小时候,记得爸爸给我讲过一个故事:三国时,孙权送曹操一头大象,曹操很想知道大象的重量,但是象太大了,他和文武群臣都束手无策。这时曹操的小儿子曹冲说:“置象大船之上,而刻水痕所至,称物以载之,则校可知。”大家照曹冲的意见办,果然称出了大象的重量。于是大家都夸曹冲年纪小,机智聪明。其实这是一个极为简单的道理,如果两物体放在相同的船上,若吃水度相同,则质量相同。曹冲如果没有这方面的知识,他也就没有称象的高明本事了。可见知识和能力关系十分密切。
When I was a child, I remembered that my father told me a story: When Sun Quan gave an elephant to Cao Cao during the Three Kingdoms Period, Cao Cao wanted to know the weight of the elephant. However, if the elephant were too big, he and Chen Wu and Chen Chen were helpless. At this time Cao Cao’s youngest son Cao Chong said: “After setting on a large ship, and the traces of water are drawn, saying that the object is contained, the school will know.” We do according to the opinion of Cao Chong, and it really weighed the weight of the elephant. So everyone praised Cao Chong for being young and witty. In fact, this is an extremely simple truth. If two objects are placed on the same boat, if the same degree of draught, the same quality. If Cao Chong did not have knowledge of this aspect, he would not have the outstanding ability to claim imagery. It can be seen that the relationship between knowledge and ability is very close.
