I recently saw this word and suddenly became very interested in it. I found its meaning as follows:
VIP encyclopedia
D émon de Laplace is a scientific hypothesis proposed by French mathematician pierre-Simon Laplace in 1814. This "demon" knows the exact position and momentum of each atom in the universe, and can use Newton's Law to demonstrate the whole process, past, and future of cosmic events.
Some people translate it into the devil of Laplace, and demon once means a devil in English. But I prefer to translate it into a demon. The scientific assumption of Laplace is to regard a law as a creature and think that the whole process of the universe can be determined, and such a creature is assumed to have this ability, we don't know how to call it here. But because I generally think that demons are synonymous with evil, I do not like to use the word "devil" because such creatures are not set to have the evil side defined by humans, it has a rule, and its core is a rule. In the Chinese text, the demon generally refers to abnormal things. What ordinary people know is the demon, and what people do not know or exceed the scope of understanding and ability is the demon. Therefore, it is more appropriate to translate it into a demon.
I was very excited when I first saw this word. It should be the word that represents a kind of understanding that everything knows and knows. Although the current probability theory denies its existence, any law can only adapt to one stage. No law can always be applied. There will always be another situation, but as long as it exists, as a highly confident saying today, "I understand the whole universe" is a monument to the history of human exploration.
