Bayes' theorem 是概率論中的一個(gè)基本定理，幫助「概率」這一學(xué)科建立起了和「數(shù)學(xué)」之間的關(guān)聯(lián)，在實(shí)際運(yùn)用中也可以用來(lái)描述人的直覺(jué)，Harold Jeffreys 把 Bayes' theorem 類比為幾何學(xué)中的畢達(dá)哥拉斯定理
Bayes’ theorem is named after Reverend Thomas Bayes (1701–1761), who first provided an equation that allows new evidence to update beliefs in his An Essay towards solving a Problem in the Doctrine of Chances (1763). It was further developed by Pierre-Simon Laplace, who first published the modern formulation in his 1812 "Théorie analytique des probabilités". Sir Harold Jeffreys put Bayes’ algorithm and Laplace's formulation on an axiomatic basis. Jeffreys wrote that Bayes' theorem "is to the theory of probability what the Pythagorean theorem is to geometry".
Bayes 沒(méi)有覺(jué)得這個(gè)定理有那么重要，他死后親戚們找他的朋友 Richard Price 看看在遺物里面有沒(méi)有什么可以發(fā)表的東西，才不小心找到了這個(gè)定理~

Ve先生的講解里面融入了一些他自己的觀點(diǎn)，確實(shí)，Bayes' theorem 雖然可以幫你逐漸的接近真相，但是無(wú)法解決根本性的「變革」問(wèn)題：
