While dog keepers realize their dogs can read their moods accurately, scientists have always been a little doubtful. Now thanks to some researchers at the University of Veterinary Medicine in Vienna, Austria, we finally have some convincing evidence.

    For their study, biologist Corson Miller and his team exposed eleven selected dogs to digital images of women that were either angry or happy. Half the dogs were rewarded for touching the screen when shown a happy face, while the other half got their treat for selecting those that appeared angry.

    Interestingly, the dogs were not provided with the entire face. Some dogs were shown only upper halves while the others observed lower halves. That's because the scientists believe humans show their emotions on their entire face.

    After some training like how to recognize small differences like the wrinkles between the eyes or the changes in their shape that accompany the happy or angry expressions, the dogs were mostly able to identify the correct expression not only on a familiar face but on a strange face. The researchers concluded the dogs were smart enough to read human emotions.

    They also found those being trained to read angry expressions took a longer time to learn. They guess it may be because dogs find angry faces disgusting, causing them to withdraw quickly. However, once the smart dogs realized they were getting rewarded, the trepidation seemed to disappear. In fact, the dogs had such a good time playing the computer "game" that scientists had a hard time keeping them away from the touch screens after the study was completed.

    The researchers also noticed only dogs with a male owner had a harder time understanding the expressions correctly. Since the touchscreen models were all females, this confirmed what has been observed in previous studies—dogs are more efficient at reading facial expressions of people that are the same gender as their owner.

    Two men were sitting together in a plane. They were on a long journey. One of the men was a businessman. The other was a farmer. They sat without talking for a while, then the farmer said, “Let's do something to pass the time.”

     “What do you want to do?” the businessman asked. “We can ask each other riddles.” The farmer said, “You start.” “Let's make the rules first,” the businessman said. “That's not fair. You are a businessman with much knowledge. You know more things than I do. I am just a farmer.”

    “That's true.” The businessman said. “What do you want we should do?” “If you don't know the answer to a riddle, you pay me $100. And if I don't know the answer, I'll pay you $50.” The farmer said. The businessman thought about this, then he said, “OK. That's fair. Who will go first?”

    “I will,” The farmer said. “Here is my riddle. What has three legs when it walks, but only two legs when it flies?” The business man repeated the riddle, “What has three legs when it walks, but only two legs when it flies? Mm, that's a good one. I'm afraid I don't know the answer.” He gave the farmer $100, then said, “Tell me the answer. What has three legs when it walks, but only two legs when it flies?” “I don't know.” The farmer said and gave him $50.

    I recently had dinner with someone who told me that one of his best friends had been killed in a private plane crash, and something happened at the memorial service that he'll never forget. He shared the story with me.

    At the memorial service, his friend's wife walked to the platform to speak to the gathering. She said a friend had asked her the best memory she had of their life together. At the moment, she had been too sad to answer, but she had thought about it since and wanted to answer the question.

    They were in their late forties when he died, and she began talking about a time in their life almost twenty years earlier. She had quit her job to obtain her master's degree, and her husband never hesitated in his support.

    He held down his own job and also did the cooking, cleaning, and other housework while she studied for her degree.

    One time they both stayed up all night. She was finishing her paper, and he was preparing for an important business meeting. That morning, she walked out of her study, leaned against the door by the stairs, looked at her husband downstairs and just thought about how much she loved him. She knew how important this meeting was to his future, and she was feeling guilty that she didn't even have time to make his breakfast. He took his briefcase and hurried out. She heard the garage door open and close, but much to her surprise, she heard it open again about thirty seconds later. From above, she watched her husband dash into the house and walk over to the forgotten coffee table. Marking the surface of it with his finger through the dust with the words "I love you", then he raced back to his car.

    The new widow then looked out at her audience and said, "John and I had a wonderful life together. We have been around the world several times. We've had everything money can buy but nothing comes close to that moment."

    Hearing this, I was deeply moved. "Love makes life worthwhile."

    One time a young man, who hoped to study law, wrote to Lincoln for advice, and Lincoln replied, "If you are determined to make a lawyer of yourself, the thing is more than half done already. Always bear in mind that your own determination to succeed is more important than any other one thing."

    Lincoln knew. He had gone through it all. He had never, in his entire life, had more than a total of one year's schooling. And books？Lincoln once said he had walked to borrow every book with in fifty miles of his home. A fire was usually kept going all night in the small house and he read by the light of it.

    He walked twenty or thirty miles to hear a speaker and, returning home, he practiced his talks everywhere﹣in the fields, in the woods, before the crowds. He joined several societies and practiced speaking on the topics of the day.

    A lack of confidence always troubled him. In the presence of women he was shy and dumb. Even when he was in love with Mary Todd, he used to sit there, nervous and silent, unable to find words, listening while she did the talking. Yet that was the man who, by practice and home study, made himself into the speaker who debated with the famous speaker Douglas! That was the man who, in Gettysburg address, rose to the heights of eloquence （雄辩） that have seldom been achieved in all the human history.

    Small wonder that, speaking of his own great barriers and painful struggle, he wrote, "If you are determined to make a lawyer of yourself, the thing is more than half done already."

    Here are some great people and their achievements.

    Mary Anderson ­ windscreen wiper.

    Back on a freezing winter's day in 1902, Mary Anderson was travelling by train through New York City. Snow was falling, forcing the driver to stop repeatedly and get out to clear it. Each time the door opened, Mary suffered a gust of sub-zero air. She had an idea: why not make some kind of a rubber blade that could be operated from inside the vehicle? And that's exactly what she did.

    Josephine Cochrane ­ dishwasher

    The dishwasher dates back even earlier to the 19th century, and to the dinner parties thrown by a lady called Josephine Cochrane. As a frequent host, she wanted a machine that could wash dishes faster than people. Her response was to develop what was to become the first commercially successful dishwasher. Interestingly, innovation was in her blood: her grandfather had invented the steamboat.

    Stephanie Kwolek ­ Kevlar

    Kevlar is the lightweight fibre used in bulletproof vests. The material is used by millions every day and has saved countless lives. The super tough fabric is also used in objects ranging from gloves to airplanes. Incredibly, its strength-to-weight ratio(比强度) is five times higher than steel. Again, it was invented by a woman, the American chemist Stephanie Kwolek, in 1964.

    Grace Hopper ­ first compiler(编译程序)

    One of the most important inventions of the 20th century must surely be the computer programme. The world of programming is unbalanced in terms of gender. Men vastly outnumber women, and take home around 30% more pay than their female counterparts on average. But back in the 1940s and 1950s, women were at the forefront of this new field. Grace Hopper is credited with inventing the first compiler in 1952, which serves as the bridge between code and the binary(二进制的) ones and zeros understood by computers.
