1 . In 1999, David Dunning and Justin Kruger did a series of studies evaluating people’s competence in certain areas, including grammar, humor and logic. The people in the studies were asked to evaluate their own abilities in each area. Dunning and Kruger found that people who scored low on the tests have the tendency to overestimate their abilities, indicating that people who lack skills tend to lack the ability to realize their shortcomings.
This principle has become known as the Dunning-Kruger effect. It occurs because only when people have skills in a given area are they equipped to evaluate their own skills. Admittedly, most people are overconfident in their abilities. They want to believe that they are more capable, knowledgeable and even superior to others, and when someone really wants something to be true, it can be hard for them to admit that it isn’t. By the way, the opposite of the Dunning-Kruger effect also happens: capable people have a more accurate view of their own abilities, and sometimes they even underestimate themselves.
It’s tempting (吸引人的) to think of the Dunning-Kruger effect as a problem. People may even laugh at those who think themselves more competent than they truly are, but everyone has areas where they lack competence, and the Dunning-Kruger effect means they may be relatively bad at self-evaluation in those areas. Even if someone is very intelligent in general, there are still things they don’t know much about. Expertise in one area cannot always be transferred to other areas.
That’s why it’s important to keep digging for information even when you think you’ve found answers. It can also be helpful to check your ideas with other people. Receiving negative feedback can hurt, but if you’re willing to listen, it can help you grow. Even just keeping in mind that the Dunning-Kruger effect exists can help you stay modest, accept criticism and, thus, keep learning throughout your life.

4 . Falcons are powerful birds that may be trained to hunt in cooperation with humans. The art of training falcons as “hunting dogs of the skies” is called falconry (训鹰术). It was developed in the ancient Arabian Desert around 4000 B. C. In the past, falconry mainly involved hunting with falcons to supplement one’s diet. But now, it has become the favorite sport and pastime in the Arabian Peninsula.
Falconry includes three major processes: acquiring the falcons, training them, and hunting with them. Every year, falconers begin capturing wild falcons in June and July, the migration season. The best birds to catch are the ones with naturally nurtured hunting skills, aged one or two years. Once the falcons are captured, their heads are immediately covered with a leather hood. This is essential because they imprint as their master whomever they see first after the hood is removed. Right after a bird is caught, the training process starts. It begins by depriving (剥夺) the bird of food to make it easier to tame. The birds are taught to know their own name and respond to their master when called. Arab falconers live with their birds day and night in order to build a strong relationship with them.
By the end of October or mid-November, the trained falcons are ready to hunt in the desert. They have excellent vision, 2. 6 times greater than that of a human. They are also the fastest divers on the planet. One hunting technique that sets them apart from other animals is that they can be trained to deliver their prey, without killing it first. This is vital in Islamic culture because animals used for food must still be alive to ensure that the meat is halal, that is, properly prepared according to Islamic law.
Falcons have played such a crucial role in traditional Islamic cultures that a number of countries in the Middle East have made them their national bird. Falconry has grown so popular that specialist hospitals have been established to take care of these magnificent birds. Falcons are even issued their own passports. They are the only animals in the United Arab Emirates that are legally allowed to travel inside planes, enjoying a level of luxury that some humans can only dream of.

6 . I was the only kid in college with a reason to go to the mailbox, because my mother never believed in email or cell phones. I was literally waiting to get a letter to see how her weekend had gone, which was usually the warmest comfort for a girl of my age.
So when I moved to New York and got sucker-punched in the face by depression, I did the only thing I could think of. I wrote those same kinds of letters like my mother for strangers, and slipped them all over the city. I blogged about those letters and crazily promised if asked for a hand-written letter, I would write one.
Overnight, my inbox became this harbor of heartbreak — a single mother in Sacramento, a girl being bullied in Kansas, a 22-year-old immigrant, all asking me to write them and gave them a reason to wait by the mailbox. And this is how I initiated a global organization, fueled by those trips to the mailbox.
It is awesome. In fact, the thing about these letters is that most of them have been written by people who have grownup into a paperless world where some best conversations happen on a screen. We have learned to record our pain on to Facebook, and we speak swiftly in 140 characters or less.
But it’s not about efficiency. And I could tell you about a woman whose husband was traumatized (受精神创伤) by his war experiences in Afghanistan and isolated himself, and her love letters slipped throughout the house eventually got him back to her. Or a man, who decides to take his own life, finally sleeps soundly with a stack of letters from strangers slipped beneath his pillow.
The scare the kinds of stories that convince me that letter-writing will always be needed even in these days, because it is an art now.

8 . German physicist Albert Einstein is one of the most famous scientists of all time, the personification of genius and the subject of a whole industry of scholarship. In The Einsteinian Revolution, two experts on Einstein’s life and his theory of relativity―Israeli physicst Hanoch Gutfreund and German historian of science Jurgen Renn—offer an original and penetrating(厚利的) analysis of Einstein’s revolutionary contributions to physics and our view of the physical world.
By setting Einstein’s work in the long course of the evolution of scientific knowledge, Gutfreund and Renn discover the popular misconception of Einstein as an unconventional scientific genius who single-handedly created modern physics—and by pure thought alone.
As a large part of the book explains, Einstein typically argued that science progresses through steady evolution, not through revolutionary breaks with the past. He saw his theory of relativity not as something from scratch, but a natural extension of the classical physics developed by pioneers such as Italian astronomer Galileo Galilei and English physicist Isaac Newton in the sixteenth and seventeenth centuries, as well as nineteenth-century physicists.
The authors highlight how classical physics cannot be separated cleanly from modem Einsteinian physics. The book also includes substantial sections on Polish astronomer Nicolaus Copernicus and Galileo whose methods inspired Einstein. When Einstein considered himself as standing on their shoulders, he meant that, without their contributions, he would not have formulated(阐述) the theory of relativity.
The Einsteinian Revolution is an important and thought-provoking contribution to the scholarly literature on Einstein and his surprising scientific creativity between 1905 and 1925. Gutfreund and Renn might not have given the final answer as to why Einstein, of all people, revolutionized physics in the way that he did. But they argue in fascinating detail that, to understand his genius, one must take into account not just the earlier history of physics but also the history of knowledge more broadly. Although not always an easy read, the book will interest physicists and historians alike.

10 . Nanako Hama gets a lot of mail, mostly from strangers who live in her home city of Tokyo. In light envelopes, they send locks of their hair, hoping to recycle it.
People generate a huge amount of hair waste. Nearly all of that waste ends up in landfill, where it can release harmful greenhouse gases that contribute to climate change.
But hair possesses useful qualities that it’s a shame to simply throw it away. That’s why people all around the world, like Hama, have been collecting hair and finding innovative ways to recycle it, including making mats (垫子)out of it for removing oil leaks.
Hama is part of the nonprofit Matter of Trust (MoT) members working at more than 60 centers dotted across 17 countries, using machines to make hair donated from local salons and individuals into square mats, which are then used to clean up the floating oil.
Hair is particularly well-suited for this, says MoT co-founder Lisa Gautier. “That’s because its rough sort of outer layer lets oil stick to it.” MoT’s mats have been used in major oil leaks. including the 2010 Deepwater Horizon and 2007 Cosco Busan incidents.
In a 2018 study, Murray, an environmental scientist at the University of Technology Sydney, in Australia found that mats made of recycled human hair could absorb 0.84 grams of oil onto its surface for every gram of hair—significantly more than polypropylene (聚丙烯), a type of plastic that’s typically used to clean up floating oil.
Besides, hair is also useful as fertilizer (化肥). Hair contains a relatively high nitrogen (氮), a chemical element crucial for plant growth, and each lock of hair is made of roughly 16 percent of this essential nutrient. Last year, more than 560 gallons of liquid fertilizer made from human hair was sold to farmers in northern Tanzania and the feedback from the farmers has been very encouraging.
“It’s just a great way to use hair in a productive way. Hair is an answer literally hanging in front of our eyes—for oil and soil,” Hama says.
