Everybody has one of those days when everything goes wrong. This is what happened to Harry.

    He got up one morning very late because he had forgotten to wind up his alarm clock（闹钟）. He tried to shave（刮脸）quickly and cut himself. When he got dressed he got blood all over his clean shirt, so he had to find another one. The only other shirt that was clean needed ironing（熨）, so he ironed it. While he was ironing it, there was a knock at the door. It was the man to read the electricity meter（表）. He showed him where the meter was, said good-bye and found that the iron had burnt a hole in his shirt. So he had to wear the one with the blood on it after all. By this time it was very late, so he decided he couldn't go to work by bus. He telephoned for a taxi to take him to work. The taxi arrived and Harry got in and began to read the newspaper.

    In another part of the town, a man had killed a woman with a knife and was seen to run away in a taxi. When Harry's taxi stopped outside his office, a policeman happened to be standing there. He saw the blood on Harry's shirt, and took him to the police station. He was kept till 3 o'clock in the afternoon before the police were sure that he was not the man they wanted. When he finally arrived at the office at about four, his boss took a look at him and told him to go away and find another job.

    A gaming company in New Zealand is luring employees from around the world by offering unlimited paid annual leave, a share in the company's profits and no set work hours.

    Dean Hall became famous in international gaming circles for being the lead designer on popular video game DayZ. After searching the world for a location for his new gaming studio, Rocketwerkz, New Zealander Hall settled on the small university town of Dunedin on the south island's east coast, where land is cheap and creative start-ups have become an important pan of the city's identity.

    Rocketwerkz's flexible work culture is now drawing talent from around the globe, with Hall receiving 300 messages of inquiry since a local newspaper wrote about his studio last week.

    Last year, when the company was still in its infancy(婴儿期), baby cats would also make a regular appearance in the office as a form of fighting stress, and Friday afternoons are generally reserved for sports and games to end the week on a playful note.

"The first time I heard about the idea of unlimited paid leave in places like Silicon Valley it was about the problems it caused. A culture had appeared where employees took no leave," said Hall.

"So to address that, our staff are issued the standard New Zealand annual leave of four weeks, but they can also take unlimited leave in addition to that."

    Emily Lampitt, from Britain, is a 3D junior artist who has been with the company for a year and a half. She says the flexible work culture was a huge factor in her decision to move to New Zealand.

"The flexibility here has made me feel much more relaxed" she says. I "That internal stress I used to feel in a traditional work environment has gone, so when I am at work now it is because I want to be, because I am passionate(有激情的), not because I am afraid of my boss or watching the clock."

    There is a lot to learn about the creations of Beatrix Potter — not only is she the author and illustrator of one of the world's most famous children's books, The Tale of Peter Rabbit, but also a pioneering conservationist with the spirit of a scientist.

    "Potter grew up as the daughter of a wealthy Victorian family, but along with her brother who filled an entire floor of their large house in London with all sorts of animals," said Anne Lundin, a retired professor for the UW-Madison School of Library and Information Studies.

    "As an adult, she was a frustrated botanical illustrator and scientist. That field was not open to her because she was female," Lundin said. Potter was urged to turn the charming illustrations and stories she wrote in letters to children into books. She wrote 23 books in all — a body of work that has inspired plays, ballets, films and an astonishing amount of merchandise.

    "The Tale of Peter Rabbit is probably the most famous children's book in the world, which was published in 1902 and has really stood the test of time. It's been translated into 36 languages. The parents and grandparents will share it with the next generation," said Lundin.

    Potter also made a mark on the world through her land conservation. "In many ways, she was like Peter Rabbit, venturing into a world of adventure and risk. She withdrew from London as soon as she started making some money on her books to the Lake District and became an extremely important farmer and conservationist. She preserved and passed on 15 farms and over 4,000 acres, which were given back to the country as gifts in the 20th century," said Lundin.

    Even though she was born 150 years ago, she was amazingly modern — her embracing of the natural world, commented Jennifer Blatchley Smith, an artistic director of the show Peter Rabbit Tales to celebrate the 150th anniversary of Potter's birth.

    While staring out of the window during a flight, not everyone will think carefully about the question why airplanes have rounded windows rather than square ones.

    Over the years, aerospace engineering has made huge steps in airplane technology, meaning planes can carry more passengers and go faster. The planes have also changed shape to increase safety—including the windows. As commercial air travel took off in the mid－20th century, airline companies began to fly at higher altitudes to lower their cost—the air density(密度) is lower up there, creating less drag(阻力)for airplanes. However, higher altitudes came with problems, like the fact human beings can't really survive at 30，000 feet. To make that possible, the cabin was changed to a cylindrical(圆柱体) shape to support the pressure inside. But at first, plane builders left in the standard square windows and this expansion meant disaster. The de Havilland Comet came into fashion in the 1950s. With a closed cabin, it was able to go higher and faster than other aircraft.

    However, where there's a corner, there's a weak spot. Windows, having four corners, have four potential weak spots, making them likely to crash under stress—such as air pressure. By curving the window, the stress that would eventually break the window corner is distributed and the chance of it breaking is reduced. Rounded shapes are also stronger and resist deformation(变形), and can thus survive the extreme differences in pressure between the inside and outside of the aircraft.

    Fortunately, designers figured out the lack of design pretty quick. Now we have nice, rounded airplane windows that can resist the pressure of traveling altitude. It gives being able to gaze out of your window to the world from 35，000 feet a whole new outlook, doesn't it?

    One of the great concerns that ornithologists have is that climate change will throw the nesting activities of birds out of sync (同步) with the availability of food for the raising of chicks. For one species, the pied flycatcher, a new study shows that some of its clan are proving to be remarkably adaptable.

    Upon returning to Europe from their African wintering grounds, the flycatchers time their egg-laying to the short period when juicy caterpillars (毛毛虫) are most abundant. During the past three decades this caterpillar peak has advanced by three weeks. Pied flycatchers initially had difficulty adjusting, but over time have started laying their eggs earlier to grab the caterpillars. Some, though, are doing a lot more to improve their reproductive chances of success, according to a study in the Journal of Avian Biology led by Christian Both of the University of Groningen, in the Netherlands.

    Like most bird species, pied flycatchers have long been thought to lay a single clutch of eggs during the breeding (繁殖) season. This was widely considered to be a trait that wouldn't change. Then, in 2007, a Swiss team led by Dr Ravussin began to suspect that clutch numbers were flexible. They discovered a female pied flycatcher that immediately produced a second brood with a new male after raising an early set of chicks. Aware of Dr Ravussin's findings, Dr Both wondered whether this was just a single, odd instance or if second broods might be happening on a larger scale driven by the arrival of earlier springs. So, they cooperate to delve into the data to find out.

    The team studied pied-flycatcher populations in the Netherlands and Switzerland that were known to be among the earliest nesting members of the species. In total, they tracked the egg-laying times and hatchling-rearing success of 8,848 breeding pairs in the Netherlands and1, 372 in Switzerland between1980 and 2018. They found that since 2006, 11 cases of second broods were observed, all of them among the earliest breeders in both populations.

    Further studies ruled out that the birds were making up for a failed first attempt at raising chicks or that the second group of nestlings suffered.

    With no obvious downside to laying a double clutch, Drs Both and Ravussin conclude that the birds are attempting to double their annual reproductive output. While this behavior is still rare, they argue that if the tendency is driven by heritable genes (which it may well be), then a succession of early springs could make the strategy much more common.
