What is nano? What are its advantages?

1. Nano-washing: For example, soap made from nanomolecules Na(OH)2 can be fully dissolved in liquid, which helps to decompose stains on clothes and wash clothes thoroughly!

2. Nano-scalpel: Scientists use nano-scale scalpels to cut surgical wounds with minimal precision and ensure the minimum flow of blood!

3. EPS: Apply nanotechnology to split gasoline molecules into protons in nanometer units to ensure full combustion. The consequence of this application is that gas combustion can completely help improve power, save energy, etc.

A German research institute uses a special non-pollution wear-resistant transparent coating made of nano-silica-based ceramics, which can be applied to glass, plastic and other objects to have anti-fouling, dust-proof, scratch-resistant, wear-resistant, fire-proof and other functions

How to learn in life

During the Han Dynasty, Kuang Heng was very diligent and studious when he was young. Because his family was very poor, he had to do a lot of work during the day to earn money. Only at night could he sit down and read in peace. However, he couldn't afford candles, and he couldn't read when it got dark. Kuang Heng was heartbroken for this wasted time, and felt very painful inside. His neighbor's family was very wealthy, and candles were lit in several rooms at night to light up the house. One day, Kuang Heng plucked up the courage and said to his neighbor: "I want to study at night, but I can't afford a candle. Can I borrow an inch of your house?" The neighbor always looked down on people who were poorer than his family, so he made a vicious mockery. Said: "Since you are too poor to buy a candle, why should you read?" Kuang Heng was very angry after hearing this, but he was more determined to read well. Kuang Heng returned home and quietly cut a small hole in the wall. The neighbor's candlelight came through the hole. With this faint light, he began to read books eagerly, and gradually read all the books at home. After reading these books, Kuang Heng felt that the knowledge he had mastered was far from enough, and his desire to continue reading more books became more urgent. There is a wealthy family nearby with many books. One day, Kuang Heng packed up his clothes and appeared in front of a wealthy family. He said to the master: "Please take me in. I will work for your family for free. Just let me read all the books in your family." The master was moved by his spirit and agreed to his request to borrow books. . Kuang Heng studied diligently in this way. Later he became the prime minister of Emperor Yuan of Han Dynasty and became a famous scholar in the Western Han Dynasty. [Word at the end of the chapter] This fable describes two things Kuang Heng did when he was a boy: one was cutting through walls to steal money, and the other was borrowing books to study hard. He praised Kuang Heng for his courage to overcome difficult conditions and his diligent study spirit; he set a good example for us to study hard immediately. ———————————————————————————— Ba Jin’s Reading Method The famous writer Ba Jin’s reading method is very strange, because he did it without books. carried out. It is indeed a wonder in the world to study without books. What is going on? Ba Jin said: "The second time I was hospitalized, I took a nap for less than an hour every day, then got out of bed and sat on the small sofa, waiting for the nurse to come. I came to take my temperature at 1 o'clock. I sat motionless, but my mind refused to rest. It seemed that it wanted to remember some books and works I had read in the past. Before the decline, keep some good things." It turns out that his way of reading is to sit quietly and recall the books he has read. This has many advantages: (1) It is not restricted by conditions and can make full use of time. Ba Jin cited two examples: One was during the Soviet Patriotic War, when Leningrad was besieged by the German army for a long time, a girl wrote in her diary "such and such type, "Anna Karenina"" and the like sentence. There was no electricity or candles at that time, and the entire city was under blackout. She could not read, but sat quietly in the dark and recalled the plot of the book. Tolstoy's novels helped her survive those terrifying nights. Another example is his own personal experience during the decade of civil unrest. He said: "During the 'Cultural Revolution', if the rebels had allowed me to write a diary and allowed me to write a diary according to my own wishes, my diary would have been filled with book titles. People would be surprised: there was a seal in my study, and The lock has been closed for ten years. Where can I find those books to read? They forget that there is a big warehouse in the human mind, which stores things that others cannot take away. "These two examples show that everything is not normal. You can "read" under any reading conditions. (2) Review the past and learn the new. Through recollection, take out the books you have read in the past and chew them bit by bit, just like a cow ruminating, which can further digest and absorb. Every time you recall, you will have new understanding, new knowledge, and new gains. (3) Be able to continuously draw spiritual strength from the books you have read.

Ba Jin said: "I am fighting against illness now and get encouragement from various works... Even if I don't have the energy to read new works while I am ill, the accumulation of spiritual wealth in the past is enough for the rest of my limited life." Until death, people need light and heat." ______________________----------------------------- Gu Yanwu supervised his reading "Every man is responsible for the rise and fall of the world. "This well-known saying was first put forward by Gu Yanwu, a patriotic thinker and famous scholar in the late Ming and early Qing Dynasties. Gu Yanwu has been diligent in studying since childhood. He was enlightened at the age of 6 and started reading history books and literary masterpieces at the age of 10. When he was 11 years old, his grandfather Liyuan Gong asked him to finish reading "Zi Zhi Tong Jian" and warned: "Nowadays, some people want to save trouble and think that everything is settled after just browsing a book like "Compendium" , I think this is not worthwhile." These words made Gu Yanwu realize that studying and learning is an honest thing and must be treated seriously and faithfully. Gu Yanwu studied diligently, and he adopted the measure of "self-supervision of reading": first, he set himself a number of volumes that he must read every day; second, he restricted himself to copying the books he read after reading every day. After he finished reading "Zi Zhi Tong Jian", one book became two books; again, he required himself to take notes and write down his experiences every time he read a book. Some of his reading notes were later compiled into the famous "Rizhilu"; finally, every spring and autumn, he would review the books he had read in the first half of the year, reciting them silently and inviting others to read them aloud, and discovered the differences. Check immediately. He stipulated that he should review 200 pages of classes in this way every day. He would never finish the review and never take a break. -------------------------------------------------- ----How did Chairman Mao study? Special Hobbies: Chairman Mao has been very busy for decades, but he always finds time, even every second, to read and study. His former residence in Zhongnanhai is simply filled with books. There are books everywhere on the bookshelves in the bedroom, on the office desk, dining table, and coffee table. Except for the place where one person is lying on the bed, all of them are occupied by books. In order to study, Chairman Mao used all available time. During the few minutes of physical activity before swimming, I sometimes read a few poems by famous people. After swimming up, I didn't bother to rest, so I picked up the book again. He never wastes even a few minutes on the toilet. A reprint of "Selected Works of Zhaoming" by Chunxi of the Song Dynasty and some other books and periodicals were made by using this time to read a little bit today and a little bit tomorrow, intermittently. When Chairman Mao went out to hold meetings or inspect work, he often wrote in the box. He ignored the vibrations and bumps of the train on the way. He always held a magnifying glass in one hand and pressed the page of the book with the other, reading without stopping. When I go abroad, just like in Beijing, there are books placed on the bed, on the office desk, on the coffee table, and on the dining table, and I read them whenever I have free time. Although Chairman Mao was seriously ill in his later years, he still continued to read. He re-read a set of hardcover "The Complete Works of Lu Xun" that was brought to Beijing from Yan'an and published before liberation, as well as many other books and periodicals. Once, Chairman Mao's fever reached over 39 degrees, and the doctor did not allow him to read. He said sadly, I have loved reading all my life, but now you don't let me read, and you tell me to lie here and eat and sleep all day long. You know how uncomfortable I am! The staff had no choice but to take the books away again. Putting it next to him, he smiled happily. Study seriously and read over and over again. Chairman Mao has always been opposed to the kind of reading method that only seeks to read books quickly and not to be effective. When he read the complete collection of Han Changli's poems and essays, except for a few chapters, he carefully considered and studied every chapter, from vocabulary, sentence reading, chapters to the meaning of the full text, not letting go of any aspect. Through repeated reading and chanting, he can recite most of the poems in Hanji fluently. He had read "Journey to the West", "A Dream of Red Mansions", "Water Margin", "Romance of the Three Kingdoms" and other novels since he was in elementary school, and read them again in the 1960s. He has seen more than ten different versions of "Dream of Red Mansions". A "Selected Works of Zhaoming" was read when he was in school. He read it in the 1950s and 10s, read it in the 1960s, and read it several times in the 1970s. There are three existing versions of his annotations. He read some books on Marxism-Leninism and philosophy more times. He read "History of the United Communist Party" and Li Da's "Outline of Sociology" ten times each. He has repeatedly studied "The Communist Manifesto", "Das Kapital", "Selected Works of Lenin", etc. Many chapters and paragraphs are also annotated and underlined. For decades, every time Chairman Mao read a book or article, he would mark various symbols such as circles, bars, and dots in important places, and write many comments in the headers and blank spaces. Some even read books and articles%

Life requires learning composition

Is this life? We have to be in a hurry. A lifetime? So what should we do in these hurried days? How can we live a life without regrets? What do we need? That’s right, that’s learning, learning, and learning. Learning is an everlasting topic from ancient times to the present. Without the understanding of learning, there will be no direction to lead life. Without the motivation to learn, all that is left is ignorance and confusion, so life needs learning, and we need to get the flash of life from learning.

Think about China's journey from primitive society to the present era of advanced science and technology, from scratch, from poverty and backwardness to a prosperous country and a strong people. What kind of power has allowed the motherland to remain standing for five thousand years? That's right, people are constantly learning, and only with the knowledge gained through learning can they create and develop. The development of a country cannot be separated from the people, but people's cognition cannot be separated from learning. This is a truth. Learning is like the ladder of life. It is a step-by-step process. We never stop climbing. There have been many celebrities with lofty ideals who knew how to learn and master knowledge, which led them to achieve amazing achievements. Henry Ford, the famous American car manufacturer, once said: When a person stops learning, he is old! Whether you are 30 years old or 80 years old. Only by never stopping learning can you stay young. The most important thing in life is to stay young mentally. So study hard to stay young! Learning is an essential spice in life. When you feel bored and your future is bleak, you might as well try this spice and let it help you gain more knowledge and let you realize that learning makes you enjoy it. How wonderful it feels. The Analects of Confucius says: It is not a pleasure to learn and practice it from time to time. Only by learning can you feel happy and fulfilled in your life. There is such a celebrity, he is a household name. He is the famous American inventor "Edison". He grew up in a poor family and dropped out of elementary school after only three months. During class, his mother was often called to school to talk to the teacher. This was because Edison often asked questions that the teacher thought were strange. The teacher thought he He is an imbecile child. So my mother decided to teach Al herself. Edison has been curious about many things since he was a child, and he likes to experiment until he understands the truth. He was immersed in his hot scientific experiments throughout his life, and he obtained 1,093 patents. It is his diligent self-study, diligent study of inventions, and good thinking attitude that can transform him from an imbecile in the eyes of others to the "king of inventions" he is today. He once said: Genius is one percent inspiration and ninety-nine percent perspiration. Yes, 99% of this sweat is his continuous learning process. His learning process was not only filled with sweat and joy, but also resulted in such amazing achievements. This was Edison's life. It can be said that his life was spent in scientific experiments, and his life was spent studying and researching. Life without knowledge is terrible, and an era without learning is ignorant, so let us add the wings of knowledge to life, study to change our destiny, study to make the country rich and the people strong. Let you shoulder the mission of learning and create greater glory. There is no progress without learning, and there is no development without progress. Life requires learning and continuous learning. It takes a spark to start a prairie fire again.
