Conway Surreal Numbers

John Conway (82) passed away last month due to COVID19.

He made Math fun by playing Math games.

Surreal Number = 超现实数

Conway 是"大师级"数学家,他的这个 Toronto lecture “Sur-Real Numbers” 值得 花 1hr 细听, 茅塞顿开:
1) 数学是"玩"出来的 : 他玩”Go” 围棋,发现Surreal number (a Field structure, its addition operation forms a “Additive Group”).

2) Cantor 的逸事: 发明 Set Theory, Infinity,Unionize Mathematicians by 1st ICM (International Conference of Math)。法国打算 boycott 战争敌人德国,Poincare 带30法国数学家半场突然出席 – 数学无国籍 !

3) French “Positif” Integers include ‘0’ , better than English’s “Non-negative” Integers.

4) 他的 Q&A 更精彩… 可以"看"出大师的思路。

Cédric Vilani (Chinese) Interview

French Fields Medalist Cédric Vilani 中文interview: 他苦思证明数学/物理定理,在第 1001 th 夜 @4am,”好像上帝给他打电话 – Un coup de fil du Dieu” , 突然开窍…

他从政加入Macron的小党 “En March”,当MP, 今年竞选 Paris Mayor.

2017 年 他引入 “Singapore Math” 进法国小学。
