通过并列动词appreciate和need，简洁有力地表达了人们对数学的两种不同态度。
Mathematics is the unshakeable cornerstone of science and a rich source for promoting the progress of human endeavors. — Isaac Barrow
Although we are not permitted to penetrate the secret essence of nature and thus recognize the true causes of phenomena, there can still be a case where necessary fictitious assumptions are sufficient to explain many phenomena. — Leonhard Euler
The problem is the heart of mathematics. — P.R. Halmos
No problem can touch human emotion as deeply as infinity; few other ideas can inspire the intellect to produce fruitful thought as much as infinity, yet no other concept requires clarification as much as infinity. — David Hilbert
Indeed, the work of a master, extraordinary! — Évariste Galois
We appreciate mathematics, and we need mathematics. — Shiing-Shen Chern
Mathematics is a deductive discipline; starting from a set of axioms, we arrive at conclusions through logical reasoning. — Shiing-Shen Chern
A mathematician is actually an enthusiast; without enthusiasm, there is no mathematics. — Novalis
数学是科学不可动摇的基石，也是促进人类事业进步的丰富源泉。——巴罗
虽然人类无法看透自然界本质的秘密，从而认识现象的真实原因，但仍可能出现这样的情形：必须的虚构假设足以解释许多现象。——欧拉
问题是数学的心脏。——P.R. Halmos
没有任何问题能像无穷那样深深地触动人的情感，很少有别的观念能像无穷那样激励理智产生富有成果的思想，然而也没有任何其他的概念能像无穷那样需要加以阐明。——希尔伯特
这毕竟是大师的著作，不同凡响！——伽罗瓦
我们欣赏数学，我们也需要数学。——陈省身
数学是一门演绎的学问，从一组公设出发，经过逻辑的推理，获得结论。——陈省身
数学家实际上是一个痴迷者，不痴迷就没有数学。——诺瓦利斯
