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.

    Stocky, slow-moving whale, rarely grows beyond 15 metres in length

    Flippers are a third of body length; variable dorsal fin size and shape; saw-toothed trailing edge on flukes, often raised when diving

    Bumpy tubercles on top of head

    Body colour is dark brown to black; often extensive white on flippers and underside of body and flukes; such patterns enable individual recognition

    Bushy blow, occasionally V-shaped

    270-400 olive baleen plates

    Humpback whales belong to the rorqual (groove-throated) family, which includes fin, sei, Bryde's, minke and blue whales. The big family migrate between winter tropical breeding areas (North West Shelf, Great Barrier Reef, New Caledonia, Vanuatu, Fiii, Tonga) and summer Antarctic feeding areas. Once common in New Zealand waters, humpbacks are now rarely seen and may migrate further offshore. Males compete for mates either by physical fight or by song. Females give birth to their young every two to three years; some non-breeding females probably remain in the southern waters during winter. Young humpback whales return to their area of birth but in later life some wander between breeding areas. Humpbacks eat small shrimps and other schooling prey, such as fish, forming small, cooperative groups of two to three individuals to feed.

    Similar species: Easily identifiable due to a 'hump' back when submerging, but at a distance may be confused with other species that raise their flukes when diving, such as sperm, right and blue whales.

    Protection status: Recovering well from past whaling and now numerous in some former migration and aggregation areas, rarely seen in others.

    Around the world, 62 million girls are not in school. The White House's Let Girls Learn effort aims to change that.

    At 13, Hawa Abdulai Yorke left her family's home, in Ghana, Africa, to live with an aunt who promised to send her to school. Instead, the aunt put Yorke to work as her maid. Determined to go to school, Yorke returned home and began selling water in a nearby city to raise
money for her education. She did that for three years. What hurt most was that her father had the money to pay the school fees. But he chose to spend the money on a motorcycle.

    Yorke's story is familiar to girls growing up in Ghana. There, a girl's place is in the home. Educating girls is considered a waste of money.

    “It happens more than it should, where parents have money to send their girls to school but choose not to,” says Ryan Roach, a Peace Corps volunteer in Ghana, where nearly 55% of girls are not enrolled in secondary school. “Cultural beliefs say education is not a wise investment(投资)”

    The White House's Let Girls Learn is working to change this view of girls' education, in Ghana and in countries worldwide. First Lady Michelle Obama says parents have to be persuaded that girls' education is a better investment than marriage or household labor. A World Bank study backs that up. It shows that for every year of secondary-school education, a girl's earning power increases by 18%.

    Today, Let Girls Learn works in 13 countries, and there are plans to expand the program. Recently, Let Girls Learn hosted a 24-hour event at which girls in different parts of Ghana joined Peace Corps volunteers, tech experts, and university students to brainstorm creative solutions for the barriers to girls' education. Yorke's team came up with an idea for an app that sends a recorded message to parents' phones from a Ghanian celebrity about the benefits of girls 
attending school.

    Yorke, now 22, is about to finish high school. Thanks to Let Girls Learn, she plans to attend college and study computer science. She says working alongside women college students at the Let Girls Learn event strengthened her determination. “I'm focused on my books,” says Yorke. "I know if I study hard, I, too, can go to the university and live a happy life."

    During my stay in Mumbai, I often went to Pune. Though the two cities are only about 145 km away from each other, traveling that distance is a headache. But work required me to do it and I would have to travel at least twice a week at some point.

    This time I was traveling around October. We started from Pune at around 5 p.m. Like all the drivers, this taxi driver also struck up a general conversation about me and my city. He started by saying that kids are one's greatest happiness. As a bachelor(光棍汉), I got a little angry when he started all about kids and family. Then he said something that really attracted me. He said he was a musician. I asked him which instruments he played, he replied,"I have an electronic system". Thinking that taxi drivers tend to be unable to buy an electronic system, I doubtfully listened to him continuing with his story.

    His name was Naveen. He was basically a musician who was expert in playing guitar and the keyboards. Naveen had left his family after a quarrel with his father over taking music as a career. Naveen had his instruments but didn't know how to earn money. The only other thing he could do was to drive. So he joined Mumbai-to-Pune taxi services. That served him as the regular income in weekdays and in the weekends he'd perform in Pune, Nasik or Mumbai. By now, he'd become a slightly famous musician in Maharashtra. But he had a condition wherever he played. He asked that the place couldn't be ticketed. They can charge for food or drinks if it's a pub or a restaurant but no tickets.

    I heard Naveen's songs. He was amazing. He had a trick which made me call him a genius(天才). Among all the faceless drivers, Naveen stood out. He inspired me to leave my job and start a theatre career in Delhi.

    Forty-three years ago, a man took a "small step" on the moon and brought mankind a "giant leap" forward. As the first person to walk on the moon, American astronaut Neil Armstrong is a man whose name will be remembered for generations to come.

    But being the first is never easy. With so many unknowns about space at that time, Armstrong himself was astonished that Apollo 11 actually worked. He thought he and his partners had merely a 50 percent chance of a successful landing back in 1969.

    It was tough indeed. When the module (登月舱) was approaching the moon's surface, the computer wanted to rest them on a steep slope covered with rocks, but Armstrong realized it was an unsafe place to stop.

    As a last minute decision, he safely landed the module by himself. When they finally touched the ground, "there was something like 20 seconds of fuel left," he said in an interview earlier this year.

    Unfortunately, some people doubted his visit to the moon, saying it was faked. But Armstrong responded with a chuckle (轻声笑), saying: "It was never a concern to me because I knew one day, somebody was going to go fly back up there and pick up that camera I left."

    For all his global fame, Neil Armstrong is a remarkably modest man. He rarely gave interviews and didn't like talking about his achievement. He stopped giving his signatures when he found that people sold them for thousands of dollars.

    "I guess we all like to be recognized not for one piece of fireworks but for the ledger (记账簿) of our daily work," Armstrong said in a CBS interview in 2005. When asked how he felt knowing his footprints would be likely to stay on the moon's surface for thousands of years, he said: "I kind of hope that somebody goes up there one of these days and cleans them up."

    Armstrong passed away last month at the age of 82, but he will be memorized. "The next time you walk outside on a clear night and see the moon smiling down at you, think of Neil Armstrong and give him a wink (眨眼示意)," his family said to Reuters.

    Wong Fuk-wing, a Hong Kong volunteer at an orphanage (孤儿院) in Yushu, was killed in the earthquake when he was trying to save others on April 14, 2010.

    Wong managed to run safely out of the building with some children when the first quake happened at 7:50 am on April 14, but he went back inside to rescue three other children and three teachers inside, although he knew the danger of aftershocks (余震).

    At 10 am, all the children and one of the teachers were saved. However, Wong was buried under the fallen building and died. The other two teachers were still waiting to be rescued.

    46-year-old Wong was a truck driver, who often said he could only give his efforts to charity instead of money, as he did not earn a lot. His tragic (悲剧的) end touched the hearts of many people both in Hong Kong and on the mainland.

    Wong began volunteering in 2002. In 2003, Wong was told by the doctor he got serious illness, which gave him a great blow. However, the illness did not deter the warm-hearted man. When the earthquake struck Wenchuan in Sichuan Province in 2008, Wong rushed to the disaster area of Shifang to offer his help though his family did not want him to go.

    In fact, Qinghai is a place Wong had often visited since 2006. As a volunteer, he gave out medicine and clothing to the orphanage there. No one could expect that Wong would die helping others.

    Hong Kong Chief Secretary Henry Tang Ying-yen said he had "the highest respect" for the hero who gave his life for others. "What he did has shown the Hong Kong spirit." The citizens of Hong Kong called him "the pride of Hong Kong's people" and people on the mainland have also praised him as "a true hero".
