Balloon Volleyball

    It's a rainy, dark day and there's nothing to do. You don't feel like sitting quietly but you are not allowed to make a lot of noise. What can you do for fun? Try balloon volleyball.

    Items needed for this game: a balloon (or two, in case the first one bursts), some ropes, two chairs, at least two people and a room.

    Set up the room. If you're in the living room, or a family room, be sure to move all the furniture out of the way. Get two chairs and set them in the middle, outer edges(边缘)of the room. They should be at the same place where you put a volleyball net. Turn them so that the seat is facing the wall, not the “playing” space. Tie the rope onto the top of the chair, and run the rest of the rope to the other chair. Now tie it on this chair at the same place as the first chair. You can decide the “out-of-bounds”(出界) lines, if you want to have them, but they really are not necessary in this game.

    Blow up the balloon. Choose sides. You will play this game on your knees (at least until they start hurting and you want to stand). Each side must get the balloon over the rope in three hits. If it does not get over, the other side gets the balloon and a point. This game becomes more difficult because you must play without talking.

    You can also add other rules to make it more difficult; for example, you can only use your left hand or only your right hand to hit the balloon.

    Continue playing until one side gets 10 points. You can make your game longer or shorter by changing the number of points it takes to win.

    This is a fun way to get your energy out, have fun, and not make too much noise on a rainy, stay-in-the-house day.

    Colorado officials will stick to a plan to kill some mountain lions and bears to support the state's dropping mule deer (长耳鹿) population.

    Wednesday's vote permits organizations to kill up to 25 black bears and 15 mountain lions per year in the central and western parts of the state. The project will run for three years, to be followed by a six-year study of how deer populations respond to fewer predators(捕食者).

    The population of Colorado's mule deer has suffered a puzzling, years-long drop to about 450,000, which state officials said was about 110,000 fewer than there should be. A 2014 state study tied it to seven causes, including predators, whose number has greatly increased in recent years.

    Some experts, however, said the state should focus first on the human-led destruction(破坏) of mule deer habitat(栖息地). “The drop of the mule deer population is obviously not a simple problem with simple causes,” Brian Kurzel, director of the National Wildlife Federation, said. “By far, the greatest problem—the one that I think deserves the most attention in any science-based study—is habitat quantity and quality.”

    Kurzel pointed out that the U.S Bureau of Land Management recently agreed to create 15,000 new oil and gas wells somewhere in western Cororado, which was often called “the mule-deer factory”. There, the number of mule deer has fallen to about 30,000 from more than 100,000 in the early 1980s. Though state officials have known oil and gas development affects the population of mule deer, they didn't go against the plan.

    Other causes like building highways, population growth and human activities are also curbing the mule deer population, according to the study.

    State Parks and Wildlife officials don't necessarily disagree. They started a $4.5 million program as a way to gather research for later decisions.

    At the end of August this year I moved from London, UK, to a small town in Quebec, Canada, called Matane to work as an English language assistant. Patience is a word that has appeared in many forms over the past two months.

    I don't see myself as being the most patient person in the world but there was something that struck me on my first week of work. I had just finished a session with two students and just as they were leaving the classroom, one of the students turned back and said, "Thank you for your patience." That was an early reminder of the importance of being patient as a teacher. It also made me reflect on the language teachers that I have had over the years, ones that demonstrated a high level of patience and understanding that has shaped my language learning path. Moreover, it helped me to realize the importance of demonstrating patience in the classroom as it can be the difference between building someone's confidence in a language or breaking down their confidence entirely.

    Living my life constantly in French is not easy but the people of Quebec are very patient. They repeat things several times and they are more than happy to wait while I find the correct words to express myself and find the correct word order. It's a learning process but with the patience of others, the process is slightly less nervous. At the end of the day, making mistakes shows you are trying and I think that is greatly appreciated by Quebecers.

    When I first arrived in Matane I kept getting headaches from having to concentrate all the time due to the language and even overhearing other people's conversations was hard work! I had to keep reminding myself that it would take time, and two months later the headaches are a distant memory and my ears have become more tuned to their accent. The key is to be patient with yourself.

    Here are some of the strangest aviation(航空)ideas in recent history.

    Double-Decker Seating

    In 2015, Airbus filed a patent for a design for a double-decker cabin seating arrangement. Passengers would sit on top of the other, with upper-tier passengers climbing steps or a small ladder to reach their seats. While the design does have some advantages, the idea of climbing a ladder during flight seems unreliable.

    Separated Cabins

    This patent was awarded to Airbus. Rather than waiting for a flight to arrive and be cleaned,passengers could simply board a ready cabin, which would be moved into the plane's body as soon as it was ready. When the plane reached its destination, the cabin would be separated again. Different cabins with different kinds of seating or levels of comfort could be used for flights of different lengths or destinations.

    Windowless Cockpits(驾驶舱)

    For ideal design, airplane noses should be long and pointy. But there's the whole "pilots have to fit in the cockpit" problem. Well, what if the cockpit didn't have to go in the nose of the plane? That's part of the thinking behind this Airbus patent application* which suggests replacing the plane's window with a digital viewing surface. Without a window, there's no reason the cockpit needs to go in the front of the plane —it could go in the middle of the plane, or even in the tail.

    Nap Straps (睡眠吊带)

    Airbus is not the only company in the strange patent contest. Boeing's got its own patent, Nap Straps. With this invention, passengers looking for a nap can find an "upright sleep system^" beneath their seat. In action, the whole thing is somewhat like a traction device for someone who's been in a terrible accident.

    Dr. Nancy Roman, born in 1925, who was celebrated as a pioneer for female scientists and had advanced the launch of the Hubble Space Telescope, died on Dec 25, 2018.

    When Nancy Roman asked for permission to take a second algebra (代数)course in high school,a teacher demanded to know "what lady would take mathematics instead of Latin". In college, a professor admitted that he often tried to prevent women from majoring in physics but Nancy stuck to it. And after receiving Doctor's degree in astronomy. , she found a professional home at NASA(美国宇航局)In 1959, Dr. Roman became the first chief of astronomy at NASA. headquarters, a role that made her one of the agency's first female leaders.

    Dr Roman spent much of her career helping develop, fund and promote technology that would help scientists see more clearly beyond Earths atmosphere. But her most well-known work was perhaps leading to design the Hubble Space Telescope the first major telescope to be sent into space for the purpose of gathering photographs and data from the universe. She was, therefore, named as "the mother of Hubble".

    "She made it possible to get the early telescope up into space to learn what needed to be learned," said science historian Bob Zimmerman: and her hard-nosed nature helped get the telescope built.

    The telescope did not launch until 1990, a little more than a decade after Dr Roman retired, but when it did, its photographs of the universe thrilled the world.  I am glad, "she once told Science, "I ignored the people who told me that I could not be an astronomer. "
