或

另外每章都有講議可參考，作業題目也在講議上。
μ 上課方式(投影片、團體討論、老師教學風格)
老師板書，英文授課，不知為何課程網沒有註明，但影響應該不大。
會好好講每個問題的動機、推導、舉例和整理。
然後可能是因為凝態的冷氣都要比較低能，我有時會不小心睡著，
醒來就發現世界不一樣了。因為聽不懂內容，只好筆記一些老師講的奇怪的話：
9.10 Garbage truck
Like a garbage truck, it's the flies(field) that flies around, not the garbage truck itself (that has energy).
What has wheels and flies? A garbage truck.
9.10 Unicorns exists
Suppose unicorns exist, for a type of unicorn, I'll name it exist-unicorn.
Since it is called exist-unicorn, it exists.
9.17 Girl friend and Gorillas
Though it looks boring, if you want to know about something, you have to spend time with it.
If you want to know about gorillas, you have to spend your time with gorillas; If you want to know about your boy or girlfriend, you have to spend time with him or her.
Maybe we should not think of gorillas and boy or girlfriend as the same, but it's true.
9.17 Notation
Open sets U_1, U_2, U_3, U_4
Their union U_1 U U_2 U U_3 U U_4
Aha... I regret using U
9.31 Mobius ring
Some people correct me every time I say this word. We have a German pronounce it.
German girl in class: Mobius
Professor: Say it three times
German girl: Mobius, Mobius, Mobius
Professor: Okay, I'm not sure if I could reproduce this.
9.31 Take a picture
I want to take a picture, I told my friend I have 80 students in my class, he doesn't believe me.
9.31 Confusing
Is this confusing or obvious?
Or both?
10.08 Doughnut
If we have alien penpals .... their planet might be like a doughnut (draws a sunny side up egg on the blackboard) or it might have two holes (draws another hole and curves of the doughnut.) I have an idea to open a doughnut shop and sell doughnuts of different topology, then math-oriented people would like to try all of them.
10.15 Twins paradox
Suppose we have a set of twins, the brother goes on a rocket while the sister stays on Earth. (There is no word for "elder brother" in English, so they have to be in different genders)
... Then the sister (points at the stick figure on Earth), this is the sister, right? I can't remember, let me draw some hair.
... If the brother uses a telescope to look at her sister through the journey. It might sound creepy, but he could do that.
10.15 Word & LaTeX
This is like Word and LaTeX. If you use Word, you get something fast, and it looks fine. If you use LaTeX, you spend more time in the beginning, but you get something more beautiful.
Do not quote me.
10.22 Nothing
This entry could be nothing but zero ... nothing but zero is simply nothing.
10.22 Gravitational field
If you have a strong gravitational field, and something in it... (tosses the chalk in his hand)
12.03 Explanation
Is this too abstract? Do I have to explain this in a different way?
I don't have a different way.
Okay, this is homework, please tell me if you find a different way.
12.03 Change of variables
You can always change variables, no one could forbid you to do this.
To me, this is basic human right.
σ 評分方式(給分甜嗎？是紮實分？)
70% 作業；30% 期末
成績只送通過與否，沒有等第，我也是拿到成績才發現...
ρ 考題型式、作業方式
只有期末考試，普通的是非、簡答、問答，有提供考古。應該沒有為難人。
作業四次各五題，可手寫或打字，好象每次都是簡單題到難題。
ω 其它(是否注重出席率？如果為外系選修，需先有什麼基礎較好嗎？老師個性？
加簽習慣？嚴禁遲到等…)
我不知道老師在不在意出席人數，反正不會影響成績。
我是少數外系的，大概有用到一些微積分和線性代數知識吧。
如果有強大的想像力或是數學很好或是擅於閉著眼睛操作符號，應該很有幫助。
比較麻煩的是，有時上課或作業舉例用的東西沒看過，就得另花時間看懂。
（如 Maxwell's equation, Schrödinger equaton）
加簽狀況我沒印象，教室算滿，但我外系選得到課，所以應該不是大問題。
Ψ 總結
其實我只是畢業前想用 112ip 賺 P 幣順便清硬碟而已。
