After reading a famous book, I believe you must have a lot to share. Let's write a comment and record your gains and feelings. But what are the requirements for reading? The following is my collection of 1 19 essays on the great moment when science changed human life (five selected essays). Welcome to read, I hope you will like it.
In the summer vacation, I read the book 1 19, which was edited by Honda. I know that science and technology have greatly helped the progress of human life, which has benefited me a lot.
This book mainly talks about the inventions and discoveries of all scientists since the 20th century, as well as the time, energy and brain power spent. After many failures, these inventions and discoveries condensed the essence of scientists, changed our world and our life at the same time, and made me understand the importance of science and technology. At the same time, I would like to thank the scientists who invented these good things, who gave us a bright future and infinite happiness in human life.
I remember that in the past, people at that time, despite their unremitting efforts, could not fill their stomachs with harvested food. But after 1973, grandpa Yuan Longping and his assistants made unremitting efforts, and finally successfully planted giant rice in Changsha for the first time, which successfully solved the problem of food and clothing for human beings all over the world and brought warmth and happiness.
I still remember another great moment, that is, the British chemist Hopkins solved the mystery of intentional diseases caused by the lack of this trace substance for the first time, and created a road to synthesize vitamins. Therefore, vitamins have become an indispensable substance for people to maintain their lives. Scientists separated vitamin A from soluble vitamins, and then extracted vitamins B, C and D one after another. After years of in-depth research on vitamins, scientists gradually figured out vitamins, which not only basically solved the problem of prevention and treatment of vitamin deficiency, but also deepened the study of human metabolism.
The application speed of science and technology is becoming faster and faster, and more and more. It has accomplished many things that originally needed human beings to do, even faster and better. However, these are achieved through the continuous learning and accumulation of knowledge, through the hard and persistent efforts of scientists, and through the continuous efforts and persistence of generation after generation.
Facing the dawn of the new century, we are willing to make every effort to further develop science and technology, so as to make the human world take a step towards success, spread scientific knowledge and carry forward scientific spirit. The realization of the "Chinese dream" has us!
The book 1 19, edited by * * *, made me understand the 1 19 miracle created by science in the twentieth century, and learned that science can be seen everywhere around us.
After reading this book, it seems that even the world is different: when eating seedless watermelon, I will think of Uncle Huang Changxian who cultivated seedless watermelon; When you are comfortably lying on the sofa watching TV, you will think of Baird, the British inventor who invented TV; When you write with a ballpoint pen, the name of Hungarian Radislav Biro pops up in your mind.
Are they geniuses? This question is hard to deny. Do these scientific giants find problems because they are geniuses? Not exactly. Every story shows that these scientific giants can find problems and reasonably explain or apply this discovery to real life through careful observation, serious thinking and repeated experiments.
I also learned from them and found some small discoveries in my life: on rainy days, there is water in the canopy, and sunlight shines on the wall through the water, leaving a vague light spot. In fact, the principle of focusing with a magnifying glass is the same. When sunlight passes through water, it is refracted by water and focused together, resulting in this spot; Traveling to Inner Mongolia by car, the potato chip packaging bag bulges like an airbag and bursts when pressed. Because of the high altitude and low air pressure in Inner Mongolia, the air pressure in the potato chip packaging bag is higher than that outside, of course, it bulges, and the expansion of mineral water drinks is also the reason. I never paid attention to these small details before reading this book.
This book has a great influence on me and taught me a lot of scientific knowledge. In fact, science is everywhere. Sometimes you feel that you can't see it, not because there is no science, but because you haven't observed it carefully. This book tells me that as long as you observe carefully, you will surely discover the mystery of science.
Detective Conan is my favorite animation of science fiction detective stories, but 1 19 The Great Moment of Science Changing Human Life is my favorite scientific knowledge book. I have been reading carefully recently, and I am deeply touched. I was surprised to find that science is so fascinating, and the world we live in is full of surprises and sighs.
The development of today's society is inseparable from science and technology, which is the first driving force of production development. Therefore, we young people must cherish today's opportunity, study hard, devote ourselves to the ocean of science and technology, enjoy the milk of science and technology, understand the magical science and technology and the great creativity of human beings, and thus stimulate our love for knowledge, especially science and technology. Lay a solid foundation for future work and social progress.
The future of teenagers is the future of a country and the master of the future. If a teenager is weak, the country will be weak, and if a teenager is strong, the country will be strong. It is an urgent task for teenagers to arm themselves with knowledge and develop themselves with science and technology. "Wen can govern the country and protect the country." In China in peacetime, cultural knowledge should be in the forefront, and now "martial arts" has changed. Believe it or not, the explosion of China's first atomic bomb shocked the whole world. This explosion has condensed the hard work and sweat of many Chinese sons and daughters, the wisdom of many talents and the high-end scientific and technological content; This bombing not only made foreign powers dare not covet China any more, but went hand in hand with China politically and economically, sharing weal and woe. This is the magic and power of science and technology, and it is also the great creativity of mankind.
The world of technology is rich and colorful. The invention of color film keeps our bright smiles and beautiful images in your sight forever; The appearance of the first automobile production line allows us to sit comfortably on the sofa and visit Wan Li Road every day to enjoy the natural scenery. The output of seedless watermelon makes people feast their eyes, saving the trouble of spitting melon seeds; The birth of vitamins and penicillin ... made the tree of life evergreen and shortened the life span of bacteria ... It is precisely because of the rapid development of science and technology that we have a happy and harmonious life today.
The book 1 19, the great moment when science changed human life, brought together great inventions of science and technology, condensed the essence of human cultural food, practiced social core values, and constructed the great rejuvenation of mankind. I want to be inspirational, work hard and strive for the rise of the Chinese nation.
This summer vacation, I used my spare time to read the book 1 19 the great moment when science changed human life. This book shows the great moment that science has changed human life around the world since the 20th century. Here it is. I find science so fascinating that the world we live in is full of surprises and sighs. For example, the popular artificial cotton; Vitamins that can make the tree of life evergreen; The internet that connects the world together; Turing machine, the mother of calculators; Hybrid rice that keeps the world away from hunger; Everyone loves Penguin Tencent QQ…… ... Next, I will tell you a few things that interest me:
Laser, laser is called "the fastest knife", "the most accurate ruler" and "the brightest light". It is a great invention of mankind after atomic energy, computer and semiconductor in the 20th century. The brightness of laser is billions of times higher than that of the sun. It was Einstein who first proposed laser, and he put forward the concept of "stimulated radiation". The first laser beam ever obtained by mankind was in May 1960. In May 15, the scientist Mayman of Hughes Laboratory in California announced that he had obtained a laser with a wavelength of 0.6943 micron. On July 7th of the same year, Hughes announced in new york that the first working laser was born! After a lapse of one year, that is, 196 1 August, China's first laser, the ruby laser with small ball illumination, was also born in Changchun Institute of Optics and Mechanics, Chinese Academy of Sciences. The designer Professor Wang Zhijiang was called "the father of China laser". 1975, the first laser rangefinder in China was successfully developed. 1980 The medical high-power laser gasification tumor device pioneered in China provides a new means for treating cancer. 1994, the world's first stereo video karaoke laser disc came out in China. At present, laser is widely used, which can be said to have penetrated into various fields of production, national defense, scientific research, medical care and life.
This book embodies the wisdom of human civilization and progress; This book helps us to know more about ourselves and the world we live in. This book tells us that science is everywhere.
Do you know who invented air conditioning? Do you know who is the "ancestor" of computers? 1 19 The Great Moment of Science Changing Life tells the origin of many things that we are used to now. Today, I'm going to tell you a part of this book-the origin of computers.
The earliest "ancestor" of computer was mathematician and logic theorist Turing. During World War II, Turing was employed by the communications department of the British Foreign Office. Turing spent two years (it can be said that he didn't eat or drink) and spent/kloc-0.0 million pounds to build the original computer-Turing machine. Turing cracked the enigmatic code used by Germans to transmit information with his own machine, and published an article about computers the following year. 1June 8, 954 Turing died with an apple on his head, at the age of 42. Apple Computer Company commemorates Turing, the great pioneer of artificial intelligence, with the apple he bit as a symbol.
Later, in the 1940s, von Neumann developed a modern computer with more unified functions, more uses and wider applications, and used coding programs to design the computer. Finally, the modern computer was born. It is the moment created by scientists with their years of hard work that has changed human life and led to the rapid development and wide application of modern computers. Now people can't live without it in all aspects of life and work.
Science has changed our way of communication and lifestyle, and let me know that science is endless. Only unexpected things, nothing is impossible! We should cultivate our good habit of loving and learning science from now on, study hard and climb the peak of science forever.
