(見&lt;a href="http://www.wired.com/wiredscience/2011/07/baboon-stress/"&gt;這裡&lt;/a&gt;)&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;通常, 在權力最頂端的, 都是最孔武有力, 身體質素最好的.&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;b&gt;人類的社會&lt;/b&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;人類社會, 爭取到最高權力, 未必是靠力量, 更可能是靠智慧.  所以擁有最高權力, 不代表身體質素最佳. 可能因為如此, 追尋權力的慾望, 最追求子女數目的慾望, 最始分道揚鏢.&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;另外, 因為精細的分工,  導致權力的分散.  行行出狀元,  成了狀元, 不難得到異性的稱睞. 於是人類又開始追求"知識極優化".&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;但「知識」是難以量化的, 可以比較的是「財富」. 結果, 追求"財富極大化"成了多數人的目標.&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;b&gt;金錢世界&lt;/b&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;大約三千年前, 貨幣出現了.   追求財富, 是追求多幾隻羊? 多幾塊田? 多幾間屋? 有了貨幣, 財富有了個相對客觀的標準.  於是, 人類又追求"金錢極大化".&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;隨着人口暴升,  "子女數目極大化"這個目標基本消失了. &lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;隨着高學歷人口增加, 知識似乎未必可以改變命運,  "知識極優化"也失去光環.&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;隨着社會趨向民主,  "權力極大化"的吸引力, 比不上"金錢極大化".  即使在獨裁社會, 追求權力的真正目標, 似乎還是追求金錢.&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;終於到了現今社會, 追求"金錢極大化"幾乎成為唯一標準.&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;&lt;b&gt;展望未來&lt;/b&gt;&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;不過, 正如演化史上的三葉蟲及恐龍, 即使獨大也不能永遠.&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;"金錢極大化"可以獨大多久, 沒有人說得準.  已經有人開始疾呼, 要追求優質生活. &lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;究竟將來有甚麼"利益極大化"可以取代"金錢極大化"?  我這一代, 怕且也不可能知道.&lt;/div&gt;&lt;div&gt;&lt;br /&gt;&lt;/div&gt;&lt;div&gt;[本文純粹臆測, 如有雷同, 實屬快事!]&lt;/div&gt;&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1'

type='text'>半人半菌</title><content type='html'>還記得1986年的《&lt;a href="http://en.wikipedia.org/wiki/The_Fly_%281986_film%29"&gt;蒼蠅人&lt;/a&gt;》嗎? 這套電影引發了人對半人半獸的想像及恐懼。&lt;br /&gt;&lt;br /&gt;跟着在2005年, 開始真的出現半人半獸胚胎的研究, 包括中國的半人半兔, 及英國的半人半牛。 但這些都維持在胚胎階殷。&lt;br /&gt;&lt;br /&gt;及至今年, 科學家終於親眼目睹, 半人半細菌的合成品!&lt;br /&gt;&lt;br /&gt;不過, 這半人半菌並不是一班瘋狂科學家的傑作, 而是一種可以引起&lt;a

Ancient Maya Temples Were Giant Loudspeakers?&lt;/a&gt;&lt;br /&gt;&lt;br /&gt;考古學家利用電腦模擬技術, 引證了古代馬雅的廟宇建築, 具有把聲音擴大的功能, 就如一個大型的擴音機。 這不純綷是建築結構, 甚至是所用的水泥批盪, 亦有吸收或折射聲音的功能。&lt;br /&gt;&lt;br /&gt;雖然擴音的作用, 可能只是偶然。 但因為廟宇是祭師宣示神諭的地方, 世界各地的廟宇或多或少, 都有着把聲音「神秘化」的功能--再加上馬雅人也創作很多獨特的樂器--所以也不能排除是馬雅人特登作出的建築設計。&lt;br /&gt;&lt;br /&gt;&lt;img

但即使看似一樣的外觀, 其習性可能南轅北轍, 所以目前最受接受的定義, 乃由&lt;a href="http://en.wikipedia.org/wiki/Ernst_Mayr" title="Ernst Mayr" class="mw-redirect"&gt;Ernst Mayr&lt;/a&gt;提議, 以可否交配誔下能生育的新一代, 來決定是不是同一物種。   (注: 獅與虎交配所生下的獅虎或虎獅, 以及馬與驢交配所生的騾, 都不能生育!)&lt;br /&gt;&lt;br /&gt;這定義有兩個問題。 無性繁殖的生物不會交配, 總不成把每一隻單一個體說成一個物種; 有些單性生物, 需要其他沒相干的物種的性刺激才可生育!&lt;br /&gt;&lt;br /&gt;另外, 要觀察牠們的性行為亦有難度。 於是基因圖譜, 便成了另一個物種分類的方法。&lt;br /&gt;&lt;br /&gt;細箘無性繁殖, 不會交配, 但不同的細箘卻可以交換基因;  單性生物, 雖則也有性行為, 但卻沒有基因轉換。 用基因來定義, 似乎解決了問題, 但事情往往不是這麼簡單!&lt;br /&gt;&lt;br /&gt;最近的&lt;a href="http://www.biomedcentral.com/1741-7007/5/57/"&gt;長頸鹿研究&lt;/a&gt;,  加入新的轉折:&lt;br /&gt;&lt;br /&gt;在非洲大陸的研究, 發現野生長頸鹿很清楚地分為六種基因差異頗大的群組, 可以看成六個不同的物種。&lt;br /&gt;&lt;br /&gt;吊詭的事, 這不同的群組, 即使在野外也可以互相交配, 誔下可生育的一代, 所以用傳統觀念, 只是一個物種--但不知怎麼的環境因素,  這些雜交長頸鹿不能在野外存活下來!  (注: 在動物園內可以生存。〉&lt;br /&gt;&lt;br /&gt;一種, 還是六種? 這不只是科學定義, 對動物保育也是難題。 長頸鹿是數目還很充足的一個物種, 還是情況不甚樂觀的六個物種?&lt;br /&gt;&lt;br /&gt;這個問題, 肯定會在很多生物出現, 亦將引起無盡的爭論...&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/21683040-2497200825783600258?l=wshun.blogspot.com' alt='' /&gt;&lt;/div&gt;</content><link rel='related' href='http://discovermagazine.com/2010/jun/08-when-animals-attack-attempts-categorize-them' title='長頸鹿是六種動物?'/><link rel='replies' type='application/atom+xml' href='http://wshun.blogspot.com/feeds/2497200825783600258/comments/default' title='Post Comments'/><link rel='replies' type='text/html' href='http://www.blogger.com/comment.g?blogID=21683040&amp;postID=2497200825783600258' title='0 Comments'/><link rel='edit' type='application/atom+xml' href='http://www.blogger.com/feeds/21683040/posts/default/2497200825783600258'/><link rel='self' type='application/atom+xml' href='http://www.blogger.com/feeds/21683040/posts/default/2497200825783600258'/><link rel='alternate' type='text/html' href='http://wshun.blogspot.com/2010/11/blog-post_23.html' title='長頸鹿是六種動物?'/><author><name>Cheung Wai-Shun</name><uri>https://profiles.google.com/113899773330384487431</uri><email>noreply@blogger.com</email><gd:image rel='http://schemas.google.com/g/2005#thumbnail' width='32' height='32' src='//lh4.googleusercontent.com/-KXI3d8esq4Q/AAAAAAAAAAI/AAAAAAAAPXs/ov1Znm09ses/s512-c/photo.jpg'/></author><thr:total>0</thr:total></entry><entry><id>tag:blogger.com,1999:blog-21683040.post-7327063729486928538</id><published>2010-11-22T05:24:00.000-08:00</published><updated>2010-11-22T05:24:26.266-08:00</updated><title type='text'>三維玻璃打印</title><content type='html'>資料來源: &lt;a href="http://www.shapeways.com/blog/archives/653-Amazing-3D-Printed-Glass.html"&gt;Shapeways Blog | Amazing 3D Printed Glass&lt;/a&gt;&lt;br /&gt;&lt;br /&gt;突破金屬及塑膠的限制, &lt;a href="http://www.shapeways.com/" target="_blank"&gt;Shapeways&lt;/a&gt;利用&lt;a href="http://www.shapeways.com/materials/milky_white_matte_glass" target="_blank"&gt;玻璃&lt;/a&gt;作為立體打印的材料。 下圖的花瓶就是打印成形後, 再以傳統方法着色成:&lt;br /&gt;&lt;br /&gt;&lt;img style="border: 0px none;

擁有與成年血細胞&lt;a href="http://en.wikipedia.org/wiki/Fetal_hemoglobin" target="_self"&gt;不同的血紅素&lt;/a&gt;, 會更緊的抓住氧氣, 亦因而有更大機會成為癌細胞. 新技巧不經過原始細胞階段, 會直接變為成年血液, 更為安全有用.&lt;/p&gt;&lt;p&gt;由Mickie Bhatia為首的一群科學家, 把帶着&lt;a href="http://en.wikipedia.org/wiki/Oct-4" target="_self"&gt;OCT4基因&lt;/a&gt;的無害病毒注入皮膚細胞, 把細胞的生長程序稍微回轉, 然後放入一組稱為cytokines的細胞成長激素內, 直接指導變化成為紅血球或白血球. 能控製血球生成, 是臨牀治療的一個突破:&lt;br /&gt;&lt;/p&gt;&lt;p style="padding-left: 30px;"&gt; 「Mickie Bhatia說: 『如果該病人決少某種血液細胞, 我們可以與以幫助, 使其可以製造該細胞.』」 (&lt;a href="http://www.guardian.co.uk/science/2010/nov/08/skin-cells-blood"&gt;The

還有很多測試要做. 但這是目前最有前景的方法.』」 (&lt;a href="http://www.nature.com/news/2010/101107/full/news.2010.588.html" target="_self"&gt;Nature News&lt;/a&gt;)&lt;/p&gt; &lt;p&gt;一個永恆的擔心, 是我們對人造血的認識不足.&lt;/p&gt; &lt;p style="padding-left: 30px;"&gt;「幹細胞專家George Daley說: 『改變基因的操作方法, 雖然不改變基因本身, 但亦可能導致很大的差異.  畢竟, 在人體內生成血液, 或在試管內製造血液, 是兩個非常不同的程序.』」 (&lt;a

Mandelbrot&lt;/a&gt;(1924年11月20日 – 2010年10月14日)生於波蘭, 長於法國, 主要於美國從事研究工作。&lt;br /&gt;&lt;br /&gt;&lt;img

wikipedia&lt;/span&gt;&lt;br /&gt;&lt;br /&gt;他把多個數學原本不同的領域, 連成一起, 組成一門新學問:  碎形( &lt;a href="http://en.wikipedia.org/wiki/Fractal" title="Fractal"&gt;fractal&lt;/a&gt;)。事實上, fractal這個字, 就是源自他的名著《&lt;i&gt;&lt;a href="http://en.wikipedia.org/wiki/The_Fractal_Geometry_of_Nature" title="The Fractal Geometry of Nature"&gt;The Fractal Geometry of Nature&lt;/a&gt;&lt;/i&gt;&lt;span style="text-decoration: underline;"&gt;&lt;/span&gt;》。&lt;br /&gt;&lt;br /&gt;碎形的研究, 通常包括"自我相似"(&lt;a href="http://en.wikipedia.org/wiki/Self-similarity" title="Self-similarity"&gt;self-similarity&lt;/a&gt;, 即局部與全體相似), "尺度不變量"(&lt;a href="http://en.wikipedia.org/wiki/Scale_invariance" title="Scale invariance"&gt;scale invariance&lt;/a&gt;, 放大縮小形象看來不變), 以及"非整數維度" (&lt;a href="http://en.wikipedia.org/wiki/Hausdorff_dimension" title="Hausdorff dimension"&gt;Hausdorff dimension&lt;/a&gt;, 維數可以不是1,2,3而是任何數字), 最經典的例子, 是由他人發現卻由Mandelbrot發揚光大的&lt;a href="http://en.wikipedia.org/wiki/Mandelbrot_set" title="Mandelbrot set"&gt;Mandelbrot set&lt;/a&gt;:&lt;br /&gt;&lt;br /&gt;&lt;img

看我的&lt;a href="http://wshun.blogspot.com/2010/09/blog-post_3503.html"&gt;自然分形&lt;/a&gt;。&lt;br /&gt;&lt;br /&gt;但Mandelbrot最關注的, 是經濟學上的分形: 金融圖表。 十年, 十日, 或者十分鐘, 股價的圖表看起來, 沒有甚麼分別, 是一個分形。 所以除了粗糙的估計, 是不可能準確預測股價的上落。Mandelbrot晚年, 主要是推動金融業改變他視為混脹的圖表分析, 但卻被受忽略。他的無奈, 見於著作《&lt;a style="font-style: italic;" href="http://wshun.blogspot.com/2008/11/blog-post_14.html"&gt;The (mis)behaviour of markets&lt;/a&gt;》之中。&lt;br /&gt;&lt;br /&gt;上週四, Mandelbrot離我們而去, 享年85。&lt;div class="blogger-post-footer"&gt;&lt;img width='1' height='1'

/&gt;太空飛行, 一向是各國軍隊的領域, 現在遂步向私人開放。維珍集團的創辦人&lt;a href="http://en.wikipedia.org/wiki/Richard_Branson"&gt;Richard Branson&lt;/a&gt;為此投放了大量金錢。這是一個極度冒險的投資,  能否真的成功誰也說不準。 眼紅一點的, 可以說是有錢人的玩意, 而太空旅行初期, 確是只有小數有錢人有財力參加, 但期望有朝一日,  普羅大眾也可以參與!&lt;br /&gt;&lt;br /&gt;為甚麼香港的富豪沒有這樣的"吉士"?   如果有個地產商有種進行這些對人類未來有貢獻的投資, 或者香港人做樓奴都高興點!&lt;br /&gt;&lt;br /&gt;&lt;img
