詳情介紹
東漢末年,獻(xiàn)帝無(wú)能,大權(quán)全落入了曹操手里,由于戰(zhàn)績(jī)顯著,從一開(kāi)始的將軍到丞相,后來(lái)又封魏公,到最后獻(xiàn)帝封曹操為魏王,并且加九錫,九千歲,位僅次于獻(xiàn)帝一人之下。
東吳的孫權(quán)害怕有朝一日曹操率兵攻打東吳,以報(bào)赤壁火燒之仇,于是就臣服了曹操。
為討好曹操,孫權(quán)送給曹操一頭大象。由于這種動(dòng)物只有在南方的熱帶地區(qū)才能見(jiàn)到,中原一帶的人從來(lái)沒(méi)有見(jiàn)過(guò)這樣的龐然大物,所以這頭大象讓曹操感到非常稀奇。
曹操很想知道這頭大象究竟有多少重量,可是當(dāng)時(shí)沒(méi)有稱這樣重量的大秤,怎么辦呢?曹操召集文武百官共同商議,人人絞盡腦汁也想不出任何辦法。
這時(shí),曹操六歲的小兒子曹沖打人群中鉆出來(lái),對(duì)曹操說(shuō):“父王要稱這頭大象,這有什么難的?先把大象牽到木船上,水在船幫上淹到哪里就刻個(gè)標(biāo)記,然后把象牽走,抬石頭到船上,壓到剛才的標(biāo)記,再把石頭一塊一塊過(guò)秤,不就可以算出大象的重量了嗎?”
曹操聽(tīng)罷,喜出望外,連忙命人照著兒子說(shuō)的辦法做。
啟示:細(xì)心觀察微小事物,善于學(xué)習(xí),善于分析思考就能發(fā)現(xiàn)深?yuàn)W的科學(xué)秘密,或者能在一些看來(lái)很平凡的科學(xué)領(lǐng)域產(chǎn)生重大的突破。
