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.

    I arrived at my mother's home for our Monday family dinner. The smells of food flew over from the kitchen. Mother was pulling out quilt (被子) after quilt from the boxes, proudly showing me their beauties. She was preparing for a quilt show at the Elmhurst Church. When we began to fold and put them back into the boxes, I noticed something at the bottom of one box. I pulled it out. “What is this?” I asked.

    “Oh?” Mom said, “That's Mama's quilt.”

    I spread the quilt. It looked as if a group of school children had pieced it together; irregular designs, childish pictures, a crooked line on the right.

    “Grandmother made this?” I said, surprised. My grandmother was a master at making quilts. This certainly didn't look like any of the quilts she had made.

    “Yes, right before she died. I brought it home with me last year and made some changes, she said. “I'm still working on it. See, this is what I've done so far.”

    I looked at it more closely. She had made straight a crooked line. At the center of the quilt, she had stitched (缝) a piece of cloth with these words: “My mother made many quilts. She didn't get all lines straight. But I think this is beautiful. I want to see it finished. Her last quilt.”

    “Oh, this is so nice, Mom,” I said. It occurred to me that by completing my grandmother's quilt, my mother was honoring her own mother. I realized, too, that I held in my hands a family treasure. It started with the loving hands of one woman, and continued with the loving hands of another.

    If a trip to Rome or Paris is in your future, be prepared: The European Union Parliament is calling for an end to visa-free travel Americans. EU lawmakers passed a resolution urging the EU Commission to impose visas on U. S. citizens traveling into the 28-nation bloc.

    The dispute(争论)centers on reciprocal treatment of travelers from EU nations and the United States. While Americans have been able to travel throughout EU member nations without a visa, the U. S. still requires citizens of five EU countries-Bulgaria, Croatia, Cyprus, Poland and Romania-to apply for entry visas when visiting the U. S, Reuters reports. Citizens of the other 23 EU member nations can use the U. S. visa waiver program to enter America. The EU lawmakers are calling for mutual treatment for all EU citizens, says Reuters. They've given the EU Commission two months to respond.

    The trans-Atlantic visa dispute first came to light in April 2014, according to an EU Parliament news release. At that time, five countries-Australia, Brunei, Canada, Japan and the U. S. –required visas for some EU citizens. Since then, Australia, Brunei and Japan have lifted their visa requirements for all EU citizens. Canada, which currently imposes(推行)visa requirements on Bulgarian and Romanian citizens, plans to follow suit in next December, leaving just the United States at odds with the issue of reciprocity of visa-free travel with the EU.

The EU says if a visa requirement for Americans is introduced, it would be temporary, according to a story in Money, which did not give a time frame.

The Climb to the Top

    My life as a kid was a sweet life. I lived in a beautiful house with the beautiful surroundings in Puerto Rico. There was one particular thing I loved and it was a huge tree that was in my backyard. As a child, I used to climb the tree every day. Every time I went, I climbed higher and higher, reaching new branches, obstacles, and pathways on my way up. One day, I reached the top and I could see my island. I felt I was on top of the world, and nothing could stop me. Then, there was the day that seemed like the end of my life. This specific day changed my life forever.

It was a nice summer day. After breakfast, my family headed to the park to see my baseball game. In the evening we went to a carnival (嘉年华) in my town. My grandma was selling blankets under a tent. Suddenly, the mood of the day changed when my parents took me to my grandma's tent. Still to this day, I remember the exact words my dad said to me, "Son, how would you like to move to the United States?" I couldn't believe what he said. I then ran away from him as the tears rolled down my cheeks. My perfect life was being taken away from me.

    Two weeks later, we arrived at New York in late July, and my aunt and uncle drove us to Springfield，Massachusetts where we lived for seven years. Once we got there, I met my mom's family for the first time. September came and school started. I was afraid to go to a new school and make new friends. Most kids ignored me and some tried to talk to me, but I couldn't understand them or say anything. My first year in the United States was not fun or easy but I worked hard and got through it.

    Now that I'm grown, I look back on the journey that I've been through: living in a new place with no friends, new language, and new schools. Despite all those problems, I still remembered that special tree. That tree taught me to never give up and reach higher. I have beaten every difficulty that I have met in life and I just kept moving forward. My perfect life was never taken away from me; it has just started.

    The popular image of the mountain climber is of a person carefully climbing a steep cliff with a network of safety ropes, but it is not the only kind. Many climbers now enjoy bouldering. It's more accessible and better for the environment.

    Here is an example of a climber addressing a bouldering problem.

    Figure 1: The climber has two routes she could take, one to the left and one to the right. The left one appears easier because it has a jug within easy reach, but look what happens if she chooses that direction. She gets stuck on the rock and has to go back down. Sometimes that is even more difficult than going up.

    Figure 2: The climber takes the one to the right this time. Using a foothold and placing her right hand in a crimp, she is able to lift herself up and locate other handholds. After only a few moves, she is able to throw her leg over the top of the boulder and pull herself up.

    I was in the seventh grade, and we had moved to New Jersey in November. By then, everyone already had had their own friends, and no one wanted to talk to a new girl. To make things worse, they put me in "Section L". I found out later that everyone called Section L "Loserville". It was sort of an open secret that it was the section for troublemakers and not-so-smart kids. When I found out, I wanted to scream. I had always been a good student and had amazing friends, and now everyone thought I was a loser!

    I did text my friends in Illinois almost every night, especially my best friend, Ana. At first my friends wanted to hear all about it. But then some stopped texting back once I said something about how miserable I was. One night when I was texting with Ana, I complained about another friend who had just done that.

    Ana's texts came really fast for the next few minutes and they surprised me. She said that she was tired of hearing about how bad everything was in New Jersey, too. She said she did not want to hurt my feelings but that I needed to stop feeling so sorry for myself all the time, I had to try to make things better.

    The next day, I thought a lot about what Ana had said. She was right!

    I wish I could say that everything changed overnight after that, but it didn't. I was still stuck in "Loserville", and some people were still mean to me, even though I tried to just stay out of their way.

    But what did change was me—I stopped feeling so sorry for myself and did something about making friends. I signed up to make sets for the school play. I met a lot of new people there, and suddenly I had friends to say hi to in the halls!

    I still miss Illinois sometimes  but life in New Jersey isn't so hard anymore. Even though I couldn't change my situation, I could change my attitude—and that made all the difference.
