生活中无处不在的几何

2018-06-06 14:58 来源：新华网

几何学的应用在我们的日常生活中无处不在：车辆的轮胎选用圆形，这样阻力才会最小；房屋的顶梁选用三角形，因为三角形有稳定性；蜜蜂做的蜂巢筑成正六边形，因为空间利用率最大……几何学应用广泛，解决了我们生活中的很多问题，那么，几何学到底是怎么产生的呢？

几何学的英文是Geometry，是从希腊语演变而来的，其原意是土地测量，后被我国数学家徐光启翻译成“几何学”。在四千年前的古埃及，每当尼罗河洪水泛滥，都会把两岸的土地淹没。水退后，原本分好的土地就会变得界线不清，需要重新测绘。长此以往，人们积累了许多测量土地的知识，这便形成了几何学的初步知识。

后来，希腊人跟埃及人通商，从埃及学到了测量与绘画等几何初步知识，希腊人在此基础上逐步完善、充实，逐渐将几何学发展成一门系统的学问。

在几何学的发展过程中，有一个人起到了很大的作用，他就是欧几里得。公元前338年，欧几里得将当时的几何学知识进行系统的总结和整理，并撰写《几何原本》。1607年，徐光启和西方人利玛窦合作，第一次把欧几里得的《几何原本》介绍到中国。欧几里得的《几何原本》在几何学史上具有深远的影响，直到现在，很多几何学课本都是以《几何原本》为依据编写而成。

此后，几何学的发展又出现了两个重要转折点，第一是笛卡儿在《方法论》的附录《几何》中，首次将坐标引入几何，从此几何问题能以代数的形式来表达和解决；第二是克莱因、希尔伯特等人对几何学的现代化。克莱因应用群论的观点将几何变换视为特定不变量约束下的变换群。而希尔伯特为几何奠定了科学的公理化基础，对整个数学的严密化具有重要的先导作用。

虽然几何学源自国外，但在我国，几何学的研究也有着悠久的历史。在距今约4350—3950年前的黑陶文化时期，陶器上就有菱形、正方形和圆内接正方形等许多几何图形花纹。先秦时期，墨翟所著的《墨经》里也记录了几何图形的一些知识。另外，著名的《九章算术》里记载了土地面积和物体体积的计算方法。《周髀算经》里，记载了直角三角形三边之间的关系。

\title{\bf Announcement 409: Various Publication Projects on the Division by Zero\\

(2018.1.29.)}

\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 Aristoteles (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 Brhmasphuasiddhnta (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 two global book manuscripts \cite{s18} with 154 pages and \cite{so18} with many figures for some general people. Their main points are:

\begin{itemize}

\item The division by zero and division by zero calculus are new elementary and fundamental mathematics in the undergraduate level.

\item They introduce a new space since Aristoteles (BC384 - BC322) and Euclid (BC 3 Century - ) with many exciting new phenomena and properties with general interest, not specialized and difficult topics. However, their properties are mysterious and very attractive.

\item The contents are very elementary, however very exciting with general interest.

\item The contents give great impacts to our basic ideas on the universe and human beings.

\end{itemize}

Meanwhile, the representations of the contents are very important and delicate with delicate feelings to the division by zero with a long and mysterious history. Therefore, we hope the representations of the division by zero as follows:

\begin{itemize}

\item

Various book publications by many native languages and with the author's idea and feelings.

\item

Some publications are like arts and some comic style books with pictures.

\item

Some T shirts design, some pictures, monument design may be considered.

\end{itemize}

The authors above may be expected to contribute to our culture, education, common communications and enjoyments.

\medskip

For the people having the interest on the above projects, we will send our book sources with many figure files.

\medskip

How will be our project introducing our new world since Euclid?

\medskip

Of course, as mathematicians we have to publish new books on

\medskip

Calculus, Differential Equations and Complex Analysis, at least and soon, in order to {\bf correct them} in some complete and beautiful ways.

\medskip

Our topics will be interested in over 1000 millions people over the world on the world history.
