Reflection 1 19 the great moment when science changed human life.

1 19 Great Examples of Science Changing Human Life presents great examples of 1 19 science changing human life in the world since the 20th century. Let's share our views on the great example of 1 19 science changing human life. Let's have a look!

1 19 the great moment when science changed human life. I saw 1 this summer vacation. It was very fulfilling and interesting. What I found most interesting was reading a super interesting book-119 great moments when science changed human life on a global scale since the 20th century.

This book made me realize the greatness of science. With the progress of science, inventions are more and more extensive, and science makes many things incredible! Yuan Longping, the father of hybrid rice, invented hybrid rice to fill the hungry people at that time; Edison, a great scientist, had a firm belief and invented electric light again and again, bringing people light; The invention of X-ray makes us remember Roentgen forever! These inventions are of great significance to the times, and they are all inventions that open a better life for mankind! Scientists' contribution to medicine is even more amazing! One of the heart transplants, when I read this article, I was almost surprised from ear to ear. The first successful human heart transplant happened in 1962 65438+ early February. The 53-year-old grocer had a heart attack and was dying. When the transplanted heart beat in his chest again, everyone was ecstatic! It's like coming back to life! Can make a family full of more lasting happiness and happiness! The bold innovation of science has brought endless benefits to people!

With the rapid development of science and the acceleration of change, our lives have gradually become different. Our life is inseparable from science, and of course scientific inventions also come from life! Only by loving life enough can we invent something beneficial to life. When scientists invented the air conditioner and refrigerator, the hot summer became cool; When scientists invented washing machines, flushing toilets and microwave ovens, boring life became rhythmic; When scientists invented cars, highways and airplanes, difficult travel became efficient; When scientists invented computers, QQ and telephone, ancient communication became carefree. These all come from life, convenient life!

Reading this book, let me increase a lot of knowledge, let me understand a lot of truth, and let me respect scientists! If it weren't for their persistence in science and things, and their belief that science can change mankind, how could there be so many inventions? You know, the birth of everything bears the great efforts of inventors. They never let go of every experiment, endured every failure and improved every deficiency, which made today's extraordinary! This also tells us that only with firm belief and repeated experiments can scientific and technological innovation develop.

This book tells us that there is nothing unexpected, only something impossible. As long as we pay attention to observation and think carefully, maybe miracles will happen around us! Science has brought us many changes. We should study hard and make greater contributions to mankind!

The great moment when science changed human life. I accidentally picked up this book, turned over a few pages, and I couldn't put it down anymore. The book 1 19, edited by Lu Yongxiang, tells me about the 1 19 miracle created by science in the 20th century, and 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.

The great moment when science changed human life. I read the book "The Great Moment of Science Changing Human Life" these days 1 19. This is a book about the great inventions of science and technology. Exquisite and humorous pictures and words show us the great inventions of the 20th century (2 1 century).

I think these great inventions were conceived in great dreams of scientists before they were born. Ideals and dreams are the sun of life. Everyone has a dream, the sun is shining upward. I also have a dream.

My dream is to be a painter and paint a colorful world, a beautiful campus and a rich life with a brush. I hope my painting can fly with my dream, and one day the world in the painting will really come true! I will be very excited at that time, just like I just laughed from my sleep at the moment!

I want to draw such a blueprint with a thriving scene on it. The people of the country are safe and well-fed. No thieves, no robbers, everyone is very happy and happy. The world is peaceful and has made progress. Our science and technology are developing rapidly. Every family has a helicopter, and there is a convenient traffic track in the air. Smart home appliances can have anything with a wave of their hands. Scientists have also invented a cloud eliminator and a rain machine, which can rain or shine at any time. The development of science and technology has also improved the speed of agricultural production. Cabbage can grow to 1.5 meters underground and be harvested every two days. Tomatoes can grow as big as pumpkins, and they can be picked in just one day ... so the farm becomes an agricultural factory, because it grows as fast as the factory. In this way, we can eat fresh fruits and vegetables every day, and the physical quality of human beings is getting stronger and stronger. If there is an alien invasion, we will also be strong in the universe. ...

This is a picture in my mind, which came to my mind after watching 1 19 the great moment when science changed human life. Through reading, I feel that science has really brought many changes to our lives and the world. Science is endless, only unexpected, nothing impossible! Take off, dream! I think I will study hard and make greater contributions to mankind.

This is my Chinese dream.

The great moment when science changed human life. After reading 4, science is great. It has changed many difficult living environments and made our life more comfortable. -inscription

1 19 The Great Moment of Science Changing Human Life lists 1 19 inventions that changed our living environment, including washing machines, refrigerators, air conditioners and so on. There are also the suture technology of severed fingers and X-rays used in medical operations ... which greatly guarantee our living environment and health and the future development of science and technology.

The most unforgettable article is the first trip around the world. It happened in April, 1924. Four planes formed a fleet and set off for the other side of the world. Four planes set sail from Seattle, USA. On the way, Boston and Seattle broke down in the English Channel and Alaska respectively, and the task of traveling around the world was handed over to Chicago and New Orleans.

They look dusty, but their hearts are still full of vitality. Finally, after a flight of 176 days, in this 176 days, they landed 57 times and traveled 44340 kilometers, and finally successfully returned to Seattle, completing the first round-the-world tour of mankind! The success of this round-the-world trip has made outstanding contributions to promoting the marketization of aviation technology in the world science and technology field.

Aren't many scientists trying their best to improve our lives? For example, Grandpa Yuan Longping invented super hybrid rice, saved 60% of the world's population with 20% of the fields, but never had a set of suitable clothes; Madame Curie extracted 0 from two tons of heavy metals. 2 kilograms of radioactive radium, won the Nobel Prize, and treated people with humility and courtesy as always.

The Wright brothers invented the plane and made great contributions to industry, war, transportation and other fields ... they brought great convenience to our lives, but they were not known. Let's remember their names forever.

Come on, let's change life with science and change the world with knowledge! Science is the strongest armed force, and knowledge is the highest guarantee of life!

1 19 the great moment when science changed human life; Every student has his own different dreams. I have many dreams, too. For example, you can sit in a spaceship like Armstrong, the first man on the moon, fly to mysterious outer space and explore the mysteries of the universe that humans have never heard of or seen before; I want to create my own computer kingdom like Jobs in the near future, and develop more incredible and inseparable technology products than "Apple" products; I dream that I can develop the world's top weapons, and a magical chemical substance will happen over the territory of China, making it turn into a huge protective net when necessary, and keep any nuclear bombs and long-range missiles launched by foreign enemies who may go to war against us out of our airspace, so that the enemy will be defeated without fighting; I also want to invent a fast learning chip. Once it is connected with our human brain waves, it will make you learn the most advanced science, technology and knowledge in the world and make China the largest power in the world.

After reading the book 1 19, which was edited by Lu Yongxiang, I think these dreams will come true. This book introduces us to the greatest scientific discoveries and technological inventions in the world since the 20th century in the form of words and pictures, and tells us that it is the rapid development of science and technology that has promoted the development of human society and economic prosperity.

These scientific inventions, creations and technological innovations in the book pay attention to the basic necessities of life of human beings, as Larry Page, CEO of Google in the United States, said in a speech this year-"I believe that people in the future will think that our life today is incredible, just as we look back on the past today." Just as the ancients who invented the "Four Great Inventions" would never have thought that their descendants could launch the first meteorological satellite in 5000 years, watch the weather in the clouds, fly the Apollo spacecraft, cross the atmosphere from the upper reaches of the earth and finally land on the moon. Today's parents probably can't imagine how we will use the magical power of science and technology to bring more creative great inventions and discoveries to mankind in the future.

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.

This book makes me realize that knowledge is power and technology changes the world; This book also makes me know a truth more clearly: dreams need to be persisted! I will study harder from now on, constantly cultivate my spirit of seeking knowledge and exploring, overcome my shortcomings and hone myself. Try hard to write every word, carefully master the learning content every day, read more books, prepare for every exam, and do more social practice ... Start from bit by bit and be down-to-earth, because only in this way can we lay a good foundation for realizing our dreams and better building our prosperous and powerful China!

The realization of the "Chinese dream" has us!
