Differential Geometry

雖然
蔡宜洵的推導跟證明沒有很嚴謹
do Carmo也稱不上concise
但是
蔡宜洵的lecture提供了很多直觀的想法與歷史上發展的過程
do Carmo的題材跟習題很有趣

不好好唸geometry實在太可惜了

但是真的很有vision

然後看看台大
幾年前搞了個神經生物與認知科學研究中心
然而一直沒有研究或教學上實質的整合與創新的ideas
成員更有許多明明就不是作neurosciece or cognitive science的教授
唉　台大

塔羅灣溪

lag很大...

上禮拜看新聞說"塔羅灣溪滾滾惡水毀了廬山"
一直覺得塔羅灣溪這個名字很熟悉
今天才發現
去年走能高越嶺時曾在塔羅灣溪的兩大源頭之一溜冰跟玩雪XD
有圖有真相

現在生物科學期刊都流行SOM
那我也來給幾個好了

蔡宜洵今天說
Riemann這篇文章在math, physics and philosophy上都有著重大的意義
所以特別把德文原文、中譯、英譯三個版本都找出來

值得注意的是
此英譯版本原本刊在1873年5月的nature (pdf files: part 1, 2)
今日在nature還是science一年要是能看到一篇數學文章就要偷笑了
真哀傷...

海角七號 再論Heidenröslein

終於有人注意到深藏在野玫瑰歌詞中的意涵了──
殘酷的海角七號，鄉民不解的野玫瑰
雖然內文有些陳述是錯誤的
但並無大礙

野玫瑰的歌詞真的值得細細體察
特轉錄歌德的原作於後──

Sah ein Knab' ein Röslein stehn,
Röslein auf der Heiden,
war so jung und morgenschön,
lief er schnell, es nah zu sehn,
sah's mit vielen Freuden.
Röslein, Röslein, Röslein rot,
Röslein auf der Heiden.

Knabe sprach: "Ich breche dich,
Röslein auf der Heiden!"
Röslein sprach: "Ich steche dich,
dass du ewig denkst an mich,
und ich will's nicht leiden."
Röslein, Röslein, Röslein rot,
Röslein auf der Heiden.

Und der wilde Knabe brach
's Röslein auf der Heiden;
Röslein wehrte sich und stach,
half ihm doch kein Weh und Ach,
musst' es eben leiden.
Röslein, Röslein, Röslein rot,
Röslein auf der Heiden.

今早在家裡翻國小的音樂課本
發現野玫瑰是在五年級教的
小學生如果能懂野玫瑰的隱喻那就真的太超過了

斷章 Oculus

原來每一個願望的背後都藏著一些失望的憂愁

Learn to be lonely.
But being a human it's nearly a mission impossible.
Here arise bubbles of aspirations.
To be leaned on, to depend on.
To love, to be loved.

Voglio vederti danzare come le zingare del deserto
con candelabri in testa o come le balinesi nei giorni di festa.

'Tis life.

The Movie of the Year: 海角七號 Cape No. Seven

當陽光再次回到那　飄著雨的國境之南
我會試著把那一年的故事　再接下去說完 ...

劇情音樂台詞的搭配很完美
場景對話貼近許多台灣人的經驗
內容反省深度也是夠的
[這需要用多一點的心去感受
或許還需要曾有過類似的體驗]
最大的缺點就是
情書段落和正在進行中的故事主線連結的力道太弱

PTT movie板上海角的討論文已經逼近1400篇了
多言無益
我要說的是
這是今年第一部讓我有歡笑也有淚水的電影
[非常意外舒伯特的野玫瑰催淚效果那麼好XD
剛看完電影時其實並不太能理解為什麼選野玫瑰
回來後仔細讀了歌詞才有點明白裡面的涵義]

--------------------------------------------------

關於野玫瑰
plamc大提供的訊息如下──

茂伯為什麼突然會彈野玫瑰當安可曲 而且為什麼大家都很能配合?

這梗我第一次也LOSS掉一大半

首先
茂伯初出場
在田間騎車時哼的就是日文歌詞的野玫瑰
表示他很熟這首歌

阿嘉第二次到他家時他正拿著月琴
調一調以以後開始自彈自唱野玫瑰
阿嘉跟著哼
因此茂伯知道阿嘉會這首歌

最後一次練習時
茂伯問 : 你們就這樣甘心了嗎? 以後
鏡頭轉到晚上各人的行動
茂伯+水蛙到機車店借地方練習(野玫瑰)
而勞馬在練口琴(應該也是吹野玫瑰)

也就是說
在阿嘉不知情的狀況下
茂伯已經陰謀準備好了安可曲...老奸巨滑啊XD
他知道阿嘉一定會野玫瑰這首歌
所以就選定這首來當預謀的安可曲

原來野玫瑰的出場是有鋪陳的XD
