      Stephen Hawking is one of the famous scientists in this century. He is now wheelchair bound and unable to feed himself or get in and out of bed alone. But he has refused to give in to the condition. Now he is regarded as one of the world＇s leading authorities on cosmology. Last year he was invited to China. He impressed us  with  his  self-confident,  humorous  and  witty conversations.
