Q: Article: Although Thomas Edison created the technologies behind three major 21st century industries electrical power,recorded music and movies--his greatest invention may have been the modern method of inventing.He basically came up with the modern system of research and development.Edison was not the only scientist doing research in his garage but someone who gathered around him a team of creative scientific minds.Edison's 1aboratories were the forerunners of Apple,Google and Microsoft. Yet for a11 his scientific gifts,he was no Steve Jobs or Bill Gates.He once said,"Anything that won' t sell,I don' t want to invent." But Edison,unlike Jobs or Gates,had no real sense of what the public wanted or how to change his discoveries into products that might sell.It took him years to understand that the phonograph was not a business tool but an entertainment invention.He helped create movies but resisted the idea that people might want to go into a theater to watch one. We chose Edison this year because we need his example now more than ever.Though we live in a time of great reformation,the U.S.is in danger of losing its advantage in science and technology.American investment in research and development has not increased as a percentage of GDP since the mid1980s,while the government' s share has been dropping.And this is at a time when China is rapidly increasing its money on research and development.The U.S.was once among the 1eading nations.Now it ranks near the bottom of the 23 nations that collect such data.We hope that Edison' s story might not only encourage reformation but also inspire more young Americans to study science and engineering.
Answer: Edison wanted to invent things that sold well.

Q: Article: Astronomers say they are on the point of finding planets like Earth orbiting other stars, which is a key step in determining if we are alone in the universe. A top NASA official and other leading scientists say that within four or five years they should discover the first Earth-like planet where life could develop, or may have already. A planet close to the size of Earth could even be found sometime this year. At the annual American Astronomical Society conference this week, each discovery involving so-called "exoplanets" --those outside our solar system -- pointed to the same conclusion:Quiet planets like Earth where life could develop probably are plentiful. NASA's Dew Kepler telescope and a lot of new research from the suddenly hot and competitive exoplanet field caused noticeable buzz at the meeting.Scientists are talking about being at "an incredible special place in history" and closer to answering the question. "Are we alone? For the first time, there's an optimism that sometime in our lifetimes we're going to _ that," said Simon Worden,an astronomer who heads NASA's Ames Research Center. "If I were a betting man, which I am, I would bet we're not alone." "These are big questions that reflect upon the meaning of the human race in the universe," the director of the Vatican Observatory, the Rev. Jose Funes, said Wednesday in an interview at this week's conference. Worden told The Associated Press: "I would certainly expect in the next four or five years we'd have an Earth-sized planet in the habitable zone."

Q: Article: Last year I ruined my summer vacation by bringing along a modern convenience that was too convenient for my own good: the iPad. Instead of looking at nature, I checked my e-mail. Instead of paddling a small boat, I followed my Twitter feed . Instead of reading great novels, I stuck to reading four newspapers each morning. I was behaving as if I were still in the office. My body was on vacation, but my head wasn't. So this year I made up my mind to try something different: withdrawal from the Internet. I knew it wouldn't be easy, since I'm bad at self-control. But I was determined. I started by giving the iPad to my wife. The cellphone signal at our house was worse than in the past, making my attempts at cheating an experience in frustration . I was trapped, forced to go through with my plan. Largely cut off from e-mail, Twitter and my favorite newspaper websites, I had few ways to connect to the world except for the radio--and how much radio can one listen to, really? I had to do what I had planned to do all along: read books. This experience has had a happy ending. With determination and the strong support of my wife, I won in my vacation straggle against the Internet, realizing finally that it was I, not the iPad, that was the problem. I knew I had won when we passed a Starbucks and my wife asked if I wanted to stop to use the Wi-Fi. "I don't need it," I said. However, as we return to post-vacation life, a harder test begins: Can I continue when I'm back at work? There are times when the need to know what's being said right now is great. I have no intention of giving up my convenience completely. But I hope to resist the temptation to check my e-mail every five minutes, which leads to checking my Twitter feed and a website ortwo. I think a vacation is supposed to help you reset your brain to become more productive. Here I hope this one worked.
