The world has lost one of its brightest stars, British physicist(物理学家) Stephen Hawking died on March 14 , at the age of 76.
Hawking is probably the world’s most famous scientist after Albert Einstein. He is an expert on black holes . He has devoted his whole life to digging into the beginning and the end of the universe. “My goal is simple,” Hawking once said. “It is to completely understand the universe(宇宙), why it is as it is and why it is there at all.”
Hawking’s achievements are even greater if you think about his disability（残疾）. When he was 21, Hawking caught a bad illness that slowly stopped him from moving or talking. For a period of time, he had no way to communicate except by blinking(眨眼). Later he sat on a wheelchair with a computer by his side. To communicate, he moved two fingers to control the computer’s mouse. He selected his words from the screen, which were then spoken by a voice synthesizer(音响合成器).
“I have had the disease for most of my life,” Hawking once said, “Yet it has not stopped me from being successful at my work.”
Though Hawking was a disabled man , he made great achievements . He received many awards and prizes
for his work during his lifetime. This included winning the Albert Einstein Award, which stands for the highest achievement in theoretical(理论的) physics.
Despite the fact that he is no longer with us, his legacy （遗赠）will surely live on. As Sajid Javid, a UK
government minister, put it, “A brief history on Earth; an eternity（永恒的） in the stars.”
