详情介绍
东汉末年,献帝无能,大权全落入了曹操手里,由于战绩显著,从一开始的将军到丞相,后来又封魏公,到最后献帝封曹操为魏王,并且加九锡,九千岁,位仅次于献帝一人之下。
东吴的孙权害怕有朝一日曹操率兵攻打东吴,以报赤壁火烧之仇,于是就臣服了曹操。
为讨好曹操,孙权送给曹操一头大象。由于这种动物只有在南方的热带地区才能见到,中原一带的人从来没有见过这样的庞然大物,所以这头大象让曹操感到非常稀奇。
曹操很想知道这头大象究竟有多少重量,可是当时没有称这样重量的大秤,怎么办呢?曹操召集文武百官共同商议,人人绞尽脑汁也想不出任何办法。
这时,曹操六岁的小儿子曹冲打人群中钻出来,对曹操说:“父王要称这头大象,这有什么难的?先把大象牵到木船上,水在船帮上淹到哪里就刻个标记,然后把象牵走,抬石头到船上,压到刚才的标记,再把石头一块一块过秤,不就可以算出大象的重量了吗?”
曹操听罢,喜出望外,连忙命人照着儿子说的办法做。
启示:细心观察微小事物,善于学习,善于分析思考就能发现深奥的科学秘密,或者能在一些看来很平凡的科学领域产生重大的突破。
