開學

期待嘅 fall sem 又開始喇,呢幾日叫做教得幾快 (以第一堂黎計) 嘅 course 可以叫 MATH321 及 MATH305。

(除非特別標明,以下所有 course code 均指 MATH)

星期三. 因為冇野做去 sit 下 217。全埸爆滿...,好多人 sit,原來 A 教授有一種規則,就係你喺佢個 first quiz 到 ``do well" 就可以去 reg 佢個 course (不需 al pure A 或 024 (或其他) 最少 A-),難怪咁多人 sit 喇。不過聽講 203 一樣好多人 sit,啲學生未免太過份喇,搞到原本班學生冇位……。

今年 203 textbook 係用 rudin,呢屆真係好幸福,第一年就由 metric space 開始講起。有好有壞喇,以嚴教授果份 notes 黎教嘅話我最後學得好少 point-set topology on metric space (大部分相關知識都係李教授嘅 370 到學返黎的),但相對地我開始接觸 305 嘅野 (204 的 multivariable differentiation 是煉獄的開始,linear algebra 不斷湧現...)。其實我懷疑 204 本身係 introduction to 305 (類似 202 係 introduction to 301)。

呢一日去到中午上 PHYS121,重點都係要知道交功課果個流程,其他都係一堆唔駛理嘅野...。

星期四. 如上一篇 entry 所見...,比較多堂嘅一日。321、305 李教授 (2號) 做左少少比較 deep 嘅 introduction。321 人真係好多...,305 反而好少人 sit (奇怪)。

305 第一堂李教授 (2號) 就恐嚇我地 ``Unlike MATH321, this is not a course for everyone, this course is for advanced student or student with strong background", ``This course is for student who wants to be a professional mathematician in the future" 云云。我諗...,呢啲說話只會令到學生鬥志更加激昂!

星期五. 冇乜特別,number theory...,有見識過出面嘅數學比賽都知道初等數論係非常困難...,論證雖然優美、簡單,但愈簡單嘅野對智力需求愈高 (追求初等證明是好習慣),希望應付得黎。

  1. (追求初等證明是好習慣) << absolutely not. Olympiad questions like to get around a problem by tricks. This isn't quite Math is really done. If you are too used to this sort of thinking, you'll have trouble with modern math.

  2. Maybe I should say a persue of simple proof now. Anyhow what kind of math is classified as modern math?
