Orville Wright was born on August 19, 1871 in Dayton, Ohio, USA and died on January 30, 1948. Together with his brother, Wilbur, he was the first airplane builder. The brothers created the first controlled, powered and heavier-than-air human flight.

    His parents were Milton Wright and Susan Catherine Koerner and besides the two famous brothers they had five children. One day after a trip his father brought as a gift a small helicopter. The kids loved it and as they played daily with it after a while it broke. The brothers managed to create a new one. Wright even let go his plans of attending Yale. He spent his time helping his ill mother and reading in his father's library.

    In 1884 the family decided to move to Dayton and they remained there until the 1870's. A printing press was built by the two and Wilbur was an editor. In 1892 they started being fascinated by the aeronautical （航空的） events of that time. Then they started to create an airplane and Wilbur was considered the head of the team. They were the inventors of “three axis-control”, which permitted the pilot to steer the aircraft's balance.

    In 1900 they had their first attempts to make a functional glider（滑翔机）— of course it didn't have a pilot. After three years they thought of introducing an engine to the glider. At first, their patent(专利) application was refused in 1903, but after one year it was accepted.

    Orville's first flight lasted 12 seconds and had 36.5 meters. He was responsible with the public shows near Washington in the United States. On September 9, 1908 his flight was 62 minutes and 15 seconds long and the success was huge.

Guide to Stockholm University Library

    Our library offers different types of studying places and provides a good studying environment.

Zones

    The library is divided into different zones. The upper floor is a quiet zone with over a thousand places for silent reading, and places where you can sit and work with your own computer. The reading places consist mostly of tables and chairs. The ground floor is the zone where you can talk. Here you can find sofas and armchairs for group work.

Computers

    You can use your own computer to connect to the wi-fi specially prepared for notebook computers; your can also use library computers, which contain the most commonly used applications, such as Microsoft Office. They are situated in the area known as the Experimental Field on the ground floor.

Group-study places

    If you want to discuss freely without disturbing others, you can book a study room or sit at a table on the ground floor. Some study rooms are for 2-3 people and others can hold up to 6-8 people. All rooms are marked on the library maps.

    There are 40 group-study rooms that must be booked via the website. To book, you need an active University account and a valid University card. You can use a room three hours per day, nine hours at most per week.

Storage of Study Material

    The library has lockers for students to store course literature. When you have obtained at least 40 credits(学分), you may rent a locker and pay 400 SEK for a year's rental period.

Rules to be Followed

    Mobile phone conversations are not permitted anywhere in the library. Keep your phone on silent as if you were in a lecture and exit the library if you need to receive calls.

    Please note that food and fruit are forbidden in the library, but you are allowed to have drinks and sweets with you.

    My husband and I had been married nearly twenty-two years when I acquired Stevens-Johnson syndrome,a disorder where my immune system responded to a virus by producing painful blisters（水疱）.Although my long-term evaluation was good,I,who had been so fiercely independent,rapidly became absolutely helpless.

    My husband,Scott,stepped up to the plate,taking care of kids and cooking dinners.He also became my personal caretaker,applying the medicine to all of my blisters because my hands couldn't do the job.Needless to say,I had negative emotions,bouncing from embarrassment to shame caused by total reliance on someone other than myself.

    At one point when I had mentally and physically hit bottoms I remember thinking that Scott must somehow love me more than I could ever love him.With my illness he had become the stronger one,and I the weaker one.And this disturbed me.

    I recovered from my illness,but I couldn't seem to recover from the thought that I loved my husband less than he loved me.This seeming distinction in our love continued to annoy me for the year following my illness.

    Then recently Scott and I went on a long bike ride.He's an experienced cyclist;I'm quite the green hand.At one point with a strong headwind and sharp pain building in my tired legs,I really thought I couldn't go any further. Seeing me struggle,Scott pulled in front of me and yelled over his shoulder,"Stay close behind me."As I fell into the draft of his six-foot-three-inch frame and followed his steps,I discovered that my legs quit burning and I was able to catch my breath.My husband was pulling me along again.At this very moment I woke up to what I now believe: during these and other tough times,love has the opportunity to become stronger when one partner learns to lean on the other.

    I pray my husband will always be strong and healthy.But if he should ever become the struggling one,whether on a bike ride or with an illness,I trust I'll be ready to call out to him: Stay close behind me—my turn to pull you along.

    For thousands of years, we have looked for ways to measure time. Early humans found that the regular movements of the sun, the earth> the moon, and the stars made good ways to measure time. The rising and setting of the sun were used to distinguish (辨别) day from night.

    But, eventually, people needed to tell time more accurately, or exactly. So, by using the sun's position in the sky, they divided the day into dawn, morning, midday and evening.

    Then it was noted that the sun cast a changing shadow as it moved across the sky. Time could be told more accurately by setting up a stick and marking the positions of the sun's shadow. It was the ancient Greeks who divided each position of this “sundial (日晷)” into hours.

    But the sun doesn't always shine. So, for the past 6,000 years, many other ways of keeping time have been tried. Slow-burning candles were divided into hours, and the hourglass was invented. When all the sand in the top of an hourglass has shifted to the bottom, an hour has passed.

    Later, the pendulum (摆钟), with its regular back-and-forth movement of weights, was used to move the hands on a clock. Pendulums are still used in grandfather clocks.

    Today, even more accurate clocks are in use, such as battery-operated quartz clocks (石英钟), digital clocks, and clocks run by electrical tuning forks and tiny atoms. These atomic clocks are the most accurate clocks ever invented. The exact time can be kept to within 1 second a century.

    Feelings often run high where insects are concerned, with many people even sick when seeing them, let alone touch or swallow them. And yet insects present a huge nutritional opportunity as an increasing global population seeks more sources of food and feed.

    Insects have generally high levels of animal protein and key micronutrients with lower environmental footprints than traditional alternatives, and they can be raised on leftovers. But cultural, social and economic problems remain, reports an article published today in Nutrition Bulletin.

    “Insects present a nutritional opportunity, but it is unclear how their nutritional quality is influenced by what they are fed,” says Darja Dobermann, a researcher at the University of Nottingham. “In ideal conditions, insects have a smaller environmental impact than most traditional western forms of animal protein; less known is how to raise insect production while maintaining these environmental benefits.”

    “Studies overall show that insects could make valuable economic and nutritional contributions to the food or fed systems, but there are no clear regulations in place to bring insects into such supply systems without them turning into a more expensive version of poultry（家禽）for food,” says Dobermann.

    The article highlights how insects have been a source of food for hundreds of years in more than 100 countries with over 2,000 species that can be eaten; in central Africa, up to 50% of dietary protein has come from insects, with their market value higher than many alternative sources of animal protein.

    Insects need to be large enough to make the effort of catching them worthwhile and easy to locate, preferably in predictably large quantities. They are consumed at various life stages, as raw, fried, boiled, roasted or ground food.

A simple gesture can be formed into a child's memory so quickly that it will cause the child to give a false answer to a question accompanied by that gesture. A new finding suggests that parents, social workers, psychologists and lawyers should be careful with their hands as well as their words. 

Gestures can be as informative as speech, but hand gestures are so common that we rarely notice we're using them. 

While the recall of both adults and children are easy to react to suggestion, the memories of children are known to be particularly influenced, said lead researcher Sara Broaders of Northwestern University. Kids are used to looking to adults to tell events for them and can be misled even if not intentionally(故意地). 

Previous research, for example, has shown that detail-loaded questions often cause false answers; when asked, say "Did you drink juice at the picnic?", the child is likely to say "yes" even if no juice had been available. It is not that the child is consciously lying, but rather the detail is quickly formed into his or her memory. 

To avoid this problem, social workers have long been advised to ask children only open-ended questions, such as "What did you have at the picnic?" But an open-ended question paired with a gesture, briefly meaning a juice box, is treated like a detailed question. That is, children become likely to answer falsely. 

And it isn't just a few kids: 77% of children gave at least one piece of false information when a detail was suggested by an ordinary gesture. Gestures may also become more popular when talking with non-fluent language users, such as little kids, Broaders said as hand movements can impart meaning of unfamiliar words and phrases. "It certainly seems reasonable that adults would gesture more with children. "

In general, Broaders advises parents and other adults to "Try to be aware of your hands when questioning a child about an event. Otherwise, you might be getting answers that don't reflect what actually happened. "
