“Do you have any idea how hard it is to be a kid?!” My 7-year-old once asked me. My initial reaction to her complaint (抱怨) was eye-rolling, along with thinking, “Being a kid is hard? Are you kidding me?” as I mentally counted all the hard things that her grown-up mama did.

    However, as I thought about it a bit more, I realized how silly my reaction had been. Yes, as we adults look back on our childhood, being a kid seems carefree and easy and full of fun. Coloring at school! Playing games! Riding bikes! How could that be hard? So I asked my daughter why being a kid was so hard.

    “Well, because you don't have your own phone, and you can't eat in the living room,” she said.

     I asked if anything else was hard about being a kid. “Someone else is the boss of you,” she replied.

    I thought some more. What else is hard about being a kid? Well, sometimes, we don't really take kids seriously.

    There are times when I've responded to my children's tears with “It's not bad,” or “You don't need to be upset about that.” Because I believe that a cancelled playdate or a lost toy is no big deal. But for my little ones, it is.

    We don't intentionally ignore these opportunities for connection, but sometimes, in busy moments of parenting, we respond unskillfully. We don't put ourselves in our children's shoes, and we miss an opportunity to practice compassion.

    Compassion means “to feel with” or “to suffer with” another person. It means seeing something the way they do, and experiencing it with them.

    Here's what I've learned about being a more compassionate parent, and I hope other parents can do the same thing.

Five years ago, when I taught art at a school in Seattle, I used Tinkertoys as a test at the beginning of a term to find out something about my students. I put a small set of Tinkertoys in front of each student, and said: "Make something out of the Tinkertoys. You have 45 minutes today - and 45minutes each day for the rest of the week."

    A few students hesitated to start. They waited to see the rest of the class would do. Several others checked the instructions and made something according to one of the model plans provided. Another group built something out of their own imaginations.

    Once I had a boy who worked experimentally with Tinkertoys in his free time. His constructions filled a shelf in the art classroom and a good part of his bedroom at home. I was delighted at the presence of such a student. Here was an exceptionally creative mind at work. His presence meant that I had an unexpected teaching assistant in class whose creativity would infect（感染）other students.

Encouraging this kind of thinking has a downside. I ran the risk of losing those students who had a different style of thinking. Without fail one would declare, "But I'm just not creative."

"Do you dream at night when you're asleep?"

"Oh, sure."

"So tell me one of your most interesting dreams." The student would tell something wildly imaginative. Flying in the sky or in a time machine or growing three heads. "That's pretty creative. Who does that for you? "

"Nobody. I do it."

"Really-at night, when you're asleep?"

"Sure."

"Try doing it in the daytime, in class, okay?"

    Eco-friendly Vauban, lied in the southwest part of Germany, has everything－tree-lined streets, perfect houses－but it's missing one urban feature of the last 100 years or so: the car. And Vauban residents(居民) don't mind one bit. Vauban doesn't ban cars entirely. Rather, it just tries to reduce the use of cars by creating “parking-free” and “car-free” living. In Vauban, parking spots are a no-no private property(私人财产). Cars can only be parked in public parking lots, so living without a car saves residents the cost of parking in the public lot. Cars also are prevented from using certain roads and must stick to strict speed limits. With these limitations, fewer than 20 percent of residents own cars. Without cars, bikes are almost religion in this small town. Kids pick them up even before they can ride one. Vauban is about much more than just using two wheels instead of four. In Vauban , residents ride bikes and even receive money from the electric company for selling electricity back to the power grid (电网系统). It's an environmentally-friendly city of the future, with organically grown food, renewable energy, and carbon-neutral homes. And now, with a population of 5,500, it's attracting attention from around the world. Can an eco-friendly city like Vauban be a model for Americans to stop their over-reliance on the cars?

    Sometimes when I watch a news report what's in the back of my mind is what isn't being reported or stressed. While this eco-friendly city is inspiring in that it shows residents getting exercise and fresh air through the majority use of bicycles, as well as good old fashioned walking, common sense would tell you that even for a place like Vauban, Germany, it owes its existence to the cars.

    Do you think that bicycles were able to transport all the construction materials that were needed to build and maintain the eco-friendly homes and businesses in Vauban? It took cars to help build this utopia. It's one of the paradoxes of life that sometimes in order to get away from relying on something like the car, you actually have to rely on that very thing at the beginning and into the foreseeable future to some degree.

    I myself haven't owned a car for more than 14 years, and mostly get around town running, walking, or using public transportation. There are times I wish I had one, since it would make many things easier, but overall I'm glad not to have to deal with the headaches of owning a car, which caused me to get rid of it in the first place. And all the walking and running has helped to keep me fit and healthy.

    To get even close to being like eco-friendly Vauban, Americans will need to absolutely change the way they live. Commuting(乘车上下班) patterns will have to change, public transportation will have to be invested in, and so on. And though ending our love affair with the car will be impossible during my lifetime, we may at least start to see more Vauban-like areas in the USA.

    We can hope that Americans will consider using their feet more to get around, cutting down on pollution, and giving themselves some more exercise.

    Janus, the Roman god, has two faces looking in opposite directions. So does artificial intelligence (AI). On one side are the positive changes, enabling people to achieve more, far more quickly, by using technology to improve their existing skills. Look the other way, though, and there are plenty of potential pitfalls.

    Like Janus, technological change may also cause disruption(混乱), but AI is likely to have a bigger impact than anything since the appearance of computers, and its consequences could be far more disruptive.

    In the years ahead, AI will raise three big questions for bosses and governments. One is the effect on jobs. Although CEOs publicly praise the broad benefits AI will bring, their main interest lies in cutting costs. One European bank asked Infosys to find a way of reducing the staff in its operations department from 50,000 to 500. The McKinsey Global Institute estimates that by 2030 up to 375m people, or 14% of the global workforce, could have their jobs replaced by AI.

    A second important question is how to protect privacy as AI spreads. The internet has already made it possible to track people's digital behavior in minute detail. AI will offer even better tools for businesses to monitor consumers and employees, both online and in the physical world. Consumers are sometimes happy to go along with this if it results in personalised service or promotions. But AI is bound to bring invasion of privacy that is seen as unacceptable. For example, law-enforcement officials around the world will use AI to spot criminals, but may also monitor ordinary citizens.

    The third question is about the effect of AI on competition in business. A technology company that achieves a major breakthrough in artificial intelligence could race ahead of rivals, put others out of business and lessen competition. This is unlikely to happen in the near future, but if it did it would be of great concern.

    It is too early to tell whether the positive changes brought by AI will outweigh the risk. But it will put an end to traditional ways of doing things and start a new era for business and for the world at large.

    It seems that electronic devices just keep getting smaller. Scientists in the United States have announced the creation of the first transistor with only two dimensions(二维).

    A transistor is a small electronic device that transfers or carries electronic current. Scientists hope these new 2D transistors will be used for building high-resolution(高分辨率)displays that need very little energy.

    Two groups of scientists created these 2D transistors. They report that the transistors are only a few atoms thick.

    Usually transistors are made with the element silicon(硅). Computer processors, memory chips, TV screens and other electronic devices contain billions of silicon-based transistors. But these very small electrical parts have certain limitations.

    Dimitris Ioannou is an electrical engineering professor at George Mason University. He says the traditional transistor has been improved as much as it can be. He adds that researchers have been looking for new materials with special features and they want transistors to be seen through and soft.

    "If the layers are very thin, the transistor can become flexible, so it doesn't have to be rigid(坚硬的), like it would be in a silicon chip. So people can think of applications like wearable electronics, television screens and other things," said Ioannou.

    These new transistors can also carry higher current. They also can move the current much faster than traditional transistors. This is important for high-definition screens.

    Dimitris Ioannou says the scientific success could prove very useful in the future. "Now, how good and how useful it will be, it's still in the stage of research, but it certainly is an advance," said Ioannou.

    Sweetest Day is always the third Saturday in October. This holiday is much more important in some regions than in others (Detroit, Cleveland and Buffalo being the biggest Sweetest Day cities). It is a holiday that is gaining in popularity every year throughout the country.

    Sweetest Day is celebrated on the third Saturday in October as a day to make someone happy. It is an occasion which offers all of us an opportunity to remember not only the sick, aged, and orphaned, but also friends, relatives and associates whose helpfulness and kindness we have enjoyed.

    Over 60 years ago, a Cleveland man, believing that the city's orphans and shut-ins (卧病在床的人) too often felt forgotten and neglected, formed the idea of showing them that they were remembered. He did this through the distribution(分发) of small gifts. With the help of his friends and neighbors, he distributed these small remembrances on a Saturday in October. During the years that followed, other Clevelanders began to participate in the celebration ceremony, which came to be called "Sweetest Day". In time, the Sweetest Day idea of spreading cheer to the underprivileged(弱势群体)was broadened to include everyone, and became an occasion for remembering others with a kind act or a small remembrance. And soon the idea spread to other cities all over the country.

    Sweetest Day is not based on any single group's religious belief or on a family relationship. It is a reminder that a thoughtful word or deed enriches life and gives it meaning. Because for many people remembering takes the form of gift-giving, Sweetest Day offers us the opportunity to show others that we care, in a practical way.
