（數學是科學的女王，而數論是數學的女王。—— 高斯）
The science of mathematics presents the most brilliant example of how pure reason may successfully enlarge its domain without the aid of experience.
（數學科學呈現出壹個最輝煌的例子，表明不用借助實驗，純粹的推理能成功地擴大人們的認知領域。——康德)
Pure mathematics is， in its way，the poetry of logical ideas．
（純粹數學，就其本質而言，是邏輯思想的詩篇。——愛因斯坦）
But there is another reason for the hign repute of mathematics：
it is mathematics that offers the exact natural sciences a certain
measure of security which，without mathematics，they could not attain．
（數學受到高度尊崇的另壹個原因在於：恰恰是數學，給精密的自然科學提供了無可置疑的可靠保證，沒有數學，它們無法達到這樣的可靠程度。—— 愛因斯坦）
Mathematics is the tool specially suited for dealing with abstract concepts of any kind and there is no limit to its power in this field．For this reason a book on the new physics，if not purely deive of experimental work，must be essentially mathematical.
（數學是壹項工具，特別適合於處理任何壹類抽象概念，而且，它在這方面的作用是無止境的。因此，壹本論述新物理學的書，如果不是單純地描述實驗工作的，其本質上，必定是壹本數學書。——狄拉克）
Nature’s great book is written in mathematical symbol.
(自然這壹巨著是用數學符號寫成的。——伽裏略)
