Beethoven was born over 250 years ago, yet his music is still played daily around the world. Beethoven wrote many famous pieces of music, but he’s probably best known for his nine symphonies (交响曲). Before Beethoven died in 1827, he began a 10th Symphony, but never finished. What he left behind were some notes about the piece and a few “sketches” (草图) — short bits of written music.
In 2019, a special team of musicians, computer scientists, and historians was formed. Their goal: to try to complete Beethoven’s 10th Symphony to celebrate his 250th birthday. The team wanted to come as close as possible to producing the symphony that Beethoven meant to write.
The team trained an AI to help with the symphony. They turned every piece of music that Beethoven ever wrote into a form the computer could understand. By feeding the program all of Beethoven’s music, the AI could look for the way Beethoven wrote. Other members of the team studied Beethoven’s notes and sketches, and attempted to find out what Beethoven was planning to do.
One early test told the team they were on the right track. They took a few minutes of music created by the AI based on Beethoven’s sketches, and played it for Beethoven experts, musicians, and reporters. No one could tell which parts had been written by Beethoven and which parts the AI made up. Finally, the AI connected the little musical bits into a symphony. It took the team over two years to complete Beethoven’s 10th Symphony-40 minutes’ music.
So Beethoven now has a 10th Symphony. And though Beethoven didn’t write it all, the team feels sure that the music is very much like what he might have written, if he’d had the chance.

【推荐2】“What is the story of your piano?” A new friend asked over dinner. My piano stays in a corner of small living room. “All pianos have stories,” she said. Suddenly, my piano’s story came flooding out of me fully-formed as if I’d always had this tale to tell.
I loved music since childhood. I studied with the recorder and moved to the violin, trumpet and guitar. But playing the piano had always been my dream, a dream our family could not afford.
I grew up in an immigrant Chinese family in Toronto. My father waited tables in a Chinese restaurant, and my mother worked in a Chinese laundry. Despite our poor childhood, my siblings (兄弟姐妹) and I were always fed with love. I can’t remember which birthday it was when my mother spared the money to buy me a doll. Of course, by then I’d outgrown wanting dolls. But she worked too hard to know that and I never told her. I happily and gratefully accepted the doll because I loved the gift that was her loving me enough to buy it for me.
So it was eventually with my piano. It was in my last year of high school. I took piano lessons for about a year before university forced me to stop. I had to make a decision to continue the more practical goal of medical school or my love for music. The practical one in me won. But I also stopped piano lessons because as with my doll, it was too late to learn to play the way I wanted.
I moved that piano around with me over the next decade — until my son was born, he showed an early interest in music, so I put him in piano lessons.
I’ve come to realize that in pursuit of my career, I’ve let all personal pleasure fall away. Maybe it’s time to get that piano retuned (重新调音) again, this time for myself, before it’s too late to enjoy. Maybe that’s something we all should do right now.
Sometimes a single question can open whole paths of thinking and discovery. So, what is the story of your piano?

【推荐1】Sending human travelers to Mars would require scientists and engineers to overcome a range of technological and safety obstacles. One of them is the severe risk caused by particle radiation (粒子辐射) from the sun, distant stars and galaxies (星系).
Answering two key questions would go a long way toward overcoming that obstacle: Would particle radiation cause too severe a threat to human life throughout a round trip to the red planet? And, could the very timing of a mission to Mars help protect astronauts and the spacecraft from the radiation?
In a new article published in the journal Space Weather, an international team of space scientists, including researchers from UCLA, answers those two questions with a “no” and a “yes”. That is, humans should be able to safely travel and from Mars if the spacecraft has sufficient protection and the round trip is shorter than approximately four years. And the timing of a human mission to Mars would indeed make a difference: The scientists determined that the best time for a flight to leave Earth would be when solar activity is at its peak, known as the solar maximum.
The scientists’ calculations demonstrate that it would be possible to protect a Mars-bound spacecraft from energetic particles from the sun because, during solar maximum, the most dangerous and energetic particles from distant galaxies are decreased by the strengthened solar activity.
A trip of that length would be imaginable. The average flight to Mars takes about nine months, so depending on the timing of launch and available fuel, it is reasonable that a human mission could reach the planet and return to Earth in less than two years, according to Yuri Shprits, a UCLA research geophysicist and co-author of the paper.
“This study shows that while space radiation imposes (强加) strict limitations on how heavy the spacecraft can be and the time of launch, and it presents technological difficulties for human missions to Mars, such a mission is practical,” said Shprits.

【推荐3】At the end of 2019, I learned that HereAfter AI, whose goal is to let the living communicate with the dead, was looking for applicants of its new AI project. Interested in what it was promising, I applied to experiment the software on my very-much-alive parents.
At first, I thought it would be just a fun project to see what was technologically possible. Then their health condition added some urgency to the experiment. I was frightened that my parents might die since my father had been diagnosed with cancer and my mother was recently developing symptoms of early Alzheimer’s disease, and that with the distance between us, I might never have the chance to say goodbye.
The first step was an interview. My parents were asked questions by a technician for hours — about everything from their earliest memories to what they believe will happen after they die. Whether through illness-generated concerns or a willingness to humor their daughter, my parents put up zero resistance. The company then took their responses and started to create the voice assistants. A few months later, my virtual parents arrived via email attachment.
When I communicated with them through the app on my phone, my hands were shaking. I hadn’t seen my actual, real parents for six months. They told me personal stories I’d never heard. They gave me life advice and told me things about their childhoods, as well as my own. It was mesmerizing.
Personally, I have mixed feelings about my experiment. I’m glad to have my virtual parents. They’ve enabled me to learn new things about my parents, and it’s comforting to think that those bots will be there even when my parents aren’t. On the other hand, I can’t help but find it sad that it took a stranger interviewing my parents for me to properly appreciate the complex people they are. But I feel lucky to have had the chance to grasp that — and to still have the precious opportunity to spend more time with them and learn more about them, face to face, no technology involved.

We often hear of the English "reserve"(矜持). On a long railway journey, with four Englishmen sitting together, often there won’t be a single word spoken during the whole journey. The English think it is a bad manner to ask personal questions. That wouldn’t be the case in America. In a short ride in New York, a taxi driver will tell you about himself, his wife and his family, and probably the towns of England he has visited, too.
The English value privacy (隐私) very much. An Englishman’s house usually has a small garden with a fence all around to separate it from the neighbors’. An Englishman’s house is his castle.
Finally, we have to refer to the most special feature of the Scottish (苏格兰的) people —the Scottish dress. Scotland is probably best known to the world for its traditional costume —the kilt. This short, skirt-like piece of clothing is worn by men.
The kilt is made of a special type of colorful cloth called tartan, which is very special in Scotland.

【推荐2】The traditional Chinese solar calendar divides the year into 24 solar terms. Start of Autumn, the 13th solar term of the year, begins this year on Aug.8 and ends on Aug.22. Start of Autumn reflects the end of summer and the beginning of autumn. The following are 4 things you should know about Start of Autumn.
“Autumn Tiger”
Although Start of Autumn indicates the beginning of autumn, hot weather will not come to an end. The period of hot days after Start of Autumn, usually lasting for 30 days, is called “Autumn Tiger” or “Indian Summer. ” Because of decreasing rainfall, it is even much hotter during this period than during Major Heat.
Fleshing out in autumn
On the first day of the Start of Autumn, usually people will weigh themselves and compare their weight to what it was at the Start of Summer. If one has lost weight during the summer, then at the beginning of autumn, he or she needs to flesh out by eating many different kinds of delicious food, especially meat.
Gathering crops
Start of Autumn is a big solar term for farmers. It is time to gather crops. There is a saying: If it rains on the day of the Start of Autumn, a good harvest is expected.
Eating peaches
In Hangzhou, people eat peaches on the Start of Autumn day. The peach stones are kept until New Year’s Eve and thrown into the stove, burned into ash. People believed that in this way, plagues (瘟疫) could be prevented for the whole year.

【推荐3】If you are in town in a western country, you will often see people walking with their dogs. It is still true that a dog is the most useful animal in the world, but the reason why one keeps a dog has changed.
Once upon a time, a man met a dog and wanted it to help him in the fight against other animals, and he found that the dog listened to him and did what he told it to. Later people used dogs for the hunting of other animals, and the dogs didn’t eat what they got until their masters agreed. So dogs were used for driving sheep and guarding chickens.
But now the people in the towns and cities do not need dogs to hunt other animals. Of course they keep them to frighten thieves, but the most important reason is that people feel lonely in the city. For a child, a dog is his best friend when he has no friends to play with. For a young wife, a dog is her child when she doesn’t have her own. For old people, a dog is also a child when their real children have grown up and left. Now people do not have to use a dog but they keep it as a friend, just like a member of the family.
