    Being deaf in a hearing world can lead to painful feelings of isolation (孤独).

    Waitress Kelsey recently shared an experience on a social media sharing site that quickly zoomed (陡直上升) to the top of the" front page of the Internet". In her brief post, Kelsey explained that she waits tables at a bar during the evenings, and one night she noticed a deaf man sitting alone in her section (区域).

    When Kelsey isn't working at the bar she makes a good hourly pay doing sign language interpretation (翻译), so she sensed an opportunity to use her skill to make this customer feel a little less alone in the world. She approached his table and began chatting with him in sign language.

    When the table next to his noticed their silent conversation they asked Kelsey how long she'd been signing. They had a brief conversation about her goal of becoming certified (合格的) to interpret sign language in a medical or mental health setting. She didn't think much about the whole exchange until the customers had left the restaurant and she was tidying up the tables. There, on the table of the customers who'd seen her American sign language conversation with the deaf man, was a handwritten note on the receipt.

    "Thank you for what you do; it absolutely matters!" the note said. "Good luck with finishing your degree!" Not only that, but they'd left her a $100 tip.

    Kelsey was moved by the kind note, especially because she wasn't doing anything out of the ordinary. To her, she was just conversing with someone in a language that only they understood. Yet to the deaf man and the people seated next to him she'd bridged a gap and helped someone who probably feels lonely a lot of the time.

    Kelsey shared the note on the Internet to spread more love and light in the world.
