When the Apollo astronauts (宇航员) landed on the Moon in 1969, millions of people were rather sad. The person to blame for this was an artist named Chesley Bonestell. For many years, Bonestell had been creating beautifully detailed paintings of the Moon and planets. Viewers of his artwork were unhappy because the real Moon did not look like Bonestell's pictures of it.

    As a space artist, Bonestell tried to make his drawings look exciting and as true as the Moon is. He worked closely with astronomers and scientists to get the most up-to-date scientific information available. But in the 1940s and 1950s, no one had ever seen another planet up close. Yet Bonestell's paintings looked so real that some people thought they were photographs.

    Even though Bonestell was interested in astronomy, he did not start out as a space artist. As a young man he studied architecture — the art and science of designing and making buildings. In 1938 Bonestell became a special effects artist in Hollywood. It was here that he learned he could improve his paintings by following the methods used in the movies.

    In 1944, a popular magazine published a series of Bonestell's paintings of the planet Saturn. He drew Saturn as if it were seen by someone standing on each of the planet's moons. The results were dazzling. Within a few years, Bonestell's artwork was appearing regularly in magazines and books on astronomy and space flight.

    Many of Bonestell's artworks had been right all along. But the biggest surprise was the Moon. Someone asked Bonestell what he was thinking when he saw the first pictures from the Moon. “I thought how wrong I was!” he said. “My mountains were sharp (陡峭的), and they aren't on the Moon.”

    But he shouldn't have felt bad. No space artist had ever before taken so many people to so many faraway worlds. In the years just before the first manned space flights, Bonestell's artwork prepared people for the amazing space adventure to come.

    When I graduated from college I dreamed of being a television news reporter. Having no experience, I had to work in a small town until I finally got my big break in the form of a job in Boston. I made it.

    Soon, reality set in. I was too often sent to run after accused criminals out of courts, waiting outside of crime scene tape or at the doorstep of a family still crying for tragedy (悲剧). My breaking point came the day I accidentally informed a young woman that her mother died. It was the worst day of my professional life and the day I decided I no longer wanted to shine a light on these stories. My career was ebbing, and at the same time my personal life was too-I divorced.

    My mom had always told me “When you're feeling extremely upset, go help someone else.” So I started seeking out stories of people who had been in the news under tragic circumstances but were doing something inspiring with their lives: a young girl who was paralyzed (瘫痪的) by an accident but was uplifting her classmates with her positive spirit, a blind and autistic (自闭的) musician who learned to play 27 instruments, a disabled soldier who opened his own art studio. I started to tell and promote stories like them.

    Over the last 10 years I have discovered my kindness gift: my ability to see the beautiful side of a person and reflect it back to them and the world. In telling stories of people turning their own hurt into acts of helping others I have become more sympathetic, more grateful and kinder. I have learned kindness is who we are, that our power for it is limitless and that, as we shine a light on it, it grows.

    Last month I was lucky enough to have a chance to make a trip into space with my friend Li Yanping, an astronomer. We visited the moon in our spaceship!

    Before we left, Li Yanping explained to me that the force of gravity would change three times on our journey and that the first change would be the most powerful. Then we were off. As the rocket rose into the air, we were pushed back into our seats because we were trying to escape the pull of the earth's gravity. It was so hard that we could not say anything to each other. Gradually the weight lessened and I was able to talk to him. "Why is the spaceship not falling back to the earth? On the earth if I fall from a tree I will fall to the ground." I asked. "We are too far from the earth now to feel its pull, " he explained, "so we feel as if there is no gravity at all. When we get closer to the moon, we shall feel its gravity pulling us, but it will not be as strong a pull as the earth's. " I cheered up immediately and floated weightlessly around in our spaceship cabin watching the earth become smaller and the moon larger.

    When we got there, I wanted to explore immediately. "Come on," I said. "If you are right, my mass will be less than on the earth because the moon is smaller and I will be able to move more freely. I might even grow taller if I stay here long enough. I shall certainly weigh less!" I laughed and climbed down the steps from the spaceship. But when I tried to step forward, I found I was carried twice as far as on the earth and fell over. "Oh dear," I cried, "walking does need a bit of practice now that gravity has changed." After a while I got the hang of it and we began to enjoy ourselves.

    TED is a non-profit organization devoted to Ideas Worth Spreading. It started out (in 1984) as a conference bringing together people from three worlds: Technology, Entertainment, and Design. Since then it has stepped into more and more fields. It includes two annual ( 年度的) conferences-the TED Conference on the North American West Coast each spring, and the TED Global Conference in Edinburgh UK each summer, which bring together the world's most excellent thinkers and doers, who are challenged to give the talk of their lives ( in 18 minutes or less).

    On ted.com, we make the best talks and performances from TED and partners available to the world, for free. More than 1, 200 TED talks are now available,' with more added each week, which cover almost all topics from science to business to global issues- in more than 110 languages. They really help share ideas in communities around the world.

    We believe in the power of ideas to change attitudes, lives and eventually, the world. So we' re building here a clearinghouse (信息交流中心 ) that offers free knowledge and inspiration from the world's most inspired thinkers, and also a community of curious souls to engage with ideas and each other. Have an idea? We want to hear from you.

    Today, TED is best thought of as a global community. It's a community welcoming people from every field and culture who seek a deeper understanding of the world.

    Wilbur and Orville Wright were the two youngest sons of Bishop Milton Wright, Wilbur was born on a farm near Millville and Orville was born in August in the house the family would come to occupy for more than 40 years in Dayton.

    Orville would discover in later years that he and Wilbur's first interests in flight began when they were children, with powered rubber-band-helicopter toys that their father would bring home for them from trips around the country. Orville and Wilbur would build duplicates（复制品）of these toys and bounce them off the ceiling. They were just crazy about these things for the reasons that they did not yet understand.

    Both boys loved to solve problems that seemed difficult to others. The more difficult the problem was, the more they saw it as a challenge. Exploring the unknown was such a joy for then that Orville once said, "I can remember when Wilbur and I could hardly wait for the morning to come to get at something that interested us. That's happiness."

    Putting their gift to work, the boys entered the printing business soon after high school. Orville designed and then built a printing press（印刷机）for this enterprise. At first, they did contract printing for other people, and soon one of their customers during the early 1890s was Father Milton's church. They also tried the newspaper business, and although their two newspapers, the West Side News and The Evening Item were considered to be of high quality, Dayton already had daily newspapers, so the Wrights soon returned to contract printing.

    Branching out into other areas, they also opened a bicycle business. Bicycling was the fastest growing sport in the country at that time, and their repair shop soon led them into building bicycles of their own design, often with tools of their own construction, such as the lathe（车床）driven by a one-cylinder gasoline engine built by Orville. The bicycle shop would provide the livelihood（生计）that would allow them to carry out their experiments on airplanes.
