1 . Imagine a horizontal line. The very left is marked one thousand and the very right is marked one billion. On this line, where would you add a marker to represent one million? If you said somewhere in the middle, you answered the same as the roughly 50 percent of people who have done this exercise in a number line study. But the answer is actually much closer to one thousand since there are one thousand millions in one billion.
This error makes sense because “our human brains are pretty bad at comprehending large numbers,” says Elizabeth Toomarian, an educational neuroscientist at Stanford University. Our brain is built to understand how much of something is in its environment. But comprehending the national debt or imagining the size of our universe? “We certainly can use our brains in that way, but we’re recycling these sorts of evolutionarily (进化地) old brain architectures to do something really new,” she says. In other words, it’s not our fault that we have trouble wrapping our heads around big numbers.
So what can we do about the struggle to understand big numbers? It is suggested to use metaphors, analogies (类比) and visualizations. These techniques bring big numbers down to a more comprehensible scale (比例) and ideally make it relevant to something in our daily lives. For example, it may be difficult for most people to accurately place the extinction of the dinosaurs on a timeline between the Big Bang and humans because the first two both seem to be placed to the distant path. But when conceptualizing (概念化) these events using a “calendar”, it becomes easier. The Big Bang occurred at 12 a.m. on January 1st on the calendar. Dinosaurs were only present for roughly the last week of the year. And humans only emerged in the last eight sends December 31st, at 12:59:52 p.m. It’s clear now that dinosaurs are much closer to humans than the Big Bang on a timeline.
These metaphors and analogies are important if people are to really weigh the costs and benefits of events in their lives. The concept not only applies to long-term decisions, but public policies.

3 . A scientist goes to a forest to study monkeys. He or she wants to study their habits and behavior. But the problem is: how to know who’s who?
In the past, scientists had to make marks on each of the animals to distinguish them. But in the future, they may have a much easier way to tell them apart thanks to facial recognition technology.
A research team from China’s Northwest University is using facial recognition technology to identify thousands of snub-nosed monkeys (金丝猴) that live on Qinling Mountain in Shaanxi province.
Similar to human facial recognition, the technology that is used to identify monkeys uses their facial features to create a database that includes every monkey, Xinhua reported.
“When the system is fully developed, we can connect it with cameras set up in the mountains. The system will automatically recognize the monkeys, name them and analyze their behavior,” said Zhang He, a member of the research team.
“For each snub-nosed monkey, we have 700 to 800 image samples, and the recognition success rate is 94 percent,” Zhang added.
Compared with facial recognition technology for humans, facial recognition technology for monkeys is more complicated because monkeys have hairier faces. The color of their hair causes them to blend into their environment. These factors make it harder for computers to do the job.
“Monkeys do not cooperate with researchers in the same way humans do. It is difficult to take high-quality pictures and videos of them, which are needed to improve the system,” said Li Baoguo, leader of the research team.
Currently, there are about 4,000 snub-nosed monkeys living on Qinling Mountain. The team’s goal is to successfully identify every monkey that lives there.

4 . Edward rose early on the New-year morning. He looked in every room and wished a Happy New Year to his family. Then he ran into the street to repeat that to those he might meet.
When he came back, his father gave him two bright, new silver dollars.
His face lighted up as he took them. He had wished for a long time to buy some pretty books that he had seen at the bookstore.
He left the house with a light heart, expecting to buy the books. As he ran down the street, he saw a poor family.
“I wish you a Happy New Year.” said Edward, as he was passing on. The man shook his head.
“You are not from this country.” said Edward. The man again shook his head, for he could not understand or speak his language. But he pointed to his mouth and to the children shaking with cold, as if (好像) to say, “These little ones have had nothing to eat for a long time.”
Edward quickly understood that these poor people were in trouble. He took out his dollars and gave one to the man, and the other to his wife.
They were excited and said something in their language, which doubtless meant, “We thank you so much that we will remember you all the time.”
When Edward came home, his father asked what books he had bought. He hung his head a moment, but quickly looked up.
“I have bought no books”, said he. “I gave my money to some poor people, who seemed to be very hungry then.” He went on, “I think I can wait for my books till next New Year.”
“My dear boy,” said his father, “here are some books for you, more as a prize for your goodness of heart than as a New-year gift.”
“I saw you give the money cheerfully to the poor German family. It was nice for a little boy to do so. Be always ready to help others and every year of your life will be to you a Happy New Year.”

6 . Researchers at the Indian Institute of Technology (IIT) Madras have been working on a fascinating new way to identify people: using the ways of their breath. This idea could change how we unlock our phones and access secure places.
The key to this technology lies in the way we breathe out. Every person has a unique way of breathing air, which creates specific turbulence (涡流) patterns. The IIT Madras team, led by Prof. Mahesh Panchagnula, has developed a method of catching these unique patterns and using them as a biometric (生物特征识别的) signature, similar to how fingerprints are used today.
They conducted tests with breath samples from 94 people and found that their system could correctly confirm the person’s identity with an impressive accuracy of 97%. However, when it came to identifying someone without knowing who they were beforehand, the accuracy was around 50%. This means the technology is great at confirming if someone is who they claim to be, but it still needs improvement in recognizing people without any prior information. What makes this research exciting is its potential beyond just unlocking phones. It could play a significant role in personalized medicine. Since the way we breathe can give insights into our health, this technology could help doctors tailor treatments to individual patients more effectively.
In a similar study at Kyushu University in Japan, researchers developed an artificial system that identifies people based on how their breath smells. This system showed a high accuracy rate of 97.8% in identifying individuals. However, this method currently requires people to fast (禁食) for six hours before testing, indicating that it still needs to be improved to be more practical for everyday use.
These advancements in using human breath for identification are not just about adding another cool feature to our smartphones. They represent a significant step forward in biometric technology, which could have far-reaching implications in security, medicine, and personal technology. This research at IIT Madras and Kyushu University is pioneering a new way of using the unique patterns of our breath for identification purposes, potentially revolutionizing (变革) how we interact with technology and receive medical care.

9 . “A moth (飞蛾) to a flame” is often used to indicate an inescapable attraction, yet it is a strange example of animal behavior that continues to confuse people today. Scientists have raised a number of theories over the years to explain why. One holds that insects flying at night are following their nature to fly toward the brightest spot in their field of vision, which they mistake for the sky. Another suggests that insects are trying to warm themselves with the heat produced by the light. The most popular theory, though, is that insects are confusing lights with the moon or other celestial bodies (天体) that they normally use to navigate (导航).
To find out the real reason, the team carried out a first set of experiments in an insect flight area. The researchers used eight high-speed infrared (红外线) cameras equipped with motion-capture technologies to track 30 insects from three moth and two dragonfly species. They also flew lab-raised insects from six different insect orders that were too small for motion-capture technology, including fruit flies and honeybees, to make sure different insects all showed similar responses to light. Working with co-author Pablo Allen of the Council on International Educational Exchange in Monteverde, Costa Rica, the researchers put heavy cameras, lights and tripods in two field sites to gather behavioral data from insects in the wild.
The team was able to confirm that insects were not beelining to the light but rather circling it as they tilted (倾斜) in an attempt to turn their backs toward it. This behavior, known as a “dorsal light response”, normally helps insects to remain in an unchanging path of flight that is properly lined to the horizon (地平线). Artificial light that arrives from a point source causes them to fly in unpredictable patterns as they try to turn their backs to what they are mistaking for the sky.
Now research might have finally solved the mystery mentioned first: artificial light confuses insects’ ability to turn themselves to the horizon, confusing their sense of what is up and down and causing them to fly in circles.
