Samuel Osmond is a 19-year-old law student from Cornwall, England. He never studied the piano. However, he can play very difficult musical pieces by musicians such as Chopin and Beethoven just a few minutes after he hears them. He learns a piece of music by listening to it in parts. Then he thinks about the notes in his head. Two years ago, he played his first piece Moonlight Sonata (奏鸣曲) by Beethoven. He surprised everyone around him.

    Amazed that he remembered this long and difficult piece of music and played it perfectly, his teachers say Samuel is unbelievable. They say his ability is very rare, but Samuel doesn't even realize that what he can do is special. Samuel wanted to become a lawyer as it was the wish of his parents, but music teachers told him he should study music instead. Now, he studies law and music.

    Samuel can't understand why everyone is so surprised. “I grew up with music. My mother played the piano and my father played the guitar. About two years ago, I suddenly decided to sun playing the piano, without being able to read music and without having any lessons. It comes easily to me — I hear the notes and can bear them in mind — each and every note,” says Samuel.

    Recently, Samuel performed a piece during a special event at his college. The piece had more than a thousand notes. The audience was impressed by his amazing performance. He is now learning a piece that is so difficult that many professional pianists can't play it. Samuel says confidently,” It's all about super memory — I guess I have that gift.”

    However, Samuel's ability to remember things doesn't slop with music. His family says that even when he was a young boy, Samuel heard someone read a story, and then he could retell the story word for word.

    Samuel is still only a teenager. He doesn't know what he wants to do in the future. For now, he is just happy to play beautiful music and continue his studies.

    Never before have Chinese Internet users so openly liked and supported a Japanese athlete as they have loved table tennis star Ai Fukuhara (福原爱), better known by her Japanese nickname “Ai-Chan”.

    But they may now feel heartbroken, as the 29-year-old said on Oct.21 that she would retire (退役) from the sport. I've found the answers within myself that I have been searching for. From the standpoint ( 立场) of an athlete, I'm drawing the line here," Fukuhara wrote on her blog.

    After she started playing table tennis at 3 years old, Fukuhara was seen as a child gifted at the sport. Being trained in China at a very young age, Fukuhara can speak fluent Mandarin, with a northeastern accent.

    If her deep-rooted connection with China is one thing that has won the hearts of Chinese fans, her character is another. She always shows her real self to the public without hiding her feelings. She laughs in games when she wins, and cries when she loses. The fact that she often cries when she gets upset has earned her the nickname “Crybaby Ai-Chan” in China.

    Although she was beaten by a long line of Chinese players, Fukuhara always tries her best when playing her favorite sport. Yet, she also knows that now is the best time to close the curtain on her successful career. It's hard to say goodbye to a long journey but as Fukuhara once said on a reality TV show, “Life is not all about table tennis. Instead, it is just part of life.”

    As for her future plans, Fukuhara wrote that she would like to help more people around the world get to know the beauty of the sport.

    Our mother earth is going through a very tough situation and we, the entire human race, are destroying our environment or unconsciously without even realizing its consequences. Now we have to act very smartly and plan something to sustain what we still have, getting all necessary support from nature to lead healthy lives.

    Gardening is always an excellent and environmentally friendly idea. If you can go for sustainable gardening, then it will be even more useful for all. Gardening is a favorite hobby for many. It is time to channelize your hobby towards a more meaningful motivation.

    When we do gardening we need to use different ingredients (材料) to grow plants. Some of them are natural resources like water, soil, sunshine, and many things like this. Using these resources smartly is a part of sustainable gardening. Some simple techniques include: use less water and organic things to grow plants; try to store rainwater so that you can use them for gardening; try using less energy to drive devices; avoid using plastics in any form while gardening; reuse the leaves from your garden to fertilize them. These are the basic sustainable measures. To do so we need to have proper knowledge about gardening and its requirements so that we can use proper resources without wasting any of them.

    In today's busy life we don't get much time to spend on our environment. Gardening gives us a chance to do so. We can also have some pesticide-free (无农药的) and fresh food if we grow them in our garden. This is the right time to do some good to protect our own environment and gardening is one of the easiest ways. Do you want to start gardening, but you're not sure how?

    As Artificial Intelligence(AI) becomes increasingly sophisticated(复杂的), there are growing concerns that robots could become a threat. This danger can be avoided, according to computer science Professor Stuart Russell, if we figure out how to turn human values into a programmable code.

    Russell argues that as robots take on more complicated tasks, it's necessary to translate our morals into AI language.

    For example, if a robot does chores around the house, you wouldn't want it to put the pet cat in the oven to make dinner for the hungry children. "You would want that robot preloaded with a good set of values," said Russell.

    Some robots are already programmed with basic human values. For example, mobile robots have been programmed to keep a comfortable distance from humans. Obviously there are cultural differences, but if you were talking to another person and they came up close in your personal space, you wouldn't think that's the kind of thing a properly brought-up person would do.

    It will be possible to create more sophisticated moral machines, if only we can find a way to set out human values as clear rules.

    Robots could also learn values from drawing patterns from large sets of data on human behaviour. They are dangerous only if programmers are careless.

    The biggest concern with robots going against human values is that human beings fail to so sufficient testing and they've produced a system that will break some kind of taboos(禁忌).

    One simple check would be to program a robot to check the correct course of action with a human when presented with an unusual situation.

    If the robot is unsure whether an animal is suitable for the microwave, it has the opportunity to stop, send out beeps(嘟嘟声), and ask for directions from a human. If we humans aren't quite sure about a decision, we go and ask somebody else.

    The most difficult step in programming values will be deciding exactly what we believe in moral, and how to create a set of ethical rules. But if we come up with an answer, robots could be good for humanity.
