Brief introduction Chen Shengshen (191120041October 28th to1February 3rd), born in xiushui county, Jiaxing, Zhejiang, Han nationality, Chinese American, international mathematician, famous educator. When he was a teenager, he showed his talent in mathematics. In his mathematical career, after several choices and difficult climbing, he finally became brilliant. His outstanding contribution to global differential geometry influenced the development of mathematics as a whole, and he was praised by Yang Zhenning as another landmark figure after Euclid, Gauss, Riemann and Gadang. He presided over and founded three mathematical research institutes and trained a group of world-renowned mathematicians. 1984 won the Wolf Award in May. Chinese mathematical society passed a resolution in 1985 to establish the Chen Shengshen Prize in Mathematics. He is the only person from China who won the Wolff Prize, the highest honor in mathematics. He is regarded as the greatest mathematician of our time and the father of differential geometry by the international mathematical community. Wei Yi once said, I believe that the future history of differential geometry will definitely consider him as the heir of Tang Jia. I love my hometown in my later years, and I return to the Institute of Mathematics of Nankai University in Tianjin every year to take charge of my work and cultivate new people, just to realize my dream: to make China a great mathematical country in the 2 1 century.
well-known saying
Our hope is to see China become a great mathematical country in 2 1 century.
I will devote myself to the Institute of Mathematics until I die.
We should do something for our reason. We should do something for the people of China.
The most important component of a researcher is a great scholar, and there is nothing else.
biography
From June, 5438 to February, 2004, Chen Shengshen, a 93-year-old world-class master of mathematics and the father of differential geometry, passed away, stopping beautiful calculation forever. His mathematics is recognized as the most beautiful and pure, and his life is recognized as the simplest and most certain. You only do one thing in your life, and you can only do one thing in your life. This is Master Chen Shengshen. He identified mathematics and devoted his life to it, and finally stepped into the sacred palace of mathematics and became a hero of the mathematics kingdom.
In college, Mr. Chen Shengshen made the most important choice in his life, that is, majoring in mathematics. After graduation, Chen Shengshen, aged 19, was admitted to Tsinghua University for a master's degree with excellent results. Because differential geometry has not been offered in Tsinghua, Chen Shengshen didn't really start to contact this course during his stay in Tsinghua. But he learned about differential geometry from other places and was full of yearning for it. He once described his feelings in Tsinghua: At that time, he was looking at a beautiful mountain from a distance and didn't know how to climb it. Later, by chance, Chen Shengshen heard about the differential geometric topology of W. blaschke, a mathematician at Hamburg University, and decided to study in Hamburg. At that time, the United States returned the balance of Yu Zi's compensation, and the students funded by this money were going to study in the United States. At that time, many international students were generally willing to go to the United States, but Chen Shengshen thought that studying mathematics must go to Germany. This is his active choice again. With his persistence and the help of his predecessors, he finally got his wish.
The choice of Hamburg Road made him lucky enough to get in touch with the thoughts and academics of the greatest mathematicians in the world, such as blaschke, Keller and Gadang. When we set up a seminar on Tang Jia-Keller Theorem in Hamburg University, almost everyone came at first, but because it was difficult to understand, Chen Shengshen was left alone, and later he understood the charm of Tang Jia.
After returning to China, Chen Shengshen wrote a story in an article: once he and his wife visited the Lohan Pagoda, and after watching it, they suddenly felt that they were no better at math, at most, it was the Lohan Pagoda. Everyone knows the name of the Bodhisattva, but no one knows who that person is. So don't take fame and fortune too seriously. He thinks that the bodhisattva of mathematics is riemann sum Poincare. Riemann has continuously opened up the space of mathematics, and Poincare has expanded the plane and space of mathematics to N dimensions, because with these two, other people's work can only be ocean.
Chen Shengshen never follows the fashion, does not grab the hot spot of study, and fame and fortune have never been his pursuit. I have no ambition to study mathematics, I just want to know mathematics. If a person's goal is fame and fortune, mathematics is not a shortcut. Chen Shengshen said that there are many simple and difficult problems in mathematics. These problems make people forget to eat and sleep for years or years. Once they find the light, their happiness is indescribable. This is a quiet world, there is no grand prize, and it is also an equal world.
In his later years, Mr. Chen Shengshen not only continued his favorite mathematics research, but also often visited some young children to encourage them to study hard and make contributions to the prosperity of the motherland. Every time I talk to teenagers, Mr. Chen Shengshen will mention the word "single-minded". He once said: Only with one heart and one mind can one thing be done thoroughly! What does it mean to be single? Being single-minded means doing only one thing in your life. What's wrong with doing only one thing in your life? This is the best way to achieve results.
I only do one thing in my life. It can be said that Mr. Chen Shengshen is such a person. He struggled in the kingdom of mathematics all his life and made brilliant achievements. He also explained the theory of success with his own life.
arouse
From the introduction of mathematics to the death of a man in his twenties at the age of 93, Mr. Chen Shengshen said that his brain has been working for mathematics for more than 70 years. He built a magnificent building in the kingdom of mathematics. As he himself said, he can only do one thing in his life, that is, mathematics. There are not many wonderful things in the world, and mathematics is one of them. Chen Shengshen is very single-minded about mathematics. Because of his single-mindedness, he made a brilliant life for the master of mathematics.
Brief introduction of Gentiana scabra
Gentiana is an ornamental herb. In fact, everyone may have heard of the name Qin Genting, but what is Qin Genting like?

Edison profile
Edison Introduction Edison: Genius is one percent inspiration and ninety-nine percent perspiration.
Thomas Alva Edison is a world-famous American electrician and inventor. He was born on 1 February, 8471day, and was born in Milan, Ohio, in the midwest of the United States. My father is descended from Dutch, and my mother is a primary school teacher, descended from Scots. Edison entered school at the age of eight, and after only three months of study, he would drop out of school and go home. His mother, who had been a teacher in the countryside, helped him learn by himself. 12 years old, family life is difficult, and began to sell newspapers on the train. 16 years old, invented the automatic timer, and inventions continued. Edison had about 2000 inventions in his life. In addition to his inventions and contributions in phonograph, electric light, telephone, telegraph and film, he also has many famous creations and opinions in the fields of mining, construction and chemical industry. He has made great contributions to human civilization and progress. 1928 Edison was awarded the U.S. congressional gold medal. 193 1 year1October 18, Edison died in West Orange at the age of 84, 193 1 year1October 2, and lights were turned off all over the United States to show his condolences.
well-known saying
Life is short, and our best reward for this short life is work.
Life is short, there are too many things to -T-, and I have to race against time.
Surprise is the seed of science.
My philosophy of life is work. I want to reveal the mysteries of nature and benefit mankind.
Failure is also what I need. To me, it is as valuable as success.
Climbing high will make you feel inferior, and thinking too high will make you unable to succeed. Therefore, successful people must cultivate a cool head and focus on everything, which is the key to success.
biography
1929 10 2 years ago, all radio stations in the United States tuned their own bands to a stage, and the American people were paying attention to one thing: an exhibition was about to start in dearborn, Michigan, where the great inventor Edison would give a dramatic performance about the electric light experiment half a century ago. This was the most exciting event at that time.
On that day, 82-year-old Edison felt as if he had returned to 50 years ago. In the spacious laboratory, he stood quietly indoors, and the rectangular dining table was arranged in a zigzag shape. At the farthest end is the chairman's chair, and the honor seat in the middle is reserved for the president and his wife, but the president and his wife insist that the Edison couple be the chief.
President Hoover delivered a speech: In our country, scientists and inventors are the most precious and priceless wealth. With their creativity and piety, they gradually turned their scientific ideas into facts for everyone to appreciate. Because their efforts have promoted our progress, this great contribution is priceless.
With his genius, Mr. Edison jumped from an ordinary man to one of the great men in the world. His life gave us new confidence. We believe that people of our time can support opening the door of opportunity and letting those who are willing to go in leave.
Human civilization is like a garden, and its quality is determined by the quality of flowers. How much effort we put into making it fertile and how much effort we put into resisting destructive forces, then how many flowers we can harvest; Because of the fragrance of these lives, we are encouraged to make new efforts, give us new strength and strengthen our belief in the future.
There is no greater gathering to pay tribute to an ordinary citizen. There are 500 guests coming to the banquet, most of whom are figures in the world celebrity dictionary. Financiers, politicians, scientists, industrial giants, railway station owners, university presidents, artists and playwrights all came to welcome him. From the other side of the Atlantic Ocean, MadameCurie, the inventor of radium, and representatives of senior Japanese engineers and officials from the other side of the Pacific Ocean came. In addition, there is Wright, the pioneer of aviation. rville Wright)； Banker Kahn (. TT.H.

President of the American Federation of Trade Unions Green and others. That evening, the British Prince and German President V. von Hindenburg sent congratulatory messages. Richard. Bird, the captain of the expedition, also called to congratulate him. He sat in the ice and snow of the American base in Antarctica.
Edison made a few short remarks at the banquet. At the end of his speech, he paid tribute to Henry Ford. Edison said: I can only tell you in the most complete and appropriate sentence that he is my friend.
Good night, everyone. The king of invention, perhaps excited and tired at the same time, suddenly changed his face, and the onlookers immediately recruited President Hoover's doctor to give him a shot in the arm. Everyone helped Edison to the next room and had a rest. He gradually got better.
Edison's health went from bad to worse after his trip to dearborn. But from 1930 to 193 1, he still insisted on making decisions for the company as much as possible.
In June, the United States was in the Great Depression. Edison sent an enthusiastic telegram when he learned that there was an electric light conference in Atlantic City. What I want to tell you is courage and diligence, he told the representatives of the electric light club in a telegram. It took me a long time to see that history is repeating many depressions in industry and commerce. But after every depression, America became stronger and more prosperous. You should be as hardworking and brave as your parents, keep your faith and go forward bravely.
This may be Edison's last telegram. In July, he arrived at the rubber cultivation test site in California. This rubber tree cultivated in the past is only one meter high. The amount of rubber collected is also very small, but it can grow to 3 meters high after research and improvement. In another five years, the rubber needed by the United States will not need to be imported from abroad. Edison said this to his colleague who works in the proving ground.
In August, Edison was seriously ill, and the doctor diagnosed him with various symptoms of Brett's disease, uremia and diabetes. It is estimated that he will not live for a few days, but the doctor announced that in order to take care of the public's mood, Mr. Edison can be compared to a ship sailing into a narrow waterway. He may get through it safely. Or touch rocks. However, this statement did not reassure the people of the whole country. Surprisingly, Edison's danger passed quickly, and there was no need to make an announcement every day. A few days later, he returned to the habit of driving around the corner every afternoon.
At the beginning of September, Edison's illness entered a critical period again, but he survived again. When he asked the doctor what the medicine would do, he was only disappointed that he didn't recover soon. On October 4th, 65438/kloc-0, the doctor concluded that his illness was irreversible. People from all over the world visit him every day. The Pope sent two telegrams asking about his health. President Hoover carefully informed Edison of his illness by telephone every day. A large number of letters and telegrams of sympathy poured into the room. The Chamber of Commerce in Fort Myers decided to take Sunday, 654381October 4th as a day to pray for Edison's recovery.
Nine days passed without any liquid. 120 hours, I only drank 6 teaspoons of pear juice.
Edison fell into a coma. Before that, he looked into the valley through the bedroom window. At the beginning of 19, he played with the children. At that time, he said with a smile, it is really beautiful there. Before that, he also met with foyle Si Tong. With a triumphant smile, he showed foyle Si Tong four tire samples, which were made of rubber extracted from compositae plants in the house.
193 1 year1October 18, at 3: 24 am on Sunday, the great inventor Edison completed his 84-year great life journey.
On his deathbed, he said: from birth to death, you need hard work and diligence all your life. I have done my best for the happiness of mankind, and there is nothing to regret!
Three days later, on the night of June 2nd, 10, the great inventor's body was buried under a big rubber tree near his home in West Orange Creek.
As soon as the news came out, people fell into great sorrow. At that time, lights were turned off for a minute in all parts of the United States to express their condolences.
In this minute, Chicago, California, Denver, new york, and the entire Mississippi River were plunged into darkness. Broadway is dark, and so is the world. Then, from the east coast to the west coast, from the city to the countryside, the lights are bright and bright as day, and the world is bright.
People pay tribute to Edison, among which President Hoover's words are the most touching.
He said: All Americans are the beneficiaries of Edison! We not only accept his benefits and benefits in life, but most importantly, we inherit his spiritual legacy! Edison started as a newsboy and telecom operator, but in the end, he ended his brilliant life as a human mentor. Edison's personal belief is an inexhaustible spiritual wealth for our descendants! He is modest, friendly and always does things. Edison taught us that we can achieve our goals as long as we make unremitting efforts. This is the most precious legacy he left us!
arouse
From birth to death, you need hard work and diligence all your life. I have done my best for the happiness of mankind, and there is nothing to regret! This last sentence is the best summary of Edison's life. Edison's life is a life of invention, creation and diligence.
Diligence is not a strange word for us, but in our daily study and life, who can really be diligent and make unremitting efforts to achieve our goals? Some people say that I have a smart brain and everything can be easily solved by me. Some people say that as long as I master effective methods and skills, diligence is not very important. In my opinion, no matter whether you are smart or not, whether you have mastered effective methods and skills, you need to work hard to achieve your goals and ideals.
A reporter once asked Edison: You are a great inventor, and the American people admire you very much. They want to know whether your success depends on genius. Edison smiled and said, genius? Genius does not necessarily succeed. Genius is only one percent inspiration and ninety-nine percent perspiration. Obviously, Edison wanted to tell people that talent may be important, but what is more important is diligence and hard work. People live in this world in order to do something useful to society to show their life value and prove that they are worth coming to this world. However, we are just used to seeing the success and glory of others and seeing the prosperity of others. I don't know how much diligence, hard work and sweat behind this success have made today's glory.
Everyone is created equal. The reason why some people succeed in the future and make contributions to society, while others are doomed to remain unknown all their lives and even become a burden to society is because successful people understand that they must work hard to succeed.
Introduction to Lawrence
Lawrence Lawrence Introduction: Tolerance is a virtue
D.H. Lawrence (1885~ 1930) is the most unique and controversial writer in Britain in the 20th century. He is regarded as one of the greatest figures in the history of English literature. Lawrence was born in Eastwood, Nottinghamshire. His father is a coal miner and his mother is a primary school teacher. After graduating from high school, Lawrence worked as a shop assistant and taught, and then entered Nottingham University College for teacher training. Genius is the right word to describe Lawrence. At that time, British society attached great importance to people's birth and growth. Since the Victorian era, puritanism has still permeated the society. Lawrence, who grew up in this era, is different. Ford maddox Reckless, the first critic of Lawrence in history, commented on him like this: He was a genius, a genius soaked with lust.
Lauren's first novel, The White Peacock. Ck) published in 19 1 1 year. The autobiographical novel S. nsandL .Vers (19 13) is the most influential of his early works. 19 12, Lawrence eloped to Italy with Frida, the wife of a professor from Nottingham University, and married her two years later. After their marriage, Lawrence and his wife lived in England, but during the First World War, Frieda's German background and Lauren's new anti-war sentiment made their relationship with the British authorities very tense, so they had to return to Italy. During this period, Lawrence wrote his two most successful novels, TheRainb. W, 19 15) and the woman in love (W. meninL .ve, 192 1). These two works strongly criticize capitalist industrial civilization. After 19 19, due to health reasons, Lawrence has been traveling and has been to Ceylon, Australia, Mexico and some countries in continental Europe, and created Kangaroo (Kan, gar) with these places as the background. , 1923) and feathery Serpen (T, 1926). After 1926, he lived in Italy most of the time, where he wrote his most controversial novel "LadyChatterLeysL". Version 1928). 1930 In March, Lawrence died of tuberculosis in Vance town, southeast France. Besides novels, Lawrence has also made great achievements in the creation of short stories. In addition, he also wrote a lot of poems, comments, essays and so on. He is a versatile writer.

biography
1929, that is, one year before Lawrence's death, he wrote a letter to his eldest son in Vance, France, urging him to learn tolerance, saying that it would be of great help to his life. The content of the letter is as follows: Dear son, in this letter, I want to exchange views with you on the tolerance you talked about. I think whether a person has an open-minded attitude is not a trivial matter, it is not only related to his work and study, but also related to himself.
Tolerance is a kind of temperament, showing patience and aboveboard attitude towards people who have different opinions, habits and beliefs.
Being open to new ideas and information is not just to make your personality more attractive. Although there is a close relationship between tolerance and wit, tolerance is more difficult to distinguish than wit. You may not learn all the new ideas you come into contact with, but you can study them and try to understand them.
