The profession of scientist is defined as: a professional category contributor who digitally reproduces and understands, explores, practices, and defines the unity of real nature and unknown life, environment, phenomena, and related phenomena. . The following is a story about the success of scientists that I shared with you. I hope you like it!

Story of Success of Scientists Part 1

　The inventor of television, Baird

< p> One day in 1929, when the British saw television images for the first time, they were all very excited and rushed to tell each other. Among them was Baird (1888? 1946), the inventor of television, who shed tears with excitement.

Baird was born in England and was frail and sickly since he was a child. He was almost killed by the disease many times. However, his physical fragility tempered his courage and perseverance to overcome difficulties. After graduating from college, he worked in an electrical company. He was meticulous in his work and repaired several almost obsolete machines in a short period of time. He was highly valued by the company.

The relentless illness gripped him, and he had to resign to recuperate. One day in 1923, a friend told him: "Since Marconi was able to transmit and receive radio waves over long distances, it should be possible to transmit images as well." ?This inspired him a lot. Baird was determined to complete the task of transmitting images electrically. He sold his little property, collected a lot of information, and devoted all his time to developing televisions. Finally, he completed the design of the television.

It is not easy to turn design drawings into physical prototypes. A small room that serves as both a bedroom and a studio. Although the disease tortured him, he still worked tenaciously, often fighting day and night. He would eat bread when he was hungry, and sleep in his clothes when he was sleepy. If he had no money to buy experimental equipment, he would use old tea boxes, old hat box lids, and knitting bags. Needle etc. instead.

After a long period of hard work and countless failures, Baird finally used electrical signals to put human images on the screen. In 1929, the British Broadcasting Corporation allowed Baird to carry out public television broadcasting services. After the 1930s, Baird turned to the research of color television and made some achievements.

? Laplace who drove God out of the universe

Human beings have been thinking about how the universe in which they live was formed. . It was not until more than 200 years ago that a German philosopher named Immanuel Kant proposed the first relatively scientific hypothesis of the formation of the solar system, believing that the solar system evolved from a nebula. At that time, many people did not believe in this nebula theory and gradually forgot about it. Fifty years later, the French scientist Laplace (1749-1827) re-proposed this hypothesis, and based on the principles of mechanics, he used rigorous mathematical reasoning to prove the scientific nature of this theory, which in turn brought about a major change in the view of the universe.

Laplace was born in the town of Beaumont in Normandy, France. When he was a child, his family was poor and he relied on the help of his neighbors to complete his studies. Laplace had a mathematical genius and was highly appreciated by his professors when he was in college. After graduating from university at the age of 18, he was introduced to the Paris Army School as a mathematics professor by the famous mathematician D'Alembet.

For a long time, scientists have been troubled by questions such as "How did the solar system form?" and "Why does the Earth orbit the sun?" The reason is attributed to "God's first move". Laplace conducted detailed research on the formation of the universe and wrote two books: "On the System of the Universe" and "Celestial Mechanics". He believed that the solar system was formed from a primitive nebula. The primitive nebula formed a primitive fireball due to the movement and mutual attraction of particles. The primitive fireball further shrank, and due to the combined effects of attraction and repulsion, gradually differentiated to form the planets of the solar system, and finally formed the The current solar system. He calculated the characteristics of the solar system and profoundly explained the movements and orbits of the planets in the solar system. His theory was gradually recognized by the scientific community.

The nebula theory brought about a change in the view of the universe. It pointed out that the universe was developed from the movement of nature itself, expelling the Earth Emperor from the universe. When Napoleon asked Laplace why there was no God in his doctrine, Laplace proudly said: "I don't need that hypothesis." This became a famous saying of atheists at that time who despised God.

?Eastern Han Dynasty Astronomer Zhang Heng

During the Eastern Han Dynasty, there was a man who invented the celestial globe, wind instrument, and earthquake meter in China. Astronomer Zhang Heng.

Zhang Heng was born in Nanyang, Henan Province in 78 AD, from a poor family. However, he liked reading since he was a child. As an adult, he worked as a civil servant in Nanyang County for several years. Later, he resigned and returned to his hometown to devote himself to astronomical research. Three theories on the movement of celestial bodies and the structure of the universe emerged in the Han Dynasty of China, namely the "Gaitian theory", the "Huntian theory" and the "Xuanye theory". Gaitian theory holds that the sky is above and the earth is below. The sky is like a semicircular cover and the earth is like an inverted plate. ?Huntian Theory? It advocates that the sky is round, and the sun, moon and stars will turn underground. The early Huntian Theory believed that the earth was flat, and the improved Huntian Theory believed that the earth was spherical. Xuan Ye said that the sky does not have a certain shape, but is an endless space filled with gas. The sun, moon, and stars are all floating in the gas. Based on his understanding of the movement of celestial bodies and actual observations, Zhang Heng believes that the "Huntian theory" is more consistent with observational reality. He also made an "armillary sphere" that could accurately demonstrate the idea of ??armillary sky.

Another invention of Zhang Heng was the water-powered Huxian, which was the world's first water-powered astronomical instrument. The water transport muddy image is actually an astronomical clock. Through its constant speed rotation, the time can be reported. The world's first seismometer that can determine the direction of earthquakes was also invented by this ancient scientist. Zhang Heng also expounded the idea of ??an infinite universe in astronomical works such as "Lingxian" and explained the reasons why the moon reflects sunlight and causes lunar eclipses. His observation records of 2,500 stars and the calculation result of "three hundred and sixty-five degrees and a quarter degrees" are very close to modern astronomy.

Danish astronomer Tycho Brahe

Tycho Brahe, born on December 14, 1546 Born into a noble family in Sk?ne, Denmark, he entered the University of Copenhagen at the age of 14. Tycho was obsessed with astronomical observation since he was a child, and devoted his life to astronomical instrument manufacturing and astronomical research. The observational data and information he accumulated throughout his life were of great help to the later famous astronomer Kepler.

In February 1576, the King of Denmark gave Tycho Wenfeng Island in the Denmark Strait and allocated a huge sum of money to Tycho to build a large observatory on the island. This observatory is known as the "Celestial Castle". It is large in scale and well-equipped. Almost all the astronomical instruments used are designed and manufactured by Tycho. The most famous of these is Tycho's Quadrant. The observatory also has supporting instrument repair shops, printing offices, libraries, studios and living facilities. Tycho worked here for 21 years and re-measured a series of important astronomical data. His measurement results were very close to modern values.

Tycho continued to improve observation instruments, such as introducing additional collimators on the speculum, and found a transverse division method that was both exquisite and convenient, improving the accuracy of the instrument. He determined the atmospheric refraction correction table, which provided a good reference for future generations' observation activities. By redetermining the positions of stars, Tycho compiled a catalog of more than 1,000 stars that was more accurate than ever before.

After the death of the king in 1588, the observatory was very difficult to fund. Tycho struggled to maintain it for 10 years, and was forced to close the observatory in March 1597. Tycho died on October 24, 1601.
