Danielle Steel, America's sweetheart, is one of the hardest working women in the book business. Unlike other productive authors who write one book at a time, she can work on up to five. Her research before writing takes at least three years. Once she has fully studied her subjects, ready to dive into the book, she can spend twenty hours nonstop at her desk.

    Danielle Steel comes from New York and was sent to France for her education. After graduation, she worked in the public relations and advertising industries. Later she started a job as a writer which she was best fit for. Her achievements are unbelievable: 390 million copies of books in print, nearly fifty New York Times best-selling novels, and a series of "Max and Martha" picture books for children to help them deal with the real-life problems of death, new babies and new schools. Her 1998 book about the death of her work shot to the top of the New York Times best-selling list as soon as it came out. Twenty-eight of her books had been made into films. She is listed in the Guinness Book of World Records for one of her books being the Times best-seller for 381 weeks straight.

    Not satisfied with a big house, a loving family, and a view of the Golden GateBridge, Danielle Steel considers her readers to be the most important resource and has kept in touch with them by e-mail. While she is often compared to the heroines of her own invention, her life is undoubtedly much quieter. But, if she does have anything in common with them, it is her strength of will and her inimitable (独特的) style. There is only one Danielle Steel.

    Whenever we talk about holidays, my mother teases my sister and me about how we “make out like robbers.” She is referring to the fact that we are half Jewish and half Indian, so we receive gifts on both the festivals of lights: Hanukkah and Diwali. Though my mother teases us, I do not mind getting two sets of gifts!

    Hanukkah is celebrated on the 25^th day of the Jewish month, which is usually sometime in December. On Hanukkah, like most Jewish families, we light a menorah and say a prayer each night. We also say a special prayer on the first night. After that, it is a tradition for my sister and me to do 'hot and cold' for our hidden Hanukkah gifts. When we walk towards the gift, our parents say 'hot' and when we walk further away, they say 'cold'. We each receive one present every night of Hanukkah. Another part I like about this holiday is seeing family members who we do not see often. My aunt usually stays for a few days, and we sometimes visit other relatives.

    Diwali is celebrated on the 13^th day of the dark fortnight of the month of Ashwin (October/November). To celebrate Diwali, my family does a pooja, or prayers, in honor of the goddess Lakshmi. Since she is the goddess of wealth and prosperity, the pooja includes washing silver coins in milk and water. In India, people decorate their houses with lamps, similar to the way you might light up your house for Christmas. My family just places a few candles outside. We also set off firecrackers, which is my favorite part. We often do this activity with friends to add to the excitement.

    Both holidays have different histories and stories. We celebrate them in different ways, yet they both have the same meaning. They both translate into Festival of Lights, and they both mean family and presents for me!

    Many people go to school for an education. They learn languages, history, geography, physics, chemistry and mathematics. Others go to school to learn a skill so that they can make a living. School education is very important and useful. Yet no one can learn everything from school. A teacher, no matter how much he knows, cannot teach his students everything they want to know. The teacher's job is to show his students how to learn. He teaches them how to read and how to think. So, much more is to be learned outside school by the students themselves.

    It is always more important to know how to study by oneself than to memorize some facts or a formula （公式）. It is usually quite easy to learn a certain fact in history or a formula in mathematics. But it is very difficult to use a formula in working out a maths problem. Great scientists, such as Einstein, Newton and Galileo didn't get everything from school. But they were all so successful. They invented so many things for mankind.

Above all, they knew how to use their brains.

    A telescope, called Gaia, is being designed by astronomers in Europe, and it couldn't be more different from Pan-STARRS, which is another telescope being designed. While Pan-STARRS will be looking for asteroids (小行星) and comets headed for Earth, Gaia will be looking at our entire galaxy (银河系).

    Gaia is designed to draw a map of the Milky Way, our home galaxy. Just as a map of your town gives you a picture of where things are located, Gaia's map of the galaxy will tell astronomers where the stars are. Over five years, Gaia will observe (观察) about a billion stars and other objects in our galaxy. Each object will be observed about 70 times.

    Gaia will be sent into space connected to a rocket. It contains two telescopes, each focused at a different angle (角度). These two telescopes act like Gaia's “eyes”. The reason why humans can see things in 3D is that we have two eyes focused on the same object, at slightly different angles. By using two telescopes like eyes, Gaia can produce the first 3D map of the positions of the stars it views.

    Gaia, which is to be sent into space, will be a powerful telescope. If you were to use it on Earth, for example, you could stand 600 miles away from your best friends and still get a clear picture of their hair.

    Gaia is one of more than a dozen telescopes being designed by scientists right now. The next generation of telescopes will reveal new parts of our universe that will seem surprising. The universe, with all its planets, stars and other strange objects, is a puzzle with pieces that we can see by using powerful telescopes.

    The traditional British pub is part of the scenery of British life. At the last count, there are around 50,000 of them in the UK. The oldest – Ye Olde Fighting Cocks in St. Albans – was set up in about 793.

    Because of their abundance, the names pubs take are designed to be memorable, but more than that, they are designed to be visual. Outside any traditional pub worthy of its title, you'll find a hanging signboard with an unusual and uncommon illustration(插图) that represents the name of the business. The practice is so well established that even new pubs copy it. But why do they exist at all?

    The first British pub signs were created in the 12^th century and were simple representations of beer containers and other brewing-related equipment used to tell passersby that establishments sold beer. This was Britain in the dark ages, when education was in short supply. Since most of the population was unable to read, pub signs were used to inform would-be customers that they could find a drink inside.

    The earliest uses of pub names would reference the sign directly. People would appoint to meet at "the sign of the Eagle and Child" rather than at "the Eagle and Child".

    Today the tradition remains unchanged largely out of respect for the past, but many pub signs do have some functionality. Remote country pubs often use signboards to point the way to their doors. It's a part of British culture that's rapidly disappearing – more than 20,000 pubs have closed since 1980 – but for now there are still more than enough. You can take a moment to appreciate the history and symbolism behind a pub's sign the next time you see one.

Albert Einstein's 1915 masterpiece "The Foundation of the General Theory of Relativity" is the first and still the best introduction to the subject, and I recommend it as such to students. But it probably wouldn't be publishable in a scientific journal today.

Why not? After all, it would pass with flying colours the tests of correctness and significance. And while popular belief holds that the paper was incomprehensible to its first readers, in fact many papers in theoretical physics are much more difficult.

As the physicist Richard Feynman wrote, "There was a time when the newspapers said that only 12 men understood the theory of relativity. I do believe there might have been a time when only one man did, because he was the only guy who caught on, before he wrote his paper. But after people read the paper a lot understood the theory of relativity in some way or other, certainly more than 12."

No, the problem is its style. It starts with a leisurely philosophical discussion of space and time and then continues with an exposition of known mathematics. Those two sections, which would be considered extraneous today, take up half the paper. Worse, there are zero citations of previous scientists' work, nor are there any graphics. Those features might make a paper not even get past the first editors.

A similar process of professionalization has transformed other parts of the scientific landscape. Requests for research time at major observatories or national laboratories are more rigidly structured. And anything involving work with human subjects, or putting instruments in space, involves piles of paperwork.

We see it also in the Regeneron Science Talent Search, the Nobel Prize of high school science competitions. In the early decades of its 78-year history, the winning projects were usually the sort of clever but naive, amateurish efforts one might expect of talented beginners working on their own. Today, polished work coming out of internships(实习) at established laboratories is the norm.

These professionalizing tendencies are a natural consequence of the explosive growth of modern science. Standardization and system make it easier to manage the rapid flow of papers, applications and people. But there are serious downsides. A lot of unproductive effort goes into jumping through bureaucratic hoops(繁文缛节), and outsiders face entry barriers at every turn.

Of course, Einstein would have found his way to meeting modern standards and publishing his results. Its scientific core wouldn't have changed, but the paper might not be the same taste to read.
