    學科與采礦

    作者: 阮一峰

    日期:2006年2月25日

    突然想到一個比喻:選擇專業就好像選礦一樣。

    有的礦是新礦,埋藏淺,品味高,容易開采和出成果。新興學科(比如計算機科學)大概就是這樣的礦。

    有的礦是老礦,已經開采了幾十年甚至上百年,容易采集的礦石都已經挖掉了,剩下的礦石埋藏深、品味差、采集難度大。要獲得同樣的成果,要比以前多花成倍的氣力。我覺得歷史學就是這樣的礦,這門科學已經過度成熟了,年輕人要想在其中取得成績,非常艱難和漫長。

    不同的礦物有各自的價值,但是可以肯定的是,采集成本越低,越容易獲利。

    不同的學科也有自己的價值,但是年青人選擇不同的學科,會有截然不同的結果。選擇計算機,25歲就能獲得成果;選擇歷史學,也許要等到45歲。而成果往往與待遇聯系在一起,早出成果20年,對人生的影響不可能不大。

    一個必然的結論是,應該選擇那些容易出成果的學科,就像應該選擇那些容易挖掘的礦。
