it is a huge loss to all human beings that stephen hawking, a great visionary physicist, has passed away. he has been so famous and renowned that almost evening knows his research of black holes and relativity and his books, especially A Brief History of Time. when he was about 20 years old, he was diagnosed with a rare form of motor neuron disease. gradually, he began to lose the ability to speak and have to use a voice synthesizer. everytime i saw his name in The Big Bang Theory i always felt  sad though i was not deep saddened as his families did. i am wondering what kind of condolence we say could show our respect and laud him simultaneously. his body was so small but his brain was so broad that the cosmology has been put in. his body couldn't move, but his spirit could fly, flying in the quantum mechanic. now  his "sacking" by death made him free to go to university. his death has stirred up a strong feeling of sadness not hatred. his is so great that i am afraid the insurgents in rebel-held regions would also feel a little saddened, who would be a beast in wars and make some genocide.
