Question: Article: You may think that inventions are far away from your everyday life. But in fact, almost everyone can invent. It's just that they do not recognize that their idea could be the start of an invention. Once inventors see their ideas have some practical value, they don't let them slip away. For example, the inventor of the dishwasher, American Josephine Cochrane, loved to give dinner parties. But she found it took too long to wash her dishes by hand and too many of them broke. She decided that a machine could do the job faster and with fewer mistakes. So, in 1886, she set out to make one for herself. Like Cochrane's, most inventions are created to solve a problem. So, the first and most important step is to find the problem. You can start by looking at what is wrong with things you use now. You can ask grandparents or neighbours if they remember ever saying: "I wish someone would invent something for..." Or you can look at people in different areas such as on the street, or at school. Then you might notice situations or things in need of improvement. Remember to record your ideas and work. This will help you develop your invention and protect it when it is completed. The next step is to think about possible solutions. An invention is a new way of solving a problem. So think of many, varied, and unusual ways. You can often come up with a solution for a problem by looking at it from a different angle or thinking about it in a new way. Example 1 -- instead of thinking of shoes as protecting your feet from the ground, think of using something to protect the ground from your feet. Example 2 -- instead of thinking about how you can carry oranges home from a store, think of how they can come to you by delivery or growing your own. Example 3 -- instead of experimenting with only one solution, can you put two or three solutions together, or arrange them in different orders? And if one solution doesn't work, can it be put to other uses? That was how yellow post-it notes (N) came about -- a "failed" adhesive experiment proved a weak adhesive had good uses too! After all, most inventions are not brand new. They do not come out of nowhere, but come out of things or ideas that already exist. And the hardest part of inventing, even for a lot of inventors, is coming up with a problem and finding a solution. Once you have an idea, you can always get help building your invention. This problem-solving technique can also work in your everyday lives. So, why not try it in your studies, in your relationship with others, or even in the way you look at the world?

Question: Article: When a tornado hit the small town of Otwell, Indiana years ago, Kathryn Martin, 32, who lived 60 miles away in Evansville, couldn't get the news out of her mind. "I kept thinking, 'Those poor people. Somebody's got to help them,'" she says. She knew firsthand what they were going through. Six months earlier, a tornado had struck her town, taking the lives of her 2-year-old son, C.J. and her mother-in-law. "It was the most terrible experience of my life," she says. "That _ will never go away, and it broke my heart to think about what these families were going through in Otwell." So Kathryn loaded her car with juice boxes, snacks and toys and drove to Otwell. She gave the items to the Red Cross, and as she was leaving, she saw a couple sorting through the ruins of their home while their children were watching. So Kathryn stopped and gave a few toys to the kids and played with them for a while. "The parents couldn't thank me enough for what I did for their children," she says. On the drive back to Evansville, Kathryn came up with an idea to help more kids. She talked her family, friends and neighbors into joining her and spent the next few months organizing fundraisers. Finally, in August 2007, she showed C.J.'s Bus, a 35-foot school bus that was turned into a mobile playroom. In the following years, stocked with video games and DVDs, toys, crafts, books and more, the bus traveled to disaster-torn towns, giving the children there a safe place to play. So far, C.J.'s bus has traveled to three states affected by tornadoes or floods, cheering up more than 756 children, aged 3-13.

Question: Article: Even before historian Joseph Ellis became a best-selling author, he was famous for his vivid lectures. In his popular courses at Mount Holyoke College in Massachusetts, he would often make classroom discussion lively by describing his own fighting experience in Vietnam. But as Ellis's reputation grew--his books on the Founding Fathers won both the National Book Award and the Pulitzer Prize ---the history professor began to entertain local and national reporters with his memories of war. Last year, after The Boston Globe reported Ellis's experience in the Vietnam war, someone who knew the truth about Ellis _ Last week The Boston Globe revealed that Ellis, famous for explaining the nation's history, had some explaining to do about his own past. "Even in the best of lives, mistakes are made," said Ellis. It turned out that while the historian had served in the Army, he'd spent his war years not in the jungles of Southeast Asia , but teaching history at West Point ( ). He'd also overstated his role in the antiwar movement and even his high-school athletic records. His admission shocked colleagues, fellow historians and students who wondered why someone so successful would beautify his past. But it seems that success and truthfulness don't always go hand in hand. Even among the successful achievers, security experts say, one in ten is deceiving. And, oddly, people often beautify their past once they're famous, says Ernest Brod of Kroll Associates, which has conducted thousands of background checks. Then what makes them do it? Psychologists say some people succeed, at least in part, because they are uniquely adjusted to the expectations of others. And no matter how well-known, those people can be haunted ( ) by a sense of their own shortcomings. "From outside, these people look anything but fragile," says Dennis Shulman, a psychoanalyst. "But inside, they feel hollow, empty,"
