有人问一位艺术家是怎样雕刻出栩栩如生的人像来的,艺术家回答说:“拿一块石头来,把多余的部分砍掉就是了.”看来,艺术家的创造并没有固定模式,然而,他所用的工具却可以一一列举.数学推理也是如此,很难说出用什么方法便能解决什么数学问题.但数学推理常用
Someone asked how an artist carved a lifelike figure. The artist replied: “Get a stone and cut off the extra part.” It seems that the artist’s creation has no fixed pattern. However, The tools he uses can be enumerated one by one. Mathematical reasoning is also such that it is difficult to say what mathematics problems can be solved. However, mathematical reasoning is commonly used.
