1 . Noted for his profound description of life along the Chinese railway, Wang Fuchun passed away on March 13th at the age of 79. His engaging photographs capture the substance of China’s ever-changing landscape.

Being artistic and good at painting and calligraphy, Wang found that photography bridged the two worlds: he could make art with his camera and increasingly he felt that his goal was not art, but life.

In the late 1970s, when he started taking his photographs, everyone on a railway platform looked reserved and orderly. By the late 1980s, a great rush to the cities had begun on the trains. He recorded young migrant workers shedding their shirts, running with sweat, seeking coolness on top of the seats. He did not ask anyone’s permission to take them, and he preferred to act secretly, like a thief in a way, as it captured the authentic (真实的) moments of people’s lives—and so mirrored all the more clearly how China was changing.

His project was all-consuming. Over 40 years he estimated he had ridden on 1, 000 trains and covered more than 100, 000 kilometers, on every line in China. Each trip was neatly noted down in a notebook; he took about 200, 000 pictures, and logged each by its place. From those pictures, he felt the migrants’ poverty too keenly, and he preferred to capture the hope that pushed people on to trains.

China was rushing to the modern world. Steam was fading; the green-skinned trains acquired fans and air-conditioning. Then came express trains, then high-speed rail. The aisles were clear, the windows sealed. However, in the reclining seats (躺椅座位), everyone reclined. In the ordinary seats, everyone’s noses were buried in their tablets and their phones.

He liked the message of hope; he was proud of what China had achieved. But how sad, he also thought that on that dashing train there was no mess, no collision of life and no good subjects for him, and that Chinese people should once again look so orderly, reserved and unconcerned about each other, even on a train.

2 . Our future selves used to be a riddle. Now, thanks to social media filters (滤镜), we can stare them right in the face. People fell in love with TikTok this month to share themselves “aging” in real time using a filter “time travel”. Set to a sad song, the effect shows the user’s face slowly getting older, complete with wrinkles (皱纹) and sunspots.

Camera filters that age you have been around for years. But advancements in AI are making the results more real. Doctor Aleksandra Brown said the TikTok time travel filter does well in guessing how a given face would age.

As we get older, our facial skin thins, fat dissolves (溶解) and gravity pulls everything downward. Not everyone is pleased about this. One of Brown’s friends didn’t like watching time fly past. She couldn’t stand watching herself age 50 years in 15 seconds-could life really go by that fast? Brown cried herself after using the aging effect on her own young daughter. She won’t live to see her daughter get that old, she pointed out.

For other people, the time travel filter brought up unexpected positive feelings. Actor Jonathan Bennett shared a video saying his own filtered face recalled happy memories of his late father. Nicole Loehle, a 24-year-old in New Jersey, tested the effect with her boyfriend. It gave her a new viewpoint, she said, she could imagine the relationship lasting into their old age.

There’s no correct way to age. But it’s important to remember that no one can stop time or undo its effects. “I keep trying to view aging as a gift.” Brown said, “Some people don’t get to age, unfortunately?”

3 . One day, you might be ordering your favorite pizza from a robot.Researchers at a university in Pittsburgh, Pennsylvania, are working on creating a pizza-making robot.

“Robots are basically preprogrammed to repeat the same actions over and over,” says David Held, a robot expert from Carnegie Mellon University, and one of the members of a pizza-making team．But making pizza has challenges.For instance, the flour (面粉) will become squishy when meeting water, with a shape that can change in many ways.Also, pizza-making requires many steps—such as rolling and cutting—and several tools, including a rolling, a knife and so on.In what order should the steps be done? Which tools should be picked, and when? “If you need to do a cooking task, there are several levels that you have to reason about,” Held says.Once people get the hang of it, “We don’t even need to think about exactly how we’re doing it- it sort of just happens.But robots can’t really “understand what to do on their own”.

To start, the team used a computer to consider how a robot could lift, fatten, gather, move and cut dough (生面团).The method has two levels of robotic reasoning: one that thinks how it should approach the overall task, and the other that thinks how it should move its “hands” to perform each action．The result was better than with the usual programming techniques.“We got a little bit closer to the right shape than the former methods,” Held says．“‘But there’s still a lot of room for improvement.”

For now, people will continue to make pizza the old-fashioned way: with their own hands.Sill, a pizza-making robot is a good goal.And if a robot could deal with dough, it could also work with other objects that can change shapes.“You can imagine robots helping in hospitals, or robots that clean up toys in day cares,” Held says.“The general goal is to eventually have robots that can help with whatever the task may be.”

4 . When was the last time you used a telephone box? I mean to make an actual phone call — not to shelter from the rain. Ages ago, right? The last time I used a phone box for its intended purpose was…2006. I was conducting auditions (试演) for my play in my tiny old shared house in London. Hoping to impress some talented actors to come and work for me for nothing, I spread some throws over the sofas and lit candles to make it seem a bit more ”young professional”.

As I rushed outdoors to empty the wastepaper baskets, the door swung shut behind me. Suddenly I was locked outside. My mobile phone was inside, but luckily there was a telephone box across the street. So, I called Directory Assistance, got put through to our landlady’s managing agent, and had a spare key sent to me with just enough time to get back in before the actors arrived.

As it has been many years since I last used one, I should hardly be surprised that then are no longer any public telephones near my house. The last one standing has just been turn into a “mini community library”: any passer-by can “borrow” a book from its shelves return it later, or replace it with another title from their own collection.

For a few months after the “library” opened, I didn’t bother taking a look, as I had assumed that it would be stuffed full of cheese love stories. Then I noticed fork conducting spring cleans dropping boxes of voluminous books on various subjects there. And these books were free. This unbeatable price-point encouraged me to experiment with dozens of titles that I would never normally consider buying. And I’ve discovered some great books!

If I ever get trapped outside my house again, my local telephone box will, sadly no longer be able to connect me with my keys. But it can certainly keep me entertained while I wait for my wife to rescue me.

5 . Travel is predicted to look extremely different in 2070.

Take airports for example, paperwork will be a thing of the past. Instead of paper passports,your information will be stored in the cloud. This type of technology won’t just include what we are familiar with today——like fingerprints or face scans—but also your heartbeat, as everyone’s heartbeat is unique.

There will be no need to check in. The facial recognition programme will instead be able to recognise you, match you with your booked flight and send messages to your phone as you walk through the airport without stopping.

Your bags, especially the heavy ones, will be sent directly from your train or taxi to the right plane. And that taxi will not be like the ones we know today. People will be expected to travel to the airport--and around their holiday destinations-in eVTOLs, which refers to électric air taxis that can take off and land without a runway.

As for the trouble of packing, 3D printers will provide perfect solutions. Simply provide your destination with your size using a body scan before you fly and, upon arrival, you will find a wardrobe(衣橱) filled with 3D-printed clothes. When you leave, these clothes will be recycled and. reprinted for the next tourist. Not only will this solve the problem of packing, but also make holiday fashion more environment-friendly.

While the predictions might seem unbelievable now, you only have to look back 50 years to realize it’s all possible. Think back to 1973 when smartphones were just a wild dream. “Google” seemed like a made-up word then, and notebook computers were still almost years away from being invented. Similarly, when we look forward to the next 50 years, the possibilities for development in technology for travel are endless.
