At the age of 5, Zhang Haidi suffered from high paraplegia due to spinal hemangioma. However, she was physically disabled and strong-willed, diligent in studying, and enthusiastic about helping others. She was known as the "Contemporary Paul".
Faced with the cruel challenge of fate, Zhang Haidi did not feel depressed or sinking. She fought against the disease with tenacious perseverance and perseverance, withstood severe tests and was full of confidence in life. Although she did not have the opportunity to enter school, she studied hard and completed all primary and secondary school courses. She taught herself college English, Japanese, German and Esperanto, and studied university and master's courses. On March 7, 1983, the Central Committee of the Communist Youth League held a naming and commendation meeting in Beijing and awarded Comrade Zhang Haidi, who was known as the "New Lei Feng of the 1980s", the title of "Outstanding Communist Youth League Member". In 1983, Zhang Haidi began to engage in literary creation. He successively translated "Seaside Clinic", "Little Miller's Travels" and "Rebecca at the New School", and created "Window Open to the Sky", "Questioning Life", "Wheelchair" "The Dream" and other works with more than one million words. He is currently a first-level writer in the Literary Creation Room of Shandong Writers Association. In 1993, Zhang Haidi passed the examination and thesis defense and received a master's degree in philosophy from Jilin University. Participated in the Far Southern Games in 1994. In 1997, he was selected as one of the "Five Outstanding Disabled Persons in the World" by Japan's NHK. Since 1998, he has served as the chairman of the China Association of Physically Disabled Persons. In 2000, he won the title of National Model Worker.

Stephen Hawking was born in Oxford on January 8, 1942, that day happened to be It was the 300th anniversary of Galileo's death. Perhaps because he was born during the Second World War, he was particularly fascinated by models as a child. When he was a teenager, he not only enjoyed making model airplanes and ships, but also made many different types of war games with his schoolmates, reflecting his desire to study and manipulate things. This desire drove him to pursue a PhD and make significant achievements in the study of black holes and cosmology.
When Hawking was thirteen or fourteen years old, he had made up his mind to engage in research in physics and astronomy. At the age of seventeen, he received a scholarship in natural sciences and successfully entered Oxford University. After graduating with a bachelor's degree, he transferred to Cambridge University to study for a PhD, studying cosmology. He soon discovered he had Lou Gehrig's disease, which causes muscle wasting. Because the doctors were helpless about the disease, he initially planned to give up his ideal of doing research. However, later the deterioration of the disease slowed down, and he regained his mood, overcome all difficulties, stood up from the setback, and faced this misfortune bravely. Continue your research.
In the 1970s, he and Penrose proved the famous singularity theorem, and both won the Wolf Prize in Physics in 1988. He also proved that the area of ??a black hole does not decrease with time. In 1973, he discovered that the temperature of black hole radiation is inversely proportional to its mass, that is, the black hole will become smaller due to radiation, but the temperature will increase, and eventually it will explode and disappear.
In the 1980s, he began to study quantum cosmology. At this time, he already had problems with his mobility. Later, he underwent tracheal surgery due to pneumonia, which made him unable to speak again. Now he is paralyzed and relies on an electric wheelchair to replace his legs. Not only does he need the help of computers and language synthesizers to speak and write, but even for reading, he has to have someone spread out each page of paper for him on the table for him to drive the wheelchair page by page. Go and see.
Hawking devoted his life to the research of theoretical physics and is known as one of the most outstanding scientists today. His books include "A Brief History of Time" and "Black Holes and Infant Universes and Related Articles." Although everyone thinks he is very unfortunate, his scientific achievements were achieved after he became ill. With his perseverance and unyielding will, he defeated the disease, 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.
