    This month, Germany's transport minister, Alexander Dobrindt, proposed the first set of rules for autonomous vehicles(自主驾驶车辆). They would define the driver's role in such cars and govern how such cars perform in crashes where lives might be lost.

    The proposal attempts to deal with what some call the “death valley” of autonomous vehicles: the grey area between semi-autonomous and fully driverless cars that could delay the driverless future.

    Dobrindt wants three things: that a car always chooses property(财产) damage over personal injury; that it never distinguishes between humans based on age or race; and that if a human removes his or her hands from the driving wheel — to check email, say — the car's maker is responsible if there is a crash.

    “The change to the road traffic law will permit fully automatic driving,” says Dobrindt. It will put fully driverless cars on an equal legal footing to human drivers, he says.

    Who is responsible for the operation of such vehicles is not clear among car makers, consumers and lawyers. “The liability(法律责任) issue is the biggest one of them all,” says Natasha Merat at the University of Leeds, UK.

    An assumption behind UK insurance for driverless cars, introduced earlier this year, insists that a human “ be watchful and monitoring the road” at every moment.

    But that is not what many people have in mind when thinking of driverless cars. “When you say ‘driverless cars', people expect driverless cars.”Merat says. “You know — no driver.”

    Because of the confusion, Merat thinks some car makers will wait until vehicles can be fully automated without operation.

    Driverless cars may end up being a form of public transport rather than vehicles you own, says Ryan Calo at Stanford University, California. That is happening in the UK and Singapore, where government-provided driverless vehicles are being launched.

    That would go down poorly in the US, however. “The idea that the government would take over driverless cars and treat them as a public good would get absolutely nowhere here,” says Calo.

    Tim Richter and his wife, Linda, had taught for over 30 years near Buffalo, New York—he in computers, she in special education. “Teaching means everything to us,” Tim would say. In April 1998, he learned he would need a heart operation. It was the kind of news that leads to some serious thinking about life's purpose.

    Not long after the surgery, Tim saw a brochure describing Imagination Library, a program started by Dolly Parton's foundation (基金会) that mailed a book every month to children from birth to age five in the singer's hometown of Sevier, Tennessee. “I thought, maybe Linda and I could do something like this when we retire,” Tim recalls. He placed the brochure on his desk as a “reminder”.

    Five years later, now retired and with that brochure still on the desk, Tim clicked on imagination library com. The program had been opened up to partners who could take advantage of book and postage discounts.

    The quality of the books was of great concern to the Richters. Rather than sign up online, they went to Dollywood for a look see. “We didn't want to give the children rubbish,” says Linda. The books reviewed each year by teachers, literacy specialists and Dollywood board members included classics such as Ezra Jack Keats's The Snowy Day and newer books like Anna Dewdney's Llama Llama series.

    Satisfied, the couple set up the Richter Family Foundation and got to work. Since 2004, they have shipped more than 12,200 books to preschoolers in their area. Megan Williams, a mother of four, is more than appreciative: “This program introduces us to books I've never heard of.”

    The Richters spend about $400 a month sending books to 200 children. “Some people sit there and wait to die,” says Tim. “Others get as busy as they can in the time they have left.”

    If you thought pilots dimmed（调暗）the lights before takeoff to give you some shuteye, think again. Believe it or not, the dim lighting could actually help save your life in case of a plane emergency.

    The dimmed lights before taking off the runway and landing are a flight precaution used to help passengers' eyes adjust quicker during an emergency escape. “Going from a brightly lit environment to one that's completely dark would require some time for our eyes to focus and see the escape slide,” Alice Theriault, service director for Air Canada wrote in a press statement. “Since we need to have all the seconds on our side in the event of an emergency, dimming the lights is one of many steps we take to ensure the safety of our customers.”

    The phenomenon that your eyes see those strange speckles (小斑点) as your sight adjusts to a dark place after being in a light place is called dark adaptation. It normally takes our eyes about 20 to 30 seconds to see best in a dark room. The brighter the lights, the longer it takes for our eyes to adjust, which is why dimming the plane lights could shorten your “dark adaptation” time since you haven't been sitting under fluorescent bulbs (荧光灯) all flight.

    Not only does dimming lights add valuable time to the escape process, but it reduces the tension on your eyes if you need to look outside, or see the emergency lighting along the passage. “It helps keep you in the right direction.” Patrick Smith, an airline pilot and author of Cockpit Confidential told The Telegraph. “It also makes it easier for flight attendants to assess any outside risks, such as fire or debris, that might affect an escape.” So next time a pilot dims the lights, just know it's for your safety, even though it creates a gentle atmosphere for your takeoff into the sky.

    I found the last outdoor table at my favourite cafe. Reading as I ate my breakfast slowly, I was enjoying the feeling of the cool wind and the warm sun when a table next to me opened up. A woman, who had been standing nearby, clearly waiting for a seat, stepped towards the table. But from the other direction, straight from the parking lot, came a man who got to the table first.

    The woman, with a smile on her face, explained that she'd been keeping her eye on that table for several minutes and had been on her way over. The man, also smiling but determined, told her she was out of luck.

    She stood off the side, clearly disappointed, and greeted her friend with the disappointing news. I sat at my table, taking in the scene, and suddenly I realized that I had an opportunity to be kind.

    I stood up and asked her to come to my table. Quietly, I told her I had seen what had happened, and I was happy to give her my table. I was only going to be there a few more minutes anyway, so I was happy for her and her friend to have the seat.

    "But where will you sit?" she asked. I was almost done eating, I said, and I would find a seat at the counter (柜台) inside. She thanked me and beamed with delight as she invited her friend to sit down.

    Thinking about it as I finished up, I realized that whether or not the woman had acceptable demand for the table was unimportant. The feeling of the situation -- the look of hurt on her face -- had struck me, and I had the ability to do something about it.I just hope that woman's morning at the cafe was great. I know mine was.

    I was once told, “You are wasting your time on a career that will give you no money or comfort”.

    I explored my interests for years and finally decided to be a journalist. However, I'm still influenced by others' arguments: print publications are being replaced by web versions where content is updated nearly every time you refresh the browser. But I hold onto my decision. Why? For the simple, yet powerful reason that it makes me happy in a way that no amount of money ever could.

    Rarely have I found others who think like this, and I find it very disappointing when I hear students trying to design their lives on the basis of factors (因素) other than keeping to their passions and interests.

    Factor number one is parents. They certainly have a right to be a part in their children's lives, but sometimes their words create more stress than encouragement. Instead of trying to make their children happy, as their original purpose may have been, parents can end up limiting their children's dreams and desires until nothing remains but the hard seeds of a cruel reality.

    The second factor is money. I had a conversation with my college friend one afternoon, which explains this point.

    “What happened?” I asked him after he said he had changed his major. “I thought you wanted to be a photographer.”

    “I do,” he said, “But there is no money in it. Don't worry,” he added, probably feeling my worry. “I'm happy where I am.” I was ready to believe that, but as we kept on talking, he continuously interrupted me to point out the beauty of this view and that view, saying he wished he had taken his camera with him.

    Naturally, we cannot predict where we will end up with our choices. Our ideas and plans could change as we progress. However, at this stage in our lives when so many voices are telling us who we should be, we need to value our individual dreams, not to abandon them, because they may be the only things left that tell us who we are.
