Who is the famous great scientist?

1, Cai Lun.

Cai Lun (? -12 1) from Guiyang county in the eastern Han dynasty. In the last years of Han Yongping, he entered the palace as a minister. In the second year of Zhanghe (AD 88), Cai Lun was promoted to be a regular servant because of his meritorious service to the Empress Dowager, and Cai Lun also held an official position. Cai Lun summed up people's paper-making experience in the past, innovated the paper-making technology, and finally made "Cai Hou Paper". In the first year of Yuanxing (A.D. 105), it was reported to the court, and Emperor Wu of the Han Dynasty and Emperor Wu of the Han Dynasty ordered the popularization of his papermaking method. In the first year of Jianguang (A.D. 12 1), he committed suicide because of a power struggle.

2. Shen Kuo.

Shen Kuo devoted himself to scientific research all his life, and had profound attainments and outstanding achievements in many disciplines. He is known as "the most outstanding figure in the whole history of science in China". His masterpiece Meng Qian Bi Tan is rich in content and a great achievement of predecessors. It plays an important role in the world cultural history and is called "a milestone in the history of science in China".

3. Zhang heng

Zhang Heng made outstanding contributions to the development of astronomy, mechanical technology and seismology in China, and invented the armillary sphere and seismograph, which was one of the representatives of the theory of armillary sphere in the middle Eastern Han Dynasty.

4. Zu Chongzhi.

Zu Chongzhi studied natural science all his life, mainly contributing to mathematics, astronomical calendar and mechanical manufacturing. On the basis of exploring the accurate method of pi pioneered by Liu Hui, he first calculated the "pi" to the seventh place after the decimal point, that is, between 3. 14 15926 and 3. 14 15927. His "ancestral rate" has made great contributions to mathematical research. It was not until the 6th century A.D./KLOC-that the Arab mathematician Al Cassie broke this record.

5. Einstein

Einstein laid a theoretical foundation for the development of nuclear energy and initiated a new era of modern science and technology, and was recognized as the greatest physicist after Galileo and Newton. 199965438+On February 26th, Einstein was selected as "the great man of the century" by American Time magazine.

6. Newton

In mechanics, Newton expounded the conservation principle of momentum and angular momentum and put forward Newton's law of motion? . In optics, he invented reflecting telescope, and based on the observation that a prism diverges white light into the visible spectrum, he developed the color theory. He also systematically expressed the law of cooling and studied the speed of sound.

In mathematics, Newton and Gottfried Wilhelm Leibniz shared the honor of developing calculus. He also proved the generalized binomial theorem and put forward Newton's method to approximate the zero point of function, which contributed to the study of power series.

In economics, Newton put forward the gold standard.

7. Edison

Edison was the first person in human history to use a large number of production principles and electrical engineering research laboratories to patent inventions, which had a great and far-reaching impact on the world. His invention of the phonograph, movie camera and electric light had a great influence on the world. He had more than 2,000 inventions and 1000 patents in his life.

8. Maxwell

Maxwell is generally regarded as one of the most influential physicists in physics. Without electromagnetism, there would be no modern electrician technology and no modern civilization.

9. Nobel Prize.

Nobel has 355 patented inventions in his life, and has opened about 100 companies and factories in 20 countries on five continents, such as Europe and America, and accumulated huge wealth.

1895, Nobel ordered to use most of his legacy (about 9.2 million US dollars) as a fund, divide the annual interest into five parts, and set up the Nobel Prize, which is divided into five kinds of prizes (physics prize, chemistry prize, physiology or medicine prize, literature prize and peace prize) to be awarded to people all over the world who have made great contributions to mankind in these fields. In order to commemorate Nobel's contribution, artificial elements are named after Nobel.

Darwin 10

I once sailed around the world on the ship Beagle for five years, and made a lot of observations and collections on animals, plants and geological structures. He published the Origin of Species and put forward the theory of biological evolution, thus destroying all kinds of idealistic creationism and species invariance.

In addition to biology, his theory has a great influence on the development of anthropology, psychology and philosophy. Engels listed "evolution theory" as one of the three major discoveries of natural science in the19th century (the other two are cell theory and the law of energy conservation and transformation), and made outstanding contributions to mankind.

Scientists are people who objectively and digitally reproduce, understand, explore and practice the unity of real nature and unknown life, environment, phenomena and related phenomena.
