In fact, scientists include profiles of famous scientists in physics, mathematics, chemistry, and biology.
Scientist is a general term that refers to experts in the field of natural sciences and people who use scientific methods to conduct research.
Traditionally, mathematics is also a science, but modern people tend not to think of mathematicians as scientists, because the methods of mathematical discovery and scientific discovery are different: scientific discoveries can generally be proven through experiments, but mathematics However, many of the theories are just a theory without experiments to prove it.

Let’s start with our country’s scientist Zu Chongzhi!
The Story of Mathematician Zu Chongzhi
The grandfather of Zu Chongzhi (429-500) was named Zuchang, and he was an official in charge of court buildings in the Song Dynasty. Zu Chongzhi grew up in such a family and read many books since he was a child. People praised him as a learned young man. He was particularly fond of studying mathematics and astronomy and calendars. He often observed the movements of the sun and planets and kept detailed records.
Emperor Xiaowu of the Song Dynasty heard about his reputation and sent him to work in the "Hualin Academic Province", an official agency specializing in academic research. He was not interested in being an official, but there he could concentrate more on studying mathematics and astronomy.
Our country has had officials who studied astronomy in all dynasties, and calendars were formulated based on the results of astronomical research. By the time of the Song Dynasty, the calendar had made great progress, but Zu Chongzhi thought it was not accurate enough. Based on the results of his long-term observations, he created a new calendar called the "Daming Calendar" ("Daming" is the reign name of Emperor Xiaowu of the Song Dynasty). The number of days measured in each tropical year (that is, the time between the two winter solstice points) measured by this calendar is only fifty seconds different from that measured by modern science; the number of days it takes for the moon to circle around is not different from that measured by modern science. For a second, you can see how accurate it is. In 462 AD, Zu Chongzhi asked Emperor Xiaowu of the Song Dynasty to promulgate a new calendar, and Emperor Xiaowu convened ministers for discussion. At that time, Dai Faxing, a favored minister of the emperor, came out to object, believing that Zu Chongzhi's unauthorized change of the ancient calendar was an act of deviance. Zu Chongzhi used the data he studied to refute Dai Faxing on the spot. Dai Faxing relied on the emperor's favor and said arrogantly: "The calendar was established by the ancients and should not be changed by future generations." Zu Chongzhi was not afraid at all. He said solemnly: "If you have factual basis, just use it to argue. Don't scare people with empty words." Emperor Xiaowu of the Song Dynasty wanted to help Dai Faxing, so he found some people who knew the calendar to argue with Zu Chongzhi, but they were all refuted by Zu Chongzhi. . However, Emperor Xiaowu of Song Dynasty still refused to promulgate the new calendar. It was not until ten years after Zu Chongzhi's death that the Daming Calendar created by him was implemented.
Although the society was very turbulent at that time, Zu Chongzhi still studied science tirelessly. His greater achievement was in mathematics. He once commented on the ancient mathematical work "Nine Chapters on Arithmetic" and compiled a book "Zhu Shu". His most outstanding contribution was the fairly accurate calculation of pi.
After long-term and painstaking research, he calculated that pi was between 3.1415926 and 3.1415927, becoming the first scientist in the world to calculate pi to more than seven digits.
Zu Chongzhi was a versatile man in scientific inventions. He built a compass. No matter how the car turned, the bronze figure on the car always pointed to the south; he also built the "Thousand-mile Ship", which is in Xinting After trial navigation on the Yangtze River (southwest of today's Nanjing City), it could sail more than a hundred miles a day. He also used water power to turn stone mills and pound rice to grind millet, which was called "water mill".
In Zu Chongzhi's later years, Xiao Daocheng, who controlled the imperial guards of the Song Dynasty, destroyed the Song Dynasty.
Next, the poster should have heard of the great scientist Edison!
Thomas Alva Edison (February 11, 1847 - October 18, 1931), American inventor and businessman, who developed many important devices people. "The Wizard of Menlo Park" in New Jersey was the world's first industrial research laboratory where an inventor used mass production principles to produce inventions. Edison is regarded as the person with the most inventions of our time. , has 1093 patents in his name. Most of the inventions were not original, but were improvements on other patents, and in fact many were invented by his many employees. As a result, Edison was often criticized for not sharing these credits. However, Edison received patents from many countries, including the United States, Britain, France and Germany. In 1892, he founded General Electric, which later became the largest company in the United States: General Electric Company. It owned 24,414 patents including Edison's 1,093 patents. In 1908, Edison founded the Motion Picture Patents Company (commonly known as the Edison Trust), a conglomerate of nine major film studios.
In the early 1900s, Edison bought a villa in Formmel, Florida as a cold retreat. Automobile magnate Henry Ford lived across from this villa. They remained friends until Edison's death. "Edison and Ford Winter Estates" is currently open to the public.
Main inventions

Furthermore, Einstein is the famous scientist who introduced the theory of relativity.
Albert Einstein (March 14, 1879 - April 18, 1955), a famous theoretical physicist and the founder of the theory of relativity.
Einstein was born in Ulm, Germany, into a family of small owners who ran an electrical appliance workshop. A year later, he moved to Munich with his family. In 1894, the family moved to Milan, Italy. In 1895 he transferred to the state high school in Aarau, Switzerland. In 1896, he entered the Normal Department of the Federal Technical University of Zurich to study physics and graduated in 1900. Obtained Swiss citizenship in 1901. In 1902, he was hired as a technician by the Swiss Patent Office in Bern, engaged in technical appraisal of invention patent applications. He used his spare time to conduct scientific research and made historic achievements in three different fields of physics in 1905, especially the establishment of the special theory of relativity and the proposal of the quantum theory of light, which promoted the revolution in physics theory. In the same year, he obtained a doctorate from the Federal Technical University of Zurich with his thesis "A New Method for Determining Molecular Size".
Newton, the scientist who discovered gravity.
Sir Isaac Newton? (January 4, 1643 - March 31, 1727), British mathematician, scientist and philosopher, and an enthusiast of alchemy at that time .
The law of universal gravitation proposed by him in "Mathematical Principles of Natural Philosophy" published on July 5, 1687, and his Newton's laws of motion are the cornerstones of classical mechanics. Newton also and Leibniz independently invented calculus. He left behind more than 500,000 words of alchemical manuscripts and more than 1 million words of theological manuscripts.
Newton is known as one of the greatest scientists in human history. His law of universal gravitation unified the movement in the sky with the movement on the ground for the first time in human history, providing strong theoretical support for the heliocentric theory, allowing the research of natural science to finally break free from the shackles of religion.
Newton also discovered the color composition of sunlight and built the world's first reflecting telescope.
Here, I will make a summary. Edison once imitated a hen to hatch eggs; Einstein had a strong curiosity; Newton had a strong ability to observe. Therefore, a scientist should have curiosity, observation, and perseverance (Edison).
The ways to become a scientist include universities, hospitals, and academic research, etc. The author can set doctorate as the first goal, and then slowly move towards the goal of scientist.
I wish the poster success!
