a man of iron

Zhang Haidi 1955 was born in an intellectual family in Wendeng County, Shandong Peninsula. At the age of 5, she was completely unconscious from the chest down and could not take care of herself. Doctors think that paraplegic patients like this can hardly live beyond 27 years old. Under the threat of death, Zhang Haidi realized that his life might not last long. She is sad because she has no more time to work. She cherishes every minute more and prolongs her life with diligent study and work. She wrote in her diary: "I can't live in mediocrity." If you are alive, you have to study and do more for the masses. " Since it is a meteor, we should leave the light to the world and give everything to the people. "1970, she followed her parents who led the educated youth to the countryside and settled in Shanglou Brigade in Shenxian County. Seeing the pain caused by the lack of medical care and medicine for the local people, she came up with the idea of learning medical skills to relieve the suffering of the people. She used her pocket money to buy medical books, thermometers, stethoscopes, mannequins and medicines, and studied books on acupuncture, human anatomy, internal medicine and practical pediatrics. In order to identify the internal organs, she cut open the hearts, lungs, livers and kidneys of small animals for observation. In order to be familiar with acupoints, she drew red and blue dots on herself, practiced needles on her body and felt the acupuncture sensation. Many things happen. She finally mastered certain medical skills and was able to treat some common and frequently-occurring diseases. For more than ten years, she has treated 10000 people.

Later, she moved to the county town with her parents and didn't arrange a job once. Inspired by the deeds of pavel korchagin and Wu Yunduo, and inspired by Gao Yubao's experience in writing books, she decided to take the road of literary creation and use her own pen to create beautiful images and inspire people's hearts. She has read many famous Chinese and foreign books, kept diaries, read novels, recited poems and copied zhanghua's epigrams. Besides reading and writing, she also practiced sketching, learned to sketch, copied famous paintings, learned to recognize simple music and staff, and played songs with accordion, pipa and guitar. Now he is a professional creator of Shandong Federation of Literary and Art Circles, and his work Dream in a Wheelchair came out, which once again aroused strong repercussions in the society.

Look for the goal, no matter how many difficulties and obstacles there are, we must cross the past and reach the other side of success. This is Zhang Haidi's character. Once, an old comrade brought a bottle of imported medicine and asked her to help translate the explanatory text. Seeing this comrade leaving in disappointment, Zhang Haidi decided to learn English and gain more knowledge. From then on, she wrote English words on the wall, on the desk, on the desk lamp, on the mirror, and even on her hands and arms. She also stipulated to herself that she would not sleep unless she remembered the word 10 every night. There are guests at home, as long as they know some English, they all become her teachers. After seven or eight years of hard work, she was not only able to read English newspapers and literary works, but also translated the English novel The Beach Clinic. When she handed the translated version of this book to the editor-in-chief of a publishing house, the old comrade who was over 500 years old was moved to tears and enthusiastically wrote the preface: Road, extending at the foot of a paralyzed girl.

Later, Zhang Haidi made continuous progress and learned Japanese, German and Esperanto. Haidi also tries his best to help young people around him, encouraging them to love life, cherish youth, study hard the skills of serving the people, and contribute their own light and heat to the prosperity of the motherland. Under her guidance, many teenagers have been admitted to middle schools, technical secondary schools and universities, and many lost people have been inspired and educated in her contact and become full and noble. Zhang Haidi sang a high-pitched and passionate song of life in a wheelchair. The theme of this song is: the value of human life lies in bravely pioneering and selfless dedication for the prosperity of the motherland and the happiness of the people!

(2) The story of Helen Keller

1On the afternoon of June, 968, Helen Keller died in her sleep at the age of 87. Miss Keller was deaf and blind at 18 months after birth, but miraculously finished her life.

Helen Keller 1880 was born in mbia, Tuscany, in northern Alabama. When she was one and a half years old, a serious illness deprived her of her sight and hearing, and then she lost the ability to express herself in words. However, in this dark and lonely world, she actually learned to read and speak, and graduated with honors from Radcliffe College in the United States, becoming a well-known writer and educator proficient in five languages: English, French, German, Latin and Greek. She traveled all over the United States and the world to raise money for schools for the blind and devoted her life to the welfare and education of the blind. She has won the praise of people all over the world and won many government awards.

The most important thing for a deaf-mute to learn to read is for out of the dark to move towards the light. From learning to read to learning to read requires more perseverance than ordinary people. Helen observed Miss Sullivan's lips with her fingers and understood her throat trembling, mouth movements and facial expressions with her sense of touch, which was often inaccurate. In order to pronounce a word or sentence well, she has to practice it again and again. Helen never gives in to failure.

From Helen's education at the age of 7 to her admission to Radcliffe College 14, she wrote many letters to her relatives, friends and classmates. These letters either describe what she saw and heard on the trip, or pour out her feelings, and some people repeat a story she just heard, which is very rich in content. When she was in college, many textbooks didn't have Braille, and the contents of the books in her hand had to be spelled by others, so she spent much more time previewing her lessons than other students. While other students were playing and singing outside, she spent a lot of time preparing her lessons.

Helen can achieve such high academic performance in out of the dark not only because of her perseverance, but also because of her teacher Sullivan's follow-up teaching. She said that "the day when my teacher Anne Mansfield Sullivan came to my home was the most important day in my life" and "she liberated my spirit". It was her teacher who taught her to read and know that everything has a name, and it was also the teacher who taught her what an abstract noun like "love" is. Helen became ignorant and surly after her childhood illness and disability, and almost became a hopeless waste. But it is indeed a miracle that she became a literate college student. It can be said that half of this miracle was created by Helen's teacher, Anne Sullivan, and it was the fruit of her lofty dedication and scientific educational methods. No matter what Miss Sullivan teaches Helen, she always tells it clearly with a nice story or a poem. Her educational experience is very rich and her educational methods are different. She never locked Helen in her room for strict classroom education.

Helen overcame the mental pain caused by physical defects with tenacious perseverance. She loves life. She can ride horses, ski and play chess. She also likes theatrical performances and visits museums and places of interest, from which she can gain knowledge. At the age of 2 1, she collaborated with her teacher to publish her first novel, The Story of My Life. In the next 60 years, she wrote 14 books.

(3) Hawking-a genius in a wheelchair

At the beginning of the new millennium, the White House delivered a series of speeches, among which the speech with the theme of science was Imagination and Change-Science in the Next Millennium. Its speaker is Stephen Hawking, a professor of applied mathematics and theoretical physics at Cambridge University in England, who is known as a "wheelchair genius". He is severely disabled and has only three fingers in his hand. This extremely disabled and intelligent scientist became the ideal candidate for this unusual speech.

Nicknamed "Einstein"

In the 1990s, it became fashionable to talk about cosmology. Although The Big Bang Theory is not new, it is novel in the public mind. Especially when it comes to Hawking, people show great interest and call him the best physicist since Einstein.

Hawking is English. He was born on194265438+1October 8th. This day happens to be the 300th anniversary of the death of Galileo, an Italian physicist and founder of modern physics. A few days ago was Newton's birthday:1643 65438+1October 4th. Of course, this does not mean that the little Hawkins who landed was covered with a golden halo. In Hawking's own words, "I estimate that about 200,000 babies were born on the same day".

Like ordinary children, Hawking likes toys, is fascinated by toy trains, and even buys electric trains at his own expense. When he was a teenager, Hawking also liked to make airplane models and ship models, and even tried to invent some games, such as factories that make parts with different colors, roads and railways that transport products, and stock markets. Hawking and a classmate are responsible for writing the rules of the game. When compiling these games, Hawking's goal is to "build a movable model that I can control", and "these games and productions all come from the requirements of exploring and controlling things". This requirement has always driven Hawking to "explore things" and even played a role in later cosmological research.

During school, Hawking was assigned to a good class. Although he never ranked in the top half, he was still respected by his classmates, who gave him a nickname-Einstein. There are some good students in Hawking's class. They like listening to music, especially classical music, such as Mozart, Mahler and Beethoven. They also go to the concert hall to listen to music. They also often discuss some scientific and religious issues, such as the origin of the universe and whether the operation of the universe needs the role of God.

Look at the vast universe.

In the last two years of middle school, a math teacher came to the class. His teaching was enlightening and aroused Hawking's interest in mathematics and physics. Although his father encouraged him to study science, he hoped that he would study biology similar to his father's major. Recalling his study in middle school, Hawking said, "When I was young, I treated all sciences equally. After I was thirteen or fourteen years old, I knew I would do research in physics, because it was the most basic science, although I knew that middle school physics was too easy, too simple and too boring. Chemistry is much more interesting, and many unexpected things keep happening, such as explosions and so on. But physics and astronomy are expected to solve the problem of where we come from and why we are here. I want to explore the secrets of the universe. " It can be seen that although the young Hawking's ambition is not ambitious, "wanting to explore the inner details of the universe" will definitely have an impact on his later research.

After graduating from high school, Hawking was admitted to Oxford University and won a scholarship as his father wished. Hawking didn't study physics hard, and later he was admitted to the doctoral program of theoretical physics at Cambridge University. Why did you choose the major of theoretical physics? Hawking later said: "theoretical physics has two basic fields ... one is to study very large-scale, that is, cosmology;" The other is to study very small scales, that is, elementary particles. " In other words, theoretical physics links the "largest" universe with the "smallest" elementary particles. Finally, he decided to study cosmology because "there is a well-defined theory in cosmology, namely Einstein's general theory of relativity". General relativity is the theoretical basis of studying cosmology.

Repay the kindness of society

Hawking got a strange disease during his school days, which is a motor neuron disease. This disease made Hawking, who was already inflexible, more clumsy and his condition deteriorated rapidly. Hawking was so sad that he thought he would not live long. However, Hawking did not give up the work, study and life of normal people. He got married at this time. Five years later, he became the father of three children.

Hawking, who is sick, remains the same and even more diligent. He once dreamed that he was executed, from which he hoped that "if I was pardoned, I could do many valuable things". He believes that "I will sacrifice my life to save others" and do some good deeds to repay the kindness of society to him.

Hawking has made great achievements because of his hard work. He is famous in physics for his study of black holes. A black hole is a very small and massive celestial body, that is, it has a high density. This celestial body is theoretically inferred.

As early as 200 years ago, a French scientist put forward the problem of black holes. He believes that stars that meet certain conditions will absorb their own light under the action of gravity, making us look like a "dark mass". However, this sci-fi prediction has not been taken seriously. When Einstein established general relativity, a German scientist re-predicted the existence of black holes with the help of general relativity. He found that a black hole with a mass equal to the mass of the sun is only 2.95 kilometers in diameter; A black hole equivalent to the mass of the earth is only 0.9 cm in diameter. In the late 1930s, an American scientist studied the problem of black holes while studying the evolution of stars. He believes that when the star burns out, under the action of gravity, the star will collapse endlessly and eventually form a black hole.

The study of black holes has attracted worldwide attention.

In 1960s, a series of new discoveries in astronomy stimulated the research of astrophysics. Hawking came at the right time, and his research on black holes made him emerge. Hawking introduced heat into the study of black holes, which greatly deepened the understanding of black holes. At this time, Hawking thinks that there may be a kind of "miniature black hole". This kind of black hole is very small, and some will be as small as protons or neutrons. According to the theory of modern physics, when an object is so small, it should obey the laws of quantum mechanics. Hawking's further research shows that black holes can evaporate; The smaller the black hole, the faster it evaporates. 1 black hole 1 100 million tons (with similar proton size) 1 000 million years can be completely evaporated, and the energy released at last 0. 1 second is equivalent to110,000 megaton hydrogen bomb explosion. In other words, should we carefully observe astronomy and try to find this kind of "miniature black hole" in space and use it? !

Hawking made great contributions to the study of the Big Bang theory. He believes that the universe originated from a "singularity", the explosion at the "singularity" produced particles and energy, and the interaction between particles produced nebulae, which then evolved into our world today. Today's universe is still expanding, and the future universe may continue to expand, or it may shrink to the "singularity" that originally formed the universe when it reached its limit. It seems interesting, but this is the level of people's understanding of the universe today.

Hawking won the Einstein Prize of 1978 because of his achievements in astrophysical research. 1980 Became Lucas Chair Professor of Trinity College. Newton used to be the professor of this lecture. Now, Hawking is almost sixty years old. Although he is physically disabled, he often travels, speaks and writes. His A Brief History of Time has been published in tens of millions of copies and translated into more than 40 languages. Because of Hawking's legendary struggle experience, his A Brief History of Time has also been put on the screen. People saw pictures of black holes and elementary particles, and heard Hawking's tapping on the computer keyboard and computer synthesis. People are shocked by the abstinence of modern physics and the theory of the universe, sigh for the wisdom of human beings, and admire Hawking's great spirit of climbing the scientific peak even if he suffers great pain.

I hope it helps you.
