I went through a training program and became a literacy volunteer(扫盲志愿者)last summer. The training I received, though excellent, did not tell me how it was to work with a real student. When I began to discover what other people's lives were like because they could not read, I realized the true importance of reading.

    My first student Marie was a 44-year-old single mother of three. In the first lesson, I found out she walked two miles to the nearest supermarket twice a week because she didn't know which bus to take. When I told her I would get her a bus schedule, she told me it would not help because she could not read it. She said she also had difficulty once she got to the supermarket because she couldn't always remember what she needed. Since she did not know words, she could not write out a shopping list. Also, she could only recognize items by sight, so if the product had a different label(标识), she would not recognize it as the product she wanted.

    As we worked together, learning how to read built Marie's self-confidence, which encouraged her to continue her studies. She began to make rapid progress and was even able to take the bus to the supermarket. After this successful trip, she reported how self-confident she felt. At the end of the program, she began helping her youngest son, Tony, a shy first grader, with his reading. As she described this experience, I was proud of myself as well. I found that helping Marie to build herself-confidence was more rewarding than anything I had ever done before.

    As a literacy volunteer, I learned a great deal about teaching and helping others. In fact, I may have learned more from the experience than Marie did.

    Heading off to college this year? Here are some fashion tips from our experts you should keep in mind：

    Dress to impress: Stylist and business consultant Daniela Smith says, "Girls should keep in mind that your college professors will often be the bridge that connects you to your future career and your classmates will become your professional network. You don't need to dress like you're going to the office, but you should display an ability to properly present yourself with appropriate maturity and confidence, and look put­together."

    Logo mania (品牌狂热症): Wearing the logos of brands aimed at younger customers physically identifies you as part of that age group  so consider the targeted age group of the stores you shop at. It's tempting to load up on logos, especially well­known logos that signify high­end brands. But consider this: college is a time of self­discovery, a chance to develop your own personal style. Instead of wearing logos head to toe, "walking advertisement" style, why not express who you really are?

    Wear real pants: The combination of leggings and baggy shirts is all too common on college campuses. Smith points out that leggings, yoga pants, and sweatpants are entirely unacceptable in public unless you're exercising. Although leggings worn as pants are a common trend among high school and college girls, they are not an appropriate choice for daywear. As a young woman, your style choice should begin to reflect your maturity level. So, get rid of leggings and wear real pants!

    Keep the cute factor to a minimum: Stay away from sweaters and T-shirts with smiling animals, cartoon characters, or Hello Kitty on them. Sure, kittens might be cute, but they're not doing you any favors in the style department. Dressing too cutesy (矫揉造作的) can take years off your look, and not necessarily in a good way!

    Throughout our daily lives, we have known plenty of people and will know more. But how can we tell if someone is trustworthy? In a paper published recently in the Journal of Personality and Social Psychology, researcher gave us the answer.

    The researchers asked 401 adults from the United States to fill out a questionnaire measuring their guilt-proneness (内疚倾向) in different situations as well as several other qualities, and then play a short online game. In this game, Player 1 is given $1, which they can choose to give to Player2. Any money given to Player 2 is then automatically increased to $2.50. Player 2 can then decide whether to keep all of the money or behave in a trustworthy way by returning a portion of the money to Player 1. The researchers found more guilt-prone people were more likely to share the money with Player 1. Actually, in follow-up studies, guilt-proneness predicted trustworthiness better than other personality qualities the researchers measured.

    Why might guilt lead to trustworthy behavior? The researchers found people who were guilt-prone also reported feeling an obligation to act in ethical (合乎道德的) and responsible ways while interacting (互动) with their partners in the game. People who are guilt-prone tend to avoid engaging in behavior that might harm or disappoint others. If they do something bad, guilt encourages them to try to make things right again.

    Then, how can we use this research to ascertain whether someone is trustworthy? "One way to do this might be observe how they respond to experience regret," lead author Emma Levine, assistant professor at the University of Chicago Levine, explains. Another way is to ask them to describe a difficult dilemma they faced in the past, suggests co-author Taya Cohen, associate professor at Carnegie Mellon University. This is particularly effective, Cohen and her colleagues have found, because it allows us to see if they're concerned about the effects their actions have on others.

Blameless

    I was a freshman in college when I met the Whites. They were completely different from my own family, yet I felt at home with them immediately. Jane White and I became friends at school, and her family welcomed me like a long-lost cousin.

    In my family, it was always important to place blame when anything bad happened.

    "Who did this?" my mother would scream about a dirty kitchen.

    "This is all your fault, Katharine," my father would insist when the cat got out or the dishwasher broke.

    From the time we were little, my sister, brothers and I told on each other. We set a place for blame at the dinner table.

    But the Whites didn't worry about who had done what. They picked up the pieces and moved on with their lives. The beauty of this was driven home to me the summer Jane died.

    In July, the White sisters and I decided to take a car trip from their home in Florida to New York. The two older sisters, Sarah and Jane, were college students, and the youngest, Amy, had recently turned sixteen. Proud of having a new driver's license, Amy was excited about practicing her driving on the trip. She showed off her license to everyone she met.

    The big sisters shared the driving of Sarah's new car during the first part of the trip, but when they reached less crowded areas, they let Amy take over. Somewhere in South Carolina, we pulled off the highway to eat. After lunch, Amy got behind the wheel. She came to a crossroads with a stop sign. Whether she was nervous or just didn't see the sign no one would ever know, but Amy continued into the crossroads without stopping. The driver of a large truck, unable to stop in time, ran into our car.

    Jane was killed immediately.

    I was slightly injured. The most difficult thing that I've ever done was to call the Whites to tell them about the accident and that Jane had died. Painful as it was for me to lose a good friend, I knew that it was far worse for them to lose a child.

    When Mr. and Mrs. White arrived at the hospital, they found their two daughters sharing a room. Sarah had a few cuts on the head; Amy's leg was broken. They hugged us all and cried tears of sadness and of joy at seeing their daughters. They wiped away the girls' tears and made a few jokes at Amy as she learned to use her crutches(拐杖).

    To both of their daughters, and especially to Amy, over and over they simply said, "We're so glad that you're alive."

    I was astonished. No blame. No accusations.

    Later, I asked the Whites why they never talked about the fact that Amy was driving and had run a stop sign.

    Mrs. White said, "Jane's gone, and we miss her terribly. Nothing we say or do will ever bring her back. But Amy has her whole life ahead of her. How can she lead a full and happy life if she feels we blame her for her sister's death? "

    They were right. Amy graduated from the University of California and got married several years ago. She works as a teacher of learning-disabled students. She's also a mother of two little girls of her own, the oldest named Jane.

Researchers say they've used cutting-edge gravitational wave research to cast new light on a mystery—a 2000-year-old computer,the Antikythera mechanism found in shipwreck. 

Well over a century after its discovery,researchers at the University of Glasgow say they've used statistical modeling techniques,originally designed to analyze gravitational waves —ripples in spacetime caused by major events in the universe such as two black holes combining —to suggest that the Antikythera mechanism was likely used to track the Greek lunar year. In short,it's a fascinating collision between modern-day science and the mysteries of an ancient artifact. 

In a 2021 paper,researchers found that previously discovered and regularly spaced holes in a "calendar ring"were marked to describe the "motions of the sun,moon,and all five planets known in ancient Greeks and how they were displayed at the front as an ancient Greek universe. "Now,in a new study published in the Official Journal of the British Horological Institute,University of Glasgow gravitational wave researcher Graham Woan and research associate Joseph Bayley suggest that the ring was likely perforated (打孔)with 354 holes, which happens to be the number of days in a lunar year. 

The team used statistical models derived from gravitational wave research,a large-scale physics experiment designed to measure ripples in spacetime millions of light-years from Earth and Bayesian analysis,a technique using probability to quantify uncertainty based on incomplete data,to calculate the likely number of holes in the mechanism using the positions of the surviving holes and the placement of the ring's surviving six fragments. 

Surprisingly,the inspiration for the study came from a YouTuber Chris Budiselic,who has been attempting to physically recreate the ancient mechanism and investigating ways to determine just how many holes it contained. 

"It's a neat symmetry that we've adapted techniques we use to study the universe today to understand more about a mechanism that helped people keep track of the heavens nearly two millennia ago,"Woan said. 

"We hope that our findings about the Antikythera mechanism,although less supernaturally spectacular than those made by Indiana Jones,will help deepen our understanding of how this remarkable device was made and used by the Greeks,"Woan sadded.
