雙語暢銷書《艾倫圖靈傳》第9章:退隱山林(91)

This is yielding to treatment, and it will so far as I can see, give satisfactory explanations of –

我想先研究這個，在我目前所見的範圍內，這能夠對下列問題給出解釋：

(i) Gastrulation

原腸胚形成

(ii) Polygonally symmetrical structures, e.g. starfish, flowers.

多邊對稱結構，比如海星、花朵。

(iii) Leaf arrangement, in particular the way the Fibonacci series (0,1,1,2,3,5,8,13. ...) comes to be involved.

葉子的組織形式，特別是涉及斐波納契數列的形式（0, 1，1, 2，3, 5，8, 13……）的形式。

(iv) Colour patterns on animals, e.g. stripes, spots and dappling.

動物的顏色模式，比如條紋、斑點和花紋。

(v) Pattern on nearly spherical structures such as some Radiolaria, but this is more difficult and doubtful.

近球形的結構模式，比如一些放射蟲類，但這有些難度。

I am really doing this now because it is yielding more easily to treatment. I think it is not altogether unconnected with the other problem.

我現在就在做這個，這更容易一些。但我想這與其它問題也是有關的，

The brain structure has to be one which can be achieved by the genetical embryological mechanism, and I hope that this theory that I am now working on may make clearer what restrictions this really implies.

因爲大腦結構必然是由遺傳和胚胎機制產生的。我希望通過這個理論，搞清楚這裏面有什麼樣的限制。

What you tell me about growth of neurons under stimulation is very interesting in this connection.

你說的關於神經元受激的問題非常有趣，

It suggests means by which the neurons might be made to grow so as to form a particular circuit, rather than to reach a particular place.

這說明神經元是要形成一個特定的迴路，而不是通往一個特定的目標。

Yours sincerely, A.M. Turing 8th February 1951

你真摯的朋友A.M.圖靈 1951年2月8日

A few days later, the Ferranti Mark I computer was delivered at the Manchester department, which by now had a newly built Computing Laboratory to house it.

幾天後，弗蘭蒂公司生產的馬克1號計算機送到曼徹斯特了，部署在一個專門爲它新建的計算機實驗室裏。

Alan wrote to Mike Woodger back at the NPL:

圖靈給國家物理實驗室的麥克·伍格寫信說：

Our new machine is to start arriving on Monday (12 February 1951).

我們的新機器會在星期一（1951年2月12日）交付。
