Still seeking a destination for your weekend break? There are some places which are probably a mere walk away from your college.

King's Art Centre

    A day at the Centre could mean a visit to an exhibition of the work of one of the most interesting contemporary artists on show anywhere. This weekend tees the opening of an exhibition of four local artists.

You could attend a class teaching you how to 'learn from the masters' or get more creative with paint —- free of charge.

    The Centre also runs two life drawing classes for which there is a small fee.

The Botanic Garden

    The Garden has over 8,000 plant species; it holds the research and teaching collection of living plants for Cambridge University.

    The multi-branched Torch Aloe here is impressive. The African plant produces red flowers above blue-green leaves, and is not one to miss.

    Get to the display house to see Dionaea muscipula, a plant more commonly known as the Venus Flytrap that feeds on insects and other small animals.

    The Garden is also a place for wildlife-enthusiasts. Look for grass snakes in the lake. A snake called 'Hissing Sid' is regularly seen lying in the heat of the warm sun.

Byron's Pool

    Many stories surround Lord Byron's time as a student of Cambridge University, Arriving in 1805, he wrote a letter complaining that it was a place of "mess and drunkenness". However, it seems as though Byron did manage to pass the time pleasantly enough. I'm not just talking about the pet bear he kept in his roans. He spent a great deal of time walking in the village.

It is also said that on occasion Byron swam naked by moonlight in the lake, which is now known as Byron's Pool. A couple of miles past Grantchester in the south Cambridgeshire countryside, the pool is surrounded by beautiful circular paths around the fields. The cries of invisible birds make the trip a lovely experience and on the way home you can drop into the village for afternoon tea. If you don't trust me, then perhaps you'll take it from Virginia Woolf一—over a century after Byron, she reportedly took a trip to swim in the same pool.

    Even though it's not the most popular time of year to get married, I allow my thoughts to wander and consider the most unusual marriage habits across the world.

    In some parts of India it is believed that ghosts can stay with certain people of the living world. In general, girls who are born with a baby tooth and girls who are very ugly or have some facial damage are believed to be owned by ghosts. The only way to free from the ghosts is for the girl to marry an animal, typically a goat or a dog. She is free to marry a man later on, when the ghosts are proven to be freed from her. I wonder who makes this decision and how they come to their conclusion.

    In Korea, it is a custom for grooms to request that their successfully married friends carve them wooden ducks as a symbol of great marriage. Hand-carving a wooden duck can't be easy. This leads me to wonder why it's a duck and not another animal.

    Imagine being as young as 5 and already your parents are sending you to a fat farm where you are forced to eat too much food until you vomit (呕吐). Then, the old woman watching you eat forces you to eat that vomit. This is not a TV show. This is really happening in some parts of Africa. Men there want women fat; the fatter the better. It doesn't matter if it ruins their health or make them live shorter lives. All that matters is that the woman is as large as possible in order to sell her for a high price when she reaches the age for marrying.

    About 15 years ago, I taught A Problem from Hell, a book on genocides (大屠杀), to a group of 18- and 19-year-olds in a mid-west university in the US. In my class there was a young man who had spent his boyhood in Bosnia as NATO bombed his hometown. My other students, amazed by his connection to the genocide in the textbook, asked him what it was like to grow up in a war-zone. "A pretty normal childhood as you had here," he said. "We played cards inside a lot, and when there was no bombing we kicked a ball in the street."

    In the past few years, the world has seen a rapid increase in refugees (难民), with the number hitting 60 million. Viet Thanh Nguyen's story collection The Refugees reminds us that literature is news that stays news. Set in the Vietnamese communities in California as well as in Vietnam, the stories do not aim to surprise us with new twists or shock us with wonderful details, as war and refugee stories could easily choose to do. Rather, like the young man from Bosnia, Nguyen's characters tell these stories because they are the only ones known to them.

    Included in the collection are two of the most touching pieces, both about siblings (兄弟或姊妹) separated by geography and history. In "Black-Eyed Women", the narrator (讲述人), a young Vietnamese woman, is visited by the ghost of her elder brother, who died young on the boat when the family took flight from the war. The tale of love and loss, violence and violation, may not be unfamiliar to the reader, but the determination of the brother's ghost (he has taken decades to swim across the Pacific to reach America) and the sister's abandoning herself to a half death make the story lasting.

    As an echo, the closing story, "Fatherland", explores a more complex situation between two siblings. The narrator, a young Vietnamese woman, meets her half-sister, visiting from the US for the first time. Adding to the tension is the fact that her father has named the narrator and her siblings after his first set of children. Two sisters, one American and one Vietnamese, yet named the same by the father – it may sound strange, but isn't it the fate many refugees have to face: a life left behind, that could have been theirs; and a life in an adopted country.

    The theme of doubleness –  choice and inevitability (不可避免性), home and homelessness, starting afresh and being stuck – is present not only in the stories of Vietnamese refugees, but also of those who have become refugees from their own homes and loved ones. "Smiling at your relatives never got you very far, but smiling at strangers and acquaintances sometimes did." So a pilot, who fought in the Vietnam war and is now revisiting the country for the first time, thinks while waving at the locals from a tour bus. He's distant from his daughter, just as a Mexican American in the collection is distant from his wife, or a young man from Hong Kong is distant from his father.

    The collection is full of refugees, whether from external or from a deeper, more internal conflict between even those who are closest to each other. With anger but not despair, with reconciliation (和解) but not unrealistic hope, and with genuine humour that is not used to insult anyone, Nguyen has breathed life into many unforgettable characters.

    Modern day robots may not be as entertaining as R2D2 or the robot from Lost in Space, but robots are very important to space exploration and are being used in a variety of different ways for several important reasons.

    Robots make great explorers on planets, moons, and other landing areas. Aside from the earth, just about every surface in the solar system is unsafe for humans to explore. The air on most other planets is insufficient fortunate for humans to explore. The air on most other planets is insufficient for humans to breathe, making it necessary to wear a space suit and oxygen equipment. The temperatures on these surfaces are much too hot or much too cold for any humans to withstand. Plus there would be complications with radiation, weather, and a lack of gravity. Robots have much less limitation in these areas and can survive much longer under these conditions.

    Robots are designed for collecting scientific data. Robots are also able to perform many tasks at one time and can process information much quicker and more efficiently. Important scientific projects from detecting minerals, analyzing ground samples, to finding water are all performed much quicker and accurately by robots.

The use of robots has made the cost of space exploration much less expensive than it would cost for humans to do the work. In order to successfully send humans into space we would need to build a vehicle that can not only carry humans, but also enough | food and water to keep them alive for the duration of the trip. Moreover, robots have no problems working for hours on end. Robots never complain, they don't require food or water, and they never need a bathroom break.

    Over the past 30 years or so there have been many different types of robots used successfully in the exploration of space. Perhaps the most famous and successful robots are Spirit and Opportunity who have both been exploring the surface of Mars. They have both been very successful with experiments on soil and rocks and have even found evidence of water in Mars' history.

    Devon Gallagher, a college graduate from Philadelphia, wants the world to know exactly here she's been during her worldwide vacation in a special way.

    The traveler, who was born with a bone disease, had her right leg amputated(k)at the age of four. Although the amputation caused setbacks for Gallagher early on, she now sees it as nothing short of inspiration for living her best life.

    To spread that message, Gallagher has taken to social media, where she shares photos of her travels across the globe, but instead of simply using a geo-tag, she writes her location across her artificial leg before taking a picture.

    Now she has been taking pictures across the Continent, which show her cycling over the canal in Amsterdam relaxing on a wall overlooking the city of Barcelona, posing with a waffle in Brussels, taking in the spectacular Parthenon temple in Athens and enjoying a river cruise in Budapest, all with the well-known locations written on her artificial leg “I get a new leg every two years and I can choose the design on it. One day I had a sudden thought to get a chalk-board, "Gallagher said. "My mum and grand-mother weren't too keen on the idea, but my friends thought it was great and told me to go for it, so I did.”

    Gallagher said people often stare when she's writing on her leg, but once she shares the photos she receives only positive feedback. "My leg hasn't stopped me from doing anything I've wanted to do," she said. "I don't know if it's my determination to prove to myself that I can do it, but regardless, I've been able to keep up with my peers and lead a pretty great life, Gallagher shows us that you should never let anything stand in the way of your dreams. And if life gives you an artificial leg, make art

    It all started in 2007 when James Bowen, a thirty­something drug addict who survived by playing guitar on the street, found an orange cat sitting in front of the door of his apartment.

    Bowen noticed the cat was wounded. Without hesitation, the young man took him to the Humane Society and spent the little money he had on medicine to heal him.

    Shortly thereafter, the cat, who was healing and feeling much better, began to follow the musician when he left the house. Then one day the cat got on the bus that Bowen took to the place where he worked.

    That's how the cat, who had recently been named Bob, began to accompany his human friend to his musical performances. Bob's mere presence attracted the attention of passers­by. He and Bowen would finish off each song with a high five. Pretty soon, the images of Bob wearing a scarf while sitting on the musician's shoulder, or keeping him company while he played the guitar, began to go viral all over the world.

    Eventually, the news found out about the pair and did a story for the magazine Islington Tribune. It was not long after that when a book agent appeared in their lives and gave them a chance to tell their story.

    By then, Bowen, who had managed to get away from drugs, wrote a novel called A Street Cat Named Bob. He related in great detail how meeting the cat changed him.

    The book soon sold more than six million copies and even spread beyond the borders of the United Kingdom. In fact, it was translated into thirty languages.

    Through all of these changing circumstances, Bob has always been with Bowen—on his shoulder.

    You can't make up a story like this. But life always gives opportunities to those who know how to get hold of them. So if you are ever in a position where a cat has chosen you, don't ignore it. You can't imagine all the good that life may have in store if you decide to accept the proposal.
