“智慧數學”故事(2)——數學何用?

智慧數學研究所     陳士文

近日讀到一則故事——《數學何用?》,出于職業的偏好,轉錄給數學同行。

昔日三位同學,現如今是一名會計、一名商人、還有一名教授。一日相聚,一番推杯換盞,自然談起過去上學讀書學數學的舊事。

小學畢業后做會計同學說:“嗨,還記得嗎?我們當時學的是《算術》,在我媽心中,上學學算術就是會算賬,一直鼓勵我將來呀做一名會計。”

“這不成了嗎,理想實現。”有人應他。

“還成了呢,人家都說我是死會計,小學數學老師送給我一本書,叫《算得快》,這數學就是算得快算得準吧?”會計轉頭請教教授,“現在的數學是這么回事吧?”

 “當初,我還和你一起學打算盤呢,我回想,那時的數學老師教我們的也就是算來算去的,只是……”在大學任教的數學教授呷了一口酒,接著說,“只是后來我讀初中,讀到課文《哥德巴赫猜想》,從此,數學家成了我的理想。”

“數學家?你說說,什么時候成數學家?請我們吃飯。”有人敲他。

教授嘆了口氣,說:“數學家只有陳景潤,沒有我了。苦的是從中學到大學,做了不計其數的難題怪題,還想三等分角一舉成名呢。”

“怪不得有同學說你是迂教授,依我看,學數學,不是簡單到只會做會計,也不只是去做數學家。” 商人插話了。

“不是死會計,也不是迂教授,像你,賺錢!”“無商不奸?”會計和教授輪番回應。

“不是,不是你們想的那樣,我在初中遇到了一位好的數學老師,那位數學老師真是了不起!”

商人很自豪,會計和教授催促道:“那數學……數學老師給了你什么?”

“從老師教的方程啦、反證啦,我悟出了迂回的智慧,從老師教的分解質因數、化簡啦,我悟出了化繁為簡的智慧,從老師教的畫圖啦,我悟出了事事貫通的智慧……”

商人不緊不慢,會計揶揄道:“哎,哎!哎!全是你悟的,不是老師教出的智慧。”

教授到像是醒酒了,認真道:“教學兩面,老師教得好,學生悟得多。譬如水池進水放水問題吧,有的老師就是教的死題目,有的老師卻帶學生悟出動態的思想呢。”

“說得好!來,來,來,一起喝酒。”

……

當我讀完故事,我在思考:數學不是簡單的生活實用,也不是狹窄的數學家之路,數學應給更多的人一種生活的智慧……

我想起了“智慧數學”,你呢?
