Read a brief introduction to a scientist in a science book for three years of junior high school and

Eastern Han Dynasty scientist, astronomer, philosopher. The word Pingzi. Nanyang Xi'e, Henan Province (now Shiqiao, Nanzhao County, Henan Province. Zhang Heng pushed ancient Chinese natural science and philosophy to a new level, and his works were collected in the Qing Yan Kejun Institute.

In this carefully condensed book, nearly 100 influential and creative scientists are included. Here, we can see Newton standing on the shoulders of giants, Edison, the inventor, Qian Xuesen, the father of China's aerospace, and Stephen Hawking, a scientific wizard who is paralyzed and still researches, ......The stories of each of them are vivid and interesting to read, but my favorite is Faraday.

Although Faraday is not famous, his love of science is worth learning from each of us. Faraday had a difficult childhood: the son of a poor blacksmith, his father had a small income, was often sick, and had many children, so Faraday could not even eat enough when he was a child, sometimes he could only eat one loaf of bread a week, and because of such a family, he did not even go to elementary school.

Faraday sold newspapers at the age of 12 and worked as a book-bound apprentice at the age of 13, studying himself from the newspapers he sold and the books he printed, until he read the Encyclopædia Britannica. Faraday was particularly interested in chemistry books, so he used his meagre salary to buy chemicals and instruments, conduct various experiments, and record them on waste paper from the printing house to form a manuscript. In this way, when he was 22 years old, he was favored by the great British scientist David at that time, and became David's experimental assistant, and since then he has become a warrior who conquers the fortress of science and has become an excellent scientist.

So I have to learn from Faraday, don't just envy the goodness and advantages of others, and don't work hard.

"One Hundred Stories of Scientists" made me understand that every scientist has obtained his or her own ideals through his own unremitting efforts, and we must also use hard work to achieve our ideals.

From the stories of scientists, we can appreciate a lot of good qualities of scientists, and their research and pursuit of science and technology are very worthy of our learning.

I admired his patriotic enthusiasm and was touched by all the efforts he made for scientific research in China.

I learned that everything must fail first and then succeed.

Edison was different from others in that when he was in elementary school, Edison always asked all kinds of questions to the teachers of various subjects, and in the end, every teacher got impatient and called Edison a "stupid child" and ordered him to drop out of school.

Edison was thirty or forty years old when he invented the daily necessities that shocked the world electric light bulb, not to mention that his invention brought infinite benefits to mankind, let's just say that he experimented more than 1,300 times before he invented the electric light, more than 1,300 times! It's a number that makes the average scientist marvel, but Edison did it! The materials used for filaments are hair silk and spider silk.

More than 1,300 kinds of silk made Eddie's birthday haggard, but when he invented the electric light, he smiled. Edison invented more than 1,300 inventions in his lifetime, so I admire him.

That's the scientist I admire--- Edison.

The story of the scientist Edison, the story of the scientist Edison shocked the world--- Edison In this world, there have been many scientists, some of whom have dedicated their lives to science; Some dare to challenge authority; Some delve into scientific ,..

Edison, the scientist who changed the world--- Edison was a great inventor of the 19th century, he invented many things in his lifetime, and he also had more than 1,000 invention patents in addition to his representative invention of the electric light. Edison was studious and studious as a young man, and was interested in everything.

a. Hou Debang invented the alkali in the combined alkali production method refers to sodium carbovoltarate, so A is wrong;

b. Zhao Zhongqing Peixian and his research team have developed many superconducting materials, so B is correct;

c. Professor Zhang Qinglian accurately determined the new value of the relative atomic mass of indium (in) element, so C is wrong;

D. Liu An did not first discover that there are no neutrons in the nucleus of hydrogen with the help of STM technology, so D is wrong.

Therefore, b
