【推荐1】It’s Friday morning in the year 2050, and you’re running late. You got carried away watching the music video that is playing in the corner of your bathroom mirror while you were brushing your teeth. How will you get to your office at Mega Giga Industries on time?

A quick check of your Internet-connected refrigerator tells you your train is a bit behind schedule, too. So you decide to drive your environmentally hydrogen fuel（环保氢燃料）car instead-or rather, let your car drive you. It’s programmed to know the way and it will get you there without getting lost.

Settling into your office chair, which changes color to match what you’re wearing, you pick up yesterday morning’s newspaper. Printed on reusable electronic paper, it rewrites itself. Now it’s time for your big meeting. Uh-oh! You’ve left your handwritten notes at home. No problem. The smartpen you used has stored an electronic copy of what you wrote.

Your wristwatch videophone（可视电话）suddenly rings. Your best friend’s face pops up on the screen asking what you’re doing this weekend. Will you play virtual soccer with the U.S. Olympic team? No, no. Your friend says, so you have to take the new elevator (made of microscopic fibers many times stronger than steel) 60000 miles into space.

Could this scene really take place in just a couple of decades? The researchers who are now developing all these things think so. These high-tech products（高科技产品）may be as common in 20 years as cell phones today.

Regarding the issue, two American scholars, Andrew McKenzie and Jeffrey Punske, co-authored the article “Language Development During Interstellar Travel”. What has been discussed in the article is the concept of language change over time. They wrote that given more time, new grammatical forms can completely replace current ones.

In a recent interview, McKenzie gamed it out.

“If you’re on a spaceship for 10 generations, new concepts will emerge, new social issues will come up, and people will create ways of talking about them,” McKenzie said, “and these will become the vocabulary particular to the spaceship. People on Earth might never know about these words, unless there’s a reason to tell them. And the further away you get, the less you’re going to talk to people back home.”

So if we have Earth English and spaceship English, and they become different over the years, you will have to learn a little Earth English to send messages back, or to read the instruction manuals and information that come with the spaceship.

Also, keep in mind that the language back on Earth is going to change, too, during that time. So they may well be communicating like we’d be using Latin—communicating with this version of the language nobody uses.

The authors concluded that if a study of the linguistic changes aboard a spaceship could be performed, it would “add to its scientific value”.

The project is called Writing On It All, and it’s a participatory writing project and artistic experiment that has happened on Governor’s Island every summer since 2013.

“Most of the participants are people who are just walking by or are on the island for other reasons, or they just kind of happen to be there,” Alexandra Chasin, artistic director of Writing On It All, tells Smithsonian.com.

The 2016 season runs through June 26 and features sessions facilitated by everyone from dancers to domestic workers. Each session has a theme, and participants are given a variety of materials and prompts and asked to cover surfaces with their thoughts and art. This year, the programs range from one that turns the house into a collaborative essay to one that explores the meaning of exile (流放).

Governor’s Island is a national historic landmark district long used for military purposes. Now known as “New York’s shared space for art and play,” the island, which lies between Manhattan and Brooklyn in Upper New York Bay, is closed to cars but open to summer tourists who flock for festivals, picnics, adventures, as well as these “legal graffiti (涂鸦)” sessions.

The notes and art scribbled (涂画) on the walls are an experiment in self-expression. So far, participants have ranged in age from 2 to 85. Though Chasin says the focus of the work is on the activity of writing, rather than the text that ends up getting written, some of the work that comes out of the sessions has stuck with her.

“One of the sessions that moved me the most was state violence on black women and black girls,” says Chasin, explaining that in one room, people wrote down the names of those killed because of it. “People do beautiful work and leave beautiful messages.”

【推荐2】Sharing E Umbrella, a new umbrella sharing company based in Shenzhen, China, recently announced that it had lost most of the 300, 000 umbrellas since it was set up.

China’s sharing economy has been growing rapidly, with companies offering anything from bicycles and basketballs to phone batteries for people to rent. Customers make a small deposit (押金) and get to use the thing for a daily cost, with a fine put in place for every day if they fail to return the product in time. It’s a simple business model, and market data shows that people see sharing as a cheap and convenient way to cut down waste.

Zhao Shuping founded the Sharing E Umbrella, an umbrella sharing service, in April. By the end of June, he had already started in 11 major Chinese cities, including Shanghai, Nanjing and Guangzhou. While picking up the umbrellas was relatively simple, as they were made available (可得到的) at bus and subway stations, the return system turned out to be a different matter. “Umbrellas are different from bicycles,” Mr. Zhao told Chinese news site ThePaper.cn. “Bikes can be parked anywhere, but with an umbrella you need something to hang it on.”

So instead of bothering to return the umbrellas back to a station, a lot of people just took them home, and Sharing E Umbrella has reportedly lost track of most of the 300,000 umbrellas. Considering that borrowing umbrellas requires a 19 yuan deposit, with a fee of 0.50 yuan per half an hour usage, Zhao says that he suffers a loss of 60 yuan per lost umbrella, so the company is now in the red, but he is not ready to stop it just yet. Zhao announces that Sharing E Umbrella still plans to roll out (推出) 30 million nationwide by the end of the year.
