得證，一切都是哲學 (2)

承 1964. 05-25 得證，一切都是哲學

打破神話：
do all first links on wikipedia lead to philosophy?

Q: though i wouldn't be surprised if it's true for most articles it can't
be true for all articles. can it?

反例：
http://en.wikipedia.org/wiki/Waste_management
http://en.wikipedia.org/wiki/Sand_fence

簡單地說，這幾篇的文章品質不足，我想？或是說不夠符合標準格式。

>> 100 * 50e3 / 3.5e6
=> 1.4285714285714286

所以有約 1.4% 的文章最後沒走到哲學。

Q: what's the distribution of distances of articles from 'Philosophy'?

看圖大概接近 normal distribution 吧？不意外...

Q: what's the furthest article from 'Philosophy'?

是 Violet & Daisy, 要走 36 (35) 步。
http://en.wikipedia.org/wiki/Violet_&_Daisy

不過這是去掉像是 List of state leaders in 1977 這種的。
這個有 1001 (1000) 步........

Q: are there any other articles that are "more common" than 'Philosophy'?

當然沒有。但是以下會是很接近的：

Philosophy -> Reason -> Natural science -> Science -> Knowledge
-> Fact -> Information -> Sequence -> Mathematics -> Quantity
-> Property (philosophy) -> Modern philosophy -> Philosophy

Q: what are the common paths into 'Philosophy'?

基本上以上那條路大概是最常見的主幹，因此...
強烈建議看一下原文的圖，很清楚可以看出結構。
