【推荐2】When British musician Paul Barton performs in Lopburi lately, his energetic listeners react wildly. Some pull his hair or jump on his piano. Others steal his music. These behaviors are normal; however, these crowds are truly wild—wild monkeys to be exact, who are Barton’s latest animal fans. Past wildlife audiences included elephants and deer living in special protected areas. He also once played to cows to please them to get more milk.

Barton plays often to the animals in Lopburi, an area known for wild macaque monkeys. The pianist hopes the music shows bring calmness to the animals, which often suffer hunger during the hard time and become aggressive（好斗的）.The limited tourism means fewer people come to see the monkeys and feed them.“On the one hand, we need to make an effort to make sure that they eat correctly. On the other hand, we should try to calm these wild animals down,” said Barton, 59, a Thailand man.

Barton has played at four places in Lopburi, including an ancient Hindu temple, a store and an old movie theater. The animals quickly surround Barton when he plays music. Some of the creatures sit on his chair, while others climb up his body and touch his head. However, Barton keeps his attention on his performance, even when some animals run over his hands on the instrument and other animals take control of his music papers. Barton is happy to find they are curious about him and the piano and enjoy the music as he is playing it.

Typically, conservationists do this from low-flying planes in order to count and monitor African elephants, a method that takes many hours. With the new technique that combines satellite imagery with artificial intelligence, up to 3,100 square miles can be surveyed on a single blue-sky day in minutes. Then, the deep-learning computer analyzes those images and pick out individual elephants.

The new technique is a key part of ensuring the survival of the endangered species. Due to illegal hunting and habitat destruction, just 415,000 African elephants are living in the wild. “Accurate monitoring is essential if we’re to save the species,” said Olga Isupova, a computer scientist at the University of Bath in the UK. “We need to know where the animals are and how many there are.”  

What really makes this study stand apart from other satellite-tracking projects is how successful the computer program is at picking out the elephants from their complex backgrounds, including grasslands and partially tree-covered landscapes. Satellite imagery is also a much more efficient survey method than the current flyover surveys carried out, which is faster and avoids double-counting the same elephants. The remote survey also reduces the impact researchers have on the animals and allows them to count individuals moving between countries. 

“Although this is a proof of concept, it’s ready to go,” said professor Duporge, a zoologist at the Oxford University. “And conservation organizations are already interested in using this to replace surveys using aircraft. As satellite imaging improves, other smaller species may soon be able to be counted in greater detail from space too. ”

For the couple themselves, however, this “materially perfect world” was lacking in something—so now they are giving up all their possessions to travel around the world with their children. Most of their belongings have been given to their neighbors. Faye said, “It is a relief to get rid of so many possessions. Thankfully, our parents understand and support us.”

“I hesitated for a while because some friends think Faye and I are mad to give up so much. When we told the older boys, they were so excited that they were going to have so much time as a family. It made me realize the amount of toys or material possessions can’t replace time spent with our children. They’ve had to give away so many toys, bikes and books. My wife Faye was so determined to keep to our plan,” said Matthew.

They will leave this month and plan to start their travels in Sweden where they have friends. Faye said, “My older boys plot where we go next but we hope to see Europe and over two years travel as far as Japan, America, Bali and Thailand. We don’t plan to hire any tour guides. We just depend on a compass and local people to move in the right direction.”

Faye, who posts on Instagram as a mother of five boys, added, “It is a risk because we are giving up so much. I, however, even plan to quit my job after the travel. We can’t wait to spend more time with our sons without the stresses of everyday routines. We don’t know what will happen, but we do know if we didn’t do this we would always regret it.”

It came from a team that had been working all night to draft Beethoven’s unfinished 10th Symphony. The e-mail contained hundreds of versions, and Werzowa listened to them all, looking for the perfect tune—a sound that was unmistakably Beethoven. But the phrases he was listening to weren’t composed by Beethoven. They were created by artificial intelligence.

When Ludwig van Beethoven died in 1827, he left behind some musical drafts and notes. There was barely enough to make out a phrase, let alone a whole symphony. But that didn’t stop people from trying.

Werzowa and a group of music experts and computer scientists teamed up to use machine learning to create the symphony. Ahmed Elgammal led the AI side of the team. The team’s first task was to teach the AI to think like Beethoven. To do that, they gave it Beethoven’s complete works, his drafts and notes. They taught it Beethoven’s process—like how he went from four notes to his entire Fifth Symphony. Then they taught it to compose a bridge between two sections. With all that knowledge, the AI came as close to thinking like Beethoven as possible. But it still wasn’t enough. The AI doesn’t really produce something that can continue for a long time and be consistent. So the team had to put the selected pieces together to build a symphony.

Matthew Guzdial researches creativity (创造力) and machine learning at the University of Alberta. He didn’t work on the Beethoven project, but he says, “Modern AI, modern machine learning, is all about just copying small local patterns. And it’s up to a human to then take what the AI outputs and find the genius (天资). The genius wasn’t in the AI. The genius was in the human who was doing the selection.”

When I was a little girl, I spent memorable holidays with my grandmother, who lived in a small village. She was a farmer with a stooped (弯曲的) back that made it seem like she was always leaning forward to examine something. Early in the morning, she would tie a cloth around her waist and set out to the farm. I would skip breathlessly alongside, trying to keep up. On our way, she would greet everyone we passed.

There was the standard greeting, “Did you wake up on the right foot this morning?” Then, the more personalized greetings. To Patriarch Kosi who sat under the mango tree, she would ask, “Are the grandchildren in good health?” To the Bean Stew Seller who was preparing to serve breakfast, she would inquire, “Are your boys well?”

Sometimes, the greetings were spoken soothingly (安慰地). When we walked past the widow, Dada Mawusi, many months after her husband’s death, Grandmother would say directly, “How is your grieving?” She didn’t like to beat around the bush. The greeting made more sense to her to acknowledge the woman’s suffering, and in doing so, empathize (理解) with her.

The people that Grandmother greeted would respond similarly. “I see you have your granddaughter with you today. How is her father?” or “I see you have woken up before the cock’s crow today. May it be a fruitful day at the farm.” As a young girl, I thought these greetings were unnecessarily time-consuming. What I now realize is that the greetings increased a sense of belonging. My grandmother taught me that there is always time to greet someone before getting down to business. You can always take a few extra seconds to say a greeting to a person. We enrich our society when we acknowledge the unique presence of one another.
