“计算科学之父”图灵如何用数学破译自然界

很多人都听说过艾伦·图灵(Alan Turing),知道他是一位数学家和逻辑学家,在1935年发明了现代计算。他们知道图灵是一位密码学家,破译了纳粹的Enigma密码,帮助同盟国赢得了第二次世界大战。他们还知道,图灵是同性恋权利的殉难者,在被起诉并被判处化学阉割后,他于1954年吃了一个涂有氰化物的苹果,自杀身亡。
但很少有人知道图灵是一位博物学家,他用数学来解释自然界的图案。在他1952年发表最后一篇论文后的近半个世纪里,化学家和生物数学家们开始意识到,他后期的工作可以用来解释他们正在解决的问题,例如,斑马鱼的条纹或猎豹的斑点是如何形成的。甚至到现在,科学家们还在从图灵的遗产中找到新的洞见。
最近一次,在周四发表在《科学》杂志(Science)上的一篇论文中,中国的化学工程师利用图灵描述的斑图生成理论阐释了一种更有效的海水淡化处理方法。海水淡化正越来越多地被用于干旱地区的饮用水和灌溉用水供给。
图灵那篇1952年的论文没有明确提到,可以通过薄膜过滤盐水来产生淡水。他是用化学解释了没有明显差别的细胞球是如何在生物体中产生形状的。
尚不清楚这为什么引起了这位早期计算机科学家的兴趣,但图灵曾对一位朋友说他想推翻目的论证,即自然界中存在的复杂图案一定是某种超自然的东西创造出来的,比如上帝。
图灵从小就是敏锐的自然观察者,他注意到许多植物包含着可能与数学相关的线索。有些植物的性状中存在斐波那契数列。这个数列的一个特征是:每个数字等于前面两个数字的和。例如,雏菊有34、55或89个花瓣。
“他当然不是一位激进的无神论者,”牛津大学(University of Oxford)的客座教授、计算生物学家乔纳森·斯温顿(Jonathan Swinton)说。他研究了图灵的后期工作和生活。“他只是认为数学非常强大,你可以用它来解释很多东西——你应该试一试。”
图灵的确尝试了。
“他提出了一种数学表达式,可以从无到有地生成形状,”斯温顿说。
在图灵的模型中,两种被他称作成形素(morphogen)的化学物质在一个空白区域相互作用。“假设你有两种成形素,一种会让动物的皮肤变黑,另一种会让动物的皮肤变白,”斯温顿博士。“如果把它们混合在一起,动物的皮肤就会变成灰色。”
但如果某种原因导致一种化学物质扩散得比另一种快,它们就会集中在间隔均匀的局部区域,形成黑色和白色的斑点或条纹。
这被称作“图灵不稳定性”。发表这篇新论文的中国研究人员断定,它可以解释盐过滤膜中出现的结构。
通过在膜上制造气泡和管道等三维图灵结构,研究人员增加了它们的渗透性。这种过滤器能够比传统过滤器更好地分离盐和水。
“我们可以用一张膜完成两到三张膜的工作,”浙江大学的研究生谭喆说。他是该论文的第一作者。这意味着如果将来用于大规模的脱盐作业,消耗的能源和成本都会降低。

\maketitle
 The Institute of Reproducing Kernels is dealing with the theory of division by zero calculus and declares that the division by zero was discovered as $0/0=1/0=z/0=0$ in a natural sense on 2014.2.2. The result shows a new basic idea on the universe and space since Aristotelēs (BC384 - BC322) and Euclid (BC 3 Century - ), and the division by zero is since Brahmagupta  (598 - 668 ?).
In particular,  Brahmagupta defined as $0/0=0$ in Brāhmasphuṭasiddhānta (628), however, our world history stated that his definition $0/0=0$ is wrong over 1300 years, but, we showed that his definition is suitable.
 For the details, see the references and the site: http://okmr.yamatoblog.net/

We wrote a global book manuscript \cite{s18} with 154 pages
 and stated in the preface and last section of the manuscript as follows:
\bigskip


{\bf Preface}
\medskip

 The division by zero has a long and mysterious story over the world (see, for example, H. G. Romig \cite{romig} and Google site with the division by zero) with its physical viewpoints since the document of zero in India on AD 628. In particular, note that Brahmagupta (598 -668 ?) established the four arithmetic operations by introducing $0$ and at the same time he defined as $0/0=0$ in
Brhmasphuasiddhnta. Our world history, however, stated that his definition $0/0=0$ is wrong over 1300 years, but, we will see that his definition is right and suitable.

 The division by zero $1/0=0/0=z/0$ itself will be quite clear and trivial with several natural extensions of the fractions against the mysterously long history, as we can see from the concepts of the Moore-Penrose generalized inverses or the Tikhonov regularization method to the fundamental equation $az=b$, whose solution leads to the definition $z =b/a$.

  However, the result (definition) will show that
      for the elementary mapping
\begin{equation}
W = \frac{1}{z},
\end{equation}
the image of $z=0$ is $W=0$ ({\bf should be defined from the form}). This fact seems to be a curious one in connection with our well-established popular image for the  point at infinity on the Riemann sphere (\cite{ahlfors}). �As the representation of the point at infinity of the Riemann sphere by the
zero $z =  0$, we will see some delicate relations between $0$ and $\infty$ which show a strong
discontinuity at the point of infinity on the Riemann sphere. We did not consider any value of the elementary function $W =1/ z $ at the origin $z = 0$, because we did not consider the division by zero
$1/ 0$ in a good way. Many and many people consider its value by the limiting like $+\infty $ and  $- \infty$ or the
point at infinity as $\infty$. However, their basic idea comes from {\bf continuity} with the common sense or
based on the basic idea of Aristotle.  --
 For the related Greece philosophy, see \cite{a,b,c}. However, as the division by zero we will consider its value of
the function $W =1 /z$ as zero at $z = 0$. We will see that this new definition is valid widely in
mathematics and mathematical sciences, see  (\cite{mos,osm}) for example. Therefore, the division by zero will give great impacts to calculus, Euclidean geometry, analytic geometry, differential equations,  complex analysis in the undergraduate level and to our basic ideas for the space and universe.

We have to arrange globally our modern mathematics in our undergraduate level. Our common sense on the division by zero will be wrong, with our basic idea on the space and the universe since Aristotle and Euclid. We would like to show clearly these facts in this book. The content is in the undergraduate level.

\bigskip
\bigskip

{\bf Conclusion}
\medskip


 Apparently, the common sense on the division by zero with a long and mysterious history is wrong and our basic idea on the space around the point at infinity is also wrong since Euclid. On the gradient or on derivatives we have a great missing since $\tan (\pi/2) = 0$. Our mathematics is also wrong in elementary mathematics on the division by zero.

This book is an elementary mathematics  on our division by zero as the first publication of  books for the topics. The contents  have wide connections to various fields beyond mathematics. The author expects the readers write some philosophy, papers and essays on the division by zero from this simple source book.

The division by zero theory may be developed and expanded greatly as in the author's conjecture whose break theory was recently given surprisingly and deeply by  Professor Qi'an Guan \cite{guan} since 30 years proposed  in \cite{s88} (the original is in \cite {s79}).

We have to arrange globally our modern mathematics with our division by zero  in our undergraduate level.

We have to change our basic ideas for our space and world.

We have to change globally our textbooks and scientific books on the division by zero.

  1. Hello, my name is Vyacheslav. Unfortunately, I do not know the name of the author of this blog. I work at the Geological Institute of the Russian Academy of Sciences, the city of Apatity, Murmansk region. I'm a geologist, I'm 29 years old.
    I have long been interested in the problem of dividing by zero, but seriously I started working on this in November 2017. And I came to the same or similar conclusions as you. I even communicated on this subject with the mathematicians of the Faculty of Mechanics and Mathematics of the Moscow State University at their forum: http://www.mathforum.ru/forum/read/1/93825/page/1/
    It is clear that they then treated me with distrust, but no one could point out to me the contradictions in algebra (field) with division by zero. And I continued my "studies" as a hobby. A month ago I learned about the articles of the authors: Saitoh S., Michiwaki H., Yamada M., Kuroda M., Yamane M., Okumura H. 2014-2018, and I realized that I am not the first to make this discovery.
    I share your confidence that the division by zero should find its reflection in nature, and I can even give some examples that I did not find in your articles. Also, I would like to share with you my modest research results - for example, on how to differentiate in a field with division by zero. In addition, I do not agree with some of your conclusions and decisions. I could send to you e-mail word-files of my results. If you're interested, tell me your e-mail.
    Have a nice day!
