Laplace 1749 was born in a poor family. His father is a farmer. /kloc-At the age of 0/6, he entered the University of Caen to study mathematics. After finishing his studies, he went to the capital, Paris. He is still very young. Like the famous mathematician Da Lambert, he submitted a letter of recommendation from a famous person, hoping to find a job of teaching mathematics, but Da Lambert refused. Laplace returned to his residence and wrote a letter to da Rambo. This time it's not a letter of recommendation, but a letter about the principles of mechanics. In order to show his talent, da Lambert replied: Sir, please remember that I am not interested in your recommendation letter, and you don't need any recommendation letter. You yourself are the best recommendation letter. So, with the help of this famous professor, he got a professor at the Paris Military Academy.

1783, Laplace was a member of the entrance examination committee of this military school, and Napoleon was also tested by him, so Laplace and Napoleon were very familiar. Later, when Napoleon came to power, he was appointed Minister of the Interior, but he was a political speculator. In the turbulent era of France, no matter which political party was in power, he went to please, so he was quickly dismissed by Napoleon, and Napoleon once laughed at him for trying to put

He wrote two immortal works, Celestial Mechanics and Probability Analysis Theory. In front of these two books, he wrote many non-technical explanations, so Laplace won the' Newton of France'. In this book, he also shows that the author is an invincible master in this subject. When Napoleon blamed the celestial bodies for not mentioning God, Laplace said, I don't need that premise.

Laplace's achievement is great. Now there are so-called Laplace transformations, Laplace equations, Laplace expansions in mathematics ... He just died Newton at 100, and his last sentence was "We know very little, but we don't know much". In mathematics, he is often compared with another great mathematician, Lagrange, but apart from their similar age and names beginning with L, their personalities are far from each other. Lagrange is perfect in form and content, and he will explain his argumentation process carefully. He thinks mathematics is a lofty art, while Laplace doesn't like explanation and doesn't pay much attention to process. He only cares about whether he can get the result accurately. He thinks mathematics is just a scientific tool.
