Imagine turning on the GPS and seeing an image of your car from above. As the car drives, the map follows along in real time, informing you of any traffic, pedestrians, animals or other things nearby. Routes and names of road appear over the live stream. It's like the map has come to life.

This type of map isn't available yet. But it could be very soon. In 2014, the WorldView-3 satellite was sent into space. Even though it orbits Earth at more than 370 miles (600km) away, it can take images of objects on Earth that are just 10 inches (25cm) across. Looking all the way from outer space, it can make out a smart phone held in your hand. It can tell what types of cars are travelling down a road. But it can't identify your face or read the cars' license plate numbers.

According to some reports, this satellite and other US satellites have the technology to take even sharper images, with a resolution of up to around 4 inches (10cm). But US law forbids making these super-sharp pictures public. But the idea that anybody might be able to spy on the entire Earth in such detail may seem scary. Live, high-detail satellite mapping could be used to keep tabs on anybody at any time, without the person's knowledge. Ray Purdy of University College London told CNN that he couldn't imagine what this could mean for privacy. "Most satellites are commercially owned, so if you have money, you can have that imagery. It means anyone can spy on anyone." he said.

At the same time, live, detailed maps of the Earth's surface could aid humanity in amazing ways. Satellite images can help experts track storms as they form and chart their paths. At high detail, live maps of a disaster area could quickly reveal people in need of rescue as well as the safest routes in or out. Satellites images are already helping the police catch illegal fishing operations. Higher detail may make it possible to catch other criminals in the act. The images could also make it easier for farmers to watch over their crops or for scientists to find minerals. Also, these images play a very important role in monitoring the health of forests and other landscapes.

    A good joke can be the hardest thing to understand when studying a foreign language. As a recent article in The Guardian newspaper noted, “There's more to understanding a joke in a foreign language than understanding vocabulary and grammar.”

    Being able to understand local jokes is often seen as an unbelievable ice-breaker for a language learner eager to form friendships with native speakers. “I always felt that humor was a ceiling that I could never break through,” Hannah Ashley, a public relations account manager in London, who once studied Spanish in Madrid, told The Guardian, “I could never speak to people on the same level as I would speak to a native English speaker. I almost came across as quite a boring person because all I could talk about was facts.”

    In fact, most of the time, jokes are only funny for people who share a cultural background or understand humor in the same way. Chinese-American comedian Joe Wong found this out first-hand. He had achieved huge success in the US, but when he returned to China in 2008 for his first live show in Beijing, he discovered that people didn't think his. Chinese jokes were as funny as his English ones.

    In Australia, meanwhile many foreigners find understanding jokes about sports to be the biggest headache. “The hardest jokes are related to rugby because I know nothing about rugby,” said Melody Cao, who was once a student in Australia. “When I heard jokes I didn't get, I just laughed along.”

    In the other two major English-speaking countries, the sense of humor is also different. British comedian Simon Pegg believes that while British people use irony (反话)—basically, saying something they don't mean to make a joke—every day, people in the US don't see the point of using it so often. “British jokes tend to be more subtle and dark, while American jokes are more obvious with their meanings, a bit like Americans themselves,” he wrote in The Guardian.

    Adding math talk to story time at home is a winning factor for children's math achievement, according to a new research from a university. The study from psychologists Sian Beilock and Susan Levine shows a marked increase in math achievement among children whose families used Bedtime Math, an iPad app that delivers engaging math story problems for parents and children to solve together.

    Even children who used the app with their parents as little as once a week saw gains in math achievement by the end of the school year. The app's effect was especially strong for children whose parents tend to be anxious or uncomfortable with math.

    Previous research from this group has demonstrated the importance of adults' attitudes about math for children's math success. For example, a recent study found that math-anxious parents who help their children with math homework actually weaken their children's math achievement.

    The new findings demonstrate that structured, positive interactions around math at home can cut the link between parents' uneasiness about math and children's low math achievement.

     “Many people experience high levels of anxiety when they have to solve a math problem, with a majority of adults feeling at least some worries about math,” said Beilock, professor in Psychology and author of Choke, a book about stress and performance. “These math-anxious parents are probably less likely to talk about math at home, which affects how competent their children are in math. Bedtime Math encourages a dialogue between parents and kids about math, and offers a way to engage in high-quality math interactions in a low-effort, high-impact way.”

    Study participants included 587 first-grade students and their parents. Families were given an iPad installed with a version of the Bedtime Math app, with which parents and their children read stories and answer questions involving math, including topics like counting, shapes and problem-solving. A control group received a reading app that had similar stories without the math content and questions related to reading comprehension instead. Children's math achievement was assessed at the beginning and end of the school year. Parents completed a questionnaire about their nervousness with math.

    The more times parents and children in the math group used the app, the higher children's achievement on a math assessment at the end of the school year. Indeed, children who frequently used the math app with their parents outperformed similar students in the reading group in math achievement at year's end.

    Self-driving cars have been backed by the hope that they will save lives by getting involved in fewer crashes with fewer injuries and deaths than human-driven cars. But so far, most comparisons between human drivers and automated vehicles have been unfair.

    Crash statistics for human-driven cars are gathered from all sorts of driving situations, and on all types of roads. However, most of the data on self-driving cars' safety have been recorded often in good weather and on highways, where the most important tasks are staying in the car's own lane and not getting too close to the vehicle ahead. Automated cars are good at those tasks, but so are humans.

    It is true that self-driving cars don't get tired, angry, frustrated or drunk. But neither can they yet react to uncertain situations with the same skill or anticipation of an attentive human driver. Nor do they possess the foresight to avoid potential perils. They largely drive from moment to moment, rather than think ahead to possible events literally down the road.

    To a self-driving car, a bus full of people might appear quite similar to an uninhabited corn field. Indeed, deciding what action to take in an emergency is difficult for humans, but drivers have sacrificed themselves for the greater good of others. An automated system's limited understanding of the world means it will almost never evaluate (评估) a situation the same way a human would. And machines can't be programmed in advance to handle every imaginable set of events.

    Some people may argue that the promise of simply reducing the number of injuries and deaths is enough to support driverless cars. But experience from aviation (航空) shows that as new automated systems are introduced, there is often an increase in the rate of disasters.

    Therefore comparisons between humans and automated vehicles have to be performed carefully. To fairly evaluate driverless cars on how well they fulfill their promise of improved safety, it's important to ensure the data being presented actually provide a true comparison. After all, choosing to replace humans with automation has more effects than simply a one-for-one exchange.

    Sports accounts for a growing amount of income made on the sales of commercial time by television companies. Many television companies have used sports to attract views from particular sections of the general public, and then they have sold audiences to advertisers.

    An attraction of sports programs for the major U.S. media company is that events are often held on Saturday and Sunday afternoons — the slowest time periods of the week for general television viewing. Sport events are the most popular weekend programs, especially among male viewers who may not watch much television at other times during the week. This means the television networks are able to sell advertising time at relatively high prices during what normally would be dead time for programming. Media corporations also use sports to attract commercial sponsors that might take their advertising dollars elsewhere if television stations did not report certain sports. The people in the advertising departments of major corporations realize that sports attract male viewers. They also realize that most business travelers are men and that many men make family decisions on the purchases of computers, cars and life insurance.

    Golf and tennis are special cases for television programming. These sports attract few viewers, and the ratings(收视率) are unusually low. However, the audience for these sports is attractive to certain advertisers. It is made up of people from the highest income groups in the United States, including many lawyers and business managers. This is why television reporting of golf and tennis is sponsored by companies selling high-priced cars, business and personal computers, and holiday trips. This is also why the networks continue to carry these programs regardless of low ratings. Advertisers are willing to pay high fees to reach high-income consumers and those managers who make decisions to buy thousands of "company cars" and computers. With such viewers, these programs don't need high ratings to stay on the air.

    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.
