世界是由少数人推动的

April 20, 2008 1:13 pm UTC | In Life, Tech

很久很久以前,我有过一台电脑,CPU 是 80486SX 33MHz,这个 486SX 没有数学协处理器(floating-point unit、FPU、浮点运算单元,用硬件实现浮点数的快速运算),对现代电脑来说 FPU 已经是一个不可缺少的部件。我记得当年 486SX 上生成艺术字就特别特别的慢,比同速度但带 FPU 的 486DX 慢十多倍,真是土鳖啊。

当年英特尔设计 486DX 有一个缺陷,于是他们搞出一个销售策略是,如果测试出来某个 486DX 主电路是好的,但是 FPU 是坏的,那么就把 FPU 部分砸掉,然后把这个芯片当作 486SX 低价销售。这种销售方式很常见,比方我们实验室买的一种镜子,反射率越高价格也就越高,但是不同反射率镜子的生产工艺和成本完全相同,只不过由于生产过程中各类不确定因素导致镜子质量有好有坏,质量好的也就卖得贵一些。农民卖苹果也会分等级,大的苹果卖贵一些,虽然种苹果的时候他未必在大苹果上多花了力气;如果你跟他讲,苹果大小是一个正态分布,大于 +2σ 叫特等品,恐怕农民是听不明白的。

有不少人认为,世界是由少数人推动的。Kisstar 同学说,学术界真正有用的结果都是 top 10% 的牛校牛人搞出来的,大多数人都是陪练,跟着灌水而已。从时间纵向来看,确实有一小部分人为人类进步做出了很大的贡献。然而从横向角度来看,人类是作为一个整体在进步,个人贡献呈现一个正态分布,这样的分布下,必然会有一小部分人对人类进步的贡献极多。这是地球上这么多人的统计规律,所谓大样本出奇迹,世界是不是由少数人推动的,这纯粹就是一个统计学的解释问题。

就像前文所述的一种销售策略,我们是在出卖自己的智慧寻求人类进步。如果你潜质很牛,那么就不应该浪费这种能力,而应该积极的开发潜能尽力推动人类的进步。而大多数人往往觉得自己碌碌无为,并没有对人类进步做出直接的贡献,这种情况下也没有什么好气馁的,应该看到,我们为牛人出现的极小概率的分母贡献了一份,没有我们这些巨大的样本,奇迹也是不会出现的。通俗点说,你觉得是 100 个人的小村庄里面容易出一个牛顿,还是几亿个人的地球上容易出一个牛顿?

活着,就是对人类的贡献。

  15. 由图看出康神和杀人犯与强奸犯在对称的位置上,由此可以推出康神是反-杀人犯和强奸犯的!由此可以推出康神是侦探或警察。。。。。Orz….

  16. “学术界真正有用的结果都是 top 10% 的牛校牛人搞出来的”,从哪得来的?!!!, 爱因斯坦不是名校, said like that,very stupid

  17. 楼上oracle质疑地好。要给我们这些笨蛋一线希望嘛。如果在“都是”前面加一个“基本上“,貌似更有逻辑。

    这个评论系统有点烂,装个Ajax的插件吧。找不到问我。

  19. 刚刚又来读了一遍。
    我发现这个图没有问题!贡献没有负值是迎合了“活着,就是对人类的贡献”的结论。
    伟大伟大,为我的肤浅道歉,orz

    因此,希特勒也有贡献?
