The person I respect most is the remarkably geophysicist Huang Danian, that helped China to make many technological advances. Huang had studied and worked in Britain for 18 years, but when his country needs him, he insisted that he returned to China. Over the next seven years, Huang devoted himself to develop many devices needing for deep-Earth exploration. Unfortunately, due to the pace of his research, Huang was absent at his father's funeral, and even if his own cancer went undetected. To sum up, Huang sacrificed nothing for his research, I think people should honor him.
