This work presents the fundamental principles of the emerging field of "small-worlds" theory, the idea that a hidden pattern is the key to how networks interact and exchange information, whether that network is the information highway or the firing of neurons in the brain. Highlighting groundbreaking research behind network theory, the text documents the mounting support amongst various disciplines for the small-worlds idea and demonstrates its practical applications to diverse problems - from the volatile global economy or the Human Genome Project to the spread of infectious disease or ecological damage.

    82法則(帕雷多法則)的由來:
    1.投資的隨機報酬(可以連丟十次正面硬幣的一群幸運兒)
    2.正報酬的乘數效果(這群幸運兒能下注的金額)

    難怪成功是不可複製的,誰能複製運氣呢? :p

    初始條件為鉅富的幸運兒,連續丟出十次正面,財富會變成天文數字。初始條件只有1元的幸運兒,連丟十次正面也只有1024元。

    冪次律:
    結點的連結數增加一倍,結點的數量就會減少1/2

    只要找出正確的連結,人與人之間的世界可以很小,但是這些連結眾多不同社群的橋樑其實既微弱、長距離又隨機,讓這個世界感覺既擁擠又孤單。

    在還沒接觸到這本書之前,自己對六度分隔理論就早有耳聞,因為~這理論容易讓人瑯瑯上口, 吹噓某位名人也是我朋友的朋友,自己的親身經驗則是由Facebook來見證,在玩Facebook的過程中,發現高職時候的同學,是我同事的朋友,很玄吧!不得不說一下致理名言:「這世界怎麼會那麼小」。沒錯,「小世界」一詞,會在書中出現很多次,多到會讓你誤以為這本書是在抱怨世界多麼小。其實,這本書主題就是圍繞著連結,不只是人與人之間的連結關係,而是探討為何為產生連結、如何去連結、在什麼地方連結、什麼時間連結、連結後及有何改變等內容,可以當作瞭解社會學入門書之一,另外,作者(Mark Buchanan)有出新書「隱藏的邏輯」,我多半都是在書局看,通常都是一點一點的看,這次也想把它一口氣看完XD。

    嘛,這個理論是對是錯我不知道,但是作者文筆很好,不談支微末節、東扯西拉,把一個看似不易理解的科學理論用相當簡單明瞭的方式介紹給讀者,很棒的書!!
