1 . 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.

6 . Last August, I visited Melbourne Zoo and saw a baby Sumatran orangutan (苏门答腊猩猩). His birth was part of an international program to help the Sumatran orangutan survive as a species. At the moment these beautiful animals are in danger of disappearing in the next 10 to 20 years.

Melbourne Zoo is a modern zoo. Like most modern zoos, it cares very much about animals. It is not a cruel place. You could certainly argue that zoos were cruel places in the past, but I don't believe you can argue that they are cruel places today.

In the past, zoos were exhibition parks. Their only purpose was to give humans pleasure, by showing them wonderful animals that they would otherwise never see. Because animals were only there for the good of humans, no one took much care of them. They were transported thousands of miles around the world, then locked up in small, lonely cages (笼子). In those days, zoos were cruel.

These days, things are very different. The whole purpose of zoos has changed. Now zoos have three main purposes: education, conservation (保护) and research. They aim to make animals better off everywhere. Because of this, the way animals are cared for is also different.

Education is a big part of the activity at zoos. At Sydney's Taronga Park Zoo, for example, 130, 000 school children attend special programs every year to learn about how animals behave and what they need to live. The aim is to make children learn more about animals now so that they will care about them when they are adults.

Zoos play a major role in the protection and conservation of endangered species. The Sumatran orangutan is just one example of the many animals that are better off because of special programs.

Zoos carry out many important research programs which help animals in captivity (囚禁) and in the wild. Recent research, for example, has shown that many intelligent animals enjoy playing games while in captivity.

Modern zoos care about animals first, and people second. Zoos are not cruel places.

7 . What will future schools look like in 100 years? Imagine future schools in which students are totally engaged in a class. They are concentrating on working together to solve real-world problems. They are self-driven and are coming up with amazing ideas on the spot. They are concerned with each other’s well-being as part of a team. Their concerns reach far beyond the classroom to others all over the globe.

The school of the future will be an amazing melting pot of different peoples coming together to solve real-world problems.

Will they even be called “schools” in the future?

The teacher-student relationship is changing. Teachers are acting more as helpers rather than keepers of all knowledge. Students are driving their own education to the path that they feel best fits them. In the future, employers may not be as concerned with a diploma. They’ll look more at cases and examples of how students contribute to solving real-world problems. They’ll want to know how well they work in a team.

What will problem-solving look like in the future?

Information from the Internet is accessible everywhere and at unimaginable speeds. Kids are connected to news around the world in real time. Imagine someone could put out a request to the global community to help solve an issue in their own community! Classes can adopt an issue and work with other classes around the world in real time to create solutions.

What will information look like in the future?

It’s already everywhere. Users can get flooded by the constant flow of information. The need to understand what is true and what is not is important. The flipped classroom (翻转课堂) has already completely changed lecture-based lessons. It presents interesting content to students before they even come to class. They can access the Internet as many times as they want to review the lessons.

8 . During the cool months from October to March, camel caravans (骆驼车队)arrive in the desert city of Timbuktu (廷巴克图)every few days. Led by Tuareg and Arab traders, the caravans have traveled from the salt mines of Taoudenni in Mali.     1     Long ago people in the deserts of Africa could not get it easily. Salt was so valuable that 1 ounce of salt was worth 1 ounce of gold.

Nowadays, each salt caravan has from 60 to 300 Camels. Each Camel carries four to six bars of salt. The journey from the mines to Timbuktu takes 15 days.     2    

At Taoudenni, salt is mined from ancient lake-beds that dried up millions of years ago. The mines lie deep below the Earth’s surface and are reached by tunnels. Large blocks of salt are dug out and then cut into small blocks above ground.     3    The local people of the Bella and Haratin groups do the work. However, their wages are so low that they are treated little better than slaves.

    4     Here the salt is sold and carried downriver to other parts of West Africa. So Timbuktu is an important meeting place for the desert travelers. It was also once a center of education, with schools and a university that drew scholars from all of the world.

Trucks are taking the place of camels carrying salt. One truck can carry hundreds of bars of salt. And a truck can make the 900-mile round trip in about a week.     5    

9 . When almost everyone has a mobile phone, why are more than half of Australian homes still paying for a landline (座机)?

These days you’d be hard pressed to find anyone in Australia over the age of 15 who doesn’t own a mobile phone. In fact plenty of younger kids have one in their pocket. Practically everyone can make and receive calls anywhere, anytime.

Still, 55 percent of Australians have a landline phone at home and only just over a quarter (29%) rely only on their smartphones according to a survey (调查). Of those Australians who still have a landline, a third concede that it’s not really necessary and they’re keeping it as a security blanket — 19 percent say they never use it while a further 13 percent keep it in case of emergencies. I think my home falls into that category.

More than half of Australian homes are still choosing to stick with their home phone. Age is naturally a factor (因素)— only 58 percent of Generation Ys still use landlines now and then, compared to 84 percent of Baby Boomers who’ve perhaps had the same home number for 50 years. Age isn’t the only factor; I’d say it’s also to do with the makeup of your household.

Generation Xers with young families, like my wife and I, can still find it convenient to have a home phone rather than providing a mobile phone for every family member. That said, to be honest the only people who ever ring our home phone are our Baby Boomers parents, to the point where we play a game and guess who is calling before we pick up the phone (using Caller ID would take the fun out of it).

How attached are you to your landline? How long until they go the way of gas street lamps and morning milk deliveries?

10 . A robot with a sense of touch may one day feel “pain”, both its own physical pain and sympathy for the pain of its human companions. Such touchy-feely robots are still far off, but advances in robotic touch-sensing are bringing that possibility closer to reality.

Sensors set in soft, artificial skin that can detect both a gentle touch and a painful strike have been hooked up to a robot that can then signal emotions, Asada reported February 15 at the annual meeting of the American Association for the Advancement of Science. This artificial “pain nervous system,” as Asada calls it, may be a small building block for a machine that could ultimately experience pain. Such a feeling might also allow a robot to “sympathize” with a human companion’s suffering.

Asada, an engineer at Osaka University, and his colleagues have designed touch sensors that reliably pick up a range of touches. In a robot system named Affetto, a realistic looking child’s head, these touch and pain signals can be converted to emotional facial expressions.

A touch-sensitive, soft material, as opposed to a rigid metal surface, allows richer interactions between a machine and the world, says neuroscientist Kingson Man of the University of Southern California. Artificial skin “allows the possibility of engagement in truly intelligent ways”.

Such a system, Asada says, might ultimately lead to robots that can recognize the pain of others, a valuable skill for robots designed to help care for people in need, the elderly, for instance.

But there is an important distinction between a robot that responds in a predictable way to a painful strike and a robot that’s able to compute an internal feeling accurately, says Damasio, a neuroscientist also at the University of Southern California. A robot with sensors that can detect touch and pain is “along the lines of having a robot, for example, that smiles when you talk to it,” Damasio says. ‘It’s a device for communication of the machine to a human.” While that’s an interesting development, “it’s not the same thing” as a robot designed to compute some sort of internal experience, he says.
