雙語暢銷書《艾倫圖靈傳》第5章:解謎接力賽(88)
The conclusion drawn would always depend upon the α priori likeliness which the experimenter had had in mind at the beginning.
To give a concrete feel to the theory, Alan liked to think in terms of a perfectly rational person obliged to make bets upon hypotheses.
爲了給出這個理論形象化認識，艾倫喜歡想象一個極理智的人基於假設來打賭。He liked the idea of betting, and put the theory into the form of odds.
他喜歡打賭這個想法，並在其中引入概率。
So in the example, the effect of the experiment would be to double the odds, one way or the other.
在前面的例子中，實驗的結果會這樣或那樣地使概率增加一倍。If further experiments were allowed, the odds would eventually increase to very large numbers although in principle, certainty would never be attained.
如果做更進一步的實驗，概率最終會增加到非常大的程度，雖然理論上說永遠無法達到100%。Alternatively, the process could be thought of as one of accumulating more and more evidence.
或者說，這個過程可以看成是在積累越來越多的證據。From this point of view, it would be more natural to think of adding something each time an experiment was made, rather than of multiplying the current odds.
從這點來看，更自然的想法是，給概率加上了一些東西，而不是乘以。This could be achieved by using logarithms.
通過引入對數，就可以形式化這個想法。The American philosopher C.S. Peirce had described a related idea in 1878, giving it the name 'weight of evidence'.
美國哲學家C.S.皮斯在1878年提出了一個相關的想法，稱爲證據權重。Just after the end of 1940, the theory began to turn into practice.
剛過1940年末，理論開始轉爲實踐。
