The oddness of life in space never quite goes away. Here are some examples.

    While watching the Olympics the other night, I came across an unbelievable sight. It was not a gold medal, or a world record broken, but a show of courage.

    The event was swimming and started with only three men on the blocks. For one reason or another, two of them false started, so they were disqualified. That left only one to complete. It would have been difficult enough, not having anyone to race against, even though the time on the clock is important.

    I watched the man dive off the block and knew right away that something was wrong. I'm not an expert swimmer, but I can tell a good dive from a poor one, and this was not exactly medal quality. When he resurfaced, it was evident that the man was not out for gold—his arms were waving in an attempt at freestyle. The crowd started to laugh. Clearly this man was not a medal competitor.

    I listened to the crowd begin to laugh at this poor man who was clearly having a hard time. Finally he made his turn to start back. It was pitiful. He made a few desperate strokes and you could tell he was worn out.

    But in those few awful strokes, the crowd had changed.

    No longer were they laughing, but beginning to cheer. Some even began to stand and shout “Come on, you can do it!” and he did.

    A clear minute past the average swimmer, this young man finally finished his race. The crowd went wild. You would have thought that he had won the gold, and should have. Even though he recorded one of the slowest times in Olympic history, this man gave more heart than any of the other competitors.

    Just a short year ago, he had never even swum, let alone race. His country had been invited to Sydney.

    In a competition where athletes remove their silver medals feeling they have somehow been cheated out of gold, or when they act so proudly in front of their competitors, it is nice to watch an underdog.

At school, I was in the top set for maths. My teachers recommended that I study economics and statistics as my A-level subjects, but I had my mind set on a life fulfilled by the arts.

In fact, I was a victim of a gender stereotype made stronger since birth, that men do science and maths and women do arts or languages. Computer science, technology and physics just did not figure in my teenage world view. Nobody popular in my school chose to study those subjects.

Reality struck hard when I began attending job interviews and interviewers would say: "It's great that you speak foreign languages, but what else do you do?" Nobody asked my friends who had studied science or technology those questions.

A survey recently showed that three of the best-paid jobs for women are in the technology sector. It's a sector that really can change the world. We must show girls that technology has an effect on every industry out there, from fashion to architecture to journalism. Anybody can learn to code and these days it's as important as reading and writing. I've realized that at university I'd achieved the wrong kind of literacy. Not being able to code limit your impact on the world far more than an ignorance of great literature.

Now I have a five-year-old daughter. I don't want her to blindly follow gender roles the way I did. I want her to know the fact that a science or technical degree will not limit her creativity but expand it and broaden her horizons far more than my arts background could. I'm exposing her to Minecraft and apps, which help improve analytical thinking and problem solving skills. I'm hoping that my daughter will discover and accept her potentials in science and want to change the world.

During a pandemic (流行病), for many reasons, there are lots of poor parents who are isolated (隔离) with their kids, or roommates who are stuck together in an apartment. But what about the people who have nobody to talk to?

It is common that people feel lonely. However, during the pandemic, this situation can be much worse for experiences like long-time hospital stays or being unable to move due to poor health, disability or age.

Recently, a friendly robot named Robin got a test run in the children's treatment center of the Wigmore Clinic in Yerevan. About as tall as an 8-year-old child, Robin's plastic body and square head may not put you in mind of a human partner, but its face screen containing two big eyes and expressive brows (眉毛) is attractive, which can help children forget their stress for a while.

A hospital can be very stressful for anybody. And the time of treatment and recovery might seem tiresomely long to an adult stuck in a hospital bed. For a child who can't play with his or her friends or sometimes even family, the long course and boring atmosphere seem unbearable. That's where Robin comes in. It can recognize (识别) facial expressions and use the mood of a talk to build personalized, natural conversations and dialogues with a lonely child in the way another child might use. Robin also plays games, tells stories, and makes children take part in various other activities.

According to Expper Technologies, the makers of Robin, during the program with Wigmore Clinic, Robin improved the experience of children in the hospital by 26 percent over those who did not have the chance to play with Robin, and reduced their stress levels by 34 percent during their hospital stay. Mary, whose son was one of those users, said, "Thanks to Robin, my son became happy every day during this pandemic." John Smith, a father of a five-year-old girl in the clinic, told a reporter, "Robin is a great partner. It brings big smiles to my daughter's face."

The Netherlands is the only country in the world with more bicycles than residents. By 2022, the Netherlands has had a total of about 23 million bicycles, with an ownership rate of 1.35 bikes per person. One study published by the National Institutes of Health (NIH) reports that in the Netherlands cycling prevents about 6,500 early deaths each year, and that Dutch people have 1.5 years longer life expectancy (预期寿命) due to cycling. 

"The time spent cycling was about 74 minutes per week for Dutch adults aged 20 to 90 years old. The time was fairly stable over adulthood and reached its apex in the early days of retirement, in one's 60s. The death rate reduction, which was a direct result of the average time spent cycling for a certain age group, was therefore also the highest among the seniors who just retired," said Jeremy Smith, an expert from NIH.

What is it that makes cycling so beneficial? Obviously, cycling is a form of exercise. It is a great form of cardio (有氧的) exercise, which gets your heart pumping and helps strengthen the heart muscles. Doing cardio exercise may also help lower your blood pressure. 

Furthermore, solid evidence proves the link between cycling and better thinking skills. Even younger adults claim that a bike ride helps shift their thinking to a higher level — and research backs them up. In one small study, young men are required to cycle for 30 minutes every day for 3 weeks. They also completed a series of cognitive (认知的) tests before and afterward. After cycling, they scored higher on memory, reasoning and planning, and they were able to finish the tests more rapidly than before.

Besides all the benefits mentioned above, cycling, as many Dutch put it, is a way of life. In their simplest form, bikes are tools for travelling. But they're so much more. They are cognitive improvement, environmental protection, satisfaction and an expression of freedom. They bring people of the same passion together and connect them to a greater journey of life.
