How Long Is a Second?

The length of a second depends on how you’re measuring it. There are 24 hours in a day, 60 minutes in an hour, and 60 seconds in a minute — so surely a second is 1/86400, of a day, right? Well, it turns out that     1     time isn’t that simple.

“The second was     2     based on the length of the day,” Peter Whibberley, a senior scientist at the National Physical Laboratory in the U.K., told Live Science. “People observed the sun passing overhead and started measuring its     3     using sundials (日晷). However, sundials have a few disadvantages. Aside from the obvious problem of not being able to read a sundial when the sun isn’t visible, relying on Earth’s daily turning is surprisingly inaccurate. “The turning is not precisely     4    ,” Whibberley said. “The Earth speeds up and slows down over time.” So how can we precisely measure time if using the length of a day is so unreliable?

In the 16^th century, people turned to technological solutions to this problem, and the first recognizable mechanical clocks began to     5    . The earliest mechanical clocks, which were designed to click at a specific frequency, averaged over the     6     of a year.

By around 1940, quartz crystal clocks (石英钟) had become the new gold standard. However, problems arose, and this was where atomic clocks came in. “Atoms exist only in particular energy states and can only change from one state to another by     7     or giving out a fixed amount of energy,” Whibberley explained. “That energy     8     to a precise frequency, so you can use that frequency as a reference for time keeping.” The astronomical second continued to vary. Every few years, scientists must add a second to allow Earth’s slowing turning to keep up with atomic time.

In fact, scientists are discussing whether it’s time to redefine the second again. But while several important questions still need to be answered before this     9    , it’s clear that the strictly correct definition of a second is     10     to change.

Communication — a thing of the past?

We all think we communicate all the time, and that’s true. There’s also non-verbal communication you could add into the mix — everything we’re saying when we’re not saying anything. But there’s a(n)     1     between saying things to people, or liking and sharing a post on social media, and communication. I’m quite well connected — there’s Twitter, Facebook, Instagram, Snapchat, email, iEverything, but sometimes communication starts to feel like a chore. Check this blog post, read that article someone shared,     2     back to someone else, and answer their questions… Sometimes I feel like a cross between Siri and a mad juggler. Nothing seems to go in and I’m always mixing people up — asking someone how their band is going when they can’t play an instrument or how the job search is going when someone’s just written to say how depressed they are that they can’t find a job.

So it was quite a(n)     3     to spend New Year in the Highlands in Scotland with no phone signal, no internet and no ‘communication’ at all, apart from with the people I was with. Suddenly all the pressure to communicate disappeared. All of our conversations became slower, more inverted and far more interesting. We were a group of 12, a(n)     4     of couples and friends, only one of whom I was at university with, so I was meeting a bunch of new people for the first time. Our conversations veered towards the banal and the humdrum in that we often discussed our plans for the day and what we were going to cook in the evening, but often they went a lot farther and a lot deeper. Tucked up on the leather sofas,     5     dinner, we dissected Brexit and one person even changed their     6     entirely! We shared ideas and theories, plots of books and plays and city trips we’d been on, described family troubles and gave advice, listened to work scenarios and offered pointers, and we had to talk and sketch and use words more than ever before, because you couldn’t say, ‘It’s a great film, you should google it later.’ Some of us even had sore throats from talking so much! In such a short     7     of time, due to the proximity of sharing interconnected cottages and verbal communication, I felt much closer to the new people I’d met and been speaking with than some other people I communicate with in my normal life.

I don’t think our common, current methods of communication come close to being in a small house with lots of people and having to communicate     8    . The brevity of Twitter, the showiness of Facebook, all these aspects contribute to a shallow form of communication that doesn’t challenge you to     9     your feelings and motives enough. ‘Liking’ something is an instant response but what does it really say about your opinion of something? It’s a(n)     10     response to millions of other people, whereas you and your thoughts are unique. If we’re not careful, perhaps we might forget how to communicate on a deeper lever.

All Change in Curitiba!

Like many other major world cities, Curitiba in southern Brazil has had to deal with issues such as pollution, poverty, and limited public funding. However, the architect and three-times mayor of the city, Jaime Lerner, has introduced some     1     solutions.

As part of his ‘Master Plan’, Lerner hoped to make the city more environmentally friendly. He initiated a recycling scheme. In return for delivering recyclable rubbish to specified     2     points, residents receive a bag of vegetables or bus tickets. As a result, Curitiba now has one of the highest recycling rates in the world. Lerner also ordered the     3     of 26 urban parks. As well as preventing pollution, these control flooding.

Lerner did not win over all the city’s residents immediately, however. When his plans to     4     part of the centre were passed, local businesses were up in arms, fearing a reduction in profits. Realising he needed to act quickly, Lerner had the     5     of six blocks completed within three days. When a group of motorists attempted to drive through the new pedestrian area, Lerner arranged for local primary schools to hold a painting workshop on the streets. The drivers were forced to turn back. Luckily for Lerner, this rebellion was     6    . The increase in profit rapidly persuaded shop owners to change their minds.

Lerner’s determination helped     7     the Curitiba of today. The average income per capita has risen from a level that was below the Brazilian average in the 1970s to 66% above the average, and surveys indicate high levels of resident satisfaction.

So, is it all just one big success story? In some respects, Curitiba may have been too successful for its own    8    . People and businesses have come to the city, which now has more than 1.8 million residents. This has put the city under enormous stress. Forty years ago, buses transported 54,000 passengers a day. Now the number is 2.3 million. According to some experts, the transport system has reached its     9     efficiency capacity. Following a rise in complaints about the noisy and     10     buses, the service is in decline.

The office used to be a place people went because they had to. Meetings happened in conference rooms and in person. Desks took up most of the space. The kingdom of Dilbert and of David Brent is now under threat. The pandemic has     1     the office to competition from remote working, and brought up questions about how it should be designed in the future.

Start with what the office is for. In the past it was a place for employees to get their work done, whatever form that took. Now other conceptions of its role strive for attention. Some think of the office as the new offsite (异地活动) . Its purpose is to get people together in person so they can do the things that remote working makes harder: establishing deeper relationships or     2     in real time on specific projects. Others talk of the office as a destination, a place that has to make the idea of getting out of bed earlier, in order to socialize with people who may have covid-19, seem       3     .

In other words, a layout that is largely devoted to people working at desks alongside the same colleagues each day all feels very 2019. With fewer people coming in and more emphasis on cooperation, fewer desks will be       4     to individuals. Instead, there will be more shared areas, where people in a team can work together flexible. More hot-desking (轮用办公桌) will also necessitate storage space for personal     5     : lockers may soon be back in your life.

To     6     gaps between teams, one strategy is to set aside more of the office to present the work of each department. Another option is to provide everyone with drink. Expect more space to be set aside for     7     and events. Bars in offices are apparently going to be a thing. Robin Avia of Gensler, an architecture firm, says she is seeing lots of       8     for places, like large auditoriums, where a company's clients can have “experiences”.

Designs for the post-covid office must also allow for hybrid work. Meetings have to work for       9     participants as well as for in-person contributors; cameras, screens and microphones will multiply. Gensler's New York offices feature mini-meeting rooms that have a monitor and a half-table sticking out from the wall below it, with seating for 4 or 5 people arranged to face the       10    , not each other.

Pokemon Stickers Are Back for Koreans Nostalgic (怀旧的) for Childhood

Small pastries include a surprise sticker, and the goal is to find all 159 varieties — just like a trend more than 20 years ago.

Jeong Bo-ram’s new fascination has him     1     mass-produced pastries(糕点), delivery trucks and his childhood memories. His     2     are $1.20 bakery items sold with random Pokemon stickers that fly off store shelves in South Korea.

Just a few short of a full 159-sticker collection, 29-year-old Mr. Jeong has gone to more than 10 convenience stores and supermarkets a day, often leaving empty-handed. He has paid hundreds of dollars. He has learned the evening     3     times throughout his neighborhood to know when fresh drop-offs occur.

More than two decades ago, the Pokemon sticker-treat duo caught on with a generation of South Korean children, before the craze passed after a few years and the products were discontinued. Now the goodies are back just in time for the country’s broader retro boom,     4     by adults nostaglic for simpler times.

South Koreans are going to great     5     to live out the Pokemon tagline of “Gotta catch ’em all,” with some     6     the stickers in display booklets. Pokemon, originally a Japanese game for the Nintendo Game Boy that     7     hundreds of monster characters, has expanded into globally popular animated series, toys and video-games,     8     the recent hit Pokemon Go for smartphones.

Retailers have posted signs on their entrances that read, “We have no Pokemon bread,” while some store owners are     9     of bundling the in-demand pastries with unpopular items. Hunters camp outside supermarkets early in the morning. The rarest of stickers, such as that of the legendary characters Mew (梦幻) and Mewtwo (超梦), fetch $40 online. A full collection     10     more than $700, the listings show. Actual children also try to find the stickers, but adults are using their greater resources for the hunt.

Ko Hyo-jin shrieked when she ripped open a package of “Diglett Strawberry Custard Bread” recently and discovered inside a sticker of Mewtwo - a two-legged monster shown extending its paw. She immediately dialed up her husband. “It felt like winning the lottery,” said the 39-year-old homemaker in the Seoul Suburbs.

The nostalgic chase has been embraced by young adults facing Korea’s stagnant economy, soaring real-estate prices and a tight labor market.

American authorities arrested Masphal Kry, an official in Cambodia’s forestry administration, last November when he was heading to an international meeting about trade regulations for endangered species in Panama. Prosecutors accused him of conspiring with a smuggling ring. The contraband (违禁品): monkeys,     1     long-tailed macaques. His     2     allegedly grabbed wild macaques in Cambodia’s national parks and bribed officials to label them as captive-bred. Fake papers allowed Vanny Bio Research, a Cambodian pharma company, to ship these unfortunate primates (灵长类动物) to America for use in research. Mr Kry is facing trial in Florida’s Southern District Court. The federal government funds seven National Primate Research Centres (NPRCs), which     3     in total around 20,000 primates, not only macaques but also baboons and marmosets. These centres then     4     primates to labs across America. NPRCs have fulfilled only a third of requests for untested-on macaques in 2021 and prices have soared. Before the covid-19 pandemic a rhesus macaque cost $8,000; by 2022 they had     5     $24,000. Another species, long-tail macaques, is probably per pound currently the most expensive     6     wildlife, says Lisa Jones-Engel, a science adviser at PETA, an animal-rights group.

Getting lab monkeys from abroad became harder during the pandemic. Chinese authorities banned the export of all primates in early 2020. The Chinese government wanted to     7     the country’s wildlife trade, which is thought to encourage the     8     of pathogens—like sars-cov-2—from animals to humans.

That forced American companies to rely on less     9     South-East Asian suppliers. Many scientists believe poaching is prevalent across Cambodia. In February, the Department of Justice subpoenaed Charles River over 1,000 juvenile macaques the pharmaceutical company had bought from Cambodia; the DoJ suspected they were     10     in the wild then exported. These primates are now in Texas and Maryland but also in dilemma: they cannot be tested on, nor can they be flown back to Cambodia.

Knives Out film director Rian Johnson has revealed a secret in the world of product placement—bad guys cannot use an iPhone on the big screen. Johnson, whose film    1     include Star Wars: The Last Jedi and Looper, reveal the behind-the-scenes secret to a reporter.

He pointed out the Apple warning, saying, “Apple, they let you use iPhones in movies, but, and this is very    2    , if you’re ever watching a mystery movie, bad guys cannot have iPhones on camera.” He revealed the    3     to Who Do It On Films, a programme, as he discussed Knives Out, a murder mystery film with an ensemble(全体) cast featuring Daniel Craig, Toni Collette and Jamie Lee Curtis. Johnson    4    , “So oh no, every single filmmaker that has a bad guy in their movie that’s supposed to be a secret    5     wants to murder me right now.” So how common is this? Fairly so, says product placement specialist Darryl Collis.

“With feature films, every production needs the brand’s    6     to show a brand within the film,” he told ITV News. “So if Apple don’t give clearance for that to appear, then what will have to happen    7     is they’ll either have to remove the logo or that brand can’t appear in the film.” A good example would be: Coca Cola were    8     in a film called Slumdog Millionaire, but they were shown in a    9     light so what they said to the producers is: “You cannot show our brand, you need to take away the labels.” “They never gave clearance for the brand to appear so they had to remove the labels at the end of the post production.”

But will it    10     movies for film fans?

Film critic Hannah Woodhead works at Little White Lies magazine, she told ITV News now one of the secrets of Hollywood is out of the bag, she’ll be much more eagle-eyed.

Huizhou heritage comes to life

It was a natural choice for veteran Huang Yu, after serving in the army and owning a business in Hangzhou, Zhejiang province, for years, to go back to his hometown in Xidi village, Huangshan, Anhui province, in 2016. He took over the homestay his parents opened when he was a middle school student.

In 2000, Xidi and the nearby Hongcun village were declared World Heritage sites by UNESCO for their outstanding     1     of rural architecture dating to the Ming (1368-1644) and Qing (1644-1911) dynasties. Now, walking along the bluestone streets in Xidi or Hongcun, visitors can appreciate the distinctive Huizhou-style houses,     2     white walls, dark tiles and layered horse-head gables, and feel like they are immersed in a traditional Chinese ink painting.

This level of preservation could not be achieved without the participation of local residents. According to Huang, this awareness is not new - since all streets and alleys in Xidi are paved with bluestone,     3    , street dealers carrying wares on shoulder poles were forbidden from letting their poles touch the ground in order to protect the bluestone.

A local folk     4     says: “One is not lucky to be born in Huizhou. At 13 or 14 he is kicked out of his hometown to make a living.” It     5     at the struggles once endured by the people of Huizhou. Toward the end of the Ming Dynasty, a group of Huizhou merchants became famous, trading in salt, wood and tea, and working as pawnbrokers (当铺老板) with a reputation for     6     and honesty.

“Some folk customs have been retained and newly     7     toward tourism, offering glimpses into the lives of the ancient Huizhou people.”These customs are revived as a demonstration for tourists, and to maintain the     8     of traditional culture. Zhang Wangnan, director of the China Huizhou Culture Museum in Huangshan says “This     9     the combination of intangible with tangible cultural heritage.”

He further suggests that the old Huizhou villages explore and find their own unique, marketable themes. “Each of them should find a     10    local feature, whether it is tea, chrysanthemum or rapeseed flowers, and then make it the theme of the village, so that they can give full play to their distinctive cultural charm.”

Top work-life balance benefits for 2023

“Flexibility is the gold standard of work-life balance benefits,” says Jonathan Pas, health care leader at consulting firm Mercer.

It’s no surprise then that two years after the pandemic forced most office workers to perform their jobs remotely. 78% of employers say they’ll allow employees to continue doing so regularly in 2023, according to a Mercer survey. But there’s still some     1    : only 9% say they will allow employees to work remotely daily.

    2    , flexibility around when employees work is just as important as where. In the survey, 66% of employers said they would offer flexible work schedules over the course of a typical work day, such as specific times during the week to     3     to personal matters and four-day work weeks. Employees no longer want to organize their personal life around a(n)     4     work schedule but instead want the two interwoven, so they can decide what to prioritize and when.

Pas     5     against making hollow promises about a company’s commitment to work-life balance. “If employees feel a disconnection between programs that are rolled out and what senior leaders really expect, credibility is questioned, and the goodwill created through the program is denied.” He cites paid time off to volunteer, which almost half (45%) of companies say they will add to their benefits     6     next year.

Other benefits requiring a broader organizational buy-in are sabbaticals(公休假) and unlimited vacation days. Both benefits encourage employees to pursue interests outside of work with     7     periods off. Still, if they feel a dishonour associated with taking advantage of them, they’ll be hesitant to do so. The relatively low     8     rates for 2023, though—only 12% for sabbaticals and 15% for unlimited vacation—indicate that employers are still against paying employees not to work.

Instead, they prefer to find new ways to give employees more money, with the rise of employer-funded lifestyle accounts, which are often reserved for big-ticket items that might otherwise require some     9    . Nevertheless, only 12% of employers said they would add lifestyle accounts in 2023, and 70% said they are considering them, which could indicate a trend on the horizon.

But perhaps the most telling statistic about the importance of     10     work-life balance is the number of companies that said they don’t plan to offer any additional benefits to support work-life balance: a mere 5%.
