While household robots today do the normal housework, social robots will be much more like companions than mere tools. For example, these robots will be able to distinguish when someone is happy or sad. This allows them to respond more appropriately to the user.

The Jibo robot, arranged to ship later this year, is designed to be a personalized assistant. You can talk to the robot, ask it questions, and make requests for it to perform different tasks. The robot doesn't just deliver general answers to questions; it responds based on what it learns about each individual in the household. It can do things such as reminding an elderly family member to take medicine or taking family photos.

         Social robots are not just finding their way into the home. They have potential applications in everything from education to health care and are already finding their way into some of these spaces.

Fellow Robots is one company bringing social robots to the market. The company's “Oshbot” robot is built to assist customers in a store, which can help the customers find items and help guide them to the product's location in the store. It can also speak different languages and make recommendations for different items based on what the customer is shopping for.

          The more interaction the robot has with humans, the more it learns. But Oshbot, like other social robots, is not intended to replace workers, but to work alongside other employees. “We have technologies to train social robots to do things not for us, but with us,” said Breazeal.

    Adding math talk to story time at home is a winning factor forchildren's math achievement, according to a new research from the University ofChicago. The study from psychologists Sian Beilock and Susan Levine shows amarked 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 beanxious 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 Americans experience high levels of anxiety when they haveto solve a math problem, with a majority of adults feeling at least some worries about math,” said Beilock, professor in Psychology andauthor of Choke, a book about stress and performance. “These math-anxiousparents 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 studentsin the reading group by almost three months in math achievement at year's end.

    It is hardly surprising that clothing manufacturers (生产商)follow certain uniform standards for various features(特征)of clothes. What seems strange, however, is that the standard adopted for women is the opposite of the one for men. Take a look at the way your clothes button. Men's clothes tend to button from the right, and women's from the left. Considering most of the world's population—men and women—are right-handed, the men's standard would appear to make more sense for women. So why do women's clothes button from the left?

    History really seems to matter here. Buttons first appeared only on the clothes of the rich in the 17^th century, when rich women were dressed by servants. For the mostly right-handed servants, having women's shirts button from the left would be easier. On the other hand, having men's shirts button from the right made sense, too. Most men dressed themselves, and a sword drawn from the left with the right hand would be less likely to get caught in the shirt.

    Today women are seldom dressed by servants, but buttoning from the left is still the standard for them. Is it interesting? Actually, a standard, once set, resists change. At a time when all women's shirts buttoned from the left, it would have been risky for any single manufacturer to offer women's shirts that buttoned from the right. After all, women had grown so used to shirts which buttoned from the left and would have to develop new habits and skills to switch. Besides, some women might have found it socially awkward to appear in public wearing shirts that buttoned from the right, since anyone who noticed that would believe they were wearing men's shirts.

In 1987 it was listed as a UNESCO World Heritage site.

Coco Gauff used to visit the Grand Slam tournament (大满贯锦标赛) as a kid to see her idols Serena and Venus Williams. Now she is a champion there herself. On Sept 9, the 19-year-old from the US won her first major women's singles title at the 2023 US Open (美国网球公开赛).

After an average start, Gauff surged to a 2-6, 6-3, 6-2 victory over her bigger, stronger opponent, Aryna Sabalenka, from Belarus, who became the new world No.1 the day after the tournament ended.

Unlike the Williams sisters, who have obvious force and power, Gauff is small and slim. But she moves fast on the tennis court. Forbes magazine said, "She is the quickest and perhaps already the best returner of impossible shots in tennis history."

Even though Sabalenka is a very powerful hitter, it felt like she had to finish each point four or five times, as Gauff's defense was so perfect, noted The Telegraph. This ended up frustrating Sabalenka and caused her to make 46 unforced errors.

Gauff thus became the first American teenager to win the US Open since Serena Williams, then 17, in 

1999. When asked about "taking the torch" from the 23-time Grand Slam winner and the similarity between their tennis careers, Gauff told ESPN, "Serena is Serena. She's the greatest of all time... I'd hope to do half of what she did. But I'm not going to compare myself to her. She's some one that I look up to."

Now, Gauff's big win has left tennis fans wondering: When's her next Grand Slam? That's no easy task. Two of the past four US Open women's champions were teenagers at the time, Canada's Bianca Andreescu in 2019 and the UK's Emma Raducanu in 2021, and neither has come close to repeating their success yet. But one thing about Gauff is certain — that at just 19 years old, the sky's the limit.
