描述
當(dāng)回頭審視新方法的推演過程和數(shù)學(xué)的時候,作者拓展了對思維和數(shù)學(xué)的認(rèn)識。數(shù)學(xué)簡潔,清晰,可靠性、模式化強。在數(shù)學(xué)的發(fā)展史上,處處閃耀著數(shù)學(xué)大師們創(chuàng)造力的光輝。這些創(chuàng)造力以各種數(shù)學(xué)定理或結(jié)論的方式呈現(xiàn)出來,而數(shù)學(xué)定理最大的特點就是:建立在一些基本的概念和公理上,以模式化的語言方式表達(dá)出來的包含豐富信息的邏輯結(jié)構(gòu)。應(yīng)該說,數(shù)學(xué)是最單純、最直白地反映著(至少一類)創(chuàng)造力模式的學(xué)科。
