雙語暢銷書《艾倫圖靈傳》第9章:退隱山林(90)
Alan's reply made clear the connection between his interests in the logical and the physical structure of the brain:
圖靈的回覆，反映了他對大腦結構的邏輯層與物理層之間的聯繫很有興趣：
Dear Young, I think very likely our disagreements are mainly about the use of words.
親愛的楊：我們很可能只是說法不同。
I was of course fully aware that the brain would not have to do comparisons of an object with everything from teapots to clouds, and that the identification would be broken up into stages,
我當然完全認識到，大腦不需要從茶壺到雲彩逐個匹配所有事物，我也認爲"識別"的過程是分階段的，
but if the method is carried very far I should not be inclined to describe the resulting process as one of 'matching'.
但是如果在這個前提下，我認爲不應該將這個過程稱爲"匹配"。
Your problem about storage capacity achievable by means of N (1010 say) neurons with M (100 say) outlets and facilitation is capable of solution which is quite as accurate as the problem requires.
你的關於N（比如1010）個神經元和M（比如100）個輸出的存儲容量及其最簡性的問題，這是一個描述的很精確的問題。
If I understand it right, the idea is that by different trainings certain of the paths could be made effective and the others ineffective.
如果我理解的沒錯，其大意是，假設通過相應的訓練，某些路徑過變得有效，其餘的會失效，
How much information could be stored in the brain in this way?
在這種方式下，大腦可以存儲多少信息？
The answer is simply MN binary digits, for there are MN paths each capable of two states.
我的答案是，MN個二進制位，因爲一共有MN條路徑，每條路徑有兩種狀態。
If you allowed each path to have eight states (whatever that might mean) you would get 3MN...
如果你假設每條路徑有8種狀態（不知道這意味着什麼），那麼答案就是3MN……
I am afraid I am very far from the stage where I feel inclined to start asking any anatomical questions.
我恐怕還不需要諮詢關於解剖學的問題，
According to my notions of how to set about it that will not occur until quite a late stage when I have a fairly definite theory about how things are done.
我認爲這是後續的工作，在這之前，我要首先在理論層面上搞清楚它的運作機制。
At present I am not working on the problem at all, but on my mathematical theory of embryology, which I think I described to you at one time.
現在我並沒有在研究這個問題，而是在研究胚胎學的數學原理，我記得我有一次跟你講過。
