    Julian Beever is a well-known British artist. His drawings have appeared on the streets of London, Paris, Tokyo, New York and many other cities around the world. Beever creates what looks like a three-dimensional design (三维设计). From animals to heroes to buildings, the paintings are wonders for our eyes to see.

    In his book Pavement Chalk Artist, Beever shares some of his most attractive and humorous pieces. Here are the examples you will find in the book.

    Philadelphia Eagle, created in the USA, is a huge drawing with an eagle (鹰) landing on an American national flag. Meeting Mr. Frog was created in Spain and is about a realistic- looking (样子逼真的) frog sitting on a lily pad (睡莲叶子). Swimming Pool in the High Street is about a woman relaxing in a swimming pool sinking into the middle of the street.

    Along with an introduction about his background, Beever shares information about his time at home in the UK and abroad. With a fun story coming after each piece of art, this 112- page book is really worth another look.

    An analysis of almost 50 years of competitions—including Eurovision Song Contests and world skating championships—has found that contestants are more likely to win if they are among the last to appear before the judges.

    The study by an American university appears to provide scientific proof that the best man, or woman, does not always win. It found that, on average, the last competitor to appear in the Eurovision Song Contest was more than twice as likely to win as the one who went on first.

    The first rounds of figure—skating championships, for which the running order is selected at random, showed more dramatic results. The final skater had a 14 percent chance of victory, making him or her more than four times as likely to win as the first skater.

    The study showed a gradual worsening of chances for competitors who appeared earlier in the running order. A contestant who appears first in a contest is two percent less likely to win than one who appears second. A contestant who appears second is two percent less likely to win than one who appears third, and so on.

    The findings are published in the March issue of Acta Psychologica, a scientific journal. Robert Hardman, a senior lecturer in psychology at London Metropolitan University who specializes in the science of decision-making, said that the results were interesting. He suggested that the effect was caused by the limitations of the human memory.

    "When people make comparison, they aren't really able to make a lot of fine-grade discrimination. When contestants appear at the beginning of a contest, judges have little to compare them to and are perhaps cautious about the scores they give." he said.

    "Later on, when judges are able to compare the contestants to those that have gone before, they might give more extreme marks because they feel more confident about their judgments."

    Most heroes are not super. They don't appear in comic books, on television, or in movies. They just do what they believe needs to be done to make their world a better place. Bike Batman is one of them.

    Bike Batman is a 30-year-old married engineer who lives in Seattle, Washington. He's a cyclist who also buys and sells bikes as a hobby.

    About three years ago, he was looking for a bike for his wife. He found one on Craigslist, a website where people list things they want to sell. As he often does, he also looked at Bike Index, a popular website that allows users to register their bikes and post reports when they're taken. The bike, which he was considering purchasing, clearly matched one reported stolen on Bike Index.

    Then he called the person who claimed to be the bike's owner and arranged to meet him— supposedly to complete the sale. When the two men met, Bike Batman told the thief, “You've got two options. You can wait until a police officer gets here, or you can just get out of here.” You can imagine what the thief did.

    After that first success, Bike Batman developed a safer routine. When he sees questionable bike ads on Craigslist, he cross-references the image with bikes reported on Bike Index. Once he has confirmed it with the owner, he arranges a meet-up with the thief and will call the Seattle police department so that officers can participate in the action. In more than half of the 22 cases in which he has got back and returned bikes, the thieves have been arrested. In one case, Bike Batman even helped a family recover a wide range of prized possessions that suspects had stolen during a home burglary.

    His nickname came from a discussion with a police officer who suggested he be called “Robin Hood”. Since he wasn't exactly stealing from the rich and giving to the poor, “Batman” seemed a better fit. The idea of a superhero punishing criminals feels pretty silly to him, but the main reason he continues his work is to keep up Seattle's reputation as a friendly city.

    Long before iPhone, the cigarette was the companion of choice for restlessness. And long before Facebook and WeChat, it was tobacco that promised to better your social life. Now, quitting smartphones has become the new quitting smoking.

    Of course, technology does not yellow your teeth, cause disease or lead to cancer. But some individuals are so concerned that device addiction is damaging their mental health. In order to reduce their dependence, even in Silicon Valley, people are turning off the messages that constantly buzz for their attention, banning smartphones from the bedroom and, curiously, changing the colors on their screens to a less tempting scale of gray.

    The big tech companies will have to work out how to respond to this new generation of quitters. Facebook is the first to go public with its attempt, hoping its recent move can make the social network more homely.

Last year the tech industry got a bad name —Big Tech—with unfortunate echoes of other industries that have faced fierce opposition, including Big Tobacco. Like them, the tech industry has to reduce concern from a new generation of activist shareholders （股东） that are questioning its role in the world. These campaigns are never as fierce as those faced by Big Tobacco. In the 1990s, socially responsible investors refused to put money in tobacco stocks.

    It is far difficult for investors to challenge Big Tech and hard to separate the good these companies do in the world-connecting old friends and giving space for people to share their ideas-from the bad. In the meantime, stopping using technology remains problematic. In The World Without Mind: The Existential Threat of Big Tech, Franklin Foer argues that tech should be seen in a similar way to junk food: a convenience that some reject for more continuing nutrition.

    So we need to do more to turn the tide. In the same way that public service announcements made smoking around your children taboo （禁忌）, we can warn parents against losing themselves in their smartphones while taking care of kids. We can also create no-smartphone zones at dinner. Eventually smartphones could be banned from all public places and help us give our attention to the people around us instead.
