    When asked about happiness, we usually think of something extraordinary, an absolute delight, which seems to get rarer the older we get.

For kids, happiness has a magical quality. Their delight at winning a race or getting a new bike is unreserved (毫无掩饰的).

    In the teenage years the concept of happiness changes. Suddenly it's conditional on such things as excitement, love and popularity. I can still recall the excitement of being invited to dance with the most attractive boy at the school party.

    In adulthood the things that bring deep joy—love, marriage, birth—also bring responsibility and the risk of loss. For adults, happiness is complicated (复杂的).

    My definition of happiness is “the capacity for enjoyment”. The more we can enjoy what we have, the happier we are. It's easy to overlook the pleasure we get from the company of friends, the freedom to live where we please, and even good health.

    I experienced my little moments of pleasure yesterday. First I was overjoyed when I shut the last lunch-box and had the house to myself. Then I spent an uninterrupted morning writing, which I love. When the kids and my husband come home, I enjoyed their noise after the quiet of the day.

    Psychologists tell us that to be happy we need a mix of enjoyable leisure time and satisfying work. I don't think that my grandmother, who raised 14 children, had much of either. She did have a network of close friends and family, and maybe this what satisfied her.

    We, however, with so many choices and such pressure to succeed in every area, have turned happiness into one more thing we've got to have. We're so self-conscious about our “right” to it that it's making us miserable. So we chase it and equal it with wealth and success, without noticing that the people who have those things aren't necessarily happier.

    Happiness isn't about what happens to—it's about how we see what happens to us. It's the skillful way of finding a positive for every negative. It's not wishing for what we don't have , but enjoying what we do possess.

    Many years ago, people relied on the sun, the moon and stars to find their way around. Later, the compass was introduced. And now, we have satnav（卫星导航）systems to guide us. A satnav system uses groups of satellites to show the user's location. They send information to a receiver, such as a smart phone, to show us where we are.

    The earliest built satnav system is the Global Positioning System, which belongs to the US. Then there is Russia's Global Navigation（导航）Satellite System, the European Union's Galileo and China's own satellite navigation system, BeiDou.

    On October 14, 2017, an ARJ21-700 plane, which was the first domestically-produced jet equipped with the BeiDou navigation system, successfully completed a test flight. The results showed the performance of the system developed by China matches that of similar systems produced abroad, according to the Commercial Aircraft Corporation of China.

    Since its introduction in 2000, the Beidou navigation system has seen increasing numbers of applications linked to everyday life, from shared bikes to farming.

    When it comes to shared bikes, smart locks that support BeiDou chips offer more accurate positioning than others, making it easier to find a bike.

    Farmers can use BeiDou-enabled tractors to plow（犁）the soil and use unmanned aircraft with BeiDou to sow seeds, which can improve efficiency and make better use of resources. BeiDou's farming applications have spread from Heilongjiang province to Beijing, Liaoning, Shanxi, Hubei and other regions across China.

    With its many uses, the Beidou navigation system is even playing a big role in the Belt and Road Initiative（— 带—路）. “To date, the BeiDou system has covered most parts of the Asia-Pacific region, as well as counties along the Silk Road Economic Belt and the 21^st Century Maritime Silk Road” said Yang Changfeng, Chief designer of the BeiDou system.

    Today, there are more than 20 BeiDou satellites above our heads, and China plans to launch even more this year to expand the BeiDou network to better serve the Belt and Road Initiative.

    “As BeiDou expands its overseas reach, it will be increasingly popular in the logistics （物流）industry,” said Miao Qianjun, secretary-general of the navigation services association. “Ships, for example, can use it to position themselves while sailing across oceans to European countries, no longer limited to Southeast Asian regions in the near future.”

    Mark felt that it was time for him to take part in his community，so he went to the neighborhood meeting after work. The area city council(委员会)woman was leading a discussion about how the quality of life was on the decline. The neighborhood faced many problems. Mark looked at the charts taped to the walls. There were charts for parking problems, crime, and for problems in vacant buildings. Mark read from the charts, “Police patrols(巡逻)cut back, illegal parking up 20%.” People were supposed to suggest solutions to the council woman. It was too much for Mark. “The problems are too big,” he thought. He turned to the man next to him and said, “I think this is a waste of my time. Nothing I can do would make a difference here.”

    As he neared the bus stop on his way home, Mark saw a woman carrying a grocery bag, and a baby. As Mark got closer, her other child，a little boy, suddenly dashed into the street. The woman tried to reach for him, but as she moved, her bag shifted(滑落), and groceries started to fall out.Mark ran to take the boy's arm and led him back to his mother. “You gotta stay with Mom,” he said. Then he picked up the fallen groceries while the woman smiled in relief. “Thanks,” she said. “You've got great timing.” “Just being neighborly,” Mark said. As he rode home, he glanced at the poster near his seat in the bus. Small acts of kindness add up.Mark smiled and thought, “Maybe that's a good place to start.”

    A story posted by The New York Post Monday tells the tale of Katrina Holte, a Hillsboro woman who quit her job to cosplay a 1950s housewife.

    Let me start by expressing admiration to Holte for using her 2019 freedoms to follow her 1950s dreams. Everyone should be so lucky as to get to decide what they wear and how they spend their time. That's the future our foremothers fought for.

    But as much fun as I am sure she is having living a vintage (复古的) life, which literally includes watching shows like "I Love Lucy" and listening to vinyl recordings (刻录碟片), I think it's important to remember that being a 1950s housewife was actually totally awful, and something our grandmothers and mothers fought against.

    For example, once I called my grandma and asked her for her recipe for Cloud Biscuits, these delicious biscuits she used to make that we would cover with butter and homemade raspberry jam on Thanksgiving.

    "Why would you want that?" she said. "Go to the store. Go to the freezer section. Buy some pre-made biscuits and put them in the oven."

    She straight-up refused to give me the recipe, because it was hard and took a long time to make. In her mind, it was a waste of time.

    Getting off the phone, it occurred to me that spending every day of your life serving a husband and five children wasn't fun at all. And then there are the grandchildren who eventually come along demanding Cloud Biscuits, a whole new expanded set of people to feed.

    She was basically a slave to those hungry mouths, cooking scratch meals three times a day.

    When she wasn't trapped in the kitchen, she had to keep the house clean, make sure she looked good enough to be socially acceptable, and make sure her kids and husband looked good enough to be socially acceptable. And she had no days off.

    I know my grandma loves her kids and her grandkids, her husband and the life she led, but man, it must have been a lot of thankless, mindless labor.

    No wonder everyone went all-in on processed foods when they came around. Imagine the nice break something like a microwave dinner would give a woman working, unpaid, for her family every single day?

    I also had another grandma. She was a scholar who helped found the Center for the Study of Women in Society at University of Oregon. She was a pioneering second-wave feminist who wrote books, gave lectures and traveled the world.

    But, she did all of that after divorcing my grandpa, when most of her kids were out of the house. Back then, in the 1950s and the 1960s, there was no illusion about women "having it all". How could that even possibly happen? If you were taking care of a family, waiting on your husband, you had no time to follow your dreams, unless you made that your dream.

    A lot of women took that approach. We call it Stockholm Syndrome now.

    And of course, these women I am talking about are upper-middle-class white women. Romanticizing the 1950s is especially disgusting when you think about how women of color and poor women were treated back then, and the lack of education and choices available to them.

    Because the women in this country demanded something approaching equality, Holte has the chance to live out her fantasy. Not every woman in America is so lucky.

    We still don't have pay equality and in many states, we still don't have autonomy over our own bodies. Poor women and women of color still lack the opportunities of their wealthy and white peers.

    And while it's getting better, women are still expected to be responsible for the emotional labor of running a household and raising the children.

    But at least we can get jobs. At least we don't have to sew our own clothes, wear a full face of makeup every day and spend hours making Cloud Biscuits some ungrateful kid will wolf down, barely remembering to say thank you.

Have you ever heard of invisible ink? You may have seen it in movies. When light is shone on the paper which invisible ink is written on, you can read it!

As magical as this seems, the change in color is due to science. The ink is absorbing higher energy light and giving lower energy light. This reaction is an example of fluorescence (荧光) .

Light is a very broad term that describes a range of electromagnetic rays, including gamma rays, infrared light (红外光) and ultraviolet light. One part of the electromagnetic visible light is the colors that we can see with the human eye. These rays travel in curvy lines and each type of the ray is characterized by a different wave pattern. For example, Gamma rays have a shorter wavelength than infrared light. Shorter wavelength is connected with higher energy, so gamma rays also have more energy than infrared light.

Corals (珊瑚) are animals that live underwater. And the corals in the Red Sea exhibit fluorescence. Why is this happening? Scientists have shown that fluorescent objects absorb higher energy light and release lower energy light. Since the corals of the Red Sea are deep in the water where there is very little visible light, scientists theorize that these corals absorb ultraviolet light and produce visible light. They have special photo proteins, which enable them to change invisible light to visible light.

Fluorescence is not just used to create pretty colors. Corals have developed photo proteins for a biological reason. The visible light is used by algae (海藻) , which are eaten by the coral, to make food through photosynthesis (光合作用). The visual character of these photo proteins could also be used for biomedical research. They can highlight cells and cell structures under a microscope.

Isn't it amazing that a simple organism that we don't think very much of is not only grand but could also have so many potential uses in medical research!
