种第一名。他的老师，剑桥的数学大师Béla Bollobás还专门找过老李，让他放过小
李，说小李的水平是现象级的，但是老李不让。
于是小李没有读数学的硕士和博士，他说，天才数学家李显龙离开新加坡去往普林斯顿
和哈佛，这样会让新加坡人民得到错误的信号。怪不得拉格朗日他听到自己老爸破产后
喜出望外，因为这样他老爸这样就不会逼迫他继承家业。他才能做数学了，世界多了一
个大数学家，少了一个小商人。
以下是剑桥教授对他评价的原文：
"No, he was truly outstanding: he was head and shoulders above the rest of
the students. He was not only the first, but the gap. I think that he did
computer science (after mathematics) mostly because his father didn’t want
him to stay in pure mat... 阅读全帖 |

4世纪的历史学家普罗克洛就这样认为， “Proclus (412–485 AD), a Greek
mathematician who lived around seven centuries after Euclid, wrote in his
commentary on the Elements: "Euclid, who put together the Elements,
collecting many of Eudoxus' theorems, perfecting many of Theaetetus', and
also bringing to irrefragable demonstration the things which were only
somewhat loosely proved by his predecessors".
Pythagoras (c. 570–495 BC) was probably the source for most of books I and
II, Hippocrates of Chios (c. 470–410 BC,... 阅读全帖 |

中国的男权社会维持太久了。完全赶不是西方。。。。
Hypatia[a] (born c. 350–370; died 415 AD)[1][5] was a Hellenistic
Neoplatonist philosopher, astronomer, and mathematician,[6] who lived in
Alexandria, Egypt, then part of the Eastern Roman Empire.[7] She was the
head of the Neoplatonic school at Alexandria, where she taught philosophy
and astronomy.[8][9][10] She is the first female mathematician whose life is
reasonably well recorded.[11]
Hypatia was renowned in her own lifetime as a great teacher and ... 阅读全帖 |

Google AI system proves over 1200 mathematical theorems
A new and remarkable development here is that several researchers at Google
’s research center in Mountain View, California have now developed an AI
theorem-proving program. Their program works with the HOL-Light theorem
prover, which was used in Hales’ proof of the Kepl... 阅读全帖 |
