Technology changes the world

science? What does science mean? What has changed in science and technology? Science and technology, it promotes the progress and development of human life and society, and it is a new world view for more human beings, creating a new era of the era of scientific and technological wisdom. Make a big transition in the era of backwardness and not advanced. It has become a living, bright, bright and progressive world, which makes people tired and relieved, making more miracles come true!

For example, flying, the ancient people see the flying sky as a legend is unknown, there are infinite aspirations and awkwardness for thousands of years in the sky, no one can fly for themselves, but it is science and technology, science and technology. It is the dream of mankind that has been realized for decades, and the outer space that is out of reach is closely connected with people. People used to think of flying, but in the future, on April 12, 1961, the Soviet aviation crew added Galin went to outer space and circled the earth 4,000 kilometers, making people think that the legend that can never be realized becomes reality. His small step is a big step for the development and future of human science. Make the legend cast, and rekindle the fire of wisdom in the human heart!

The success of Feitian has certainly made a big step in the development of human science and technology. However, human beings want to have drugs that can protect life and fight disease. In this way, penicillin, which is regarded as one of the world’s three major inventions, has turned out to make infected patients. The source has been greatly reduced, so that the bacteria have been “killed out”, and many people suffering from infectious diseases have been able to rekindle the light of life. This is also due to the scientific invention, the British bacteriologist Fleming has finally found a magical phenomenon after repeated tedious experiments, and together with more scientists to study the deficiency of penicillin, which gave birth to the world's most widely spread, the most widely used The world's first antibiotic with the best efficacy. If it is not the human brain that invents one thing after another, which is related to human life, for the benefit of mankind, how can this world be as vibrant as it is now!

Human life is closely related to science, and science can benefit mankind. However, not all scientific experiments are smooth and unimpeded. They are not universally popularized and widely used. They also contain the bitterness and hardship of scientific experiments. The pain is also inexplicable.

For example, the famous radioactive object "Radium" is known to everyone, and it is also known that it was invented by Madame Curie. However, everyone does not know that there are endless hardships behind his famous one. He is doing day and day in a simple laboratory. In the experiment, because there are many substances in the scientific chemical that harm the human body, in a certain day of experiments, her husband left him. He was particularly sad and unhappy, but she still insisted on her experiments. In the scientific cause, his physical condition is declining. He has experienced numerous failures and frustrations, and he has wanted to give up, but for science, but for science. He remained persevering, and one day he saw a flash of light flashing in a dimly lit house. It is radium, it is radium, she finally succeeded! She made the world see a scientific miracle! I saw the magic and greatness of science! The charm of human wisdom! Make science a new vane of human life!

There is also the famous "inventor king" Edison. He invented countless inventions in his life and benefited the world. Of course, every invention he has suffered has failed, but he has always insisted on science, and the best known is the electric lamp he invented. In the past, people could only use candle lighting, but because of the spread of electric lights, we saw thousands of lights, bright and flashing. However, under the impact of 999 painful defeats, he used the power of science to strengthen and invent the achievement of benefiting mankind and shocking the world. He said that he was inventing, but rather climbing a world peak. What power is supporting him? It is the magic of science. This is a miracle, a miracle in the history of human science!

Science promotes society, science is a human society full of vitality and wisdom, science, change the world!
