胡言亂語

星期五,台大新生訓練,九月十八日開學。

心理系南北館把大學部與研究所分隔得很開,完全沒有感受到新生swamp進來的感覺。真是神奇。某些老師認為這樣的分隔是件好事,因為大學部學生對研究而言多是「噪音」。這樣的說法,聽起來總是有點奇怪的地方。^^

星期六下午帶姪子去上數學課,羅斯福路上塞車塞得厲害,一輛一輛的遊覽車從各處湧入台北市中心,進行挺扁的活動。

很多事情同時在發生著,思考這些事情的意義變成一件很複雜的事情。但恐怕很多事情的問題是在於大家在「思考事情的意義」這件事情上花得時間太少。



最近少看新聞,各台新聞對事情的呈現與處理常令人不悅。看到遍是單一且煽情的展現事情的面貌,看了令人生氣,但偶爾還是會觀看一下事情發展的現況。看到穿著高中制服的學弟妹在數萬人集結的場合用高亢的聲音「發表」他們心中的「感言」,不禁去回憶我們曾經參與些許社會運動的年代,也想像著這些熱血青年在台上時心理亢奮及「壯烈」的感受。

大部份同年的人還來不及參與三月學運。但也曾數次因為擁護自己相信的世界觀而走上街頭。當年的我們不也是相信自己在參與一場歷史的盛會,相信自己雖然沒有來得及參與三月學運,來不及為民主的發展拋顱灑血,也參與了十萬人和平上街抗議台是反小白球運動之類的活動。

雖然數年之後的此時,我們還是無法決定這些運動與理念的絕對意義,但思考自己十幾年前的熱血,常覺得年輕人的理想與熱情是如此容易受到鼓動。我們常不清楚我們奉獻熱情的活動後面究竟是什麼樣的意圖與組成。

「運動」通常都複雜的不得了。每個參與運動的人動機也許都不同,說得與想得也都不同。面對著這些複雜的符號與言,在動與不動之間,也是許多爭扎。不喜歡這個複雜遊戲的人,有另一套系統可以參與嗎?真是令人困惑呢!

漫長的求學之路..

很久沒有寫新的東西了。其實回到學校的系統裏之後有非常多感觸,只是每天都忙著在眾多紛擾思緒裏匍伏前進,適應一個完全不同的環境。

心理學在我們畢業的十年之間有許多研究發現與研究方向的改變。尤其是逐漸轉向人類生理機制與腦神經科學的研究方法。前者逐漸走向genes knockout或是分子生物的途徑,後者則重視腦神經反應與行為模式的推論關係。兩者都非常重識實驗數據的模型分析,除此之外,後者因為採用許多模型推論的方法,實驗設計的嚴謹度非常重要,常必須使用程式來產生標準化的刺激。在這裏一天到晚聽到的是訊雜比,傅利葉轉換、波形...等。大部份的研究生也都具備程式設計的能力,以電腦呈現標準化的刺激材料。這些都是十年前所沒有的東西。

離開校園許久,早就不大需要使用的三角函數、微積分... 等數學工具,現在全部要重新來過。重新從高中數學開始複習起。

常常想要對幾位從文科轉唸理科博士或是從理科轉唸文科博士的朋友們致敬。這真是一條走來不易的道路啊。

冥王星從九大行星裏除名

在捷克召開的國際天文學會,天文學家在星期四投票決定將Pluto從九大行星裏除名,重新被定義為dawrf planet大新聞。

Pluto被除名的主要原因在於國際天文學會新採納了一個行星的定義,該行星必須是主宰該區域的主要星體,才能被定義為太陽系裏的主要行星。

有些天文學家對這個決定頗為失望,甚至認為這是語言學上的災難:

"We now have dwarf planets which are in fact not planets. I consider this a linguistic catastrophe. I think the union is going to get a lot of flak for this, in doing it in such a muddy way," said Owen Gingerich, chairman of the IAU's official planet definition committee.


不管如何,大家的地球課本內容就是要改寫了。 Link: Astronomers expel Pluto from the planetary club

The female brain

Way back in February I read from brain wave that there's a new book called "the Female Brain" due to be published in August. Today I found from news it's out now. This book is written by a scientist called Louann Brizendine.

In her new book, "The Female Brain," Brizendine says that women are better than men at remembering the details of emotional events because their brains are structurally and chemically different. This is not essentialist malarkey; scientists have studied living, thinking female (and male) brains with PET and MRI scans. Simply put, the hippocampus -- site of emotions and memory formation -- is larger in women, as are the brain areas for language. Men, on the other hand, have larger brain centers for action and aggression. (They also have 2 1/2 times the brain space devoted to the sexual drive, according to Brizendine.) Much of these variances start in utero, during the eighth week of pregnancy, when the then-female brain will either receive a testosterone surge or not. The screenwriters of "Click," then, weren't so far off the mark.
So there are fundamental differences in the brains between men and women. Though it's more or less a cliché. It's still interesting for me to know the scientific facts behind this well known phenomenon. However the reviewer gave this book quiet merciless critiques.
Brizendine sounds surprisingly naive elsewhere in the book as well. After speculating that, like prairie voles, some men may have a gene sequence for monogamy, Brizendine delivers this scoop: "We now know women cheat, too." One wonders how many studies Brizendine had to sift through before coming to this conclusion. And while it's fascinating to learn why women's brains get in their way of having round-the-clock sex, do we really need a neuropsychiatrist to tell us that a woman won't have sex with her partner while she's angry at him?

For a scientist, Brizendine relies heavily on anecdotes. Even though she says that child development is "inextricably both" nature and nurture, she starts Chapter 1 with a vivid story of a patient who gave her 3-year-old daughter a toy fire truck instead of a doll. One afternoon, the patient walks into her child's room to find her rocking the truck and saying, "Don't worry, little truckie, everything will be all right." Though this is hardly proof that the girl's brain was hardwired for nurturing -- we don't know what other environmental influences (television, friends, babysitters, other female figures) may have shaped her -- it serves to support Brizendine's point that "there is no unisex brain.
As far as a scientific book is concerned, we might expect more scientific information from this book. However I was talking with my publisher friends about how publishers "wrap" and promote publishing nowadays. Since lots of readers don't really "think" critically, the publishers try to draw attentions by putting some sensational anecdotes in front of readers' faces. I've been reading several popular scientific books with similar layout. I wonder whether it's because of the publisher or the writer so the book doesn't present so much scientific arguments and facts. I need to think seriously whether to spend money on that book or not now. ^^

Chinese senior ambassador to UN said: Every inch of territory is more valuable than people's life

I heard the most ridiculous interview with Chinese most senior ambassador to UN about the Chinese military expansion.
he said..

the moment when Taiwan goes independent supported by WHOEVER, china will have no choice.. will have to do "business" through whatever means we'll do business at any cost.. ... one inch of territory is more valuable than our people's life ... he said.. it's better for US to shut up.. to keep quiet.. is much much better
...it's hight time to shut up, don't tell china what's good for china.. THANK YOU VERY MUCH

It's more vivid to listen to the tone in his conversation. He did emphassize those bold words with very strong tone. I am wondering why Taiwanese news medias aren't broadcasting this kind of therrible declaration to people to make people more realistic about China.
