"Give me a fulcrum and I will move the earth." The famous words of Archimedes, an ancient Greek mathematician, are still told by people today.

Thousands of years have passed, "Give me a fulcrum and I will move the earth." The meaning of this sentence has already gone beyond the original context mentioned by Archimedes, and has been attached with more humanistic and social implications such as philosophy of life by later generations. If Archimedes used this sentence to express the great power of lever principle and mathematical logic, it is still clear, then, after transcending the field of mathematics and being attached with the significance of humanities and social sciences, the connotation of this sentence is difficult to grasp. Do you want to express that "I" can do anything, even the earth can shake it, or do you want to convey a helplessness and confusion that you can't find a fulcrum? As a symbol or metaphor, what is a "fulcrum"? What is the "earth" to shake? In different language environments and expressions, their meanings are also millions.

According to the principle of leverage, it is a practical problem: when we have certain conditions, we can do many seemingly impossible things. For example, it is hard for us to imagine that we can move the earth, but when we have a fulcrum, this is not a problem. According to scientists' calculations, the lever to pry the earth needs to extend beyond the Milky Way!
