Does Fame Drive You Crazy?

    Since the 1970s, scientists have been searching for ways to link the brain with computers. Brain-computer interface (界面) (BCI) technology could help people with disabilities send commands to machines.

    Recently, two researchers, Jose Milan and Michele Tavella from the Federal Polytechnic School in Lausanne, Switzerland, demonstrated（展示）a small robotic wheelchair directed by a person's thoughts.

    In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand. He could even talk as he watched the vehicle and guided it with his thoughts.

    “Our brain has billions of nerve cells. These send signals through the spinal cord (脊髓) to the muscles to give us the ability to move. But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles,” Tavella says.  “Our system allows disabled people to communicate with external world and also to control devices.”

    The researchers designed a special cap for the user. This head cover picks up the signals from the scalp(头皮) and sends them to a computer. The computer interprets the signals and commands the motorized wheelchair. The wheelchair also has two cameras that identify objects in its path. They help the computer react to commands from the brain.

    Prof. Milan, the team leader, says scientists keep improving the computer software that interprets brain signals and turns them into simple commands. “The practical possibilities that BCI technology offers to disabled people can be grouped in two categories: communication, and controlling devices. One example is this wheelchair.”

    He says his team has set two goals. One is testing with real patients, so as to prove that this is a technology they can benefit from. And the other is to guarantee that they can use the technology over long periods of time.

    Being the head of a high school for many years, I grew tired of budget meetings, funding cuts, and many other administrative chores. I started to dream of retirement. Sitting in traffic on a weekday morning, I would find my mind wandering. I would imagine spending time with my grandchildren, quiet evenings with my wife, traveling, or rediscovering some great books. I told myself that I wouldn't sign myself up for any committees, any classes, or anything requiring a schedule.

    My first day of retirement came at last! I cooked a great breakfast for my wife and me, leisurely read the paper, cleaned a bit of the house, and wrote a few letters to friends. On the second day, I cooked breakfast, read the paper … On the third day. This is retirement? I tried to tell myself that it was just the transition, that those golden moments were right round the corner, and that I would enjoy them soon enough. But something was missing.

    A former colleague asked a favor. A group of students was going to Jamaica to work with children in the poorest neighborhoods. Would I interrupt my newly found “happiness” and return to the students, just this once? One trip. That's all. My bags were packed and by the door.

    The trip was very inspiring. I was moved not only by the poverty I saw but also by the sense of responsibility of the young people on the trip. When I returned home, I offered to work one day a week with a local youth organization. The experience was so positive that I was soon volunteering nearly full-time, working with students across North America to assist them in their voluntary work.

    Now, it seems, the tables have turned. Some days I am the teacher, other days I am the student. These young people have reawakened my commitment to social justice issues by challenging me to learn more about the situation in the world today, where people are still poor and suffer because of greed, corruption and war. Most importantly, they have given me the opportunity to continue to participate in helping to find solutions. In return, I help them do their charitable projects overseas. I've gone from running one school to helping oversee the construction of schools in twenty-one countries!

    From the health point of view we are living in a wonderful age. A large number of once fatal illnesses can now be cured by modern drugs and surgery. But though the possibility of living a long and happy life is greater than ever before, every day we witness the unbelievable killing of people on the roads. Man is opposite to the motor-car! It is a never-ending battle which man is losing. Thousands of people are killed each year and we are quietly sitting back and letting it happen.

    It has been rightly said that when a man is sitting behind a steering-wheel(方向盘), his car becomes the extension of his personality. There is no doubt that the motor-car often brings out a man's worst character. People who are normally quiet and pleasant may become unrecognizable when they are behind a steering-wheel. They are rude, ill-mannered and aggressive. All their hidden frustrations and disappointments seem to be brought to the surface by the act of driving.

    The surprising thing is that society smiles on the motorist and seems to forgive the behavior. Everything is done for his convenience. Cities and towns are made ugly by huge car parks.

    It is high time a world law were created to reduce this senseless waste of human life. With regard to driving, the laws of some countries are not strict and even the strictest are not strict enough. A law which was universally accepted could only have a beneficial effect on the accident rate. Here are a few examples of some things that might be done. The driving test should be made to a fixed standard and far more difficult than it is; all the drivers should be made to take a test every three years or so; the age at which young people are allowed to drive any vehicle should be raised to at least 21; all vehicles should be put through strict annual tests for safety. Present drinking and driving laws (where they exist) should be made much stricter. Driving speed should be limited on all roads. These measures may sound rather severe. But surely nothing should be considered difficult if it results in reducing the annual toll of human life. After all, the world is for human beings, not motor-cars.

    I'm learning to drive in Switzerland. I think it will be a good idea to learn now because I have plenty of free time and am earning a little money to pay for lessons. I never learnt when I lived in the UK, so luckily driving on the "wrong" side isn't a problem.

    However, there are a lot of rules to remember. When you see a road to your right and there are no white lines on the ground, the cars to your right have the right to go before your car and you have to stop for them. In practice, lots of people forget this and cars either wait for each other while both drivers try to remember what to do, or beep (鸣喇叭) at each other if both try to go at the same time!

    When you drive round a roundabout, you should check all your mirrors. To remember how to do this, I often count them aloud—one, two, three—then a second glance at your blind spot when you're in the roundabout. One friend came driving with me and after about an hour asked why on earth I was counting. He had passed his test so long ago, he couldn't remember ever having to check three mirrors!

    Driving still seems scary to me so I drive quite slowly. I also don't know the countryside roads very well and don't know what's coming up round the comer or over the next hill. I drive slowly so I feel safe, but my driving instructor tells me to speed up or cars will bump into me from behind or try to overtake somewhere dangerous. So driving slowly is just as dangerous as driving fast!

    I'm not a very practical person so learning to drive has been a challenge. I don't have a lot of confidence and find it quite demotivating to do something that doesn't come naturally to me. To make driving more fun and interesting, I learn in Swiss German, so my instructor gives me instructions in Swiss. This way I've tricked myself into enjoying driving and hopefully will pass the test!

Are you a moviegoer? If, like me, you're a fan of film, then there's no better place to watch something than on the big screen at the cinema. You enter the dark theatre and take your seat, ready to be entertained. But while you are absorbed in some movie magic, many others are now getting their film fixed at home.

Over the last few years, cinemas have seen a comeback. Customers have been attracted by comfortable seats, and lots of choice of things to watch. Multiplexes in particular can screen up to twenty films at the same time, suiting all different tastes. In addition, 3D and even 4D movies can give the audience an extra immersive experience. So what's not to like about a trip to the cinema?

The coronavirus pandemic has put the future of cinema under the spotlight. Some have had to close because of reduced ticket sales. In the UK, it's brought about a surge in TV watching and online streaming. It's reported that half of UK adults will keep and continue using their new streaming subscriptions.

This isn't great news for cinemas. They rely on the release of a big blockbuster to bring the crowds back, but the launch of new films, such as James Bond: No Time To Die, are being delayed. Disney has released its $200m blockbuster, Mulan, online instead of in movie theatres. John Fithian, from the National Association of Theatre Owners, told Variety magazine: This idea of waiting out the pandemic to make your movies more profitable doesn't make sense to me. There won't be as much of an industry left to play your movies in if you do that. "
