One day, I received a call from a colleague. He was about to give a student a zero for his answer to a physical problem, while the student claimed a perfect score. I was elected as their arbiter（仲裁人）. I read the examination problem: “Show how it is possible to determine the height of a tall building with the aid of a barometer（气压计）. ”The student had answered; "Take the barometer to the top of the building, attach a long rope to it, lower it to the street, and then bring it up, measuring the length of the rope. The length of it is the height of the building.”

    The student had really answered the question completely, but the answer didn't confirm his competence in physics. I suggested the student try again. I gave him six minutes to answer the question, warning that the answer should show some knowledge of physics. Five minutes later, he said he had many answers and dashed off one, which read：“Take the barometer to the top of the building and lean over the edge of the roof. Drop the barometer, timing its fall with a stopwatch. Then, use the physical formula（公式）to calculate the height of the building.”

    At this point, my colleague had to accept it, and then the student made almost full marks. I couldn't help asking the student what the other answers were. He listed many others, and then added, "Probably the best is to take the barometer to the administrator and said to him, ‘Sir, here is a fine barometer. If you tell me the height of the building, I will give it to you.”,

    Then, I asked the student if he really did not know the conventional answer to this question. He admitted that he did, but said that he was fed up with high school and college instructors trying to teach him how to think.

    The name of the student was Bohr who later was famous all over the world. He won the Nobel Prize for Physics in 1922.

    Last Thursday, Michael and Linda stood behind large food trucks distributing meals to 4,000 homeless people for their wedding reception on the border town of Kilis. The couple had decided that instead of hosting their friends and family for a traditional feast reception, they would feed the victims from an earthquake-stricken area.

    The idea came from the bridegroom's father, Ted, who volunteers for a Turkish relief organization. For the past few years, the organization has distributed daily meals to thousands of people who've suffered from natural disasters. He approached a representative of the organization and suggested that the family cover part of the costs of feeding them for the day.

    Then he told his son, who was surprised by the suggestion, but soon won over. When he told that to the bride, she was really shocked but finally accepted because in southeastern Turkey there is a real culture of sharing with people in need. They love to share their food, their table and everything they have. And afterwards she was quite amazed about it. So, they arrived at the distribution center on Thursday to spend the day serving food and taking photographs with their grateful recipients（接受者）．

    On Tuesday evening, the newly married couple were still pleased with their decision to quit a personal celebration for one with a greater good. "It's like sharing a dinner with your friends and family who have this kind of thing on a daily basis or sharing something with people who don't even have the most basic things," Michael said. "Hopefully, this will also give the start for other wedding dinners to be held here with our brothers and sisters in need."

    Do you need help in creating a character for your novel? Well, you have come to the right article.

    Write down your characters full name.

    You can also write down any other name/nickname/title he or she has. Try not to use your name or someone else's name that you know, as this may be considered personal information. You may be writing a mystery and your main character may just be referred to as, for example, the Man, all the way through the novel. Even if in this situation, to add depth to your character, you should know the character inside-out even if the reader will not.

    Describe your character's physical features.

    Does he/she have red or blonde hair? What color is his/her skin? Is he or she a human, animal, robot or imagined creature? Make your character unusual. Describe your character in an interesting way, even if your character is meant to be common or average. The possibilities are vast; just make the descriptive language good, so that it conjures up(使在脑海中显现)the character for the readers.

    Describe the character's personality in detail

    They are all great for working with as a writer, but you must choose a reasonable one that best fits your

Character—don't try to give the character an unlikely combination of many features. Don't give the character merely neutral or good features. Also add the bad habits and weaknesses. Your character is best if presented as defective (in actions, appearance or personality).Your character can make mistakes, have bad habits, and have little interesting strange habits. This is what makes the character interesting.

    Work out a good plot.

    What is a good story without a good plot? Maybe your character has become mixed up with some bad people or a strange mystery. Maybe your character has only months to live and wants to do something great

    But, the plots must be connected to the character. Keep imagining.

    You've heard of the fat suit and the pregnancy suit; now meet AGNES—the old person suit.

    AGNES stands for “Age Gain Now Empathy(换位体验)System” and was designed by researchers at MIT's AgeLab to let you know what it feels like—physically—to be 75 years old. “The business of old age demands new tools,” said Joseph Coughlin, director of the AgeLab. “While focus groups and observations and surveys can help you understand what the older consumer needs and wants, young marketers never get that Ah ha! moment of having difficulty opening a jar, or getting in and out of a car. That's what AGNES provides. ”

    Coughlin and his team carefully adjusted the suit to make the wearer just as uncomfortable as an old person who has spent a lifetime eating poorly and not doing much exercise. Special shoes provide a feeling of imbalance, while braces on the knees and elbows limit joint mobility. Gloves give the feeling of decreased strength and mobility in the hands and wrists, and earplugs make it difficult to hear high—pitched sounds and soft tones. A helmet with straps(带)attached to it presses the spine(脊柱), and more straps attached to the shoes decrease hamstring flexibility, and shortens the wearer's step.

    AGNES has been used most recently by a group of students working on a design of an updated walker. By wearing the suit they could see for themselves what design and materials would make the most sense for a physically limited older person. Coughlin said the suit has also been used by clothing companies, car companies and retail goods companies to help them understand the limitations of an older consumer.

    “AGNES is not the destiny of everybody,” he said. “She is a badly behaved lady who didn't eat and exercise very well. A secondary benefit we've found with AGNES is that it has become a powerful tool to get younger people to invest in their long-term health. ”

Darrion Cockrell,who wasn't much of a student,has been named Missouri's Teacher of the Year—the state's highest honor for educators,becoming the first male since 2015 to capture the state's top award.

Cockrell—the child of "a drug-addicted mother" and a father who was killed when he was four years old—was in and out of the childcare centers and eventually became a gang (帮派) member.In his speech,he shouted out the special people who helped to guide him down the right path when he was going off track.

He thanked his teacher Ken who provided him with life advice while he lived in a boys' group home."He taught me it's OK to be tough,but at the same time,it's OK to be compassionate (富有同情心的),"Cockrell said."He was like a father figure to me."

The teacher—affectionately known as "DC"—also expressed his gratitude to the football coach that adopted him when he was in the 7th grade and helped to change his whole perspective (视角) on life."When I changed the way I looked at things,the things around me started to change,"he said."I had a lot of struggles and a lot of hurdles,and if not for those educators,I would not be here today."

Now,Cockrell hopes to make an impact on the students at Lindbergh Schools' Crestwood Elementary in St.Louis,where he's been teaching physical education since 2015.Among his many accomplishments at the school is his development of the"Crest-Fit"training program for teachers,students and parents.

"Missouri is fortunate to have so many high-quality educators,and Darrion will be a wonderful representative as our state's Teacher of the Year,"Commissioner of Education Margie Vandeven said in a statement."He guides his students towards long-term physical and mental wellness,and the connections he has established will impact Crestwood children for years to come."

Many people have long believed that bright lights draw, or attract flying insects. But that is not exactly what is going on, a new study suggests.

Researchers believe that artificial lights at night may cause problems with flying insects' natural navigation systems. As a result, the creatures fly in confusion around porch lamps, street lights and other artificial lights. "Insects have a navigational problem," said Tyson Hedrick of the University of North Carolina, Chapel Hill. He added, "They're accustomed to using light as a cue（提示）to know which way is up."

Insects do not fly directly toward a light source, but actually "tilt（倾斜）their backs toward the light," said Sam Fabian of Imperial College London. Fabian was a co-writer of the study that appeared recently in Nature Communications. This tilting action would make sense if the strongest light source was in the sky. But in the presence of artificial lights, the result is midair confusion.

For the study, researchers attached very small sensors to moths and dragonflies in a laboratory. They then filmed "motion-capture" video of flight—similar to how filmmakers attach sensors to actors to follow their movements. Researchers also used high-resolution cameras to film insects flying around lights at a field in Costa Rica. Such films permitted researchers to study in detail how dragonflies circle endlessly around light sources, positioning themselves with their backs facing the light. Researchers also documented that some insects fly upside down—and often crash land—in the presence of lights that shine straight upward like search lights. Insect flight was least disrupted by bright lights that shine straight downward, the researchers found.

"For millions of years, insects oriented themselves by sensing that the sky is light, the ground is dark—until people invented artificial lights", said Avalon Owens of Harvard University.
