Some people may think I'm crazy when I say “work is rest”. But that's the way it is — we need to rest. Without rest, we will die. At a minimum, we won't have the energy to work.

    Nobody forces us to be so stupid about this. We just don't know how to rest properly. We rest in ways that are not restful, even stressful. Some of our ways of rest interfere with our working energy. Instead of sleep, we go to the movies and clubs, drink or have a smoke with friends. This is because we misunderstand the meaning of “rest”.

    We should remember that rest means not working, both physically and mentally. Only then is it real rest. When tired, rest. It's simple. Actually, dogs and cats are smarter about this than people. People are stupid enough to rest in ways that destroy their capacity to work.

    Rest and work always go together. There must be a balance: work during the day and rest at night. When the sun comes up, one has plenty of strength to work well and enjoy it. In other words, rest is a kind of investment, so that one has the strength and energy to continue working. So we need rest to work, recognizing that we can't have one without the other. Rest is what recharges our batteries. We need enough time to charge up adequately to the tasks we undertake. Thus, we need to rest correctly; otherwise, illness will occur and also can affect the efficiency of our work.

    Rest can't be skimped. Without enough rest, good work is impossible. This is why we say that rest is another kind of work.

    So you want to be a citizen scientist? The National Science Foundation (NSF) has got you covered. NSF supports citizen science across all areas of science, whether your passion is to scan the night sky, or explore your own backyard.

Join a flock of birders

    eBird is an online platform that allows bird-watchers to go online and record their sightings to a database. With more than 100,000 active users, eBird's system is a treasure of information on bird population, distribution and habitat, which users can explore in real time.

Count every drop

    The Community Collaborative Rain, Hail and Snow Network (CoCoRaHS) is the largest provider of daily precipitation observations in the United States. Volunteers set up rain gauges and record data every time a rain, snow or hail storm passes over. Data is organized and shared on the CoCoRaHS website, and used by scientists, farmers and more.

Search for stars with your computer

    Einstein@Home uses your computer's idle time to search for space signals. The project has already had major successes: Volunteers discovered about 50 stars, using data from Puerto Rico's Arecibo Observatory and Australia's Parkes Observatory. Einstein@Home also searches for gravitational-wave signals using data from NSF's Laser Interferometer Gravitational Wave Observatory.

Be part of a supercomputer

    To link all those home computers, Einstien@Home uses software called the Berkeley Open Infrastructure for Network Computing, better known as BOINC. The software choreographs(安排，筹划) the technical aspect of volunteer computing and helps you use radio telescope signals to search for alien life.

Join the plankton party

    Without plankton, life in the ocean would not exist. These tiny organisms form the base of the food chain, and play an important role in the global carbon cycle. Plankton Portal enlists citizen scientists to identify images of plankton, snapped by the In Situ Icthyoplankton Imaging System (ISIIS), an underwater robot engineered at the University of Miami. ISIIS has taken millions of images in oceans around the world and upload them into a database; classifying the images helps researchers understand plankton diversity, habitat and behavior.

    A city child's summer is spent in the street in front of his home, and all through the long summer vacations I sat on the edge of the street and watched enviously the other boys on the block play baseball. I was never asked to take part even when one team had a member missing—not out of special cruelty, but because they took it for granted I would be no good at it. They were right, of course.

    I would never forget the wonderful evening when something changed. The baseball ended about eight or eight thirty when it grew dark. Then it was the custom of the boys to retire to a little stoop(门廊) that stuck out from the candy store on the corner and that somehow had become theirs. No grownup ever sat there or attempted to. There the boys would sit, mostly talking about the games played during the day and of the game to be played tomorrow. Then long silences would fall and the boys would wander off one by one. It was just after one of those long silences that my life as an outsider changed. I can no longer remember which boy it was that summer evening who broke the silence with a question: but whoever he was, I nod to him gratefully now. “What's in those books you're always reading?” he asked casually. “Stories,” I answered. “What kind?” asked somebody else without much interest.

    Nor do I know what drove me to behave as I did,for usually I just sat there in silence, glad enough to be allowed to reain among them; but instead of answering his question, I told them for two hours the story I was reading at the moment. The book was Sister Carrie. They listened bug-eyed and breathless. I must have told it well, but I think there was another and deeper reason that made them to keep an audience. Listening to a tale being told in the dark is one of the most ancient of man's entertainments, but I was offering them as well, without being aware of doing it, a new and exciting experience.

    The books they themselves read were the Rover Boys or Tom Swift or G.A.Henty. I had read them too, but at thirteen I had long since left them behind. Since I was much alone I had become an enthusiastic reader and I had gone through the books-for-boys series. In those days there was no reading material between children's and grownups'books or I could find none. I had gone right fromTome Swift and His Flying Machine to Theodore Dreiser and Sister Carrie. Dreiser had hit my young mind, and they listened to me tell the story with some of the wonder that I had had in reading it.

    The next night and many nights thereafter, a kind of unspoken ritual (仪式) took place. As it grew dark, I would take my place in the center of the stoop and begin the evening's tale. Some nights, in order to taste my victory more completely, I cheated. I would stop at the most exciting part of a story by Jack London or Bret Harte, and without warning tell them that that was as far as I had gone in the book and it would have to be continued the following evening. It was not true, of course; but I had to make certain of my new-found power and position. I enjoyed the long summer evenings until school began in the fall. Other words of mine have been listened to by larger and more fashionable audiences, but for that tough and athletic one that sat close on the stoop outside the candy store, I have an unreasoning love that will last forever.

    When my father married my mother in 1943, he gave my mother a 1937 crown coin and told her to keep it in the back of her purse and not to spend it. This would mean that she always felt that she was protected and would always have money if she really needed it.

    When I was married in 1970 my husband who had heard this story, obtained a 1937 crown coin for me and I have always kept it in my wallet, and I have always had enough for my needs.

    A friend recently fell on hard times, partly through external (外部的) circumstances and partly through poor planning. Friends and I have loaned her money, paid her bills, given her food, and even tried to teach her budget techniques, but none of them has been a solution. She has just slipped deeper and deeper into financial trouble and depression.

    Last week she looked pale and unwell, very depressed and hopeless, very sad for a friend to see and I then thought about how the crown coin, a physical reminder of another's care and love had protected me, so I went to the bank for a $ 100 dollar-bill.

    I told my friend the story and asked her to keep the $ 100 in the back of her wallet. It turned out that she didn't have a wallet, so she put the money in a little pencil case where she kept her coins. She immediately felt better—"I feel rich, and thank you for being a good friend," she said, and we were both a bit teary.

    I went home and remembered a little wallet I had that I'd never used, and thought, "I'll give that to my friend." I opened it, and inside, found $ 100.

    Do you know the term "tweenager"? It's a slang word being used in the UK to describe children 10-13 years old. They are between junior and the teenage years. Why are they suddenly referred to in this way?

    Tweenagers now have more money, freedom and influence upon their parents than they've ever had before. More and more companies are creating products and services for tweenagers. You can get everything from branded lunchboxes and mobile phone covers, to monthly fan magazines and clothing-it's all about sales.

    Most children in the UK today get more pocket money than kids did a decade ago. It is because parents are having fewer children on average than in the past. In addition, the divorce rate in the UK is continually rising and parents spend less time with their children than they used to. So, many parents try to compensate(补偿) by buying presents for them.

    And do tweenagers have more freedom? Well, UK children today are very familiar with media and computer. Many have a television, if not a computer, in their bedrooms. They have access to much more information about the world.

    They may have experienced a lot in life as well, since 24% of UK kids live in single-parent families. People now say that "Kids are getting older younger". With such sophistication (世故) at such a young age, they are much more fashion conscious and concerned about their image.

    In a world of TV programs that promise overnight success and fame at a young age, some people think it's extremely important to look fashionable. Surely none of the above is a good thing, is it? Can it really be healthy for us to encourage kids to be like adults at such a young age? Are we stealing childhoods in return for profit?

    The UK government is certainly concerned, and for that reason has strict laws preventing companies from marketing their products and services at children. So, is there a happy ending to this story?

    Companies have just worked out that the older tweenage audience is now looking for something darker and more rebellious. As a result, films such as Twilight are being produced for this older tweenage audience.

Ramirez Castañeda, a Colombian biologist, spends her time in the Amazon studying how snakes eat poisonous frogs without getting ill. Although her findings come in many shapes and sizes, she and her colleagues have struggled to get their biological discoveries out to the wider scientific community. With Spanish as her mother tongue, her research had to be translated into English to be published. That wasn't always possible because of budget or time- and it means that some of her findings were never published.

" It's not that I'm a bad scientist," she says." It's just because of the language."

Castañeda is not alone. There is plenty of research in non- English- language papers that gets lost in translation, or is never translated. A research looked through more than 400, 000 peer- reviewed papers in 16 different languages and found 1,234 studies providing evidence on biodiversity conservation which, because they weren't in English, may have been overlooked. These included Japanese- language findings on the effectiveness of relocating the endangered Blakiston's fish owl, the largest owl species.

Some experts argue that for the sake of the bigger picture, scientific knowledge should converge(转换) into one common language. Science is very globalised and becoming more so, so the use of a global language is enormous for that.

Of course, scientists can work with an English partner, or use a translator- but this ultimately strengthens the cycle of dependency on the global north, leading to inequality in international influence. The specific meanings of words can also pose a problem in translation. For example, it is difficult to find in English one single word to describe forest snakes and frogs in the work Castafieda does with indigenous(土著的) communities in the Amazon.

" So we' re losing observations for science, too," says Castañeda." For me, it's not possible to just have everything translated into English. We need multilingual(多语种的) science, and we need people that feel comfortable doing science in their own languages. It could be possible to switch to a world where, say, Chinese, English and Spanish are the three languages of science, just as English, French and German were the languages of science in the 19th century."
