I believe everyone knows Liu Cixin's "Three Body", right? But do you know about the three body problem?

The three body problem refers to the basic mechanical model in astrology, which refers to the motion laws of three moving celestial bodies with arbitrary masses, initial positions, and initial velocities that can be regarded as necessary points under the action of universal gravity. But we need to know that the three body question has no solution.

This is the reason why the three body people in "Three Body" want to "move collectively".

Now that you know the principle of the three body problem, the first book is easy to understand. But if you want to understand the latter two parts, you don't just need to understand them.

Overall, "The Three Body" is like this: the first part of the Earth Man is a worm, the second part of the Three Body Man is a worm, and the third part... we are all worms! Simply put, it's a fight between two insects (Trisoms and Earthlings), where one person walks over and stomps them all to death with one foot (Singer Civilization).
