Give two examples of scientists in the development of human civilization

Newton made great contributions not only to mechanics, but also to other aspects In mathematics, he discovered the binomial theorem and founded calculus; In terms of optics, he carried out dispersion experiments with sunlight, proved that white light is composed of monochromatic light, studied the theory of color, and invented the reflecting telescope.

In terms of Newton's contributions, he was a great scientist, and his power and hard work in the process of inventing and discovering these substances are worth learning from.

Ancient: , Zhao Shuang, Zhang Heng, Cai Lun, Zhang Zhongjing, Hua Tuo, Li Shizhen, Song Yingxing, Xu Guangqi Modern: Qian Xuesen, Zhao Zhuan Zhongyao,

Modern: Li Siguang, Zhang Yuzhe.

Geomechanics opens up a new path, the number theory school makes conjectures: Li Siguang and Chen Jingrun jointly make alkali and spread it all over the world, Beijing-Zhangjiakou Railway Exhibition Huazhang: Hou Debang and Zhan Tianyou shocked the world with a seed, and two bombs and one star shook the eight directions: Yuan Longping and Deng Jiaxian reached a new high in modern science and technology, and the Chinese spirit was far famous.

To put it mildly, most of the contributions made by Chinese scientists are in the service of the ancient emperors and.

DAO modern **.

Very little is really used for the population. And according to Joseph Needham's question, there have been very few great scientists in China in modern times. And the ancient ones we'd rather call practical scientists, or labor scientists.

But self-deception or self-confidence is still needed.

Zhang Heng ground motion instrument.

Zu Chongzhi Pi.

In ancient times, there were only a few of them, and there might be a little more in medicine, Sun Simiao, Zhang Zhongjing, Li Shizhen, and so on.

In modern times, at least those Chinese Nobel Prize winners, you can write Tsung-Dao Lee, Chen-Ning Yang, Steven Chu.

Qian Xuesen, Zhao Zhongyao, Yuan Longping, Qian Sanqiang, Qian Xuesen, Deng Jiaxian, Wang Ganchangsi. Zhang Yuzhe.

Yuan Longping, this is recognized', in addition to the scientists during the founding of the People's Republic of China: Qian Sanqiang, Qian Xuesen, Deng Jiaxian, Wang Ganchang and a series of two bomb fathers, they also contributed to world peace!

First of all, when alchemy is pushed, the smelting of metals promotes war, and war promotes the progress of social civilization, there is no doubt.

The second is the four great inventions of China, gunpowder will definitely be used in war; Papermaking and movable type printing facilitated the spread of culture, and for the compass, the most famous of the voyages Columbus discovered North America.

In modern times, the invention of the steam engine made manual work mechanized and promoted the development of industry.

With the birth of the internal combustion engine, automobiles, ships, and airplanes were all possible.

The invention of modern electronics was the first to promote the computer, and the convenience of the E era is well known.

Electric steam engine train light bulb ** aspirin computer . It's too much.

The first industrial revolution, the invention of the steam engine, provided steam power for machines, promoted the development of machine production, and mankind entered the "steam age".

In the second industrial revolution, electricity became the most important power for machines, and was widely used in the field of life, and mankind entered the "electric age".

The third scientific and technological revolution, breakthroughs in the fields of atomic energy, electronic computers, aerospace technology, and bioengineering have vigorously changed the way of human production and life, and human society has entered an information society. Dust branches.

In fact, I think that only 7 is right.,The level of this questioner is very poor.,It's probably a question of learning history that doesn't understand chemistry at all.。

It has nothing to do with chemistry at all, and 2 has nothing to do with physics.

1 There is a process of chemical bleaching in papermaking technology, but this has nothing to do with the history of chemistry.

3 The use of gunpowder is a chemical process, but the invention has nothing to do with chemistry, it is just a simple mixture of several substances, which is a complete physical change.

5. Whether these technologies were first invented and used in China has not yet been determined, and if so, this answer can be chosen.

6. Organic polymer materials, I don't know what this has to do with China.

7. Artificial synthesis of protein, this estimate refers to the artificial synthesis of bovine insulin, only this is the most suitable for the requirements of the topic.

8. Atoms are the content of chemical research, molecules are the content of physical research, and the essence of molecular changes is the internal changes of atoms. Moreover, these two theories were put forward by foreigners, and although the ancient Chinese philosophers had philosophical thinking about the basic composition of matter, none of them had ever developed atoms and molecules, right? Now, if you choose 8, I estimate that in a hundred years, this answer will become quark theory.

Anyway, the ancestors did not name the smallest thing that makes up the substance, and whatever foreigners find is what we choose. Pick 8 is to teach students academic corruption.

If you choose B, the printing and guidelines have nothing to do with chemistry, so 2 and 4 are incorrect, and 1 and 3 are mandatory, so choose B
