This is an obvious truth, and many stories tell us this directly. Ancient papermaking and printing, modern electric lights, telephones, computers and the Internet have all brought earth-shaking changes to people's lives and destiny.
Here, let's review the story of Bell's invention of the telephone. Before the invention of the telephone, the main way for people to contact in different places was to send telegrams. However, telegrams can't exchange information in two directions in time, and the procedures are troublesome. Many people have to travel back and forth in order to keep in touch with distant places in time, and at the same time they have to pay a lot of money. Therefore, people began to explore a communication method that can directly transmit human voice.
Alexander bell, an American, systematically studied human voice, vocalization mechanism and sound wave vibration principle. In the process of designing hearing AIDS for the deaf, he found that the spiral coil made noise at the moment when the current was cut off. This discovery suddenly occurred to Jambers-"Use the strength of current to simulate the change of sound size, so as to transmit sound with current." From then on, Bell and his assistant Watson began the arduous process of designing telephones. 1On June 2, 875, Bell and Watson were working on the final design and improvement of the model. It's time for the final exam. Watson put his ear to the speaker in another room with closed doors and windows, ready to answer. Bell accidentally spilled sulfuric acid on his leg during the last operation. He cried out in pain, "Mr. Watson, come and help me!" " Unexpectedly, this sentence reached the ears of Mr. Watson, who works in another room, through the telephone in his experiment. This very common sentence, however, became the first voice transmitted by telephone and went down in history.
1876 On March 7th, Bell obtained a patent for telephone invention, and the next year, the first telephone lines set up in Boston and new york were opened. It was also in this year that someone sent news information to the Boston Globe by telephone for the first time, and the era of using public telephones began. Within a year, Bell installed 230 telephones and established Bell Telephone Company, which was the predecessor of AT&T Company. ..
Bell invented the telephone with his knowledge, and directly benefited himself. When he is in pain, he can call someone to help him relieve the pain as soon as possible. Next, he set up a telephone company, and wealth rolled in. At the same time, the invention of the telephone has brought a lot of convenience to mankind and brought many changes to human life and destiny. It can be seen that the power of knowledge is infinite, just like a river, which will flow forever, and can bring changes to almost everyone's life and change the fate of most people.
Let's look at another different story. In ancient Greece, a businessman saw Thales in rags and looking like a beggar in the street and said sarcastically, "Thales, people say you are a knowledgeable philosopher, but what can your knowledge bring you?" Is it gold or bread? You are so shabby now, which proves that knowledge can only bring you poverty! "Thales retorted," I forbid you to use my poverty to belittle the role of knowledge. We'll see. I'll teach you a lesson with facts. "He has rich knowledge of mathematics, astronomy and agriculture, and concluded that there will be a bumper harvest of olives next year, so he rented all the olive oil presses nearby at a low price in advance. The following year, when olives were harvested, he rented an oil press at a high price and made a fortune. The businessman who satirized Thales had to squeeze into the crowd renting oil presses. As soon as Thales saw him, he said, "Noble rich man, see! I used my knowledge to get these oil presses. If I want to get rich, I can get it easily by playing one or two tricks ... but it's not money I'm after. What I need is knowledge. Knowledge is priceless and the greatest strength! "
Knowledge is power, which gives people the power to fight against fate. Not only ordinary healthy people, but also disabled people can accept the baptism of knowledge, benefit from the power of knowledge, and gain the courage to fight against fate with knowledge. Helen Keller was blind, deaf and dumb with a high fever when she was young. Since then, she has fallen into a dark and silent world. However, her life has not passed away. She later became a world-famous writer and educator. In Mark Twain's eyes, there were two great figures in19th century, one was Napoleon and the other was her. It is not the power of God that can make Helen fly between hell and heaven. Besides perseverance, there should be only the spirit of seeking knowledge. That's how she stepped into the light in the dark.
1880 On June 27th, Helen Keller was born in a small town in Alabama, USA. /kloc-at the age of 0/9 months, he became blind and deaf due to high fever caused by sudden scarlet fever, and became a blind, deaf and dumb disabled person. Later, Miss Anne Sullivan, a tutor, taught her to write, point words and write square characters with a pencil. Before 16 years old, she had learned to read Braille and had enough writing and speaking skills before entering Radcliffe College. 1904, she graduated with honors. 1955, she received an honorary degree from Harvard University, becoming the first woman in history to receive this honor. Besides English, she has learned and mastered French, German, Latin and Greek, but she is deaf and blind but can master five languages. Helen's success is called "the greatest achievement in the history of education". She published a monograph 14 all her life. In the past century, my life story has been translated into more than 50 languages and spread all over the world. 19 19, Helen's story was put on the screen by Hollywood and starred by herself. Helen devoted her life to the welfare and education of the blind and won the praise of world public opinion. From 65438 to 0959, the United Nations also launched the "Helen Keller" World Campaign to help deaf children all over the world. Helen died in June 1968 at the age of 87. Her life has set an example for people to fight against fate. Helen Keller International Organization is named after her, aiming at fighting blindness in developing countries. Today, this organization is one of the largest organizations providing help to the blind overseas.
From Anne Sullivan, Helen learned how to know the world and master its knowledge. The light of knowledge lit up Helen's heart and took her out of the darkness. In today's world, knowledge is the most powerful and effective force to change the fate of life, and the desire for knowledge is the best wish of mankind.
Knowledge changes everyone's destiny, not only those famous people, but also everyone around us, including ourselves. No matter whether you were born in a city or a mountain village, everyone has the right to education, and everyone has to go to school, because knowledge is the most important capital in life.
The world is unfair. But the biggest inequality between people is not the difference in wealth, but the difference in knowledge. The disparity of wealth will not have much influence on the communication between people, but the disparity of knowledge is like two completely unfamiliar worlds. The communication gap is deep, even if we are sisters, we are afraid of becoming strangers. Thus, the weight of knowledge in a person's life.
