I can't think of a better way of appreciating a new culture than by taking part in one of its festivals. You'll find that some festivals are celebrated by an entire country, while others may be known only to a single city or region, but either way festivals play an important role in a certain culture. Just enjoy them!

★ Tomatina — Bunol, Spain

    Every last Wednesday in August, the town of Bunol is filled with tons of tomatoes in the world's biggest food flight. Many people wear goggles (护目镜) during this hour of great fun, as the town becomes a red river.

★ Boryeong Mud Festival — Boryeong, South Korea

    For two weeks in July, millions gather in Boryeong to experience the grey pools and slides. What began as a way to help sell the region's mineral-rich mud has turned into a festive party with music and fireworks. The mud is usually only available in cosmetic products (化妆品), but here you can cake yourself in grey as you want.

★ Holi — India

    Holi, the Festival of Colors, is a Hindu celebration full of joy and one of India's most important holidays. During the day of the last full moon of the lunar month, usually late February or early March, the air is full of brightly colored powder (粉末). The festival is celebrated differently throughout the country, with bonfires and music, but the cheerful spirit is common among Hindu people around the world.

★ International Pillow Fight Day — Worldwide

    Tens of thousands of people took part in the 4th annual International Pillow Fight Day on April 2, 2013. From London to Vancouver to many other cities, the festival is held in more than 100 countries. So just bring a soft pillow in early April, and watch feathers fly.

    When we see well, we do not think about our eyes very often. It is only when we cannot see perfectly that we realize how important our eyes are.

    People who are near-sighted can only see things that are very close to their eyes. Everything else seems ­­blurry. Many people who do a lot of work, such as writing, reading and sewing become near-sighted. People who are far-sighted suffer from just the opposite problem. They can see things that are far away, but they have difficulty in reading a book unless they hold it at arm's length. If they want to do much reading, they must get glasses, too.

    Other people do not see clearly because their eyes are not exactly the right shape. They have what is called astigmatism (散光). This, too, can be corrected by glasses. Some people's eyes become cloudy because of cataracts (白内障). Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them.

    Having two good eyes is important for judging distances. Each eye sees things from a slightly different angle. To prove this to yourself, look at an object out of one eye; then look at the same object out of your other eye. You will find the object's relation to the background and other things around it has changed. The difference between these two different eye views helps us to judge how far away an object is. People who have only one eye cannot judge distances as people with two eyes.

A Guide to the University

    Food

    The TWU Cafeteria is open 7am to 8pm. It serves snacks, drinks, ice cream bars and meals. You can pay with cash or your ID cards. You can add meal money to your ID cards at the Front Desk. Even if you do not buy your food in the cafeteria, you can use the tables to eat your lunch, to have meetings and to study.

    If you are on campus in the evening or late at night, you can buy snacks, fast food, and drinks in the Lower Café located in the bottom level of the Gouglas Centre. This area is often used for entertainment such as concerts, games or TV watching.

Relaxation

    The Globe, located in the bottom level of McMillan Hall, is available for relaxing, studying, cooking, and eating. Monthly activities are held here for all international students. Hours are 10 am to 10 pm, closed on Sundays.

Health

    Located on the top floor of Douglas Hall, the Wellness Centre is committed to physical, emotional and social health. A doctor and nurse is available if you have health questions or need immediate medical help or personal advice. The cost of this is included in your medical insurance. Hours are Monday to Friday, 9am to noon and 1:00 to 4:30pm.

Academic Support

    All students have access to the Writing Centre on the upper floor of Douglas Hall. Here, qualified volunteers will work with you on written work, grammar, vocabulary, and other academic skills.

    The TWU Express is a shuttle service. The shuttle transports students between campus and the shopping centre, leaving from the Mattson Centre. Operation hours are between 8am and 3pm. Saturdays only. Round trip fare is $1.

    Volunteering abroad is a great way to help others, improve your skills and become a more confident, independent person. If you are interested in volunteering abroad, here are some places to go.

    Australia

    If you seek a life on the beach, in a great climate with friendly people, Australia might be your best bet. With thousands of volunteers already signing up to leave for Australia during the holidays, it will be a very popular option.

    Brazil

    This vast country has some great opportunities on offer and is especially popular this year. A lot of volunteer work is available in Brazil centers on conservation and ecological projects. With the world's largest rainforest in Brazil, of which huge part is in danger, there are lots of different jobs you can do.

    Kenya

    Kenya is the destination for those seeking an African experience. Generally volunteers in Kenya work in orphanages (孤儿院) or with local children living in slums (贫民窟). There is a great demand for volunteers in Africa because many people live in poverty, so if you truly feel like making a difference to a community, Kenya should be at the top of your list.

    Costa Rica

    Golden sandy beaches, clear coastlines and beautiful cities are what Costa Rica is all about. Because of its small size, you can see a lot of the country in just a short time. You can really make the most of your time as a volunteer. A lot of work is needed with wildlife and ecological work, so if you want to look after turtles (海龟) on the beach, Costa Rica could be just the place for you.

    Two heads are better than one. After all, when trying to make decisions, it's good to have a second opinion. But what about a third, fourth — even twelfth? What group size is best for making decisions quickly? For ants, four to six heads surpass one and also outperform 12 or 24. That's what Sylvia Zamescu now reports.

    The 18-year-old senior at Catalina Foothills High School in Tucson, Arizona isn't generally into ants. She's interested in decision-making, especially by people. Last summer, Sylvia read that social insects such as ants and bees can be used to model decision-making. Ants, for example, forage for food. When an ant finds it, it takes a bite and heads back to the nest. On the way; the ant leaves a scented trail for other ants to pick up. Back at the nest, the ant vomits up its meal into the mouth of other ants. Those nest-mates then decide with the first ant whether the food is good enough to deserve a trip back for more. If it is, they follow the first ant's scented trail to lunch.

    When there are too few ants, it could take a long time for one ant to spread the word. If there are too many, it's hard to "tell" each about the find. What's the right number for foraging success? Sylvia decided to find out. She contacted professors at the University of Arizona in Tucson to look for someone who would let her study decision-making by ants in their lab. Professor Wulfila Gronenberg answered her email.

    Working with one of Wulfila's graduate students Sylvia set up an experiment. She tested the behavior of one, two, four, six, twelve and twenty-four ants. Each group was placed in a large box al taped "starting line". At the other end of the box were two bricks of sweetened gelatin (动物胶) one contained only 3 per cent sugar, and the other 30 per cent. Sylvia timed how long it took each group of ants to find the food. She also measured how much time they spent around each sweet treat.

    When there were just one or two ants, the discovery was slow. The same was true when she set twelve or twenty-four ants loose. But four to six ants? Perfect! These medium-size groups found the food forest. They also figured out quickly that the sweeter food was better.

    Similar work has been done on bighorn sheep, fish and fruit flies. "It may not be four to six animals, but it's the same principle," Sylvia says. A medium-size group "is optimal". So when faced with a new decision, two heads are better than one. But too many heads are too much. Like the ants, a good decision may just require a happy medium.

Here are four books recommended by one of the most respected editors from Reader's Digest. If you have time to dip yourselves into the books, they can surely offer much food for thought.

Face It

Debbie Harry

HARPERCOLLINS

Picture this: it's the late 1970s and the punk music scene is starting to take hold. The band releases the album ParallelLines, which becomes the greatest hit. Everyone wants to attend her concert and some teenage girls even dream to be her. Now 75, Harry bares all about herself in Face It, starting from her childhood. Part shocking, this book is as humorous, moving and vigorous as its subject.

Scatterbrain

Henning Beck

NEWSOUTHBOOKS

If there is no obvious connection among what we see, the brain will substitute in the rest of the information without you even noticing, Beck says in the chapter Memory. In this "user's guide for your brain", he argues that mistakes are the keys to success. He combines science with brain-boosting advice and real-life stories to take the reader on a fascinating adventure through human memory.

You're Not Listening

Kate Murphy

PENGUINERANDOM HOUSE

When was the last time you listened to someone? Really listened without thinking about what you wanted to say next? And when was the last time someone really listened to you? Compared with talking, listening isn't considered so important, argues journalist Kate Murphy, but she insists it is actually the more powerful position in communication. Her insights could transform your conversations, your relationships and your life.

The Right-Brain Work Out

Russel Howcroft with Alex Wadelton

PENGUIN

In 1968,1600 five-year-olds were given a creativity test. They were retested at ages 10 and 15 and their scores were compared against adults. While 98 per cent of five-year-olds were assessed in the "highly creative" range (genius level), only two per cent of adults could be considered "highly creative". In The Right-Brain Work Out, the authors promise to re-train your brain to be more creative, using 70 questions to challenge you.
