A Plea for Pure Science

Rowland, Henry Augustus. "A plea for pure science." Science 2.29 (1883): 242-250:
假如我们停止科学的进步而只留意科学的应用,我们很快就会退化成中国人那样,多少代人以来他们都没有什么进步,因为他们只满足于科学的应用,却从来没有追问过他们所做事情的原理。这些原理构成了纯科学。中国人知道火药的应用已经若干世纪,如果他们用正确的方法探索其特殊应用的原理,他们就会在得到众多应用同时发展出化学甚至物理学。因为只满足于火药可以爆炸的事实,而没有刨根问底,中国人已经远远落后于世界的进步,以至于我们现在将这个所有民族中最古老、最庞大的民族当成野蛮人。
CFD未尝不是呢

小的时候 世界有一种美丽 那就是学了加法口诀 你只要会100以内的加法 你很自然的可以做出100位数字的加法 这只是一个简单的重复
而如果你学会的乘法口诀 你就可以做所有的乘法 我们的成就感很高 因为我们只要学会100以内的加法 还有乘法口诀就能掌握了所有加减法和乘法
你在偏微分之前 除开一些偶尔的案例 你也能 举一反三的战无不胜 从而感觉很自豪 而当进入偏微分之后 没有什么是具备统一规律的
而伟大的爱因斯坦和薛定谔都在晚年致力于发展一种大一统的理论 解决所有的物理学问题 而如果世界真的这样的 那么是不是少了太多的魅力?
所以我们最后承认量子力学的理论只能解决微观的问题 广义相对论的理论只能解决宏观的问题 -

just for fun:
They used to say if man could fly, he'd have wings. But he did fly. He discovered he had to. Do you wish that the first Apollo mission hadn't reached the moon, or that we hadn't gone on to Mars and then to the nearest star? That's like saying you wish that you still operated with scalpels and sewed your patients up with catgut like your great-great-great-great-grandfather used to. I'm in command. I could order this. But I'm not because, Doctor McCoy is right in pointing out the enormous danger potential in any contact with life and intelligence as fantastically advanced as this. But I must point out that the possibilities, the potential for knowledge and advancement is equally great. Risk. Risk is our business. That's what the CFD is all about. That's why we're aboard her. You may dissent without prejudice. Do I hear a negative vote? (silence around the table) Engineer, solving that imcompressible N.S. equations using PISO algorithm.
