"If you want to see a thing well, reach out and touch it!"

That may seem a strange thing to say. But touching things can help you to see them better.

    Your eyes can tell you that a glass ball is round. But by holding it in your hands, you can feel how smooth and cool the ball is. You can feel how heavy the glass is. When you feel all these about the ball, you really see it. With your skin, you can feel better. For example, your fingers can tell (辨别) the difference between two coins in your pocket. You can feel a little drop of water on the back of your hand, too. You can even feel sounds against your skin. Have you ever wanted to know why some people like very loud music? They must like to feel the sounds of music.

    All children soon learn what "Don't touch!" means. They hear it often. Yet most of us keep on touching things as we grow up. In shops, we touch things we might buy: food, clothes. To see something well, we have to touch it. The bottoms of our feet can feel things, too. You know this when you walk on warm sand, cool grass or a hard floor. All feel different under your feet.

    There are ways of learning to see well by feeling. One way is to close your eyes and try to feel everything that is touching your skin. Feel the shoes on your feet, the clothes on your body, the air on your skin. At first, it is not easy to feel these things. You are too used to them!

    Most museums are just for looking. But today some museums have some things to touch. Their signs say, "Do touch!" There you can feel everything on show.

    If you want to see better, reach out and touch. Then you will really see!

    If you could be anybody in the world, who would it be? Your neighbour or a super star? A few people have experienced what it might be like to step into the skin of another person, thanks to an unusual virtual reality（虚拟现实）device. Rikke Wahl, an actress, model and artist, was one of the participants in a body swapping experiment at the Be Another lab, a project developed by a group of artists based in Barcelona. She swapped with her partner, an actor, using a machine called The Machine to Be Another and temporarily became a man. "As I looked down, I saw my whole body as a man, dressed in my partner's pants," she said. "That's the picture I remember best."

    The set-up is relatively simple. Both users wear a virtual reality headset with a camera on the top. The video from each camera is sent to the other person, so what you see is the exact view of your partner. If she moves her arm, you see it. If you move your arm, she sees it.

    To get used to seeing another person's body without actually having control of it, participants start by raising their arms and legs very slowly, so that the other can follow along. Eventually, this kind of slow synchronised（同步的）movement becomes comfortable, and participants really start to feel as though they are living in another person's body.

    Using such technology promises to alter people's behaviour afterwards-potentially for the better. Studies have shown that virtual reality can be effective in fighting racism-the bias（偏见）that humans have against those who don't look or sound like them. Researchers at the University of Barcelona gave people a questionnaire called the Implicit Association Test, which measures the strength of people's associations between, for instance, black people and adjectives such as good, bad, athletic or awkward. Then they asked them to control the body of a dark skinned digital character using virtual reality glasses, before taking the test again. This time, the participants' bias scores were lower. The idea is that once you've "put yourself in another's shoes" you're less likely to think ill of them, because your brain has internalised the feeling of being that person.

    The creators of The Machine to Be Another hope to achieve a similar result. "At the end of body swapping, people feel like holding each other in their arms," says Arthur Pointeau, a programmer with the project. "It's a really nice way to have this kind of experience. I would really, really recommend it to everyone."

    One day an out-of-work mime(哑剧演员)is visiting a zoo and attempts to earn some money as a performer. As soon as he starts to draw the crowd, a zoo keeper grabs him and drags him into his office. The zoo keeper explains to the mime that the zoo's most popular attraction, a gorilla, died suddenly and the keeper fears that the attendance at the zoo will fall off. He offers the mime a job to dress up as the gorilla until they can get another one. The mime accepts.

    So the next morning the mime puts on the gorilla suit and enters the cage before the crowd comes. He discovers that it's a great job. He can sleep when he wants to, play and make fun of people and he draws bigger crowds than he ever did as a mime. However, eventually the crowds get tired of him and he doesn't like just swinging on wires any longer. He begins to notice that the people are paying more attention to the lion in the cage next to his.

    Not wanting to lose the attention of his audience, he climbs to the top of his cage, crawls across a partition(隔开物), and dangles(悬荡) from the top of the lion's cage. Of course, this makes the lion furious, but the crowd loves it. At the end of the day the zoo keeper comes and gives the mime a raise for being such a good attraction. Well, this goes on for some time, the mime keeps laughing at the lion, the crowds grow larger, and his salary keeps going up.

    Then one terrible day when he is dangling over the furious lion he slips and falls. The mime is terrified. The lion gathers its strength and prepares to pounce(猛扑). The mime is so scared that he begins to run round and round in the cage with the lion close behind. Finally, the mime starts screaming and yelling, "Help me! Help me!", but the lion is quick and pounces. The mime soon finds himself lying on his back looking up at the angry lion and the lion says, "Shut up, you idiot! Do you want to get us both fired?"

    Discovering Tasmania

    The island of Tasmania a place of natural beauty and has more than 2,000 km of walking tracks and 18 national parks. If you go on a tour, you'll discover a wild and beautiful place where the people are friendly and the food is delicious. If you don't like walking, there are other tours you can choose from including a river cruise(巡游) and cycling. You can also enjoy fishing, sailing or sunbathing on the beach.

    The Tarkine coast is located in the northwest of Tasmania. It's such a wild and remote(偏僻) area that you can easily complete your walk without seeing anyone apart from the members of your group and your two guides. The area contains the largest rainforest in Australia which is home to more than 50 endangered species. It is also home to many Aboriginal Heritage Sites. During your tour, you'll come across rivers, mountain ranges, waterfalls, wildlife and long wild beaches.

    Tour Itinerary：

    Day 1：

    You're picked up from your hotel in Launceston and driven to the Tarkine. You then complete a three­hour walk through the forest before arriving at your camp at Mystery Creek. There you will enjoy a delicious meal cooked by your guides.

    Who could have imagined that a treadmill(跑步机)on wheels would one day become a thing? Lopifit is an unusual means of transportation that allows you to power an electric bicycle by walking on a treadmill.

    Lopifit founder Bruin Bergmeester says it all started when he asked himself the question. "How can I use a treadmill outdoors?" He eventually came up with a design, to which he added an electric engine, and Lopifit was born. The treadmill bicycle is similar to a typical electric bicycle in that the motor only works when the rider puts power in as well. The Lopifit senses it when you walk on the treadmill and uses the motor to turn a drive chain at the back part of the treadmill, helping you reach a top speed of 17 miles per hour.

    To use the Lopifit, simply turn on the battery and use your feet to slide the treadmill backwards and activate (激活) the motor. Then get on and enjoy the ride! If you need speed, just walk on the treadmill, and if you want to coast, all you have to do is stay still and admire the view. To stop, you have two hand brakes available.

    The Lopifit first hit the streets in 2014 and, unsurprisingly, became an instant hit. That was actually quite challenging for the company, because it started get inquiries and calls for orders, but it was nowhere near ready for mass production. The unique treadmill bicycle became available this year, and Lopifit is struggling to keep up with demand, despite the high price tag of $ 2,115.

    But despite having a very loyal fan-base of so-called Lopifitters, the creative means of transportation also has naysayers who simply consider the invention stupid and unnecessary. They basically believe that if you're going to walk, you might as well do it the old-fashioned way. But the Lopifit does have the unique advantage of helping you walk really fast without breaking a sweat, or walking at cycling speed, if you will.

    The baby is just one day old and has not yet left hospital. She is quiet but alert (警觉的). Twenty centimeters from her face researchers have placed a white card with two black spots on it. She stares at it carefully. A researcher removes the card and replaces it by another, this time with the spots differently spaced. As the cards change from one to the other, her gaze(凝视) starts to lose its focus—until a third, with three black spots, is presented. Her gaze returns: she looks at it for twice as long as she did at the previous card. Can she tell that the number two is different from three, just 24 hours after coming into the world?

    Or do newborns simply prefer more to fewer? The same experiment, but with three spots shown before two, shows the same return of interest when the number of spots changes. Perhaps it is just the newness? When slightly older babies were shown cards with pictures of objects (a comb, a key, an orange and so on), changing the number of objects had an effect separate from changing the objects themselves. Could it be the pattern that two things make, as opposed to three? No again. Babies paid more attention to squares moving randomly(随意地)on a screen when their number changed from two to three, or three to two. The effect even crosses between senses. Babies who were repeatedly shown two spots became more excited when they then heard three drumbeats than when they heard just two; likewise(同样地) when the researchers started with drumbeats and moved to spots.
