1. Science and technology make the nation prosperous, while science and technology make the country strong. To achieve the goal of "two hundred years" and realize the Chinese dream of the great rejuvenation of the Chinese nation, we must adhere to the road of independent innovation with China characteristics, face the forefront of world science and technology, face the main battlefield of the economy, face the major needs of the country, accelerate scientific and technological innovation in various fields, and seize the opportunities of global scientific and technological competition. This is the starting point of our proposal to build a world power in science and technology.
2. Science and technology are great creative activities of human beings. All scientific and technological innovation activities are done by people. Building an innovative talent team with large scale, reasonable structure and excellent quality is the key to building China into a world science and technology power.
Stimulate the innovative vitality and potential of all kinds of talents. We should greatly mobilize and fully respect the creative spirit of the vast number of scientific and technological personnel, encourage them to strive to be promoters and practitioners of innovation, and make planning innovation, promoting innovation and implementing innovation become conscious actions.
3, raincoat 1747, French engineer Franois Fraineau made the world's earliest raincoat. He used latex obtained from rubber wood to dip cloth shoes and jackets in this latex solution, which can play a waterproof role. McIntosh, who works in a rubber factory in Scotland, can't afford rain gear because he lives in poverty. Every rainy day, he can only go to work in the rain.
One day, he accidentally spilled rubber juice on his clothes and couldn't wipe it off, so he had to wear this dirty clothes to go home. It was raining outside, but when McIntosh came home, he was surprised to find that his clothes were not wet at all. He just smeared rubber juice on his clothes. This is the first rubber raincoat in the world.
Zipper was first invented by Chicago mechanic Judson in 189 1 year. In order to relieve the trouble of tying shoelaces every day, Judson invented a zipper which can replace shoelaces. This zipper consists of a row of hooks and a row of buttonholes. Pull an iron slider from bottom to top, and the hook and buttonhole can be fastened one by one.
Judson sent the sample to Columbia Expo on 1893, which was well received and patented. Nowadays, there are more and more kinds of zippers, and their applications are not limited to daily necessities, but also enter the fields of scientific research, medical care, military and so on, and are praised by some as one of the great men in the field of science and technology in the 20th century.
