●巴洛克风格的弗里德里希广场，
满是涂鸦的柏林墙。此刻，有一个缺牙的小孩正望着我微笑。●数学是科学的皇后。
英译:Mathematics is the queen of the sciences. ----卡尔·弗里德里希·高斯●You know that I write slowly. This is chiefly because I am never satisfied until I have said as much as possible in a few words, and writing briefly takes far more time than writing at length. ----卡尔·弗里德里希·高斯
●We must admit with humility that, while number is purely a product of our minds, space has a reality outside our minds, so that we cannot completely prescribe its properties a priori. ----卡尔·弗里德里希·高斯
●任何一张开列有史以来三个最伟大的数学家的名单之中，必定会包括阿基米德，而另外两人通常是艾萨克·牛顿和卡尔·弗里德里希·高斯。不过以他们的宏伟业绩和所处的时代背景来比较，或拿他们影响当代和后世的深邃久远来比较，还应首推阿基米德。 除了艾萨克·牛顿和阿尔伯特·爱因斯坦，再没有一个人象阿基米德那样为人类的进步做出过这样大的贡献。即使牛顿和爱因斯坦也都曾从他身上汲取过智慧和灵感。他是“理论天才与实验天才合于一人的理想化身”，文艺复兴时期的达·芬奇和伽利略·伽利雷等人都拿他来做自己的楷模。阿基米德。E.T.贝尔评价阿基米德 ----E·T·贝尔《数学人物》
●The problem of distinguishing prime numbers from composite numbers and of resolving the latter into their prime factors is known to be one of the most important and useful in arithmetic. ----卡尔·弗里德里希·高斯
●It is not knowledge, but the act of learning, not possession but the act of getting there, which grants the greatest enjoyment. ----卡尔·弗里德里希·高斯
●It may be true, that men, who are mere mathematicians, have certain specific shortcomings, but that is not the fault of mathematics, for it is equally true of every other exclusive occupation. ----卡尔·弗里德里希·高斯
●Battle not with monsters, lest ye become a monster, and if you gaze into the abyss, the abyss gazes also into you .
