To learn new things, we must sometimes fail. But what's the right amount of failure? New research led by the University of Arizona proposes a mathematical answer to that question.
Educators have long recognized that there is something of a "sweet spot" when it comes to learning. That is, we learn best when we are challenged to grasp something just outside of our existing knowledge. When a challenge is too simple, we don't learn anything new; likewise, we don't expand our knowledge when a challenge is so difficult that we fail entirely or give up.
So where does the sweet spot lie? According to the new study, it's when failure occurs 15% of the time. Put another way, it's when the right answer is given 85%of the time.
Researchers at the University of Arizona came up with the so-called "85% Rule" after conducting a series of machine-learning experiments in which they taught computers simple tasks, such as classifying different patterns into one of two categories.
The computers learned fastest in situations in which the difficulty was such that they responded with 85% accuracy.
"If you have an error rate of 15% or accuracy of 85%, you are always maximizing your rate of learning in these two-choice tasks," said Professor Robert Wilson.
When we think about how humans learn, the 85%Rule would mostly likely apply to perceptual(感知的)learning, in which we gradually learn through experience and examples, Wilson said. Imagine, for instance, a radiologist(放射科医生)learning to tell the difference between images of tumors(肿瘤)and non-tumors.
"You need examples to get better at figuring out there's a tumor in an image, "Wilson said. "If I give really easy examples, you get 100% right all the time and there's nothing left to learn. You're not going to be taking as much from that as a situation where you are struggling a little hit. If I give really hard examples, you'll he 50% correct and still not learning anything new, while if I give you something in between, you can he at this sweet spot where you are getting the most information from each particular example."

【推荐1】Does adversity (逆境) warm hearts or harden them? Recently, my graduate student Daniel and I set out to explore the relationship between adversity and compassion (同情).
We conducted a study online and reached more than 200 people from all walks of life. After asking them about the hardships they faced and how often they experienced compassion, we offered them the chance to donate some of the money they were about to be paid for taking part in the study to help people in need. The result showed that those who had faced serious adversities in life feel more compassion for suffering people. And as a result, they donated more money.
Now, if experiencing any type of hardship can make a person more compassionate, you might assume that the compassion would be reached when someone has experienced the exact misfortune that another person is facing. Interestingly, this turns out to be dead wrong.
In an article recently published in the Journal of Personality and Social Psychology, the Kellogg School of Management professor Loran Nordgren and his team found that the human mind refuses to work as usual when it comes to remembering its own past hardships: it regularly makes them appear to be less painful than they actually were. Therefore, recalling a bad experience in your own past may make you underestimate (低估) the difficulty of others’ challenges. You overcame it, you think; so should he. The result? You lack compassion.
Our findings, taken together with those of Professor Nordgren and his team, are that living through hardships doesn’t either warm hearts or harden them; it does both. Knowing suffering in life usually enhances the compassion we feel for others, except when the suffering involves specific painful events that we know all too well.

【推荐2】A diet high in fats and sugars actually affects the parts of the brain that are important to memory and makes people more likely to desire for unhealthful food, says American psychologist Terry Davidson.
Davidson didn’t start out studying people’s eating. Instead, he was interested in learning about the hippocampus（海马体）, a part of the brain heavily involved in memory. He noticed something strange when he studied mice with hippocampal damage. They would go to pick up food more often than the others, but they would eat a little bit, then drop it.
Davidson realized these mice didn’t know they were full. He says something similar may happen in human brains when people eat a diet high in fat and sugar. If our brain system is damaged by that diet, that makes it harder for us to stop eating that diet.
The evidence is growing. In another study by Cambridge psychologist Lucy Cheke, her researchers asked obese（肥胖的）and thin people to do a memory task, a virtual treasure hunt. The subjects had to hide something in a scene across various computer sessions（会话框）, then they were asked what they hid, where they hid it and in which session. The obese people were 15-20 percent worse than the thin ones in all aspects of the experiment.
Cheke says with the link between obesity and the brain growing as a field of research, we could see more ways of targeting obesity. For example, if the problem is that obese peopled diet degrades their memory, perhaps making peopled meals more memorable would help them eat less bad stuff. Previous researches showed that watching TV while eating will probably make people eat more, get hungry in the afternoon and eat more at dinner. So Cheke suggests not watching TV while eating. It is one of the easy changes people can make that don’t involve much self-control, but that makes a great difference.

【推荐3】Stars blazed(猛烈地燃烧)in the sky above Spook like a million tiny suns. They shone through the mists, which had during the last year become thinner and weaker. At first, he had thought the world itself was changing. Then he had realized that it was just his feeling. Somehow, by burning tin in his body for so long, he had permanently strengthened his senses to a point far beyond what other Allomancers could attain.
The burned tin had begun as a reaction to Clubs’s death. Spook still felt terrible about the way he’d escaped, leaving his uncle to die. During those first few weeks, Spook had burned his metals as almost a self-punishment he’d wanted to feel everything around him, take it all in, even though it was painful, or perhaps because it was painful.
But then he’d started to change, and that had worried him. But, the crew always talked about how hard Vin pushed herself. She rarely slept, using pewter(白镴)to keep herself awake and alert. Spook didn’t know how that worked he was no Mistborn, and could only bum one metal but he figured that if burning his one metal could give him an advantage, he’d better take it, because they were going to need every advantage they could get.
The starlight was like daylight to him. During the actual day, he had to wear a cloth tied across his eyes to protect them, and even then going outside was sometimes blinding. His skin had become so sensitive that each little stone in the ground felt like a knife jabbing(猛刺)him through the bottom of his feet. The cold spring air seemed freezing, and he wore a thick cloak(斗篷).
However, he had concluded that these discomforts were small prices to pay for the opportunity to become whatever it was he had become. As he moved down the street, he could hear people turning over and over in their beds, even through their walls. He could sense a footstep from yards away. He could see on a dark night as no other human ever had.
________________. Always before, he’d been the least important member of the crew the dismissible boy who served as a handy man or kept watch while the others made plans. He didn’t feel annoyed with them for that he’d been right to give him such simple duties. ________________. Because of his street dialect, he’d been difficult to understand, and while all the other members of the crew had been carefully picked, Spook had joined through the back door since he was Clubs’s nephew.
Spook sighed, sticking his hands in his trouser pockets as he walked down the too-bright street. He could feel each and every thread of the cloth.
Dangerous things were happening he knew that: the way the mists lasted longer during the day, the way the ground shook as if it were a sleeping man, periodically(周期性地)suffering a terrible dream. Spook worried he wouldn’t be of much help in the critical days to come. A little over a year before, his uncle had died after Spook fled the city. Spook had run out of fear, but also out of a knowledge of his lack of power. ________________. He wouldn’t have been able to help during the campaign.
He didn’t want to be in that position again. He wanted to be able to help, somehow. He wouldn’t run into the woods, hiding while the world ended around him. He was sent to gather as much information as he could about the Citizen and his government there, and so Spook intended to do his best. If that meant pushing his body beyond what was safe, so be it.
He approached a large crossing. He looked both ways down the intersecting(交叉的)streets the view clear as day to his eyes. I may not be Mistborn, and I may not be emperor, he thought. But I’m something. Something new. Something people would be proud of Maybe this time I can help. ________________.

【推荐1】Engineers have launched a huge garbage collection device to gather plastic material floating in the Pacific Ocean between California and Hawaii.
The plastic makes up what is called the Great Pacific Garbage Patch. It is the world’s largest spread of garbage, at twice the size of the state of Texas.
The organization Ocean Cleanup created the collection device, whose founder is Boyan Slat, a 24-year-old inventor from the Netherlands.
Slat was just 16 years old when he was moved to clean up the oceans. Last Saturday, a ship pulling the pipe-shaped floating barrier left San Francisco for the Garbage Patch. The barrier, called the floater, is 600 meters across. Attached to it is a screening skirt that hangs three meters down in the water.
The screen is designed to collect the plastic as it moves through the water. Sea animals can safely swim under the barrier.
The cleanup system also comes with lights powered by the sun, cameras, and other special devices. So the system can communicate its position at all times. That way a support ship can find it every few months to remove the plastic it has collected.
“The free-floating barriers are made to survive extreme weather conditions and damage from continue use. They will stay in the water for twenty years and in that time collect 90 percent of the garbage in the patch,” Slat added.
George Leonard is the chief scientist. He expressed concern about the cleaning project. He said even if plastic garbage can be taken out of the oceans, more continues to enter the water each year. He also raised concern that animals might be captured by the net hung below the surface.
But, Boyan Slat said he did not think that would happen. The system will act as a “big boat that stands still in the water”, with nothing for sea creatures to get caught in.

【推荐2】A new type of rechargeable battery can rapidly produce charges in large quantities even at-70° Celsius, a temperature where the typical lithium-ion(锂离子) batteries that power many of today's devices don't work. Batteries that bear such extremely cold conditions could help build electronics that function in some of the coldest places on Earth or on other planets.
Inside lithium-ion batteries, ions flow between positive and negative electrodes(电极), where the ions are fixed and then set free to travel back through a substance called an electrolyte(电解质) to the other end. As the temperature drops, the ions move slowly through the electrolyte. The cold also makes it hard for ions to get rid of the electrolyte material that sticks onto them. As they cross the battery, ions must cast the matter to fit into the electrode material, explains a battery researcher at Fudan University. At-40℃, conventional lithium-ion batteries deliver about 12 percent of the charge they do at room temperature; at-70℃, they don't work at all.
The new battery contains a special kind of electrolyte that allows ions to flow easily between electrodes even in the bitter cold. The researchers also fitted their battery with electrodes made of organic compounds(有机化合物) rather than the typical transition-metal-rich materials. lons can flow freely in this organic material without having to get rid of the electrolyte material attached to them. So these organic electrodes catch and release ions more easily than electrodes in normal batteries, even at low temperatures, Dong says.
Because the ions flow better and connect more readily with the electrodes at low temperatures, the new battery keeps about 70 percent of its room-temperature charging capacity even at-70℃. Still, battery cells in the new design pack less energy per gram than standard lithium-ion batteries, says Shirley Meng, a material scientist in California. She would like to see whether a more energy-dense(能量密度高的) version of the battery can be built.

【推荐3】Does happiness have a scent?
When someone is happy, can you smell it?
You can usually tell when someone is happy based on seeing them smile, heating them laugh or perhaps from receiving a big hug. But can you also smell their happiness? Surprising new research suggests that happiness does indeed have a scent, and that the experience of happiness can be transmitted through smell, reports Phys.org.
For the study, 12 young men were shown videos meant to bring about a variety of emotions while researchers gathered sweat samples from them. All of the men were healthy and none of them were drug users or smokers, and all were asked to abstain from drinking or eating smelly foods during the study period.
Those sweat samples were then given to 36 equally healthy young women to smell, while researchers monitored their reactions. Only women were selected to smell the samples, apparently because previous research has shown that women have a better sense of smell than men and are also more sensitive to emotional signaling—though it's unclear why only men were chosen to produce the scents.
Researchers found that the behavior of the women after smelling the scents--particularly their facial expressions--indicated a relationship between the emotional states of the men who produced the sweat and the women who sniffed them.
"Human sweat produced when a person is happy brings about a state similar to happiness in somebody who breathes this smell," said study co-author Gun Semin, a professor at Koc University in Turkey.
This is a fascinating finding because it not only means that happiness does have a scent, but that the scent is capable of transmitting the emotion to others. The study also found that other emotions, such as fear, seem to carry a scent too. This ensures previous research suggesting that some negative emotions have a smell, but it is the first time this has proved to be true of positive feelings.
Researchers have yet to isolate(分离) exactly what the chemical compound for the happiness smell is, but you might imagine what the potential applications for such a finding could be. Happiness perfumes, for instance, could be invented. Scent therapies (香味疗法) could also be developed to help people through depression or anxiety.
Perhaps the most surprising result of the study, however, is our broadened understanding of how emotions get communicated, and also how our own emotions are potentially managed through our social context and the emotional states of those around us.

【推荐1】Although air travel comes with jet lag, delays and awful food, it offers a brief digital detox—a precious few hours away from the wave of emails, messages and app announcements. But not anymore, In flight Wi-Fi is getting faster and cheaper, and is an increasingly common offering on budget and flagship airlines.
But how does in-flight Wi-Fi actually work? To simplify, there are two ways for an internet signal to reach your device when you’re up in the clouds. The first is via ground based mobile broadband towers, which send signals up to the aircraft’s antennas (天线). As you travel into different sections of airspace, the plane automatically connects to signals from the nearest tower, so there is (in theory at least) no interruption to your Internet. But if you’re passing over large areas of water or particularly remote zones, connectivity can be an issue.
The second method uses satellite technology. Planes connect to satellites in space (35,000 km above the planet), which send and receive signals via receivers and transmitters. Information is transmitted to and from your smart phone via an antenna on the top of the aircraft. These are the same satellites that are used in television signals and weather forecasting. Information is passed between the ground and the plane via the satellite.
All of that technology is expensive. The costs are usually passed on to customers. Over half of the world’s aircraft will be equipped with in-flight Wi-Fi within the next few years. It is set to become a billion-dollar industry by 2020. In the near future you’ll need to find a better excuse than “Sorry I missed your message—I was on a plane”.

【推荐2】When is cleaning walls a crime? When you're doing it to create art, obviously. A number of street artists around the world have started expressing themselves through a practice known as reverse graffiti (反向涂鸦). They find dirty surfaces and paint them with images or messages using cleaning brushes or pressure hoses (高压水管). Either way, it's the same principle: the image is made by cleaning away the dirt. Each artist has their own individual style but all artists share a common aim: to draw attention to the pollution in our cities. The UK’s Paul Curtis, better known as Moose, operates around Leeds and London and has been commissioned by a number of companies to make reverse graffiti advertisements.
Brazilian artist, Alexandre Orion, turned one of Sao Paulo's transport tunnels into an amazing wall painting in 2006 by getting rid of the dirt. Made up of a series of white skulls (颅骨), the painting reminds drivers of the effect their pollution is having on the planet. “Every motorist sits in the comfort of their car, but they don't give any consideration to the price their comfort has for the environment and consequently for themselves,” says Orion.
The anti-pollution message of the reverse graffiti artists confuses city authorities since the main argument against graffiti is that it spoils the appearance of both types of property: public and private. This was what Leeds City Council said about Moose's work: “Leeds residents want to live in clean and attractive neighborhoods. We view this kind of advertising as environmental damage and will take strong action against it.” Moose was ordered to “clean up his act.” How was he supposed to do this: by making all property he had cleaned dirty again?
As for the Brazilian artist's work, the authorities were annoyed but could find nothing to charge him with. They had no other option but to clean the tunnel-but only the parts Alexandre had already cleaned. The artist merely continued his campaign on the other side. The city officials then decided to take drastic action. They not only cleaned the whole tunnel but every tunnel in Sao Paulo.

Transportation in Venice
The Grand Canal，which cuts through the center of the city, is like Venice’s main street in this canal-filled city. The boats runs along the Grand Canal from the train station and makes many stops, so it’s a good way to visit the main canal and get a good overview of the city. If you want something more up close and personal, take a taxi and a gondola, though they tend to be more expensive.
Venice Festivals
Venice’s Carnevale held 40 days before Easter, is one of the most lively and colorful celebrations in Italy. The Venetians go all out, wearing festive masks and costumes for a 10-day street party. In July, there’s the Redentore Regatta, an important festival held right on the Grand Canal.
Guided Tours
You’ll find guided tours for every place worth visiting, from well-known palaces to lesser-known destinations. Also, there are food tours and classes in rowing, cooking or making those beautiful theatrical masks Venice is famous for.
When to Go
Since it’s near the sea. Venice has gentle weather, although it can be rainy there nearly all year round. Venice experiences high-water flooding about 60 days a year, from October through early January. In Venice, make sure you have some way to check the changeable weather every day.
