3 . In a normal year, Dayna Reber, a business analyst for a technology consulting firm in Camp Hill, Penn., would finish reading around three books. Thanks to the way Covid-19 has completely changed her daily routine, however, Ms. Reber, 30— who now works from home and rarely socializes offline — has polished off 46 volumes so far in 2020. And that count doesn’t include the bedtime stories she reads to her 4-year-old.
For Ms. Reber and others, lockdown has brought back a passion for reading, both as beneficial time-filler when stuck at home and as a trusty escape. “When the coronavirus hit, I just felt a need to get away from TV and screens.”
If binge (放纵地) reading hasn’t fully replaced binge-watching Netflix shows quite yet, the trend is certainly making strides. In August 2020, year-over-year sales of print books in the U.S. were up 13%, according to NPD BookScan, which tracks book sales across the U.S. Publishers also report a notable increase in purchases of e-books, as well as all books about politics or related to civil rights, racism and diversity.
Independent booksellers, as well as publishers and authors, deserve considerable credit for fueling the page-turning trend. In March, Octavia Books introduced free shipping or delivery within New Orleans on orders of $25 or more. The bookstore also hosts author events via Zoom. And in Illinois, Page 1 Books established a subscription service, where customers fill out an online profile, noting their literary tastes, and then receive a package each month, a mix of hardcovers and paperbacks.
Jamie Miller, 34, a book blogger and “book-stagrammer” who lives in Harleysville, Penn, has long been a committed reader, but she says the hobby has meant far more importance this year. She now schedules a block of time every morning to read, typically a love or vivid novel. “Everything became so chaotic around me that it was just like what can I control?” said Ms. Miller. “My brain just wants something guaranteed to be a happy ending.”

4 . Ariel Procaccia has thought a lot about how to cut a cake over the last 15 years. As the father of three children, he knows how hard it is to divide a birthday cake to everyone’s satisfaction. But it’s also because Procaccia’s work focuses on exploring the mathematical rules for dividing stuff up fairly. One way to do that is to think abstractly about dessert.
For decades, researchers have been asking the seemingly simple question of how to cut a cake fairly. The answer reaches far beyond birthday parties. A mathematical problem at its heart, cake cutting connects strict reasoning to real-world issues of fairness, and so attracts not only mathematicians, but also social scientists, economists and more. “It’s a very elegant model in which you can distill what fairness really is, and reason about it,” Procaccia says.
The simplest approach is called the “divider-chooser” method, where one person cuts the cake into two equal pieces in his view, and the other person picks first. Each receives a piece that they feel is as valuable as the other’s. But when personal preferences are taken into account, even the easiest rule becomes complicated. Suppose Alice and Bob are to divide a cake, and Alice knows Bob prefers chocolate, she may knowingly divide the cake unequally so the smaller piece contains more chocolate. Then Bob will choose according to his preference, and Alice will get the larger piece. Both of them are satisfied with what they get, but the meaning of fairness changes in this situation.
The cake is a symbol for any divisible good. When cake-cutting principles are employed to settle disagreements, they are potentially helping the world find solutions. Procaccia has used fair division algorithms (算法) to model food distribution. Social scientist Haris Aziz is exploring situations ranging from how to divide up daily tasks to how to best schedule doctors’ shifts in hospitals.
Even after decades of investigation, cake cutting isn’t like a simple jigsaw puzzle (拼图) with a well-defined solution. Instead, over time, it has evolved into a kind of mathematical sandbox, a constructive playground that brings together abstract proofs and easy applications. The more researchers explore it, the more there is to explore.

Once a person completes the challenge, they’re supposed to issue the same challenge to several other people, usually three, which is why the challenge has been growing and growing.
Since the beginning of June, the game has spread across social media timelines and late-night talk shows in the US. According to Facebook, more than 15 million people so far have posted,

6 . Halloween candy could be in for a California big change. State lawmakers last month passed the California Food Safety Act, which bans four materials found in popular snacks and packaged foods - including candy corm and other Halloween treats. Set to take effect in 2027, the ban will lead candy and food producers to change their formulas for products sold both in California and elsewhere around the country.
The law bans the production and sale of some materials, which are used in processed foods including kinds of instant potatoes and sodas, as well as candies. The additives (添加剂) have been linked to increased risks of cancer and nervous system problems, according to the Environmental Working Group, which started the act, and are already banned in many other countries.
Food producers and their lobbyists (说客) opposed the law, arguing the conclusion that the four additives are unhealthy should be made by the Food and Drug Administration (FDA). They thought that evaluating the safety of food materials and additives should rely on the scientific accuracy of the FDA. But food safety advocates say the FDA has moved far too slowly in regulating food chemicals. It’s unacceptable that the U.S. is so far behind the rest of the world when it comes to food safety.
California’s act made headlines this year as a “Skittles (彩虹糖) ban” that would wipe popular candies off California shelves. But supporters of the act said the intention is simply to require changes in the materials, as has already happened in Europe. Perhaps the most standing-out material on California’s banned list is red dye No. 3. It is allowed only in candied and cocktail cherries in the European Union but more than 3,000 products contain the chemical in the U. S. The list includes items like frosted pretzels and scores of brand-name candies such as Peeps and Pez. It also includes items like fruit cocktail cups, protein drinks, and yogurts.

8 . One of Twitter’s main characters recently was a man who chose to keep his middle seat between a couple on a flight instead of moving to the side. The situation raised some questions: Who are these middle-seat lovers? What do they want?
Many of the thousands of replies suggested that the majority of the flying public cannot understand why someone would ever choose the middle over a window or an aisle (走廊). But among the majority appeared a few people who endorse middle seats. “In the middle seat I don’t feel I should lean one way or another and generally sit pretty comfortably,” one person wrote. Another added: “I’m not getting hit by someone walking down the aisle or luggage either.”
Kyle Burke, in Florida, said on Twitter that he usually exchanged seats when asked. “I didn’t want to sit between a couple that were upset with me,” he told The Washington Post. At 6-foot-7, Burke, 41, said he didn’t fit well in plane seats, anyway. So, he preferred the middle, which gives him double chance of having a chatty neighbor.
Frederick resident Samantha Jones told The Post by email that she usually chose the middle seat when traveling alone. As a mother of three, “Having personal space is a far-off memory.” she said. “Middle seats have the least amount of responsibility,” she wrote. “I don’t control the window shade and only have to get by one person to get out or to go to the bathroom.”
Despite the few fans, middle seats are still not likely to get much respect. “There’s nothing good in the middle seat,” Scott McCartney, the writer of the journal Middle Seat said. “The position’s infamy (臭名昭著) was part of the reason for the journal’s name.” He added: “People really care about the ‘middle seat’, so they are more likely to pick up this magazine on seeing it.”

9 . Greece has criticized the United Kingdom for canceling (取消) a planned meeting between Prime Minister Kyriakos Mitsotakis and UK Prime Minister Rishi Sunak, apparently so that Sunak could avoid talking about ancient artefacts (历史文物) that Greece says were taken illegally. Mitsotakis and Sunak were set to meet on Tuesday, but Sunak canceled it on Monday, reportedly after learning that Mitsotakis planned to talk about the Parthenon sculptures.
The UK government initially believed Mitsotakis would not talk about the sculptures, which are now in the British Museum. The sculptures were once part of the Parthenon in the Greek capital Athens. The row (纠纷) became more serious after Mitsotakis told the BBC on Sunday the UK’s offer to store some of the sculptures in London and some in Athens was akin to cutting the Mona Lisa in two. He also said the sculptures had been essentially stolen.
Mitsotakis said he was deeply disappointed by the abrupt cancellation of the meeting. “Those who firmly believe in the correctness and justice of their positions are never hesitant to engage in constructive argument and debate,” he was quoted by The Associated Press as saying. The BBC reported that sources in the Greek government were puzzled and annoyed by the meeting cancellation.
Greece has long criticized the way in which the Parthenon sculptures ended up in London, after they were bought by British diplomat Lord Elgin and shipped to the UK between 1801 and 1804. Because the two nations disagree on the legality of the deal and have firm positions, they have tended to avoid talking about the issue during high-level diplomatic meetings.
The UK’s Transport Secretary Mark Harper said on the BBC’s Breakfast program on Tuesday that it was regretful that the prime ministers would not meet during Mitsotakis’UK visit. He said Mitsotakis had been offered the chance to meet instead the UK’s deputy prime minister, Oliver Dowden, but he had refused the meeting. “The views of Greece on the Parthenon sculptures are well known,” Mitsotakis was quoted by The Guardian as saying. “I had hoped to have the opportunity to discuss them with UK Prime Minister along with other international challenges. ” The UK’s opposition Labour Party criticized Sunak for canceling the meeting and said his behavior appeared disrespectful.

10 . Janet, now 37, was playing with her new pet dog, Stitch, who jumped up, grabbed her sleeve, and tore several holes in her sweater with its sharp teeth. Instead of throwing the sweater away, Janet decided to repair it.
She turned to “visible repairing,” an idea of repairing clothes that leaves an obvious fix. She added bright flowers and other small designs to damaged clothes. “Every time you do a repair, it’s like having bought a new piece of clothes,” says Janet.
Actually, repairing is a great opportunity to realize the urgent (迫切的) need to reduce waste. Sadly, we have become used to replacing things instead of repairing them — and the rubbish is piling up. Worldwide, we throw away 92 million tons of cloth every year. Electronic waste is another growing problem: About 50 million tons of it is created each year around the world.
The good news is that fixing things can help deal with the waste problem. There are some solutions. Due to information online, the popular how-to site iFixit.com , a database (数据库) with nearly 100,000 repair brochures for everything from electronics to clothing, has promoted more than 100 million repairs. In addition, since the first Repair Café opened in2009 in Amsterdam, more than 2,700 cafés have been set up to offer in-person fix-it help in various countries. Organizers set up events, and volunteers with repair knowledge bring their tools. They will try to fix whatever people bring in, for free, and teach visitors how to do repairs themselves.
Fixing things is part of a larger change toward a circular economy —the idea that instead of throwing away things once they are broken or out of date, we reuse or repair them, keeping them out of the landfill (垃圾填埋场) for as long as possible. According to a 2023 report from Circle Economy, a Netherlands-based NGO, if the world changed to a circular economy, we could lower the amount of waste by a third.
