     Stephen Hawking is perhaps the world's most famous living physicist. To the public, he's best known as an author of bestsellers such as The Universe in a Nutshell and A Brief History of Time, which have brought an appreciation of theoretical (理论上的)  physics to millions. He is regarded as having one of the brightest minds on the planet. But outstanding astrophysicist (天体物理学家) Stephen Hawking has admitted that he did not learn to read until he was eight years old.

    In a public lecture at the Royal Albert Hall, Professor Hawking also admitted that he was not active in studying while at Oxford University, where he studied physics, and that only the news that he might die young from motor neurone (运动神经元) disease made him focus on his work.

    Professor Hawking said, “My sister Philippa could read by the age of 4 but then she was brighter than me.” He said that he was common at school and was never further than halfway up his class. “My classwork was very untidy, and my handwriting was very bad in the teachers' eyes,” he said. “But my classmates gave me the name Einstein, so probably they saw signs of something better.”

    But he said that it was when doctors told him that he probably only had a few years to live at the age of 21 that he began to focus on his work, which resulted in some of his early achievements. He said, “When you are faced with the possibility of an early death, it makes you realize that life is worth living and there are lots of things you want to do.” Hawking serves as Lucasian Professor of Mathematics at the University of Cambridge, where he continues to contribute to both high-level physics and the popular understanding of our universe.

    Nikola Tesla

    Long overshadowed in public memory by his one-time employer, Thomas Edison, Tesla (1856—1943) was a brilliant scientist and engineer who earned more than 700 patents. He is most famous for developing alternating current (交流电), but his work also led to advances in wireless communications, lasers, X-rays, radar, lighting, robotics, and much more.

    Tesla was born to Serbian parents in what is now Croatia, but he emigrated(移民) to the U.S. as a young man, where he eventually became a naturalized citizen. Besides Edison, who later became his bitter rival, Tesla often worked with inventor George Westinghouse. In 1893, the pair demonstrated their advances in lighting and motors in the "White City" at the Chicago World's Fair. In 1895, Tesla and Westinghouse developed the world's first hydroelectric power plant, at Niagara Falls.

    At the turn of the century, Tesla set up a laboratory called Wardenclyffe in the small community of Shoreham, Long Island, where he conducted some of his most ambitious experiments. The building was financed by J. P. Morgan and designed by acclaimed architect Stanford White.

    The most prominent feature was Wardenclyffe Tower, also called Tesla Tower, a 187-foot-tall metal lattice tower topped with a big antenna that was intended to beam communications and even energy across the Atlantic.Tesla ran out of money while building the tower and was foreclosed(取消赎回权) on twice. As with his previous Colorado Springs lab, assets were sold to pay up his debts. In 1917, the U.S. government blew up the tower, fearing that German spies were using it in World War I. The metal was sold for scrap. For decades, the building was used for photo processing.

    "The tower is long gone, but the three-quarter-length statue of Tesla unveiled last week is a fitting memorial," said Alcorn, a retired teacher. "This is the last remaining Tesla laboratory anywhere in the world," she said. "He inspires those who work hard but don't get recognition, and people are starting to recognize how important his contributions are."

    As a sign of that growing appreciation, Elon Musk's start-up electric car company Tesla Motors was named after the visionary inventor in 2003.

    Sandra Cisneros was born in Chicago in 1954 to a Mexican American family. As the only girl in a family of seven children, she often felt like she had "seven fathers ", because her six brothers, as well as her father, tried to control her. Feeling shy and unimportant, she hid herself into books. Despite her love of reading, she did not do well in elementary school because she was too shy to participate.

    In high school, with the encouragement of one particular teacher, Cisneros improved her grades and worked for the school literary magazine. Her father encouraged her to go to college because he thought it would be a good way for her to find a husband. Cisneros did attend college, but instead of searching for a husband, she found a teacher who helped her join the famous graduate writing program at the University of Iowa. At the University's Writers' Workshop, however, she felt lonely—a Mexican American from a poor neighborhood among students from wealthy families. The feeling of being so different helped Cisneros find her "creative voice".

    "It was not until this moment when I considered myself truly different that my writing acquired a voice. I knew I was a Mexican woman, but I didn't think it had anything to do with why I felt so much imbalanced in my life, but it had everything to do with it! That's when I decided I would write about something my classmates couldn't write about."

    Cisneros published her first work, The House on Mango Street , when she was twenty-nine. The book tells about a young Mexican American girl growing up in a Spanish-speaking area in Chicago, much like the neighborhoods in which Cisneros lived as a child. The book won an award in 1985 and has been used in classes from high school through graduate school level. Since then, Cisneros has published several books of poetry, a children's book, and a shortstory collection.
