陶哲轩（www.qq4p.com）
获得该奖项的杰出华人天才包括：
庄小威
2003年获得麦克阿瑟基金会天才奖的庄小威，是该基金会史上颁发的第一名华裔女科学
家。34岁成为哈佛大学化学和物理系的双聘教授。庄小威利用改进的荧光光谱技术来研

1） 生命的来源不是进化论探讨的重点。如果你觉得是，说明你不懂进化，或者说现在
biologist眼中的进化。
2）任意发挥，基因随机突变----这是初中生的进化。
至少你可以参考下scientific American里的资料：物种之间的差异可以反映在基因差
异，但是物种进化是缓慢的，可以说是基因表达水平的差异，简单说就是非基因的差异
，比如eQTL, regulatory element.etc。用人作为例子，全世界所有的人种，即使你比
较基因突变的差异，最后也只有< 300的基因位点（还不是基因。）
但是调节这些基因的位点就是几个million。
3）你的那种任意发挥，杂交xxx导致几个物种的线性组合生成一个新物种本身就很可笑
。课上老师给出的演化模型是以cluster来演示的，你说的是你自己的进化。

张益唐和北大数学78级
作者：汤涛
2013年是北京大学数学系成立100周年。百年大庆，作为校友，总觉得应该写点什么作
为纪念。
1904年，清政府颁布的《钦定学堂章程》规定“高等算学”隶属格致科（现在称理科）
，并且规定了算学门的课程。辛亥革命后，京师大学堂于1912年5 月1日改名为国立北
京大学。同年公布的“民国元年所订之大学学制及其学科”中格致科改名为理科，其中
包括数学门。1913年秋，北京大学数学门招收新生，标志着中国现代第一个大学数学系
正式开始教学活动。北大数学的早期学生张国焘因为后期的政治生涯为数学系增添了些
许传奇。
北大数学的一百年培养了大量的人才，先后培养出6000多名本科生、1000名硕士、博士
毕业生，一大批优秀的数学家和其他方面的专家分布在各行业， 许多人成绩斐然，得
到社会各界的高度评价。其中有30余位毕业生被选为中国科学院院士。著名... 阅读全帖 |

任何一个门类的科学研究,都是需要大量炮灰的.
这些炮灰单个看意义不大,但这个集体冲刷过程往往必须有.
要不然,什么问题是重要的,什么问题是不重要的,不会显现出来.
而"什么问题是重要的?",这个价值观,一般是一门学科的存在基点.
这就好比人和人讨论问题,80%都是说的废话和虚词.如果你真知道怎么看文章,
你会发现,一个主题很多年的集体灌水过程,其实和集体讨论问题的过程非常类似.
EE,从Bode,香浓,那奎斯特开始,每个牛人,基本上可以说都是废话不断的.

Dimension implies direction, implies measurement, implies the more and

—— Edwin A. Abbott, "Flatland"
1900年，Poincar\'e 最初用他所创立的代数拓扑研究三维流形时，提出的问题
是：如果一个流形与三维球面有着相同的同调群，那么这个流形是否同胚于 S^3？
四年后他本人给出了否定的回答。这时他已经引进了基本群，于是便将问题改成：
“如果一个三维闭流形与三维球面有相同的基本群，(即基本群平凡，或者说这个流
形单连通，) 那么这个流形是否同胚于S^3？”。这就是我们所说的“Poincar\'e
