Of all the things about Cuba, one person often pops out of my memory, which makes me unforgettable.
When the Spanish-American War broke out, the President of the United States must immediately get in touch with the Cuban rebel leader Garcia. Garcia is in the mountains of Cuba, no one knows his exact location, and no mail or telegram can reach him. US President McGinley must get his cooperation as soon as possible.
What should we do?
Someone said to the president, "If anyone can find Garcia, it's Tam."
So the president called Tam and gave him a letter to Garcia. As for the man named Tam, how to get the letter, wrap it in oil paper, seal it and hide it on his chest; How to reach Cuba by boat for four days, then walk through this dangerous island country for three weeks, and finally deliver the letter to Garcia-these details are not what I want to say. I want to emphasize the following points:
The president of the United States handed a letter from Garcia to Tam; After receiving the letter, Tan didn't ask, "Where is he?"
A story about loneliness and persistence
Small stones in the forest bear the flood peak of heaven and earth alone, and believe in eternity in a narrow territory. However, the vast accidents in life constantly leave us no choice, so we started a wandering journey without tomorrow, gave up the growth on the road and witnessed the changes in the world. It turns out that everyone is born lonely. Fragmentation can't reconstruct the psychological deficiency, and change can't come to the perfection of dreams. In this way, in the endless waters of Qianshan, where time passes like an hourglass, it keeps walking, getting lost and out of consciousness.
Everyone has spent his whole life perfecting rich family, love and friendship, and detouring in the sermon of missing, but there is never a clear standard and answer. Childhood stones have been wet in drawers for many years. What is broken is our life, just like the psychic jade in the red chamber. The vicissitude of the surrounding changes, and dust returns to dust.
In the illusory and hopeless expectation, there is no way out, and grasping the past that I want to return to is just a lonely attachment. No dream can last a lifetime, and no place is the home before leaving. Beyond the noise of the world, in one's inner senses, it is bound to be like the advice of the sheep people in Murakami's Dance-keep stepping on your own dance steps, no matter how absurd and desperate, dance well, don't pursue its meaning, and then the stiff things will loosen one by one. Once you stop, the things you connect in life will be.
Whether you go home or go to a brighter place, you must be in a dark place, you must be walking in a dark cotton field, you must be walking in the hometown of dark clouds, and when you go out, you are in the dark.
A continuous story
In ancient times, there was a businessman. One day, he went out for business. He rode a mare and went to the desert far away. Because he has been out for a long time, he needs some requirements. So he came behind the mare, ready to take action. But the mare didn't listen and went straight ahead. If he doesn't follow the mare every time, the mare will never reach it. He tried several times, but it was always impossible. Just when he was disappointed, a beautiful woman came. The beautiful woman is very thirsty. She is very eager for the businessman. Give me some water to drink. I can give you anything. The businessman said, all right. So the merchant handed the water to the beauty. After drinking the water, the beauty said to the businessman, do you have any requirements? The businessman said, can you help me lead this horse?
Thomas Alva Edison is a world-famous American electrician and inventor. In addition to his inventions and contributions in phonograph, electric light, telephone, telegraph and film, he also has many famous creations and opinions in mining, construction and chemical industry. Edison had about 2,000 inventions in his life, which made great contributions to the progress of human civilization.
Edison was born in1February, 847 1 1, 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. When Edison was 7 years old, his father lost money in the tile business and his family moved to Grady Otterborg in the northern suburb of Huron, Michigan. Shortly after moving here, Edison suffered from scarlet fever and was ill for a long time. It is believed that this disease is the cause of his deafness. Edison went to school at the age of 8, but after only three months of study, he was dismissed as an "imbecile" by the teacher and kicked out of school. Since then, his mother has been his "mentor". Because of his mother's good educational methods, he took a keen interest in reading. He not only reads widely, but also reads all kinds of books. At the age of eight, he read the works of Shakespeare and Dickens, the most important playwrights in the English Renaissance, and many important historical books. By the age of nine, he could quickly read difficult books, such as Parker's philosophy of nature and experiment. 10 years old, he loved chemistry. At the age of 1 1, he experimented with his first telegram. In order to make money to buy chemicals and equipment, he began to work. At the age of 12, he got a job selling newspapers on the train, commuting between Port Huron and Detroit, Michigan. While selling newspapers, he also deals in fruits and vegetables. Whenever he is free, he goes to the library to read books. He bought an old printing press and began to publish his own weekly newspaper, The Herald. The first issue of this weekly is printed on the train. With the money he earned, he set up a chemistry laboratory on the baggage car. Unfortunately, once a chemical caught fire, he and his equipment were thrown out of the car. Another time, when Edison tried to board a freight train, a conductor grabbed him by the ear and helped him get on the train. This action led to Edison's lifelong deafness.
1862 In August, Edison rescued a dying boy on the train track with fearless heroism. The child's father is grateful for this, but he is willing to teach him telegraph technology because he has no money to reward him. Since then, Edison has forged an indissoluble bond with this mysterious new electric world and embarked on a scientific journey.
1863, Edison worked as a telecom operator in Stratford Hub Station, the main railway line. From 1864 to 1867, I worked as a telegraph operator in all parts of the central and western regions and lived a life similar to wandering. Footprints include Stratford, Adrian, fort wayne, Indianapolis, Cincinnati, Nashville, Tennessee, Memphis, Louisville and Huron.
1868, Edison came to Boston as a telegraph operator. In the same year, he obtained the first invention patent. This is a device for automatically recording votes. Edison thought that this device could speed up the work of Congress and would be very popular. However, a member of Congress told him that they had no intention to speed up the agenda, and sometimes voting was slow because of political needs. From then on, Edison decided never to make any inventions that people didn't need.
At the beginning of June 1869, he came to new york to look for a job. While he was waiting for a summons in the broker's office, a telegram broke down. Edison was the only person there who could repair the telegraph, so he got a better job than he expected. On June+10, 65438, he and Pop established "Pop-Edison Company", which specializes in scientific instruments for electrical engineering. Here, he invented "Edison Universal Printing Machine". He dedicated this printing machine to the manager of a big company on Wall Street. He wanted to charge 5000 dollars, but he didn't have the courage to say it. So he asked the manager to give a price, and the manager gave 40 thousand yuan.
Edison used the money to build a factory in Ward Street, Newark, New Jersey, which specializes in manufacturing all kinds of motors. He worked all night. He trained many capable assistants, and at the same time, he happened to meet diligent Mary, his first bride in the future. In Newark, he invented wax paper and mimeograph. From 1872 to 1875, Edison invented the two-pole and four-pole telegraph successively, and helped others to make the world's first English typewriter.
1in the spring of 876, Edison moved to Menlo Park, New Jersey again. He built the first "invention factory" here, which "marked the beginning of collective research". 1877, Edison improved the telephone invented by Bell and put it into practical use. He also invented the phonograph, one of his favorite projects. Telephone and telegraph "are a revolution to expand human sensory functions"; The phonograph is one of the three great inventions that have changed people's lives. "From the imagination of the invention, this is his extremely significant invention achievement." At this time, people called him "the magician of Monroe Park".
When Edison invented the phonograph, after numerous failures, he finally made a breakthrough in the study of electric lights. 1879, 10 year1October 22nd, Edison lit the first electric lamp with wide practical value. In order to prolong the life of the filament, he tried more than 6,000 kinds of fiber materials and found a new luminous body-Japanese bamboo filament, which can last for more than 1000 hours and achieve the purpose of durability. To some extent, this invention is the pinnacle of Edison's life. Then, he created a power supply system, which made the distant lights distribute electricity from the central power station, which was a great technical achievement.
His first discovery in pure science appeared in 1883. When testing the electric lamp, he observed what he called the Edison effect: in a lighted bulb, charge travels from the hot filament through space to the cold plate. Edison applied for a patent for this discovery in 1884, but did not study it further. Scientists nearby developed the electronic industry, especially radio and television, by using the Edison effect.
Edison tried to do for his eyes what the phonograph did for his ears, and the movie camera was born here. Using a piece of celluloid film newly invented by George Heasman, he took a series of photos and projected them on the curtain quickly and continuously, creating the illusion of movement. He experimented with movies for the first time in the laboratories of 1889 and 189 1. 1903, his company produced the first feature film great train robbery. Edison did a lot of work for the establishment and standardization of the film industry.
After Edison moved his laboratory to West Orange in 1887, he founded many commercial companies, manufactured products and popularized his various inventions. These companies later merged into Edison General Electric Company, which was later called General Electric Company. Since then, his interests have turned to fluorescence, ore mashers, magnetic separation of iron, storage batteries and railway signaling devices.
During World War I, he developed a torpedo device, a flamethrower and an underwater periscope.
1929 10 2 1 On the occasion of the 50th anniversary of the invention of electric light, people held a grand celebration for Edison, and famous scientists such as Einstein of Germany and Madame Curie of France congratulated him one after another. Unfortunately, at this celebration, Edison suddenly fainted because of excessive excitement during his defense. Since then, his health has gone from bad to worse 193 1 year1October 18 The scientist who made great contributions to mankind died of illness at the age of 84.
Edison's cultural level is extremely low, but his contribution to mankind is so great. What is the secret here? In addition to curiosity, he also has an instinct to experiment by himself, that is, he has unlimited energy and courage to work hard beyond ordinary people. When someone called Edison a "genius", he explained: "Genius is one percent inspiration and ninety-nine percent perspiration." He organized many people of different professions in the "invention factory", including more than 65,438+000 scientists, engineers, technicians and workers. Many of Edison's great inventions were achieved by collective strength. His achievements are mainly attributed to his diligence, creativity and collective strength. In addition, his wife also played a very important role.
