3 . Who is a genius? This question has greatly interested humankind for centuries.
Let’s state clearly: Einstein was a genius. His face is almost the international symbol for genius. But we want to go beyond one man and explore the nature of genius itself. Why is it that some people are so much more intelligent or creative than the rest of us? And who are they?
In the sciences and arts, those praised as geniuses were most often white men, of European origin. Perhaps this is not a surprise. It’s said that history is written by the victors, and those victors set the standards for admission to the genius club. When contributions were made by geniuses outside the club—women, or people of a different color or belief—they were unacknowledged and rejected by others.
A study recently published by Science found that as young as age six, girls are less likely than boys to say that members of their gender(性别)are “really, really smart.” Even worse, the study found that girls act on that belief: Around age six they start to avoid activities said to be for children who are “really, really smart.” Can our planet afford to have any great thinkers become discouraged and give up? It doesn’t take a genius to know the answer: absolutely not.
Here’s the good news. In a wired world with constant global communication, we’re all positioned to see flashes of genius wherever they appear. And the more we look, the more we will see that social factors(因素)like gender, race, and class do not determine the appearance of genius. As a writer says, future geniuses come from those with “intelligence, creativity, perseverance(毅力), and simple good fortune, who are able to change the world.”

4 . During an interview for one of my books, my interviewer said something I still think about often. Annoyed by the level of distraction (干扰) in his open office, he said, “That’s why I have a membership at the coworking space across the street — so I can focus”. His comment struck me as strange. After all, coworking spaces also typically use an open office layout (布局). But I recently came across a study that shows why his approach works.
The researchers examined various levels of noise on participants as they completed tests of creative thinking. They were randomly divided into four groups and exposed to various noise levels in the background, from total silence to 50 decibels (分贝), 70 decibels, and 85 decibels. The differences between most of the groups were statistically insignificant; however, the participants in the 70 decibels group — those exposed to a level of noise similar to background chatter in a coffee shop — significantly outperformed the other groups. Since the effects were small, this may suggest that our creative thinking does not differ that much in response to total silence and 85 decibels of background noise.
But since the results at 70 decibels were significant, the study also suggests that the right level of background noise — not too loud and not total silence — may actually improve one’s creative thinking ability. The right level of background noise may interrupt our normal patterns of thinking just enough to allow our imaginations to wander, without making it impossible to focus. This kind of “distracted focus” appears to be the best state for working on creative tasks.
So why do so many of us hate our open offices? The problem may be that, in our offices, we can’t stop ourselves from getting drawn into others’ conversations while we’re trying to focus. Indeed, the researchers found that face-to-face interactions and conversations affect the creative process, and yet a coworking space or a coffee shop provides a certain level of noise while also providing freedom from interruptions.

5 . What is life? Like most great questions, this one is easy to ask but difficult to answer. The reason is simple: we know of just one type of life and it’s challenging to do science with a sample size of one. The field of artificial life-called ALife for short — is the systematic attempt to spell out life’s fundamental principles. Many of these practitioners, so-called ALifers, think that somehow making life is the surest way to really understand what life is.
So far no one has convincingly made artificial life. This track record makes ALife a ripe target for criticism, such as declarations of the field’s doubtful scientific value. Alan Smith, a complexity scientist, is tired of such complaints. Asking about “the point” of ALife might be, well, missing the point entirely, he says. “The existence of a living system is not about the use of anything.” Alan says. “Some people ask me, ‘So what’s the worth of artificial life?’ Do you ever think, ‘What is the worth of your grandmother?’”
As much as many ALifers hate emphasizing their research’s applications, the attempts to create artificial life could have practical payoffs. Artificial intelligence may be considered ALife’s cousin in that researchers in both fields are enamored by a concept called open-ended evolution (演化). This is the capacity for a system to create essentially endless complexity, to be a sort of “novelty generator”. The only system known to exhibit this is Earth’s biosphere. If the field of ALife manages to reproduce life’s endless “creativity” in some virtual model, those same principles could give rise to truly inventive machines.
Compared with the developments of Al, advances in ALife are harder to recognize. One reason is that ALife is a field in which the central concept — life itself — is undefined. The lack of agreement among ALifers doesn’t help either. The result is a diverse line of projects that each advance along their unique paths. For better or worse, ALife mirrors the very subject it studies. Its muddled (混乱的) progression is a striking parallel (平行线) to the evolutionary struggles that have shaped Earth biosphere.
Undefined and uncontrolled, ALife drives its followers to repurpose old ideas and generated novelty. It may be, of course, that these characteristics aren’t in any way surprising or singular. They may apply universally to all acts of evolution. Ultimately ALife may be nothing special. But even this dismissal suggests something:perhaps, just like life itself throughout the universe, the rise of ALife will prove unavoidable.

Mike Shepherd(2011) Skiddaw in Winter Cumbria, England | It was an extremely cold winter’s evening and freezing fog hung in the air. I climbed to the top of a small rise and realised that the mist was little more than a few feet deep, and though it was only a short climb, I found myself completely above it and looking at a wonderfully clear view of Skiddaw with the sun setting in the west. I used classical techniques, translated from my college days spent in the darkroom into Photoshop, to achieve the black—and—white image(图像). |
Timothy Smith(2014) Macclesfield Forest Cheshire, England | I was back in my home town of Macclesfield to take some winter images. Walking up a path through the forest towards Shutlingsloe. a local high point, I came across a small clearing and immediately noticed the dead yellow grasses set against the fresh snow. The small pine added to the interest and I placed it centrally to take the view from the foreground right through into the forest. |

8 . Race walking shares many fitness benefits with running, research shows, while most likely contributing to fewer injuries. It does, however, have its own problem.
Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-kilometer race walk, which is about five miles longer than the marathon. But the sport’s rules require that a race walker’s knees stay straight through most of the leg swing and one foot remain in contact (接触) with the ground at all times. It’s this strange form that makes race walking such an attractive activity, however, says Jaclyn Norberg, an assistant professor of exercise science at Salem State University in Salem, Mass.
Like running, race walking is physically demanding, she says, According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calories(卡路里) per hour, which is approximately twice as many as they would burn walking, although fewer than running, which would probably burn about 1,000 or more calories per hour.
However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research, runners hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step.
As a result, she says, some of the injuries associated with running, such as runner’s knee, are uncommon among race walkers. But the sport’s strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to be cautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice.

9 . Sitting in the garden for my friend’s birthday. I felt a buzz (振动) in my pocket. My heart raced when I saw the email sender’s name. The email started off: “Dear Mr Green, thank you for your interest” and “the review process took longer than expected.” It ended with “We are sorry to inform you…” and my vision blurred (模糊). The position—measuring soil quality in the Sahara Desert as part of an undergraduate research programme — had felt like the answer I had spent years looking for.
I had put so much time and emotional energy into applying, and I thought the rejection meant the end of the road for my science career.
So I was shocked when, not long after the email, Professor Mary Devon, who was running the programme, invited me to observe the work being done in her lab. I jumped at the chance, and a few weeks later I was equally shocked—and overjoyed—when she invited me to talk with her about potential projects I could pursue in her lab. What she proposed didn’t seem as exciting as the original project I had applied to, but I was going to give it my all.
I found myself working with a robotics professor on techniques for collecting data from the desert remotely. That project, which I could complete from my sofa instead of in the burning heat of the desert, not only survived the lockdown but worked where traditional methods didn’t. In the end, I had a new scientific interest to pursue.
When I applied to graduate school, I found three programmes promising to allow me to follow my desired research direction. And I applied with the same anxious excitement as before. When I was rejected from one that had seemed like a perfect fit, it was undoubtedly difficult. But this time I had the perspective (视角) to keep it from sending me into panic. It helped that in the end I was accepted into one of the other programmes I was also excited about.
Rather than setting plans in stone, I’ve learned that sometimes I need to take the opportunities that are offered, even if they don’t sound perfect at the time, and make the most of them.
