Facing the cruel challenge of fate, Zhang Haidi didn't feel depressed and sink. She fought against the disease with tenacious perseverance and perseverance, withstood severe tests and was full of confidence in life. Although she didn't have a chance to enter the school, she studied hard, completed all the courses in primary and secondary schools, taught herself college English, Japanese, German and Esperanto, and studied the courses of universities and graduate students. 1983 On March 7th, the Bureau of the Central Committee of the Communist Youth League held a naming commendation meeting in Beijing, and awarded the title of "Excellent League Member" to Comrade Zhang Haidi, who was known as "the new Lei Feng of the 1980s". From 65438 to 0983, Zhang Haidi began to engage in literary creation. He translated The Seaside Clinic, Little Miller's Travels and Rebecca's New School successively, and created works of more than one million words, such as Windows Open to the Sky and Life and Dreams in Wheelchairs. Now he is a first-class writer in the literary creation room of Shandong Writers Association. 1993 Zhang Haidi passed the examination and thesis defense, and obtained a master's degree in philosophy from Jilin University. 1994 participated in the Far South Games. 1997 was selected as "the five outstanding disabled people in the world" by NHK in Japan. 1998 so far, he is the chairman of China Disabled Persons' Association. Won the title of national model worker in 2000.

Stephen? Stephen Hawking was born in Oxford on1June 8th, 942 and 65438+1October 8th, exactly 300 years after Galileo's death. Probably because he was born in the era of World War II, he was particularly fascinated by models when he was a child. When he was a teenager, he not only liked making model planes and ships, but also made many different kinds of war games with his classmates, reflecting his desire to study and manipulate things. This desire drove him to pursue a doctorate and made great achievements in the study of black holes and cosmology.
Hawking made up his mind to study physics and astronomy when he was thirteen or fourteen. At the age of seventeen, he won a natural science scholarship and successfully entered Oxford University. After graduating from bachelor's degree, he transferred to Cambridge University to study cosmology. Soon, he found himself suffering from Luger's disease, which can cause muscle atrophy. At first, he intended to give up the ideal of engaging in research, because doctors were helpless about the disease, but later, the rate of deterioration slowed down, so he regained his mood, overcame all difficulties, stood up from setbacks, bravely faced this misfortune and continued to indulge in research.
In 1970s, he and Penrose proved the famous singularity theorem, and won the Wolff Prize for Physics with 1988 * *. He also proved that the area of black holes will not decrease with time. 1973, he found that the temperature radiated by a black hole is inversely proportional to its mass, that is, the black hole will become smaller due to radiation, but the temperature will rise and eventually explode and disappear.
In the 1980s, he began to study quantum cosmology. At this time, there was something wrong with his movements. Later, because of pneumonia, he had a tracheal puncture operation, which made him unable to speak again. Now he is completely paralyzed, so he can only replace his feet with an electric wheelchair. He not only relies on computers and language synthesizers to speak and write, but also needs others to spread out every page on the table for him to read page by page in a wheelchair.
Hawking devoted his life to the study of theoretical physics and is considered as one of the most outstanding scientists today. His works include Time, Black Hole and A Brief History of baby universes and related articles. Although everyone thinks he is unfortunate, his achievements in science were obtained after his illness. With his indomitable will, he overcame his illness, created a miracle and proved that disability is not an obstacle to success. His love for life and enthusiasm for scientific research are worth learning from the younger generation.
