Introduction to Chen Shengshen
Chen Shengshen. Only do one thing in life
Introduction Chen Shengshen (October 28, 1911 to December 3, 2004), born in Xiushui County, Jiaxing, Zhejiang, Han nationality, Chinese-American, international mathematics master, famous educator He is a foreign academician of the Chinese Academy of Sciences, the founder of Into the Wonderful Mathematics Garden, and a world-class geometer in the 20th century. He showed his mathematical talent in his youth. In his mathematical career, he made many choices and worked hard to achieve glory. His outstanding contributions to overall differential geometry have influenced the development of mathematics as a whole, and he was praised by Chen Ning Yang as another milestone figure after Euclid, Gauss, Riemann, and Cartan. He has chaired and founded three major mathematics research institutes, creating a number of world-renowned mathematicians. Won the Wolf Prize in May 1984. The Chinese Mathematical Society passed a resolution in 1985 to establish the Chen Shengshen Mathematics Award. He is the only Chinese in history to win the Wolf Prize, the highest honor in mathematics. He is known as the greatest mathematician of our time and is respected by the international mathematics community as the father of differential geometry. Weil once said that I believe that the future history of differential geometry will definitely regard him as the successor of Cartan. In his later years, he fell in love with his hometown and returned to Tianjin every year to preside over the work of the Institute of Mathematics of Nankai University and train new talents, just to realize a dream in his heart: to make China a major mathematical country in the 21st century.
Famous Quotes
Our hope is to see China become a major country in mathematics in the 21st century.
I will devote myself to the Institute of Mathematics until my death.
You should do something for your ideal. Do something for the Chinese people.
The most important ingredient for a researcher is a great scholar, and nothing else is needed.
Biography
In December 2004, ninety-three-year-old Chen Shengshen, a world-class mathematics master and the father of differential geometry, passed away and stopped his beautiful calculations forever. His mathematics is recognized as the most beautiful and pure, and his life is recognized as the most simple and stable. He only does one thing in his life. This is the master Chen Shengshen. He believed in mathematics and devoted all his life to finally entering the sacred hall of mathematics and becoming an eternal hero in the kingdom of mathematics.
In college, Mr. Chen Shengshen made the most important choice in his life, which was to major in mathematics. After completing his undergraduate degree, 19-year-old Chen Shengshen was admitted to Tsinghua University to study for a master's degree with excellent results. Because Tsinghua University has not yet opened a differential geometry course, Chen Shengshen did not really start to get into contact with this course during his time at Tsinghua University. However, he learned about differential geometry from elsewhere and became fascinated by it. He once described his mood at Tsinghua University in this way: My mood at that time was that I was looking at a beautiful mountain in the distance and didn’t know how to climb it. Later, by chance, Chen Shengshen heard the topological problems of differential geometry written by W. Blaschke, a mathematician from the University of Hamburg in Germany, and decided to study in Hamburg. At that time, the United States returned the balance of the Yuzi indemnity, and the students funded by this money were required to study in the United States. Many international students at that time were generally willing to go to the United States, but Chen Shengshen believed that to study mathematics, he had to go to Germany. This was another active choice on his part. With his persistence and the help of his seniors, he finally got his wish.
The choice of the Hamburg road gave him the opportunity to come into contact with the ideas and scholarship of the world's greatest mathematicians such as Blaschke, Keller, and Cartan. When the Cartan-Keller theorem seminar was held at the University of Hamburg, almost everyone came at first, but because it was difficult to understand, only Chen Shengshen was left. It was then that he understood the charm of Cartan.
After returning to China, Chen Shengshen wrote a story in an article: Once he and his wife visited the Luohan Pagoda. Looking at it, he suddenly sighed: No matter how good you are in mathematics, you can only be a good student. Arhat. Everyone knows the name of the Bodhisattva, but no one knows who the Arhat is. So don't take fame and fortune too seriously. He believed that the bodhisattvas of mathematics were Riemann and Poincaré. Riemann continuously opened up the space of mathematics, and Poincaré extended the plane and space of mathematics to N dimensions. Because of these two people, other people's work can only be like that of Arhat.
Chen Shengshen never followed the latest trends or sought after the most popular things when it came to learning. Fame and wealth were never his pursuit. I don’t have any ambition to study mathematics. I just want to understand 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 sleepless and unsettled for years or years. Once the light is discovered, the joy is indescribable. This is a quiet world with no big prizes and a world of equality.
In his later years, in addition to continuing his beloved mathematics research, Mr. Chen Shengshen often visited some young children and encouraged them to study hard and contribute to the prosperity of the motherland. Every time he talks with teenagers, Mr. Chen Shengshen will mention the word "focus". He once said this: Only by being focused can one do something well and thoroughly! What does single-mindedness mean? Single-mindedness means doing only one thing in your life. How can you do it poorly if you only do one thing in your life? This is the best way to achieve results.
He only does one thing in his life. It can be said that Mr. Chen Shengshen himself is such a person. He struggled in the kingdom of mathematics all his life and made brilliant achievements. He also used his life to interpret the professionalism. The success theory of achieving brilliance once and for all.
Enlightenment
From the time he was introduced to mathematics in his 20s until his death at the age of 93, Mr. Chen Shengshen said that his brain has been engaged in mathematical calculations for more than 70 years. He built a magnificent edifice in the kingdom of mathematics. Just as he said, he will only do one thing in his life, which is mathematics. There are not many wonderful things in the world, and mathematics is one of such wonderful things. Chen Shengshen was dedicated to mathematics. Because of his concentration, he achieved a brilliant life as a master of mathematics. Introduction to Gentian
Gentian is an herbaceous plant with relatively ornamental value. In fact, you may have heard the name Gentian, but what does Gentian look like?
Another name for gentian
Gentian is also called gall grass, grass gentian, mountain gentian, and gentian grass.
Growth habits of Gentian
Gentian prefers a cooler climate and a humid environment, and the soil is generally acidic.
The ornamental value of gentian
The ornamental value of gentian is still there. Some of its varieties are quite ornamental, such as ornate gentian, fringed gentian, etc., with colorful and beautiful flowers.
Gentian propagation method
When propagating gentian, people mostly propagate by sowing, which requires good light and humidity.
The second step is root propagation, which is carried out in autumn. Dig out the rhizomes of gentian, cut them and plant them.
In addition, it can also be used for cuttings. Introduction to Edison
Introduction to Edison
Edison: Genius is one percent inspiration and ninety-nine percent perspiration
Introduction to Thomas Alva Edison He is a world-famous American electrician and inventor who was born on February 1, 1847 in the small town of Milan, Ohio, in the midwestern United States. His father is of Dutch descent, and his mother worked as a primary school teacher and is of Scottish descent. Edison entered school at the age of 8. He only studied for three months before he had to drop out and go home. His mother, who had been a rural teacher, tutored him in self-study. When he was 12 years old, his family life was difficult, so he started selling newspapers on the train. When he was 16 years old, he invented the automatic timer, and inventions continued to come out after that. Edison made about 2,000 inventions in his lifetime. In addition to his inventions and contributions in phonographs, electric lights, telephones, telegraphs, movies, etc., he also had many famous creations and insights in mining, construction, chemical industry and other fields. He made great contributions to human civilization and progress. In 1928 Edison was awarded the U.S. Congressional Gold Special Medal. On October 18, 1931, Edison died in West Orange at the age of 84. On October 2, 1931, the lights were turned off across the United States to express condolences.

Biography
On October 2, 1929, all radio stations in the United States were tuned to the same station, and people across the United States were paying attention to one thing: Dearborn, Michigan An exhibition is about to begin, where the great inventor Edison will hold a dramatic performance about his electric light experiment half a century ago. This was the most exciting event at the time.
That day, the 82-year-old Edison felt as if he had returned to 50 years ago. He stood quietly in the large laboratory, with rectangular dining tables arranged in a line. At the far end is the chairman's seat, and the honorary seat in the middle is reserved for the president and his wife, but the president and his wife insisted on letting Edison and his wife sit in the first place.
President Hoover gave a speech: In our country, scientists and inventors are the most valuable and priceless treasures. With their creativity and devotion, they gradually turn their scientific ideas into facts for everyone to enjoy. Because their efforts have contributed to our progress, this great contribution is immeasurable.
Mr. Edison rose from an ordinary beginning to become one of the great figures in the world by virtue of his genius creations. His life gives us a new confidence. We believe that the figures of our time will be able to support the opening of the door of opportunity and let those who are willing to enter leave.
Human civilization is like a garden, its quality is determined by the quality of its flowers. How much energy we spend on cultivation makes it fertile, and how much strength we spend on defending against destructive forces, then we can harvest as many flowers as we can; and because of the fragrant fragrance of these lives, it encourages us to engage in new projects. Work hard to give us new strength and strengthen our belief in the future.
There is no greater gathering to pay tribute to an ordinary citizen than this one. There were 500 guests who came to the banquet. Most of these guests were characters in the "Dictionary of World Celebrities". Financiers, politicians, scientists, industrial magnates, railway station directors, university presidents, artists, and dramatists all came to welcome him. From the other side of the Atlantic came Madame Curie, the inventor of radium, and from the other side of the Pacific came A representative of Japan's senior engineers and officials. In addition, there are aviation pioneer Wright (.rville Wright); banker H. Kahn (.tt. H. Kahn); station director Daniel Willard; Miss Adams (Jane Addams) of Chicago's Hull Institute; film industry giant Willhays; the great philanthropist Julius R. Senwald; the electrical engineer Dr. E.F. Alexanders.n; the former ambassador to Turkey Morgan Tao (Henry M.rgenthan); the humorist Wheelloge Will R.gers; steelmaker Charles Schwab; former ambassador to Germany James W. Gerard; General Electric manager Gerard Swope; New York Times publisher Oakes (Ad.lphS.chs); William C. Green, Chairman of the American Federation of Trade Unions, and others. That evening, the British Prince and German President V. n Hindenburg both sent congratulatory messages.
Also calling to congratulate was expedition leader Richard E. Byrd, who was sitting in the ice and snow at the U.S. base in Antarctica.
Edison spoke briefly at the banquet, and at the end of his speech he paid tribute to Henry Ford. Edison said: I can only tell everyone that he is my friend in one sentence with the most complete and appropriate meaning.
Good night to you all. The king of inventions, perhaps a mixture of excitement and fatigue, suddenly changed his face. Onlookers immediately called President Hoover's doctor to inject him with a cardiac stimulant. Everyone helped Edison to the next room, and he gradually got better after resting for a while.
After the Dearborn trip, Edison's health deteriorated. However, from 1930 to 1931, he still insisted on making decisions for the company by himself as much as possible.
In June 1931, the United States was in the Great Depression. When Edison learned that an electric lighting conference was taking place in Atlantic City, he sent an enthusiastic telegram. In his telegram, he said to the representatives of the Electric Light Society: What I want to say to you is to be brave and to be diligent. I have spent a long time and seen history repeat itself through many depressions in industry and commerce. But after each depression, America emerged stronger and more prosperous. You must be as diligent and courageous as your fathers, firm in your beliefs, and move forward.
This was probably the last message Edison sent. In July, he arrived at the rubber cultivation test site in California. The rubber plant cultivated in the past was only one meter high. The amount of glue collected is also very small, but after research and improvement, it can grow up to 3 meters high. In another five years, the rubber needed by the United States will no longer have to be imported from abroad. Edison said this to his colleagues working at the proving ground.
In August, Edison's condition worsened, and doctors diagnosed him with various symptoms of Bright syndrome, uremia and diabetes. It was estimated that he could not last more than a few days, but the doctor, in order to take care of public sentiment, announced that Mr. Edison could be compared to a ship sailing into a narrow waterway. He might make it through safely. You may also hit a rock. However, this statement did not reassure the people across the country. Amazingly, Edison's danger soon passed, and announcements no longer needed to be made every day. After a few days, he resumed his habit of taking a walk every afternoon.
In early September, Edison's condition entered a critical stage again, but he once again overcame the difficulties. When he asked his doctor what the prescribed medicine would do, he was disappointed that he did not recover quickly. On October 4, doctors concluded that his illness was irreversible. People from all over the world come to visit him every day and every hour. Two telegrams were sent from the Pope inquiring about his health. President Hoover informed him of Edison's condition by phone every day. A large number of condolence letters and telegrams were constantly sent into the room. The Fort Myers Chamber of Commerce has decided to observe Sunday, October 4th, as a Day of Prayer for Edison’s Recovery.
Nine days have passed without any liquid intake. In 120 hours, I only drank 6 teaspoons of pear juice.
Edison fell into a coma. Before that, he had looked towards the valley through the window of his bedroom, where he played with his children in the early 19th century. At that time, he smiled and said: It's so beautiful there. Before that, he also met with Feierstone. With a victorious smile, he pointed to Feierstone with four tire samples made of rubber extracted from the Compositae plant placed in the room.
At 3:24 a.m. on Sunday, October 18, 1931, the inventor Edison completed his 84-year great life journey.
On his deathbed, he said: From birth to death, the entire life requires hard work and diligence. I have done my best for the happiness of mankind, and there is nothing to regret!
Three days later, on the evening of October 2, the inventor's body was buried under a large rubber tree near his home in West Orange.
As the news spread, people fell into extreme sadness. At that time, lights were turned off for one minute across the United States as a sign of mourning.
In this minute, Chicago, California, Denver, New York, and the entire Mississippi River went dark.
Broadway in New York is dark, and the world is dark. Then, from the east coast to the west coast, from the city to the countryside, the lights were bright, as bright as day, and the world was bright.
People paid tribute and praised Edison one after another. Among them, President Hoover’s words were the most touching.
He said: All Americans are beneficiaries of Edison! Not only do we accept his favor and benefits in life, but the most important thing is that we inherit his spiritual legacy! Edison started out as a newsboy and telecom operator, and finally ended his glorious life as a leader of mankind. Edison's personal belief is an inexhaustible spiritual treasure for our future generations! He is humble, approachable and consistent in his work. Edison taught us: As long as we work hard, we can achieve our goals. This is the most precious inheritance he has given us!
Enlightenment
From birth to death, the entire life requires hard work and diligence. I have done my best for the happiness of mankind, and there is nothing to regret! These last words are the best summary of the life of the great inventor Edison. Edison's life was a life of invention, creation, and even more diligence.
Diligence is not an unfamiliar word to us. However, in our daily study life, who can be truly diligent and work tirelessly to achieve their goals? ? Some people say that I have a smart brain and I can solve anything easily. Some people also say that as long as I master effective methods and techniques, diligence or not is not very important. And I think that no matter whether you are smart or whether you have mastered effective methods and techniques, you need to be diligent and hardworking to achieve your goals and ideals.
A reporter once asked Edison: You are a great inventor. The American people admire you very much. They want to know whether your success is due to genius? Edison smiled and said: Genius? Genius does not necessarily lead to success. Genius is just one percent inspiration and ninety-nine percent perspiration. Obviously, Edison wanted to tell people that talent may be important, but diligence and hard work are more important. People live in this world to do something useful to society to reflect their own life value and prove that they are worthy of their time in this world. However, we are only used to seeing the success and glory of others, and seeing the magnificence and wealth of others. Little do we know that behind this success, how much diligence, hard work and sweat have led to today's glory.
Everyone is equal at birth. The reason why some people become successful and contribute to society in the future, while others are destined to remain unknown all their lives and even become a burden to society, is because successful people I understand that if you want to succeed, you must be diligent and hardworking. Introduction to Lawrence
Introduction to Lawrence
Lawrence: Tolerance is a virtue
Introduction D. H． D.H. Lawrence (1885~1930) was the most unique and controversial British writer of the 20th century. Known as one of the greatest figures in the history of British literature. Lawrence was born in Eastwood, Nottinghamshire, to a coal miner father and a primary school teacher. After graduating from high school, Lawrence worked as a clerk and taught before entering Nottingham University College to receive vocational teacher training. Genius is an appropriate word to use to describe Lawrence. The British society at that time paid great attention to a person's origin and upbringing, and the society was still permeated with the Puritan atmosphere since the Victorian era. Lawrence, who grew up in this era, was different. Ford Madox Huefer, the first critic of Lawrence in history, said of him: He is a genius, a genius soaked in lust.
Laurent's first novel "The White Peacock" (The White Peacock.ck) was published in 1911. The autobiographical novel "Sons and Lovers" (S.ns and L.vers, 1913) is the most influential of his early works. In 1912, Lawrence eloped to Italy with Frieda, the wife of a professor at the University of Nottingham, and married her two years later.
After their marriage, the Lawrences lived in England, but during World War I, Frida's German origins and Lauren's new anti-war sentiments strained their relations with the British authorities, and they had to return to Italy. During this period, Lawrence created his two most successful novels, "The Rainbow" (The Rainb.w, 1915) and "Women in Love" (W.menin L.ve, 1921). Both works strongly criticized capitalist industrial civilization. After 1919, due to health reasons, Lawrence continued to travel and visited Ceylon, Australia, Mexico and some countries on the European continent. Using these places as the background, he created "Kangaroo" (Kan, gar., 1923) and "Kangaroo". "The Plumed Serpen" (The plumed Serpen, t, 1926) and other works. After 1926, he lived in Italy most of the time, where he wrote his most controversial novel "Lady Chatterley's Lover" (Lady Chatterley's Lover, 1928). In March 1930, Lawrence died of tuberculosis in the town of Vence in southeastern France. In addition to his novels, Lawrence also made great achievements in the creation of short stories. In addition, he also wrote a large number of poems, reviews, essays, etc. He was a writer with many talents.

Biography
In 1929, one year before Lawrence died, he wrote a letter to his eldest son in London in Vence, France, advising his son to learn tolerance. , and said that it was of great help to his life. The content of the letter is as follows: Dear son: In this letter, I would like to exchange views with you on the issue of tolerance you mentioned. I think whether a person is open-minded and magnanimous? Tolerance is not a trivial matter. It is not only related to one's work and study and even one's own life and health, but also related to the rise and fall of the career.
Tolerance is the temperament of being patient and aboveboard toward those who differ from one's own in opinions, habits, and beliefs.
Opening your mind to new ideas and information is not just to make your personality more attractive. Although tolerance and tact are closely related, tolerance is more difficult to identify than tact. You may not be able to learn every new idea you come across, but you can study it and try to understand it.
