Next time a customer comes to your office, offer him a cup of coffee. And when you're doing your holiday shopping online, make sure you're holding a large glass of iced tea. The physical sensation（感觉）of warmth encourages emotional warmth, while a cold drink in hand prevents you from making unwise decisions—those are the practical lesson being drawn from recent research by psychologist John A. Bargh.

    Psychologists have known that one person's perception（感知）of another's “warmth” is a powerful determiner in social relationships. Judging someone to be either “warm” or “cold” is a primary consideration, even trumping evidence that a “cold” person may be more capable. Much of this is rooted in very early childhood experiences, Bargh argues, when babies' conceptual sense of the world around them is shaped by physical sensations, particularly warmth and coldness. Classic studies by Harry Harlow, published in 1958, showed monkeys preferred to stay close to a cloth “mother” rather than one made of wire, even when the wire “mother” carried a food bottle. Harlow's work and later studies have led psychologists to stress the need for warm physical contact from caregivers to help young children grow into healthy adults with normal social skills.

    Feelings of “warmth” and “coldness” in social judgments appear to be universal. Although no worldwide study has been done, Bargh says that describing people as “warm” or “cold” is common to many cultures, and studies have found those perceptions influence judgment in dozens of countries.

    To test the relationship between physical and psychological warmth, Bargh conducted an experiment which involved 41 college students. A research assistant who was unaware of the study's hypotheses（假设）, handed the students either a hot cup of coffee, or a cold drink, to hold while the researcher filled out a short information form: The drink was then handed back. After that, the students were asked to rate the personality of “Person A” based on a particular description. Those who had briefly held the warm drink regarded Person A as warmer than those who had held the iced drink.

    “We are grounded in our physical experiences even when we think abstractly,” says Bargh.

    If you live in the U.S., you're probably used to throwing banana peel into the trash. But people in other countries, including India, have been taking advantages of their nutritional benefits for many years.

    While the flesh of a banana is soft and sweet, the skin is thick, hard and slightly bitter. To eat the peel, you can fry, bake, or boil it for at least 10 minutes. Also, the riper bananas get, the thinner and sweeter banana peel will become. That's because of a natural plant hormone(激素) called ethylene(乙烯) that fruits release as they ripen. Ethylene interacts with the sugars and fiber in the banana skin, changing complex sugars into simple sugars and breaking down pectin, a form of fiber in bananas that keeps them stiff. That's why the older your banana is, the flimsier(不结实的) it feels.

    The sweet flesh of a medium-sized banana contains great percentages of your daily recommended intake of various nutrients, such as:

·12% of your daily fiber, which helps with digestion and may help lower your risk of diabetes(糖尿病)

·17% of your vitamin C, which is important for your immune system as well as your growth

·20% of your vitamin B6, which aids the body's ability to turn food into energy

·12% of your potassium, which helps with the development of cells, tissues, and organs throughout the body

    If you eat the skin along with the flesh, you will get an even bigger increase in these same nutrients.

    Eating the peel is not only good for your body but also better for the earth. The average American ate 11.4 pounds of bananas in 2014. Since a medium-sized banana weighs about 0.3 pounds, that equates to about 38 bananas per person, or about 12 billion for the whole of the U.S. And since most of us throw away the peel, that also means a lot of organic waste.

    Pastime is a bi-monthly magazine for curious young minds. Many of the topics we write about won't be covered in the classroom. All the articles are written in a lively style, and each one is paired with drawings by some of the country's most talented artists.

    History focuses on archaeological (考古的) sites around the world where archaeologists work to unearth important finds.

    World includes stories about daily life, folk tales, and history and traditions of the people and places.

    Sport includes nutrition tips, information about up-and-coming young athletes, and sports events.

    Art stimulates a child's cultural life, from film to theatre through to writing and music.

    On top of all that, Pastime is packed with items to stimulate a youngster's imagination, including pages of puzzles and a step-by-step guide to creating their own impressive-looking drawings.

    In every issue, we review the latest books top authors write for youngsters. There are also short works of fiction written especially for Pastime by some of our best writers.

    We know that children at this age are dealing with many emotions and sometimes difficult feelings, so we have a personal advice page to reply to questions dealing with personal and moral problems.

    Unlike many of today's throwaway comics, Pastime is written and designed to be kept and treasured. We know children love going online — but we also know how much they enjoy holding a printed magazine in their hands, and the excitement they get when each new issue drops through the letterbox personally addressed to them.

    Subscription

    Pastime is published six times a year. An annual subscription costs just £20 and makes a great gift for any child aged eight to twelve.

    Visit the Newseum During "Museum Day"！

    Museum Day is an annual celebration of boundless curiosity hosted by Smithsonian magazine. Participating museums and cultural institutions across the country provide free entry to anyone presenting a Museum Day ticket. The Museum Day ticket provides free admission for two people.

    Here is some information about a popular museum — the Newseum.

    EVENT DETAILS

    Registration: free tickets will be available for the public to download on December 15 via the link: https://www.smithsonianmag. com/museumday/museum-day-2018/.

    Advanced registration is requested so that the museum sites know how many people to expect. If you don't register beforehand you may still be admitted the day of the event, but no guarantee for admission. All are welcome to attend including children and groups.

    Meeting Point #1: From 7:45 – 8:00 some volunteers will be in the Starbucks at 325 7th St NW before walking 2 blocks to the Newseum.

    Meeting Point #2: Outside the Newseum's Pennsylvania Avenue entrance. The Newseum opens at 9:00 am. However, as this is an extremely popular event we highly recommend arriving as early as possible, by 8:15 if you can, to bypass the masses that will show up later in the day.

    Meeting Point #3: Once the museum opens we recommend immediately heading to the 6th floor to avoid the masses since most people start on the 1st floor. On the 6th floor, the Hank Greenspun Terrace, which overlooks Pennsylvania Avenue and the U. S. Capitol, has one of the best views in Washington, DC. After that you can proceed through the museum's exhibits starting on the 6th floor and working our way down. The Newseum is open until 5:00 pm and guests are free to arrive and depart whenever they like.

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.
