Stupid Humenbing

Can you tell that Sudoku and Rubik's Cube are actually the same thing? The most challenging intellectual toy in human history. The latest artwork, for peace [smile]
If excellent people compete in "fun mathematics" and "intellectual toys", in terms of intelligence and brain power, instead of relying on physical strength in the Olympic Games and not using weapons to win, then how beautiful is human society?
When Archimedes was pulled away by the soldiers, he was still addicted to conducting experiments on gravity in the bathtub. The earliest hero who loves peace the most is undoubtedly Archimedes.
New technological inventions are also problems, and the latest research results are ultimately turned into weapons to compete and kill.
The more advanced extraterrestrial biological civilization (through Teacher Liang) is mocking human stupidity! [Crazy]
